Does platform switching allow closer implant placement?

METHODS:
Marginal bone levels and tissue quality was evaluated after 2 months of healing for 72 implant sites in 12 pig mandibles. The interimplant distance was either 2 mm or 3 mm.

RESULTS:
No difference was seen when the interimplant distance was 2 mm or 3 mm in terms of interproximal bone loss.

CONCLUSIONS:
Platform switched implants have a reduced amount of crestal bone loss. The horizontal displacement of the implant-abutment junction may allow adjacent platform-switched implants to be placed as close as 2 mm apart without losing the height of intercrestal bone. This should positively affect the preservation of the interdental papilla.
