Passive Fit and Time Efficiency in All On-X Implants Protocols Using Photogrammetry, Splinted Scan Bodies, and Conventional Impression Technique

NCT07235072 · Status: NOT_YET_RECRUITING · Phase: NA · Type: INTERVENTIONAL · Enrollment: 14

No results posted yet for this study

Summary

compare the passive fit of three impression techniques: photogrammetry, intraoral digital scanning with splinted scan bodies, and the conventional open-tray impression technique, within the context of the All-on-X treatment concept. This comparison is expected to provide valuable clinical evidence to support clinicians in making informed decisions when considering the adoption of digital alternatives to conventional methods.

Conditions

  • Passive Fit of Full-arch Implant Prostheses

Interventions

DEVICE

Photogrammetry-Based Full-Arch Impression

Use of a photogrammetry system to capture the positions of All-on-X implants digitally without physical impression materials. The technique aims to achieve precise passive fit and reduce chairside working time. Measurements of passive fit discrepancy and total procedure time will be recorded

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. Passive fit and working time 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 passive fit and procedure duration
