Full Crown Module - Learner Level 1 - Tooth Preparation for Full Crown Restoration

Sep 27, 2026

Uploaded by Eliana

Full Crown Module - Learner Level 1 guides learners through preparing a single tooth (#30) in a simulated exercise to receive a full crown restoration. It explains how to set up articulated teeth on a Frasaco model, create impressions with alginate, pour microstone, and mount the articulator in a simulated patient. The module then covers clinical principles for preparation, including conservation, resistance, retention, durability, marginal integrity, periodontium preservation, and esthetic considerations. It details step-by-step occlusal reduction targeting 1.0 mm uniform reduction using depth grooves, verification methods, and rationale for different clearance needs.

Estimated Completion Time: 6 hours | I. Module Information In level 1 of the Full Crown Module, we are going to apply all the principles of preparing tooth to receive a full crown restoration. You will be guided with the step by step procedures in preparing tooth \#30 (Fig. 1) that is going to be restored with a Full Gold Crown (FGC) (Fig. 2) . An extension of the exercise is also included for further practice and efficiency. Fig. 1. Pre-operative photo of tooth \#30 Fig. 2. Prepared tooth \#30 to receive FGC restoration II. Setting up of the Articulated Teeth Since this is a simulated exercise, tooth preparation should be done on a Frasaco ® Model mounted on the simulator. 1. Get a typhodont tooth \# 30. 2. You may also start setting up for your extensions and mount teeth \# 12 and \#8 3. Screw it on the space provided. 4. Make an alginate impression and pour it with the microstone. 5. Mount the articulator in the simulated patient. 6. Prepare silicone putty matrices of the tooth and the adjacent teeth 7. Prepare your instruments (handpiece, burs and mouth mirrors, etc,) 8. Have the evaluation criteria with you. Full Crown Module: Learner Level 1 1 Ranier M. Adarve, DMD, MS, MHPE University of Minnesota School of Dentistry | Clinical Relevance | | --- | | As with any fixed prosthodontic procedure, you should always have a diagnostic cast to visualize your planned procedure. The silicone matrix will guide you during preparation as well as help you determine the adequacy of your tooth reduction. Take note that in some instances, silicone matrix may not be the best technique to use to evaluate your preparation. Other techniques, like using a vacuum-formed matrix may be more practical especially on teeth that are tilted, rotated or deviated from normal position. We will deal with these kinds of situation in the succeeding levels of the Full Crown Module. | III. Preparing Tooth for Full Crown Restoration In the succeeding steps, we will be reducing the tooth structure per tooth surface. Although the sequence of surface to be reduced may vary according to operator’s preference, our recommended steps would focus more on the goal(s) of each procedure and the amount of tooth structure to be reduced. As you begin your tooth preparation, read the full crown evaluation matrix to guide you in applying the principles of the tooth preparation. | Instructor’s Note | | --- | | Full Crown Preparation requires the understanding of the fundamental principles. As a review, these are:
a. Conservation of tooth structure
• Avoid weakening the tooth unnecessarily.
• Avoid compromising the pulp.
b. Resistance form
• Prevent dislodgment of the restoration by apical or obliquely-directed forces.
c. Retention form
• Prevent dislodgement of the restoration by forces along the path of insertion, including the long axis of the tooth
d. Structural durability.
• Provide enough space for the crown which is sufficiently thick to prevent fracture, distortion or perforation.
e. Marginal integrity
• Prepare a finish line to accommodate robust margin with close adaptation to minimize microleakage.
f. Preservation of the periodontium
• Shape the preparation such that the crown is not over contoured and its margin is accessible for optimal oral hygiene.
g. Esthetic Considerations
• Create sufficient space for esthetic veneers where indicated
Make sure these principles make sense to you for they will surely guide you in your procedures. If you need further explanations of these principles, don’t hesitate to ask your instructor. | Full Crown Module: Learner Level 1 2 Ranier M. Adarve, DMD, MS, MHPE University of Minnesota School of Dent

FAQs

What is the objective of the Full Crown Module at Learner Level 1?

To apply the principles of preparing a tooth to receive a full crown restoration, with guided step-by-step preparation of tooth #30 for a Full Gold Crown (FGC).

How do learners set up the articulated teeth for the simulated exercise?

Use a Frasaco model mounted on the simulator, obtain a typhodont tooth #30, mount extension teeth (#12 and #8) as needed, screw them in place, make an alginate impression, pour with microstone, mount the articulator, prepare silicone putty matrices, and prepare instruments and evaluation criteria.

What is the target occlusal reduction amount and how is it achieved?

The goal is 1.0 mm uniform reduction of the occlusal surface while following the tooth’s contour, accomplished with depth grooves and removal of islands of tooth structure between the grooves.
