Masticatory Ability for a Single Implant Mandibular Overdenture Retained by Two Different Attachments: A Randomized...

Area of Science:

• Dental Implantology
• Prosthodontics
• Oral Rehabilitation

Background:

• Edentulism significantly impairs masticatory function and quality of life.
• Single implant-retained mandibular overdentures offer a solution for edentulous patients.
• Attachment systems play a crucial role in the stability and function of overdentures.

Purpose of the Study:

• To compare the subjective masticatory ability between ball and Cendres+Métaux Locator (CM-LOC) attachments.
• To evaluate the efficacy of these attachments in single implant-retained mandibular overdentures over a 24-month period.
• To assess the long-term performance of different attachment systems in improving chewing function.

Main Methods:

• A randomized clinical trial involving 80 completely edentulous patients.
• Patients received a single implant-retained mandibular overdenture with either a ball or CM-LOC attachment.
• Masticatory ability was subjectively assessed using a questionnaire at baseline and at multiple follow-up intervals up to 24 months.

Main Results:

• Both attachment groups demonstrated significant improvements in subjective masticatory ability from baseline.
• No statistically significant differences in masticatory ability scores were found between the ball and CM-LOC attachment groups throughout the 24-month follow-up.
• While both attachments performed similarly, the ball attachment showed slightly better subjective masticatory ability scores at the 24-month mark.

Conclusions:

• Single implant-retained mandibular overdentures effectively improve subjective masticatory function in edentulous patients.
• Both ball and CM-LOC attachments provide comparable subjective improvements in chewing ability over a 24-month period.
• The choice between ball and CM-LOC attachments may not significantly impact long-term subjective masticatory performance for single implant overdentures.
