Technique for controlling the thickness of a facial prosthesis when an acrylic resin core is used.

A technique for evaluating the acrylic resin core before processing a silicone facial prosthesis is described. The technique involves the use of either irreversible hydrocolloid impression material or silicone to identify thin areas in the pattern. This simple yet effective procedure ensures adequate thickness and strength of the silicone prosthesis, which in turn decreases the amount of chair and laboratory time needed at the delivery appointment.

Mandible fragment fixation during reconstruction: the splint-and-plate technique.

One of the most popular methods of mandible fragment fixation is the precontoured reconstruction plate technique. Unfortunately, this method is not a reliable option when tumor distorts the mandibular contour or extends through the buccal cortex of the mandible. An alternative to the precontoured reconstruction plate is the splint-and-plate technique of mandible fragment fixation. An application of this appliance and method in 10 patients revealed the technique's advantages. The splint can be applied quickly and does not obstruct the ablative or reconstructive procedure. Further, the splint accurately keys the dentition and reliably maintains temporomandibular joint relationships. Finally, this technique provides a reference point to the exact position of the symphysis and angle when these landmarks have been resected.

An acrylic resin core for processing silicone facial prostheses.

A technique is presented for making an acrylic resin core for processing silicone facial prostheses. This technique ensures a durable core that can be used to make multiple prostheses. The core resists fungal growth during storage and creates a smooth, easily cleanable internal surface for a facial prosthesis. The core also permits a controllable thickness and therefore a lighter prosthesis.

A shade guide for acrylic resin facial prostheses.

The value and success of a well-fitting and anatomically correct prosthesis are compromised if the color does not match the adjoining tissue. Color and color science are reviewed to help develop a simplified acrylic resin shade guide to aid in fabricating acrylic resin facial prostheses. This guide will help the clinician obtain a good intrinsic shade and minimize extrinsic coloration.

A flasking technique for microwave processing of silicone prostheses.

Polyvinylchloride plumbing parts provide a readily available source of material to use in making facial prostheses. Inexpensive pipe fittings (end cap attachments and closet flanges) can be combined to provide a durable container for stone molds that can be tightened in a strong curing press. The entire unit can be cured in a microwave oven in 30 minutes.

Modified technique for preparing a polyurethane lining for facial prostheses.

A simplified technique for preparing, under a vacuum, a polyurethane lining for a facial prosthesis is described. A previously presented technique strengthened the prosthesis and allowed it to be attached with a water-based adhesive. This technique eliminates wrinkling, simplifies bonding, allows multiple linings to be made at the same time, conserves time and cost, and improves predictability of the results.

Extraoral retention of an obturator prosthesis.

In this study, a technique is described by which large obturators can be retained with an acrylic resin head plate. The technique entails attaching the prosthesis to an acrylic resin plate with a 2-mm-diameter wire and then attaching the plate to the patient's forehead with skin tape.

Multidisciplinary teamwork in the treatment and rehabilitation of the head and neck cancer patient.

The advantages of multidisciplinary treatment planning of head and neck cancer patients is described. Planning rehabilitation concurrently with curing the malignancy results in the most effective application of treatment modalities coordinated with rehabilitative care. Concentrated multidisciplinary treatment reduces post treatment morbidity by shortening recovery and rehabilitation time.

Rehabilitation of a patient with limited oral opening following glossectomy.

Rehabilitation of the glossectomy patient is one of the most difficult and challenging problems for the prosthodontist and speech pathologist. The tongue plays an important role in articulation, control of secretions, formation of a bolus, propulsion of the bolus toward the pharynx, clearing the palate, and initiation of the swallow reflex. This paper presents speech and prosthodontic considerations for a patient who underwent a glossectomy and had the additional problem of reduced oral opening.

Prosthodontic and surgical considerations for pediatric patients requiring maxillectomy.

The quality of treatment and rehabilitation for the head and neck cancer patient, especially the pediatric patient, has progressed markedly over the years due to the cooperation of specialists involved in the total care of the patient. Defects of the oral cavity caused by trauma or removal of malignant or benign tissue require special treatment considerations with the pediatric patient. Aside from radiation and chemotherapy, other forms of adjuvant therapy, such as physical therapy, and patient and family counseling, are needed for proper rehabilitation. In addition, oral hygiene is essential in the overall rehabilitative process. Pediatric dental, orthodontic, prosthodontic, and oral and maxillofacial surgery specialties become integrated in treating the pediatric patient. The concentrated multidisciplinary treatment reduces post-treatment morbidity by shortening recovery and immediate rehabilitation time and by providing long-term care during the critical growth period.

Rehabilitation of a midface defect with reconstructive surgery and facial prosthetics: a case report.

This paper reports a case in which reconstruction of a midface defect was accomplished by using microvascular surgery with free tissue transfer of the fibula for a 55-year-old man with squamous cell carcinoma in the nasal vestibule and nasal wall. This technique was developed and first used to reconstruct mandibular defects. Using a surgical template during the midface reconstruction can help the surgeon place the graft in a position that will complement the definitive facial prosthesis, as illustrated in this report.
