About this study

Official title: Investigation of Time-Dependent Change of Retention Force of Mandibular Implant Overdenture and Evaluation of Patient Satisfaction: A Clinical Follow-up Study

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

What is being measured

The primary outcome is the main question the study is designed to answer.

  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.

    Measured: 6 months

Secondary outcomes (1)
  1. Change in patient satisfaction

    Patients' overall satisfaction, comfort, speech ability, prosthesis stability, retention, aesthetics, and ease of cleaning will be assessed using VAS measurements. The rating words will be 'very satisfied' and 'not at all satisfied,' and patients will be asked to draw a vertical line on a 10 cm horizontal line at the point that best represents their perception. The VAS total score is between 0-10. As the score increases, it is concluded that the patient's satisfaction increases. Patients will be asked to fill out the VAS questionnaire form during the 1st month (TI) after using the prosthesis and at 3 months and 6 months of control sessions.

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

An observational study of Edentulous Jaw, run by Marmara University at 1 site in Turkey (Türkiye).

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 12 Mar 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in retention force (time frame: 6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05675566, which also lists 7 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Mar 2024.
