The invention relates to medicine, in particular to prosthetic dentistry, and can be used to determine the speech adaptation to different designs of prostheses in orthopedic treatment of patients with partial and complete loss of teeth.
From the existing prior art discloses a method for determining adaptation to orthopedic dental structures, consisting, including self-evaluation of the patient's own speech .
In the known method, the patient is asked to evaluate their own speech immediately after implantation of the prosthesis, on the second, seventh, tenth, fourteenth, twenty-first, twenty-eighth and thirty-fifth day after applying. In addition to other indicators of adaptation, the patient must choose one of three options: it is not broken, a slight change in diction, speech impaired, illegible.
The disadvantages of this method include: subjectivity - the pronunciation of the patient, the same phrase can be perceived differently, as the organ of hearing person is imperfect and not always able to distinguish normal pronunciation from the pathological.
The closest technical solution (prototype) is a method of monitoring the restoration of speech in patients with removable prostheses . The known method of monitoring the restoration of speech in Bolnisi removable dentures includes pronunciation of tests at different times after the imposition of dentures in the mandible and evaluation of speech intelligibility. As a test, the patient pronounces each letter of the alphabet at the same time are recording to a digital medium the sound of the letters and graphics showing the amplitude and frequency of oscillations, and control the restoration of speech is carried out by comparing records between themselves on the stages of the research, as well as with the standard audio and graphical records of spoken letters.
The disadvantages of the prototype should include:
- a large number spoken by the patient, whilst in the prosthetics suffers the pronunciation of consonants hissing sounds ("C", "C", etc.), which lengthens the time of evaluation;
the timing of monitoring for too long (a week), as adaptation to dentures is much faster ;
- there is no specific formula for determining full adaptation or the degree of proximity to the benchmark;
- the value is taken as the standard for each sound specifically, it is determined subjectively;
- applies only to removable dentures.
The problem to be solved by the claimed invention is the objectification of the evaluation function, speech formation after implantation of the teeth and the timing of speech adaptation to various kinds of dental prostheses, by comparing the outcomes of patients with benchmark, obtained experimentally, identifying W�according to the timing of speech adaptation to various factors by using a specific formula.
The technical result of this method is: the ability to objectively assess the quality of dental intervention/correction in this aspect of speech production, in three phonemes "C", "C" and "f".
The problem is solved due to the fact that in the method of determining the recovery of phonetic features after prosthetics has the following differences: what is new is that were obtained experimentally benchmarks speech frequencies in three phonemes - "C", "C" and "f". Proposed standard for all patients phrases. The entry standard phrases is not only immediately after implantation of the prosthesis, but also to dental treatment, then every other day after implantation of the prosthesis, three days, five days and so on until reaching the norm. Thus, assess the quality of dentures made from the perspective of phonetics and speech speed adaptation. Depending on personal characteristics, the timing of monitoring may change.
The essence of the proposed method is as follows. In a closed space, in the absence of extraneous noise on a personal computer using a standard microphone recording of certain phrases containing the phoneme "C", "C" and "f" in a patient with tooth loss, dental �of mestella. Then, in the computer program Sony Sound Forge pro v.10.0 c analyze recorded, and peaks sonogram determine the frequency of the sound for the patient. This indicator - sound frequency pathology - CSP. The figure is fixed. The next stage is the entry of the same phrases in the same conditions and the same patient, immediately after orthopedic treatment - this will be the frequency of the sound after treatment - CSL. Next, calculate the magnitude of the differences (BP) between the frequency of a sound is OK (CSN) (indicator was found empirically for a group of persons not suffering from speech disorders, not having any of the structures in the oral cavity 3 phonemes) and CSP(BP-1) and CSL(BP-2). Calculate the ratio, which would be a phonetic indicator of rehabilitation and will provide an objective assessment phonetically successful or unsuccessful Vice versa prosthetics. The General formula is as follows:
FPR - phonetic indicator of rehabilitation,
BP-1 - magnitude differences 1,
BP-2 - value differences 2,
CSN - frequency sound normal for selected phonemes,
CSP - frequency sound of pathology,
CSL - frequency sound after treatment.
The invention makes it possible to install the provided quality dental prosthetics or correction of speech in speech therapy for the objective indicator, the frequency of sound �isolating phonemes. The norm for three different phonemes, and only slightly depends on the sex of the patient.
The ability of embodiments of the invention are shown by the following example.
Example 1. Patient B., aged 56, has complained of the loss of the front teeth of the upper jaw. Was diagnosed with Partial loss of teeth of the upper jaw 1 class at Kennedy. A plan of treatment. Before treatment was carried out recording phrases in three phonemes and analyzed using the sonogram - Fig. 1.
The peaks of the sonogram (marked by arrows) correspond to the moments of the pronunciation of the sound "C" in the phrase "how much is a haystack". The frequency of the sound is from 5.5 to 6.7 kHz, which is the pathology and perceived by the ear, as the sound "sh". To calculate the average is taken from 5.5 to 6.7 (6,1 kHz).
After the implementation of the treatment plan, the patient was asked to utter the same phrases, and was carried out the same analysis - Fig. 2.
The peaks of the sonogram (marked by arrows) correspond to the moments of the pronunciation of the sound "C" in the phrase "how much is a haystack". Sound frequency is 12.5-12.7 kHz, which corresponds to the norm (for a given phoneme from 12.7 and more), but the patient is not satisfied with the pronunciation.
The next step was to record speech samples in three days after implantation of the prosthesis. According to the patient's speech production recovered, objective assessment of sonogram� confirmed it - Fig. 3
The peaks of the sonogram (marked by arrows) correspond to the moments of the pronunciation of the sound "C" in the phrase "how much is a haystack". Sound frequency is 15.5 and 17.7 kHz, which corresponds to the norm, the patient is satisfied with the pronunciation. To calculate also use the arithmetic mean. In this situation it is equal to 16.6 kHz.
In this example, there is no record of the sonogram in a week, as and for three days had passed full speech adaptation and later the sonogram unchanged.
Substituting values in the formula methods
FPR=|1,7|>|1| that shows the successful recovery of language functions in this patient after implantation of three days later.

SUBSTANCE: invention refers to apparatuses determining a degree of an individual's scoliosis. The apparatus comprises a casing integrating a grid and a movable platform provided with step motors and comprising a photographic camera and a projector apparatus. The casing is openable and closable and can accommodate a patient. The step motors, projector apparatus and photographic camera are regulated by a controller receiving signals via a modem communication line from the computer.
EFFECT: using the invention provides the higher accuracy and rate of determining a degree of scoliosis, as well as a mobility of the examination by using the shadow moire method.
SUBSTANCE: examined individual is tested prior to and after a surgical management, on a stabilographic platform; stabilographic values are read, recorded, processed and analysed using computer-assisted techniques. Frontal and sagittal coordinates obtained prior to and after the surgical management are used to determine parametric and visual changes in shapes: a three-dimensional histogram of the occurrence frequency of certain length and rate intervals; two-dimensional histogram of the occurrence frequency of a certain length interval, the occurrence frequency of certain rates for all intervals and for each length separately; a diagram of an interval rate and length dispersion, a departure of which from normal values characterises a degree of motor disturbances; change values and directions describing improving or deteriorating the patient's bone-articular, muscular and nervous conditions; that is ensured by drawing the above histograms and diagrams to determine their shape, statistical parameters and structural characteristics. The results prior to and after the surgical management are compared. The variations of the size and positions of the value ranges, the change directions, as well as the visual changes of histogram and diagram shapes are stated to describe the responses to the surgical management. The nervous changes are described by shape variations of the three-dimensional histogram surface related to the interval lengths. Reducing the range of intervals testifies to functional insufficiency of the nervous system in general, while the absence of the intervals of a certain length, or a disturbed bell-shaped shape of the histograms of the rates therefor testifies to the absence of closed reflex rings with respective periods of cycles or their pathological reconstruction. The muscular changes are described by the variations of rate dispersion ranges for all intervals, and for specific discrete lengths; reducing the ranges for all intervals in relation to the norm testifies to the muscular deficiency. The bone-articular changes are described by reducing or increasing an asymmetry of the three-dimensional histogram shape in general or displacing the middle rate variation ranges from a zero value for the certain length intervals; the asymmetry testifies to a bone-articular pathology.
EFFECT: method enables the fast and objective assessment of the consequences of the surgical management for a specific patient from the point of view of motor disturbance correction in general, as well as variations of the bone-articular, muscular and nervous system functioning.
