A comparative study on bone density before and after implant placement using osseodensification technique: a clinical evaluation.

Background: Dental implant success critically depends on the primary stability of the implant, which is significantly influenced by the bone density at the osteotomy site. Traditional drilling techniques for osteotomy preparation often compromise bone volume and quality. This study aimed to evaluate the impact of osseodensification, a novel osteotomy preparation technique, on bone density and implant stability. The technique utilizes specialized drills that operate in a counter-clockwise direction to compact autografted bone laterally and apically, preserving and enhancing bone density.

Methods: A total of 32 patients undergoing dental implant surgery were included in this study. Pre-operative and post-operative bone densities at the apical, mesial, and distal regions of the osteotomy sites were measured using Dentascan (CT) and analyzed with Radiant DICOM software. The study utilized osseodensification drills for osteotomy preparation, comparing pre-operative and post-operative bone densities to assess the technique's efficacy.

Results: The study found a statistically significant increase in bone density post-operatively (p < 0.001), with the greatest improvement observed in the distal region, followed by the mesial and apical regions. The findings underscore osseodensification's effectiveness in enhancing bone density and primary stability, with the distal region exhibiting the highest bone density.

Conclusion: Osseodensification represents a significant advancement in implant dentistry for osteotomy preparation. By preserving and increasing bone density through compact autografting, this technique not only improves primary stability but also offers potential benefits in indirect sinus lifting and alveolar ridge expansion. The study advocates for the broader adoption of osseodensification drills in clinical practice to achieve better outcomes in dental implantology.
