Soft Tissue and Marginal Bone Adaptation on Platform-Switched Implants with a Morse Cone Connection: A Histomorphometric Study in Dogs
Bolle, Caroline / Gustin, Marie-Paule / Fau, Didier / Boivin, Georges / Exbrayat, Patrick / Grosgogeat, Brigitte
The purpose of this study was to investigate peri-implant tissue adaptation on platform-switched implants with a Morse cone-type connection, after 3 and 12 weeks of healing in dogs. Ten weeks after mandibular premolar extractions, eight beagle dogs received three implants each. At each biopsy interval, four animals were sacrificed and biopsies were processed for histologic analysis. The height of the peri-implant mucosa was 2.32 mm and 2.88 mm, respectively, whereas the bone level in relation to the implant platform was −0.39 mm and −0.67 mm, respectively, after 3 and 12 weeks of healing. Within the limits of the present study, platform-switched implants exhibited reduced values of biologic width and marginal bone loss when compared with previous data.
