PROSTHESIS AND ESTHETICS
Acteon's Perfect Margin tips provide painless crown preparations. The surface of the teeth will be smoother than those obtained with a burr only, offering you a more precise impression, a stronger bonding and a higher durability of your prothesis.
PM1
PREPARATION ROUNDED EDGE

First instrument of the ultrasonic sequence, following the rotary phase. Intrasulcular dentin preparation and positioning of finishing line.
PM2
FINISHING ROUNDED EDGE
Diamond-coated 46μm
Correction of irregularities in the finish line and start of polishing. Its diamond coating, less dense than on the PM1, makes it possible to obtain a cutting edge finish.

Smooth
This entirely smooth instrument is last in the finishing sequence, improving the condition of the surface at the cervical limit before impression taking.
PM4

Conical, diamond-coated 46μm
After the rotating phase the PM4 tip is used to:
• Prepare the upper ⅓ of canal chamber.
• Shape anatomically the connection cone.
