A practical treatise on mechanical dentistry . ed by Prof. Litch in connection withthe pin and plate attachments as a means of support for singlefront teeth, a method of attachment which, he says, although chieflyapplicable to the incisors, may be combined with crown or barbridges for molars and bicuspids. Fig. 516 represents a practical case in which the upper thirdmolar and first bicuspid (both without antagonizing teeth) wereutilized for the attachment of a bridge made of gold crowns withporcelain facings, to supply the loss of the intervening teeth. Fig. 517 represents the case as prepared
A practical treatise on mechanical dentistry . ed by Prof. Litch in connection withthe pin and plate attachments as a means of support for singlefront teeth, a method of attachment which, he says, although chieflyapplicable to the incisors, may be combined with crown or barbridges for molars and bicuspids. Fig. 516 represents a practical case in which the upper thirdmolar and first bicuspid (both without antagonizing teeth) wereutilized for the attachment of a bridge made of gold crowns withporcelain facings, to supply the loss of the intervening teeth. Fig. 517 represents the case as prepared for the bridge. A, 572 MECHANICAL DENTISTRY. the inner cusp of the bicuspid cut down to allow the placing of asufficiently thick crown-plate; B, a cylindrical undercut openingbetween the cusps for a retaining pin; C, the third molar madeuniform in size from neck to grinding surface, the latter also beingconsiderably retrenched; D, the crown-plate of a partial cap, madeof pure gold, soldered with 20-carat gold, and so constructed as Fig. to cover every portion of the tooth except its buccal surface, thefree edge passing up under the gum; E, a retaining pin adapted to>the opening, B; F, the gold cap for the molar. Fig. 518 represents the bridge anchored in position with oxy-phosphate cement. In the above case it will be observed that there is a Fig. 517.
