A large (19 mm x 24 mm) periapical lesion associated with tooth #10, perforating both the labial and palatal cortical plates, was treated with decalcified freeze-dried bone allograft and guided bone regeneration. The membranes were removed after a seven-month healing period. Complete osseous reconstruction of the cortical plates was noted. Biopsies demonstrated healing with mature bone and hemopoietic marrow. Few particles of decalcified freeze-dried bone could be observed. Graft particles that remained were surrounded by new bone. The learning objective of this article is to present the regeneration procedure utilized along with the histologic biopsy results to the clinician.
一颗与10号牙相关的大型（19毫米×24毫米）根尖周病变，已穿破唇侧和腭侧皮质骨板，采用脱钙冻干骨移植和引导骨再生进行治疗。七个月的愈合期后取出膜。观察到皮质骨板完全骨重建。活检显示有成熟骨和造血骨髓愈合。仅观察到少量脱钙冻干骨颗粒。残留的移植颗粒被新骨包围。本文的学习目标是向临床医生展示所采用的再生程序以及组织学活检结果。
