说明书全文 | Not Applicable Not Applicable Not Applicable 1. Field of Invention This invention generally relates to extraoral orthodontic appliances, specifically to an improved cushion system for the forehead rest and the chin cup of the protraction face mask 2. Prior Art There are several types of extraoral appliances used in contemporary orthodonture. Protraction face mask therapy is most effective in patients who are 10 years of age or younger since they are still growing. These devices can be connected to brackets or other hardware on the patient's teeth, usually with elastic bands, they then apply pressure to the patient's forehead and chin. Several styles of the protraction face mask exist and each claims to provide greater compliance of usage due to its particular design and the flexibility of the forehead and chin segments. Among the relevant protraction face masks there are Multi Just™ Adjustable Face Mask sold by Orthodirect (2010 Orthodontic Reference Guide, p.65) and those sold by Great Lakes Orthodontics, (Catalogue pp 60-63,65) namely: Adaptable Class III Mask, Reverse-Pull Face Cribs, Hickham Headgear and Keles Face Mask. None of these fully address the issue of discomfort that arises from the pressure of the forehead rest and chin cup. These devices are manufactured with adhesive backed thin foam coverings for the forehead rest and chin cup to ease the irritation and discomfort that results from wearing the apparatus. This padding is quickly worn down and frequently falls off due to body heat and moisture from perspiration. The edges of the forehead rest and chin cup are hard and press into delicate skin leaving marks, especially when the patient is sleeping and leans on the appliance. U.S. Pat. No. 5,205,735 discloses a headgear pillow which is used successfully with orthodontic/facial orthopedic appliance U.S. Pat. No. 4,988,291 to protect the patient's cheekbones. This deals with similar issues of discomfort and pressure on the face from an orthodontic appliance but it does not address a forehead rest or a chin cup. There are other extraoral orthodontic devices such as the Reverse Pull Face Crib which is produced with adhesive backed foam pads, and the Adaptable Class III Mask designed by Henri Petit which is sold with a silopad®. The adhesive backed foam pads do not amply cover the edges of the forehead rest and chin cup. Also perspiration and saliva cause foam pads to become malodorous and causes their adhesive properties to deteriorate. The silopad® cushion is used in the same manner as the adhesive backed foam pads and can also be uncomfortable since its composite material encourages perspiration and does not allow air flow to the skin. Successful treatment with extraoral orthodontic devices is directly related to compliance with their usage. Since the vast majority of patients treated with these devices are young children, comfort is critical to the child's commitment to the treatment plan. In addition, the attractiveness of the materials used in making the comfort cushions will also enhance the patient compliance. In accordance with one embodiment a cushion system for use with extraoral orthodontic protraction facemasks comprises a pair of cloth cushions adapted to fit one on the forehead rest and one on chin cup of said appliance In the drawings, closely related parts have the same number but different alphabetic suffixes. 12 vertical bar of protraction face mask 13 horizontal bar of protraction face mask, attachment connecting elastic bands 14 forehead rest of protraction face mask 15 chin cup of protraction face mask 21 forehead cushion frontal view 22 forehead cushion interior view 23a forehead cushion right side attachment device 23b forehead cushion left side attachment device 31 chin cup cushion frontal view 32 chin cup cushion interior side 33a chin cup right side cushion attachment device 33b chin cup left side cushion attachment device One embodiment of the cushion comfort system is shown in In the preferred embodiment the cushions are made of 100% colorfast cotton cloth, but any soft non-allergenic and washable fabric may be used. The cushions are filled with hypoallergenic synthetic polyfiber fill, but any soft pillow fiber fill may be used, including but not limited to, shredded fabric remnants or cotton batting. The cushions are loosely filled to about ¾″ thickness. Both cushions have a front side (21, 31 ( The manner of using the cushion comfort system requires attaching the cushions to the forehead rest and the chin cup rest of the protraction face mask orthodontic device. The cushion comfort system will provide protection and comfort for the child's forehead and chin while they wear their protraction face mask orthodontic device. The inside of the forehead cushion (22 ( The front of the forehead cushion (21 ( The front of the chin cup cushion (31 ( The cushions are removed in the same manner in which they were attached; one side at a time. I presently contemplate that the cushions are made of entirely washable materials, and they may be easily removed and cleaned when necessary. There are various possibilities with regard to the shapes of the comfort cushion system. Additionally, there are various possibilities with regard to the method of attachment of the cushion comfort system. Elastic ribbons are simple to use, however, cloth straps, and adhesive backed hook and loop closures could also be used successfully. The shape of the extraoral face mask appliance is also determinative of the placement of the attachment devices. However, adjustments may be easily made by one skilled in the art to accommodate varieties in shape and size. Thus the reader will see that the various embodiments of the cushion comfort system can be used to make the wearing of protraction face mask appliances comfortable and inviting, and consequently improve patient compliance and improve medical results. The protraction face mask appliance is almost exclusively used in treating young children and its appearance can be intimidating for young children. Use of colorful and attractive printed fabrics for the cushion system lowers the level of anxiety in the patients. Additionally, the marked increase in comfort which results from a soft cushion protecting the tender skin on a child's forehead and chin will also improve their compliance with and the successful use of the protraction facemask appliance. While the above description contains many specificities, these should not be construed as limitations on the scope of any embodiment, but as exemplifications of the presently preferred embodiments thereof. Many other ramifications and variations are possible within these various embodiments. For example: the shapes of the cushions; the color, pattern and composition of the fabrics used in the manufacture of the cushions; the materials used in stuffing the cushions and the methods of attachment. For some types of protraction face masks only one of the two cushions may be necessary. Thus, the scope of the invention should be determined by the appended claims and their legal equivalents, and not by the examples given. |
