Losing the bite height or the vertical dimension of occlusion disturbs the function and aesthetics of each patient. Its reconstruction is successfully carried out through series of methods which make it easier to determine the new vertical dimension of occlusion. Detailed diagnosis and caution are needed while carrying out the reconstruction for it to be successful. The collapse of the vertical dimension of occlusion is due to two reasons. The first reason is the general abrasion of all teeth due to bruxism. The second reason is the loss of the back region's teeth without their compensation. The methods we use are numerous and are used in combination with each other because each one is not sufficiently precise on its own. According to one’s experience, each practitioner decides which methods he will be using. Beside the vertical dimension of occlusion it is essential to know and determine the vertical dimension of physiological rest position, as well as the horizontal relationship of the maxilla and the mandible, that is, the centric relation and the maximum intercuspidation. The reconstruction procedure can be performed by occlusal rims bumper or wax-up and mock-up. When changing vertical dimension of occlusion, it is important to take into account certain criteria, the possibility of errors and possible unwanted consequences due to the change of vertical dimension of occlusion.
