COMPLICATION RATE OF OSTEOCONDUCTIVE MEMBRANES OVER FRESH ALVEOLAR SOCKETS

What is it about?

Introduction:The aim of the study was to assess the clinical efficacy of the osteoconductive bioresorbable membranes “Collapan” and “Collost” used for the preservation of the alveolar process and to compare it with the natural bone healing of an alveolar socket.Materials and methods:The 67 patients observed were divided into 3 groups. The first group included 20 individuals who were treated by covering the alveolus with the “Collapan” membrane. Group 2 included 22 patients in whom the “Collost” membrane was used. The third group (control) consisted of 25 patients in whom the alveolus was not covered with any membrane over the natural blood clot. The clinical efficacy of the membranes was based on the number of complications in the postoperative period. Also, the level of alveolar bone reduction was measured using residual height and width as parameters.Results:In the postoperative period, 6 (9%) complications of an infectious-inflammatory nature were detected in group 1, 2 (3%) - in group 2, 19 (28%) - in group 3. The use of the “Collost” yielded the best result in preserving alveolar height and width. Conclusion:The results of this pilot study showed that it is appropriate to use the osteoplastic bioresorbable “Collost” and “Collapan” membranes due to the low incidence of complications and the favourable effect on preserving bone volume.Keywords:dentoalveolar surgery, alveolar socket preservation, osteoconductive membranes
