An overjet is the horizontal distance between the upper and lower front teeth. In permanent dentition, the ideal overjet is typically between 1-3mm. This allows for proper function and aesthetics of the mouth. 3-5mm (option B) would be considered excessive and can lead to bite problems and risk of injury. 0-2mm (option C) may not provide enough space for the lower teeth to function properly. 2-4mm (option D) is also considered excessive and can lead to an increased risk of injury. It is important for the overjet to be within the ideal range to ensure proper function and alignment of the teeth.
