ProsthodonticsThe width of a palatal strap should not be less than 8mm to provide adequate rigidity and strength. A palatal bar is narrower (typically 4-6mm), while the strap is wider to distribute forces over a larger area. The increased width of the strap provides better support and reduces tissue pressure per unit area.
