Sectional Tray Approach for Cheek Bumper Prosthesis in a Patient with Oral Submucous Fibrosis

Oral submucous fibrosis is a precancerous condition commonly presenting with trismus due to fibrosis of the submucosal tissue in the oral cavity. In dentate individuals, postsurgical injury by teeth to oral mucosa can lead to ulceration and subsequent infection at the reconstructed site. In patients with reduced mouth opening induced by submucous fibrosis, the impression making procedure may be difficult to carry out due to reduced tissue resiliency and obliteration of vestibular spaces. In this case report, the fabrication of protective appliance in the form of cheek bumper in dentulous patients with sub mucous fibrosis, which play a dual role of both protecting the flap and assisting the healing process by utilising a sectional custom tray impression method has been described.
