The objective of this work is to assess the possible association between the crownimplant ratio (C/I) of the implant-supported restorations and the peri-implant crestal bone loss. After reviewing 1,064 implants placed in 416 patients –including those in the different articles consulted- the different variables were analysed that may influence the peri-implant bone loss (crown-implant ratio and the relation between them). No association was found between these variables, except in one of the studies, in which an inversely proportional relation was established between the C/I proportion and the peri-implant bone loss. The C/I ratio per se is not associated to bone loss (biological complications); however, some authors have demonstrated that it may generate certain mechanical complications. Therefore, there are other variables (design of the implant, insertion level, occlusal load), that would be related to the bone loss. We suggest including these variables in future studies, since we consider that they may contribute to long-term bone remodelling.
