PART III Basic Principles of Practice BASIC PRINCIPLES OF PRACTICE CHAPTER IX ARRANGEMENT OF THE TEETH AND ALVEOLAR PROCESS ANATOMICALLY CONSIDERED The foundation of all training calcialated to fit one to enter the practical field ofOrthopedic Dentistry must lie in a perfect knowledge of natures anatomical arrange-ment and occlusion of the teeth, and the form and structure of the alveolar process. This is most perfectly described in the incomparable work Dental Anatomy,by Dr. G. V. Black, who has kindly permitted the re-publication of it in this chapter. ARRANGEMENT OF THE TEETH Fig. The upper teeth are arranged in the formof a semi-eUipse, the long axis passing be-tween the central incisors. In this curve, thecuspids stand a little prominent, giving a full-ness to the comers of the mouth. In differ-ent persons there is much variation in theform of the arch within the limits of thenormal. Occasionally the bicuspids and mo-lars form a straight line, instead of a curve,and frequently the third molars are a littleoutside the line of the ellipse. In the ex-amination of casts of the most perfect den-tures, it is found that the two sides do notperfectly correspond, and that certain teethdeviate slightly from the perfect line. Theincisors are arranged with their cutting edgesforming a continuous curved line from cuspidto cuspid, and this line is continued over thecusps of the cuspids and the buccal cusps ofthe bicuspids and molars to the distal surfaceof t
