ABSTRACT

Guided bone regeneration has had a significant impact in the solution of secondary bone deficiencies produced by tooth losing. These bone regeneration techniques have enhanced the possibility of placement of implants, expanding the scope for their selection and location, particularly in patients with partial edentulism. Bone regeneration for horizontal defects through a graft (autologous, allograft or xenograft) and an absorbable collagen membrane can be considered as a predictable procedure. Currently, bone volume gain is not the only objective pursued; preservation and reconstruction of soft tissues (gingiva-papilla) are additionally intended. Furthermore, the prosthetic works should not only benefit of these advantages, but should sculpt, support and preserve them. The objective of this clinical report is to demonstrate how periodontal and prosthetic efforts could be properly combined for protection and mutual benefit, achieving appropriate appearance and functionality.
