Objective : To evaluate the treatment plan , clinical outcome and related problems in patients with congenital missing teeth. Methods: From November 2000 to February 2009, thirty seven patients with congenital missing teeth underwent thorough diagnostic workup, treatment planning and an interdisciplinary approach to ensure optimal treatment in Department of Implant Dentistry, Peking University, School and Hospital of Stomatology. A standard follow-up protocol was conducted for all the patients. Results: The enrolled cases in this study were classified in to 3 types: single tooth missing, multiple teeth missing and edentulous. Among them single tooth missing was found in 21 cases, multiple teeth missing was found in 12 cases and 4 cases were edentulous. 120 implants were placed and restored in 37 patients with the mean follow-up 39. 3 months ( 10 - 109 months) after prosthetic functioning. Two implants lost after function about 6 months and the remaining implants functioned well until the last review. No adverse complications such as pain and nerve trauma was observed and the mean bone resorption was 1. 91 mm. Conclusion: An interdisciplinary approach ensures optimal treatment for patients with congenital missing teeth. Implant restorations provide an alternative way with predictable clinical results.%目的:探讨先天缺牙患者种植修复存在的问题、对策,评估其临床效果.方法:对2000年11月至2009年2月37例在北京大学口腔医院种植中心就诊的先天缺牙患者进行检查、诊断,制定治疗方案,进行涉及多个学科(主要包括正畸科、止颌外科、种植科)的系统治疗并最终完成种植修复.所有患者均按照北京大学口腔医院种植中心复查程序进行追踪随访.结果:本研究纳入的病例分为3类:先天单牙缺失、先天多牙缺失、先天多牙缺失继发无牙颌,其中单牙缺失21例,多牙缺失12例,多牙缺失继发上颌和/或下颌牙列缺失4例(上颌2个,下颌2个).37名先天缺牙患者接受了种植修复,共植入120个种植体,种植修复后平均追踪39.3(10～109)个月.截止至最后1次复查共2个种植体在修复后半年脱落,其余种植体行使功能良好,未见疼痛、神经损伤等并发症,X线检查种植体颈部骨吸收平均1.91 mm .结论:先天缺牙患者一般需经多学科协作序列治疗,方可进行种植修复,能较大程度地改善患者的咀嚼、发音及容貌,提高患者生活质量,近期临床效果满意.
