[Clinical aspects of therapeutic options in oral rehabilitation of partially edentulous patients]. / Aspecte clinice ale terapiei edentatiei partial intinse la cazurile sociale.

UNLABELLED: This study aims at identifying practical ways of approaching social cases, and creating a hierarchy of the final functions of restauration. MATERIAL AND METHOD: In 2008 the Clinical Base for Learning from the School of Dental Medicine, Iasi, recorded for the Partially Stretched Edentation Clinic and Therapy course a prevalence of biterminal partial edentation (Class I Kennedy)-66.39 per cent from the total number of patients, followed by uniterminal edentation (Class II Kennedy), having 40.24 per cent of the clinical cases, whereas INTERCALATE edentation (Class III Kennedy), frontal edentation (Class IV Kennedy), and subtotal edentation have about 20.12.1 per cent each. RESULTS: The clinical form of edentation contributes to the election of a proper therapeutic solution as well as the odonto-parodontal and muco-osseous status of each clinical case, the patient's general condition or the socio economic and technical factors leading to a modern, classical or social prothesing. An important aspect to take into account is the large percentage of social cases diagnosed with partially edentation, pleading for provisional protheses with an established role in therapy, which sometimes may become social prothesing--an outstanding clinical reality. Social cases should be solved with a view to restoring functionality such as lower level redimensioning and cranio-mandibulary repositioning, whereas aesthetic requirements fall into therapies based on metallo-ceramic and hybrid prothesing or implanto-prothetic therapy.

[The role of the polimers in increased acrylic biomaterials qualities used in prosthetic restaurations]. / Rolul polimerilor in optimizarea biomaterialelor acrilice utilizate in restaurarile protetice.

UNLABELLED: This study is aimed at the improvement of the biomaterials used in the field of entirely removable prosthesis quality. One important aspect taken into consideration is the adhering of the Candida albicans fibres, a bacterium frequently met at the oral cavity level of old patients, to different variations of acrylate, in search of ways of counter-attacking this tendency of a very resistant microbian structure. MATERIAL AND METHODS: A number of 19 test-tubes were made under the shape of thin, rectangular plates, 40 mm long and 20 mm wide and a depth varying from 1.8 to 2.5. RESULTS: After analysing the test-tubes for traction forces, was observed: The beraking of the base material was followed by the taking over of the force by the metallic net: the small (elastic) distortions of the acrylate were not simultaneous with the distortions of the reinforcement materials. Polyethylene fibres are made by twisted threads and it presents a lower elasticity module compared tot hat of the acrylic resin, especially duet o the ondulation of the fibres. CONCLUSIONS: Among the advantages of the use acrylic bases renforcement with polyetilene fibres we notice its lower interface effect in comparison with the net acrylical reinforcement.
