Fabrication of a craniofacial implant surgical and treatment planning guide

Bone and Skin-Supported Stereolithographic Surgical Guides for Cranio-Facial Implant Placement

“…This location corresponds roughly with the antihelix and thus provides sufficient space for the abutments of the auricular prosthesis. On the other hand, virtual planning of the implant locations was described in some reports [26,28,29,36,37].…”

“…Preoperative planning of the craniofacial implants was reported as important to eliminate the subsequent improper placement of the implants [36][37][38]. Maintaining of the CT based 3D virtual model of the craniofacial structures as well as the defect area has been reported as the preliminary requirements for the surgeon to select an appropriate site for patients whose anatomy does not allow placement of implants conventionally [32][33][34][35].…”

“…The surgical guide obtained with the help of this virtual model may be used in surgical interventions [26,29,[36][37][38] so that the surgeon can visualize the correct placement of implants directly on the bone [36]. For this reason, surgical guides were known to provide the prevention from the unexpected surgical complications related to the anatomical specifications [1,26,37,38].…”

“…For this purpose, implant site may be scanned radiographically or optically [30][31][32] and modeled digitally [33][34][35]. Surgical guides produced with stereolithographic (STL) techniques in order to the computerized tomography (CT)-based planning, may be employed in surgical intervention [36][37][38].…”

A Modified Technique for Orientation of an Adhesive Retained Ear Prosthesis: Case Report

“…The boxing wax was discarded and the excess flash was trimmed after the resin had polymerized (Figure 3). 1 A groove was made in the acrylic resin ear's antihelix region and a 1.2 mm messing wire was embedded in resin.…”
