Summary
Dental implant restorations using the Brånemark system showed a high success rate over a 78-month period. Most complications were minor soft tissue issues, with few patients discontinuing prosthesis use.
Area of Science:
- Dentistry
- Biomaterials Science
Background:
- Dental implants have revolutionized tooth replacement.
- The Brånemark system is a well-established implant technology.
Purpose of the Study:
- To evaluate the long-term outcomes and complication rates of Brånemark system implants.
- To assess the success of implant-supported prostheses in a large patient cohort.
Main Methods:
- Retrospective analysis of 353 patients receiving 1,778 Brånemark system implants.
- Data collected over a 78-month period (1983-1990) at the Mayo Clinic.
- Categorization and analysis of implant and prosthesis complications.
Main Results:
- A total of 1,778 implants were placed in 407 jaws across 353 patients.
- The most frequent complications were soft tissue related.
- 152 patients experienced no complications, and 37 had only one occurrence.
- Prosthesis use was permanently discontinued in only 4 patients.
Conclusions:
- Brånemark system implants demonstrate a favorable long-term outcome with manageable complication rates.
- Soft tissue complications are the most common but generally treatable.
- High patient satisfaction and prosthesis retention rates were observed.
