Abstract

BACKGROUND:

The partial edentulous posterior mandible is often a challenge area that requires a bone reconstructive surgery for implants placement.

PURPOSE:

This RCT was aimed to evaluate complications rate and vertical bone gain after Guided Bone Regeneration (GBR) with dense non-resorbable d-PTFE titanium-reinforced membranes (Group A) versus titanium meshes covered by cross-linked collagen membranes (Group B).

MATERIAL AND METHODS:

40 partially edentulous patients with atrophic posterior mandible, were randomly divided into two study group: 20 patients were treated with one stage GBR by means of non-resorbable d-PTFE titanium-reinforced membranes (Group A); and 20 patients, by means of titanium mesh covered by cross-linked collagen membranes (Group B). All complications were recorded, distinguishing between "surgical" and "healing" and between "minor" or "major.". Primary implants stability and vertical bone gain were also evaluated.

RESULTS:

In the group A, surgical and healing complication rates were 5.0% and 15.0%, respectively. In the group B, surgical and healing complication rates were 15.8% and 21.1%, respectively. No significant differences between two study group were observed regarding complications rate implant stability and vertical bone gain.

CONCLUSIONS:

Both GBR approaches for the restoration of atrophic posterior mandible achieved similar results regarding complications, vertical bone gain and implant stability.
