尽管角状（骨内）缺损的缺损形态通常是根据限制缺损的骨壁来描述的，但对缺损形态的更生物学描述应包括牙周膜的视角，因为牙周治疗的最高目标是牙周组织的再生，包括除了用牙槽骨填充缺损之外，还包括新的牙骨质附着和插入的牙周膜纤维。不同形态的骨内牙周缺损可能具有不同的再生潜力，这取决于牙周组织细胞来源的程度。本报告主要涉及骨内缺损的愈合，骨内缺损至少有两个骨壁，最好是三个骨壁或两个骨壁的组合。虽然单壁骨内缺损的特征在于在缺损的顶端部分中仅一个有限的区域用于牙周韧带细胞增殖，但由至少两个骨壁邻接的角状缺损也产生牙周韧带细胞增殖的侧向来源，因此可以以比单壁骨内缺损更可预测的方式愈合。
Although defect morphology of angular (intrabony) defects is generally described according to the osseous walls limiting the defect, a more biological description of the defect morphology should include the perspective of the periodontal ligament, since the highest goal of periodontal therapy is the regeneration of the periodontium including new cementum apposition with inserting periodontal ligament fibers in addition to the filling of defects with alveolar bone. Intraosseous periodontal defects of varying morphology may have a varying regenerative potential depending on the extent of the source of the cells from the periodontium. This report is mainly concerned with the healing of intraosseous defects limited by at least two, and preferably three bony walls or combinations of the two. While one-wall intraosseous defects are characterized by only one limited area for periodontal ligament cell proliferation in the apical portion of the defect, angular defects bordered by at least two bony walls also yield lateral sources for periodontal ligament cell proliferation and hence may heal in a more predictable way than one-wall intrabony defects.
