|
Authors had the patient wear the occlusal stabilization splint for 10 weeks to regain a vertical jaw relation that is consistent with the contracted length of the muscles for the patient who had a lost vertical dimension caused by the severe attrition, and abrasion of all teeth of the upper and lower dental arch.
The purpose of this study was to know the PMS concept and its technique to provide an excellent and practical method for determining an occlusal plane that will fulfill all the requirements of a correct occlusion.´
Immediately after equalizing the muscle activities of the right and left closing muscles using EM2 to the patient wearing the occlusal splint, the full mouth rehabilitation of the PAIS concept and its technique was done.
From this clinical study the following results were obtained.
1. The application of using EM2 was necessary to equalize the muscle activities of the right and left closing muscles.
2. The plane of occlusion of the lower posterior teeth was established by incorporating a Curve of Spee which is approximately the are of a four inch circle using the Broadrick occlusal plane analyzer.
3. The lingual surface of the maxillary anterior teeth was established with the long centric which had no contact at centric relation occlusion and had contact at centric occlusion without the change of the vertical dimension.
4. The occlusion of the maxillary posterior teeth was established by application of the concept of a long centric and the group functioned occlusion, utilizing a F. G. P technic in the patient´s mouth.
5. There was not any occlusal interferences between the centric relation occlusion and the centric occlusion under every mandibular movement and good results were obtained functionally and esthetically.
