remove will depend upon circumstances. Those most decayed or nearest the deformity are the ones to be removed.

If a molar be badly decayed upon one side and a bicuspid upon the other, they should be removed. The condition of the teeth must, to a great extent, govern the operation. The dentist must decide in each particular case.

OCCLUSION.

While the model is the surest and easiest means of studying the occlusion of the teeth, the final conclusions can be drawn from the mouth; hence this part of the subject will be taken up here. It has been shown how the teeth, which are nearly always normal in size, work their way through the jaws and arrange themselves along the alveolar process. These teeth developing individually, it would be natural to expect that in occluding, the cusps of the teeth upon one jaw would not fit into the spaces in the teeth of the opposite jaw. This being the case, owing to the constructive stage of the alveolar process, the teeth will arrange themselves to conform to the articulation of the opposite teeth. The teeth all being in the jaws, and the mesial and distal surfaces of all the teeth touching, if the articulation be not perfect the teeth will rotate in their sockets. If spaces exist between the teeth, they will change their position until the proper occlusion is obtained.

We sometimes find the buccal cusp of one tooth striking the buccal or lingual cusp of the tooth opposite. In such cases one or the other is deflected in or out of the mouth. To correct these cases it may be necessary to extract a tooth, or cut away a cusp or the approximal surfaces of the teeth in order to cause occlusion. Lastly, an examination should be made of the shape and contour of the jaws, the height of the arch, and the inclination of the teeth, to decide upon a suitable impression cup and the best material for taking impressions.
