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.
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.
The survival rates for anterior and pterygoid implants at 1-year follow-up were 96.5% and 97.8%, respectively (>0.05). No statistically significant difference in probing depth, modified sulcus bleeding index, and plaque index was observed between the two types of implants (>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 (>0.05). Patients indicated a high degree of satisfaction with the full-arch prostheses supported by anterior and pterygoid implants.
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.
本研究旨在评估在后部牙槽嵴萎缩的无牙上颌中，使用前牙区和翼突区种植体进行修复的短期临床效果和患者满意度。
本回顾性研究共纳入 25 例接受前牙区和翼突区种植体固定上颌修复的患者，随访时间至少 1 年。测量种植体的存活率、种植体周围软组织状况（包括探诊深度、改良龈沟出血指数和菌斑指数）、边缘骨吸收情况和患者满意度。
在 1 年随访时，前牙区和翼突区种植体的存活率分别为 96.5%和 97.8%（>0.05）。两种种植体在探诊深度、改良龈沟出血指数和菌斑指数方面无统计学差异（>0.05）。前牙种植体的边缘骨吸收量为 0.62mm±0.44mm（近中）和 0.61mm±0.40mm（远中），翼突区种植体的边缘骨吸收量为 0.64mm±0.46mm（近中）和 0.68mm±0.41mm（远中），近中和远中位点的差异无统计学意义（>0.05）。患者对前牙区和翼突区种植体支持的全口义齿表示高度满意。
对于后部牙槽嵴萎缩的无牙上颌，使用前牙区和翼突区种植体支持的全口固定义齿具有可接受的短期临床效果和良好的患者满意度。它可能是一种可预测且可行的上颌修复方法。
