Brief Summary

This descriptive longitudinal study aimed to investigate the retention force of implant-supported overdentures applied to edentulous individuals at Marmara University Faculty of Dentistry, examine the retention force and its time-dependent change, and evaluate patient satisfaction.

Conditions

Edentulous Jaw

Keywords

Dental Prosthesis, Implant-Supported

Outcome Measures

Primary Outcomes (1)

• Change in retention force

  The retention of a complete implant overdenture prosthesis is defined as the minimum retention force (N) required to separate the male part of the attachment from the female part. The retention strength will be measured 3 times with a force gauge that allows the application of the retention force perpendicular to the occlusal plane of the prosthesis and parallel to the long axis of the implant, and the values will be averaged with a digital dynamometer. As the measurement value increases, it is concluded that the retention of the prosthesis increases. The measurements will be recorded on the 'Patient Measurement Card' at each control session. The retention of the implanted complete denture will be measured at the time of delivery of the implant overdenture to the patient and at the control sessions 1 week, 1 month, 3 months, and 6 months after the patient start to use the denture.

  6 months

Secondary Outcomes (1)

• Change in patient satisfaction

  6 months
