The patient presented with skeletal class III malocclusion and posterior edentulism. The patient had difficulty in chewing and wanted to improve his chewing ability.Implant-supported prostheses lack periodontal mechanoreceptors and therefore tend to be subjected to excess lateral force, which may cause clinical complication. To minimize heavy lateral force the implants were placed so that they could be vertically loaded . To achieve this, a cross-bite was established in the posterior. Occlusal adjustment was performed carefully to guide the chewing force to the axis of the prosthesis.In a case of skeletal class III malocclusion, the establishment of a cross-bite using implants is biomechanically rational and therefore produces a predictable outcome.
