This patient had failing implants in the lower right side which were ultimately removed. The implant crown #12 continually loose. It was remade twice by his dentist but continues to loosen. He uses a lower RPD. Note the overbite and diastema that has been increasing over time. A clear case of posterior bite collapse, primary occlusal trauma (patient a bruxer / clencher) and malocclusion. How would you treat this patient?
