Guided bone regeneration for implant placement using absorbable collagen membranes: case presentations.
The current research on the application of guided tissue regeneration principles is focused on the use of absorbable matrix barriers in bone augmentation procedures in extraction sites and around implants. This paper presents two cases in which a new absorbable collagen membrane is used for guided bone regeneration. In the first case, freeze-dried demineralized bone was used with the membrane to place an implant in a fresh extraction site with a grave osseous defect. In the second case, the collagen membrane provided the augmentation of a narrow ridge where three implants were placed, without the use of allograft. In both cases, the barrier membrane demonstrated its applicability for bone regeneration with only one surgical procedure, without complications. The learning objective of this article is to update the knowledge of absorbable barrier membranes from the clinical experience of the authors.
