Summary
Immediate dental implant placement shows comparable survival rates to delayed placement. While overall survival is similar, some studies indicate slightly higher failure rates with immediate implants.
Area of Science:
- Dentistry
- Oral Surgery
- Implantology
Background:
- Dental implant placement timing is crucial for successful outcomes.
- Immediate implant placement offers potential advantages like reduced treatment time.
- Delayed implant placement is a traditional approach with established success rates.
Purpose of the Study:
- To compare implant survival rates between immediate and delayed dental implant placement in adults.
- To analyze differences in implant survival based on placement timing.
Main Methods:
- A systematic literature search was conducted in CENTRAL, MEDLINE, and Scopus (2014-2022).
- Included were randomized controlled trials and comparative studies, assessed for bias.
- Implant survival data were meta-analyzed using RevMan v.5.3.
Main Results:
- Ten studies (6 RCTs, 4 non-randomized) were included.
- Immediate placement: 341 implants (97.4% survival).
- Delayed placement: 359 implants (97.5% survival).
Conclusions:
- No significant difference in implant survival rates between immediate and delayed placement.
- Immediate placement showed slightly more failures in some studies (90-95% survival).
- Delayed placement consistently demonstrated survival rates above 95%.
