Summary
Osseodensification significantly enhances primary implant stability in narrow posterior mandibular ridges compared to conventional ridge splitting. This technique offers a promising advantage for predictable dental implant outcomes in challenging bone conditions.
Area of Science:
- Oral and Maxillofacial Surgery
- Dental Implantology
- Biomaterials Science
Background:
- Narrow mandibular ridges pose challenges for dental implant placement.
- Alveolar ridge augmentation techniques are often necessary for successful implantology.
- Comparing techniques for primary implant stability in compromised bone is clinically relevant.
Purpose of the Study:
- To compare the primary stability of dental implants placed via osseodensification versus conventional ridge splitting.
- To evaluate implant stability quotient (ISQ) values in narrow posterior mandibular ridges.
- To determine the efficacy of osseodensification for enhancing implant stability.
Main Methods:
- Randomized controlled trial with 14 patients and 28 implants.
- Two groups: conventional ridge splitting and osseodensification.
- Primary stability measured using the Osstell Mentor device (ISQ values).
Main Results:
- Osseodensification group showed significantly higher ISQ values (p < 0.001).
- Implants placed with osseodensification demonstrated superior primary stability.
- No significant difference in stability between molar sites within groups.
Conclusions:
- Both techniques allow implant placement in narrow mandibular ridges.
- Osseodensification provides significantly greater primary implant stability.
- Osseodensification may offer predictable outcomes in compromised ridge scenarios.
