Summary

The aim of this study is to compare two pre-prosthetic surgical techniques for augmentation of vertical mandibular ridge defects in preparation for implant placement, the first using customized ceramic membranes and the second using tenting titanium screws in conjunction with particulate bone graft and collagen membrane (modified sausage technique).

Description

Background: Expansion of the periosteum and soft tissue matrix by tenting has been described as a method of Guided Bone Regeneration (GBR) for reconstruction of atrophic alveolar ridges.

Materials and Methods: The current study is a prospective controlled clinical trial, conducted on 14 patients, having about 7 mm of vertical bone height in the posterior mandible above the inferior alveolar canal. They are divided into 2 equal groups, each consisting of 7 patients. The first group receives customized ceramic membranes with a vertical height 5 mm above the crest of the ridge to tent out the soft tissue matrix, while in the second group, tenting of the soft tissue is done by fixation of two tenting screws, particulate bone graft is packed then covered by collagen membrane that is fixed by bone tacks (modified sausage technique).
