Osseodensification versus conventional site preparation in cylindrical implants: A randomized controlled trial.

Area of Science:

• Dental Implantology
• Biomaterials Science
• Surgical Techniques

Background:

• Osteotomy preparation is critical for dental implant success.
• Conventional drilling (CD) removes bone, potentially compromising primary stability.
• Osseodensification (OD) compacts bone, aiming to enhance stability and density.

Purpose of the Study:

• To compare implant stability outcomes between OD and CD techniques for cylindrical implants.
• To evaluate the clinical efficacy and patient experience of OD versus CD.
• To determine if OD offers a significant advantage over CD in osteotomy preparation.

Main Methods:

• Randomized controlled trial comparing OD and CD protocols for single-tooth implants.
• Assessment of implant stability via insertion torque value (ITV) and implant stability quotient (ISQ).
• Patient-reported outcomes including pain, swelling, and bleeding using a visual analog scale (VAS).

Main Results:

• No significant differences in ISQ or ITV between OD and CD groups at placement or 3 months.
• Mandibular implants exhibited higher ISQ values than maxillary implants, irrespective of drilling method.
• VAS scores indicated comparable postoperative experiences for both techniques.

Conclusions:

• Osseodensification (OD) is non-inferior to conventional drilling (CD) for cylindrical implants regarding stability.
• Both techniques demonstrated comparable clinical outcomes and patient tolerability.
• The choice between OD and CD can be individualized, considering factors beyond assumed universal benefits of OD.
