No lines this time — just the cavity, and you.

Once you know where each layer goes, this is where you make the call yourself. Same realistic anatomy, no guide — you're building the muscle memory, not following a map.

• Realistic lower molar & premolar anatomy
• Cavity only — no internal guide lines
• Practice placing each layer by feel, not by tracing
• Improve carving, contouring & hand control
• Built for repeated practice
