  • the lost tooth due to extraction for treatment or for any other reasons, result in spaces causing teeth to incline.
  • loss of molars such as true molars or false molars cause nearby teeth to incline towards the lost area and result in spaces between the inclining teeth and the adjacent teeth, and they brings the following problems.

  • the space (30) between the first tooth (10a) and the second tooth (10b) forms, and the above two teeth become inclined toward the space. That is, the crowns (11) of the first tooth (10a) and the crown (11) of the second tooth (10b) become closer, and the aperture (40) between the first tooth (10a) or the second tooth (10b) and the adjacent tooth (10c) occurs.

  • a coil spring (140) having elastic pressure towards the first (10a) and the second (10b) tooth is inserted, which is fixed with tubes (120a, 120b) . Therefore, the inclined first (10a) and second (10b) teeth are elastically pushed in the opposite direction, resulting in correction of the teeth.
  • This method compared to the above screw retained prosthesis method, maintains steady and consistent pressure to the teeth without any patient's operation, reduces the encumbrance of the patient.
  • the tubes (10a, 120b) are fixed on the lip side and the tongue side of the teeth (10a, 10b), and there still exist limitation on the correction since the elasticity is sided on either end. Also, the tubes (120a, 120b) , bracket (121), arch wire (130) and the coil spring(40) are widely spread over the oral cavity and expose themselves, therefore they still give the discomfort and trouble in aesthetic aspect, similar to the screw retained prosthesis.
  • Figure 2 and Figure 3 illustrate other example of the traditional orthodontics .
  • the teeth (10a, 10b) are pressed away from the area of the lost tooth (30) from the lip side and the tongue side of the teeth, more uniform correctional pressure is imposed and more accurate correction is possible, the prosthesis is limited to the area of the lost tooth (30) , and the discomfort is reduced.
  • the orthodontics in this example changes the point of elastic pressure by the coil spring (24) on to the first (10a) and the second (10b) teeth depending on the gradient of the teeth, therefore, cannot apply accurate correctional pressure. For this reason, it requires replacement of the band (210) and tubes (220) and cost arises as time goes by.
  • This invention is purposed on solving the existing problems of the orthodontics. It tries to minimize the discomfort and the inconvenience of the patient, to solve the aesthetic problem, to reduce the encumbrance and the cost during the treatment, and to allow any dentists without prior experience to practice the treatment.
  • any dentist without professional knowledge can practice such treatment using the prosthesis, and it is effective in terms of practice duration, treatment duration, and the cost.
  • the dentition orthodontic device (300) is completely inserted on the area of the lost tooth (30) and the spring (330) is not exposed, it can satisfy the patient's discomfort, inconvenience, and aesthetic desire.
  • the problem of the reduced space of the area of the lost tooth (30) due to the long time negligence can be solved for inserting artificial tooth, and it can prevent food from getting in the spaces around and on the area of the lost tooth (30) .
