Linear occlusion.

occlusal design. It is intriguing because of its simplicity and its remarkable success in practical usage. By incorporating an extremely effective chewing mechanism with linear stability in the occlusion, an entirely new combination of prosthetic advantages is achieved. Linear occlusion definitely provides a stabilizing effect on the denture bases during function. Heretofore, occlusion for full dentures has been limited to three-dimensional (cusp) occlusion and two-dimensional (flat plane) occlusion. When the combined points of contact on the occluding surface form a flat plane, the tooth is two-dimensional. When any portion of the occluding surface is above another portion of the occluding surface, the tooth is three-dimensional All of the posterior tooth designs which have been available fall into either one of these categories. Two-Dimensional: Fench, Halls inverted Cusp, Myerson & Sears, Tru-Byte Rational, Univac Bio-Mechanical. Three-Dimensional: Criterion, Myerson’s Synchronized, PilkingtonTurner. Tru-Byte Dentron, Tru-Byte Fournet, Tru-Byte Functional, Tru-Byte New Hue Diatoric, Tru-Byte 20 Degree, Tru-Byte 30 Degree, Tru-Byte 33 Degree. Univac Nuform, Univac NIC, Verident NIC. Linear occlusion allows us to complete the geometric classification of occlusion by providing a one-dimensional occlusal design. As such, it provides the practitioner with a valuable new tool to cope with prosthetic problems. Linear Occlusion
