Summary

This study aims to compare the trueness and precision of three impression methodologies photogrammetry, digital intraoral scanning with splinted scan bodies, and conventional open tray impressions in the context of the All-on-X treatment concept. This will provide valuable evidence for clinicians considering digital workflows for implant-supported prostheses. Does the use of photogrammetry and digital impression techniques with splinted scan bodies result in improved accuracy in implant position transfer in the All-on-X concept compared to conventional open tray impressions?

Conditions

  • Truness of Impression Techniques in All on x Cases
  • Trueness of Full Arch Implant Prosthesis Impression

Interventions

DEVICE

photogrammetry based full arch impression

use of photogrammetry system to capture the positions of All on X implants digitally without physical impression material. This technique aims to achieve precise measurements and increase patient satisfaction

DEVICE

Digital Impression Using Splinted Scan Bodies

Digital full-arch impression using splinted scan bodies connected with resin to enhance stability. An intraoral scanner captures the splinted assembly for framework fabrication. Accuracy and patient satisfaction will be evaluated.

PROCEDURE

Conventional Open-Tray Implant Impression

Traditional full-arch open-tray impression using polyether or VPS material with splinted impression copings. This serves as the standard comparator for evaluating accuracy and patient satisfaction.
