This retrospective clinical study aimed to evaluate the implants placed in fresh sockets and investigate the effect of varied oral health conditions and treatment plan details on the clinical and radiographic outcomes.
Fifty-nine participants (102 implants) were included in this study. Four variables, including mean probing depth (PD), mean marginal bone loss (MBL), pink esthetic score (PES), and patient satisfaction, were significant dependent variables, and the effects of independent variables on these four items were studied. The data were analyzed by the analysis of covariance (ANCOVA) using a statistical software.
The mean follow-up period was 4.75 ± 1.74 years, and the mean MBL was 1.21 ± 0.81 mm. The survival rate was 97 %. There were significant effects of the finish line site, keratinized gingival width, and attached gingival width on PD after adjusting the factors. Also, the implant brand, plaque index, and uncemented prosthesis affected MBL significantly. In addition, significant effects of the surgeon, implant brand, and proximal contact on PES were found.
More PD was found around restorations with a finish line site > 1.5 mm subgingival. Sufficient attached gingiva was a more effective factor on PD than keratinized gingiva. Implants with more plaque scores showed more MBL.
本回顾性临床研究旨在评估植入新鲜拔牙窝的种植体，并研究不同口腔健康状况和治疗计划细节对临床及影像学结果的影响。
本研究纳入了59名参与者（102颗种植体）。四个变量，包括平均探诊深度（PD）、平均边缘骨吸收（MBL）、粉色美学评分（PES）和患者满意度，为显著的因变量，并研究了自变量对这四个指标的影响。使用统计软件通过协方差分析（ANCOVA）对数据进行分析。
平均随访期为4.75±1.74年，平均MBL为1.21±0.81mm。生存率为97%。调整因素后，龈下边缘位置、角化龈宽度和附着龈宽度对PD有显著影响。此外，种植体品牌、菌斑指数和非粘结修复体对MBL有显著影响。另外，发现外科医生、种植体品牌和邻面接触对PES有显著影响。
在龈下边缘位置>1.5mm的修复体周围发现更多的PD。对于PD，充足的附着龈比角化龈是更有效的影响因素。菌斑评分较高的种植体显示出更多的MBL。
