BACKGROUND Platform switching for maintaining peri-implant bone levels has gained popularity among implant manufacturers over the last few years. However, the assumption that the inward shifting of the implant-abutment junction may preserve crestal bone was primarily based on serendipitous finding rather than scientific evidence. The objectives of the present study were to systematically review radiographic marginal bone-level changes and the survival of platform-switched implants compared to… 
It can be concluded that platform switching technique has signicant reduction in alveolar crestal bone level as compared to platform matched technique.
Influence of Platform Switching on Periimplant Bone Loss: A Systematic Review and Meta-analysis

The qualitative analysis depicts a trend favouring the platform-switching technique over platform- matching technique to prevent marginal bone loss, however, owing to the heterogeneity of the included studies, their results necessitate cautious interpretation.
Impact of platform switching on marginal peri-implant bone-level changes. A systematic review and meta-analysis
A meta-analysis revealed a significantly less mean MBL change at implants with a PS compared to PM-implant-abutment configuration, and a tendency favoring the PS technique to prevent or minimize peri-IMplant marginal bone loss compared with PM technique.
Value of platform switching on marginal peri-implant bone loss reduction : A summary review
The author recommend for further research to overcome all these previous limitations and for providing more evidence research on the eff ect of PS on MBL on the basis of existing and new evidence.
Peri-implant marginal bone level: a systematic review and meta-analysis of studies comparing platform switching versus conventionally restored implants.
PS technique appeared to be useful in limiting bone resorption around platform-switched dental implants, and data should be interpreted cautiously as significant heterogeneity and possible publication bias were noted.
The Impact of Platform-Switched Implants on the Marginal Bone Level and Soft Tissue Dimensions
It was observed that PSW implant systems obtain positive results in reducing the MBL and are more aesthetic in terms of soft tissue formation compared to PMI systems, and interest has been gradually increasing in the PSW system in recent years.
Does the platform switching implant affect the crestal bone level? A systematic review and meta-analysis
In patients restored with implant supported fixed restorations, there is insufficient evidence to support platform switching or platform matching implant-abutment connection design to improve implant survival and patient satisfaction.
Platform switching of implants may decrease bone loss
There is a significantly less MBL loss at implants with platform-switching than on implants withplatform-matching, according to a meta-analysis of 18 randomised clinical trials for the outcome MBL.
Implant platform switching concept: a literature review.
A literature review of studies which deal with the influence of platform-switched implants in hard and soft oral tissues indicates that peri-implant bone resorption is reduced with platform switching system.


Implant platform switching concept: an updated review.
It was shown that platform switching helps to prevent crestal bone loss after implant placement and helps obtain satisfactory aesthetic results.
Peri-implant bone level around implants with platform-switched abutments: preliminary data from a prospective study.
Evaluation of peri-implant bone loss around platform-switched implants.
Bone loss around two-piece implants that were restored according to the platform-switching protocol confirms the important role of the microgap between the implant and abutment in the remodeling of the peri-implant crestal bone.
Radiographic evaluation of marginal bone levels around platform-switched and non-platform-switched implants used in an immediate loading protocol.
The results of this study indicate that implants placed immediately in fresh extraction sockets and loaded immediately represent a predictable procedure, with no differences in bone level changes between "platform-switched" and conventional external-hexagon implants after 24 months.
Platform switching and marginal bone-level alterations: the results of a randomized-controlled trial.
Marginal bone levels were better maintained at implants restored according to the platform-switching concept and there was an inverse correlation between the extent of mismatching and the amount of bone loss.

The concept of platform switching is introduced and provides a foundation for future development of the biologic understanding of the observed radiographic findings and clinical rationale for this technique.
A prospective, randomized, controlled comparison of platform-switched and matched-abutment implants in short-span partial denture situations.
Findings suggest that less crestal bone loss occurs around a platform-switched dental implant versus a conventional implant.
Prospective study of 94 platform-switched implants observed from 1992 to 2006.
This is the longest follow-up to a prospective investigation of platform-switched implants and confirms the concept for preservation of crestal bone levels.
