    Therefore, the use of maxillofacial prosthesis can bring good cosmetic and functional results; however, to perform this surgery can be a challenge to the professional. Obturator prostheses must fulfil certain functions such as facilitating food, protect wound or keep the defective area clean, increase trauma healing, help remodelling and rebuilding of palatine contour, promote speech and improve aesthetics25–29 (Figures 1, 2 and 3). The retention of an obturator depends on factors such as direct or indirect retention promoted by the remaining teeth, defect size, tissue retention available around the cavity and development of muscular control.30

    Relevant among these are (1) the need for a rigid major connector; (2) guide planes and other components that facilitate stability and bracing; (3) a design that maximizes support; (4) rests that place supporting forces along the long axis of the abutment tooth; (5) direct retainers that are passive at rest and provide adequate resistance to dislodgment without overloading the abutment teeth; and (6) control of the occlusal plane that opposes the defect, especially when it involves natural teeth. In addition, many unique considerations involved in the design are provided by the nature of the problem and the treatment required.2-4 Among these are (1) the location and size of the defect, especially as it relates to the remaining teeth; (2) the importance of the abutment tooth adjacent to the defect, which is critical to the support and retention of the obturator prosthesis; (3) the usefulness of the lateral scar band, which flexes to allow insertion of the prosthesis but tends to resist its displacement; and (4) the use of the surveyor to examine the defect for the purpose of locating and preserving useful undercuts or eliminating undesirable undercuts.
