The aim of this study was to analyze the survival of dental implants installed in maxillae reconstructed with autogenous iliac crest grafts and to assess patient satisfaction with the treatment by means of a questionnaire. The study conducted medical record reviews and clinical/radiographic assessments of 10 patients with severe maxillary atrophy who had undergone reconstruction with autogenous iliac crest grafts and rehabilitation with dental implants between 2008 and 2011. Patients were assessed for the survival of the implants, considering implant diameter and length, smoking status, diagnosis of diabetes, type of loss, and region of implant loss. In addition, a questionnaire with specific questions on the patients' satisfaction with the treatment was administered. Seventy-six implants were installed in the sampled patients, and only 1 loss was observed (late loss in the anterior maxilla region) after an average follow-up of 7.9 years, which corresponds to a 98.60% survival rate. The installed implants were of the most frequently used dimension (3.75 × 10 mm). One sampled patient was diabetic, and a second patient was both diabetic and a smoker. No loss of implants was observed in these 2 patients. All patients reported being completely satisfied with the treatment and would undergo the procedure again or refer it to a friend/relative. Six patients reported regular maintenance of the prosthesis, and only 3 had changed the prosthesis prior to the time of questionnaire administration. The results of this limited study with a restricted sample population suggest that the reconstruction of the maxilla with an autogenous iliac crest graft provides both adequate implant survival and patient satisfaction.
本研究的目的是分析在采用自体髂嵴移植重建的上颌骨中植入牙种植体的存留情况，并通过问卷调查评估患者对该治疗的满意度。该研究对2008年至2011年间10例严重上颌骨萎缩患者的病历进行了回顾，并对其进行了临床/影像学评估，这些患者均接受了自体髂嵴移植重建及牙种植体修复。根据种植体直径和长度、吸烟状况、糖尿病诊断、缺失类型以及种植体缺失部位，对患者的种植体存留情况进行评估。此外，还发放了一份关于患者对治疗满意度的特定问题问卷。在抽样患者中总共植入了76枚种植体，平均随访7.9年后，仅观察到1枚种植体脱落（上颌前部区域的晚期脱落），存留率为98.60%。所植入的种植体为最常用的尺寸（3.75×10毫米）。抽样患者中有1例患有糖尿病，另1例既患有糖尿病又是吸烟者。这2例患者均未出现种植体脱落。所有患者均表示对治疗完全满意，愿意再次接受该治疗或推荐给朋友/亲属。6例患者报告对义齿进行了定期维护，只有3例在问卷调查时更换过义齿。这项样本量有限的研究结果表明，采用自体髂嵴移植重建上颌骨可实现足够的种植体存留率并使患者满意。
