[Posterior vertical dimension and condylo-discal non-coordination of the temporomandibular joint. Hypothesis on correlation].

BACKGROUND: On the basis of clinical evidence, an analytic study has been carried out to verify the hypothetic correlation between reduction of the posterior vertical overlap and internal derangements. METHODS: 58 patients with temporomandibular disorders have been observed; they presented clinically a reduction of the posterior vertical dimension (RPVD) due either to the loss of molar teeth or to the molar occlusal surface abrasion or to a wrong prosthetic rehabilitation. A cephalometric exam showed a significative correspondence between the RPVD and the retruded condylar position in the glenoidae fossa with a reduction of posterior joint space in comparison with the standard values purposed by Farrar. RESULTS: The results obtained showed a possible relation between occlusal alterations and the TMJ pathology. CONCLUSIONS: The conclusion is drawn that the clinical evaluation brings to consider occlusal factors, and in particular the reduction of posterior vertical dimension may be considered as possible etiologic factors of TMJ disorders.

The condyle-fossa relationship in temporomandibular disorders. Considerations on the pathogenetic role of the disc.

AIM: The purpose of this study is to evaluate the condylar position and its variation in patients with temporomandibular joint (TMJ) disorders before and after therapy with occlusal gnathologic devices. METHODS: Twenty-five TMJ of 25 patients with temporomandibular joint disorder were examined by linear measurement of the anterior, posterior and superior joint space between the condyle and glenoid fossa through cephalometric analysis on X-ray tomography of the TMJ and by calculating the condylar position with the Pullinger and Hollender method. RESULTS: The average condylar position in the TMJ with DTM was posterior with a mean value of 22.2% and a range from 14.3% to 36%. The condylar position of 25 TMJs was: anterior 0(0%); centric 8(32%) and posterior 17(68%). After therapy with occlusal gnathologic devices the average condylar position was centric with a mean value of 0.6% and a range from 5.3% to 6.6%. The condylar position of 25 TMJs was: anterior 2(8%); centric 22(88%) and posterior 1 (14%). CONCLUSIONS: The hypothesis can be advanced that joint pathology is the consequence of the alteration of the condyle position and therefore of the mandibular movement and vice versa. Therapy with occlusal devices makes it possible to modify the condylar position by increasing the condylar capability to recapture the joint disc.

[Electrognathographic imaging of the articular click].

The study of TMJ phisiopathology by means of computerizing devices is necessary in order to make a correct diagnosis and verify the therapeutic programme. In this study the Authors analyse articular click that is one of the first and characteristic symptom of the internal derangement. The Authors show by means of elettrognatography, chewing cicles and mandibular border movements of patients affected with this particular pathology. Trascing of 135 patients suffering from tmj reciprocal click have been examined in the department of maxillary-facial of Roma "La Sapienza", surgery during the period 1987-88.
