Rialzo del seno mascellare con prelievo di osso autologo da siti intraorali: chirurgia piezoelettrica vs chirurgia tradizionale

Objectives

The primary aim of this research was to evaluate the success of bone regeneration achieved with maxillary sinus lifting performed with two different techniques; the secondary aim was to evaluate the outcome of dental implants inserted in the new bone.

Materials and methods

In this study, 10 patients were treated with bilateral sinus lifts performed with autologous bone grafts taken from intraoral sites. Two different techniques were used on each patient: piezoelectric surgery for right-side interventions (group A) and traditional instruments with osteotrites for left-sided interventions (group B). Four to five months after the reconstructive surgery, 40 implants were positioned in the regenerated bone.

Results

Radiographic and clinical assessments of the grafts revealed increases in new bone and increases in height (h) amounting to 3.71 millimeters (49%) in group A and 3.26 millimeters (43%) in group B. Five-year cumulative implant survival rates were 95.46% in group A and 94% in group B.

Conclusions

The results of this study indicate that piezoelectric and traditional techniques for maxillary sinus lifts with intraoral grafts are both effective. The piezoelectric approach is better tolerated, less stressful for the bone tissue, and produces more predictable outcomes than the more invasive procedure with osteotrites.
