Bicon Integrated Abutment Crowns™: Two Stage Less than Ideal Placement of Three Mandibular Implants and their Restoration with Integrated Abutment Crowns™
This case demonstrates the surgical exposure of the mental foramen prior to the two stage less than ideal shallow placement of three mandibular implants. Their restoration with three Integrated Abutment Crowns™ reveals the superior gingival aesthetics that can be achieved even with implants that are less than ideally placed.

38. Healing plug is being removed from the well of the 4.5mm x 8.0mm HA coated implant.


39. Green 3.0mm plastic impression post being inserted into the 3.0mm well of an integrated implant for the making of an implant level transfer impression.


40. Impression post being tapped into place to assure its proper seating.


41. Impression material being injected around the impression posts for the making of a full arch implant level transfer impression.

51. White healing abutment being removed.


52. View of implant wells and soft tissue sulci.


53. Integrated Abutment Crown™ being inserted to initially evaluate its appropriateness.


54. Floss being used to confirm the fact that the inter-proximal contacts are passive and will not interfere with the engagement of the locking taper.


55. Integrated Abutment Crown™ is being slightly rotated with an extraction forceps and gauze to adjust its mesial interproximal contact.


56. Definitive seating of the restoration and engagement of its locking taper connection is being achieved by occlusal pressure on a cotton applicator.


57. Integrated Abutment Crown™ being inserted to initially evaluate its appropriateness.


58. Floss being used to confirm the fact that the interproximal contacts are passive and will not interfere with the engagement of the locking taper.


59. Adjustment of interproximal contact since a too tight interproximal contact will prevent the engagement of the locking taper and possibly result in subsequent loosening of the Integrated Abutment Crown™.


60. Definitive seating of the restoration and engagement of its locking taper connection are being achieved by occlusal pressure on a cotton applicator.


61. White healing abutment in a straight handle is being used to tap the Integrated Abutment Crown™ into the well of the implant.
