Experience with ITI osseointegrated implants at five centres in the UK

Area of Science:

• Dental Implantology
• Biomaterials Science
• Prosthodontics

Background:

• The ITI (International Team for Implantology) titanium implant system is a widely used dental prosthetic device.
• Assessing the long-term success of dental implants is crucial for patient outcomes and clinical practice.
• Multi-center studies provide robust data on implant performance in diverse patient populations.

Purpose of the Study:

• To evaluate the clinical performance and success rate of the two-part ITI titanium implant system.
• To analyze implant success across different prosthetic applications and anatomical locations.
• To report on a significant sample size of implants and patients over a defined follow-up period.

Main Methods:

• A retrospective analysis of 461 ITI titanium implants placed in 176 patients across five UK centers.
• Data collection over a 3-year period, assessing implant success based on predefined criteria.
• Categorization of prostheses including mandibular overdentures and crown and bridge restorations.

Main Results:

• An overall success rate of 94% was achieved for implants supporting mandibular overdentures and crown and bridge prosthetics.
• The study documented the performance of 189 prostheses supported by the ITI titanium implants.
• A comparatively lower success rate was observed for implants placed in the edentulous maxilla.

Conclusions:

• The ITI titanium implant system exhibits a high success rate, particularly for mandibular restorations and fixed prosthetics.
• Clinical outcomes suggest the system is reliable, though caution may be warranted for maxillary applications.
• Further investigation into factors influencing success in the edentulous maxilla is recommended.
