PubMed ID Author / Year Patient Group Study type
(level of evidence)
#1) 26723496Santiago/20161098 patients in 25 studies (17 RCTs and 8 prospective studies) with total of 2266 implants.Systematic review and meta-analysis
Key results18 out of 25 studies showed a statistically significant difference in favor of the use of platform switching implants for bone preservation. Meta-analysis, based on the full 25 study groups, showed a significant bone loss for the control group compared with the platform switching group.(MD −0.41 mm (95% CI −0.52 to −0.29, P < 0.00001))
#2) 24819807Herekar/201415 studies (10 RCTs and 5 CCTs) with total of 1683 implants.Study Type Systematic review and Meta-analysis
Key resultsMarginal bone loss around platform-switched implants was significantly less than platform-matched implants [MD]: -0.34; 95% confidence interval [CI]: -0.37 to -0.30; P < 0.00001)”
#3) 26847169Rocha/201663 patients with total of 135 implants.Randomized Controlled Trial
Key resultsFrom surgery to 36 months, the mean bone loss was 0.28 ± 0.56 mm for the platform-switching group and 0.68 ± 0.64 mm for the platform-matching group.
Evidence Search Platform switching implant AND marginal bone OR crestal bone.
Comments on
The Evidence
Validity: The best evidence on the platform switching implant included meta-analysis, systematic review, and RCTs. The validity of each study included in the meta-analysis and systematic review was assessed using the Jadad scale. They were classified on a scale of 0–5, with a score above 3 indicating an appropriate study.
Applicability Platform switching dental implant use is applicable for general, prosthodontic, periodontic dentists and oral surgeons. The evidence has shown its effectiveness in minimizing crestal bone loss.
