Stepped access, two step crown repair with amalgam internal core with HF etched, silanated, opaqued and resin veneer.
Shapes were ProFile S29 #5/.06 mesials, #6/.06 distals…large for that time but I was trying it out to see if it made any difference. Normal shapes at that time would probably have been a #3 or #4 mesials, #4 or #5 distals.*
10 year followup shown.
*S29 ProFiles where "Schilder inspired" safe-ended, landed rotary NiTi with a 29% increase in diameter. A #4 was around a 20/.06, and a #5 was around a 30/.06 and a #6 was around a 35/.06…so those were not that big of a shape.
