Brief summary

multi center study with randomized controlled trial design, split mouth

Detailed description

The present study has been designed as a multicenter prospective randomized controlled trial design. Fifteen clinical centers will treat patients by inserting and immediately loading implants with two different surgical protocols. Each patient will receive two identical implants: after randomization, the test site will be prepared by ultrasonic microvibrations and the control site using twist drills. Both implants will be loaded with a provisional crown within 48 hours after surgery. For each inserted implant, collection of experimental parameters will be required up to 2 years after surgery.

Inclusion criteria

indications for two implant-supported single crowns with immediate loading in the upper or lower arch (in the incisor, canine or premolar area), based on accurate diagnosis and treatment planning; 2) implants can be in the same or in different quadrants; 3) implant sites must be performed in similar bone quality (i.e. both maxillary or mandibular); 4) the bone crest must be healed (at least three months elapsed after tooth loss); 5) presence of a residual bone crest with an adequate volume to allow the insertion of a 3.8x11.5 mm implant without any kind of regenerative procedure; 6) age of the patient \>18 years; 7) patient willing and fully capable to comply with the study protocol; 8) written informed consent given;
