Summary
This study introduces a digital method for transferring upper jaw positions without physical dental casts. This technique enhances digital workflows for prosthetics using intraoral scans and CAD applications.
Area of Science:
- Dental Technology
- Digital Dentistry
- Prosthodontics
Background:
- Traditional dental prosthetics rely on physical casts and articulators for accurate jaw positioning.
- Integrating digital workflows, particularly intraoral scanning, presents challenges in capturing precise spatial relationships of the maxillary arch.
Purpose of the Study:
- To present a novel digital method for transferring the upper jaw (maxillary) arch position.
- To eliminate the need for traditional gypsum-mounted casts in the digital prosthetic workflow.
Main Methods:
- Utilized a facebow, transfer table, and reference block integrated with a CAD (Computer-Aided Design) application.
- Employed intraoral scanning for impression capture to obtain maxillary arch placement.
- Focused on orienting the maxillary arch within anatomical reference planes and mandibular rotational axes.
Main Results:
- Successfully demonstrated a digital transfer method for the upper maxillary arch position.
- The technique bypasses the requirement for physical casts mounted with articulating gypsum.
- Facilitates seamless integration into digital prosthetic workflows.
Conclusions:
- The described digital transfer method is effective for accurately positioning the maxillary arch.
- This technique streamlines the digital prosthetic workflow, especially when using intraoral scanning.
- It enables precise spatial orientation of the maxillary arch relative to mandibular movement axes.
