摘　　要：通过对1例牙槽嵴宽度不足患者尝试采用改良骨劈开技术进行牙槽嵴宽度骨增量及牙种植手术,探讨骨劈开牙槽骨增宽技术的改良方法.手术方式：通过手术在牙槽骨宽度不足区域沿牙槽嵴顶和唇、颊侧周围呈方块状切透骨皮质;第4周行第2次骨劈开种植手术,轻微翻起舌侧瓣,尽量保护唇侧黏骨膜附着,沿牙槽嵴顶原切骨线行骨劈开、分离,将由之形成的唇侧黏骨膜骨瓣推向唇侧后常规植入种植体.种植体之间填入人工骨粉和（或）自体骨,胶原膜和富血小板纤维蛋白膜覆盖伤口缝合.手术完全保持了（唇）颊侧劈开的骨皮质血供,种植体之间填入人工骨粉和（或）自体骨位于内外骨板之间,直接与骨松质接触,骨生长和成骨效果良好.种植手术中应用牙槽骨黏骨膜骨瓣可有效保留牙槽骨唇颊侧骨板厚度,避免唇侧骨板吸收.To introduce a method of increasing the width of alveolar bone.The patient,who needed dental implantation and had narrow alveolar bone,was selected.The preparation of mucosa-periosteal bone flap included two surgeries.The first surgery was corticotomy,which made a square cortex cut on narrow alveolar bone region.The second surgery was performed four weeks after the first one,which split the alveolar bone and inserted implants.Artificial bone and/or autologous bone was filled between inner and outer bone plate,and collagen membrane and platelet-rich fibrin membrane were used to cover the wound.This technique maintained the blood supply of labial（buccal） alveolar bone completely.Artificial bone and/ or autologous bone graft contacted with cancellous bone directly and led to better bone growth and bone formation.Alveolar bone mucosa-periosteal bone flap can maintain the labial（buccal） alveolar bone effectively and avoid bone resorption.
