Summary
Immediate loading of mono-cortically anchored dental implants in the mandible is safe and predictable. Implant stability remains excellent after a two-year follow-up period, demonstrating successful outcomes.
Area of Science:
- Dental Implantology
- Oral Surgery
- Biomaterials Science
Background:
- Immediate loading protocols for dental implants are increasingly utilized.
- Mono-cortical engagement offers a specific anchorage technique.
- Assessing long-term stability and bone levels is crucial for predictable outcomes.
Purpose of the Study:
- To evaluate two-year outcomes of immediate loading for mono-cortically engaged implants.
- To assess marginal bone level changes and implant stability.
- To determine the safety and predictability of this implant loading technique.
Main Methods:
- Prospective study involving 30 edentulous patients (average age 67.3 years).
- Four Astra Tech, Ti-Oblast® implants placed using mono-cortical anchorage.
- Resonance frequency analysis (RFA) for primary stability; marginal bone level evaluation over 24 months.
Main Results:
- Significant reduction in marginal bone level observed postoperatively compared to baseline (p < 0.05).
- No significant differences in resonance frequency analysis (RFA) at 12 and 24 months.
- Five implants were lost during the initial 6 weeks, leading to patient exclusion.
Conclusions:
- Immediate loading of mono-cortically engaged implants in the edentulous mandible is a safe procedure.
- The technique demonstrates predictable outcomes with excellent implant stability at the 2-year mark.
- Marginal bone loss occurs but does not compromise overall implant stability.
