Remontagem das próteses totais em articulador utilizando os dispositivos zanetti para realização do ajuste oclusal / Remountig total prostheses in articulator by using Zanetti device for oclusal adjustment

Após os procedimentos laboratoriais de processamento das bases das próteses totais, faz-se necessário a realização do ajuste oclusal para a obtenção de uma oclusão balanceada, que visa à harmonização das novas próteses com o sistema estomatognático, gerando melhora da estabilidade e retenção, com conseqüente aumento do conforto do paciente. Pela dificuldade de se fazer o ajuste oclusal diretamente na boca, o presente trabalho visa a descrever uma técnica de remontagem clínica das próteses totais em articulador semi-ajustável, utilizando os dispositivos Zanetti, permitindo melhor visualização dos contatos oclusais e maior precisão para a realização do ajuste aclusal, tanto em cêntrica, quanto - e principalmente- nos movimentos excêntricos

Analysis of the condyle/fossa relationship before and after prosthetic rehabilitation with maxillary complete denture and mandibular removable partial denture.

STATEMENT OF PROBLEM: The influence of the loss of posterior teeth on the condylar position and on temporomandibular disorders (TMDs) remains a controversial issue. PURPOSE: This study investigated whether prosthetic rehabilitation promoted modification of the condylar position in subjects without symptoms of TMDs. MATERIAL AND METHODS: The temporomandibular joints (TMJs) of 12 women (age 37 to 74), all with existing maxillary complete dentures but no removable partial denture (RPD) restoring the Kennedy class I partially edentulous mandibular arch and no clinical signs of TMDs according to the criteria established by Helkimo, were viewed in maximal intercuspal position with corrected lateral tomography before and after prosthetic rehabilitation with a new maxillary complete denture and a mandibular RPD. Before prosthetic rehabilitation, a mandibular stabilizing base was fabricated to prevent the existing maxillary complete denture from dislodging during tomographic examination. Two methods were used to evaluate tomograms: (1) linear measurements of the subjective narrowest anterior and posterior intra-articular joint spaces made from the tomograms by use of a digital caliper and (2) linear measurements of the anterior and posterior intra-articular joint spaces on the basis of drawings and tracings. Repeated-measures analysis of variance followed by orthogonal contrasts were used to evaluate differences between measurements carried out on the same subject under the different test conditions of the study (before prosthetic rehabilitation, before prosthetic rehabilitation with a mandibular stabilizing base in position, and after prosthetic rehabilitation) (P<.05). RESULTS: Before prosthetic rehabilitation, a predominance of posterior condylar positions was observed. Before prosthetic rehabilitation with a mandibular stabilizing base in position, a significant decrease was observed in posterior condylar positions (P=.03). This decrease was more marked after prosthetic rehabilitation (P=.02). The subjective evaluation and comparison on the basis of drawings and tracings used to analyze the tomograms produced similar results (P=.70). CONCLUSION: Within the limitations of this study, significant changes in the condylar position occurred after prosthetic rehabilitation in subjects without symptoms of TMDs.

Overdentures; carga precoce e magnetos: relato de caso clínico / Overdentures; immediate loading and magnets: case report

Normalmente, na região interforames de mandíbulas edentadas, encontra-se tecido ósseo suficiente para a colocação de implantes que irão auxiliar na retenção e estabilidade de próteses totais. Com o intuito de devolver a função, a estética e a fonética, em um menor período de tempo, este trabalho clínico descreve a reabilitação bucal de um paciente totalmente edentado com a colocação de implantes de único tempo cirúrgico (carga precoce), prótese total superior e prótese total inferior com retenção magnética
