I took some time this past weekend to record a wide variety of dental procedures in order to better educate my patients. While editing the videos, I came to the realization that some of these videos can be used as a visual tool to help incoming dental students prepare teeth.

The video above illustrates an anterior tooth crown preparation. The use of depth cuts gives us a predictable way to achieve adequate reduction without over preparing a tooth. In the aesthetic zone, crown margins are typically placed equigingival/subgingival. Depth cuts & margin placement are ultimately dependent upon the color, contour & shape of the final restoration. For instance, a deeply discolored tooth that is dark from the gum line to the tip of the crown would need larger facial depth cuts as well as a subgingival margin in order to mask the deep discoloration for years on end. Many other factors also dictate the design of these preparations.

Dentists use a variety of different drills while cutting the teeth. Some of the dental drills are thin while others are tapered in a manner that leaves a clean crown preparation. Please feel free to message me with any questions!
