A case is reported assessing the problems encountered after surgical resection of the maxilla. The use of a hollow box obturator and details of its construction are described. The importance of skin grafting of the maxillary defect and use of available anatomical undercuts to optimise support and retention of the obturator is stressed. By provision of a lightweight hollow obturator, the weight of the prosthesis is kept to a minimum, helping retention, and allowing good resonance during speech. Initially the patient was to be assessed for an implant retained prosthesis, however, a satisfactory conventional prosthesis met the functional and aesthetic needs of the patient and avoided the need for further surgery for placement of implants.
This clinical report presents a treatment procedure that makes immediate denture placement a more predictable and less stressful procedure. It provides greater control over the prosthodontic aspects of denture delivery by the restorative dentist, and the convenience of performing the placement procedures in a clean, blood-free environment. The delivery of the prosthesis is less traumatic because extractions and/or surgery are deferred. In addition, by the time the remaining roots are extracted, all denture adjustments will have been made and the patient will have accommodated to the prosthesis.
This article describes a procedure that uses the Ney MS (Minimal Space) intracoronal attachment as an interlock in a pontic. This procedure overcomes the disadvantages associated with the use of the intracoronal attachments, which are (1) excessive tooth reduction often required to place the attachment within the contour of the crown; (2) compromised embrasures, which result in oral hygiene and periodontal problems; and (3) poor esthetics.
