THE IMPACT OF DOUBLE LAYER MEMBRANE TECHNIQUE ON BONE REGENERATION IN POSTEXTRACTION ALVEOLI–A PATHOHISTOLOGICAL EXPERIMENTAL STUDY IN DOGS

The use of equine derived and enzymatically deantigenated membrane to assess the efficacy of one layer vs double layer technique in dogs

This study wanted to assess if one layer vs double layer membrane to cover the grafting site in post-extractive socket may have a different efficacy profile. The experiments were conducted in six dogs. Each dog received the extraction of 4 teeths per side in the lower-jaw. Three post extractive alveoli were filled with bone substitute of equine origin and then covered with: collagen bioresorbable membrane of porcine origin; collagen bioresorbable membrane of equine origin; pericardial bioresorbable membrane of equine origin. After healing period, biopsies were taken and analysed histologically.  Results show that resorbable membranes placed in two layers resulted in a higher degree of bone regeneration compared to those where resorbable membranes were placed in one layer.
