Summary

The goal of this clinical trial is to evaluate denture retention in intra-orally scanned versus extra-orally scanned digitally printed maxillary dentures in completely edentulous patients. The main question is : 1. Do intra-orally scanned dentures provide better retention compared to extra-orally scanned dentures? Researchers will compare the intra-orally scanned denture group to the extraorally scanned denture group to determine if one method leads to superior retention records.

Participants will:

• Receive both types of dentures (intra-orally scanned and extra-orally scanned), with a three-week wash-out period between each intervention. The study aims to provide evidence on the optimal scanning method for digitally printed maxillary dentures in edentulous patients.

Conditions

  • Complete Edentulism

Interventions

DEVICE

Intaorally scanned methods

the intraoral scanning method involves capturing digital impressions of the oral cavity directly using the 3 shape scanner . this method eliminates the need for traditional impression material providing a more comfortable and precise imaging process , the digital impressions are the utilized to design and fabricate maxillary dentures using 3D printing technology . the intervention focuses on evaluating denture's retention

DEVICE

extraorally scanned methods

The extra-oral scanning method involves creating conventional impressions of the oral cavity using traditional impression materials. These impressions are then scanned externally using the 3Shape scanner to produce digital models. The digital models are used to design and fabricate maxillary dentures through 3D printing technology. This intervention aims to assess denture retention
