缺牙区水平骨量不足一直是口腔种植的重要难题。骨劈开术是常用于解决此难题的手术方式之一,目前临床常用术式是采用超声骨刀沿牙槽嵴顶矢状劈开后,用骨凿将唇(颊)侧骨板向唇(颊)侧移位后增加牙槽骨水平宽度,达到同期种植的目的。骨劈开并同期植入种植体降低了困难病例的手术难度和风险,减少了患者就诊次数,降低患者成本。但若劈开后种植体周围的间隙大于1 mm或唇侧骨板分离,则需要同期进行植骨。但骨劈开术的使用也具有一定的适应症,要求缺牙区垂直骨高度足够,水平骨宽度不足(3～5 mm),骨质为Ⅲ ～ Ⅳ类骨,患者无种植手术的局部和全身禁忌证。近年来的研究表明骨劈开术具有创伤小、手术安全有效、不用开辟第二创口即可获得较好的骨增量效果等优点,一定程度上扩大了种植手术适应证。现本文对骨劈开术的翻瓣术式、非翻瓣术式及术后效果的进展进行综述。

The insufficient horizontal bone mass in the missing tooth area has always been an important problem of dental implant. Bone splitting is one of the surgical methods commonly used to solve this problem. At present, the commonly used surgical method is to use ultrasonic bone knife to sagittal splitting along the crest of the alveolar ridge, and then use bone chisel to shift the lateral bone plate of the lip (buccal) to the lip (buccal) to increase the horizontal width of the alveolar bone, so as to achieve the purpose of simultaneous implantation. Bone splitting and implantation of implants in the same period reduced the surgical difficulty and risk of difficult cases, reduced the number of patient visits, and reduced the cost of patients. However, if the gap around the implant was more than 1 mm or the labial bone plate was separated after splitting, bone grafting should be performed simultaneously. But the use of bone splitting technique also has a certain indications, demanding sufficient vertical bone height in the missing area, inadequate width of horizontal bone (3 mm to 5 mm), Ⅲ~Ⅳ class bone, without local and systemic contraindicated of planting surgery. In recent years, the research shows that bone splitting surgery has the advantages of small trauma, safe and effective operation, and better bone increment effect obtained without opening the second wound. This article reviewed the progress of flap operation, flapless operation and postoperative effect of bone splitting.
