18 I I case report _ ceramic bridge _In the following case, the CEREC 3D system and its one appointment capabilities played an es- sential part in the treatment. The patient suffered from facial myalgia and could not handle a repeat visit for a second try in/insert, owing to the poten- tial stress it would cause. She had previously expe- rienced involuntary facial episodes—the drill had been bitten on—causing more trauma. Thepatienthadbrokentooth#31atthegumline. The rest of the tooth had been removed some time ago, leaving a gap. All treatment options were ex- plained to her. We offered her a same-day ceramic bridge and informed her that this would be entirely experimental, even though I have made many of these types of full contour bridges. Dr Carl Boyko, Welcome Smile Dental (Calgary, Canada), and I created the bridge. Firstly, Dr Boyko measured the span of the area that needed to be bridged.Oncemeasured,wediscoveredthatthearea could support an I-14 TriLuxe Forte (VITA), which would be used to manufacture the bridge. Dr Boyko then prepared the tooth #41 and 32 abutments. Following, he created a temporary bridge that would be used by the CEREC system as a temporaryreference.Simultaneously,wemeasured the shade of the surrounding teeth (Fig. 1).

This creates a reflective surface that allows the CEREC 3D Bluecam to capture the optical im- pressions of the preoperative (occlusion) images.
