The aim of this retrospective study was to evaluate the long-term predictability of treatment using implants with hydrophobic and hydrophilic surfaces, according to clinical parameters and survival rates. Records from all patients who received dental implants between January 2013 and December 2014 at ILAPEO College were fully evaluated by two graduate dentists. Records with incomplete or unclear data were excluded from the study. The variables evaluated were demographic data, design of implants and prosthetic components, type of loading, data related to the patients' general health, and survival of implants and prostheses. The final retrospective sample comprised 776 patients with 2707 implants, with up to 5 years of follow-up. Survival rates of implants and prostheses were 97.93% and 98.77%, respectively. Implants with hydrophobic (97.87%) and hydrophilic (98.34%) surfaces exhibited similar survival rates. Considering the different types of loading, there was no statistically significant difference between loading protocols regarding implant survival rates. Unsuitable healing capacity, uncooperative and not motivated patient, loss of prosthesis, and peri-implant bone loss were confirmed statistically to be factors that may contribute to implant loss, according to hazard ratio and odds ratio. The present study showed similar and high overall survival rates for implant with both types of surfaces, in the long term. The surface treatment, implant model and loading protocol had no significant influence on implant loss. Therefore, the evaluated implant systems were able to offer a high predictability for both hydrophobic and hydrophilic implants.
本回顾性研究的目的是根据临床参数和存活率评估使用亲水和疏水性表面的种植体治疗的长期预测性。通过两位研究生牙医对 2013 年 1 月至 2014 年 12 月期间在 ILAPEO 学院接受牙科种植体的所有患者的记录进行了全面评估。记录中存在不完整或不明确数据的患者被排除在研究之外。评估的变量包括人口统计学数据、种植体和修复体组件的设计、加载类型、患者一般健康状况的数据以及种植体和修复体的存活率。最终的回顾性样本包括 776 名患者的 2707 个种植体，随访时间长达 5 年。种植体和修复体的存活率分别为 97.93%和 98.77%。具有疏水性（97.87%）和亲水性（98.34%）表面的种植体具有相似的存活率。考虑到不同类型的加载，在种植体存活率方面，加载方案之间没有统计学上的显著差异。根据危害比和优势比，确认愈合能力不足、不合作和不积极的患者、修复体丢失和种植体周围骨丢失是导致种植体丢失的因素。本研究显示，在长期内，两种类型表面的种植体总体存活率相似且较高。表面处理、种植体模型和加载方案对种植体丢失没有显著影响。因此，评估的种植体系统能够为亲水和疏水性种植体提供高的预测性。
