LIP POSITIONING DEVICE AND METHODS OF ITS USE

Abstract

A lip positioner shows the surgeon where the upper lip is to be repositioned. It includes a mouthpiece and a platform extending to support the upper lip. It may be fabricated from poured stone in dental casts. The material sits on the upper teeth and has a forward facing platform sitting under the upper lip to lift up the lip to its new desired position during and after surgery. It can be used to show the proposed position of the upper lip preliminary to performing plastic surgery or hold the upper lip in a desired position while sleeping or working to retain the upper lip in a desired orientation or to hold the lip in the desired position during healing surgery to minimize the gravitational pull on the lip which will also minimize scarring of the incision area. The method of making and using the lip positioner is also disclosed.

SPECIFIC DESCRIPTION OF THE PREFERRED EMBODIMENT

[0035] Reference is first made to FIG. 1 which shows the inventive lip positioner generally designated by the reference numeral 10. The lip positioner 10 includes a mouthpiece portion 11 and a forward facing platform or shelf 13.

[0036] The mouthpiece portion 11 includes a recess including a plurality of recesses or pockets 15, 17, 19, 20, 21, 23, 25, 27, 29, 31, 32, 33, 35 and 37 which are provided to receive the upper teeth of the wearer. These recesses 15-37 are custom molded to the upper teeth of the wearer to ensure a snug and comfortable fit.

[0037] The platform or shelf 13 has an upper surface 14 which is at an elevation with respect to the upper teeth of the user to underlie the upper lip of the user and elevate the upper lip to a desired elevation. This is seen, for example, in FIG. 8 which shows the user/wearer 1 with the upper lip 2 and the platform or shelf 13 shown protruding outside the mouth with its upper surface 14 underlying the upper lip 2 and supporting it at a desired elevation.

[0038] FIG. 2 shows a top view of the inventive lip positioner 10 which shows in more detail the recesses 15, 17, 19, 20, 21, 23, 25, 27, 29, 31, 32, 33, 35 and 37 as well as the top surface 14 of the platform or shelf 13.

[0039] With reference to FIG. 3, the underside of the lip positioner 10 is shown and shows the bottom surface 16 of the platform or shelf 13 and the underside 18 of the mouthpiece portion 11. As seen in FIG. 3, there are no recesses in the underside 18 of the mouthpiece 11 to receive the tops of the bottom row of teeth. However, if desired, such recesses can be provided. FIGS. 2 and 3 show that the platform or shelf 13 has a forward surface 24 that is arcuate.

[0040] With reference to FIGS. 4 and 5, it is seen that the elevation of the top surface 14 of the shelf 13 is the same as or coplanar with the upper edge of the mouthpiece 11. Similarly, it is seen that the bottom surface 16 of the shelf 13 is at the same elevation as or co-planar with the bottom surface 18 of the mouthpiece 11. The general elevation of the top surface of the mouthpiece 11 is generally designated by the reference numeral 22 in FIGS. 4 and 5. This general elevation is set so that the upper lip of the user is placed at the desired elevation. The relationships between the elevation of the top surface 14 of the shelf 13 and the upper edge of the mouthpiece may be varied, as required, on a case by case basis based upon the physical characteristics of the patient and the desired results.

[0041] FIG. 6 clearly shows from a front view the platform or shelf 13 with its top and bottom surfaces 14 and 16 which are at the uppermost and lowermost elevations respectively of the lip positioner 10.

[0042] FIGS. 9 and 10 show cross-sectional views taken along the lines shown in FIG. 2 and further illustrate the dimensions and relationships between the shelf 13, the mouthpiece 11, and the overall structure of the lip positioner 10. FIG. 10 shows a cavity that is identified by the reference numerals 25, 27 which shows how the front teeth are received within a recess as also shown in FIGS. 1 and 2.

[0043] As explained above, the inventive lip positioner may be made in any suitable manner by using soft plastics molded in situ within the mouth, using 3-D modeling, using traditional dental lab methods of poured stone in dental casts using thin thermoplastic omnivac material, room temperature vulcanize, or any other suitable method or means.

[0044] As explained above, the inventive lip positioner can be used in several ways. First, it can be used without a surgical procedure having been done or contemplated as a retainer placed in the mouth supported over the upper teeth and positioning the upper lip in a desired elevation and orientation. Secondly, it may be employed in contemplation of surgery to inform the plastic surgeon and aesthetic dentist of a preferred elevation and orientation of the upper lip. Third, the inventive lip positioner may be employed after plastic surgery has taken place to elevate the upper lip to maintain the upper lip in the elevated position through the healing process.

[0045] With reference to FIG. 11, a flowchart is provided which explains the inventive method of using the inventive lip positioner.

[0046] With reference to FIG. 11, as a first step, records are gathered concerning the patient for whom the lip positioner will be provided including taking photos of their face and smile and upper and lower scans of their jaws or, alternatively, alginate impressions either in the medical office or using a home kit provided to the patient. Next, an aesthetic evaluation form typically used in dental practices is completed to obtain the necessary aesthetic and technical information needed to practice the method.

[0047] A first section of the aesthetic evaluation form requests that the patient respond to questions such as what changes they would like to see in their smile, what is their preferred visual image of their teeth, whether straight, white and perfect; clean, healthy and natural; or white and natural. This section also requests information concerning the history of any aesthetic changes that have occurred in the patient's teeth over their lifetime. Finally, this section of the form requests that they provide previous records concerning what their smile looks like.

[0048] A second section of the aesthetic evaluation form requests a facial analysis including obtaining measurements of the full smile, of the lips at rest, of the lip dimensions including upper lip length, upper lip height, and lower lip height as well as information concerning a profile view, in other words, viewing the lips from each side of the face.

[0049] A third section of the aesthetic evaluation form requests information described as a dento-facial analysis of vertical and horizontal components. A first subsection requests information concerning the upper smile line, whether it is average, high or low; a second subsection requests information concerning incisal edges to lower lip, whether they are convexly curved, straight or reversed; a third subsection requests information concerning the lower lip position with respect to the teeth as to whether they are touching, not touching or slightly covered; a fourth subsection requests information as to the number of upper teeth displayed when a full smile is exhibited; a fifth subsection requests information concerning the midline location from the central incisors to the philtrum; a sixth subsection requests information as to whether the midline of the smile is skewing to the left or right; a seventh subsection requests information concerning possible bilateral negative space; and an eighth subsection requests information concerning phonetics.

[0050] A fourth section of the aesthetic evaluation form concerns dental analysis. This includes information concerning the shades (colors) of the teeth, width to height ratio of the central incisors, proportions with respect to central/lateral/canine teeth, an occlusal analysis which determines whether there is complete occlusion, determines incisive position, and determines left and right working, and additionally, micro-aesthetic elements concerning incisal edge position, soft tissue symmetry, zenith positions, axial inclination, embrasures and contacts, and texture and edge contours. A further subsection diagnoses wax-up information.

[0051] With all of the information set forth above completed, it may be evaluated so that the aesthetic dentist and plastic surgeon have sufficient information to determine how to proceed with plastic surgery if necessary and/or desired and preparation and manufacture of the lip positioner.

[0052] The next step in the inventive method is to utilize digital design software, such as NEMOTEC software or an alternative to it that is known to those of ordinary skill in the art to create an ideal smile image using the information provided in the aesthetic evaluation form to enhance facial aesthetics. An electronic file is created and saved as an .stl file. Alternatively, dental ceramists may create a diagnostic wax up manually. The digital design software shows the image in two dimensions. So once the two dimensional image is created, additional software known to those of ordinary skill in the art is employed to convert the two dimensional smile image into a three dimensional design, also using the technical and aesthetic information provided in the aesthetic evaluation form. This conversion may employ Sirona InLab Splint software which creates a splint file which is imported into a Meshmixer where the file is distorted to create the platform.

[0053] Next, 3D printing technology known to those of ordinary skill in the art, such as that which employs CAM software, is employed to take all of the data from the 3D design created using the above-mentioned software which has been saved as an .stl file and create a template in order to transfer the design into the patient's mouth. This is the same template created for the diagnostic wax up. Next, the patient tries on the template to see if it properly fits and, importantly, elevates the upper lip to the elevation that will be desired when the entire process has been completed.

[0054] With the template located in the patient's mouth, a three dimensional facial picture is taken with a 3D camera.

[0055] The next step in the inventive method is to employ 3D modeling software to design the lip elevation necessary in accordance with the facial aesthetics desired by the patient with consultation with their dentist and plastic surgeon. Once this step is completed, 3D design software, known to those of ordinary skill in the art, is utilized to create the lip positioner that fits over the upper teeth and includes a platform or shelf protruding forwardly that moves the upper lip upward a desired distance such as 2 mm to 5 mm or even greater if necessary.

[0056] With the lip positioner being created, it can be employed in any one of the manners described hereinabove, including after plastic surgery to maintain the upper lip in an elevated position through the healing process, or in contemplation of such surgery to allow the plastic surgeon and aesthetic dentist to view where the upper lip will be located after surgery or, even without any surgery contemplated to be used as a retainer to position the upper lip in a desired elevation and orientation to deter aging processes which would eventually lower the lip.

[0057] Through use of the inventive lip positioner and the inventive method of its use, in its various forms and processes, the aesthetic appearance of the face of the user (patient) can be preserved during the aging process without surgery or restored to its previous form or to a more aesthetically pleasing form through use of the lip positioner in conjunction with surgical procedures.

[0058] As such, an invention has been disclosed in terms of a preferred embodiment thereof which fulfills each and every one of the objects of the invention as set forth hereinabove, and provides a new and improved lip positioning device and methods of its use of great novelty and utility.

[0059] Of course, various changes, modifications and alterations in the teachings of the present invention may be contemplated by those skilled in the art without departing from the intended spirit and scope thereof.

[0060] As such, it is intended that the present invention only be limited by the terms of the appended claims.
