“ prosthetically guided implantology where ideal placement of implant is determined by the definitive restoration, use of radiographic and surgical STENT in conjunction with dental CT scan can play an important role. A stent is an appliance used for radiographic evaluation during treatment planning for implant placement and during surgical procedures to locate optimal implant placement site.”
“The STENT with dental CT scan enables the dental team to identify specific sites of prospective implant surgery and hence determines the optimal position and angulation of implant relative to occlusal load. Aided by stent the surgeon can avoid undesirable implant site preparation and minimize unnecessary osteotomy, resulting in favorable design of prosthesis, reduced surgical trauma, reduced surgical time and increased patient comfort.

“With an auto polymerizing acrylic resin (Rapid Repair, Pyrex polymer, India), STENT was fabricated as a flat plane over the trimmed teeth and implant position was transferred on it.”
