Summary
This study presents a novel technique for single-implant restorations using adjustable titanium abutments. The method showed minimal marginal bone loss and no increased mucosal inflammation in patients.
Area of Science:
- Dental Implantology
- Prosthodontics
- Biomaterials
Background:
- Traditional fabrication of single-implant restorations can be technique-sensitive.
- Adjustable abutments offer potential for customization in implant prosthodontics.
Purpose of the Study:
- To describe an alternative fabrication technique for single-implant restorations using adjustable titanium abutments with direct porcelain application.
- To evaluate the clinical outcomes of restorations fabricated with this method in an early patient cohort.
Main Methods:
- A protocol involving healing abutments, implant impressions, and laboratory adjustment of final abutments was employed.
- Seventeen single crowns were consecutively placed in 14 patients and followed for 2 years.
Main Results:
- The clinical follow-up revealed minimal complications.
- The mean marginal bone loss after 1 year in function was 0.4 mm (SD +/- 0.57 mm).
Conclusions:
- The described protocol for single-implant restorations using adjustable titanium abutments did not appear to be associated with increased mucosal inflammation or marginal bone loss.
- This technique offers a viable alternative for fabricating single-implant restorations.
