Occlusal Bite in Reconstructive Surgery of the Oral Cavity

In the context of oral cavity cancer surgery, free flap reconstruction is considered the standard procedure. However, mechanical trauma resulting from occlusion can lead to complications such as ulcers and necrosis. This case series investigates the application of custom-made occlusal splints in three patients undergoing free flap reconstruction for oral cavity squamous cell carcinoma, with the aim of preventing complications and supporting rehabilitation. This retrospective case series comprises three patients who underwent free flap reconstruction at a tertiary care referral hospital. Each patient received a preoperative maxillofacial and orthodontic assessment, followed by the application of a custom-made occlusal splint immediately postoperatively to protect the flap and facilitate rehabilitation. Reconstructing the oral cavity presents significant challenges due to its intricate anatomy and the associated risks of flap failure and infections. The use of custom-made splints has demonstrated potential in mitigating occlusal trauma and facilitating recovery. Despite their promise, the application of custom-made oral splints remains insufficiently explored. Further research is needed to assess their potential in reducing complications and improving recovery outcomes. It is essential to validate their efficacy, optimize their usage, and integrate them into clinical guidelines for oral cavity reconstruction.
