Pre-prosthetic surgery planning using model printed from computed tomography prototyping: Torus palatinus

Abstract

Palatal torus can interfere with rehabilitation with dental prosthetics. Planning the pre-prosthetic surgery to remove the palatine torus includes creating study models and surgical guides. Prototyping technology with three-dimensional printing has been used in Dentistry to obtain models, create guides and plan surgeries, replacing traditional methods with some advantages. We report a clinical case of palatal torus removal in which virtual planning techniques and prototyping of oral models were used using three-dimensional (3D) printing, which were used for planning the pre-prosthetic surgery. Computed tomography, the study and manipulation of images to create the model provide important information about the anatomy of the site and the simulation of surgery carried out on the printed model allows training in surgical technique, increasing predictability at the time of the patient's surgery. The use of 3D models allows training and adaptation of the generic technique to the specific clinical case with the preview of details and surgical difficulties, resulting in greater technical precision and a reduction in real surgical time.
