"Hollywood smile"
“Hollywood Smile” is a media ideal dating back to the beginning of 1900. The teeth were so rascal that people did not smile behind the photos. The only smiles seen were created in the published media as cartoons. The artists influenced the teeth as solid white areas with upper and lower teeth separated by a curved line following the lower lip. The curved line created the image of the front teeth, which is the longest, and each tooth gets an arrow to the very corners of the mouth.
Today, the “Hollywood smile” is an improved media ideal. The lips are filled with very white teeth that block the darkness in the back of the mouth. The cap edges of the upper teeth follow the line of the lower lip, which is a millimeter of contact. The two front teeth are most noticeable, with additional teeth appearing consistently smaller than the front teeth, to the corners of the mouth, creating a perspective. Ideally, each tooth looks sixteen smaller than the adjective tooth in front of it. There is a symmetry of color, shape and position of the tooth on the right on the left side of the midline.
Masculine smile has square teeth. Cutting the edges of the upper teeth occurs in a straight line. The female smile has rounded teeth. The edges of the upper teeth follow the lower lip line, creating more curvature.
Natural smile
Natural smiles are visible every day. The teeth fill the space between the lips and block the darkness in the back of the mouth. These are shades that blend with skin tones. Acidic edges of the upper teeth follow the line of the lower lip, but the two lateral incisors adjacent to the front teeth are shorter. Eyes look longer. The two front teeth are most noticeable, with additional teeth appearing consistently smaller than the front teeth, to the corners of the mouth, creating a perspective. Ideally, each tooth looks sixteen smaller than the adjective tooth in front of it. The symmetry of the color, shape and position of the tooth has the right side to the left side of the midline, but the change creates a natural look. The development and aging of teeth changes this relationship.
Natural smiles often rotate, bend, scream, or explode. There is wear on the outer and biting surfaces, gum recession and loss of roots, chips, cracks or cavities. Four front incisors of the same color, eyes darker, and bicuspids and molars slightly lighter. Each tooth has a large color rendition on the surface. The teeth have a reliably transparent enamel shell with yellow dentin beneath. As the enamel reduces and shows through the yellow dentin, the tooth looks more yellow, as it happens in the third tooth closest to the gums. Areas where the dentin is not behind the enamel, as occurs between the teeth and along the edge bite, look dark gray because the translucent enamel allows the darkness of the back of the mouth to appear.
The back of the mouth is a dark space because there is no light. Incorrect tooth position, tooth loss, abnormal teeth, and loss of tooth structure from injuries or cavities create spaces that show the darkness of the back of the mouth.
Aesthetics of Perception
Aesthetics perception recognizes that various smile patterns and teeth defects are used to create natural smiles, and that the patient's dentist's perception leads to a final smile design that suits a person. Determining the aesthetic values of the patient and the level of assessment is important for patient satisfaction. Without a proper assessment, the final smile design becomes the artistic interpretation of the dentist, which may or may not be acceptable to the patient. A dentist who does not understand the aesthetics of perception produces the same smile for each patient within the limits of physical or financial limitations. A perfect smile based on the “Golden Rule” of aesthetic dentistry may be ideal for a 20-year-old patient, but not ideal for an elderly patient. Table 1 lists the types of defects that need to be assessed to ensure patient satisfaction.
The goals of recovery should be balanced with the limitations of ideas and the limitations of treatment. Constraints of ideals include general practices (cultural, physical, and personal limitations), detailed examination, and visual perception. Treatment restrictions include patient and dentist restrictions. Limitations for patients include physical, psychological and financial limitations. The limits of the dentist include artistic, insightful and technical abilities (i.e. Material and laboratory limitations). "
Defects of teeth and smiles
Teeth defects that affect the aesthetics of a smile include color, shape, and position. Correction of unacceptable defects affects smiles. The inclusion of acceptable defects creates a natural smile. Aesthetics is an art, and therefore beauty is a personal preference, and determining patient preferences is crucial.
treatment
The goals of treatment should be realistic based on the constraints of the ideals and the limitations of the treatment. Perception Aesthetics is a concept that I published in the 1990 Esthetic Dentistry magazine. Perception Aesthetics considers all the factors that define realistic expectations for treatment purposes.
Aesthetic reconstruction
Aesthetic re-contouring is the process of selectively remodeling teeth to affect their shape, position, length, and contours. Young, female smiles are usually characterized by rounded edges. In a more manly smile or one characteristic of an older person, flat worn surfaces are more noticeable. Significant generalized changes are possible with the treatment of the front teeth visible on the patient’s face. Ideally, re-contouring is determined by enamel and gives the teeth the correct proportion. Significant changes are possible with the treatment of the front teeth that are visible on the patient’s face.
Teeth whitening
Bleaching relieves teeth by removing a speckled cough in microscopic holes inside the enamel. The active ingredient in most bleaching agents is carbamide peroxide, also known as urea peroxide; when water comes into contact with this white crystal, the release of hydrogen peroxide eases teeth. Bleaching is successful in at least 90 percent of patients, although this may not be an option for everyone. Consider teeth whitening if your teeth darken by age, coffee, tea or smoking. Teeth darkened by yellow, brown, or orange respond better to brightening. Other types of gray spots caused by fluorosis, smoking or tetracycline are alleviated, but the results are not so dramatic. Each case is different. As a rule, there is improvement with a few shades, as shown in the shade guide for the dentist. If you have very sensitive teeth or worn enamel teeth, your dentist can whiten your teeth whitening. Existing restorations, such as crowns and fillings, do not change color.
A dentist or hygienist will impress your teeth to make a whitening device for you. The device is custom made for your mouth. Along with the appliance, you will receive bleaching materials, and you will be given instructions on how to wear the appliance. Some whitening systems recommend whitening your teeth for one to four hours a day. Usually for this type of system it takes from three to six weeks. Other systems recommend night whitening during sleep. This type of system usually requires only 10-14 days.
Lightness should last from one to five years, depending on your personal habits, such as smoking and drinking coffee and tea. At this stage you can choose a touch. This procedure may not be so expensive because you can probably use the same device.
The retreat time is also much shorter than the initial processing time. Several studies over the past ten years have shown that whitening is safe and effective. The American Dental Association has provided a seal for approving certain products for teeth whitening. Some patients may experience mild gum irritation or tooth sensitivity, which will be eliminated when the treatment ends.
Composite Fillers - Front Teeth
Composite resin is a plastic tooth-colored mixture filled with glass. Composites are not only used to restore areas of decay, but are also used for cosmetic smile enhancements, changing the color of teeth or changing distorted teeth.
To associate the padding material with your tooth, you must first remove the decay, prepare the tooth, and then process the enamel and dentine. After conditioning, a thin resin is applied, which combines with the etched surface. The bond strength of these fills is incredible.
After preparation, the dentist places the composite in layers using light specifically designed to solidify each layer. When the process is completed, the dentist will form a composite to fit the tooth. The dentist then polishes the composite to prevent staining and early wear. Binding increases the power of these restorations far beyond just recently.
Composites are connected to the tooth to support the remaining structure of the tooth, which helps prevent breakage and isolate the tooth from excessive temperature changes. After taking the composite material, the patient may experience postoperative sensitivity. In addition, the shade of the composite may change slightly if the patient drinks tea, coffee, or other colorants. The dentist may place a clear plastic coating over the composite to prevent discoloration if the patient is particularly concerned about the color of the teeth.
Composites tend to wear out in large cavities, although they hold well in small cavities. After placing you can immediately chew. Light instantly hardens these fillers. Your teeth may experience some sensitivity to temperature for several days a week. If it does not disappear within this period of time, consult your dentist.
These light-cured composites are extremely cosmetic and are most often combined in one place. They are often called "binding." Studies have shown that composites last 7-10 years.
In the past, teeth were most often restored using silicate or acrylic restorations. Thanks to the achievements of modern dental materials and technologies, teeth can be restored with a more aesthetic and natural appearance. Various types of cosmetic fillers are currently available. The type used will depend on the location of the tooth and the amount of dental structure that needs to be repaired.
White Composites - Rear Teeth
Composite resin is a plastic tooth-colored mixture filled with glass. Previously, dental composites were chained to the front teeth, because they were not strong enough to withstand the pressure and wear caused by the back teeth.
After preparation, the dentist places the composite in layers using light specifically designed to solidify each layer. When the process is completed, the dentist will form a composite to fit the tooth. The dentist then polishes the composite to prevent staining and early wear. The dentist takes about 10-20 minutes longer to place the composite than the silver filling. The placement time depends on the size and location of the cavity, and the larger the size, the longer it will take.
The average cost of rear composites is about one and a half to two times the price of silver filling. Most dental insurance plans cover the cost of the composite up to the price of a silver filling, while the patient pays the difference. As composites continue to improve, insurance companies are more likely to increase the coverage of composites.
Aesthetics are one of the main advantages, since dentists can mix shades to create a color almost identical to the color of the actual tooth. Communication with the tooth to support the remaining structure of the tooth, which helps prevent breakage, minimize leakage and isolate the tooth from excessive temperature changes.
After taking the composite, the patient may experience postoperative sensitivity. In addition, the shade of the composite may change slightly if the patient drinks tea, coffee, or other colorants. Composites tend to wear out earlier than silver fillers in large cavities, although they also persist in small cavities. Studies have shown that composites last 7-10 years, which is comparable to silver fillers, with the exception of very large restorations, where silver fillers last longer than composites.
In the past, teeth were most often restored with the help of amalgam (silver) or gold restorations. Thanks to the achievements of modern dental materials and technologies, teeth can be restored with a more aesthetic and natural appearance. Various types of cosmetic fillers are currently available. The type used will depend on the location of the tooth and the amount of dental structure that needs to be repaired.
Another type of “white fillings” is called composite or porcelain inlays and online. These fillings are usually placed in the back teeth, when aesthetics are of particular concern. To increase their strength and durability, they are made in the laboratory and then fixed in the office. This is a two-visit procedure, not a single visit, necessary to accommodate a direct composite filling. However, when it comes to durability and cosmetics, the extra time and expenses are worth it! I hope, now you will understand a little more about white fillings.
Porcelain Veneers
Porcelain veneers are thin shells of ceramic material that are attached to the front of the teeth. They may be the ideal choice for improving the appearance of the front teeth. Porcelain veneers are placed to mask colors, close spaces, brighten teeth, straighten teeth and restore damaged tooth structure. Highly resistant to permanent staining from coffee, tea, or even cigarette smoking, fine porcelain vinyl porcelain veneers can provide a strong bond with the tooth, resulting in aesthetically pleasing naturalness that does not undergo other recreational opportunities.
Porcelain veneers are a great alternative to crowns or fillers in many situations. They provide a conservative approach to changing the color, size, shape, or position of a tooth. Porcelain veneers can mask unwanted defects, such as teeth stained with tetracycline, trauma or as a result of the root canal procedure, and are ideal for masking discolored fillings in the front teeth. Patients with gaps between the front teeth or teeth that are cut or wear can be treated with porcelain veneers. As a rule, veneers will last for many years, and this technique has shown remarkable durability when properly performed.
Patients may require several prescriptions for the entire procedure, including planning for diagnosis and treatment, preparation and adhesion. It is very important that you take an active part in the design of a smile. Spend time in making decisions and planning a smile. Understand the corrective limitations of the procedure for eliminating defects, color or position of teeth.
The appointment of the preparation will take from one to several hours. To prepare teeth for porcelain veneers, teeth are slightly reduced to provide a small added thickness of veneer. As a rule, about half a millimeter of tooth is removed, which may require a local anesthetic. With this appointment, a mold is formed from the teeth, which is sent to the laboratory for the manufacture of veneers. This can take from one to three weeks. If the teeth are too unsightly, a temporary veneer can be placed at an additional cost.
Gluing the veneer will take about one or two hours. First, the dentist places veneers with water or glycerin on the teeth to check their suitability and get a sense of shade or color. While veneers lean on your teeth, see aesthetic results and pay particular attention to color. At this point, the color of the veneer can still be adjusted with a hint of cement to be used. The color cannot be changed after gluing the veneers. To apply the veneer, the tooth is cleaned with special chemicals to achieve adhesion. As soon as a special cement is sandwiched between the veneer and the tooth, a visible beam of light initiates the release of a catalyst to harden the cement.
All porcelain restorations are called veneers when they cover only the front of the teeth. They are crowns when they cover all surfaces of the teeth. Restorations are three quarters of the crown when they do not cover the surface of the teeth towards the tongue. Часто бывает трудно отличить один тип реставрации от другого, и поэтому легче назвать их связанными фарфоровыми реставрациями.
Короны - передние и задние зубы
Короны используются для поддержки зуба, когда остается недостаточно оставшегося зуба, защищают слабые зубы от разрыва, восстанавливают сломанные зубы или покрывают плохо сформированные или обесцвеченные зубы. Корона - это реставрация, которая покрывает зуб как наперсток, чтобы восстановить его нормальную форму и размер, улучшая прочность и внешний вид зуба. Короны необходимы, когда зуб обычно разрушается, а начинки не решают проблему. Если зуб треснут, корона удерживает зуб вместе, чтобы запечатать трещины, чтобы повреждение не ухудшалось.
Чтобы подготовить зуб к короне, он уменьшится, чтобы крона могла поместиться над ним. Создается впечатление о зубах и деснах и отправляется в лабораторию для изготовления короны. Временная коронка устанавливается на зуб до тех пор, пока не будет создана постоянная коронка. При следующем посещении стоматолог удаляет временную корону и цементирует постоянную коронку на зуб.
Короны требуют большего удаления структуры зуба, следовательно, они покрывают больше зуба, чем виниры. Короны обычно обозначают для зубов, которые выдержали значительную потерю структуры. Короны изготавливаются из различных материалов, включая пластмассы, фарфоровые изделия и металлы или их комбинации.
Главная цель стоматолога - создать короны, которые выглядят как естественные зубы. Для достижения определенного взгляда рассматривается ряд факторов, таких как цвет, укус, форма и длина ваших естественных зубов. Когда процедура будет завершена, ваши зубы будут не только сильнее, но и могут быть более привлекательными.
Короны должны длиться около 12 лет. Тем не менее, при хорошей гигиене полости рта и надзоре большинство коронок будет длиться намного больше времени. Некоторые вредные привычки, такие как измельчение зубов, жевательный лед или укусы ногтей, могут значительно уменьшить этот период времени.
Во избежание повреждения или разрыва корон, избегайте жевания твердых продуктов, льда или других твердых предметов. Вы также хотите избежать шлифования зубов. Помимо посещения стоматолога и чистки зубов два раза в день, чистка между зубами жизненно важна для коронок. Для удаления зубного налета из зоны кроны важно, чтобы зубная паста соответствовала зубу. Бляшка в этой области может вызвать распад зубов и заболевания десен.
Замена отсутствующих зубов
Фиксированные мосты и имплантаты
Фиксированный мост заменяет отсутствующие зубы. Зубы по обеим сторонам пространства подготовлены для коронок. Короны соединены вместе, поэтому короны с обеих сторон могут поддерживать отсутствующие зубы посередине.
Имплантаты, обычно сделанные из титанового металла, аналогичного тому, который используется в штифтах для соединения с переломами костей, являются постоянными заменами отсутствующих зубов. Часть имплантата действует как корень зуба и поддерживает участок, который простирается над деснами. Заменяющие зубы могут быть постоянно закреплены на участках над деснами, например, на фиксированных мостах, или могут быть удалены аналогично перегрузкам.
Частичные зубные протезы
Частичные зубные протезы заменяют отсутствующие зубы, поддерживаемые деснами и оставшимися зубами. Съемные частичные зубные протезы обычно состоят из замещающих зубов, прикрепленных к розовым или смолистым основаниям смолы, которые соединены металлическим каркасом. Съемные частичные зубные протезы прикрепляются к вашим естественным зубам с помощью остатков, направляющих плоскостей и металлических застежек. Металлические застежки часто показывают, когда улыбаются. Зубной протез помогает вам правильно пережевывать пищу, улучшать речь и предотвращать провисание лица, обеспечивая поддержку губ и плеч. Полный протез удерживается во всасывании, поэтому функция скомпрометирована.
Overdenture - это протез, который использует прецизионные зубные насадки для удержания протеза. Наложение сверху может быть помещено в корни зубов, которые были сохранены или помещены на зубные имплантаты, которые были помещены для их приема. Когда правильные принципы дизайна улыбки применяются к протезам, они могут выглядеть очень естественно. Действительно, большинство пациентов с зубным протезом нуждаются в более несовершенных зубах зубов, поэтому они выглядят более естественными.
Полные протезы
Существует фундаментальное различие между полными зубными протезами и вашими собственными зубами, поскольку это всего лишь отсасывание, которое содержит полный протез на месте.
Зубцы могут двигаться или распускаться, когда язык, губы, плечи и мышцы нажимают на него. Хорошие впечатления обеспечивают точную подгонку и уплотнение по краям. Сохранению и стабилизации может способствовать форма кости и упругость десен, что затрудняет разрыв всасывания.
Трудно предсказать, как пациент будет адаптироваться к зубным протезам. Стабильный, удерживающий зубной протез увеличивает успех, но люди должны адаптироваться психологически и изучать методы работы с протезом. Образцы речи должны быть пересмотрены, и эффективность жевания может быть значительно уменьшена. По этим причинам полные протезы являются последним средством стоматологии.
Существует два варианта полных протезов: переутомления и имплантаты. Для стабилизации зубных протезов можно использовать случайные слабые зубы. Зубы, уменьшенные по высоте, намного сильнее, потому что силы ближе к деснам, уменьшая силу, вырабатываемую на их корнях.
Overdentures - это зубные протезы, которые укладываются на слабые зубы, уменьшенные по высоте после корневых каналов. Кроме того, прецизионные насадки могут быть размещены в этих зубах и протезах для дополнительного удержания. Сохранение корней также поможет поддерживать высоту кости, которая могла бы отступить, если бы корней не было.
