摘　　要：目的评估翼上颌区种植体联合前部种植体修复后部萎缩的上颌无牙颌的短期临床效果及患者的满意度。方法回顾性研究筛选25例行前部和翼上颌区种植体支持的上颌固定修复并随访1年以上的上颌无牙颌患者作为研究对象,观察种植体存留率、种植体周软组织状态(包括探诊深度,改良龈沟出血指数,菌斑指数)、边缘骨吸收以及患者的满意度。结果前部和翼上颌区种植体的1年存留率分别为96.5%和97.8%(P>0.05)。2种种植体的探诊深度、改良龈沟出血指数、菌斑指数的差异均无统计学意义(P>0.05)。前部种植体的边缘骨吸收为0.62mm±0.44mm(近中)和0.61mm±0.40mm(远中),翼上颌区种植体的边缘骨吸收为0.64mm±0.46mm(近中)和0.68mm±0.41mm(远中),2种种植体近中、远中边缘骨吸收的差异均无统计学意义(P>0.05)。患者对前部与翼上颌区种植体支持的上颌全牙弓义齿具有较高的满意度。结论对于后部萎缩的上颌无牙颌,前部和翼上颌区种植体支持的全牙弓固定义齿具有可以接受的短期临床效果和较高的患者满意度,是一种可预测的和可行的修复方式。Objective This study aims to evaluate the short-term clinical outcomes and patient satisfaction of anterior and pterygoid implants in the rehabilitation of edentulous maxilla with posterior atrophy.Methods Given a minimum follow-up of 1 year,25 patients with fixed maxillary rehabilitation over anterior and pterygoid implants were enrolled in this retrospective study.The implant survival rates,peri-implant soft tissue status(including probing depth,modified sulcus bleeding index,and plaque index),marginal bone loss,and patient satisfaction were measured.Results The survival rates for anterior and pterygoid implants at 1-year follow-up were 96.5%and 97.8%,respectively(P>0.05).No statistically significant difference in probing depth,modified sulcus bleeding index,and plaque index was observed between the two types of implants(P>0.05).The marginal bone losses of anterior implants were 0.62 mm±0.44 mm(mesial)and 0.61 mm±0.40 mm(distal),and those of pterygoid implants were 0.64 mm±0.46 mm(mesial)and 0.68 mm±0.41 mm(distal)mm.These results showed no statistical difference in mesial and distal sites(P>0.05).Patients indicated a high degree of satisfaction with the full-arch prostheses supported by anterior and pterygoid implants.Conclusion For the edentulous maxilla with posterior atrophy,full-arch fixed prostheses supported by anterior and pterygoid implants has an acceptable short-term clinical outcome and excellent patient satisfaction.It may be considered as a predictable and feasible method for maxillary rehabilitation.
