Summary
Early loading of sand-blasted, large-grit and acid-etched (SLA) implants for full-arch prostheses in the maxilla is predictable. High implant survival and prosthesis success rates were observed with stable marginal bone levels.
Area of Science:
- Dental Implantology
- Prosthodontics
- Biomaterials
Background:
- Maxillary full-arch prostheses require stable implant support.
- Early loading protocols aim to reduce treatment time.
- Sand-blasted, large-grit and acid-etched (SLA) implants offer enhanced surface properties.
Purpose of the Study:
- To evaluate the predictability of early-loaded ITI SLA implants.
- To assess the stability and success of maxillary fixed full-arch prostheses supported by these implants.
Main Methods:
- Ninety-one ITI SLA implants were placed in 12 edentulous maxillae.
- Resonance frequency analysis (RFA) and panoramic radiography were used to assess implant stability and bone levels.
- Prostheses were attached at 6 weeks post-surgery, with follow-ups.
Main Results:
- Implant survival rate was 98.90% and prosthesis success rate was 100%.
- No significant marginal bone resorption was observed compared to baseline.
- Implant Stability Quotient (ISQ) values indicated stable osseointegration.
Conclusions:
- Early loading of ITI SLA implants for maxillary fixed full-arch prostheses is a predictable treatment modality.
- The protocol demonstrated high success rates and maintained bone stability.
