My improved arrangement is such that crevices, cracks or the like, in'which par-f ticles' of food or 10ther"foreign matter may lodge, are substantially eliminated; undue, strains on the permanent teeth, to which the "attachment pplied, are avoided; and there may/be 'Such l l ni between the bridge work and the gum thatthe latter maintained in proper condition,

it being understood that this term is jfem- Y a 1 manent teeth. Betweentl1e permanentteeth b are removable or artificial teeth d fixed a particular band adapted to partially iencircle I the "crowns onythe perm'anentrteeth. In the-present instance, each clasp is'jshovv'n, as havinga pairof arms 10adaptedtofclosely straddle a crown, the clasp,'by preference,r
being made of a suitable resilient mate j rial ,so I that the arms may spring slightly "apart when slippingtheclasp onto-a crown 'orremo'vingthe same therefrom and softhat v the arms will hub the crown when the clasp is inposition, Each of the clasps may have V 1 a tang or wing '11 by'means of which it is secured to the bridge 6 or' the clasps may be i formed integrally vwith'the plate. 7
I In accordancewithi'the present invention, i
80 vobvious that, the denture or'. orthodontia ap -j ,pli'ance'maybe of any-desired rorm depena 1 ring uponv conditions, and-that the denture 1 :m ay beheld in placeiby a single clasp. For,
7 each arm of a clasp is provided with a depression or recess 12, and these recesses are adapted to closely receive similarly shaped projections 13 on opposite sides of a Crown 0. By preference, each arm is further provided with a second recess or depression 14 .which, when the clasp is in place on the crown, is adapted to, receive or fit over a respective projection 15 on the crown. Itis desirable that these depressions 14 be immediately beneath the recesses 12 and that they be opened at their lower edges so as to 'form grooves, so to speak. The projections 15 are immediately below the projections 13. It will be observed that, with this arrange merit, the clasp may be readily slipped into 1 place on the crown for, when it is moved down. into position, the grooves 1 1 will accommodate the projections 13,:resulting in the arms being slightly c'ammed apart so that the clasp willslip oved the projections eign matter cannot lodge therein.

VVhen the clasp is in final I position, the projections 13 fill the grooves or depressions 1 1 so that food or other for- 7 Owing to the fact that the arms are hugging the crown," and the projections 13 are/engaged ing action in one directionand a pivotal action in the other direction.
For the purpose of relieving excessive stress-on the gum tissue, particularly where the bridge or plate is relatively small, each clasp may be positively held against moving down to too great an extent on the crown with which it is associated. For example, each crown may be provided on opposite sides with a projection or boss 17 and each arm may have in its lower edge a notch 18 adapted to'receive one'of these bosses. By preference, the bosses 17 fit closely within the recesses so as to eliminate spaces in which food or the like might lodge.
The projections and bosses of the crowns are economically formed by bending the metal of the crown outwardly by means of suitable The top or end surface of the boss 17 ledge, and the upper or inner edge of the notch 18 securely seats upon this ledge. Thus, there is no tendency for the ledge to cam thearms apart. 1 I
