Fig. 9 is a bottom view of a seventh shell dental appliance according to some embodiments of the present invention.
Referring to fig. 7 and 9, the seventh shell appliance 9 differs from the third shell appliance 7 in that: the edge of the guide plate 91 of the seventh shell-shaped dental appliance, which is used for connecting the distal ends of the two cuspids, is of a structure which is consistent with the direction of the dental arch, that is, the guide plate 91 of the seventh shell-shaped dental appliance has a U-shaped structure similar to the dental arch in overall shape. If the occlusion force of the patient is large, the convex part of the guide plate 91 of the seventh shell-shaped tooth appliance is easy to bend towards the tongue of the patient, and can be matched with the front end of the tongue when the upper jaw and the lower jaw are occluded, so that the wearing comfort is high. Compared with the guide plate 91 of the seventh shell-shaped dental appliance, the connecting line of the guide plate 71 of the third shell-shaped dental appliance connecting the distal ends of the two cuspids is a straight line or an approximately straight line structure, that is, the guide plate 71 of the third shell-shaped dental appliance has a larger area covering the palate than the guide plate 91 of the seventh shell-shaped dental appliance, so that the guide plate 71 of the third shell-shaped dental appliance has good strength and is not easily deformed even if subjected to a large biting force.
Although the embodiments of the present invention have been described in detail hereinabove, it is apparent to those skilled in the art that various modifications and variations can be made to these embodiments. However, it is to be understood that such modifications and variations are within the scope and spirit of the present invention as set forth in the appended claims. Moreover, the invention as described herein is capable of other embodiments and of being practiced or of being carried out in various ways.
