An image-guided system based on custom templates: case reports.
BACKGROUND: With the use of computer-assisted surgery and other modern imaging technologies, the surgeon's procedures have been modified. PURPOSE: The purpose of these case reports is to show the clinical predictability of dental implant placement using an image-guided system. MATERIAL AND METHODS: An acrylic template is made on the patient model. After computed tomographic examination, a treatment plan is established with appropriate software. To fabricate the surgical template, it is necessary to use a dedicated drilling machine. The first osteotomy is achieved through the template with a 2 mm twist drill. The template is then removed, and the osteotomy is completed, followed by implant placement with standard clinical procedures. RESULTS: An excellent predictability was observed between the planned implants and those placed in the two maxillary cases presented: a full upper screw-retained bridge and two single units. CONCLUSIONS: This new technology improves the treatment outcome and optimizes the surgical procedure.
