In former works, we had proved that test persons with sound temporomandibular joints (TMJs) used a mandibularly fixed hinge axis (MFHA) and were able to pilot the mandible by solely two kinematical degrees of freedom. We wondered if we could evaluate the MFHA the same way for patients who had problems with their TMJs. Actually, the MFHA could be determined likewise. The results could provide information on the reason for the distortion of the movement of the TMJs, which cannot be yielded by X-ray radiographs.

Background: Peri-implant marginal bone-level (MBL) alteration represents one of the parameters included in the criteria for determining implant health.
Objective: Factors affecting peri-implant MBL alteration for 4-implant-supported fixed mandibular prostheses (4-ISFMP) were assessed.
Material & Methods: A 3-year prospective, cohort study was conducted on 44 mandibularly edentulous patients treated with 4-ISFMP.

The primary aim of the study was to reveal whether adult patients with skeletal mandibular retrognathism combined with a dental Class II relationship without craniomandibular pain show a characteristic pattern of free mandibular movements compared to patients with a Class I skeletal and dental morphology. The secondary aim was to investigate whether these characteristic structures are subject to change following combined orthodontic-surgical treatment. Free mandibular movements were measured with an ultrasound device and analyzed with computer software developed by the authors.

Free mandibular movements and their neuromuscular guidance were measured with an ultrasonic device and analyzed with computer software developed by the authors. In all patients examined, we found maxillarly- and mandibularly-fixed axes which maintain a constant distance. This guidance system is named a neuromuscularly-determined dimeric link chain.

The functional conditions of the mandible are differentiated according to the number of kinematic degrees of freedom assigned to each mandibular movement. One degree of freedom: pro- and retrusive occlusal border movement. The interplay of the TMJs with the occluding teeth determines a compulsory course which corresponds to a 4-bar-chain guidance.
