New physiotherapy device for interincisal mouth opening in oral submucous fibrosis patients: A pilot study

Abstract

Objectives: It is estimated that 0.2–0.5% of Indians suffer from oral submucous fibrosis. The states of Gujarat, Bihar, Madhya Pradesh, and Maharashtra are the most severely impacted by this illness. Antioxidants, effective physiotherapy exercises, and topical corticosteroid injections are among the treatment options available for oral submucous fibrosis (OSMF). Despite being widely used, there are few studies assessing the effectiveness and patient compliance of the conventionally used technique for physiotherapy in patients with OSMF, such as ice cream sticks, tapered screws, and Heister jaw opener. Material and Methods: A device for physical rehabilitation that may be used at home was made using 3D printing technology. Ten patients participated in a pilot study that was carried out. These patients participated in the device’s pilot testing to assess the mechanical features and its ability to improve interincisal mouth opening, comfort (pain and control), and enjoyment. Comfort [Pain, comfort, control] with device use, ease of use [Portability] and satisfaction with device use. Results: A statistically significant (P < 0.0006) improvement in the mean mouth opening of OSMF patients was shown by quantitative data. After 1 month of use, there was a 1.8 mm difference in mouth opening. This implies that the device worked well for these people. Based on feedback, the majority of patients reported that the device was comfortable, easy to use, and showed satisfaction with the device use. Conclusion: It was found that people with OSMF can open their mouth more with the use of a new physiotherapy device. In addition to pharmacological therapy, this pilot study needs more investigation with a bigger sample size and a randomized control trial. Considering that this method of managing OSMF seems to be effective.
