Finite element study on the effect of bruxism on the fracture resistance of maxillary zirconia fixed partial dentures with varying anterior inter-implant distances

It is recommended that clinicians construct maxillary zirconia FDPs with a broader implant distribution and a cusp inclination of (≤ 15º) for better outcomes in patients with bruxism. This configuration enhances prosthetic stability and reduces stress, thereby increasing longevity. Clinical protocols may encompass strategic implant placement, reduction of cusp height, and individualized occlusal design.
