Bite mark impressions: a review of techniques and materials.

Many techniques are described in the literature for use in making impressions of bite mark indentations. A representative technique is presented in detail. Several types of dental materials common to many impression techniques are reviewed with regard to their accuracy, ease of use, and dimensional stability over time. Adherence of materials and a model pouring technique are also discussed.

Current status of Geriatric Dentistry Educational Activities in U.S. dental schools.

The current status of Geriatric Dentistry Educational Activities (GDEA) in U.S. dental schools is reported in this survey. Data were collected regarding faculty involvement in geriatric programs, didactic and clinical academic curricula, and other aspects of the ongoing activities in schools. Data were reported by 50 (88 percent) of the nation's 57 dental schools in continuing operation. Forty-two schools reported discrete GDEA at the time of the study. Seven of these schools had a formal division or department of geriatric dentistry. The survey indicated that educational qualification of GDEA coordinators had risen significantly in recent years. The mean number of didactic hours (29) of instruction in geriatric education available to students has also risen. Curriculum time and financial considerations were the primary obstacles to expansion of clinical geriatric activities. With the current economic constraints in dental education, present GDEA levels are unlikely to expand in the foreseeable future, unless governmental or private agencies recognize the importance of developing GDEA and increase their support.

Tissue displacement methods in fixed prosthodontics.

The various methods to accomplish gingival displacement have been described. The techniques have been noted and their relative advantages and disadvantages summarized. The practicing dentist can use this review to make better informed decisions regarding the method he or she chooses for the treatment of a particular patient.

Interalar width as a guide in denture tooth selection.

This study was undertaken to determine the relationship of the IAW, measured between at the widest dimension of the alae of the nose, and two other measurements of maxillary anterior teeth. The other measurements, both of which are significant in the selection and arrangement of artificial teeth used in complete dentures, were the ICTW and the ARCD measured from the distal surface of the maxillary canine on one side of the arch to the distal surface of the canine on the opposite side of the arch. No distinction was made between either the sex or the age of the subjects. The mean ICTW of 35.35 mm was 3% greater than the mean IAW of 34.28 mm. The mean ARCD of 44.85 mm was 31% greater than the mean IAW of 34.28 mm. This mean ARCD compares favorably (less than 1 mm difference) with a constructed ARCD of 45.8 mm from a tooth dimension study by Shillingburg et al. The ARCD was 44.85 mm. This measurement had not been made in the previous study examining the relationship of interalar distance to ICTW. When the IAW was plotted against the intercanine cusp tip width, a fairly strong correlation coefficient of 0.413 was exhibited. A weaker but definite correlation coefficient of 0.217 was observed when the interalar width plotted against the circumferential arc distance from distal surface to distal surface of the maxillary canines.

Impression material thickness in stock and custom trays.

This study did not examine the accuracy of the resultant impressions. Rather, the impression material thickness in impressions made using both the highly advocated custom acrylic resin tray and in the highly used manufactured stock tray was examined. Comparison between the material thickness at the prepared tooth area revealed a mean difference in material thickness of less than 1 mm. The question of the significance of this difference remains to be answered. If the difference is not significant in the success of the impression and the resultant casting, then there are several advantages in using the manufactured stock tray; the first is economy. The average cost of a custom acrylic full arch impression tray is $3.65, compared with an average cost of slightly over $0.30 for the stock tray. The second advantage is the convenience factor. Making a custom tray requires planning, study models, laboratory time, curing interval, and finishing time. In contrast, the stock tray can be selected, adapted, and used in a single visit for both anticipated and unanticipated situations. If the difference in material thickness is significant, the custom tray is indicated. However, attention to detail in making and inserting the tray in the mouth must be observed to maximize the benefits of the custom tray.
