Objective: This study aims to evaluate the clinical effect of oral repair membrane and β-tricalcium phosphate (β-TCP) on the treatment of jaw cyst.
Methods: A retrospective analysis was performed on 81 cases of jaw cysts, and clinical data were collected for the comparison of traditional surgical curettage (group A, 27 cases), biofilm covering bone wounds after curettage (group B, 27 cases), and β-TCP filling combined with biofilm covering.
Results: No recurrence occurred in 81 patients, and no significant difference in preoperative CT value among the three groups (P<0.05). Follow-up CT reexamination 3, 6, and 12 months after operation showed significant differences among the three groups of CT values (P<0.05). Group C was better than Group B or Group A (P<0.05).
Conclusions: In traditional jaw cyst curettage, the application of biofilm exhibited good osteogenesis effect, and the combined application of β-TCP and biofilm exerted a better effect.
目的 探讨口腔修复膜和β-磷酸三钙（β-TCP）在颌骨囊肿术后骨缺损修复中的临床效果。方法 对81例颌骨囊肿病例进行回顾性分析，收集临床资料，比较传统手术刮治（A组，27例）、刮治后放置修复膜覆盖创面（B组，27例）和刮治后放置骨粉充填骨缺损并覆盖修复膜（C组，27例）3种治疗方式的疗效。结果 81例患者术后均无复发。3组患者术前CT值差异无统计学意义（P<0.05）；术后3、6、12个月复查CT，3组CT值间差异具有统计学意义（P<0.05），C组优于B组和A组（P<0.05）。结论 相对于传统的颌骨囊肿刮治疗法，应用修复膜具有较好的成骨效果，联合应用β-TCP和修复膜可获得更佳的疗效。.
