Surgical Planning and Stent Fabrication Using Low Cost 3D Printing for Failed Mandibular Implant Replacement

Surgical Planning and Stent Fabrication Using Low Cost 3D Printing for Failed Mandibular Implant Replacement

The predictability and accuracy of virtual and guided implant surgery have been established in Oral and Maxillofacial Surgery literature. Traditionally, surgical guides are fabricated using industrial 3D printers at a remote laboratory site. A number of studies have been completed to assess the accuracy and cost of in-office 3D printing in surgical applications. Accuracy has been acceptable, however, more recent studies state that cost may be prohibitive. As the cost of 3D printers continues to decrease the availability of in-office 3D printing for clinical application will be more widely accepted. In this case, we will introduce a low cost method to fabricate a mandibular model and splint. 

This case demonstrates 3D modeling and 3D printing of a patient's mandible using data obtained from Cone Beam CT imaging. The slide series will show the preoperative virtual surgical planning and 3D modeling for implant placement. Intraoperative photography will illustrate the implant placement using a surgical stent fabricated from the 3D printed mandible. The total time spent and financial cost of planning and printing will be presented.
