Diagnosis and treatment planning are key factors in achieving successful outcomes after placing and restoring implants placed immediately after tooth extraction. The efficacy of immediate implant placement has been established and shown to be predictable if reasonable guidelines are followed. Some or all of the following suggestions, depending on individual circumstances, should be considered when evaluating a patient for dental implants: thorough medical and dental histories, clinical photographs, study casts, periapical and panogram radiographs as well as a linear tomography or computerised tomography of the proposed implant sites. Reasons for tooth extraction include but are not limited to: insufficient crown to root ratios, remaining root length, periodontal attachment levels, periodontal health of teeth adjacent to the proposed implant sites, unrestorable caries, root fractures with large endodontic posts, root resorption, teeth with deep furcation invasions being considered as abutments for fixed partial dentures and questionable teeth in need of endodontic retreatment.
诊断和治疗计划是拔牙后即刻植入和修复种植体取得成功结果的关键因素。即刻种植的有效性已经得到证实，并且如果遵循合理的指导原则，其效果是可预测的。在评估患者是否适合种植牙时，应根据个体情况考虑以下部分或全部建议：全面的医学和牙科病史、临床照片、研究模型、根尖片和全景片，以及拟植入部位的线性断层扫描或计算机断层扫描。拔牙的原因包括但不限于：冠根比例不足、剩余牙根长度、牙周附着水平、拟植入部位相邻牙齿的牙周健康状况、无法修复的龋齿、带有大型根管桩的根折、牙根吸收、被视为固定局部义齿基牙的深根分叉侵入牙齿，以及需要进行根管再治疗的可疑牙齿。
