Sorry for the blood and gore. Patient fractured #8, #7 is mobile but I would suspect that it should firm up after the inflammation goes down.
Scanned the patient in both CEREC and Galileos. Its important when designing in CEREC to look at the CEJ of the proposal relative to the platform of the planned implant. You want to be 2-4mm apical.
The problem i see in immediates is the tendency to be too apical. Its hard to judge where to put the platform relative to the coronal aspect of the socket. If you are too low you will get a proposal in CEREC for the drill body that is inverted.
In my classes one concept that students have a hard time with is “What does CEREC mill out?”. This illustrates it pretty well, the Reference body makes an indentation in the Thermoplastic Tray Material and CEREC mills out the Drill Body that fills its place.
I needed about 2mm more than the head of my handpiece would allow, so I used the Drill Extender to get a thick enough D2 value.
Always look at your pilot. We want to be centered in the socket and slightly palatal.
Final, due to the curve of the arch I look too close to the lateral, but I am not. You can see in the axial how the socket would superimpose. I went with a 3.7mm implant vs a 4.2 to avoid the large Incisive Canal.
Final CEREC Temporary Crown. You can see the inflammation going down. Stock Zirc abutment.
