钛膜在上颌前牙区骨缺损延期即刻种植术中的临床应用观察

The clinical application observation of titanium membrane in the use of delayed immediate implant in anterior teeth region with bone defect

目的:通过钛膜在前牙区骨缺损的延期即刻种植术的应用,观察其成骨效果。方法:选取12例前牙区骨缺损病例,拔除患牙4～6周后,植入种植体,钛膜覆盖骨缺损区,6个月后二期手术观察成骨效果并完成冠修复。结果:共植入Frialit-2种植体16个,钛膜19片。2片钛膜术后2周发生部分暴露,予以再次缝合关闭创面。其余钛膜固位良好。术后6个月成骨效果满意。16个种植体均稳固,修复效果良好。结论:钛膜具有良好的引导骨再生作用,在前牙区骨缺损延期即刻种植中可发挥良好的成骨作用。

Objective： To observe the osteogenesis effect of titanium membrane in the use of delayed immediate implant in anterior teeth region. Method： 12 cases with bone defect in anterior teeth were selected. Dental implants were placed 4-6 weeks after teeth extraction. The bone defect was covered by titanium membrane simultaneously. Osteogenesis effect was observed and final restoration was made in secondary operation after 6 months. Result： 16 Frialit-2 implants and 19 titanium membranes were placed in the anterior of maxillary anterior region. 2 titanium membranes exposed partially in the oral cavity and the wound surfaces were closed by suture again. The other titanium membranes retained fine. Osteogenesis effect was satisfactory 6 months after primary operations. All the implants are stable and the restoration effect is satisfactory. Conclusion： The titanium membrane has excellent effect of guided bone regeneration and it plays a favorable osteogenesis effect in the use of delayed immediate implant in anterior teeth region.
