Review of Previous Module

Review topics from the previous module to confirm understanding prior to presenting new material.

Module Overview

Prosthodontics is the specialty concerned with replacement of teeth and missing or deformed oral structures. The accuracy of crowns, inlays, bridges, or dentures, and therefore the dental health of the patient, depends on the physical properties of the materials involved. The success of these prosthesis also rests with dental personnel who manipulate the materials and equipment during the process of creating the prosthesis. Dental laboratory technicians are partners with dental office personnel in the endeavor for maximum service for the patient. Strict attention to detail, and knowledge of materials used, are essential for dental assistants in order to aid in this process of fabricating oral structures.

Section 1: Fixed Prosthodontics

Section Overview

A fixed prosthesis is cemented permanently in place in the patient’s mouth, and if cared for properly by the patient, is designed to last a lifetime. It is a restoration that replaces missing tooth structure, improves mastication, prevents drifting of teeth, and promotes better oral health. The dental assistant’s meticulous responsibilities at each phase of the procedure contribute to the success of the final product. There are many steps involved and each one is vital to the ideal end result.

Part A: Types of Fixed Prosthetics

Overview

This part examines the various permanent fixed prostheses and materials used to restore missing tooth structure. Each requires a certain amount of tooth reduction by the dentist, and is an investment for the patient in their oral health. They are designed to provide maximum chewing efficiency and a lifetime of service. These restorations are prepared outside of the patient’s mouth, in a dental lab, and therefore are called indirect prosthetics. Dental assistants need to understand the various types of fixed prostheses and how they are fabricated, in order to support the dentist, as well as to be able to educate the patient regarding choices to improve the patient’s dentition.

Initial Questions and Activities

1. Is there anyone here who has a permanent crown or bridge? If not, what do you

think a patient might experience if they were to have a permanent crown or bridge?

There will be various answers depending on learners’ experiences. Ask what they remember about having impressions done and wearing a temporary restoration while the permanent prosthesis was being made. Remind learners that relating to the patient’s experience will help them be more caring dental assistants.

q  Porcelain Veneer Set Up (Part A, Objectives 2-5). Goal: To have learners set up for and understand Porcelain Veneer procedures. Instructor should ensure enough materials and supplies are available for learners and place them into teams. Learners should be graded on the procedure steps as outlined on pg. ____, Chapter ____(Phinney & Halstead). Learner workbooks contain check off sheets that can be utilized. Depending on supplies available, grading may include verbal explanation of certain steps, by the learners to the evaluator. Instructor should allow enough time for learners to practice steps before evaluating. The instructor should be the operator during testing and grading of this procedure.

[Insert In-Class Dis Ques icon] In-Class Discussion

1. Describe a good impression of a patient’s arch?

A good impression is an accurate negative reproduction of a persons teeth and surrounding tissues.

2. What would happen if not enough material is used for the impression?

The impression may not acquire enough of all oral structures necessary, if there isn’t enough material mixed, loaded into the tray, and then placed properly in the patient’s mouth.

3. What could happen if too much material is used for an impression?

This could cause the patient to gag.
