Other objects will hereinafter appear. i
The preferred embodiment of the invention in posterior teeth is illustrated by Figs. 1 to 6, inclusive, of the drawings; and in anterior teeth, by Figs. 7 to 13, inclusive.
Fig. 1 is a perspective view of a porcelain posterior tooth with a tube baked therein; Fig. 2, a similar view of said tooth with the metal connecting member mounted thereon; Fig. 3, a perspective view of the metal backing for said tooth; Fig. 4, a side elevation, partly in section, of the tooth and backing adjacent each other; Fig. 5, a partly sectional side elevation of the united tooth and backing; and Fig. 6, aside elevation of the tooth and backing on a gu Fig. 7 is a perspective view of a porcelain anterior tooth with the'tube baked therein; Fig. 8, a, perspective view of the metal backing; Fig. 9, a perspective view of said tooth with the metal connecting member mounted thereon; 10, a. diagrammatic view illustrating the connection of the. artificial teeth to natural teeth: Fig. 11, av partly sectional side elevation of'said tooth. and backing adjacent: each other; 12,1 partly sectional side elevation of the unitedtooth and backin and Fig. .13, a. side .elevationof the tooth: andbacking on a sum.
, Referring to Fig. I. the porcelain tooth is indi-- cated at 1. It hasa first lingual fiat surface 12,. extendin from its occlusal surface. o bi in ge. .3, and. a second flat surface 4 extendin r aid first surface '3. and inclined linguall therefrom. In the, tooth. l are. a pair cfsockets 5 opening at the first surface 2 and extending inwe rd y therefrom. 'lhese' s ck ts 5 are enlarged nward1y;f0r a; purpo e which Willhere na ter app n thin the teeth 1,. opening atzth sur faces an 4 and extending inwardly ther from is n i rn y hre ded; time 6: T e. sinsiyal surface 7- of the tooth 16(Fig.6),.-. 1 n th 'sur ece 2 and 1: f t tooth isp s n i e-memher 8, (F g-.2); mad o Pl t num.
steel or the like, and having openings 9 and a tongue 10. The openin s 9 are alignedwith the: sockets 5, and the tongue 10 is substa tially degre tail-shaped. The connecting member 8 is connected to the tooth 1 by screw 11., passin through-theconnecting mem er 8 and'screwed. intothe'tube' :6. p
The metal; bac in 12, shown by lFis..- h p o fit and; to be coexte sive with the. suf-l faces land 4, and hasa pair of p ns l3 to. pass throughthe openingsb in the connecting member8 and into the sockets 5 in the tooth 1; and a groove 14 for the reception of the connecting member 8.
The mounting of the artificial posterior tooth just described between natural teeth is substantially the same as the mounting of the artificial anterior tooth, as shown by Fig. 10. In Fig. 10, anterior natural abutment teeth are indicated at 15, the roots thereof at 15a, the gum therebetween at .16, the backing at 30, and an artificial tooth at 18. This view illustrates; the mounting of two artificial teeth between two natural teeth of the front portion of the lower jaw. One of these artificial teeth has been removed to illustrate its section of the backing. Backing will comprise a single section or several sections, depending upon the number of artificial teeth to be mounted. These sections are soldered together, and the end sections are then soldered to crowns, inlays, or other metal attachments shaped to fit he I 18; opening atfiand extending inwardlyfrom the the machine work that must be done on the? porcelain tooth, and it may be done'quickly and easily without chipping or fracturing the porcelain. V V
The connecting member 8 (Fig. 2) is then applied to the surfaces 2 and4 so that the openings 9 are aligned with the sockets 5. The. screw 1 11 is then passed through the connecting member8 and screwed intoizthe tube6. 5 Cement is then.placed -upon.-. the.surfaces 3 and4 and irrthe socketssb. Themetal backing 12 (Fig. 3) having been soldered to the metallic parts of 1 the bridge-work (as suggested by Fig. 10); the porcelaintooth l,- with the'metal connecting member thereon; is moved into engage-' ment with the backing 12- so: that the pins 13 pass :through' the openings .9 in the connecting member 8 and into thesockets Sintd tooth 1, andthe tongue 10 of the metal connecting member 8 enters the groove 14 inthe metal backing 12. The partsare then held' together until the cement-therebetwe en sets. 1
Should the porcelaintooth' 1-be chipped or otherwise injured" so that its removal is desired; the cement bond between the backing'12, member 8 and tooth l 'may be broken by moving the tooth on the backing. The tooth may then be removed from the backing,' the backing cleaned, and the new tooth. cemented on the backingto take the place of the old. It will be noted that it i's'not neces'ary to disconnect the backing from the bridgework in order to replace the tooth.
Referring now to "Figs. '7 through 13, inclusive,
illustrating the'anterior tooth, the tooth is indicated at 18;" It has a first'lingual surface 19 (Fig. '7), extending from its incisalor biting edge 20, and a second surface 21, extendingfrom' the first surface19 and'inclined lingual-1y therefrom. In the tooth 18 opening atand extending inwardly from the surface 19 is a socket 22. This socket is enlarged inwardly. Within the tooth surfaces 19 and 21'is a metal tube 23. The gingival surface of this tooth is indicated at 24. It is shaped to fit the gum 16, as shown by Fi 13.
In Fig. 9, the metal connecting member is indicated at 26. It has an opening 27 aligned with the socket 22 and a tongue 28. The member 26 is held on the tooth 18 by a screw 29 passed through the member 26 and screwed into the tube-2 3. V
Thebacking 30 (Fig. 8) base. pin 31 to pass through the opening 27 and into socket 22, and the groove 32 for the reception of the connecting member 26.
The making and mounting of the anterior tooth on its backing is the same as that of the posterior tooth above set forth.
The invention is not limited to the preferred embodiments herein described.
I claim: I Q I I l 1. The combination of a porcelain tooth having afirst fiatlingual surface extending from its biting edge, a socket openingat and extending in-- wardly from said first surface, and a second flat surface extending from said first surface and inclined lingually therefrom; a metal tube in said tooth opening at and extending inwardly from said lingual surfaces; a-metal connecting'member on said surfaces and having an opening aligned with said socket, and a tongue; a screw' connecting said connecting member to' said tube; and a metal backing coextensive with said surfaces and member and having a pin extending through the opening in-said member'and into the socket in said tooth, and a groove for the receptionof the tongue of sai'd'member; said tube, member and backing being remote from the gingival surface of said tooth."
2. The combination of a porcelain tooth having two surfaces at an angle to each other, and a socket opening at and extending'inwardly from one of said surfaces; a metal tube in said tooth; a metalconnecting member on said surfaces and having an opening aligned with the socket in said tooth,"and a tongue;- a'screw extending through said member and into" said tube; and a metal backing coextensive with said surfaces and member and having a pinextending through the opening in said member and into the socket in said tooth, and a groove for the reception of the tongue of-said member; said tube, member and backing being remote from the gingival surface of said tooth.
