Summary
Immediate loading dental implants placed in fresh extraction sockets show high survival and success rates, comparable to traditional methods. Younger patients and harder bone correlate with better outcomes and less bone loss.
Area of Science:
- Dental Implantology
- Oral Surgery
- Prosthodontics
Background:
- Immediate loading (IL) dental implants are a time-saving procedure.
- Limited data exists on postextractive IL implants with short follow-ups.
- Investigating IL implants in fresh extraction sockets is crucial.
Purpose of the Study:
- To evaluate the survival and success rates of postextractive IL implants.
- To assess factors influencing marginal bone loss in these implants.
- To compare outcomes with traditional two-stage procedures and implants in healed sites.
Main Methods:
- Retrospective study of 1,074 IL fixtures (416 postextractive, 658 in healed sites) from 1995-2004.
- Mean follow-up of 3 years across multiple implant systems.
- General linear model used to identify factors associated with marginal bone loss.
Main Results:
- High survival rate of 99.3% (8/1,074 implants lost).
- No statistical differences in survival/success rates among variables.
- Younger age (≤55 years) and harder bone positively correlated with reduced bone loss.
Conclusions:
- Postextractive IL implants demonstrate high survival and success rates.
- Outcomes are comparable to two-stage procedures and IL implants in healed sites.
- Older age and poorer bone quality are associated with slightly increased bone resorption.
