【摘要】：目的对比块状珊瑚羟基磷灰石与自体骨块恢复下颌后牙区骨高度缺损的临床效果,探讨块状珊瑚羟基磷灰石通过楔入力固位的可行性。方法 37例下颌后牙缺失病例,A组19例,块状珊瑚羟基磷灰石通过箱状洞形楔入力固定;B组18例,自体骨块通过钛钉常规固位。植骨半年后行相应种植手术。在植骨前后、种植体植入时、二期手术、修复完成后的每年复诊,拍摄全景片并比较A、B两组骨高度的变化。结果 A、B两组均能有效恢复下颌骨的高度。以植骨后骨高度作为基准线,比较两组相应观察点骨高度的吸收值,A组均明显小于B组(P0.01)。结论 A、B两种方式均能有效地恢复下颌后牙区垂直高度,使用块状珊瑚羟基磷灰石通过箱状洞形的楔入固位恢复一定量的下颌骨高度缺损有良好的临床效果。
[Abstract]:Objective to compare the clinical effect of coralline hydroxyapatite and autogenous bone mass in the restoration of bone height defect in mandibular posterior teeth, and to explore the feasibility of retaining massive coral hydroxyapatite by wedging force. Methods A group of 19 patients with mandibular posterior tooth loss was treated with 37 cases of mandibular posterior tooth loss. There were 18 cases in group B with massive coral hydroxyapatite fixed with wedged force through box cavity. The autologous bone mass was routinely retained by titanium nail. Six months after bone grafting, the corresponding implant was performed. Before and after bone grafting, the second stage operation was performed when implants were implanted. Every year after repair, panoramic films were taken and the changes of bone height in group A were compared. Results the height of mandible was recovered effectively in group A and B, and the height of bone after bone graft was used as baseline. The absorption value of bone height in group A was significantly lower than that in group B (P 0.01). Conclusion the vertical height of mandibular posterior teeth can be recovered effectively by both methods of Agna B. Using massive coralline hydroxyapatite to restore a certain amount of mandibular height defect through box-shaped wedged retaining has good clinical effect.
