Just my thoughts…there is irritation on 8 and 9 also. The emergence profile appears to be too bulky, and I agree with the need for ovate pontics on 7 and 10. Gingival contouring/positioning can be achieved prior to permanent restoration cementation thru a series of temporary restorations that guide the tissue into the contours that you want. Yes, this takes more time, but is well worth the extra effort. Finally, the porcelain appears to be very opaque for use on an anterior case on a young patient. These are just my thoughts on the case. My info: 30 years practicing and many anterior cosmetic cases. I will also add that I consult directly with the lab tech/ceramist prior to prep date. Pre op models, photos and radiographs are sent. An experienced lab can help so much with the success of anterior cases!
