[The role of MRI in the anatomic and functional assessment of the temporomandibular joint].

The aim of this study is to analyze with MRI the normal anatomy of TMJ in 12 volunteers from 30 to 35 years old. The anatomical components are described in order to provide the information for their functional evaluation with MRI. MRI is thought to be the most helpful examination in the clinical analysis of both normal and pathologic TMJ.

[Gnathologic-orthodontic protocol for Class II, division 1 with TMJ dysfunction].

The Authors present a case of Class II Division I malocclusion associated with TMJ dysfunction and treated with a gnathologic-orthodontic approach. The protocol involves five steps: extraction of third molars because not useful in the orthodontic treatment, placement of a edgewise appliance following the Tweed technique, use of a neuromuscular deprogramming appliance, an orthopedic appliance associated with physiotherapy.

[A SEM evaluation of the surface color of Dicor crowns].

With multiple measurements on Dicor crowns cast on extracted teeth and observed under SEM, we determined that the thickness of the external layer of shading porcelain has a mean value of 55 +/- 12 microns (for 4 applications). This datum must be considered so that a dimensional error is not introduced in the construction of these types of crowns.

[The maxillofacial prosthesis: palatal obturators. The principles of treatment and rehabilitation in a case of buccorhinosinusal communication].

Having analysed the causes which lead to the loss of substance from the palatal vault, the different types of communication which then result, their evolution and the consequent functional defects are identified. By describing a complex clinical case, and having taken into consideration both aims and materials, the techniques of prosthetic rehabilitation are illustrated using obturator devices. The results of the various phases are examined.

[Prosthetic rehabilitation in temporomandibular joint dysfunction based on electromyographic and radiological findings].

The authors present four clinical cases for which they used the same diagnostic approach as for the study of craniomandibular disturbances. The clinical examination provides a diagnostic clue and, consequently, orients toward the proper selection of paraclinical tests for neuromuscular and radiological investigations. After some time, prosthetic rehabilitation will also be controlled by the same means.
