Time saving system
David Reaney explores an implant impression system made to be simple.
The Encode Complete Impression System enables the restorative dentist to transfer information from the patient regarding the type and position of Biomet 3i implants, adjacent dentition and soft-tissue to the dental technician who provides a patient-specific final abutment for cement-retained restorations utilising CAD/CAM technology. Screw-retained single unit crowns in porcelain fused to zirconia can also be provided using this technique.
The procedure involves a direct impression of the uniquely-coded Encode Complete healing abutment in-situ and eliminates the need to remove the healing abutment and the use of a pick-up post to provide a fixture level impression, potentially preserving supporting bone and papilla.
Abutment
The markings machined into the exposed occlusal surface of the Encode Healing abutment provide the following information:
The above information is all that is required to allow the design and fabrication of the definitive Encode abutment utilising a scanner that interprets the codes from the Encode abutment. A robotic system is used to place the implant analogue into the working cast and CAD/CAM technology used to design and mill the definitive Encode abutment from titanium or Zirconia.
