Apparatus for simulating extraction forces.

R Lehtinen, T Ojala

    International Journal of Oral and Maxillofacial Surgery
    |August 1, 1986

    Summary

    Dental students practiced simulated tooth extractions using a phantom skull and forceps. Measured moments were lower than real extractions, highlighting the need for supervised training in proper technique.

    Area of Science:

    • Dental education
    • Biomechanics of extraction

    Background:

    • Simulated training is crucial for dental students before patient procedures.
    • Understanding forces and moments in tooth extraction is essential for safe practice.

    Purpose of the Study:

    • To evaluate the use of a phantom skull simulator for teaching tooth extraction.
    • To measure extraction forces and moments during simulated procedures.

    Main Methods:

    • Utilized a phantom skull, extraction forceps, and a mean value indicator.
    • Measured rocking and twisting moments using strain gauges during simulated extractions.
    • Dental students performed simulated extractions on various teeth.

    Main Results:

    • Measured moments during simulated extractions were significantly lower than those required for actual patient extractions.
    • The simulator provided a platform to assess and quantify extraction forces and moments.

    Conclusions:

    • Simulated extractions using this method offer a safe learning environment for dental students.
    • Supervised instruction on correct forceps grips and extraction techniques is vital when using simulators.
