Application of the tent bone augmentation technique in dental implants

Tent bone augmentation technology, including the tenting screw technique, autogenous cortical bone tenting technique and implant tent-pole technique, has recently been considered as a type of bone augmentation method to solve serious alveolar bone deficiency. The tenting screw technique is simple to perform and widely used in clinical practice; it can effectively increase bone in both horizontal and vertical directions in local bone defect areas with fewer complications than other techniques. The autogenous cortical bone tenting technique is mainly used for bone augmentation in large bone defect areas. The operation is relatively simple, but it needs to be combined with partial autogenous bone grafting, with high technical sensitivity and complications. The implant tent-pole technique is the most complex method and is mainly used for bone augmentation in severe alveolar ridge absorption areas of the mandible. The maximum vertical bone augmentation height can be obtained by combining this method with autogenous bone grafting, and the number of postoperative complications is relatively high. This article reviews recent research on the application of this technique to repair various alveolar bone defects in order to provide reference for clinical implant treatment.
