Which of the following is not an advantage of using non anatomic teeth?

Non Anatomic Teeth These teeth have 0 degree cusp angles. These designs evolved to over-come the disadvantages of the normal anatomic teeth. These teeth do not provide balanced occlusion. Balanced occlusion in  dentures with these teeth is obtained by balancing ramps and compensatory curves. Bilateral and protrusive balance is not possible with a purely flat occlusion.
