The etiology of osseous deformities of the head, face, jaws and teeth . ^ the crowded conditionof the teeth and extend farther from the median line thanotherwise. The loss of the third molars by extraction ornon-development Avould prevent the other side from increas-inof to the natural size. THE HEAD. FACE, JAWS AND TEETH 313 Second. The relation of the upper teeth to the lower articulation of the inferior maxilla with the cranium isso remote, and the contour of the two bones so unlike, thatuniformity of bone-structure cannot be looked for. Whenwe consider the complexity of the development of bone-tis-sues, first of the maxillary bone, then of the alveolar process,and lastly of the two sets of teeth, it is a wonder that har-mony ever prevails. ASYMMETRY OF THE MAXILLARY BONES. HmkelVs Deformity.^—When we examine models of thesuperior maxilla after absorption of the alveolar process has. Fig. 95. taken place, we observe that in the cuspid and bicuspidregion, high above the alveolar border, a marked depressionexists on either side. Fig. 95 shows a base-plate which hasbeen formed over such a model. The plate is more depressedat the left than at the right side. This peculiar deformit} isfamiliar to the operator who arranges teeth and waxes upplates for the purpose of restoring the contour of the closer inspection of the model it will be seen that thereis an asymmetry of the lateral halves of the maxillary Dr. Haskells assistance, I have examined 298 models, *I have named this deformity Haskells Deformity, for the reason thatDr. Haskell called the attention of the profession to this peculiar condition ofthe maxillary bones years a?o, personally and through the journals, and says hehas found but one dentist who had observed it. 314 ETIOLOGY OF OSSEOUS DEFORMITIES OF tinding 268 out of the number with marked depression on theleft side, and twenty-four w
