Marginal bone resorption of posterior mandible dental implants with different insertion methods

Area of Science:

• Dental Implantology
• Oral Surgery
• Biomaterials Science

Background:

• Marginal bone loss is a key indicator of dental implant success.
• Comparing insertion techniques is crucial for optimizing long-term implant stability.

Purpose of the Study:

• To evaluate and compare marginal bone loss around dental implants using manual versus mechanized insertion methods.
• To determine the long-term effects of different insertion techniques on peri-implant bone levels.

Main Methods:

• A comparative study involving 273 patients divided into manual and mechanized implant insertion groups.
• Standardized peri-apical radiographs were taken post-surgery, at three months, and at six months.
• An independent t-test was used to analyze differences in marginal bone loss between the groups.

Main Results:

• No significant difference in marginal bone loss was observed at the three-month follow-up (p=0.24).
• A statistically significant difference in marginal bone loss was found at six months (p<0.001), favoring the manual method.
• Average marginal bone loss at six months was lower with the manual method (0.51±0.20 mm) compared to the mechanized method (0.67±0.19 mm).

Conclusions:

• Both manual and mechanized dental implant insertion techniques are safe and lead to acceptable bone resorption.
• The manual insertion method demonstrated a trend towards less marginal bone loss at the six-month follow-up.
