Torque placed by dentists on prefabricated threaded posts.

Thirty-one dentists were tested relative to the optimal and maximum amount of torque they could deliver to posts in teeth. The mean for the optimal amount of torque was 15.55 ounce-inches, and the mean for the maximum amount of torque was 35.29 ounce-inches. Female dentists showed a statistically significantly lower mean difference of 24.5 ounce-inches on the maximum torque test.

A technique for fabrication of polydimethylsiloxane-acrylic resin obturators.

A flexible silicone obturator is an alternative to the acrylic resin obturator. It can be useful for patients with severe trismus who cannot insert a large prosthesis, as the flexibility of the hollow silicone section allows easy placement and removal (Fig. 9). Other patients cannot tolerate an unyielding substance against sensitive nasal tissues. Silicone can provide the necessary comfort without compromising retention. Silicone obturator sections can often be modified when further surgery is needed and result in a savings of time and expense (Fig. 10). For patients who can be reevaluated only twice a year, several silicone obturator sections can be made initially. One can be used while another is being cleaned or duplicated.

Prosthodontic management of postsurgical soft tissue deformities associated with marginal mandibulectomy. Part I: Loss of the vestibule.

1. Marginal mandibulectomy patients with a postoperative obliteration of the vestibule were treated prosthodontically in accordance with the "denture space" concept. 2. All patients presented displayed adequate form and function with the prostheses during a period ranging from 2 to 6 years without being subjected to preprosthetic surgery. 3. The most important factor when considering prosthesis stability is the interrelationship between form and function of the orofacial structures rather than the mechanical factors of maximal bone coverage by the prosthesis.

Mucormycosis in leukemia.

Rhinocerebral mucormycosis is a virulent, rapidly progressive, potentially fatal illness which demands early diagnosis and aggressive medical and possible surgical therapy. Although most commonly reported in persons with poorly controlled diabetes, it may occur in other immunosuppressed hosts. In persons with leukemia the disease has been uniformly fatal. A well-documented case of fatal rhinocerebral mucormycosis in a leukemic patient is presented to illustrate the diagnostic and therapeutic dilemmas often faced. A review of the 233 cases thus far reported in the literature is used as a spring-board for a discussion of the pathogenesis, diagnosis, and management of this disease.

Fabricating a shoulder somatoprosthesis.

A technique for the fabrication of a shoulder prosthesis has been described. The prosthesis has proven to be an effective means of rehabilitating a patient following an intrascapulothoracic amputation. The patient may once again wear clothing without having it adjusted to conform to the defect. Such rehabilitation has been of great psychologic value for patients and their families as well. The impression and processing procedures are effective for the fabrication of a shoulder prosthesis. The principles of this technique may be applied to the fabrication of other large somatoprostheses.

A flexible moulage for the fabrication of an orbital prosthesis.

A technique is disucssed by which a flexible three-piece moulage may be fabricated. This procedure is a useful aid in the modeling of an orbital prosthesis. It permits the continued transfer of a wax pattern from the moulage to the patient utilizing the tissue undercuts for the retention and stabilization of the pattern. The critical task of properly positioning the ocular prosthesis is simplified by the increased stability of the entire pattern. This is of the utmost importance since even a slight error in the alignment of the eye can entirely negate the effect of an otherwise accurate prosthesis. In addition, the retention of the wax pattern simplifies the carving procedure, and accurate detail is easily secured. The acrylic resin surface on which the final silicone prosthesis is cured has proven to be accurate. Well-adapted, thin margins of the facial prosthesis have been consistently obtained.

Preservation of occlusal vertical dimension in overdentures.

The preextraction record is used to reestablish the occlusal vertical dimension in immediate and in later overdentures. A colored dot on the denture can be used to verify the occlusal vertical dimension after the dentures have been inserted.
