Summary

The Dynasplint Trismus System (DTS) effectively improved jaw range of motion in patients with trismus. This low-load, prolonged stretch modality helped patients regain function after radiation, surgery, dental work, or stroke.

Background:

Trismus, characterized by limited jaw opening, can result from radiation therapy, dental procedures, oral surgery, or neurological conditions like stroke.
The Dynasplint Trismus System (DTS) is a device designed to treat trismus by applying prolonged, low-load stretching.
Evaluating the efficacy of the DTS is crucial for improving patient outcomes and quality of life.

Purpose of the Study:

To retrospectively assess the effectiveness of the Dynasplint Trismus System (DTS) in patients diagnosed with trismus.
To determine if the DTS can improve maximal interincisal distance in patients with trismus from various causes.

Main Methods:

A retrospective review of 48 patient histories treated between 2006 and 2007 was conducted.
Patients were categorized into four groups: radiation therapy, dental treatment, oral surgery, and stroke.
The DTS was prescribed for patients with a maximal interincisal distance below 40 mm, with usage of 20-30 minutes, three times daily.

Main Results:

A statistically significant improvement in maximal interincisal distance was observed across all patient groups (P < 0.0001).
No significant difference in treatment efficacy was found between the different etiological groups (P = 0.374).

Conclusions:

The biomechanical approach of the DTS, utilizing low-load, prolonged-duration stretch, was effective in reducing jaw contracture.
The system successfully improved range of motion, enabling patients to restore essential functions like eating, hygiene, and speech.
The DTS offers a viable therapeutic option for managing trismus across diverse patient populations.
