Findings of initial panoramic radiograph. Insufficient length of filling material of teeth 23, 24, 25, 26, 27, 15, 16, 45, 44, and 35. Old long fixed prosthesis included teeth 23, 24, 13, 14 15, and 16. Absent anterior teeth (22, 21, 11, and 12).

The initial clinical findings demonstrated a prosthetic rehabilitation of a 26-year-old fixed partial denture from the right upper cuspid to the left upper cuspid (Figures 1 and 2) and a medial intraosseous fracture of the left upper cuspid (Figure 3).
Clinical findings prior to treatment: inadequate prosthetic reconstruction in the anterior upper jaw.

The initial clinical findings demonstrated a prosthetic rehabilitation of a 26-year-old fixed partial denture from the right upper cuspid to the left upper cuspid (Figures 1 and 2) and a medial intraosseous fracture of the left upper cuspid (Figure 3).
In this radiograph, there is a mesial fracture on the cervical third of tooth 23. Considering the long span of the fixed prosthesis, it could have overloaded the canine. In addition, insufficient length of the intraradicular retainer could have promoted inadequate tension distribution along the root. Also shown is the fixed partial denture supported by teeth 23 and 24. Tooth 25 presents a provisional prosthetic crown supported by a prefabricated pin. All teeth (23, 24, 25, and 26) show unsuccessful endodontic treatment.

After instructions on oral hygiene and plaque removal, the original prosthesis was replaced by a removable temporary partial prosthesis (Figure 4) and the medial fracture of the left upper cuspid was surgically extracted (Figure 5).
The medial fracture of tooth 23 was surgically extracted.
