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

Conditions

Summary

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.

Eligibility

Inclusion Criteria8

  • 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 Criteria5

  • 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).

Interventions

DEVICEIntraoral photogrammetry (IOP)

IOP will be used in the study to take a digital impression for the implants. The scanner will be used to record the soft tissue anatomy and trans-mucosal abutments. 3D Scan bodies will be fitted on the trans-mucosal abutments that are screwed on the implants to capture their position and scanning will be done. A scan of the soft tissue and scan bodies will finally be conducted.

DEVICEIntraoral scanner (IOS)

Intra-oral scanner will be used in the study to take a digital impression for the implants. 3D printed generic Scan bodies with unified shape and length replacing the traditional transfer copings will be press fitted on the trans-mucosal abutments and pickup cylinders that are screwed on the implants to capture their position and intra-oral scanning will be done.
