Digital VS. Conventional Ear Impression

Not Applicable

• Conditions: Patient Loss His Ear and Need Auricular Prosthesis
• Interventions: Device: medit intra oral scanner

• Registration Number: NCT04893902
• Lead Sponsor: Mohamed Mahmoud Dohiem

Brief Summary

What is known:

Ear impressions are made in conventional manner by impression materials which may affect the accuracy of the obtained data and consume time and effort .

What this study adds:

Predesigned ear markers facilitate ear scanning using an intraoral scanner that decreases the probability of in-accuracies using the conventional manner with less time and effort

Detailed Description

Prosthodontic maxillofacial rehabilitation of acquired or congenital ear defects is considered a challenging procedure. This clinical trial introduces a novel approach for digital scanning of the unaffected contralateral ear using an intraoral scanner in comparison to the conventional impression techniques. CAD/CAM is a very promising design and fabrication of an auricular prosthesis for patients with unilateral ear defects.

Purpose: This study aims to compare digital impression technique using an intra-oral digital scanner IOSfor the unaffected ear with markers /without markers versus traditional techniques with hydro colloidal impression materials.
