简要总结
The objective of the present study is to evaluate if loss of multiple adjacent teeth will cause proportionally greater tissue diminution than the loss of single teeth the possibility of counteracting unfavourable ridge modeling after multiple tooth extractions by placing implants in the fresh extraction sites soft tissue alterations at implants and adjacent teeth
详细描述
The study will be designed as a prospective, randomized, controlled multicenter study evaluating the potential of endosseous implants (OsseospeedTM,EV, Astra Tech System, DentsplyTM, Mölndal, Sweden) placed in fresh extraction sockets to preserve the ridge dimensions at the edentulous site.
Three centers will be involved in the study namely, (i) Department of Periodontology, University of Padova, Italy, (ii) Institute Franci, Padova, Italy, (iii) Department of Periodontology, Sahlgrenska Academy, University of Gothenburg, Sweden.
Prior to the start of the study the human review board at the treatment centers must approve the study protocol as well as the informed consent forms.
Group assignment
Following the removal of the target teeth, the subject (site) will be randomly assigned to one of 2 groups:
