An adhesive technique for small anterior fixed partial dentures.

A technique for the fabrication of a resin anterior fixed partial denture of intermediate length has been described. This type of device offers an inexpensive, quick treatment for selected patients with two adjacent missing anterior teeth. The technique allows the postponement of a definitive treatment to a more favorable time. The total treatment can be completed in two relatively short appointments.

Five-year cephalometric study of mandibular ridge resorption with different posterior occlusal forms. Part I. Denture construction and initial comparison.

The average 5 year reduction of the occluding vertical dimension (nasion to menton) for 45 patients was 3.2mm. (2.8 mm. for the anatomic group, 3.2 mm. for the semianatomic group, and 3.6 mm. for the nonanatomic group, each constituting 15 patients). Mandibular physiologic resting face height became foreshortened on the average only one third as much as the morphologic centric occlusion face height. Tabulation of adjustments for sore spots indicated that: the fewest postinsertion appointments were required for the anatomic group of patients; three fourths of 604 denture base alterations were on lower dentures; for upper and lower denture base alterations, one third were made on the borders and two thirds, on the basal seat; one sixth of all alterations were made at routine recall examinations; the fewest upper denture base alterations were for the nonanatomic patients; and the fewest adjustments of the lower denture base on the tissue surface and on the borders were done for the anatomic group of patients. This investigation has been underway for 18 years, and several more re

Lingualized occlusion for removable prosthodontics.

Lingualized occlusion provides a useful combination of several occlusal concepts. Many advantages of anatomic and nonanatomic occlusions are retained. Adjustment to compensate for minor changes in vertical and centric relation is readily accomplished. Satisfactory occlusion is easily obtained, and balanced occlusion can be accomplished. The lingualized occlusal concept is not a panacea, and all other procedures still must be carefully executed.

Composite resin repair of porcelain denture teeth.

An effective temporary repair of fractured poreclain denture teeth involves abrasive treatment of the fractured tooth surface followed by a composite resin buildup. This study has demonstrated that the best potential retention of the composite buildup can be obtained through abrasive treatment by a course diamond stone.

Prosthodontic techniques and the timing of complete denture procedures--a survey.

This survey has attempted to show some of the differences in techniques and materials used by three groups of dentists involved in prosthodontic work in the United States. Some contrasting features between dentistry performed by the NHS and that in the United States have been illustrated, but fair comparisons between the two systems could not be made because of the basic difference in the number of patients and completed treatments and the fee schedules.

A temporary space maintainer using acrylic resin teeth and a composite resin.

A one-session technique for preparing a temporary space maintainer has been described. The technique consists of attaching an acrylic resin pontic to etched surfaces of natural adjacent teeth by means of a composite resin. The main advantages of this technique are elimination of premature tooth preparation, good esthetics, fair strength, low cost, and rapid completion of the restoration without the need of a dental laboratory.

Photoelastic comparison of posterior denture occlusions.

The development of stress patterns was observed within a photoelastic model under complete mandidular dentures. Characteristic stress patterns were related to type of tooth material. Plastic teeth transmitted less force than porcelain teeth. Cusp teeth induced concentrated regions of force within the model that contrasted with the uniform distribution of force observed with flat teeth. The dentist should be aware of the biomechanical problems associated with any posterior denture occlusion in relation to the residual alveolar ridge.

Occlusal considerations for the partial mandibulectomy patient.

The occlusal scheme fabricated for a patient with a mandibular defect varies extensively from patient to patient, with some limitations in occlusal efficiency. Some patients may expect little or no occlusal efficiency if the defect is large and if the associated mandibular deviation and the lack of muscle control and excessive. If the continuity of the mandible can be restored by secondary surgical management (Fig. 10, A), most of the problems of the discontinuity defect can be resolved. Whether the teeth in the region of the defect are replaced or not may be dependent on other factors, but the mandible can be treated as a stable entity within itself, and the prosthodontic approach can be similar to that discussed for the continuity defect (Fig. 10, B). The mandibulectomy patient is difficult to manage because the prosthodontist is limited in his ability to provide a reasonable and practical occlusal scheme. However, these patients need the definitive clinical and psychological support of the prosthodontist. Most patients recognize the limitations of their rehabilitation and are appreciative of the prosthodontic therapy that enhances their rehabilitative progress.

Geometric analysis of tooth arrangement.

Based on the principles of solid geometry and projection geometry, a mathematical system can be used to indicate any positional change of tooth arrangement on a trial denture. To summarize: 1. When you move a tooth, you have to know whether you move the tooth toward the patient's left side or right side (x), upward or downward (y), anteriorly or posteriorly (z), and how many millimeters in each component dimension. If rotatory movements are involved, you must know whether the tooth rotates around the mesiodistal axis (+/-M), around the faciolingual axis (+/-F), or around the gingivo-occlusal axis (+/-G). You must know the degrees of rotation around each of the component axes and whether the movement is clockwise or counterclockwise. Most students will easily follow this systemic approach and readily understand the complexity of the problem.

A study of the relationship of the dental midline to the facial median line.

This report presents the results of an original investigation designed to determine (1) the prevalence in the natural dentition of a maxillary midline located in the exact middle of the mouth using the philtrum as the most reliable guide and (2) the percentage of people in whom the maxillary and mandibular midlines precisely coincide with each other. Results indicate that the midline is situated in the exact middle of the mouth in approximately 70% of people and that the maxillary and mandibular midlines fail to coincide in almost three fourths of the population.
