Two case reports stereolithographic model’s role as a pre-surgical diagnostic and communication tool.

Objective: This study evaluates the effectiveness of stereolithographic models in diagnosing and treating complex dental inclusions, analyzing their impact on surgical and orthodontic planning and the reduction of intra- and post-operative complications.Materials and Methods: Three-dimensional stereolithographic models were created from CBCT scans and printed in transparent resin. In the first clinical case, a 15-year-old female patient presented with complete inclusion of two horizontally impacted upper canines. The 3D model enabled precise localization of the teeth, guiding extraction through a vestibular approach and targeted osteotomy. In the second case, a 10-year-old had a malocclusion and was absent in 1.1 tooth. An OPG confirmed the presence of two supernumerary teeth: canine-like and rotated mesiodens. A 3D-printed model using a CBCT scan was created for surgical planning.Results: Stereolithographic models facilitated accurate diagnosis, detailed surgical planning, reduced operating time, and minimized risks. During procedures, they improved flap design, lesions, and identification of dental structures. Additionally, they promoted better communication with patients, reduced parental anxiety, and made outcomes more predictable. However, limitations related to cost and dependence on the surgeon’s expertise were identified.Conclusions: Stereolithographic models proved to be practical tools for diagnosis and interventions, improving precision and communication. Despite technological and cost-related limitations, the evolution of 3D printing promises broader applications in the medical field.
