KaVo SONICflex prep (prothetik): Tips for defined approximal finishing for adhesive inlays and onlays

Preparation of adhesive inlays and onlays

zeichnung-einfuehrung.jpg SONICflex prep

  • Precise preparation of various bevel angles, around margins
  • Prevention of undesired undercutting
  • Precise preparation result
  • Reproducible results
  • Improved preparation margins for dental technicians
  • No damage to adjacent teeth

 

The problem

Ideally, approximal adhesive inlays and onlays fit exactly into the cavity: with different bevel angles and edges, harmonious transitions, no undercuts. Practically this is extremely difficult to achieve. Rotating instruments often give rise to the opposite: irregular shapes and edges and hence a poor basis for the dental technician, unnecessarily large extensions.

The solution

KaVo SONICflex prep ceram permits perfect finishing and exactly defined cavities through precise transfer of the geometry of the tips directly to the tooth substance. With tips specially developed for adhesive inlays and onlays.

Design of tips: SONICflex prep ceram

For improved control during the achievement of the desired cavity geometries, a sonoabrasive preparation tip has been developed for the adhesive inlay cavity: the SONICflex prep ceram.

Its basic form is trapezoidal and the preparation surface is coated with a 46μm-diamond layer.

The occlusally divergent tip has a bevel angle of 75° cervically and a bevel angle of 60° laterally.

The lateral and cervical surfaces are mutually linked through a pronounced, rounded profile.

 

KaVo SONICflex prep - Features

 

 

prepceram_zusammen2.jpg SONICflex prep

  • No damage to adjacent teeth
  • Precise transmission of the tip's geometry to the marginal cavity angles
    - no undesired undercutting
    - specific achievement of the bevel angles
    - harmonious transitions between cervical and lateral edge areas
    - marginal areas and preparation surfaces are smooth and free from defects
  • Improve dental restoration by optimisation of cavity form
  • Suitable for all fully ceramic, or finegrain, hybrid composites (e.g. CEREC®*, EMPRESS®**, TARGIS VECTRIS®**, ...)
  • Reproducibility of treatment results
  • Reduction of treatment stress in critical processes
  • Reduction of the "skill-dependency" of complex preparatory work, due to ease of operation
  • Reduction of duration of preparatory work
  • Conservation of healthy tooth tissue

Inserting the SONICflex prep tips

The respective working end is screwed into the SONICflex handpiece using the torque wrench enclosed in the delivery, until it snaps in place audibly.

The tip is now securely attached to the handpiece

If the SONICflex handpiece is to remain on the treatment centre with tip attached, it is recommended to leave the torque wrench in place such that the working end poses no risk of injury.
