【摘要】：目的:探讨临床上利用引导骨再生手术(Guided Bone Regeneration,GBR)、以及其相关的应用方式,使用在各种不同类型骨缺损的口腔种植手术中,来达到其重建的应用效果。为口腔种植手术中应用GBR技术提供临床依据。方法:研究对象为年龄33~60岁,男7例,女3例共10例患者。由不同因素导致牙缺失,欲使用种植牙修复的方式来进行重建。由于植牙区存在骨质缺损或骨量不足的因素应用引导骨再生术(GBR)进行骨质的增量,根据种植术式不同分为水平或垂直骨增量、上颌窦提升和即刻种植三种方式,其中水平或垂直骨增量4例、上颌窦开窗提升术3例、即刻种植骨增量3例,并同时或在骨愈合后植入种植体,修复时,通过术中或术后影像学观察骨增量的情况后酌情选择修复。结果:10例患者分别使用GBR进行骨增量手术,共植入15枚种植体,术后经6个月愈合期后,通过影像学和临床观察,骨增量区组织成骨良好,种植体与骨之间都呈现良好的骨结合。未出现骨吸收,种植体松动,牙龈红肿等情况。结论:1.GBR用于水平向或垂直向、上颌窦提升和即刻种植骨增量时的骨开窗、骨劈开都可以有稳定的成效。2.引导骨再生术能有效地对不同类型的骨缺损进行骨增量,解决骨组织不足的问题,符合种植美学要求。3.使用生物再生膜能有效阻止纤维细胞及上皮细胞长入骨缺损区并具有较好的骨生成效果。
[Abstract]:Objective: to explore the clinical application of guided Bone Regeneration (GBR) in different types of bone defects in oral implants.To provide clinical basis for the application of GBR technique in oral implant surgery.Methods: 10 patients, 7 males and 3 females, aged 3360 years were enrolled in the study.Tooth loss is caused by different factors. Implant restoration is used to reconstruct the tooth.Because of the existence of bone defect or insufficient bone mass in the dental implant area, the bone increment was carried out by guided bone regeneration (GBR). According to the different implant methods, there were three types of bone increment: horizontal or vertical bone increment, maxillary sinus lifting and immediate implantation.4 cases of horizontal or vertical bone increment, 3 cases of maxillary sinus fenestration and 3 cases of immediate implant bone increment.The bone increment was observed intraoperatively or postoperatively, and the repair was selected as appropriate.Results 15 implants were implanted with GBR in 10 patients. After 6 months of healing, the osteogenesis of bone increment zone was good through imaging and clinical observation.There is a good osseous bond between implant and bone.No bone resorption, implant loosening, gingival redness, etc.Conclusion: 1. GBR can be used in horizontal or vertical direction, maxillary sinus lifting and immediate implant bone increment to open the window, bone splitting can have a stable effect. 2.Guided bone regeneration can effectively increase the bone size of different types of bone defects and solve the problem of insufficient bone tissue, which meets the requirements of implant aesthetics.The application of biofilm can effectively prevent fibroblasts and epithelial cells from growing into the bone defect area and have a good effect on bone formation.
