Scan Time and Prosthetic Complications of Intraoral Scanning Versus Intraoral Photogrammetry for Full-Arch Titanium Framework With Zirconia Overlay Implant Screw-Retained Prostheses

Scan Time and Prosthetic Complications of Intraoral Scanning Versus Intraoral Photogrammetry for Full-Arch Titanium Framework With Zirconia Overlay Implant Screw-Retained Prostheses: A Randomized Clinical Trial

This study aims to evaluate the effect of intra-oral scanning and intra-oral photogrammetry on scan time and prosthetic complications in patients receiving full-arch titanium framework with zirconium overlay implant screw-retained prostheses.

Participants will:

Receive a full arch implant prosthesis and scan time will be recorded. Prosthetic complications (e.g., screw loosening, framework fracture, zirconia chipping) will be recorded at 3 and 6-month follow-up period post-delivery and we will manage complications at the time of prosthetic complication occurrence.

Inclusion Criteria:

• Patients requiring maxillary and/or mandibular full arch screw-retained implant-supported prosthesis.
• Number of implants placed per arch ranging from 4-6 implants per arch.
• Completely edentulous patients with sufficient inter-arch space to receive fixed prosthesis (Crown height space 9-15 mm per arch).
• Adequate zone of keratinized mucosa (> 2mm width).
• Both genders.
• Acceptable oral hygiene.
• Cooperative patients.
• Controlled systemic diseases (Diabetes, hypertension).

Exclusion Criteria:

• Completely edentulous patients with insufficient inter-arch space to receive fixed prosthesis (Crown height space lesser than 9mm per arch).
• Completely edentulous patients with in-adequate zone of keratinized mucosa (< 2mm).
• Un cooperative patients.
• Poor oral hygiene.
• Uncontrolled systemic diseases (Diabetes, hypertension).
