The treatment plan included …<br />

restoration with all-zirconia<br />

custom abutments and a 4-unit<br />

all-ceramic fixed prosthesis to<br />

restore the anterior incisors<br />

to form and function.<br />

Figure 19: Abutment design (occlusal view)<br />

Using the iTero scanner with updated software (version 4.0),<br />

a full maxillary arch scan, full mandibular arch scan and<br />

centric bite in maximum intercuspation were completed.<br />

A three-dimensional digital record of the patient’s anatomy<br />

was created from these scans (Fig. 15) and electronically<br />

submitted to <strong>Glidewell</strong> Laboratories to be used in the CAD/<br />

CAM restoration process.<br />

At <strong>Glidewell</strong> Laboratories, the virtual scan was registered to<br />

the scanning abutments (Figs. 16–17). This provides the dental<br />

technicians with the implant system, size, axis, position relative<br />

to the adjacent anatomy and locking feature orientation.<br />

A virtual zirconia abutment was designed using 3Shape’s<br />

<strong>Dental</strong>Designer software (3Shape Inc.; New Providence,<br />

N.J.) and the <strong>Glidewell</strong> Digital Abutment Library (Figs. 18–21).<br />
