Acteon® Ultrasonic Perfect Margin® Tips

Acteon NEWTRON Perfect Margin® tips are ultrasonic prosthetic finishing tips used for coronal or coronal-radicular prosthetic preparations finishing. Features and benefits include:

Atraumatic preparation without bleeding:

• High precision movements thanks to tactile sensation.
• Laser marking at 1 mm to view and control the sulcus penetration in order to preserve the epithelial attachment.

Perfect integration and longevity of the crown:

• Dentinal tissue can be quickly and safely prepared in areas where it would be delicate to use a diamond bur.
• Clear and smooth finishing lines.
• Improved quality of impression-taking and extremely precise cervical adjustment of the prosthetic restoration.

Two kits for two different approaches:

• PerfectMargin Rounded: quarter-round shape tips, whose form is in harmony with burs used in supra-gingival.
• PerfectMargin Shoulder: shoulder shape with rounded internal angle tips, to prevent cervical margin lip during intrasulcular finishing.

Indications for Use

• PM1. Preparation, rounded edge, diamond-coated tip 76 μm. First instrument of the ultrasonic sequence, following the rotary phase. Intrasulcular dentin preparation and positioning of finishing line.
• PM2. Finishing, rounded edge, diamond-coated tip 46 μm. 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.
• PM3. Polishing, rounded edge, 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. Corono-radicular preparation, conical, diamond-coated 46 μm. After the rotating phase the PM4 tip is used to: prepare the upper ⅓ of canal chamber; shape anatomically the connection cone; clean the root walls; smooth the entry cones for the anatomical posts.
• PMS1. Preparation, shoulder shape, diamond-coated tip 76 μm. First instrument of the ultrasonic sequence, after the rotary phase. Penetration of the sulcus to continue preparation the dentine, in order to correct the "lip" of the preparation and obtain a shoulder-shape finishing line.
• PMS2. Finishing, shoulder shape, diamond-coated tip 46 μm. Shoulder shape finishing line without risk of a lesion in the attachment system, and beginning of polishing thanks to its lower grit diamond-coating. When the yellow setting of the ultrasonic generator is used, PM2 and PMS2 can be used for polishing the dentine.
