Area of Science:

  • Dentistry
  • Dental Mechanics
  • Prosthodontics

Background:

  • Accurate programming of semi-adjustable articulators is crucial for effective dental restorations.
  • Traditional methods for recording jaw relations can be time-consuming and prone to inaccuracies.
  • A reliable technique for obtaining centric relation and jaw movement data is needed.

Purpose of the Study:

  • To present a novel universal jig for recording centric relation and programming semi-adjustable articulators.
  • To describe a straightforward method for fabricating and utilizing this dental jig.

Main Methods:

  • A universal jig is fabricated using an autopolymerizing resin mold based on a wax model.
  • The jig is adjusted to the patient's upper incisors.
  • Patients perform lateral jaw movements to achieve muscular relaxation for centric relation recording.

    • The described method allows for the recording of centric relation.
    • Plaster bite registrations are obtained, suitable for programming semi-adjustable articulators.
    • The jig facilitates the capture of jaw movements, including lateral and protrusive excursions.

    Conclusions:

    • The universal jig provides a practical and effective tool for dental professionals.
    • This technique simplifies the process of obtaining accurate jaw relation records.
    • The method supports precise programming of semi-adjustable articulators, enhancing restorative dentistry outcomes.
