Although the specific diagnosis of migraine is defined as a chronic neurological disorder characterized by recurrent moderate to severe headaches often in association with a number of autonomic nervous system symptoms it is often by our dental patients used as the general term for facial pain with often also no response to the prescribed medication. This experience I share with many colleagues and yet I have to tell you about the 36 years old man, who was referred for chronic left side facial pain he had suffered for 18 years, half of his life. He had visited many doctors and he had also been taking a lot of medication during the years.

The pain occurred almost every day and was described by the patient as migraine on the left side of his face covering the left side temple and cheek area. Mandibular movements were normal. A panoramic X-ray did not reveal any pathology and showed a temporomandibular joint condylar symmetry.Static pain could be provoked for closing of his mouth. During our conversation it became obvious that a left side latero-protrusion was an often used position for bruxism, which also could be confirmed by marked facets of his left side front teeth.

After information about the possibility to initially wear a stabilization splint part time ( during day time working hours )  in order to avoid his unilateral abuse of the left side mm temporalis and the deep portion of masseter he decided to try. The stabilization splint was designed around the retruded position of his mandible, inserted without any adjustments and checked after another 6 weeks. At that time the young man announced that he had been completely free from any facial pain since the day after the insertion of the splint. It had been worn during the day except for chewing. He also showed an oral stability without the splint in his mouth.

In conclusion: When the dental patient is telling about his or her migraine that is not responding to the, by the medical doctor, prescribed medication DO PERFORM A FUNCTIONAL EXAMINATION OF THE STOMATOGNATHIC SYSTEM. There might be a chance to help the patient and not only his or her teeth.

 

 

 

 

Indices for jaw registrations

Sometimes it can be difficult to get a relaxed mandible in the process of jaw registration in the retruded position of the mandible in as well the diagnostic phase as in the steps of treatment. It happens mostly when the patient is a heavy bruxer or when the patient seems to defend him/herself against the pressure from the hands of the dentist in the clinical situation. A condylar asymmetry may add to the clinical difficulty in getting the registration right.
With the measurements of the vertical dimensions of the temporomandibular joint condyles and the Maaxloc device at hands the above mentioned problems can definitely be reduced.It is my opinion, which to a great extent I have achieved from the dental technicians, that the registrations made in the Maaxloc system get into a more retruded position of the mandible in comparison with the manually taken clinical indices which often are protruded.This conclusion is based upon several years of cooperation with Ines Selimanovic T.I.C. laboratory, Malmoe ,Sweden, an experienced dental technician, with whom I have made comparisons of by me taken clinical indices and by her made registrations in the Maaxloc device.
In conc;usion: To avoid unnecessary and time consuming adjustments despite quality of the dental work in the ” difficult mouth “it might be worth while to become critical to the manually taken clinical registration and consider the advantage of the Maaxloc device.

Several years ago I met with and was introduced to Kenneth Wallenholm, an experienced dental technician in Stockholm, Sweden. I was giving a lecture and he was in the audience. I had talked about the recognition of temporomandibular joint condylar asymmetry, when present, and its importance for a correct registration of the mandibular position to be used as the reference position for optimal dental work clinically as well as in the dental laboratory. He had immediately understood my message and for a long time also realized that most “wax bites”, indices or ” Registrat ” accompanying dental impressions into the laboratories most frequently ended up in the trash can, never being used. The reason was that these ” wax bites ” did not provide any information about the workable intermaxillary relation. The technicians therefore rather related the upper and lower models of the jaws by hand i.e. they just tried to find the best stability between the models,maybe sometimes the intercuspal position, before they started their technical procedures to establish an acceptable occlusion. We were  both of the same opinion that such unfortunate events outside the mouth of the patient are the major reasons  for clinically unwanted adjustments of dental work before its  insertion into the mouth.

It did not take us long time until we met again and started to brain storm how to come up with a device in order to facilitate for the dentist / technician team to ascertain and improve the registration of the correct mandibular position to be used by both the professions. After many hours, many different measurements, several different drawings and a certain number of pieces of ” metal constructions ” the patent was approved and the prototype for the Maaxloc  was completed by Dentatus ( info@dentatus.se : dentatus@dentatus.com )

The Maaxloc determines the clinically correct mandibular position. The Maaxloc is not an articulator even if it is described under articulators in the list of products from Dentatus. The Maaxloc is a device to assist in finding the correct mandibular position of reference at a recognized condylar / mandibular asymmetry. The registration index produced in the Maaxloc can be  used in any articulator of your choice and can comfortably be applied in cases of craniomandibular or temporomandibular disorders,as well as in any case of prosthetic rehabilitation or orthodontic analysis. Determining the correct mandibular position of reference is of utmost importance and will help to avoid unwanted occlusal features. This includes achieving the correct incline of implants into the jaws and improving the occlusal analysis before an orthodontic treatment is initiated.

The Maaxloc is time saving and reduces pain because:

1.Symmetry in occlusal contacts between the jaws decreases the risk of failure in providing bilateral load to the stomatognathic system.

2.Less time is spent on adjustments and on remakes due to fractures in veneers and crown & bridge work, including supra structures on successfully accepted implants.

3.Shorter sessions for repetitive registrations of the mandibular positions.

4.A stable occlusion compensates a morphological asymmetry, improves the general adaptation of tissues and is especially beneficial to the edentulous patient wearing removable prostheses, with less dislocation of the prostheses.

5.Last but not least, once the individually correct mandibular position has been found, the patients immediately acknowledge their natural way of achieving and sensing oral stability

It  is my convinced opinion that the measurements of the condylar heights in a panoramic ( overview ) x-ray and  the difference between the two sides transferred into  the Maaxloc will further your clinical success and confidence.
