38. Occlusal view of eight shouldered abutments ninety days after their placement and prior to their being removed for the making of an implant level transfer impression.


39. Facial view of shouldered abutments with the right side prosthesis replaced to facilitate the recording of an occlusal registration.


40. Occlusal view with five abutments removed from their implant wells.


41. A white impression post is being inserted into 3.0mm implant well for the recording of an occlusal registration.


42. A second impression post is being inserted into the left central implant well.


43. A third white impression is being inserted.


44. A black impression post is being inserted into the 2.0mm implant well of the left canine.


45. White impression post is receiving the mandatory axial tap to assure definitive seating in the well of the implant.


46. Occlusal clearance of the five impression posts is being confirmed prior to the addition of red acrylic for the occlusal registration.


47. Red acrylic resin being injected around left impression posts while patient is occluding on right transitional crowns.


48. Additional red acrylic being injected around impression posts.


49. Patient is occluding on right transitional crowns while the red acrylic is polymerizing.


50. After removal of the transitional prosthesis an impression post is being tapped into the implant well to record the right side occlusal registration.


51. Acrylic resin being injected on right side while patient occludes on left side.


52. Patient occludes while right side acrylic is polymerizing.


53. Right side registration is being removed.


54. Left side registration is being removed.


55. A new set of impression posts are being inserted into the well of the implants for the making of an implant level transfer impression.


56. Impression material is being injected around impression posts.


57. Transitional prosthesis is being used to facilitate the re-seating of the shouldered abutments into the implant wells.


58. Shouldered abutments seated with only finger pressure in their implant wells.


59. Transitional prosthesis seated in three pieces.


60. Intra-oral bonding of the transitional prosthesis.

74. A second integrated Abutment Crown™ is being inserted.


75. Initial stabilization of the Integrated Abutment Crowns™ is achieved by tapping on the orientation jig.


76. Definitve seating is achieved by using a modified white temporary healing abutment in a straight driver to direct the seating force onto the labial surface of the crown which is in line with the long axis of the shaft of the abutment.

83. Initial seating is being achieved by tapping on the orientation jig.


84. Dental floss is being used to confirm the appropriate interproximal contact. It is essential to have minimal contact that does not preclude the seating of the abutment shaft in the well of the implant.


85. Definitive seating is achieved with the use of a white temporary healing abutment inserted into a straight driver.
