Articulator modification for maxillofacial prosthesis.

G J Hadeed, R H Sprigg

    The Journal of Prosthetic Dentistry
    |August 1, 1980
    PubMed
    Summary

    A modified face-bow technique simplifies maxillofacial prosthesis construction by adjusting condylar inclination to compensate for maxillary cast positioning. This innovation makes fabricating dental prostheses easier for clinicians and technicians.

    Area of Science:

    • Maxillofacial prosthodontics
    • Dental laboratory technology
    • Biomechanical engineering in dentistry

    Background:

    • Maxillofacial prosthesis construction traditionally presents challenges in accurately relating the maxillary cast to the occlusal plane.
    • Existing methods may require expensive specialized equipment or complex adjustments.

    Purpose of the Study:

    • To describe a modification enabling face-bow use in maxillofacial prosthesis fabrication.
    • To offer a cost-effective solution by adapting existing articulators.

    Main Methods:

    • Modification of an existing dental articulator to incorporate a face-bow.
    • Adjustment of condylar inclination to compensate for inferiorly positioned maxillary casts.
    • Maintaining the correct relationship to the occlusal plane.

    Main Results:

    • The described modification allows for the use of a face-bow in maxillofacial prosthesis construction.
    • Inferior maxillary cast positioning can be compensated by increasing condylar inclination.
    • Versatility is achieved by modifying existing articulators, avoiding high costs.

    Conclusions:

    • This modification simplifies the fabrication process for maxillofacial prostheses.
    • It offers a practical and economical approach for dental laboratory technicians and dentists.
    • While not solving all challenges, it improves the ease of prosthesis construction.
