Overview
Brief Summary
The purpose was to evaluate histomorphometrically the early healing at implants installed in sites prepared with either a sonic device or conventional drills.
Detailed Description
Sixteen volunteer patients will be recruited. Two titanium mini-implants will be installed in the distal segments of the maxilla in recipient sites prepared with either a sonic device or conventional drills. Biopsies containing the mini-implants will be retrieved after 2 weeks in eight patients, and after 6 weeks in the other eight patients. Histomorphometric analyses will be performed

Eligibility Criteria
Inclusion Criteria
- •presence of an edentulous atrophic zone in the posterior segment of the maxilla
- •height of the sinus floor ≥10 mm
- •≥ 25 years of age;
- •smoking ≤10 cigarettes per day
- •good general health

Outcomes
Primary Outcomes
New bone in contact with the implant surface
Time Frame: After 6 weeks, to evaluate the healing prior to load with a prosthesis
The percentages of new bone in contact with the implant surface will be evaluated in the histomorphometric analysis
Secondary Outcomes
- The percentage of total mineralized bone in contact with the implant surface.(After 6 weeks to evaluate the healing prior to load with a prosthesis)
