Subleties can make all the difference. The 21 featured an old MBL restoration and a loose contact verging on diastema and exaggerated incisal embrasure. We adopted the pre-crimped Mylar matrix technique employed in Skulpting Skool 102 and freehanded the linguoproximal aspects of 21 and used the pull-through technique to make the contact area more uniform and simultaneously correct the midline cant. A simple bilaminar technique was used using Kerr Harmonize Enamel A1 and Dentin A2 as pre-selected before dehydration.
Beautiful material to skulpt and polish!
