Statement of problem
Few investigations concerning the use of pterygoid implants have reported reproducible and consistent data, making survival data controversial.
Purpose
The purpose of this clinical study was to investigate the 1-year survival and success rates of pterygoid implants and prostheses in participants affected by severe atrophy of the posterior maxilla requiring a complete-arch immediate fixed prosthesis.
Material and methods
Fifteen participants, either completely edentulous or with failing dentition in the maxillary arch and with severe atrophy of the posterior maxilla, were enrolled in the study. All participants underwent prosthodontic rehabilitation after implant placement in both the anterior maxilla areas and the pterygoid regions. The survival data of the implants were evaluated at the time of abutment connection by means of a mobility test for each implant. After placement of the prostheses, survival was assessed by means of marginal bone maintenance as assessed by panoramic radiographs and the absence of pain or symptoms of infection. The t test was used for evaluating the difference in age between men and women (α=.05). Correlations between categorical variables (Fisher exact test) were used to evaluate the possible association between the number of implants and both the age and presence of comorbidities (α=.05).
Results
During the 1-year follow-up, high prosthesis stability and no implant loss were observed for all participants. In addition, participants did not report any pain or paresthesia. No peri-implant radiolucency was detected in the panoramic radiographs. Survival and success rates in the follow-up period were 100%.
Conclusions
The present study supports the conclusion that pterygoid implants have a high success rate with minimal or no complications.

翼状骨种植体支持的立即固定康复治疗严重上颌骨萎缩的参与者:一项前瞻性队列研究的 1 年负荷后结果
问题陈述
很少有关于使用翼状骨植入物的调查报告了可重复和一致的数据,这使得生存数据存在争议。
目的
本临床研究的目的是调查因上颌后部严重萎缩而需要完整牙弓即刻固定假体的参与者的翼状骨植入物和假体的 1 年生存率和成功率。
材料与方法
该研究招募了 15 名参与者,他们要么完全无牙要么上颌弓牙列缺失以及上颌后部严重萎缩。所有参与者在前上颌骨区域和翼状骨区域植入种植体后都接受了修复修复。在基台连接时通过对每个种植体的活动度测试评估种植体的存活数据。放置假体后,通过全景 X 光片评估的边缘骨维护和无疼痛或感染症状来评估存活率。该Ť测试用于评估男性和女性之间的年龄差异(α = .05)。分类变量之间的相关性(Fisher 精确检验)用于评估植入物数量与年龄和合并症存在之间的可能关联 (α=.05)。
结果
在 1 年的随访期间,所有参与者均观察到高假体稳定性和无种植体丢失。此外,参与者没有报告任何疼痛或感觉异常。在全景射线照片中没有检测到种植体周围的射线可透性。随访期间的存活率和成功率为 100%。
结论
目前的研究支持这样的结论,即翼状骨植入物具有很高的成功率,并发症很少或没有并发症。
