Summary
Immediate loading (IL) of dental implants placed in fresh extraction sockets shows comparable long-term clinical and radiographic outcomes to conventional loading. This approach does not negatively impact implant survival rates or bone level changes over time.
Area of Science:
- Dentistry
- Oral Implantology
- Prosthodontics
Background:
- Dental implants are a common solution for tooth loss.
- Immediate loading protocols offer potential advantages in treatment efficiency.
- Long-term outcomes of immediate loading in extraction sockets require thorough evaluation.
Purpose of the Study:
- To compare long-term clinical and radiographic outcomes of immediate loading (IL) versus conventional loading.
- To assess implants placed immediately into fresh extraction sockets.
Main Methods:
- A cohort of 21 patients with 35 implants in postextraction sites was analyzed.
- Data included demographics, implant details, and periapical radiographs.
- Long-term marginal bone level changes and implant survival rates were calculated over a mean 6-year follow-up.
Main Results:
- The cumulative implant survival rate was 96.5%.
- Mean crestal bone levels at longest follow-up were comparable between immediate loading (0.144 ± 0.705 mm) and delayed loading (0.161 ± 0.877 mm).
- Mean implant aesthetic score was 7.
Conclusions:
- Immediate loading of implants in fresh extraction sockets does not adversely affect long-term prognosis.
- Clinical and radiographic outcomes are similar to conventional loading protocols.
