Abstract
Objectives: The aims of this study were (i) to evaluate the efficacy of ridge preservation and repair procedures involving the application of SocketKAP (TM) and SocketKAGE (TM) devices following tooth removal and (ii) to evaluate alveolar bone volumetric changes at 6 months post-extraction in intact sockets or those with facial wall dehiscence defects using 3-dimensional pre- and postoperative CBCT data.
Materials and Methods: Thirty-six patients required 61 teeth extracted. Five cohorts were established: Group A: Intact Socket Negative Control Group B: Intact Socket SocketKAP (TM) Group C: Intact Socket Filled with Anorganic Bovine Bone Mineral (ABBM) + SocketKAP (TM) Group D: Facial Dehiscence Socket Negative Control Group E: Facial Dehiscence Socket Filled with ABBM + SocketKAP (TM) + SocketKAGET (TM). Preoperative CBCT scans were obtained followed by digital subtraction of the test teeth. At 6 months post-extraction, another CBCT scan was obtained. The pre- and postoperative scans were then superimposed, allowing highly accurate quantitative determination of the 3D volumetric alveolar bone volume changes from baseline through 6 months.
Results: Significant volumetric bone loss occurred in all sockets, localized mainly in the 0 3 mm zone apical to the ridge crest. For intact sockets, SocketKAP (TM) + ABBM treatment led to a statistically significant greater percentage of remaining mineralized tissue volume when compared to negative control group. A significant difference favoring SocketKAPT (TM) + SocketKAGE (TM) + ABBM treatment was observed for sockets with facial dehiscence defects compared to the negative control group.
Conclusions: SocketKAP (TM) with ABBM, appears effective in limiting post-extraction volumetric bone loss in intact sockets, while SocketKAP (TM) + SocketKAGE + ABBM appears effective in limiting post-extraction bone loss in sockets with dehiscence defects.
