Clinical, Radiological and Microbiological Outcomes of Implants With Two Different Connection Configurations, a Split-mouth RCT.

This study designed as a randomized controlled split-mouth trial will be conducted at the Dental Clinic of the University of Valencia. The aim will be to assess differences in clinical, radiological and microbiological outcomes between implants with 2 different connections: internal hexagon and conical connection. Following the premises, to minimize the bias related to prosthetic phase and maximize the effect of connections on MBL changes, a 1abutment-1time protocol will be used. The study hypothesis is that there will be no statistically significant differences between both implant connections.
