PARTIALLY EDENTULOUS IMPLANT CASE

The scanning protocol for Partially Edentulous Implant case, whether Anterior or Posterior, involves the following:

I. Patient Scan

  • Separate the upper and lower arches of the patient with two cotton rolls.
  • Place a tongue blade with the plane of occlusion perpendicular to the floor under the cotton rolls on one side of the arch.
  • Scan the patient and export the DICOM file and save it under patient DICOM directory.

II. Impression Scan

  • Put upper PVS impression on chin holder in the same direction that the impression was placed in the patient's mouth.
  • Scan impression and export DICOM data and save it in a separate folder under Maxillary PVS impression DICOM.
  • Put lower PVS impression on chin holder in the same direction that the impression was placed in the patient's mouth.
  • Scan impression and export DICOM data and save it in a separate folder under Mandibular PVS impression DICOM.

III. Bite Registration Scan

  • Put bite registration on chin holder. This bite should’ve been taken in the patient's mouth in centric occlusion just like a conventional crown and bridge bite.
  • Scan bite registration, export DICOM data, and save it in a separate folder under Bite PVS impression DICOM.

The steps to take the bite registration of the patient in centric occlusion are:

  • Roll PVS putty into a 'hot dog' like roll ensuring that the PVS putty is thicker in the distal extension area.
  • Place it over patient's occlusal area around the arch and position thicker portion in the distal extension.
  • Ask patient to bite down ensuring that the bite is accurate and that the midline matches.
  • Mold putty around teeth and ensure distal extension bite captures tissue on one side and teeth on the other.

Note: Please make sure that you place a ONE INCH FOAM on the Chin holder before scanning in order to separate the bite registration, the Impressions, and the dentures. The foam will act as a separating agent to avoid fusion of the scanned objects with the chin holder.
