WHITE PAPER ON 3D PRINTED SURGICAL GUIDES AND MEDICAL INSTRUMENTS
BRIEF INTRODUCTION Surgical guides are used to increase accuracy, safety and predictability while operating on a patient. The 3D Printed guides increase the accuracy and customization by allowing the procedure to be carried out only in the identified anatomical area, ensure safety by limiting the access to protect the neighboring blood vessels and tissues and increase predictability as the whole process would have been thought through while creating the guide. APPLICATIONS OF SURGICAL GUIDES Dental surgeries, especially for inserting implants are very intricate. The guides help in inserting implants to obtain maximum aesthetic result while limiting the depth of the drill as well as the implant. Spine surgeries where it is difficult to reach the required area without affecting the nervous system. Knee replacement surgeries as cutting guides. Hip replacement surgeries as cutting guides. Complex fractures involving difficult orientation of the bones in orthopaedic surgeries. ADVANTAGES OF 3D PRINTED SURGICAL GUIDES TRADITIONAL GUIDES 3D PRINTED GUIDES Don t facilitate easy access in cases where there is a difficulty in approaching the intended anatomical site. Accurate, fit perfectly to the anatomical site, as they are based on patient s MRI/ CT scan data
The surgeon is forced to reposition the guide multiple times to adjust to the orientation of problem area. Help to access the right location with precision, hence reducing time on the operation table The dental guides made using panoramic radiography are prone to expansion and distortion, setting error etc. leading to malposition of implants during placement. Help achieve right orientation, resulting in minimally invasive surgery thereby reducing recovery time. Less stability during surgery More stable as they are manufactured keeping in view the bone structure, available tissues around the site. 3D printed patient specific surgical guides make surgeries more predictable, minimally invasive, reduce the operating time and enable speedy recovery of the patient PROCESS TO MANUFACTURE PATIENT SPECIFIC 3D SURGICAL GUIDE The CT scan or MRI images of the affected part are studied. Accurate 3D virtual model of the required area is created from the Dicom images. The surgical process is planned by surgeon using 3D models and requirements for the guide are identified. 3D virtual models of the guides are designed.
The virtual models once finalized are 3D printed using additive manufacturing technique. HOW TO GET THESE SURGICAL GUIDES Send the patient specific images, instructions and the contact details to info@think3d.in or upload it at /dicom-3d-models We will go through them and have a telecon with doctor to confirm requirements and choice of material. 3D Views of the custom guide are shared along with measurements and fitment for feedback. 3D Printed surgical guide along with the specific bone (3d printed for mock surgery) is shipped to site CONTACT US Drop an email to info@think3d.in / callus @ 040-30191007.
