Model-less implant prosthetic work with intraoral scanning of encoded healing abutments

Patient information / Treatment plan Patient information: 61 years old / male Treatment plan: Neo IS3 Active implants, Titanium custom abutments, and splinted monolithic zirconia crowns

Preoperative observation

Encoded healings in place for scanning 3 implants in Max. right quadrant

1st scan of maxilla focusing on the soft tissue around implants

2nd scan is focused on encoded healing abutments to obtain information of the implant position.

Intramural scan data of encoded healings

Library data of encoded healings

Merging process between intraorally scanned encoded healing and library data

You can ensure the scan quality of the encoded healings by designating the area to obtain STL file.

The CAD design of the abutments can be viewed thru the full wax-up and modified to allow space for final restoration.

CAD designs of custom abutments are completed.

The detailed view of the CAD design and fabricated custom abutment

The scan data of milled abutment are merged onto the original CAD design for verification.

This process often shows a discrepancy between the scan data and the CAD design of abutment.

Outline of the milled abutment is in gray and the CAD design in blue. In most cases, those two lines do not coincide completely.

Final custom abutments and monolithic zirconia crowns

The custom abutments are seated and tightened to recommended torque.
