A four-year retrospective study of 3i threaded implants
Australian Prosthodontic Journal
|January 1, 1995
Summary
Osseointegrated implants, particularly the 3i threaded system, demonstrate high success rates in dental restoration. This study confirms their reliability for various tooth loss conditions and maxillofacial applications, achieving a 97.75% overall success rate.
Area of Science:
- Dental Implantology
- Restorative Dentistry
- Biomaterials Science
Background:
- Osseointegrated implants represent a significant advancement in modern dentistry.
- Initially for edentulous patients, their application now spans diverse tooth loss scenarios, maxillofacial prosthetics, and orthodontics.
Purpose of the Study:
- To evaluate the clinical outcomes of 3i (Implant Innovations Inc.) threaded implants.
- To assess the success rates of these implants in a multicentre retrospective study over a four-year period.
Main Methods:
- Retrospective analysis of 327 patients receiving 1047 3i threaded implants.
- Exclusion of 8 patients (22 implants) due to lack of evaluable data.
- Analysis of implant survival and failure rates in the mandible and maxilla.
Main Results:
- A total of 319 patients with 1025 implants were analyzed.
- Implant failure occurred in 9 mandibular and 14 maxillary implants.
- Success rates were 98.2% in the mandible and 97.3% in the maxilla, with an overall mean of 97.75%.
Conclusions:
- The 3i threaded implant system demonstrates high success rates comparable to other titanium implants.
- Adherence to surgical and restorative principles ensures confident use of this implant system.
- Osseointegrated implants are a reliable solution for supporting prostheses in diverse dental applications.
