Summary
Immediate functional loading of palatal implants up to 3 N showed comparable bone-to-implant contact (BIC) rates to conventional loading. This supports immediate indirect loading as a viable option for orthodontic anchorage.
Area of Science:
- Orthodontics
- Dental Implantology
- Biomaterials
Background:
- Palatal implants are crucial for orthodontic anchorage.
- Evaluating different loading protocols is essential for optimizing treatment outcomes.
Purpose of the Study:
- To compare the clinical performance and bone-to-implant contact (BIC) rates of immediate functional loading versus conventional loading for palatal implants.
Main Methods:
- Two groups of patients received palatal implants: immediate functional loading (Group 1, n=36) within 24h and conventional loading (Group 2, n=40) after 12 weeks.
- Orthodontic forces ranged from 1 to 3 N.
- Implants were explanted and analyzed histologically for BIC rates.
Main Results:
- Both loading protocols demonstrated initial stability.
- Implant survival rates were high, with minor losses (3/36 in Group 1, 1/40 in Group 2).
- Median BIC rates were 76% (Group 1) and 84% (Group 2), with no statistically significant difference (P=0.262).
Conclusions:
- Immediate indirect loading of palatal implants with forces up to 3 N is clinically supported.
- Histological evaluation indicates that immediate loading achieves similar bone-to-implant contact rates as conventional loading.
