Interim Maxillary Obturator Rehabilitation of an Aramany Class II Defect Following Resection for Oral Squamous Cell Carcinoma: A Case Report

Abstract

Oral squamous cell carcinoma frequently necessitates maxillary surgical resection, resulting in defects that compromise speech, mastication, and facial esthetics. Aramany Class II defects, characterized by unilateral maxillary loss posterior to the canine, present unique challenges for prosthodontic rehabilitation. This report describes the rehabilitation of an Aramany Class II maxillary defect using an interim obturator in a patient following oncologic surgery. The prosthesis was designed to re-establish oronasal separation, preserve arch form, and restore essential oral functions during the healing phase. Clinical procedures included careful impression making, appropriate design planning, and selection of suitable materials for fabrication. The interim obturator provided immediate functional benefits, significantly improving speech intelligibility, mastication, and the patient’s psychological comfort. Adaptation to the prosthesis was smooth, and follow-up assessments demonstrated stable performance and enhanced quality of life. This case underscores the critical role of interim obturators in early postoperative rehabilitation, emphasizing the need for a well-constructed prosthesis tailored to the specific defect classification. Early prosthodontic intervention facilitates functional recovery, prevents complications, and supports seamless progression toward definitive prosthetic management in patients with maxillary defects following OSCC resection.
