Conventional Prosthetic Rehabilitation of Maxillectomy Patient: Two-steps Impression Technique

Maxillary tissue defects can be treated surgically, prosthetically, or by both methods in order to obtain orofacial rehabilitation and defect obturation, thus improving oral function, speech, and esthetics. Treatment planning and successful obturation depend on the extent of the defect and the remaining hard tissue. Prosthetic rehabilitation of a patient with an acquired maxillary defect can be successfully achieved by obturator prosthesis. Precise obturation requires an accurate impression of the resection cavity, so a twostep impression technique was performed due to the limited possibility of mouth opening. First-step impression precisely showed all the intraoral structures but only the entrance of the resection cavity while the second step or definitive impression (material) was inserted into the patient’s mouth with the help of obturator metal base, serving as a tray, thus giving the opportunity to take the impression of the whole resection cavity. Afterwards, obturator prosthesis was completed by a conventional technique.
