FDPS finish line design and tooth preparation technique
No full textThe purpose of this research is to perform and verify the modified 50° preparation suggested by the authors. This procedure was performed with a scrupulous standardization of the tooths preparation and then of the laboratory techniques to produce a metal-ceramic crown, and the same for the crown cementation technique of on the preparation of the original sample. After the esthetic evaluations, the obtained sample was included in EPON resin and sectioned in the lingual-vestibular sense. The sections were then observed with an optical microscope in different magnifications for the final evaluations. The geometric design proposed presents the advantages of two great preparation techniques: 50° preparation and circumferential shoulder. The 50° bevel designed in first phase of preparation and the second phase of the circumferential 27° shoulder, together allowed to satisfy the following requirements: aesthetic, marginal accuracy, periodontal compliance, conservation and stability. However, this type of prosthetic preparation is not the only one, but it is one of the marginal designs in prosthetic dentistry
Restoration of anterior teeth using an indirect composite technique. Case report
Full text linkThis article presents a case report of restoration of anterior teeth using an indirect technique with composite
veneers in order to restore the dental anatomy and to provide aesthetic and function of anterior teeth. A treatment of upper anterior teeth with indirect microhybrid composite restoration was proposed to a 40-year-old woman with old discolored and fractured ceramic veneers. Upper six anterior teeth were prepared and, after impressions with VPS of maxillary arche, the composite veneers were placed. There are several advantages offered by indirect techniques compared to direct techniques. The increased practice of veneering technique with indirect composites is due to improvement in the properties of composite materials in the last years. The results are very favourable and the patient is satisfied. The restorations with composite veneers have proved durable and aesthetic, protect tooth structure and aesthetic and function is predictably

Articular disc of temporomandibular joint: an anatomical and histological study. Functional considerations
No full textThe articular disc is an important component of the temporomandibular joint, whose morphology has been studied on autopsy and biopsy materials. The normal posterior attachment of the disc is usually described as having two layers, one upper and one lower. The upper layer consists of elastic fibres, collagen fibres, fat deposits and blood vessels. It is connected posteriorly to the anterior face of the post-glenoid tubercle, the tympanic wall of the temporal bone, the cartilaginous meatus and the parotid gland lining. The lower layer, on the other hand, consists of a compact lamina of non-elastic collagen fibres, attached to the posterior surface of the condyle. Elastic fibres are one of the main constituents of the extracellular matrix of many connective tissues, and they are believed to play a very important role in the normal functions of many tissues such as blood vessels, lungs and dermis. The existence and functional importance of a fibroelastic tissue in the upper layer of the posterior portion of the articular disc has been described in human TMJ and in joints of many animal species. In human TMJ, it is believed that elastic fibres in the posterior and anterior attachment regions may play an important role in the repositioning of the disc during jaw closure. This study presents a review of the current literature on the morphology of elastic fibres in the posterior portion of the joint disc and the role attributed to them during all functions
Temporomandibular joint and related structures: anatomical and Histological aspects
No full textIn literature, there is no unanimous agreement about the anatomical and functional characteristics of the temporomandibular joint (TMJ) and its components. The aim of this work is to increase the knowledge about components of the temporomandibular joint, starting from the revision of classical anatomy, through macroscopic and microscopic study, 20 samples of human dissected temporomandibular joints
Anatomic relationship between temporomandibular joint and middle ear
No full textThe present study was designed to identify a relationship between temporomandibular joint and tympanic cavity and potentially justify the possible clinical correlations between these two anatomical entities. For this reason the authors conducted an anatomic-pathological study about the temporomandibular joint (TMJ) and the neighboring anatomical areas of the middle ear by autopsy finds of human adults

TMJ’s capsule histological and macroscopical study: Relationship between ligamentous laxity and TMJ dysfunctions
No full textIn this study, the authors examined the capsular structures of 20 human temporomandibular joints (TMJ) macroscopically and microscopically, in order to improve knowledge of these structures, as part of their possible participation in the genesis of TMJ dysfunctions
