Surgical resection of a maxillary tumor often creates a large postoperative defect. Factors that affect the prognosis for successful, conventional prosthetic management of maxillary defects are the presence of teeth, amount of remaining support areas, and defect characteristics such as size, location, access, contour and available undercuts.
Aim: The aim of the described clinical case is to monitor the role which the prosthetic construction has in restoring the nutrition, speech and appearance of a patient with partial maxillectomy.
Materials and methods: For restoration in a 39-year old patient with partial maxillectomy and remaining 21, 22, 23 and 28 teeth, a bridge construction and hollow bulb model-cast obturator were fabricated. After preparing the teeth and tamponing the defect with gauze, a dual phase impression with Elite HD Putty and Elite HD Regular additive silicon was taken. The bridge construction was fixated with ICem dual-curing cement. The impression for the prosthetic’s model cast skeleton was taken with Phase plus irreversible hydrocolloid impression material. The model cast hollow bulb prosthesis following the resection was finished with Meliodent HC heat cure acrylic resin with a low level of residual monomer.
Results: The plan for fabricating a definitive postresection prosthesis that was set up and fulfilled, lead to a successful restoration of the impaired speech and masticatory function and helped restore the patient’s appearance and social contacts.
Conclusion: The application of prosthetic methods of treatment in patients with partial maxillectomy allows for a successful restoration of the impaired functions.
