PLATFORM SWITCHING: LITERATURE REVIEW
*Dr. Garima Singh, Dr. Chandan Kumar Kusum and Dr. Roma Goswami
The level of bone crest surrounding the implant is of utmost significance to determine osseointegrated implant success, as preservation of marginal bone height is highly important for long-term dental implant survival. Various approaches have been described in the literature to prevent the crestal bone loss, including platform switching. “PubMed” and “Google Scholar” were used to find out any studies involving platform switching concept from 1990 up to 2009. Crestal bone preservation should be thought of starting from the design of the implant to be placed. The technique to be followed in a given case will depend upon the density of bone, force factors by the patient, bone volume and amount of soft tissues, etc. The best possible method or the combination of the methods should be used to preserve the crestal bone for the long-term success of the implants.
Keywords: Crestal bone loss, crestal bone preservation, immediate implant placement, nonsubmerged implants, platform switching.
