An open randomized controlled clinical trial to evaluate ridge preservation and repair using SocketKAP™ and SocketKAGE™: part 1‐three‐dimensional volumetric soft tissue analysis of study casts

Abstract Objectives The aims of this study were to evaluate (i) the efficacy of ridge preservation and repair involving Socket KAP ™ and Socket KAGE ™ devices following tooth removal; and (ii) ridge contour changes at 6 months post‐extraction in intact sockets and sockets with dehiscence defects. Material and methods Thirty‐six patients required a total of 61 teeth to be extracted. Five cohorts were established with groups A–C involving intact sockets and groups D and E involving facial dehiscence: (A) Negative Control; (B) Socket KAP ™ alone; (C) Anorganic Bovine Bone Mineral ( ABBM ) + Socket KAP ™ ; (D) Negative Control; and (E) ABBM + Socket KAP ™ + Socket KAGE ™ . Preoperative CBCT and laser‐scanned casts were obtained. Teeth segmented from preoperative CBCT were merged with study cast images to allow for digital removal of teeth from the casts. Volumetric measurements of ridge contour were performed. Images of preoperative and 6 months post‐operative casts were superimposed to measure ridge contour changes. Results Post‐extraction contour loss occurred in all sockets primarily in the crestal 3 mm but was also detected up to 6 mm from alveolar crest. For intact sockets, Socket KAP ™ or Socket KAP ™ + ABBM interventions led to greater percentages of remaining ridge contour when compared to controls. A significant difference favoring Socket KAP ™ + Socket KAGE ™ + ABBM treatment was observed for sockets with facial dehiscence when compared to controls. Conclusion Socket KAP ™ , with or without ABBM , significantly limited post‐extraction ridge contour loss in intact sockets. In the absence of a group treated with only the Socket KAGE ™ , it is not possible to determine its efficacy, although the combination of Socket KAGE ™ + Socket KAP ™ + ABBM was effective in limiting post‐extraction ridge contour loss in sockets with dehiscence defects.
