title: The trial denture.
abstract: 1. Many difficult situations can be avoided if the dentist keeps constantly aware of the physiologic, the psychologic, and the artistic factors involved in the construction of dentures, whether they be partial or complete. 2. No one would think of buying an automobile without getting adequate instruction in how to drive; neither should a patient expect to wear artifical restorations without training and practice. 3. The dentist at the try-in should check: a. The bases for fit and extension. b. Thin labial flange at frenum area. c. Posterior palatal seal and length of upper. d. Posterior tooth poisition for height of plane, relation of plane to alatragus line, tongue room, and ridge relation. e. Anterior tooth position for lip support, length, and relation to lower lip. f. Entire setup for vertical dimension of the face, test balance and simultaneous tooth contacts in all desired positions. If discrepancies exist between the articulator and the mouth, make new jaw relation records. g. Check palatal contour and incisor positions in speaking. "F" and "V" sounds to test the upper incisor, sibilant sounds for vertical dimension and lower-to-upper incisal relationships. h. Wax-up for support and proper external form. If tori exist on upper or lower, be sure there is sufficient thickness to allow relief later on. i. Be sure to repeat and continue instruction of the patient in his understanding and handling of the new dentures. Now, in addition to all these checks to dentist makes, he must constantly anticipate the thoughts and attitudes of the patient and interpret them for better rapport and ultimate patient understanding. No stage in complete dentures is anticipated with such mixed emotions as is the try-in. No stage is so significant to the future success or failure of the patient to take dentures in his stride. No stage has so much potential for making the person happy or sinking him into the depths of despair. The return of self-confidence, the pride in appearance, the sparkle and drive that return to a patient when the restorations are enthusiastically accepted are a wonderful reward for dentistry well done.
