5. Primary Benefits Fast • One-stop procedure: simultaneously luting the anchor and building a monoblock core Convenient • Compatible with brand name dual-cure adhesives/resins Removable • Easily removed using Dentatus reamers

6. Esthetic • Twin Luscent Anchors eliminate shadows at the gingival, root and crown interface as well as through thin composite restoration • Twin Luscent Anchors reflect the surrounding colors and hues compatible with natural esthetics

7. LightTransmitting • Twin Luscent Anchors effectively polymerize composite within the deep confines of canals

8. Light Transmitting Including: • Large canals weakened after endondontictreatment • Extension of caries into the coronal portion and pulp chamber • Developmental anomalies • Trauma or over-preparation of root canal

9. MonoblockStrength • Light or dual-cure composites bond to the fiberglass-reinforced anchors and the canal wall creating a cohesive and very strong foundation

10. Reduced Incidence of Root Fractures • Twin Luscent Anchors absorb and dissipate sudden stresses Potential fracture location with fiberglass-reinforced composite posts FracturedPost and Crown FracturedPost and Crown Vector of Force Vector of Force Potential fracture location with metal posts Fracturedroot Fracturedroot Vector of Force Vector of Force

11. Removable • Anchors are easily removed with either a large size NiTi rotary engine file or Dentatus Reamer

12. Removable – Example 1/2 • Post fracture-post removal • Cut post flush to tooth • Create pilot in post with pin drill • Remove post with GatesGlidden #4 or Probos Pathfinder • Continue to remove post with largest nickel titanium rotary file

13. Removable – Example 2/2 • ProbosPathfinder or Gates Glidden down the center of the post • Large Nickel Titanium file in rotary handpieceto remove remaining post • After removal of post, resize canal with another post • Cement post or cast post and core • Restore with at least 1.5-2.0 mm ferrule

14. Original Luscent Anchor True taper Optimal choice for very narrow and small canals, from 0.8 mm to 1.2mm Anchor Design- Twin LuscentAnchor

15. Shape Matches Root Form • Twin Luscent and Luscent Anchors completely fit within the confines of natural teeth • Anchor design is tapered apically to match root form, minimizing unnecessary removal of dentin in the canal apicalseal CEJ Twin Luscent Luscent

19. Benefits of the Physical Properties (4/4) In Vitro Post-Tooth Retention • All posts inserted to same length (9mm) • All posts cemented with resin cement (Bisco) except “ParaPost (ZOP” that were cemented with zinc phosphate cement (as a control) • All ParaPosts are titanium Source: Al-Harbi FA, Nathanson D.

27. Case Study Restoring the EndodonticallyTreated Tooth with Fiber Reinforced Resin Posts Howard E. Strassler, DMD, FADM, FAGD Department of Restorative Dentistry Dental School University of Maryland

28. Indications for fiber posts • Need for esthetic translucency • Need for root reinforcement, sealing and strengthening • At least 1.5 mm ferrule in the tooth preparation • Provide for a monoblock system of core bonded to post bonded to tooth • Create a failsafe design that if traumatized the tooth crown and post would fracture leaving the root intact

29. Important points for post selection • Posts must transmit light to eliminate gingival and tooth shadowing • Post should be tapered following the true shape of the root canal and leaving more radicular dentin • Post should not transmit forces down the root during trauma; the post should dissipate forces and fracture before the tooth and root • If broken, the post be easily removed • Post comes in multiple sizes to accommodatedifferent root canal diameters

30. Preoperative View • Endodonticallytreated maxillary lateral incisor with defective Class 3 restorations and an endodontic access opening Twin Luscent Anchor • Decision to restore with adhesive composite resin supported by a bondable Twin Luscent Anchor

31. Post Space • The length of the canal was determined with a radiograph • Sized reamers determined the Twin Luscent size to be used • Post space (length) was created by removing the guttapercha with a Pathfinder then a Luscent Reamer

32. Anchor Placement • Twin Luscent Anchor was tried into the canal and length verified • Canal was etched for 15 seconds

33. Rinsing and drying the canal • Canal was rinsed using an endodontic irrigation syringe with water • Canal was dried with a large paper point

34. Adhesive application • A 4th-generation adhesive was used with a separate primer and adhesive resin in the root canal • The adhesive must be either a dual cure or self-cure adhesive compatible with a self-cure or dual-cure composite resin cement

35. Cementation of Twin Luscent • Twin Luscent Anchor painted with adhesive • Dual-cure composite resin cement syringe into the canal with a Needle Tube

36. Anchor Placement • Twin Luscent Anchor seated into the root canal and cemented. Note, twirling motion used in seating the anchor. • Light cure for 60 seconds

37. Preparation for all-ceramic crown • The Twin Luscent Anchor was cut down to the level of the access with a diamond on a high speed handpiece • Restoration of the access and Class 3s with composite resin. Note, no discoloration of gingiva with Twin Luscent Anchor. • Preparation for an all-ceramic crown

38. All ceramic crown cementation • Preparation etched for 15 seconds, rinsed and dried • Dentin primer painted on preparation

39. All ceramic crown cementation • Dual cure adhesive painted on preparation • All-ceramic crown cemented with dual-cure composite resin cement

40. Final all-ceramic crown • Excess cement removed; crown light cured for 30 seconds on facial surface, 30 seconds on lingual surface • The final restoration, highly esthetic and translucent
