DLT 103 - Complete Dentures

1 Credits, 1 Contact Hours
1 lecture period 0 lab periods

Examination of the relationship between upper and lower dentures as interpreted on a functional articulator. Includes evaluation of preliminary impressions and fabrication of models, custom impression trays, evaluation of final impression and master model, baseplate fabrication, occlusion rims, articulation and mounting of working models, and prosthetic tooth selection. Also includes setting artificial denture teeth, processing the trial denture, finishing complete dentures, fabricating surgical templates, and denture repair and reline.

Prerequisite(s): DLT 101  and DLT 101LB , or concurrent enrollment.
Corequisite(s): DLT 103LB  
Information: Consent of program director is required before enrolling in this course.
