This study found that patients undergoing temporomandibular joint (TMJ) surgery achieved encouraging oral function, as measured by bite force. Post-surgery bite force measurements indicate good recovery of chewing strength and endurance.

Area of Science:

  • Oral and Maxillofacial Surgery
  • Biomedical Engineering
  • Dental Research

Background:

  • Temporomandibular joint (TMJ) disorders often necessitate surgical intervention.
  • Evaluating post-surgical oral function is crucial for patient outcomes.
  • Bite force measurement is a key indicator of masticatory performance.

Purpose of the Study:

  • To assess oral function in patients after TMJ surgery using bite force measurements.
  • To compare bite force between operated and non-operated sides.
  • To evaluate the recovery of masticatory function following discectomies and condylectomies.

Main Methods:

  • Bite force measurements were conducted on 30 patients post-TMJ surgery (27 discectomies, 3 condylectomies).
  • Follow-up averaged 2.5 years.

  • Measurements included mean bite force during chewing and maximal bite force and endurance.

    • Main Results:

    • Mean bite force during chewing was 125.3 N (right) and 128.8 N (left).
    • Maximal bite force averaged 362.5 N, with endurance at 32 seconds.
    • No significant differences were found between sides or operated/non-operated sites.

    Conclusions:

    • Post-TMJ surgery, patients demonstrate robust oral function as indicated by high bite force values.
    • The findings suggest successful recovery of masticatory capabilities after TMJ surgical procedures.
    • Bite force measurements provide encouraging data on oral function recovery post-surgery.
