37. View of Integrated Abutment Crown™.
Third Clinical Visit:    


38. Transitional prosthesis being removed for the insertion of Integrated Abutment Crown™.


39. Integrated Abutment crown™ being inserted initially to evaluate its appropriateness.


40. Crestal relieving incision being made to facilitate the seating of the Integrated Abutment Crown™.


41. Well of implant being cleaned with alcohol on a cotton tipped applicator.


42. Integrated Abutment Crown™ being reinserted.


43. Yellow thermoplastic custom seating jig, which was formed with a crown alignment device, in a crown seating tip attached to a straight handle facilitates directing the tapping forces in the long axis of the abutment post and implant well.


44. Post insertion radiograph.


45. Height of buccal gingiva being marked to facilitate the adjustment of the cervical aspect of the Integrated Abutment Crown™.


46. Buccal aspect of Integrated Abutment Crown™ being reduced with #7404 bur.

48. Integrated Abutment Crown™ being inserted.


49. Incisal contact being adjusted with pink silicone polishing wheel.


50. Mesial composite veneer on stone model fabricated to close the diastema between the two central incisors.


51. Etchant being applied in preparation of the bonding of the veneer.


52. Bonding agent being applied.


53. Bonding agent being light cured.


54. Surface of the veneer being roughened for bonding.

62. Articulating paper being used to confirm interproximal contacts.


63. Blue marking indicates excessive interproximal contacts which must be adjusted to assure passive contact for the engagement of the locking taper connection.


64. Interproximal contact being adjusted.


65. Integrated Abutment Crown™ being reinserted.


66. Diamond finishing strip being used to lighten the interproximal contact area eliminating the possibility that the contact may prevent the engagement of the locking taper connection.
