Overview: This article provides instructions for identifying and resolving common causes for improperly seated implant scan bodies to ensure accurate digital impressions.
Identifying Incorrect Components
Review the surgical report to verify the implant manufacturer, system, and platform diameter. Because the support team does not provide implant identification services, consult resources like preat.com for additional guidance if the system is unknown.
Every scan body features a reference number printed on the side. The software validates this reference number during the restorative case setup. Contact support if assistance is required regarding these component details.
Resolving Anatomical Interference
Anatomical structures can prevent a scan body from seating correctly. Verify that dental floss passes through the contact areas of teeth adjacent to the implant.
Addressing Bone Impingement
Bone impingement is typically visible on a radiograph. This issue often presents as a visible gap between the implant fixture and the scan body.
Addressing Tissue Impingement
Tissue impingement often causes gingival blanching or physical resistance during placement. To resolve this, remove the interfering tissue or place a healing cap to achieve a uniform emergence profile before scanning.
Correcting Scan Body Angulation
The scan body screw must drive into the implant fixture passively. If the scan body meets resistance or fails to seat, the angulation may be incorrect. To correct the angulation:
Unscrew the scan body from the implant.
Adjust the insertion angle.
Replace the scan body into the implant fixture and ensure it seats correctly without force.
