NCT07037407 | Completed DMC

• 1 other identifier: MSA University REC-D4210-4
• Study Type: interventional
• Target: 12
• Locations: 1 country

Brief Summary

In vivo prospective clinical study will be designed, 12 participants will be included. After intraoral scanning, a conventional impression is made for each patient. The groups will be compared for accuracy.

Conditions

Edentulism; Edentulous Alveolar Ridge; Edentulous Alveolar Ridge With Labial Resorption; Flabby Ridge

Keywords

Flabby ridge; IOS

Outcome Measures

Primary Outcomes (1)

• accuracy evaluation

  Accuracy Evaluation: The accuracy of the digital impressions versus conventional impression based on trueness and precision will be evaluated. \- Trueness: Trueness is the degree of agreement between the digital impression and the reference scan. To assess trueness, we will measure the deviation between the reference and scanned files. Precision: Precision is a statistical measure that quantifies the level of similarity between repeated samples within the same group. In the context of this study, the IOS impression STL files will be compared to each other in a manner similar to the previous comparisons
