目的
对20例在骨结合期诊断为种植体根尖周病变的患者进行回顾性分析，评价种植体根尖周手术的治疗效果。
材料和方法
对1996年至2010年期间接受种植体根尖周手术的所有患者进行了回顾性病历审查。诊断种植体根尖周病变并进行相应的种植体根尖周手术的标准是：（1）骨结合期间的急性疼痛（种植体植入后8周）位于受影响种植体区域或存在与种植体顶端相关的粘液瘘;（2）种植体缺乏活动性;（3）非浸没种植体的非钝叩诊;和（4）种植体根尖周射线可透性的存在或不存在。
结果
20名患者（13名女性和7名男性）的22个种植体被诊断为根尖周病变，平均年龄为54.3岁（范围：32 - 70岁），并通过手术入路进行了连续治疗。在19个种植体中，根据症状和影像学体征诊断为急性根尖种植体周围炎（7例未化脓，12例化脓），3例根据瘘管的存在诊断为亚急性根尖种植体周围炎。在至少1年的随访后，20个种植体保持功能，没有临床或放射学改变;治疗种植体的存活率为91%。
结论
在骨整合阶段早期诊断种植体根尖周炎性病变，并及时进行手术治疗，使治疗后的种植体存活率达到91%。
PURPOSE
To report 20 cases with implant periapical pathology diagnosed during the osseointegration phase, evaluating retrospectively the efficacy of the treatment with implant periapical surgery.
MATERIALS AND METHODS
A retrospective chart review was conducted of all patients in whom implant periapical surgery was performed between 1996 and 2010. The criteria for diagnosing implant periapical pathology and, accordingly, performing implant periapical surgery were: (1) acute pain during the osseointegration period (8 weeks after implant placement) located in the area of the affected implant or presence of mucous fistula in relation with the implant apex; (2) absence of implant mobility; (3) non-dull percussion of nonsubmerged implants; and (4) presence or absence of implant periapical radiolucency.
RESULTS
Twenty-two implants were diagnosed with periapical pathology in 20 patients (13 women and 7 men) with a mean age of 54.3 years (range, 32 to 70 years) and were consecutively treated by a surgical approach. In 19 implants, the diagnosis was acute apical peri-implantitis (nonsuppurated in 7 cases and suppurated in 12), as based on the symptoms and radiographic sign, and in 3 cases it was subacute apical peri-implantitis, as based on the presence of a fistula. After a minimum follow-up of 1 year, 20 implants remained functional, with no clinical or radiologic alterations; the survival rate of the treated implants was 91%.
CONCLUSION
The early diagnosis of inflammatory implant periapical lesions during the osseintegration phase, and their prompt surgical treatment, led to a survival rate of the treated implants of 91%.
