Initial situation
A 38-year-old female patient presented to the dental office reporting discomfort when smiling, due to the absence of both upper second premolars (Figs. 1-3).
Clinical examination revealed tooth #16 with an intraradicular post and preparation for a crown, which was missing. In the adjacent quadrant, a cavity was noted on the distal surface of tooth #14. Overall, the patient exhibited healthy periodontal conditions. She is a non-smoker and does not present with any comorbidities or systemic health issues. CBCT imaging showed no signs of acute infection, and adequate bone quality and quantity at both sites. Additionally, a residual root was identified at site #15 beneath the already healed gingiva.
Treatment planning
The patient’s upper and lower arches were scanned using the Straumann® SIRIOS™ system. The scans, along with the DICOM files from the CBCT, were sent to Straumann® AXS™ – Smile in a Box® for treatment planning, surgical guide design, and 3D printing of the model and surgical guides (Figs. 4-6).
