A method for predicting the timing of eruption of impacted teeth
(57) Abstract:The invention relates to medicine, namely to the dentist, and can be used to predict the timing of the eruption of impacted teeth. Conduct a thermal imaging survey of this area, the calculation of the received images on the computer program and upon receipt of temperature data within 36,388-37,266oIn the examined area predict the timing of eruption of impacted tooth without treatment and preventive measures. In case of deviations from these data 1-2oWith one side or the other make the corrections in the process of eruption. The method allows to predict the timing of eruption of the tooth with regard to the influences of the temperature factor in the area impacted tooth. The invention relates to medicine, namely to the dentist, and can be used to predict the timing of the eruption of impacted teeth.Currently, monitoring of teething carry out clinical examination of the area impacted tooth and, in some cases, radiographically (HP of person. Orthodontics. Diagnosis, types of dental anomalies. - Moscow, 1999, S. 202-203).For the prototypes of the invention is method of clinical examination in the field of impacted tooth, i.e. the examination, which should start monitoring the process of eruption of the tooth.However, this method, as well as x-ray, does not take into account important factors, such as the temperature in the area of the eruption of the impacted tooth. Practically, it was found that the temperature in this region is increased, but no one has determined how far it shall be that the tooth has come through safely, and in any temperature limits in this area, you can predict the delay of eruption, in order to make timely adjustments in this process.Therefore, the aim of the invention was to develop a method for predicting the timing of eruption of the tooth with regard to the influences of the temperature factor in the area impacted tooth.The invention consists in that in the area of impacted tooth determine temperature using a thermal imager and processing the received data using special software, the result of which determine the specific digital data to those who The method is as follows.The patient is seated in front of the imager at a distance of 0.5 m from it. The room should be temperature 23,01,00oWith the air speed should not exceed 0.25 m/s, relative humidity should be in the range of 50-75%. The study was conducted in the morning hours. Prior studies do not allow the medication and physiotherapy. Research begins with a thorough oral hygiene, then a dental retractor expose the gingival area of the upper and lower jaws.The imager after pouring in liquid nitrogen lead in working condition and immediately begin the study. Get a thermogram, which is treated by a special computer program, determining the temperature interval in the control area and in the area impacted tooth. As a result of numerous studies and statistical processing, the following data: in the area of impacted tooth temperature ranges from 36,388 to 37,266oC. At this temperature the tooth is cut through without any adjustments. In cases other temperature values below or above decree is complaining of delayed eruption of the tooth 13. On the orthopantomogram jaw tooth 13 is defined. Conducted clinical examination of the area impacted tooth and advanced imaging.It was established that the temperature in the area of impacted tooth equal 35,725oC. the Patient received 10 sessions of laser therapy. After treatment is again carried out thermal temperature determination, which was equal to 36,922oC. the Teeth begin to erupt. There were no complications.Just surveyed stated by way of 16 patients. In all cases the dependence of the timing of the eruption from the temperature in the area impacted tooth, which confirmed the need for temperature control of the area impacted tooth as an adjunct to clinical examination.The method allows to predict the timing of eruption of the tooth and to choose treatment and preventive measures in case of deviation from the norms of the temperature field.The method is not complicated, is not economically roads and can be recommended in the dental practice. A method for predicting the timing of eruption of the impacted tooth, including clinical examination region impacted zig infrared images on the computer program and upon receipt of temperature data within 36,388-37,266 With in the target area, predict the timing of eruption of impacted tooth without treatment and preventive measures, and in case of deviations from these data on a 1-2C in either direction make the corrections in the process of eruption.
SUBSTANCE: method involves opening palatine suture to normal palate shape with slight width hypercorrection of superior dentoalveolar arch. Device having cap covering parietooccipital area, rubber braces, facial arch composed of intraoral arch and two lateral extraoral parts. Intraoral arch ends are fixed on the sixth maxillary teeth. The device is applied for acting with forth directed upwards and backwards towards the crown of head. A force is applied to the sixth maxillary teeth arranged symmetrically relative to the palatine suture. Force of 300 to 400 g is applied to each side of the maxilla for 12-14 h per day to reach occlusion normalization in sagittal and vertical plane.
EFFECT: accelerated treatment course; improved cosmetic results.

SUBSTANCE: method involves carrying out gingiva retraction, forming L-shaped notches on central incisors medial surface and cutting edges. L-shaped reinforcing members produced in advance in conformance with the notches are arranged in the notches filled with fluid composite. The reinforcing members are set 1-1.5 mm below incisor cutting edges level. Guided polymerization of vestibular, oral and cutting surfaces being over, diastem is eliminated by coating medial surface of incisors layer-by-layer with composite material selected for being applied to frontal teeth group. The central incisors are polished and cutting edge is adjusted to recreate anatomical shape.
EFFECT: enhanced effectiveness of treatment.
FIELD: medical engineering.
SUBSTANCE: device has partial removable palatine plate prosthesis bearing artificial temporary. The palatine plate has an anterior and two lateral segments connected to each other by means of screw in the anterior palatine fornix region allowing autonomous displacement. Cramp iron members are set on the fangs and on the boundary separating the anterior and lateral segments and on the second temporary molars. Shield for moving upper lip aside is placed in the area of dental arch defect along alveolar process with anterior segment. The shield forms slit between shield surface and gingiva. The shield is stretched to contact point of fang to the first permanent molar. Shield edge is made oval and congruent to transit fold contour.
EFFECT: cosmetically full-valued substitution of upper dental arch defect.
FIELD: medical engineering.
SUBSTANCE: device has removable maxillary plastic plate and mandibular one. The plates are separate and joined with flexible tie rod. To provide uniform load distribution, the maxillary plate is manufactured as supporting member. The supporting member has arch in frontal part that is congruently adjacent to vestibular surface of the frontal teeth. The arch is manufactured from wire and rigidly connected to basis. Premolars and molars have cramp iron members on frontal contact surface. The mandibular plate is manufactured as mandibular alveolar part base and internal surface of lower teeth. The plate is fastened to dental row with cramp iron members and has flexible tie rod hooks.

SUBSTANCE: method involves carrying out X-ray examination and determining longitudinal axis tilt of retained tooth and computer tomography. Maxillary computer tomography is carried out in three-dimensional Descartes coordinates with central occlusion being preliminarily fixed with individual silicon gumshield. The gumshield has 2-4 mm thick bilateral occlusion surface. Calculated free space value being found greater than thickness (vestibulo-oral size) of the retained tooth, positive prognosis for successful moving out is determined by building geometrical model, carrying out mathematical analysis of received data. The calculated free space value being found equal to retained tooth thickness, prognosis for difficult moving out is produced. The calculated free space value being found less than retained tooth thickness, unfavorable prognosis for moving out is produced.
EFFECT: high accuracy in predicting orthodontic correction results in three-dimensional space.
