COMPLETE EDENTULOUS UPPER & LOWER ARCHES IMPLANT CASE

The scanning protocol for Complete Upper & Lower Arches Implant case, involves the following:

I. Patient Scan

  • Separate upper & lower Maxillary & Mandibular denture or duplicate denture with cotton rolls on each side of patient’s mouth.
  • Place a tongue blade with plane of occlusion perpendicular to floor under cotton rolls on one side of arch.
  • Scan the patient and export the DICOM file and save it under patient DICOM directory.

II. Impression Scan

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

III. Bite Registration Scan

  • Place PVS 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 with two dentures in place.
  • Scan bite registration and export DICOM data and save it in a separate folder under Bite PVS impression DICOM.


The steps to place the radiographic markers on the duplicate denture prior to scanning are:

  • Duplicate upper & lower dentures with clear acrylic.
  • Place at least (8) eight markers on each duplicated denture or on original.
  • Check teeth position, speech, function, esthetics, and phonetics of the dentures.
  • Place three radiographic markers on palatal or lingual areas at least 6-8mm below the CEJ of the teeth.
  • Put one marker on each side of buccal flange distal to Canine using gutta purcha material.
  • The holes should be at least 2 to 3mm in diameter and about 1.5 to 2mm deep.
  • Polish surface with a rubber wheel so that the surface of the gutta purcha is smooth.
  • The markers should not be placed in line – they should be tripoded.


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.
