Definitions

  • TITLE UNIVERSAL ACRYLIC TEETH HOLDING DEVICE FOR TRIMMING
  • the invention relates to dental appliances. More particularly, the present invention relates to an universal acrylic artificial teeth trimming device and method of trimming thereof.
  • Dentures are made for patients who have lost their natural teeth. Dentures, also known as false teeth set, are prosthetic devices constructed to replace missing teeth. The processes utilises artificial acrylic teeth which are available in various sizes, colour and forms commercially. Most artificial teeth are made from high quality acrylic resins, which make them stronger and more attractive. The acrylic resins are relatively wear-resistant, and teeth made from these materials are expected to have long life.
  • the main object of the present invention is to fabricate a novel universal acrylic artificial teeth trimming device.
  • Another object of the present invention is to fabricate a versatileteeth trimming device that can securely hold and readily adapts to the tooth contour while trimming thereby helping in stabilizing the acrylic teeth of any brand, size and form.
  • Yet another object of the present invention is to fabricate a trimmer device which is devoid of problems such as difficulty in holding the teeth with small size, slippage of the teeth and damage to the fingers while trimming etc.
  • Yet another object of the present invention is to develop a method of trimming acrylic artificial teeth utilizing the fabricated trimming device.
  • Yet another object of the present invention is to fabricate a trimmer device that can trim allkinds of teeth including incisors, canines, premolars and molars made of acrylic.
  • Further object of the present invention is to utilize the fabricated universal acrylic artificial teeth trimming device for manufacturing dentures.

  • Figure 2 depicts the device of present invention showing modelling wax filled in the wax wells
  • Figure 3 depicts the device of present invention showing securing clip in place
  • Figure 4 depicts the device of present invention showing attachment of any tooth size and form to the device

  • Figure 7 depicts conventional free hand trimming SUMMARY OF THE INVENTION:
  • the present invention shall disclose a universal acrylic artificial teeth trimming device and method of trimming thereof.
  • the device comprises of a base, a plurality of wells, modelling wax and securing clips.
  • the base has a plurality of wells and the wells are filled with modelling wax up to the brim for placing the teeth to be trimmed.
  • the securing clips are removably mounted to the baseto stabilize the tooth placed in the modelling wax while trimming.
  • the invention is characterized in the modelling wax and securing clips.
  • the modelling wax readily adapts to the shape of the toothcontourand helps in stabilising the tooth during trimming.
  • the securing clips retain the acrylic tooth in the locked positionduring trimming without the problem of slippage of the teeth.
  • the present invention shall disclose a universal acrylic artificial teeth trimming device and method of trimming thereof.
  • the present device holds the tooth securely while trimming. Also the device is versatile since any size and form of teeth can be easily trimmed using the device.
  • the device is novel as it could be used to trim any size or form of acrylic artificial teeth. This will greatly help the dentist and the dental technician in fabricating dentures.
  • the device consists of a metal block (850 mm X 20 mm X 6 mm) with 2 wax wells. Each well has a dimension of 20 mm X 12 mmX 3 mm.
  • Figure - 1 Modelling wax is filled inside the wax wells up to the brim. Two wells are available for convenience and ease of use. Once modelling wax from one well loses it tackiness, the second well can be used for trimming without having to worry about replacing the modelling wax.
  • Figure - 2 A securing clip is available to stabilise the tooth once it is mounted to the device for trimming.
  • the securing clip is also easily replaceable in case of wear. The modelling wax and the securing clip retain the acrylic tooth while trimming.
  • the modelling wax readily adapts to the shape of the tooth being trimmed and so tooth of any size and shape can be mounted on to the device and trimmed.
  • Figure - 4 The method of trimming the teeth using the device of the present invention is as follows.
  • the tooth to be trimmed is adapted to the modelling wax and secured with the clip. Once the tooth to be trimmed is firmly secured to the device, it can be easily trimmed with a micro motor and a bur.
  • Figure -5 The direction of rotation of the spinning bur has to be adjusted to prevent slipping of the tooth while trimming.
  • the figure 6 shows the untrimmed and trimmed teeth.
  • Removable complete and partial dentures are made using artificial acrylic teeth which are readily available in different sizes and shapes in the market.
  • these stock acrylic teeth have to be custom trimmed for individual patient use.
  • these stock teeth are trimmed freehand with a micromotor and a bur ( Figure - 7).
  • freehand trimming of artificial acrylic teeth poses difficulty in holding teeth which are small in size. Very often the tooth that is trimmed slips from the finger making trimming a frustrating experience. Also the rotating bur burns the skin of the finger on accidental contact.
  • the device of the present invention avoids all the above mentioned problems and is very useful in efficient trimming of acrylic teeth.
  • the device is versatile in that any brand of acrylic artificial teeth can be used with the device. Teeth with different sizes and forms can be used with the device. All teeth including incisors, canines, premolars and molars can be trimmed using the present device and so device has a universal application.
  • the device of the present invention is easy to use since the tooth to be trimmed can be easily locked in position on the device and trimmed.
  • the modelling wax in the wax well readily adapts to the tooth contour and helps in stabilising the tooth during trimming.
  • the device eliminates the need to touch the tooth during trimming thereby eradicating the risk of damage to the fingers.
  • the present invention shall disclose a universal acrylic artificial teeth trimming device for securely holding the acrylic teeth of any brand, Size and form while trimming thereby overcoming the problems of difficulty in holding the teeth with small size, slippage of the teeth while trimming and the like.
  • the device of the present invention comprises of a base, a plurality of wells, modelling wax and securing clips.
  • the base of predetermined dimensions has plurality of wells of predetermined dimensions, disposed at predetermined position on the base.
  • the wax wells are filled with modelling wax up to the brim of the wells for placing the teeth to be trimmed.

Abstract

La présente invention concerne un dispositif de maintien de dents artificielles acryliques universelles et un procédé d'ajustage de celui-ci. Le dispositif comprend une base, une pluralité de puits, une cire de modélisation et des clips de fixation. La base comporte une pluralité de puits et les puits sont remplis de cire de modélisation jusqu'au bord afin de placer les dents à ajuster. Les clips de fixation sont montés de manière amovible sur la base pour stabiliser la dent placée dans la cire de modélisation pendant l'ajustage. L'invention est caractérisée par la cire de modélisation et les clips de fixation. La cire de modélisation s'adapte facilement à la forme du contour de la dent et contribue à stabiliser la dent pendant l'ajustage. Les clips de fixation retiennent la dent acrylique en position verrouillée pendant l'ajustage sans le problème du glissement des dents.
