Brief summary

Comparing digital attachment pickup prior to jaw relation registration with intraoral pickup using digitally constructed mandibular overdenture bases is the aim of this study.

Interventions

DEVICEdigital pickup of attachment before jaw relation

Arm 1 - Digital Pick-up Before Jaw Relation Intervention Type: Device Description (short): Extraoral digital pick-up of ball attachments on master cast, CAD/CAM denture base fabrication, jaw relation registration, and denture insertion.

DEVICEintraoral pickup of attachment during insertion

Arm 2 - Intraoral Pick-up During Insertion Intervention Type: Device Description (short): Intraoral direct pick-up of ball attachments during denture insertion after CAD/CAM denture base fabrication and jaw relation registration.
