Summary
This 12-year study shows Astra Tech dental implants are a reliable option for single-tooth replacements. Success rates were high, with minimal bone loss and few complications observed over time.
Area of Science:
- Dentistry
- Implantology
- Prosthodontics
Background:
- Single-tooth replacement is a common dental procedure.
- Implant-supported restorations offer a durable solution for missing teeth.
Purpose of the Study:
- To prospectively evaluate the 12-year clinical and radiographic outcomes of Astra Tech TiOblast® ST-implants used for single-tooth restorations.
Main Methods:
- 45 Astra Tech TiOblast® ST-implants were placed in 40 patients using a two-stage protocol.
- Clinical and radiographic assessments were conducted at prosthetic treatment completion, and at 5 and 12 years post-placement.
Main Results:
- After 12 years, 31 patients and 35 implants were evaluated.
- The overall failure rate was 10.3% (subject level) and 9.1% (implant level).
- Mean bone loss was 0.67 mm (subject) and 0.47 mm (implant); peri-implantitis affected 10% of subjects.
Conclusions:
- Astra Tech dental implants demonstrate a valid treatment option for single-tooth replacement.
- The 12-year outcomes suggest good long-term predictability for these implant-supported restorations.
