# Assist with Crown and Bridge Procedure

Dental Assisting

This module explains the dental assistant's role in understanding and performing a crown and bridge procedure.

* * *

This module provides knowledge about crown and bridge procedures. The four main stages of crown and bridge fabrication are covered here, including: preliminary impression, preparation of the tooth, final impression and/or scan, and provisional coverage. The dental assistant plays a crucial role in aiding the dentist to ensure a safe and successful procedure. This includes preparing necessary materials, ensuring all equipment is properly functioning, efficiently handing off to the dentist the needed tools to complete the procedure, and ensuring the patient is comfortable throughout the procedure. Including both Learn and Test modes, the online simulator offers clinical scenarios that test your ability to assist with a crown and bridge procedure. Practice the steps of the procedures online as often as you want, until you feel confident.

**You'll learn**

- how the tooth is prepared for a crown and bridge procedure
- the various methods for impressioning
- the different forms of material used during a crown and bridge procedure
- the steps for placing a gingival retraction cord
- provisional coverage fabrication and cementation
- much more (see Content Details for more specific information)

The SIMTICS modules are all easy to use and web-based. This means they are available at any time as long as the learner has an internet connection. No special hardware or other equipment is required, other than a computer mouse for use in the simulations. Each of the SIMTICS modules covers one specific procedure or topic in detail. Each module contains:

- an online simulation (available in Learn and Test modes)
- descriptive text, which explains exactly how to perform that particular procedure including key terms and hyperlinks to references
- 2D images and a 3D model of applied anatomy for that particular topic
- a step by step video demonstration by an expert
- a quiz
- a personal logbook that keeps track of all the modules the learner has studied and how long
