I m p l a n t a n d o r t h o d o n t i c t r e a t m e n t Figs. 5a–c Virtual plan: frontal (a) and sagittal views (b); virtual stereolithographic surgical template (c). Figs. 5a & b b Fig. 5c a c After orthodontic treatment, the patient under- went a preoperative cone beam computed tomog- raphy (CBCT; CRANEX 3Dx, SOREDEX, Tuusula, Finland) scan, and diagnostic impressions were taken using a polyether material (Impregum, 3M ESPE, Seefeld, Germany) with a custom open tray (Diatray Top, Dental Kontor, Stockelsdorf, Ger- many). Furthermore, model casts were poured in Type IV stone (Techim Super Stone, Techim Group, Milan, Italy) and a diagnostic wax-up was made. The STL files derived from the scanned model and wax-up were merged with the DICOM data derived from the CBCT scan in the same virtual implant planning software (NobelClinician, Nobel Biocare, Kloten, Switzerland). Virtual planning was completed by defining a prosthetically driven implant placement. Owing to the reduced space between adjacent roots, a 3.0 mm implant was planned (Osstem TSIII, Osstem, Seoul, South Korea). After careful functional and esthetic eval- uation and final verification, the approved virtual plan was transmitted to a milling center (Nobel Biocare) for the production of a stereolitho graphic surgical template (Figs. 5a–c). 12 Volume 3 | Issue 1/2017 Journal of Oral Science & Rehabilitation
