De Rome, Twin Lakes, Wis. 1 Application February 5, 1944, Serial No. 521,195 3 claims. (01. 177-311) 2 This invention relates to a dentist’s bite de tector, namely, an instrument adapted for use by dentists to detect the proper bite relation to the upper and lower jaws. 1 . adapted to be placed around the head of the pa~ tient so as to pass over the temporal muscles, and a crown strip 9 secured to the head band and adapted to extend over the top of the patient’s head. The head band is extensible and contracti ble so that it may be ?tted to heads of diiferent sizes. Any suitable means may be provided for It is well known among the dental profession that too frequently patients do not take a proper bite and the dentist does not get the proper re lation between the upper and lower jaws. This this purpose, and as shown in 'Figs. 4 and '7 the results in making a false bite and the denture or overlapping ends it of the band are contained in dentures will not ?t the patient properly and a sleeve H and provided with rack bars l2 that must be modi?ed to make them fit and fre mesh with a pinion 13, mounted on a shaft 14 quently they cannot be used at all, thereby caus carried by a hand wheel 15. By turning the ing a ?nancial loss to the dentist, and a loss of hand wheel the dentist may adjust the head band time and annoyance to the patient. to snugly fit the head of the patient. The principal object of the present invention 15 Mounted for longitudinal adjustment on the is the provision of a, simple instrument, capable head ‘band are two sensitive electric switch units of detecting whether or not the patient is biting 16, It’ which have switch actuating buttons ll properly in the proper relation between the upper protruding through slots 18 in the head band and and lower jaws, and apprise the dentist by a adapted to engage the temporal muscles of the visible, audible or other signal, so that if the 20 patient. Conveniently the switch units may be bite is not proper he can admonish the patient mounted on slides 19 which have ?anges that vto bite properly. embrace the edges of the head band. This ar Another object is the provision of an instru rangement provides means whereby the switch ment of the above character which is adjustable buttons I‘! may be precisely located over the tem to accommodate diiferent sized heads and which 1.0 poral muscles of the patient. has adjustably mounted sensitive electric switches The switches l6, 16’ control an electric circuit for closing a circuit or circuits to the signaling for a signal 29 (see Fig. 5) in one form of the device or devices, whereby the dentist may prop invention which may comprise an incandescent erly locate the actuating buttons of the switches electric lamp. The lamp is in series with both in proper position over the patient’s temporal 30 switches as shown in Fig. 5, of which the circuit muscles so as to be acted on thereby. With these and other objects and advantages in view this invention consists in the several novel features hereinafter fully described and claimed. The invention is clearly illustrated in the draw ing accompanying this speci?cation, in which: Fig. 1 is a perspective view of the head gear parts of the apparatus. _ Fig. 2 is a detail horizontal section taken on the line 2—2 of Fig. 1. Fig. 3 is a detail vertical section taken on the line 3-3 of Fig. 2. may be traced from the source of electric supply 21 through conductor 22, switch IE5, conductor 22', switch it’, conductor 23, lamp 2%) and back to the source of electric supply 23. Instead of the battery shown, the circuit may be completed by plugging into an outlet of the house wiring ' system. In Fig. 6 two signals 20a, 26b are illustrated, each controlled by a switch, whereby when a 40 switch is closed the signal controlled thereby is activated. In use the head gear is applied to the patient and the head band is adjusted, and the switch head band of the head gear. units are adjusted along the head band to bring Fig. 5 is a diagrammatic view of one form of 45 the switch buttons into ?rm contact with the the electric circuit of the apparatus. temporal muscles and a bite plate or plates or Fig. 6 is a diagrammatic view of a modi?ed trying plate or plates having been placed in the form of the electric circuit; and patient’s mouth, he is requested to bite down on Fig. 7 is a detail cross section taken on the them.
