134 ON THE CHEOPLASTIO METHOD 



direction the tooth or teeth to be regulated re- 

 quire to be drawn, as a few minutes will enable 

 you to alter the position of the pin, if the power 

 is applied from the palate surface, or to perforate 

 the band passing in front, if it is from the labial 

 portion; or should it require a new means by 

 addition of metal, it is soldered so accurately and 

 with such expedition as to command in these par- 

 ticulars the whole field of mechanics in regulating. 

 This will be readily understood when the principle 

 is comprehended of obtaining the plate or band. 

 Having a good impression, you model your plate 

 to rest in a certain position, holding it by as 

 many points of attachment as you think proper to 

 grasp by clasps or ligatures, as may be preferred, 

 securing at the same time the substance of metal 

 upon the grinding surfaces of the molars necessary 

 to keep the teeth from antagonizing during the 

 reduction of the irregularity, and of course the 

 piece is delivered precisely as you have modelled 

 it, with the greatest opportunities for any subse- 

 quent alteration.' 



If cheoplasty had no other especial advantage, 

 its superior use in regulating would command 

 from you, gentlemen, its adoption for such pur- 

 poses. But it commends itself in many other 

 directions, none greater, however, than the un- 

 qualified superiority of adaptation to any given 

 surface. In all pieces in which springs or clasps 

 are used, the small size of the plate which may be
