The aim of the present prospective clinical study is to compare the stability of the implant-bone interface by the ISQ quotient and marginal bone loss (MBL) rate during one year of follow-up in four system implants with the same surface and different design.
Prospective randomized clinical trial of 21 patients in which four implant systems with the same surface and different design were placed. Patients were treated by the same operator following a similar surgical protocol with submerged technique. The second surgery to perform the prosthesis was performed at 3 months. All patients went to their review at 6 months and a year. A periapical radiograph for crestal bone analysis and an Implant stability quotient by resonance frequency analysis (ISQ) analysis were taken at baseline and the reviews.
No statistically significant differences were found in the Implant stability quotient by resonance frequency analysis and Marginal Bone Loss in the four types of implants. The ISQ increased from the moment of insertion of the implant until the revision to the year, showing an increase of the stability implant, being this increasing less between the 6 months and the year.
Differences in the design of the four implants tested in this study did not show statistically significant differences in any of the variables studied, so the implant design does not influence implant stability and marginal bone loss in the first year after placement.
本前瞻性临床研究的目的是在随访一年期间，通过种植体稳定性商数（ISQ）和边缘骨丢失（MBL）率，比较四种具有相同表面和不同设计的种植系统的种植体-骨界面稳定性。
对21例患者进行前瞻性随机临床试验，植入四种具有相同表面和不同设计的种植系统。由同一名操作者按照类似的外科手术方案采用潜入式技术对患者进行治疗。在3个月时进行第二次手术以安装假体。所有患者在6个月和1年时进行复查。在基线和复查时拍摄根尖片以分析牙槽嵴顶骨情况，并通过共振频率分析（ISQ）分析种植体稳定性商数。
在四种类型的种植体中，通过共振频率分析得出的种植体稳定性商数和边缘骨丢失方面未发现统计学上的显著差异。从种植体植入到一年复查时，ISQ升高，表明种植体稳定性增加，在6个月至1年期间这种增加幅度较小。
本研究中测试的四种种植体设计差异在任何研究变量中均未显示出统计学上的显著差异，因此种植体设计在植入后的第一年不影响种植体稳定性和边缘骨丢失。
