Implant Survival in One-Stage Lateral versus Crestal Sinus Lift Procedures - A Systematic Review and Meta-Analysis


Objectives: The aim of this systematic review was to study the survival of dental implants placed in posterior maxilla with 4-8 mm residual bone height using one-stage lateral versus crestal sinus lifting approaches Methods/Statistical Analysis: Three electronic databases and hand searching were performed up to February 2016 for studies, comparing lateral versus crestal sinus lifting approaches. The scientific terms: “Crestal approach”, “Lateral approach”, “Internal Sinus Lift”, “External Sinus Lift”, “Sinus Floor Augmentation” and “Dental Implants” were used. Initially, title and abstract screening was performed for the retrieved articles followed by a full-text evaluation. Meta-analysis for implant survival was performed using RevMan 5.1 software. Findings: Screening of 1321 papers resulted in four eligible articles. The included retrospective cohort studies showed high risk whereas in RCT, the risk of bias was low. Meta-analysis revealed no differences in implant survival [RR = 1.01 (95% CI: 0.98-1.05)] between both approaches. Application/Improvements: The less invasive crestal approach can successfully replace the one-stage lateral approach in patients with 4-8 mm residual bone height.
