Excerpt from The Twentieth Century Mould Book: Containing Illustrations and Measurements of Twentieth Century, Dentsply, Solila Teeth, Crowns and Dentsply Facings; Together With Much Useful Information Concerning Their Manipulation Many dentists have failed to make use of the very important mechanical advantages offered by the varying lengths Of bite, shut and ridge-lap. This book makes these advantages plain. They make it much easier for the dentist to select teeth to conform to the mechanical requirements Of the various cases. Behind each Mould are definite plans and careful study. Each Mould is made to fill a clearly recognized need, to enable dentists to, fit a particular case with.a tooth which not only harmonizes in outline with the face, but meets the mechanical requirements, as determined by the comparative depth of ridge and length Of lip, and the length Of the ridge from one tuberosity to the other. It will also be easy to select from among the moulds Of proper width, one which will permit the pins to set on the ridge, the incis'al edges of the anteriors to come at the labio-incisal angle of the trial plate and that part Of the plate exposed in laughing to be occupied by the teeth There need never again be need for ordering teeth as large or small. Exact orders for exact needs should be the rule. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
