Effect of Ball and Bar Attachment Type on Patient Satisfaction Using Two-Implant-Retained Mandibular Overdenture: A...

Area of Science:

• Dental Implantology
• Prosthodontics
• Biomaterials

Background:

• Two-implant-retained overdentures are a preferred treatment for edentulous mandibles.
• Patient satisfaction with attachment type is crucial for successful overdenture use.
• Conventional complete dentures offer a baseline for comparison.

Purpose of the Study:

• To compare patient satisfaction between ball-socket and bar-clip attachments in two-implant-retained mandibular overdentures.
• To assess patient preference between the two attachment types.
• To evaluate satisfaction levels against conventional dentures.

Main Methods:

• A within-subject crossover randomized clinical trial involving 20 edentulous patients.
• Patients used conventional dentures, followed by overdentures with ball and bar attachments sequentially for 3 months each.
• Satisfaction questionnaires were administered at baseline, after each attachment phase, and a final preference was recorded.

Main Results:

• No statistically significant difference in patient satisfaction was observed between ball-socket and bar-clip attachments.
• Patient satisfaction significantly improved with both attachment types compared to baseline conventional dentures.
• A slight majority preferred ball attachments (11 patients) over bar attachments (9 patients) at study conclusion.

Conclusions:

• Both ball-socket and bar-clip attachments provide comparable patient satisfaction for two-implant-retained mandibular overdentures.
• Neither attachment type demonstrated a statistically significant preference over the other.
• Overall patient satisfaction is enhanced by implant-retained overdentures compared to conventional dentures.
