Osseointegration: current state of the art

Area of Science:

• Oral surgery
• Biomaterials science
• Prosthodontics

Background:

• Osseointegrated dental implants are crucial for restoring function and aesthetics in edentulous patients.
• The Brånemark and ITI implant systems are well-documented, while others lack sufficient long-term data.
• Assessing the long-term success rates of various osseointegrated oral implants is essential for clinical decision-making.

Purpose of the Study:

• To evaluate the long-term clinical success rates of the Brånemark osseointegrated implant system.
• To compare the documented success of Brånemark and ITI implants with other less-documented systems.
• To provide evidence-based data on the reliability of osseointegrated dental implants.

Main Methods:

• Analysis of controlled multicenter studies on Brånemark osseointegrated implants.
• Longitudinal follow-up of maxillary and mandibular Brånemark bridges over 5, 10, and 15 years.
• Review of documented success rates for ITI implants and other osseointegrated oral implant systems.

Main Results:

• The Brånemark implant demonstrated a 5-year success rate of 86.4% for maxillary and 96.8% for mandibular applications.
• Long-term follow-up of Brånemark bridges showed sustained high success rates: 96% (5yr), 95% (10yr), and 93% (15yr) for maxillary; 99% (5, 10, 15yr) for mandibular.
• The ITI implant system is well-documented, contrasting with many other osseointegrated implants with poor documentation.

Conclusions:

• The Brånemark osseointegrated implant system exhibits high and durable success rates in both maxillary and mandibular applications.
• There is a significant disparity in the level of documentation and reported success among different osseointegrated oral implant systems.
• Many current osseointegrated products may yield poor long-term results, similar to previously used soft-tissue-anchored devices.
