【摘要】 在下颌前牙美学区，通常垂直向骨量充足而唇舌水平向骨量不足。本文介绍一例慢性牙周炎导致多颗下颌切牙待拔除的患者，在下颌前牙区拔牙即刻应用牙槽嵴骨劈开技术并行同期种植的病例。该病例拔牙同期行骨劈开并植入种植体，术后6个月行二期手术，并在一期手术后7个月和8个月，通过数字化技术分别完成临时修复和永久修复。结果显示拔牙即刻种植同期行骨劈开有效地增加了水平骨量，提高了种植成功率，减少了手术次数，避免了开辟第二术区，结合文献分析认为掌握好适应证和操作细节，相比于其他种植方案具有一定的优势。更多还原

【Abstract】 In the anterior mandibular aesthetic area, there is usually sufficient bone in the vertical direction and insufficient bone in the buccolingual and horizontal direction. In this paper, we present a case of a patient with multiple mandibular incisors to be extracted due to chronic periodontitis, in which the ridge splitting was applied to the anterior mandibular alveolar ridge with teeth extraction and immediate implant placement simultaneously. Teeth extraction, ridge splitting and implant placement were performed at the same time, and the second surgery was performed 6 months after the operation, and temporary restoration and permanent restoration were completed by digital technology 7 and 8 months after the first surgery.Teeth extraction and immediate implant placement with ridge splitting procedure allows the clinician to effectively augment the horizontal bone, improve implant success rate, reduce the number of operations and avoid a second operative area. The simultaneous application of ridge splitting technique with tooth extraction and implant placement with proper indications and operation details may have certain advantages over other implant options.更多还原
