Partial dentures incorporating onlays in the treatment of a complete anterior overbite

Incorporating onlays onto partial dentures, that is occlusal or incisal rests extended to cover the entire occlusal or incisal edges, can be used successfully to treat overbite. This case study describes its use in a patient with a complete anterior overbite together with severe tilting of some of the maxillary molar teeth. Early tooth loss, which had not been restored, was probably a significant aetiological factor in the patient's condition.
