A 38-year-old female patient presented to our dental practice complaining of discomfort in the maxillary left area. The clinical examination revealed a fractured ceramic crown on the posterior abutment (tooth #27) of a three-unit bridge (from tooth #25 to tooth #27) placed seven years earlier by her previous dentist (Fig. 1).
The first step was to remove the old bridge and to check the abutment preparation. A temporary resin bridge was placed with Temp-Bond (Kerr; Fig. 2).
One week later, a digital impression was taken using the DEXIS IS 3800 intra-oral scanner (Fig. 3) and sent via DEXIS IS Connect to the dental laboratory for the design and milling of a new zirconia bridge.
Four days later, the new layered zirconia bridge was sent to the practice along with 3D-printed models (Fig. 4).
The final zirconia bridge emphasises the quality and precision of a digital workflow (Fig. 5). After the try-in, the final restoration was cemented in the mouth using glass ionomer cement (Fuji I, GC). Six weeks later, the patient came back for a postoperative check-up, during which perfect contact points and good adaptation with the soft tissue were seen (Fig. 6).
