Oskarsson M, et al. - Researchers compared the peri-implant tissue response to subcrestal or crestal placement of implants with or without “platform-switched” implant/abutment connections. During the full 20 weeks of observation, findings suggested an occurrence of bone remodeling within the early healing phase. Significantly less crestal bone loss was demonstrated by PS-implants compared to PM-implants. At subcrestally placed implants, the peri-implant mucosa was thicker vs a crestal placement.
