Abstract:
Background: Implant-abutment junction is one of the factorswhich may cause peri-implant bone loss. Due to particulari-ties of flapless approach, it is necessary to establish optimalrelation between the bone crest and implant-abutment junc-tion.Aim: To establish the influence of two-stage dental implantplatform position upon crestal bone during healing period incase of one-step flapless placement.
