摘　　要：上颌中切牙区普遍存在剩余牙槽骨不足或切牙管过度膨大的情况,钛种植体侵入切牙管可能影响种植体的稳定性,并发生一系列并发症,如鼻腭管囊肿、术后短期感觉障碍、种植体失败等。为解决这一临床问题,本研究对骨增量材料在切牙管种植中的应用进行探索与实践。本文对各类不同的骨增量材料在切牙管种植中的应用进行文献回顾及分析,结合1例骨增量材料用于切牙管种植的临床病例,展示了骨增量材料在切牙管内引导骨再生后植入种植体的临床效果。种植体骨结合良好,患者修复效果满意。戴牙6个月后复查,种植体周软组织稳定,无明显骨吸收。利用骨增量材料引导切牙管内成骨,为后期种植体植入提供三维骨支撑,有助于获得良好的种植体稳定性和前牙美学效果。据文献报道,不同的骨增量材料,如自体骨,同种异体骨、混合骨代用品,或自体骨混合骨代用品都可实现切牙管内成骨。Due to the prevalence of insufficient remaining alveolar bone or excessive expansion of the incisive canal in the maxillary central incisor region,the stability of implants may be affected.Titanium implants into incisor canals may cause a series of complications such as nasopalatine canal cyst,postoperative short-term sensory disturbance,implant failure,and so on.In order to solve this clinical problem,this study explored and practiced the application of bone substitutes in the incisive canal for implant placement.The application of various bone substitutes in the incisive canal for implant placement was reviewed and analyzed in this paper.Combined with a clinical case of bone substitutes used in the incisive canal for implant placement,the clinical effect of bone substitutes in the incisive canal for guided bone regeneration and implant placement was demonstrated.The implant osseointegration was good and the aesthetic outcome was satisfactory.Re-examination after 6 months showed that the soft tissue around the implant was stable and there was no obvious bone resorption.The use of bone substitutes to guide the internal osteogenesis of the incisive canal can provide three-dimensional bone support for the implant,which is helpful in obtaining good implant stability and anterior aesthetic effect.It has been reported in the literature that different materials,such as autogenous bone,allograft bone or mixed bone substitute,or autogenous bone mixed bone substitute,can achieve the internal osteogenesis of the incisive canal.
