Griptab Crown Clinical Case Study by Dr Graeme Milicich


Published on

Griptab is a must for dentists, dental assistants and lab technicians - anyone handling crowns, inlays, onlays and veneers.

Think of the value of a handle to a cup. Triodent has applied that same principle to indirect restorations. By adhering Griptab to the restoration, you have a reliable grip and total mastery of the placement process, especially when using Triodent Pin-Tweezers for extra maneuverability, although small hemostats will do.

Griptab Crown Clinical Case Study by Dr Graeme Milicich

  1. 1. Griptab Crown Case<br />By Dr Graeme Milicich, BDS<br />
  2. 2. 1<br />A 21-year-old female patient presented with a central incisor that had previously had an incisal 1/3 fracture restored with a bonded composite (Fig 1). She had suffered another blow to the tooth and the restoration and all the palatal enamel had been lost. The palatal fracture was sub-gingival and down to the bone in one area.<br />
  3. 3. 2<br />The tooth was prepared for an E4D CAD/CAM crown and the sub-gingival margin was exposed (Fig 2) using a Waterlase MD. The bone in the region of the fracture was lowered (Fig 3 & 4) to re-establish biological width using a closed flap approach. <br />
  4. 4. 3<br />
  5. 5. 4<br />
  6. 6. 5<br />An impression was taken and the patient released with a temporary crown. A model was poured and scanned into the E4D design center and a crown was designed and milled using an A1 IPS Empress multi-block <br />
  7. 7. 6<br />
  8. 8. 7<br />The milled restoration was then contoured to create the surface micro anatomy, stained and glazed.<br />
  9. 9. 8<br />Prior to trying in the crown, a Griptab was bonded to the incisal region of the labial surface. This was then used to control the crown while a correct shade of Variolink Veneer bonding resin was chosen using the try-in pastes. The position of the Griptab did not interfere with the selection of the correct shade of bonding resin cement.<br />
  10. 10. 9<br />Once the correct shade had been selected, the Griptab was re-engaged with pin-tweezers and the crown removed from the tooth. The try-in paste was rinsed out prior to HF etching and silanation.<br />
  11. 11. 10<br />Immediately post-cementation, the adjacent teeth were slightly desiccated, which highlighted the white spots in the enamel.<br />
  12. 12. 11<br />A couple of minutes of rehydration began to reduce the intensity of the enamel white spots on the adjacent teeth <br />
