Dental review; devoted to the advancement of dentistry. . he anchorage was displaced 2 mm., whichnecessitated the removal of the appliance four months subsequent toits adjustment; and the lower jaw could not take a more posterior position than mm. in advance of the position it occupied beforethe commencement of the operation. If absorption and deposition of tissue has taken place in theglenoid cavity, as my observations indicate, the removal of theappliance and relieving the back teeth from forcible occlusion by aslight addition to the anterior part of the bite-plate ought to producean absorption of the old socket, allowing the jaw to return to itsprevious backward position. Such an experiment was tried in CaseVI. In six weeks the lower jaw had moved backward mm. andoccupied its former position in relation to the occlusion of the in this case there was no bending of the neck of the con-dyle or any part of the lower jaw for the force—the muscles—neces-sary to produce such a change in the first instance continued to.

Consequently therewould have been no backward movement of the lower jaw. The jump-bite-bar, properly reinforced, was readjusted and thephysiological changes in the glenoid cavity required two and one-half months to produce such results as to permanently hold thelower jaw in the advanced position. In other words the filling inprocess in the glenoid cavity progressed at the rate of 2 mm. permonth.
