The accurate placement of the implant is critical for achieving the results and as well as the exact alignment. SURGICAL GUIDE plays an important role in pre-surgical planning which then becomes simpler. The computed tomography (CT) imaging and CT-derived surgical templates are clinically significant improvements in accuracy, time efficiency, and reduction in surgical error, benefiting the patient, surgeon, restorative dentist, and the laboratory. Continued advances in software applications that enable enhanced planning give clinicians the vision necessary to deliver the desired results, while serving as an excellent communication tool between all members of the implant team. This article illustrates the advantages of using CT scan-based templates through various clinical presentations. Procedures were illustrated for single and multiple tooth applications in both mandible and maxillary arches.
A surgical guide is a medical device that is 3D printed based on the DICOM data which is patient specific. It is used for the accurate placement of the implant in the bone structure. It replicates the exact surfaces of the patient’s intraoral situation and assists the surgeon to perform the clinical application of drilling implants into the bone with optimal accuracy. The correct angulations are builted into the guide and the exact length is known from the top of sleeve to the ape of the implant.
In order to plan the treatment and design a surgical guide, the inputs collected are in two forms:
⇒ Ceramic data.
Ceramic data is 3D scanned data generated from doctor which is patients specific with the help of cone –beam computed tomography (CBCT).
Design in surgical guide make sure to select software that offers open STL file export to ensure strong and durable results.
The exact step-by step in treatment planning and surgical guide design varies by software, but generally follow:
