Abutment duplication – main task of modern age of development of prosthetic aspect of implantation. All research in the area of studying the nature of oral mucositis and periimplantitis is conflicting in its data. Hence, it is not possible to arrive at any conclusion as to what number of complications is related to the prosthetic stage of implantation.
At the same time there is no doubt that significant part of complications arises as a result of infection; the risk of infection is considerably increased in conditions of frequent extractions of healing caps or temporary abutments during clinical stages of implant restorations. These extractions are often accompanied by trauma, which results from damaging of a biological connection established between the titanium element of the suprastructure and the mucosa.
