MCB (Mandibular Cranial Balancing) splint is used when there is movement of the temporal bone and produces a splint by placing the lower jaw in a position that improves the movement of the cranial bone. (Treat at high heights, such as pivot splints or template splints .)
MDB (Mandibular Disc Balancing) splint is used when the temporal bone movement is reduced, and the splint is produced by placing the lower jaw in a position that improves the movement of the cranial bone.(Treats at lower heights like Anterior Repositioning Splint/ARS splint)
Wearing MCB splints, you can feel the movement from skull to feet in a good corrected direction.
Wearing the MCB splint, the displaced bones of the head bone move slowly in the opposite direction with increased mobility. This movement is done in all parts of the body from the shoulder to pelvic feet, and the displaced body is restored to a balanced position. The more the wrong body is straight, the more the power of the whole body increases and the less tired it becomes.
As soon as you put on a MCB splint, applied a specific location of your lower jaw, you can feel strong and balanced brain blood circulation. MCB splint can immediately correct muscle distortion promptly after you put it on. We are holding a seminar about MCB splint explicated above. For Parkinson's patients, the tremor of hands stops immediately after wearing the MCB Splint and can touch fingers which was previously untouchable.

Objectives: The present study aimed at performing a histological evaluation of the response of temporal bone tissue to a change of direction of the force vector of the mandible in relation to the base of the skull.
Material and methods: Adult rabbits were assigned into four groups with two control and four experimental animals in each group. experimental animals underwent surgery, which resulted in a change of direction of the force vector on the right temporomandibular joint. Samples were collected after 15, 30, 60 and 90 days for histological analysis.
Results: In the two-way analysis of variance, the effect of group and time was statistically significant (p<0.001). Additionally, a statistically significant interaction between group and time was observed (p<0.001). Control animals showed normal growth and development of the temporal region. In the experimental group, the change in direction of the force vector of the mandible induced significant changes in the temporal bone, with a bone modeling process, which suggests growth of this cranial structure.
Conclusions: The methodology used in this experiment allows us to conclude that the change in direction of the force vector of the mandible in relation to the skull base induces remodeling and modeling processes in the temporal bone. The resumption of normal oral functions after bone healing of the mandibular fracture appears to increase cell activation in the remodeling and modeling of the temporal bone structure. The observation of areas of temporal bone modeling shows the relevance of further investigation on the correlation between the joint structures and craniofacial growth and development.

The ALF Appliance Is Useless Without Starecta
26 June 2017 | By Starecta |
In this report, we explain why the ALF appliance is absolutely useless if it is not supplemented with the Starecta Rectifier
Many people who approach Starecta ask us what the differences are between the Rectifier (splint Starecta) and the ALF appliance. Although I understand that someone might be confused, it is necessary to understand that these two technologies are completely different and have very different purposes. For this reason, it is better not to confuse them.
The Starecta and the ALF are not alternative methods. This means that one is not better than the other. They are simply different; rather, they perform different functions. For this reason, we can say that they are complementary, which means that can be used together.
Comparing the ALF with the Starecta is like comparing the appetizer with the dessert. They are two types of treatment which perform different, not alternative, functions.
At the end of the report, you will understand why we insist that these two methods must be used together. At this point, I ask you to get comfortable and to dedicate five minutes to reading this article. We will definitely clear up a crucial question.
The first theory that is refuted is that the ALF aligns the teeth and facial bones following the osteopathic principle of bone alignment. We do not deny that it aligns the teeth, and the pursuit of symmetry and of postural improvement by this instrument and its inventors is praiseworthy, but the Starecta method has already amply demonstrated that postural symmetry is not achieved by simply aligning the bones. A much more complex procedure exists in order to achieve symmetry, as explained in the book, How I Straightened my Spine Out.
In fact, the Starecta has demonstrated that, in order to achieve symmetry, it is necessary that the cranium turns in its natural position through the use of a lever (i.e. “Lever Effect”) placed in the mouth. This lever is activated, according to the Starecta method, by the Rectifier. The Rectifier is, as of today, the only instrument able to activate the lever.
This is why we can say, with absolute certainty, that the ALF, by itself, does not allow for postural rebalancing to be attained. It goes without saying that the ALF is not even able to remedy twisting, back pains, to remedy kyphosis, or other symptoms connected with poor posture.
The ALF is only a type of orthodontic treatment (it aligns teeth and stabilizes the occlusion). And yet, this orthodontic appliance may have a lot of potential, as we will see in the following, but such potential can only be activated with the Starecta. Without the Starecta, the ALF is like an army without a commander.
For this reason, if used without the Starecta, we can say that the ALF (Alternative Lightwire Functionals) is used to perform two functions: stabilize an orthodontic job and expand the palate. It is not used for anything else.
The Differences between the Rectifier and the ALF
As you have probably understood, we are not critics of the ALF; rather, we attribute great importance to it, but only under certain conditions. Later on, we will speak about these conditions. Now, it is better to understand what the fundamental differences between the Rectifier and the ALF are. This way, one will immediately understand that it is absolutely stupid to compare them.
The ALF has the ability to:
◾ Stabilize an occlusion by means of an appliance which allows for a certain freedom of micro-movements of the maxillary bones
◾ Stabilize treatments of an orthodontic nature
◾ Expand the palate
◾ Stop post orthodontic treatment relapse
◾ Act as an osteopathic treatment for the cranium
On the other hand, the ALF is not able to:
◾ Realign the cranium, mandible and spinal column in order to give symmetry to the body
◾ Activate the molar lever which places the spinal column in traction in order to straighten kyphosis and lordosis
The Rectifier (splint Starecta) has the ability to:
◾ Realign the cranium, mandible and spinal column
◾ Cause postural and muscular-skeletal realignment of the body on three spatial planes
◾ Place the spinal column in traction
◾ Symmetrically rebalance the muscles of the body (among these, even the tongue)
◾ Decompress the vertebrae, muscles and organs
◾ Improve respiration capacity and expansion of the ribcage
On the other hand, the Rectifier is not able to:
◾ Work as an orthodontic treatment
◾ Realign the teeth
Due to this, it immediately appears clear as to how the two instruments are not at all alternatives of each other, but completely different and, therefore, complementary. And yet, in spite of this, there are people who continue to ask us if the ALF or the Rectifier is better. We hope that reading this article might definitively clear up their doubts.
Having said it in the simplest terms, we can affirm that the ALF has the objective of making the face more harmonious and aesthetically more pleasing. Vice versa, the Rectifier has the task of muscular-skeletally rebalancing of the entire body.
Using these two instruments together is the best way to have the maximum postural and aesthetic benefits. In fact, going more into specifics, we have to say that the Rectifier acts on single bone segments and is capable of moving them in space towards their correct posture.
Among these bone segments is the cranium which is made up of more bones connected together in specific points. The substantial difference is that the Rectifier completely lifts the head and brings it to its correct posture, freeing it from multiple symptoms, muscular contractions, asymmetries and anything else.
Nevertheless, the Rectifier is not capable of moving the single bones which make up the cranium (think of a puzzle). For this type of job, it is indispensible to use the ALF which, for its part, is not capable to act upon the posture of the head except in a minimal part and in an indirect manner (not always advantageously).
Nevertheless the ALF is capable of modifying the layout of all the small bones which make up the cranium. This is why we can talk about neurocranial-facial reconstruction. Combining the effects of the two means having the maximum symmetry and the best bodily posture possible.
Demonstrating the fact that it has to do with complementary, not alternative, instruments, you must know that when taken singularly, they also exhibit negative sides. The negative sides of these instruments are:
– The ALF, as with all orthodontic treatments which expand the palate, causes the loss of vertical space (molar height in the posterior area). Such loss produces an unfavorable molar lever which leads to a worsening of postural conditions (increase in kyphosis, lordosis, scoliosis, painful symptoms, etc.).
– The Rectifier causes an increase in the vertical space in order to realign and place in traction the spinal column. That can cause, in the most serious cases, an empty space in the molar area which must be closed with an orthodontic treatment.
But, used at the same time, they compensate for the negative aspects that the two instruments present if used separately.
The Misinformation about the ALF
Unfortunately, there is a group of people who propose the ALF appliance as a panacea for all ailments. According to them, the ALF would be able to improve cognitive functions, respiration, lingual posture, the balancing of cranial bones, posture in general, etc.
As it is described, it truly seems to be an effective instrument. There is a problem, however: the daily apology made about this application crumbles like a house of cards if the view of the whole is lost. A more acute eye immediately notes that the ALF lacks those fundamental components which allow for the balancing of the human body in a real manner.
In fact, the components necessary for balancing the human posture are the vertical-posterior space, which activates the molar lever in order to place the spinal column in traction (molar and premolar height), and the cranial-mandibular symmetry which impacts the entire body.
We repeat it: the ALF is advertised (for obvious economic interests) also as the solver of problems regarding bodily balance, facial symmetry and correct posture. And yet, it is in no way capable of solving them.
We are not saying that the ALF is an appliance that does not work, on the contrary; we are affirming that it is very often passed off for something that it is not, and only for commercial ends. For this reason, it is necessary to make clear what this appliance is capable of doing and not doing.
Not by chance, the ALF appliance was born as an orthodontic treatment which performs a double function: to stabilize already completed orthodontic treatments and expand the dental arches. In fact, the ALF exerts constant lateral pressure of the inside of the mouth towards the outside, causing an expansion of the arches.
The constant pressure, in theory, should cause a minimal increase of the cranial volume. The cranial bones move apart from each other and the sutures stretch, thus allowing a cranial expansion. This way, subsequently, there should be a readjustment of all of the cranial bones.
In theory, the concept is correct, but, in practice, the reality is very different than what is presented by the supporters of the ALF. In order to realign posture and to make the body symmetrical, it is necessary to apply new fundamental principles that the Starecta method, in recent years, has underscored insistently.
For example, if there is a readjustment of the cranial bones in an unbalanced body, the ALF’s work has totally useless, or even damaging, results in cases of loss of vertical space.
Moreover, as already stated, all of the practices of palatal expansion lead to a loss of vertical space (dental height). That leads, consequently, to a loss of dental support of the cranium in the premolar and molar area. How could such an appliance bring benefits to the posture? Such an appliance would only favor a collapse of the cranium.
PLEASE REMEMBER: The more you expand the palate, you lose vertical space and, therefore, support for the cranium which collapses.
For this reason, we can say that the so-called job of stabilization of the ALF appliance, in reality, is worthless if the causes which generate the cranial mandibular twisting are not removed, the lateral deviations caused by asymmetrical chewing loads and, above all, the lack of an adequate dental height (vertical space). In fact, the dental height is necessary to push the cranium up, to stretch the spinal column and, therefore, stand erect without effort.
The ALF can have beneficial effects only on people who already have an optimum vertical space (dental height in the premolar and molar area), while those who lack vertical space cannot derive any benefit from the ALF. This is the only truth!
For this reason, before putting on the ALF appliance, it is necessary to correct postural cranial-cervical-spinal problems with the only instrument capable of doing it: the Rectifier.
After having corrected the asymmetries of the entire stomatognathic apparatus, after having corrected the lateral deviations, the twisting and all the asymmetrical loads of the face, after having recovered an adequate vertical space (dental height which supports the cranium upward in an ideal posture), it is possible to think about beginning a job with the ALF in order to have effective, real and lasting benefits.
If the ALF is used without first improving the global posture of the body and of the cranial-cervical-spinal system, it means that the asymmetries of the stomatognathic apparatus, the lateral deviations and the lack of vertical space (dental height) will keep the ALF from producing any benefit.
This is why the Starecta team insists, with great determination, upon the importance of correcting, first, the cranial-cervical-spinal system, and only after adopting any other orthodontic treatment.

Effectiveness of Osteopathic Manipulative Treatment Versus Osteopathy in the Cranial Field in Temporomandibular Disorders - A Pilot Study
Christina Gesslbauer 1, Nadja Vavti 1, Mohammad Keilani 1, Michael Mickel 1, Richard Crevenna 1
PMID: 28029069 DOI: 10.1080/09638288.2016.1269368
Purpose: Temporomandibular disorders are a common musculoskeletal condition causing severe pain, physical and psychological disability. The effect and evidence of osteopathic manipulative treatment and osteopathy in the cranial field is scarce and their use are controversial. The purpose of this pilot study was to evaluate the effectiveness of osteopathic manipulative treatment and osteopathy in the cranial field in temporomandibular disorders.
Methods: A randomized clinical trial in patients with temporomandibular disorders was performed. Forty female subjects with long-term temporomandibular disorders (>3 months) were included. At enrollment, subjects were randomly assigned into two groups: (1) osteopathic manipulative treatment group (20 female patients) and (2) osteopathy in the cranial field group (20 female patients). Examination was performed at baseline (E0) and at the end of the last treatment (E1), consisting of subjective pain intensity with the Visual Analog Scale, Helkimo Index and SF-36 Health Survey. Subjects had five treatments, once a week. 36 subjects completed the study (33.7 ± 10.3 y).
Results: Patients in both groups showed significant reduction in Visual Analog Scale score (osteopathic manipulative treatment group: p = 0.001; osteopathy in the cranial field group: p< 0.001), Helkimo Index (osteopathic manipulative treatment group: p = 0.02; osteopathy in the cranial field group: p = 0.003) and a significant improvement in the SF-36 Health Survey - subscale "Bodily Pain" (osteopathic manipulative treatment group: p = 0.04; osteopathy in the cranial field group: p = 0.007) after five treatments (E1). All subjects (n = 36) also showed significant improvements in the above named parameters after five treatments (E1): Visual Analog Scale score (p< 0.001), Helkimo Index (p< 0.001), SF-36 Health Survey - subscale "Bodily Pain" (p = 0.001). The differences between the two groups were not statistically significant for any of the three target parameters.
Conclusion: Both therapeutic modalities had similar clinical results. The findings of this pilot trial support the use of osteopathic manipulative treatment and osteopathy in the cranial field as an effective treatment modality in patients with temporomandibular disorders. The positive results in both treatment groups should encourage further research on osteopathic manipulative treatment and osteopathy in the cranial field and support the importance of an interdisciplinary collaboration in patients with temporomandibular disorders. Implications for rehabilitation Temporomandibular disorders are the second most prevalent musculoskeletal condition with a negative impact on physical and psychological factors. There are a variety of options to treat temporomandibular disorders. This pilot study demonstrates the reduction of pain, the improvement of temporomandibular joint dysfunction and the positive impact on quality of life after osteopathic manipulative treatment and osteopathy in the cranial field. Our findings support the use of osteopathic manipulative treatment and osteopathy in the cranial field and should encourage further research on osteopathic manipulative treatment and osteopathy in the cranial field in patients with temporomandibular disorders. Rehabilitation experts should consider osteopathic manipulative treatment and osteopathy in the cranial field as a beneficial treatment option for temporomandibular disorders.

Immediate Effect of the Resilient Splint Evaluated Using Surface Electromyography in Patients With TMD
André Luís Botelho 1, Bruno Caetano Silva, Flávio Henrique Umeda Gentil, Chiarella Sforza, Marco Antonio Moreira Rodrigues da Silva
PMID: 21032981 DOI: 10.1179/crn.2010.034
The aim of this study was to analyze the immediate effect of resilient splints through surface electromyography testing and to compare the findings with the electromyographic profiles of asymptomatic subjects. The participants were 30 subjects, 15 patients with TMD (TMD Group) and 15 healthy subjects (Control Group), classified according to Research Diagnostic Criteria (RDC/TMD) Axis I. A resilient occlusal splint was made for each patient in the TMD Group from two mm thick silicon to cover all teeth. The EMG examination was performed before and immediately after installing the splint. Three tests were performed as follows: 1. Maximum Voluntary Contraction (MVC) using cotton rolls (standards test); 2. MVC in maximal intercuspation position; and 3. MVC with the splint in position. The EMG signal was recorded for five seconds. EMG indices were calculated to assess muscle symmetry, jaw torque, and impact. There was a statistically significant difference when comparing the results among the study groups. The symmetry index values in the Control Group were higher than the TMD Initial Group and similar to the TMD Group after the installation of the splint. The index values of torque were higher in TMD Initial Group when compared with the Controls. Impact values were lower than normal values in the TMD Initial Group and restored upon installation of the splint. The resilient occlusal splints may be used as complementary or adjunctive treatment of temporomandibular disorders.

Bruxism and Temporal Bone Hypermobility in Patients With Multiple Sclerosis
David E Williams 1, John E Lynch, Vidhi Doshi, G Dave Singh, Alan R Hargens
PMID: 22586826 DOI: 10.1179/crn.2011.026
In this study, the authors investigated the link between jaw clenching/bruxism and temporal bone movement associated with multiple sclerosis (MS). Twenty-one subjects participated in this study (10 patients with MS and 11 controls). To quantify the change in intracranial dimension between the endocranial surfaces of the temporal bones during jaw clenching, an ultrasonic pulsed phase locked loop (PPLL) device was used. A sustained jaw clenching force of 100 lbs was used to measure the mean change in acoustic pathlength (delta L) as the measure of intracranial distance. In the control subjects the mean delta L was 0.27 mm +/- 0.24. In subjects with MS the mean delta L was 1.71 mm +/- 1.18 (p<0.001). The increase in magnitude of bi-temporal bone intracranial expansion was approximately six times greater in subjects with MS compared to controls. Therefore, jaw clenching/bruxism is associated with more marked displacement of the temporal bones and expansion of the cranial cavity in patients with MS than in control subjects.

The Cerebral Representation of Temporomandibular Joint Occlusion and Its Alternation by Occlusal Splints
Martin Lotze 1, Christian Lucas, Martin Domin, Bernd Kordass
PMID: 22102437 DOI: 10.1002/hbm.21466
Occlusal splints are a common and effective therapy for temporomandibular joint disorder. Latest hypotheses on the impact of occlusal splints suggest an altered cerebral control on the occlusion movements after using a splint. However, the impact of using a splint during chewing on its cerebral representation is quite unknown. We used functional magnetic resonance imaging (fMRI) to investigate brain activities during occlusal function in centric occlusion on natural teeth or on occlusal splints in fifteen healthy subjects. Comparisons between conditions revealed an increased activation for the bilateral occlusion without a splint in bilateral primary and secondary sensorimotor areas, the putamen, inferior parietal and prefrontal cortex (left dorsal and bilateral orbital) and anterior insular. In contrast, using a splint increased activation in the bilateral prefrontal lobe (bilateral BA 10), bilateral temporo-parietal (BA 39), occipital and cerebellar hemispheres. An additionally applied individually based evaluation of representation sites in regions of interest demonstrated that the somatotopic representation for both conditions in the pre- and postcentral gyri did not significantly differ. Furthermore, this analysis confirmed the decreasing effect of the splint on bilateral primary and secondary motor and somatosensory cortical activation. In contrast to the decreasing effect on sensorimotor areas, an increased level of activity in the fronto-parieto-occipital and cerebellar network might be associated with the therapeutic effect of occlusal splints.
Touch—More Than a Basic Science
Mitchell L. Elkiss, DO; John A. Jerome, PhD
The Journal of the American Osteopathic Association, August 2012, Vol. 112, 514-517.
The potency of touch in osteopathic manipulative treatment (OMT) is physically realized within the musculoskeletal, immune, nervous, and endocrine systems. Psychologically, touch supports a verbal and tactile interaction that is both diagnostic and therapeutic. Touch is a 2-way street that adds meaning and depth to the patient-physician experience. The relationship between touching and being touched offers a potentially powerful and intense deepening of the patient-physician relationship that emerges within the palpatory examination and treatment. Empathic communication, through word or deed, allows a therapeutic, synchronized healing to occur. In the present article, the authors provide a rationale to sensitize and invigorate osteopathic physicians to routinely evaluate and treat patients using their skillful touch.
The musculoskeletal, immune, nervous, and endocrine (MINE) systems interact in response to low-threshold mechanical stimulation, which is perceived as touch, and to nociceptive input, which is perceived as pain. Dysregulation in the MINE systems, expressed through the musculoskeletal system as somatic dysfunction, can be diagnosed during palpatory examination.

To evaluate three‐dimensional (3D) craniofacial changes induced by a non‐surgical tooth‐bone‐borne rapid palatal expander (TBB‐RPE) according to the symmetrical pattern of expansion, to investigate the 3D changes between the sides in patients with asymmetric expansion, and to identify the related factors of asymmetric expansion.
Setting and sample population
Sixty‐six patients (mean age: 19.3 ± 5.7 years) treated with TBB‐RPE were divided into a symmetric expansion group (Group S, n = 46) or asymmetric expansion group (Group A, n = 20). Group S was subdivided into Group Ss (n = 27), with bilateral frontomaxillary suture (FMS) split, and Group Sn (n = 19), with no FMS split.
Materials and methods
Pre‐ and post‐expansion cone‐beam computed tomography images were superimposed, and the common coordinated system was set. All landmarks were designated as coordinate pairs, and treatment changes were automatically calculated. Analysis of variance was conducted for intergroup comparison of craniofacial changes, and logistic regression analysis was performed to identify the related factors of asymmetric expansion.
The frequency of asymmetric expansion was 30.3%. Group A with unilateral FMS split showed less craniofacial changes than Group Ss and more changes than Group Sn. Group A exhibited different nasomaxillary displacement between the two halves, showing greater changes in the FMS‐split side. Among the tested six variables (age, gender, Angle's classification, unilateral crossbite, maxillary cant and chin deviation), chin deviation was uniquely associated with asymmetric expansion.
Tooth‐bone‐borne rapid palatal expander had a risk of asymmetric expansion, especially in facial asymmetric patients with chin deviation, producing different craniofacial changes from symmetric expansion.

Introduction/objective: The purpose of this study was to assess whether condylar position, as depicted by magnetic resonance imaging, was an indicator of disc morphology and position.
Methods and material: One hundred and twenty two TMJs of 61 patients with temporomandibular joint disorder were examined. Condylar position, disc deformity and degree of anterior disc displacement were evaluated by using magnetic resonance imaging.
Results and discussion: Posterior condyle position was found to be the main feature of temporomandibular joints with slight and moderate anterior disc displacement. No statistical significance was found between the condylar position, and reducing and nonreducing disc positions. On the other hand, superior disc position was found to be statistically significant for centric condylar position.
Conclusion: It was concluded that posterior condyle position could indicate anterior disc displacement whereas there was no relation between the position of condyle and the disc deformity.
