This prospective follow-up study aimed to evaluate the stability values of tapered titanium implants inserted into maxilla following ridge augmentation with free iliac bone graft and crestal bone changes up to three years of follow-up.
A total of seven patients with 34 tapered titanium implants in the maxilla with fixed protheses were enrolled in this prospective follow-up study. Patients with previously augmented maxillae using free iliac bone grafts were included. Implant stability was measured (Osstell™) for up to three months of healing. Peri-implant bone resorption was measured using radiographic images taken immediately after implant surgery and after three years. Using a clinical and radiological examination survival and success rates were evaluated.
After implant insertion, the stability was 60.93, whereas the stability increased significantly (P = 0.0192) to 64.97 at implant exposure (after 3 months). The mean bone loss around the implants was 1.13 mm after three years. Clinical parameters revealed a mean sulcus depth of 2.76 (1.18) mm and a bleeding on probing score of 0.29 (0.58). The survival rate was 100%, and the success rate was 67.65% at the end of the study.
Tapered implants can be used in free iliac bone grafts for fixed dentures. Implant stability values were high after insertion. In terms of a success rate of 67.65%, the patient's jaw reconstruction indicated a reduced implant success when comparing the data with healthy patients without any augmentation procedures.
本前瞻性随访研究旨在评估在游离髂骨移植进行牙槽嵴增高术后植入上颌的锥形钛种植体的稳定性值，以及随访长达三年的牙槽嵴顶骨变化情况。
本前瞻性随访研究共纳入7例上颌植入34枚带固定修复体的锥形钛种植体的患者。纳入此前使用游离髂骨移植进行上颌增高的患者。在长达三个月的愈合期内测量种植体稳定性（使用Osstell™）。使用种植体植入术后即刻及三年后的影像学图像测量种植体周围骨吸收情况。通过临床和影像学检查评估种植体的存留率和成功率。
种植体植入后，稳定性为60.93，而在种植体暴露时（3个月后）稳定性显著增加（P = 0.0192）至64.97。三年后种植体周围的平均骨吸收为1.13 mm。临床参数显示平均龈沟深度为2.76（1.18）mm，探诊出血评分为0.29（0.58）。研究结束时，存留率为100%，成功率为67.65%。
锥形种植体可用于游离髂骨移植以进行固定义齿修复。植入后种植体稳定性值较高。与未进行任何增高手术的健康患者的数据相比，患者颌骨重建的成功率为67.65%，表明种植体成功率有所降低。
