The Scan & No-Scan-Appliance Technique
Scan Appliance Technique
1. Restorative Doctor:
Provide master casts or master cast quality, full-arch maxillary and mandibular silicone impressions, bite registration, study model and full-face natural smile photograph (do not use lip retraction) capturing the patients’ head from just above the hair to just below the chin. Identify treatment objectives, provide desired case plan and list potential implant sites.
2. ROE Dental Laboratory:
Create a diagnostic work-up of the proposed final tooth position. Once approved by the general dentist, a CT scan appliance is fabricated - following the wax-up, or duplicating a patients’ existing denture. If using the patient’s denture, hard-reline if necessary for fit before making the scan appliance. Provide the name of the planning software you want to use on the case. iDent, Nobel Guide, Simplant BlueSkyPlan. The scan appliance construction protocol for each software system is different.
3. Restorative Doctor:
Try-in the scan appliance to verify the fit of the scan appliance. If the fit is not ideal adjust accordingly or capture new impression and remake the guide. If the fit is perfect refer the patient with the appliance to the imaging center for the CT scan.
4. Imaging Center:
Record CT scan – specific protocol must be followed for each planning software (contact ROE). After completing your first scan call ROE while patient is still in the chair to confirm the scan accuracy and to verify that the data is being saved and sent in the correct format! Upload the DICOM file to ROE using www.dentalimplantplanning.com. The imaging center can download the specific protocol via the above web site or contact ROE.
5. ROE Dental Laboratory:
Preplan case using planning software ensuring implant locations meets esthetic and functional requirements, and fit within the confines of the existing bone structure as predetermined by the diagnostic wax-up and CT scan.
6. Restorative dentist, surgeon and laboratory:
Attend a live interactive online meeting to modify and approve the surgical plan for guide fabrication. Specialist completes and returns the drill sequence and case-approval Surgical Guide Order Form to ROE.
7. ROE Dental Laboratory:
Create the surgical guide for iDent, BlueSkyPlan, SimPlant, or NobleGuide and returns it to the specialist for surgery.
