Treatment and study plan

digital pickup of attachment before jaw relation

Device

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.

intraoral pickup of attachment during insertion

Device

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.

Primary outcomes

  1. Changes in Peri-implant marginal alveolar bone height using digital periapical radiograph at baseline (definite insertion), 6 months, ,and 12 months after insertion

    Time frame: at baseline (definite insertion), at 6 months, and after 12 months after insertion
