Comparison of the use of piezosurgery expander and conventional instruments on primary implant stability
1Department of Oral and Maxillofacial Surgery, Okan University, Faculty of Dentistry, Istanbul, Turkey.
Objective:
To compare the use of a piezosurgery expander and conventional chisel/osteotome on primary implant stability.
Materials And Methods:
Twenty fresh ribs were divided into two main groups; group P and group C. In group P, bone expansion was performed using piezosurgery. In group C, bone expansion was performed using conventional chisel osteotomy. In both groups, the implants were inserted into the ribs after bone expansion. After implant placement, primary stability values were evaluated from the bucco-lingual (B-L) and mesio-distal (M-D) sides of the implant.
Results:
The primary stability values on the B-L side of both implants in group P were significantly higher than in group C (P < 0.05).
Conclusion:
The use of piezo-expanders in the alveolar split technique has better effects on primary implant stability compared with the conventional technique.
