This study aims to assess the impact of two implant surfaces, SLA and SLActive, on implant stability, measured by ISQ levels over a 12-week period.
A comprehensive search of MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, and Dentistry and Oral Sciences databases for randomized controlled trials (RCTs) up to February 2023 was conducted. The inclusion criteria were studies involving adult patients treated with SLA and SLActive implants, with assessment of implant stability through ISQ levels up to 12 weeks post-placement.
From the initial 180 potentially eligible publications identified, six RCTs were included in our analysis, comprising 326 implants (50.6% SLA and 49.4% SLActive). Three studies were classified as low risk, while three had an unclear risk of bias. Overall, SLActive implants demonstrated comparable stability levels, as measured by ISQ, to SLA implants within the 12-week interval for implants placed in the maxillary or mandibular region. However, findings from the RCTs suggest that the SLActive surface led to an earlier transition point, a faster return to stability levels, and higher ISQ values at the end of 12 weeks compared to the SLA surface for implants placed in the palatal region.
SLActive surfaces exhibited stability levels similar to SLA surfaces for maxillary and mandibular implants. Notably, for palatal implants, SLActive resulted in a quicker transition point and higher stability levels at the 12-week mark. Due to the limited number of trials and potential study heterogeneity, further research is needed to validate these findings.
本研究旨在评估两种种植体表面（SLA和SLActive）对种植体稳定性的影响，通过在12周内测量种植体稳定性商（ISQ）水平来评估。
对MEDLINE、EMBASE、Cochrane对照试验中央注册库以及牙科和口腔科学数据库进行全面检索，以查找截至2023年2月的随机对照试验（RCT）。纳入标准为涉及接受SLA和SLActive种植体治疗的成年患者的研究，且通过植入后长达12周的ISQ水平评估种植体稳定性。
从最初识别出的180篇潜在合格出版物中，6项RCT被纳入我们的分析，共326颗种植体（50.6%为SLA，49.4%为SLActive）。3项研究被归类为低风险，而3项研究的偏倚风险不明确。总体而言，对于上颌或下颌区域植入的种植体，在12周间隔内，通过ISQ测量，SLActive种植体的稳定性水平与SLA种植体相当。然而，RCT的结果表明，与SLA表面相比，对于腭部植入的种植体，SLActive表面导致更早的转变点、更快恢复到稳定水平，并且在12周结束时ISQ值更高。
SLActive表面在上颌和下颌种植体中表现出与SLA表面相似的稳定性水平。值得注意的是，对于腭部种植体，SLActive在12周时导致更快的转变点和更高的稳定性水平。由于试验数量有限和潜在的研究异质性，需要进一步研究来验证这些发现。
