A Digital-To-Physical Mounting Strategy without Record Bases using A 3D-Printed Gyroid-Based Mounting Jig

Area of Science:

• Dental Technology
• Prosthodontics
• Digital Dentistry

Background:

• Traditional methods for transferring interocclusal relationships to mechanical articulators often require record bases to stabilize gypsum casts, especially in cases with insufficient posterior occlusal support.
• These conventional techniques can be time-consuming and may necessitate additional clinical appointments.

Purpose of the Study:

• To describe a novel digital-to-physical workflow for efficient dental articulator mounting.
• To demonstrate a proof-of-concept for a streamlined process using intraoral scanning and 3D printing.

Main Methods:

• A digital workflow combining intraoral scanner-derived interocclusal registration with a patient-specific, 3D-printed gyroid-based mounting jig was developed.
• Digital mounting data was acquired intraorally.
• The digital mounting was transferred to gypsum casts mounted on an articulator using the 3D-printed jig.

Main Results:

• The digital mounting was successfully transferred to gypsum casts on an articulator without requiring an additional clinical visit.
• The workflow was validated in a single clinical case.
• The described approach facilitated efficient articulator mounting.

Conclusions:

• This digital-to-physical workflow offers a potentially reduced and more efficient method for articulator mounting in dentistry.
• The use of intraoral scanning and patient-specific 3D-printed jigs simplifies the transfer of interocclusal relationships.
• This technique may be particularly beneficial in clinical situations with insufficient posterior occlusal support.
