Abstract. There are frequently seen cases in life when a person's teeth are perfectly healthy in terms ofpathology, caries and other diseases, but not ideal from an aesthetic point of view. The color of teeth may not be sufficiently white, their shape is not smooth enough, and in general, the smile, despite the health of teeth, does not look "Hollywood". Although social status and position of the person sometimes just calls for it. Fantastic opportunities of aesthetic dentistry, aimed at improvement of teeth external defects and maximum use of existing advantages comes to the rescue.
Keywords: Lumineers, modern methods, restorative dentistry, minimally invasive intervention, beauty, smile.
Relevance of the topic. Lumineers - it is the ultra-thin ceramic plates, which are put directly on the surface of the tooth. Main advantage of Lumineers over composite and ceramic veneers is -before installing them there is not necessity of grinding down tooth enamel. This technology has two advantages. At first, since the upper layers of enamel are not removed, therefore there is not increase of sensitivity of teeth. At second, the patient may at any time withdraw such lumineers - before and after wearing the teeth will look the same.

Next generation Cerinate - is a highly aesthetic product, pressed Feld spathic porcelain reinforced with leucite Nano crystals. Due to its superior strength of 216 MPa. Lumineers can be made as thin (0.2 - 0.5 mm) as a contact lens, that allows them to be installed without removal of enamel and dentin. Lumineers are individually made for each patient and bonded on outer surface of the tooth.

Algorithm of actions was made while placing lumineers. While assisting the dentist Karakots D. M. placing lumineers procedure was done.
For the first visit we do oral examination and recommend dental brace to be employed, for teeth transformation. Diagnosis: Discolored teeth .
Algorithm of actions:
1. Taking an impression using PRECISION material (first impression material, DENMAT).
2. Filling out the form to be sent: selection of desired smile, that includes choice of shape and color of future teeth, transmissivity (high, medium, low)
Picture «Before», for technicians in the laboratory.
Picture of desired smile.
3. Making a diagnostic model. Sending the mold and all attached documents to Italy or Switzerland. Receipt of finished material in special boxes after 3-4 weeks. Technicians develop the design of the final dentition model in computer laboratories in order to fit all the requirements of a dentist.
For the second visit:
1. Placing of soft lip retractor OptraGate
2. Isolation of soft tissue with a liquid dam Paint-On Dental Dam.

Fixation of prepared lumineers on TRY-IN PASTE, TRY-IN PASTE - is not hardening paste on the basis of synthetic resin. It allows to choose the shade of Ultra-Bond Plus (or Block-Out) during cementing porcelain veneers / crowns procedure.
3. Conditioning of enamel, ETCH-N-SEAL - phosphoric acid for etching enamel and dentin, combines 25% phosphoric acid with 0.5% aluminum oxalate.
4. Application of bond-system. ADHESIVE Tenure A and B (multifunctional system of chemical curing) or Tenure S (single-composition, light curing). Fixing the material on composite adhesive-cement BLOCK OUT by ULTRA BOND PLUS - multifunctional dual curing cementing material, designed specifically for bonding porcelain restorations. Formula was developed on base of successful advanced polymer-cement technology, and also has a part of the masking material that is capable of perfectly masking the teeth stains.
5. Curing with SAPPHIRE PLUS PLASMA ARC light.
6. Final polishing using finishing burs.
The results obtained. Result «Before» placing lumineers and «After»
Conclusion. Using Cerinate porcelain LUMINEERS, we came to the conclusion that they have the following properties:
1. They have the most natural and aesthetic result and color.
2. Convenient to use
3. High strength.
4. Psycho-emotional condition of the patient was not disturbed

Спирография, ЭхоКГ и ЭКГ произведена у 58 (62,3%) детей с ГЛ в возрасте от 5 до 15 лет, обследованные дети были разделены на 2 группы.
В первую группу (41 ребенок) вошли дети с антенатальной ГЛ (РФ, ПФ, КФ, ВЛЭ). Длительность заболевания у этих детей составила более 4-х лет, течение отличалось частыми рецидивами, протекающими с явлениями выраженной интоксикации и дыхательной недостаточностью.
Во вторую группу (ГБ, 17 (18,2%) детей) вошли дети, у которых заболевание протекало благоприятнее, чем в 1 группе, хотя эти дети довольно часто болели простудными заболеваниями. Давность заболевания превышала 2 года, рецидивы были редкими (табл.1).
Из таблицы 1 видно, что наибольшие изменения функции внешнего дыхания были характерны для детей первой группы и в возрасте 11-15 лет: одышка, гипервентиляция легких, снижение ЖЕЛ, ТТ. Нужно отметить, что у детей обеих групп показатели функции внешнего дыхания, давая некоторую положительную динамику, оставались стойко измененными. В первой группе эти изменения были более выражены, чем во второй. Наряду с этим выявлена заметная разница (по сравнению с 1 -й группой) в показателях, отражающих состояние
