Dynamic forces: Many factors can lead to this, but most important are the support base and the bite. This is a long span to cover when starting with the canine, but do not expect the zirconium to fx. Likely clenching/grinding without occlusal guard/compliance . See the expert in reconstruction - Prosthodontist. Consider 2 crowns and 2 implants (12,13) with crowns and bite correction (lower arch). good luck.

Nocturnal bruxism: One contraindication for the use of zirconia is heavy nocturnal bruxism. See your dentist sleep test for detection of bruxism with its EMG capabilities and automated bruxism analysis prior to new bridge fabrication.
