Bicon dental implants have been in use worldwide for over 25 years but are relatively new in Australia. These are truly amazing implants that will defy current accepted systems.
What’s good about it
The most obvious thing is the small size. For example, a 5mm x 5mm implant will support a posterior crown.
In the mandible where the IDN bundle may be close, using a 5mm implant will be sufficient as opposed to a standard 10mm. Similar advantages exist in the maxilla when the ridge is not very deep.
Width sizes range from 3mm up to 6mm and offer a great variety of lengths up to a maximum of 8mm.
With optimal drilling speeds of 50 rpm, all autogenous bone can be saved and replaced. Placement can be performed freehand or with a fully guided kit, using just one drill for the osteotomy. Various abutments are available for different tooth profiles with different emergence profiles, including locators. The Morse taper connection absolves use of the screw and allows a hermetic seal with wonderful soft tissue tolerance.
Generally, three appointments are required for placement, impression and crown/abutment insertion, with analog CAD/CAM ability from the second stage.
Osseointegration is faster as there’s no pressure placed on the contiguous bone.
What’s not so good
Implant stability is not an immediate facility unless there are more than two abutting implants or splinting to an adjacent tooth. The surgical site is generally closed after surgery and two to three months are required before the second stage. There is no direct intra-oral CAD/CAM restorative technique available.
