Transactions of the odontological society of Great Britain . plate is too large to pass betweenthe approximated crowns, or when in positionis very loose, from the gaps which must existbetween the plate and the necks of the naturalteeth. Such cases are usually treated — if treatedat all—by inserting a plate which covers alarge portion of the mouth, in order to insuredue steadiness and safety. So large a plateis a source of such inconvenience to the wearer,that in many instances its use is abandoned,and the patient is, therefore, frequently dis-suaded from having such a gap filled up at all. FOR THE RETENTION OF ARTIFICIAL DENTURES. 11 Now I think it will be admitted that thesmaller we can make our plates—having dueregard to their safety, steadiness, and ease ofinsertion and removal—the better. The patientwill experience much greater comfort, and lessdamage can be done to teeth in remote por-tions of the mouth. If we make use of the locking bands justdescribed, the treatment of such cases becomeseasy. A plate no larger than the space, but. Fig. 6. Showing method of inserting plate from the lingual aspect of theteeth, to dovetail into wedged-shape space, the locking bands being open. which it accurately fits, has ordinary bandsadjusted to the lingual surface of the toothin front and behind the gap. Two locking baudsare then adapted to the labial surfaces of theseteeth in such a way that, when open, theyare no wider than the width of the gap. Sucha plate, when placed in the mouth with thebands open, may be dovetailed into positionby pushing it outwards from the lingual towards 12 ON SOME MECHANICAL DEVICES the buccal surface, and is secured by closingthe bands, the overhanging crowns effectuallypreventing any upward displacement. Instead of a back tooth, a front one maybe lost, leaving the same wedge-shaped spacewith the base towards the gum, and needingthe same large-sized plate to carry the artificialsubstitute. This may, however, be obviated
