RESUMEN
Este trabalho relata um caso clínico de reabilitação protética dental em um paciente edêntulo total superior com prótese fixa tipo protocolo sobre seis implantes, porém modificada com o acréscimo de uma gengiva destacável e retida por encaixes de semiprecisão. Esta alternativa reabilitadora fornece ao paciente a funcionalidade e o conforto dos dentes fixos, bem como mantém a estética facial pelo apoio do lábio, mantém fonação adequada e possibilita correta higiene peri-implantar e da prótese, através de gengiva destacável retida por encaixes. Concluímos que as reabilitações fixas maxilares sobre implantes do tipo protocolo, modificadas pelo acréscimo de uma gengiva destacável, são uma ótima alternativa para os casos de severa atrofia vestibular do rebordo alveolar da maxila...
This study reports a clinical case of prosthetic rehabilitation of a patient with a totally edentulous maxilla using a fixed prosthesis supported by six implants, but modified by the inclusion of a removable gingival veneer retained with attachments. This alternative provides a rehabilitation model as functional and comfortable as the fixed prosthesis, enhancing facial aesthetics (reestablishing lip support) and phonetics and facilitating patient access for proper periimplant hygiene and prosthesis cleaning. We concluded that implant-supported fixed maxillary restorations, modified by the inclusion of a removable gingival veneer, come as a great alternative in cases of severe maxillary alveolar ridge atrophy...

The objective of this study was to determine the reproducibility of a positioning device and a method for measuring the area of alveolar bone loss (ABL) in hemi mandibles of mice. Mucoperiosteal flaps were raised in CF1 Mus domesticus mice (n = 10) on the buccal aspects of the left side of the mandibles. Twenty-one days after surgery, the animals were sacrificed, and the mandibles were resected and stained with 1% toluidine blue. Two positioning devices, one for the buccal and the other for lingual aspect, were fabricated to keep the hemi mandibles in a standard position. The reliabilities of the positioning device and the method for measuring ABL area were analyzed using two series of pictures. The photographs were digitized and ABL measured as the exposed root area. Measurements were performed by two blinded examiners using image analysis software. Intra- and inter-examiner reproducibility of the positioning method ranged from -1.5 to +1.33 mm, while intra- and inter-examiner reproducibility of the measurement technique ranged from -3.37 to 14.70. Our results indicate that, due to the small variation observed in ABL area assessment, the positioning device and method for measuring ABL area represent useful techniques for evaluating ABL in mice.
