An extensive intraoral maxillofacial prosthesis presents challenges to the clinician in many ways. The problems encountered
may include support and retention of the prosthesis. These problems arise due to unfavorable anatomical configuration of
the defect. This unfavorable configuration may prompt the clinician to device alternate /additional means of support and
retention. The aim of this article is to review these additional means of support and retention for the maxillary obturator
prosthesis. The obturator prosthesis is commonly used as an effective means for rehabilitating hemi maxillectomy cases. In
cases of large maxillary defects, movement of the obturator prosthesis is inevitable and requires indirect retention to limit
the rotation of the prosthesis. The goal of prosthodontics is rehabilitation of missing oral and extraoral structures along with
restoration of the normal functions of mastication, speech, swallowing, appearance, and so on. Malignancies are common
in the oral region, which are treated through surgical intervention. Surgical intervention creates communication between
the oral cavity, nasal cavity, and maxillary sinus. In such cases, it is very difficult for the patient to perform various normal
functions like mastication, swallowing, speaking, and so on. Prosthodontic rehabilitation with obturator prosthesis restores
the missing structures and acts as a barrier between the communication among the various cavities.
