Title

Reduction of Crestal Bone Loss With Placement of Platform Switching Implant

Clinical Question

What is the effect of platform switching vs. platform matching implants in regard to crestal bone loss?

Clinical Bottom Line

The use of platform switching implants has been shown to minimize crestal bone loss when compared to platform matching implants.

Best Evidence

PubMed ID	Author / Year	Patient Group	Study type (level of evidence)
26723496	Santiago/2016	1098 patients in 25 studies (17 RCTs and 8 prospective studies) with total of 2266 implants.	Systematic review and meta-analysis
Key results	18 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))
24819807	Herekar/2014	15 studies (10 RCTs and 5 CCTs) with total of 1683 implants.	Study Type Systematic review and Meta-analysis
Key results	Marginal 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)”
26847169	Rocha/2016	63 patients with total of 135 implants.	Randomized Controlled Trial
Key results	From 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.

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.
