The first year of prosthetic loading is crucial to peri-implant bone levels; however, contributing factors are yet barely understood.
The purpose of the study is to investigate the influence of patient-, implant-, and prosthetic-related parameters on marginal bone resorption in partially edentulous patients within the first year of prosthetic loading.
This retrospective multifactorial analysis involved the following influencing factors: patient gender and age, implant diameter, implant location and neck design, insertion torque, insertion depth, splinted versus single-tooth restorations, crown height space, and crown-to-implant ratio.
Mean peri-implant bone resorption around 200 dental implants was 0.98 ± 0.76 mm and significantly correlated to higher implant insertion depth (p < .001), whereas no association to prosthetic parameters could be observed.
Within the limits of the present analysis, it can be concluded that apical implant positioning may constitute a relevant determinant of early peri-implant bone resorption.
种植体加载的第一年对种植体周围骨水平至关重要；然而，其影响因素仍鲜为人知。
本研究旨在调查患者、种植体和修复相关参数对部分牙列缺损患者在种植体加载第一年边缘骨吸收的影响。
这项回顾性多因素分析涉及以下影响因素：患者性别和年龄、种植体直径、种植体位置和颈部设计、植入扭矩、植入深度、联冠修复与单颗牙修复、冠高度间隙以及冠与种植体比例。
200颗牙种植体周围的平均种植体周围骨吸收为0.98±0.76mm，且与较高的种植体植入深度显著相关（p<0.001），而未观察到与修复参数的关联。
在本分析的范围内，可以得出结论，种植体根尖定位可能是早期种植体周围骨吸收的一个相关决定因素。
