Morphological features of peri-implant tissue after placement of dental implants into the extraction socket

In experiments on pigs, bone regeneration was studied after implantation of implants with four cylindrical roots and support cone and laminar crest-shaped implants with shape memory effect. The implants were placed to the extraction socket (mandibular canine) and through the socket immediately after tooth extraction using osteoplastic material or without using collapan-L. The use of collapan-L accelerated regeneration of peri-implant tissue and provided stable fixation of dental construct in the bone over 3 months after surgery, which can be relevant for determining timing of prosthodontic therapy and constructional features of prosthesis.
