The video above illustrates how to repair a fractured anterior (front) tooth with a dental filling material. Initially, the dentist needs to be able to remove any unsupported enamel & incorporate a bevel which will help camouflage the dental filling material. This incorporates minimal preparation & will allow for a better bonding mechanism. After, a teflon tape is placed on the adjacent tooth to prevent any of our etching/bonding solution from attaching to the adjacent tooth. After washing & drying the etchant, the dentist will brush a bonding material over the prepared site & light cure. If a wax-up was made prior to the procedure, we are able to make a stent that can help build the lingual wall of the tooth. This helps the dentist achieve a predictable means of designing a filling that harmonizes with the adjacent teeth. Composite is then added & cured in incremental steps to avoid resin shrinkage. Final polishing can be achieved with a series of polishing discs.
I hope this video helps patients visualize the procedure & gives dentists some tips on how to achieve a more predictable filling. The dental filling was done on a typodont (fake teeth); therefore, the composite filling stands out. In a patient case, we would utilize various composite to blend the filling with the natural teeth.
