@mundodontoo: The central Y isn't decoration. It's the architecture. Every time you load direct composite without sketching the Y first, you're drawing *a line* where there should be *a map*. 3 strokes that change everything: ↳ Mesial triangular fossa ↳ Distal triangular fossa ↳ Central Y that fuses them Sketch first. Layer next. Polish last. 📍 Save this for your next Class I. — Stunning anatomy reference by @viktoriaa_apoikova — animated by mundodonto frame by frame to show the build sequence. — #odontology #dentistry #composite #operativedentistry #toothanatomy
