Summary

When an implant is placed, it is assumed that there will be a loss of bone in the more coronal area around it. The placement of the implant in relation to bone level, either crestal or subcrestal and the type of connection chosen, either external connection or internal connection, have been related as one of the factors that caused this loss. The preservation of the peri-implant bone influences the shape and contour of the underlying soft tissues, which are important for the aesthetic result of the treatment and for the success of the same.

Hypothesis: The hypothesis is that there are no differences between the external and internal connection with regard to marginal bone loss. In implants placed at the crestal and subcrestal level, the hypothesis is that there is greater marginal bone loss in implants placed at the subcrestal level.

Objectives: Main: To evaluate the marginal bone loss around implants of internal connection and external connection. Secondary: To compare the loss of bone in implants of internal connection placed at crestal and subcrestal level. To evaluate intra and post-operative complications.

Material and methods: A prospective and randomized radiological study will be performed. 150 implants will be placed in patients who must present partial edentulism and require the replacement of at least 2 crowns on implants in the same jaw. In a randomized manner, implants of external connection and internal connection will be placed. Other features such as surface treatment type of the implant will be similar in both types of implants to reduce bias.

With this study the investigators will try to define if there is a procedure in when to the connection of the implant and the location of this, that is more beneficial with respect to the preservation of bone.
