目的:对于严重萎缩性上颌骨患者的口腔康复,传统的牙种植体是成功的替代方法;然而,需要进一步研究单侧骨种植体的使用,以验证其疗效.本研究旨在评估单侧zy骨植入物在上颌骨极度萎缩和/或先前植入物失败的部分无牙患者的口腔康复中的放置。
方法:这项回顾性临床研究包括上颌骨部分无牙的患者,这些患者接受了单侧zy骨植入。主要结果是植入物存活。术中,术后和假体并发症也根据患者的临床记录进行评估.
结果:本研究共纳入了32例患者(34个骨种植体),平均年龄为60.45±8.74岁(范围47至78岁)。平均随访时间为34.3±25.5个月,植入物的总存活率为100%。无任何患者发生术中或术后并发症,无假体失效或并发症记录.
结论:结果表明,对于严重萎缩性骨和/或先前种植失败的上颌骨部分缺失的患者,单侧骨种植体插入用于口腔康复可以被认为是使用与先进的植骨手术相关的传统牙种植体的成功替代方法。
OBJECTIVE: Zygomatic implants are successful alternatives to conventional dental implants for oral rehabilitation of patients with severely atrophic maxillae; however, the use of unilateral zygomatic implants needs to be studied further to validate their efficacy. The present investigation aimed to evaluate unilateral zygomatic implant placement in the oral rehabilitation of partially edentulous patients with extremely atrophic maxillary bone and/or previous implant failures.
METHODS: This retrospective clinical study included patients with partially edentulous maxillae who underwent unilateral zygomatic implant insertion. The primary outcome was implant survival. Intraoperative, postoperative and prosthetic complications were also assessed based on patients\' clinical records.
RESULTS: A total of 32 patients (34 zygomatic implants) with a mean age of 60.45 ± 8.74 years (range 47 to 78 years) were included in the study. The mean follow-up period was 34.3 ± 25.5 months, and the overall implant survival rate was 100%. No intraoperative or postoperative complications developed in any of the patients, and no prosthesis failures or complications were recorded.
CONCLUSIONS: The results indicate that unilateral zygomatic implant insertion for oral rehabilitation of patients with partially edentulous posterior maxillae with severely atrophic bone and/or previous implant failures can be considered a successful alternative to use of conventional dental implants associated with advanced bone grafting procedures.
