Ridge dimensional changes and implant stability utilizing the osseodensification protocol: A randomized clinical...

Area of Science:

• Dental Implantology
• Bone Grafting and Augmentation
• Periodontology

Background:

• Limited evidence exists comparing osseodensification drilling (OD) to standard drilling (SD) regarding alveolar ridge dimensions and implant stability.
• Understanding these differences is crucial for optimizing implant placement and long-term success.

Purpose of the Study:

• To compare the effects of OD and SD on alveolar ridge dimensional changes.
• To evaluate the impact of OD and SD on implant stability.
• To assess changes in buccal bone thickness (BBT) and implant stability over time.

Main Methods:

• A comparative study involving 15 patients and 20 pairs of implants.
• Measurement of ridge width changes at the crest and 5, 10 mm apical to the crest using a surgical guide.
• Recording of insertion torque and implant stability quotients (ISQ) post-placement and at 3, 6, 12 weeks.
• Analysis of 6-month post-operative buccal bone thickness changes using CBCT superimposition.

Main Results:

• OD resulted in greater ridge width changes at the crest and 5 mm apical compared to SD.
• OD maintained buccal bone thickness significantly better than SD at 6 months post-op.
• Implants placed with OD demonstrated higher insertion torque, ISQ values, and achieved high implant stability (HIS) more frequently.

Conclusions:

• OD promotes greater ridge dimensional changes during osteotomy preparation compared to SD.
• OD predictably maintains buccal bone thickness, reducing the risk of dehiscence and resorption.
• OD leads to superior insertion torque, higher ISQ values, and sustained high implant stability throughout healing.
