Dental Implants in Adults With Intellectual Disabilities: A Multicenter Retrospective Study. Part 1: Implant Outcomes

Area of Science:

• Dental Implantology
• Oral Rehabilitation
• Intellectual Disabilities

Background:

• Limited data exists on dental implant performance in adults with intellectual disabilities (ID).
• Peri-implant health and outcomes in this population require further investigation.

Purpose of the Study:

• To evaluate dental implant outcomes in adults with non-syndromic ID.
• To identify factors influencing peri-implant health, complications, and implant loss.

Main Methods:

• Multicenter retrospective cohort study of 137 adults with non-syndromic ID.
• Analysis of 453 dental implants across 7 specialized centers in Europe and South Korea.
• Standardized data collection on patient, implant, prosthetic, and follow-up variables.

Main Results:

• High implant survival rate of 92.3% after a mean follow-up of 75.9 months.
• 63.6% of implants were healthy, with mucositis (23.4%) and peri-implantitis (4.4%) being common.
• Tissue-level implants, cement-retained prostheses, and general anesthesia for impressions were linked to outcomes.

Conclusions:

• Dental implant therapy is a viable long-term treatment for adults with non-syndromic ID.
• High survival and success rates are attainable with appropriate implant selection and management.
• Behavioral management and prosthetic choices are key to successful outcomes in this population.
