Gallery: Biomimetics

Biomimetics seeks to mimic nature in both beauty and function. Below you will see some cases of simple biomimetic dentistry in our practice.

This patient had a broken bridge on the front three teeth. After bleaching, a new bridge was made to match the adjacent teeth and blend in smoothly with his function and appearance.

A large portion of this tooth had broken off leaving a significant portion missing. Rather than place a large crown and cover the entire tooth, a conservative onlay was prepared to blend in with the other teeth and to conserve more of the patient’s natural tooth structure. Mimicing the natural contours of posterior teeth is important because it allows for more natural function which in turn will prolong the life of the restoration.

Here is an example of a tooth shade and character that is difficult to match without the help of master ceramists. The ultimate result is a tooth that is indistinguishable from the adjacent teeth.

Here is a good side-by-side view comparing the older porcelainmetal crowns to the new all-porcelain crown. Again, we achieved an excellent color match to the adjacent teeth.

Here is another example of a tooth that would be difficult to match without the help of master-ceramists. Notice the idiosyncrasies in color, shape, and translucency that were matched beautifully.

Here is an example of a simple white (composite) filling that was leaking and decayed along the margin of the filling. By replacing the filling with a new composite and reproducing the natural contours of the tooth, we can create a tooth that will function properly when chewing, thus prolonging the life of the filling. Furthermore, use of a rubber dam (the blue plastic you see around the tooth) creates ideal conditions for placement of the filling, thus further prolonging the life of the filling.

Before: Failing composite filling with flat anatomy

After: Restored composite filling with natural anatomy placed under ideal conditions.

Here is an example of biomimetics by minimal intervention. For this small decayed area, a process called air-abrasion was use to remove the decayed tooth structure and preserve the outlying healthy mineral. The result is that the surrounding intact biological tooth-form is preserved and thus, the biological function of this tooth remains uncompromised.

Biomimetic Full Mouth Rehabilitation
Here is an example of a full mouth restoration that observes biomimetic (although not bioesthetic) principals. By opening up the patient’s bite and making room for all of the teeth to function, we were able to lengthen the patient’s teeth to normal size and return him to full functionality.
