下颌后牙区水平骨缺损分类、增量术式与临床决策OA

Horizontal alveolar bone resorption is common following tooth loss in the posterior mandible.Selecting an appropriate bone augmentation strategy is key to ensuring the long-term success of implant restoration.This article innovatively proposes a defect morphology-based classification system,categorizing bone defects into potential,favorable,partially favorable,and unfavorable types by analyzing the spatial relationship between the implant position and the outer alveolar ridge contour of adjacent teeth.This classification helps assess the spatial maintenance capacity of the defect site.Based on this classification,the article systematically outlines the corresponding implant timing and augmentation technique selection for different defect categories,establishing a clear clinical decision-making pathway to provide a reference for the implant restoration workflow in the posterior mandible.
