Bone Healing at Implants Installed in Sites Prepared Either With a Sonic Device or Drills

Bone Healing at Implants Installed in Sites Prepared Either With a Sonic Device or Drills. A Split-mouth Histomorphometric Randomized Controlled Trial

The purpose was to evaluate histomorphometrically the early healing at implants installed in sites prepared with either a sonic device or conventional drills.

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

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
• no contraindication for oral surgical procedures
• not being pregnant.

Exclusion Criteria:

• presence of systemic disorders
• chemotherapy or radiotherapy
• smokers >10 cigarettes per day
• previous bone augmentation procedures in the same region.
