Under the conditions of this study, cast posts are preferable to restore endodontically treated teeth with flared canals and no ferrule.

Most removable partial denture (RPD) wearers are satisfied with their prostheses, but the factors that influence satisfaction and acceptance are still not determined.Objective:This study explored technical, biological, and satisfaction variables for the functioning of RPDs after five years, and compared the evaluation by the patient and by the clinician.Materials and Methods:Fifty adults (39 females, 11 males) were reexamined after five years of RPD service. Data were collected through clinical examination and a structured questionnaire to record the conditions of supporting soft tissues, prosthesis acceptance and technical characteristics, mastication, esthetics, comfort, hygiene, and need for professional intervention. Data were analyzed by descriptive statistics and Spearman correlation.Results:More than 50% of patients classified their RPDs as excellent regarding retention, mastication, esthetics, comfort, and hygiene. In the professional evaluation, retention and stability were considered excellent in more than 66% of cases, and hygiene of teeth and prostheses was considered good in 52% and 46%, respectively. The metallic framework and acrylic base were considered adapted in 92% of cases. Prosthesis acceptance was associated with retention, mastication, esthetics, hygiene, and comfort evaluated by the patient, and with retention, stability, and condition of the framework evaluated by the clinician. Retention and mastication/comfort evaluated by the patient had moderate positive correlation with retention and stability measured by the clinician. There was no association of hygiene evaluation by the patient and by the clinician.Conclusions:After five years, the oral rehabilitation with RPDs was satisfactory for most cases. There was correspondence between retention/retention and mastication-comfort/stability variables evaluated by the patient and by the clinician. Oral and prosthesis hygiene were not related.

Objetivo: Verificar a qualidade do material enviado pelos cirurgiões-dentistas aos laboratórios de prótese dentária; modelos de trabalho e planejamento para a confecção de próteses parciais removíveis. Materiais e Métodos: 20 (vinte) laboratórios da cidade de Porto Alegre/RS participaram do trabalho e 100 (cem) casos foram analisados. Os modelos enviados pelos dentistas foram examinados, fotografados e registrados. Os dados analisados foram: preparo dos dentes pilares, planejamento e condições técnicas. Resultados: Os resultados mostraram que o preparo de boca foi realizado em 28% dos casos e o desenho do planejamento foi enviado junto com o modelo em 35%. A área chapeável foi demarcada nos modelos em 3% dos casos e a descrição de montagem até 2° molar estava presente em 88%. O gesso utilizado no vazamento dos moldes correspondia a Gesso Tipo IV em 67% e 9% dos casos foram montados em Articulador Semi-Ajustável Conclusão: Os cirurgiões-dentistas continuam desconhecendo os princípios clínicos e técnicos da construção de próteses parciais removíveis, comprometendo a preservação das estruturas de suporte, e, conseqüentemente, a saúde oral dos pacientes.
