Complete Data on Twin Luscent Anchors with Clinical - Dentatus ...

  1. 1. Benefits Procedure Case Study Kits Literature The Twin Luscent winning combination: Twin Luscent Anchors Light Transmitting Esthetic Posts for Endodontically Treated Teeth • light transmission • esthetic • twice the retention
  2. 2. Primary Benefits Superior functional and esthetic restoration Patient Time-saving procedure, superior end product Clinician
  3. 3. Primary Benefits Strengthens the restoration Strong Compatible with brand name dual-cure adhesives/resins Convenient Single visit procedure: simultaneously luting the anchor and building a monoblock core Fast Removable Easily removed using Dentatus reamers
  4. 4. Esthetic <ul><li>Twin Luscent Anchors eliminate shadows at the gingival, root and crown interface as well as through thin composite restoration </li></ul><ul><li>Twin Luscent Anchors reflect the surrounding colors and hues compatible with natural esthetics </li></ul>
  5. 5. Light Transmitting <ul><li>Twin Luscent Anchors effectively polymerize composite within the deep confines of canals </li></ul>Including: • Large canals weakened after endondontic treatment • Extension of caries into the coronal portion and pulp chamber • Developmental anomalies • Trauma or over-preparation of root canal
  6. 6. <ul><li>Light or dual-cure composites bond to the fiberglass-reinforced anchors and the canal wall creating a cohesive and very strong foundation </li></ul>Monoblock Strength
  7. 7. Clinicians Report: Reduced Incidence of Root Fractures <ul><li>Twin Luscent Anchors absorb and dissipate sudden stresses </li></ul>Potential fracture location with fiberglass-reinforced composite posts Vector of Force Vector of Force Fractured Post and Crown Fractured Post and Crown Potential fracture location with metal posts Vector of Force Fractured root Vector of Force Fractured root
  8. 8. Removable <ul><li>Anchors are easily removed with either a large size NiTi rotary engine file or Dentatus Reamer </li></ul>Example Post fracture-post removal • Cut post flush to tooth • Create pilot hole with small round bur • Remove post with Gates Glidden #4 or Probos Pathfinder • Continue to remove post with largest nickel titanium rotary file
  9. 9. Example (continued) • Probos Pathfinder or Gates Glidden down the center of the post • Large Nickel Titanium file in rotary handpiece to remove remaining post • Cement post or cast post and core • Restore with at least 1.5-2.0 mm ferrule Removable
  10. 10. Anchor Design Twin Luscent Anchor Eliminates hydro-static pressure Easy release of excess resin Longitudinal vent-grove Creates an anti-rotational resistance in the surrounding polymerized resin Anti-rotational resistance Parallel and can be alternatively placed into wider canals Cone-shaped end can be placed in deeper/narrower canals without excess removal of dentin or canal wall Double end alternatives Cone-shaped end/ parallel end Provides double retention against accidental debonding of resins and other restorative materials Mechanical resistance Narrow radial midsection Benefit Element Original Luscent Anchor Optimal choice for very narrow and small canals, from 0.8 mm to 1.2mm True taper
  11. 11. Shape Matches Root Form <ul><li>Twin Luscent and Luscent Anchors completely fit within the confines of natural teeth </li></ul><ul><li>Anchor design is tapered apically to match root form, minimizing unnecessary removal of dentin in the canal </li></ul>Twin Luscent Luscent apical seal CEJ
