Abstract
The purpose of this article is to describe, step by step, the technique of Guided Bone Regeneration (GBR) for vertical ridge augmentation in extremely atrophic maxillary crests. In order to achieve this in a patient with significant bone deficit in the fourth quadrant, vertical bone augmentation was carried out using titanium-reinforced dense polytetrafluoroethylene (d-PTFE) membranes, as well as autogenous bone in combination with inorganic bovine bone in a 1:1 proportion. After nine months, significant vertical bone gain was formed. Measurements were taken both before and after surgery, which allowed for quantifying the results with an increase of 10 mm horizontally and 4 mm vertically. Three implants were placed on the ridge with newly formed bone and after one year of load, the new bone remained stable. This clinical case corroborates the effectiveness of the Guided Bone Regeneration technique. Two years after surgery, the high success rate of the implants placed after this surgical procedure allows us to affirm the efficacy of this technique for the rehabilitation of atrophic alveolar crests without showing relevant complications.
