Using Two Different Attachments in Mandibular Implant Overdenture Cases in Order to Retention and Patient Satisfaction

December 11, 2024 updated by: Noha Taha Kamel Taha Alloush, Al-Azhar University

Comparing Two Different Attachments Retaining Mandibular Implant Overdenture Regarding Retention and Patient Satisfaction (Randomized Clinical Trail)

The Goal of the clinical trail is to evaluate the efficacy of Bar- OT Equator attachment on retention and patient satisfaction in comparison to the standard technique using Bar- clip attachment.

Patients will visit the clinic after the surgery and after the attachment insertion for check ups and during the follow up periods ( at denture insertion, 3 months and 6 months)

Study Overview

Detailed Description

patients will receive upper complete dentures and lower complete overdentures. The upper complete denture will be mucosa supported and the lower complete denture will be supported and retained for all patients by two dental implants in the inter-foraminal region. Patients will be divided into two equal groups; Group I will be retained by Bar-Clip attachment, while Group II will be retained by Bar- OT Equator attachment. Both groups will be functionally loaded after three months of insertion.

Retention of lower denture will be measured using digital force gauge and Patient satisfaction was evaluated with a standard 5-point Liker scale questionnaire. All parameters will be measured at denture insertion, 3 month, and 6 month later.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Retention
Time Frame: it will be measured at denture insertion, 3 month, and 6 month later

Retention will be measured using digital force gauge A digital force meter was used to measure denture resistance to vertical displacement (i.e., retention) by applying a pulling force on a metal hook located in the geometric center of each mandibular conventional denture that was identified on the lower cast at the intersection of three lines bisecting the angles of the triangle, formed by both retromolar pads and the midline.

Measurement of mandibular denture retention:

The patient was instructed to place his head on chin rest and occlusal plane was set parallel to the floor. Tongue freedom was checked then and three minutes seating time was allowed before taking the measurements. A vertical pulling force was applied using the metallic probe of the digital force-meter that was attached to the hook present at the geometric center of mandibular denture. Average value of six readings was recorded.

it will be measured at denture insertion, 3 month, and 6 month later

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Patient satisfaction
Time Frame: it will be measured at denture insertion, 3 month, and 6 month later.
Patient satisfaction was evaluated with a standard 5-point Liker scale questionnaire, which included subjective parameters such as initial adaptability, post insertion problems, aesthetics, masticatory ability, speech, retention. Patients were asked to respond to questions given in the questionnaire
it will be measured at denture insertion, 3 month, and 6 month later.
