DETAILED DESCRIPTION

[0016] The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, or uses. It should be understood that throughout the drawings, corresponding reference numerals indicate like or corresponding parts and features.

[0017] Referring to FIGS. 1-5C, there is shown an illuminated dental prop embodiment 10 including two major components, a bite prop 12 and a light assembly 14. The light assembly includes as its main components a housing 18 and a lighting package 20. The housing can be formed from a variety of materials sufficient to protect the lighting package secured within, such as lightweight thermoplastics, thermosets or silicone, by way of non-limiting example. The light package typically includes lighting electronics including a circuit board (not shown), battery and switch contacts, a battery 42 and one or more LED lights 62. The lighting assembly is packaged such that the electronics, battery and LED lights are contained therein so that the entire light assembly can be sterilized without risk of damaging the components. Sterilization can be accomplished using ultra-violet radiation, chemical application and/or autoclaving by way of non-limiting example.

[0018] As shown, the light assembly housing 18 has an exterior wall 44 defined by a front wall 46, rear wall 48 and opposing top and bottom walls 50, 50a, respectively. Disposed along walls 50 and 50a and the rear wall 48 is a peripheral flange 52. The flange 52 includes recesses 54, 54a generally located near the front wall which receives the tabs 26 projecting from the interior wall of the bite prop. The flange 52 includes wings 56, 56a located proximate to the front wall 46. Optionally, the flange may also include a projection 58 which fits into a pocket 38 located along the interior of the transverse portion. The light assembly may include a translucent cover 60 through which the light generated by the light assembly is transmitted. If the cover is not translucent then the LEDs will extend into cutouts in the cover so as to allow for the free transmission of light. The light assembly will also typically include an on/off button or switch 64 connected to the lighting electronics to allow the battery to energize the LEDs during activation. The switch may be of the type that allows for different levels of activation of the LEDs. For example pressing once one or more of the LEDs are activated, by pressing a second time the LEDs are further activated and a third pressing activates the LEDs still further. This arrangement allows for selectively varying the light intensitt, e.g. bright, brighter and brightest.

[0019] The bite prop 12 has a substantially C-shaped body including first and second legs, 16 and 16a, respectively, extending at an inclined angle from the transverse portion 22 to define an open area 40 which ultimately is occupied to some extent by the light assembly. This slight angle allows the light assembly to be more easily inserted into the open area 40 for engagement with the bite prop. The bite prop also includes an external wall 28 extending along the transverse portion 22 and first and second legs 16, 16a of the dental prop 10. Optionally, the external wall is recessed along at least the first and second legs thereby providing a trough 30 to preclude lateral movement of the teeth during use. Still further, the trough 30 may be lined, e.g., over-molded, with an elastic material 32 or simply roughened, thereby providing an enhanced tooth-engaging surface. Thus, when the dental prop 10 is positioned over the patient's teeth at the back of the mouth, with the transverse portion near the back and the first and second legs projecting toward the front of the mouth, the extra grip provided along the tooth engaging surface, in association with the patient's natural instinct to close their jaw, helps keep the prop fixed over the teeth.

[0020] The interior wall 24 of the bite prop which extends along the transverse portion 22 and the first and second legs 16, 16a is sized to tightly accommodate the light assembly 14 when it is fully inserted therein. Projecting inwardly from the interior wall 24 along the first and second legs are a plurality of spaced apart partitions 34 which define slots 36 for hosting the flange 52 of the lighting assembly housing. As shown in FIGS. 3A-3C, the lighting assembly can be repositioned along various locations within the bite prop 12. As further illustrated in FIGS. 5A-5C, when the light assembly is located in the forward position as depicted in FIG. 5A, the light array tends to be widest. In the middle position, the light array is narrowed since the light is somewhat blocked by the first and second legs 16, 16a of the bite prop as shown in FIG. 5B. An even narrower array is provided when the light assembly is positioned in the most reward position. In this position, the light array can be focused in a narrower area along the opposite side of the patient's mouth which, during certain dental procedures, can be useful. As can be appreciated, when the light assembly is located most rearward as shown in FIG. 5C, the area 40 between the first and second legs of the bite prop is largely open which also can be useful if the dental professional needs additional room to work within the oral cavity. Likewise as can be appreciated the housing of the light assembly may push the patients check outwardly to provide more room in the oral cavity.

[0021] An enhanced locking feature is also offered by one or more tabs 26 extending from the interior wall 24 which mates with a complementary recess 54, 54a provided along the flange 52 of the light assembly. As shown, it is preferable that there be a tab 26 disposed on each of the first and second legs 16, 16a, between the partitions 34 which can mate with the recess 54, 54a of the flange 52 for additional security of the light assembly to the bite prop. While not shown, it should be understood that the interior wall may have at least one recess and the exterior wall of the light assembly may have one or more locking tabs. As with the light assembly, the bite prop is also sterilisable using an appropriate technique.

[0022] The light assembly may include a rechargeable battery via direct charging or using an induction system or may be readily replaceable. Optionally, the light assembly may be replaced with another light assembly when the charge of the battery is exhausted. Under still further embodiments the light assembly housing may be selectively open and closed to replace the battery as needed

[0023] The description of the invention is merely exemplary in nature and, thus, variations that do not depart from the gist of the invention are intended to be within the scope of the invention. Such variations are not to be regarded as a departure from the spirit and scope of the invention.
