Effects on Ridge Dimensions, Bone Density, and Implant Primary Stability with Osseodensification Approach in Implant...

Area of Science:

• Dental Implantology
• Biomaterials Science
• Bone Regeneration

Background:

• Conventional drilling for dental implants can lead to bone loss.
• Osseodensification is a newer technique aiming to preserve and enhance bone during osteotomy.
• Comparing these techniques is crucial for optimizing implant success.

Purpose of the Study:

• To compare bone expansion, density changes, and implant primary stability between osseodensification and conventional drilling.
• To evaluate the effect of each technique on peri-implant bone dimensions and quality.
• To assess bone-to-implant contact (BIC%) differences.

Main Methods:

• Bovine rib bone segments were divided into osseodensification and conventional drilling groups.
• Implants were placed, and peri-implant bone density was measured before and after osteotomy.
• Laser scanning assessed crestal bone width and volumetric expansion; histomorphometry determined BIC%.

Main Results:

• Osseodensification significantly increased peripheral and apical bone mineral density and peripheral BIC%.
• Both techniques increased bone volume and width post-implant placement.
• No significant differences were observed in volume/width changes or implant stability between the groups.

Conclusions:

• Osseodensification enhances bone mineral density and primary bone-to-implant contact.
• Both osseodensification and conventional drilling can augment ridge dimensions in narrow alveolar ridges.
• Further research is needed to fully elucidate the long-term benefits of osseodensification.
