Critical factors in selecting removable prostheses.

Preservation of as many natural teeth as possible should be the goal of conscientious dentists. However, occasionally, the sacrifice of some sound natural teeth may be indicated for partially edentulous patients to provide them with the most functional and esthetic masticatory apparatus. Selection of the proper prosthetic service is one of the most critical value judgments made by dentists. No matter how skillfully the wrong treatment is accomplished, it is still the wrong treatment. It is important, therefore, that all relevant data be gathered so that the best clinical judgment can be brought to bear in the decision-making process.

Basic wax contouring for complete dentures.

The form and contour of the polished surface of the denture base is an important factor in the appearance and function of complete dentures. It is the responsibility of the dentist to insure that the dental laboratory technician reproduces the proper anatomic contour of the denture base. With attention to details in the final wax-up, the finishing procedures will be minimal. The use of high shine is all that is needed to polish. If anatomy is lost in the investing procedure, and it is necessary to recarve it with acrylic resin burs, then it will be necessary to use both coarse and fine pumice and high shine to complete the dentures (Figs. 15 to 17). When one applies these basic principles, a denture surface is produced that will be both refreshing and natural in appearance and aid in the stability of the dentures in function. To our patients who are contemplating prosthodontic replacements, it should remove the fear of having to submit to accepting an unnatural restoration.

Alveolar bone loss in overdentures: a 5-year study.

The results of a 5-year clinical study show that patients treated with complete maxillary dentures and mandibular overdentures demonstrate less vertical alveolar bone reduction than patients with complete maxillary and mandibular dentures.

One-step border molding of complete denture impressions using a polyether impression material.

A technique has been described which uses a polyether impression material for border molding of complete denture impressions. It has the following advantages: 1. There is simultaneous molding of all borders of either the maxillary or mandibular impression. 2. Border molding can be accomplished with one insertion of the tray. 3. Functional movements performed by the patient are used in border molding. 4. The technique is easily mastered.

Effect of a denture adhesive on complete denture dislodgement during mastication.

A method of evaluating the denture stabilizing effects of a denture adhesive by means of counting denture dislodgements during the eating of a standardized portion of a test food is described. A reduction in the number of such dislodgements after application of a denture adhesive, as compared to eating the same food without adhesive applied to the denture, was used as a measure of adhesive effectiveness. Subject responses to a number of denture-performance satisfaction parameters were also obtained. With a test adhesive, significant reductions in dislodgement were found using steak, taffy-apple, a hard-roll sandwich, and celery as test foods among 16 subjects with dentures that fit well. Analysis of subjective evaluations indicated that the test adhesive was perceived as having effected: (1) improved chewing ability, (2) reduced denture wobble, (3) improved confidence, (4) increased comfort, and (5) reduced amount of food particles collecting under the denture, all to a significant degree (p < .01). It is suggested that additional data from controlled clinical studies are needed to allow proper assessment of the usefulness and possible abuse effects of denture adhesive products. This method, and the resulting data, are offered as a stimulus to the end.

Prosthodontic and speech rehabilitation after partial and complete glossectomy.

A multidisciplinary approach to the rehabilitation of four glossectomy patients has been presented. Points emphasized were the anatomic defects, their effect on the three oral functions of mastication, deglutition, and speech, and the various prosthetic modifications found most effective to restore the impaired oral functions.

Clinical evaluation of complete denture therapy: examiner consistency.

Criteria were developed to clinically evaluate denture base stability and retention. Six completely edentulous subjects participated in the study. Each patient was treated with two sets of complete dentures. Six prosthodontists who were not involved in the patients' treatment evaluated the stability and retention of each denture at the delivery appointment and weekly for the following 2 weeks by means of criteria in a standardized form. Evaluation of stability and retention for maxillary and mandibular complete dentures worn during weeks 1 and 2 were compared with the evaluations made at the delivery appointment for each denture. In tabulation of the data, the criteria considered reliable were mandibular denture retention, maxillary denture retention evaluated unilaterally, and maxillary denture stability. In each category most examiners rated the judgments the same or better when compared with the delivery appointment data for each patient.

Pressure indicators for removable prosthodontics.

P.I.P. and Coltene pressure spot indicator were tested on the same 30 sets of complete maxillary and mandibular dentures and on two maxillary dentures against natural dentition. They were tested at delivery for pressure spots, but adjustments were not made. They were tested again after 24 hours to visualize and compare actual pressure spots. Half the dentures were adjusted according to P.I.P. and half according to Coltene pressure spot indicator. The patients were recalled after 1 week to determine if they were free from discomfort. The P.I.P. showed a greater clinical correlation of predictable to actual pressure spots and enabled the investigators to spare more patients from post-delivery discomfort.

Diagnosing functional complete denture fractures.

Many factors can contribute to the fracture of complete dentures. This article has identified some of these factors and presented some methods that can greatly reduce or eliminate functional complete denture base fractures when used with a thorough diagnosis and treatment plan.

Vertical dimension record: a three dimensional phenomenon. Part I.

This article presented data on 92 edentulous patients in the age group of 54 to 84 years. The data describe the changes in vertical dimension of rest observed under different clinical conditions associated with the treatment procedures for construction of complete dentures.
