摘要
AimThe aim of this study was to evaluate the efficacy of ridge preservation involving novel devices used for obturation of socket orifice (Socket cap; SocketKAP) and resorbable cage used for space maintenance in sites with facial wall dehiscence (Socket cage; SocketKAGE). @@@ Material and MethodsEight teeth were extracted in each of six Macaca fascicularis non-human primates. Six intervention groups consisted of the following: Group A: intact socket negative control. Group B: intact socket: socket cap. Group C: intact socket filled with anorganic bovine bone mineral (ABBM) + socket cap. Group D: dehiscence: negative control. Group E: dehiscence: socket cap + socket cage. Group F: dehiscence: filled with ABBM + socket cap + socket cage. CBCT scans were obtained preoperatively and at 6 and 12weeks following intervention. The pre- and postoperative scans were superimposed, to quantify 3D volumetric alveolar bone changes. @@@ ResultsVolumetric bone loss occurred in all sockets, not only within the cretal zone (0-3mm) to the ridge crest, as has been commonly reported by other investigators, but significant bone loss was also detected in the zone which was 3-6mm apical to the alveolar crest. For intact sockets, socket cap + ABBM led to significantly greater percentages of remaining bone volume when compared to groups A and B. A significant difference favoring socket cap + socket cage + ABBM treatment was observed for sockets with facial dehiscence defects compared to groups D and E. @@@ ConclusionsSocket cap in conjunction with ABBM appears effective in limiting post-extraction volumetric bone loss in intact sockets, while socket cap + socket cage + ABBM appears effective in limiting post-extraction bone loss in sockets with dehiscence defects.
