[Comparative study of sagittal and coronal MRI of histological disk and temporomandibular joint specimen for examining an identity of anterior disk dislocation and anterior capsular connective tissue].

Problem: Anterior dislocation of the articular disk of the temporomandibular joint (TMJ) found by MRI tomography often presents a problem. It may persist in MRI despite improvement of articular symptoms and even be found in healthy persons free of any symptoms. Can this be explained by the similarity in structure of the anterior connective tissue of the disk and capsule and their pathological changes? Is a second coronal plane required for MRI investigation?

Material And Methods: The preauricular regions of 72 patients of the TMJ clinic were examined by oblique-sagittal and oblique-coronal MRI.

[Anterior and lateral disk and capsule tissue of the temporomandibular joint and its relevance for temporomandibular joint diagnosis].

Objective: Fibrocartilage that bears tensile stress is typically fixed bilaterally to adjacent bone by collagenous fibres. For the temporomandibular joint, such disc fixations in the anterior and lateral regions have not been described, even in MRT findings of anterior disc dislocations without reduction. By observing collagenous fibres of the anterior and lateral discuss and capsule tissue, we sought to establish whether tensile load capacities typical for fibrocartilage also apply to the discuss articularis of the mandibular joint in sagittal direction.

Canthaxanthine retinopathy.

Background: A 42-year-old white female complaining of decreased vision was examined and small golden particles were found in the macular regions of both eyes. It was ascertained that the patient had been using an oral bronzing agent, canthaxanthine (Orobronze), for the previous 10 years.

Methods: The method of deposition of these crystalline particles and their possible sequela are presented.

[Plastic skull for practical education in stomatological radiology].

A plasticmodell of a skull manufactured by Deutsches Hygienemuseum Dresden, German Democratic Republic, was produced with Ba2SO4, natural teeth and special constructions for the practical training of students in Stomatological Radiology. Examples show the radiographed x-ray-photograms.

[Individually produced open endosseous dental implants made of Bioverit glass ceramic. First report on experiences].

The glass ceramic "BIOVERIT" is characterised by biocompatibility, bioactivity and distinguished machinable treatment. The single casting in an especially dental technical laboratory pender is possible the individual production of dental implants. Described were the development of the form, the production and operation for these glass ceramic implants and first clinical results.
