The patient, a 16-year-old male, presented with an asymptomatic periapical lesion on tooth 46 (lower right first molar), which had been previously endodontically treated. He was already undergoing orthodontic treatment on the maxillary arch, with mandibular brackets planned after the prosthodontic restoration was completed.

The treatment plan included:

•  Endodontic retreatment of tooth 46
•  Fiber post restoration
•  Digital impression with the UP610 for a chairside CAD/CAM long-term provisional crown
•  Definitive crown restoration to be completed after orthodontic treatment concludes

The decision to place a long-term provisional rather than a definitive crown was deliberate: the upcoming orthodontic treatment on the mandibular arch would alter the patient's occlusal relationships, making a final restoration premature. A durable provisional would protect the endodontically treated tooth throughout the orthodontic phase while preserving the option for an optimized definitive crown once the occlusion stabilized.

After completing the endodontic retreatment and fiber post placement, the clinical team used the UP610 to capture digital impressions of both arches for the provisional crown design.

This is where the case became a real-world test of the UP610's orthodontic scanning capability. The maxillary arch was fully bracketed with metal brackets and archwire, while the mandibular arch presented the prepared tooth 46 alongside the adjacent dentition. The scanner needed to handle two very different surface types in the same session: the highly reflective metal hardware on the upper arch, and the prepared tooth structure on the lower arch.

The UP610 captured the metal brackets and archwire with full detail — no artifacts, no dropout areas around the reflective metal surfaces. The true-color rendering preserved the visual distinction between bracket metal, enamel, composite, and gingival tissue, giving the clinician immediate on-screen verification that the scan was complete and accurate.

A closer look at the prepared tooth 46 confirmed that the fiber post area and remaining tooth structure were captured with sufficient detail for crown design — including the margin line and the transition from tooth structure to the post restoration.

The scan data was exported from the SOREAL platform and imported into exocad for crown design. This step is worth noting: the UP610's open file format output (STL, PLY, OBJ) allows seamless integration with third-party CAD software — clinicians and labs are not locked into a single ecosystem.

In exocad, the provisional crown was designed with full anatomic contours, with the software's antagonist analysis verifying the occlusal relationship against the bracketed upper arch. The design was finalized and sent to the milling unit for chairside fabrication.

The provisional crown was milled chairside from Lava Ultimate (3M), a resin nanoceramic (RNC) block. For this restoration it served as a long-term provisional: durable enough to withstand function and protect the endodontically treated tooth throughout the orthodontic phase, while remaining straightforward to remove and replace when the definitive crown is fabricated after the occlusion is finalized.

The crown was cemented with G-CEM ONE (GC) under rubber dam isolation, following air-abrasion and primer surface treatment of the intaglio — consistent with the adhesive cementation protocol used across the department's digital workflow.

The long-term provisional crown on tooth 46 achieved a natural integration with the surrounding dentition. The occlusal anatomy milled from the exocad design provided functional contacts, while the resin nanoceramic delivered an acceptable aesthetic match for the provisional phase.

Following the prosthodontic restoration, mandibular orthodontic brackets were placed — confirming that the provisional crown's design and material allowed for bracket bonding on the adjacent teeth without interference. The patient will continue orthodontic treatment, with the definitive crown planned once the occlusion has been finalized.

Metal brackets are not a barrier. The UP610 captured metal brackets, archwires, and ligatures without artifacts or scan dropouts. For practices that see orthodontic patients needing restorative work, this removes the concern that digital impressions won't work around fixed metal hardware.

Clinical decision-making drives material choice. A long-term provisional was the right call here — not because a definitive crown couldn't be fabricated, but because the patient's occlusion will change during orthodontic treatment. The digital workflow made it straightforward to scan, design, and mill a durable provisional chairside, with the option to repeat the process for the definitive crown later.

Open format means open choices. The scan data moved from the SOREAL platform to exocad without friction. Clinicians and labs using third-party CAD software can work with UP610 scan data (STL, PLY, OBJ) in their existing design environment — no ecosystem lock-in.

Three cases, one consistent workflow. This is the third clinical case from the UP3D–UMFVBT collaboration, following a post and core with zirconia crown case and a chairside provisional on an orthodontic patient published earlier. Across all three cases — different clinical scenarios, restoration types, and materials — the UP610 and SOREAL platform delivered a consistent, reliable scanning and data-management workflow.
