Smile Design Principles or Smile Design for Cosmetic Dentistry

A smile design influences the overall cosmetic impact of an person’s smile. Smile design can be divided into four separate components:

-Facial Esthetics.  A person’s facial esthetics varies greatly from patient to patient. A cosmetic dentist can evaluate this using a visual examination and the use of photography. Facial Esthetics will include not only the teeth but also the bone structure of the face and the musculature. It will also inlcude the way your lips frame your smile when you speak, smile, or laugh.

-Gingival (Gum) Tissue Esthetics.  A smile with diseased gum tissue will never bo one that is considered attractive. Healthy gum tissue is an essential element in smile design. Common  cosmetic dentistry  complaints include a gummy smile, uneven gum tissue, and exposed root surfaces from recession. All of these things take away from a person’s smile appeal.

-Microesthetics.  This component deals with the subtle attributes that make your teeth appear the way they do. This includes how they reflect light, any unique marks or colorations. This technique is applied when restoring a tooth from decay. Cosmetic dentistry will restore the tooth to give it qualities closely resembling the natural tooth. The anatomy and coloration of natural teeth is a unique quality that varies from patient to patient.

-Macroesthetics.  This area allows the cosmetic dentist to analyze the relationship and proportions between a patient’s front teeth, surrounding tissues, and facial characteristics. Analyzing these characteristic will ensure the final result will be natural and attractive for the patient. Working together, your cosmetic dentist and dental laboratory technician combine their technical and artistic abilities to create a natural and esthetically pleasing appearance in which the shapes, sizes and arrangement of individual teeth blend with and complement your

particular features.

Anatomy of a Smile in Cosmetic Dentistry

The following are the important anatomical structures or landmarks used in cosmetic dentistry:

- Lips. In  cosmetic dentistry  the lips are usually compared to a picture frame. The lips frame your smile, teeth, and gums. Lip enhancements correcting shape, fullness, and symmetry of your lips can make your smile seem broader and fuller.

For optimal cosmetic effect, your facial features should line up to your teeth and lip lines. When your lips form a broad smile, an imaginary line can be drawn through the corners of the mouth, from one side to the other. The amount of upper front (maxillary anterior) tooth revealed below this line helps create a vibrant, youthful image. In a youthful smile, the upper front teeth should fill between75-100% of the space between your upper and lower lips in a full smile.

- Midline. The facial midline is an important landmark in cosmetic dentistry. It is an imaginary vertical line drawn between the front two upper teeth. For optimum esthetics the facial midline should line up with the middle of the face.

Sometimes facial features can throw the midline off. These include the eyes, nose, and chin. A portion of the population has uneven eye levels or a nose that is slightly off center. If not taken into account this will throw the whole analysis off.  Cosmetic Dentistry  uses a more accurate landmark on the face. The point between the eyebrows and the cupid’s bow in the center of the upper lip is used. By using these two landmarks, cosmetic dentists can draw and locate the facial midline wile also determining its direction.

Whenever possible, the midline between the upper front teeth (central incisors) should coincide with the facial midline. In cases where this is not possible, the midline between the central incisors should be perpendicular to the imaginary line that could be drawn through the corners of the mouth.

- Smile Line. Your smile line is the line created by the top of your lower lip. In an ideal smile line, the edges of your upper teeth should be parallel to your lower lip when you smile. The bottom of your lower lip should have the same line as the gums of your lower jaw. This should always be a standard, regardless of the size or shape of your smile. Once your cosmetic dentist has determined the orientation of your smile line, they can design its curve, or shape, and determine the length of your new restorations for your  smile makeover.

- Teeth. Smiles that tend to be considered attractive usually hve a few things in common. These features include white teeth, teeth that are unstained, and evenly spaced with no crowding.

Upon smiling, your top teeth show fully in a good proportion to your gums. The line where the gums and teeth meet is smooth and even. The smile line of the upper teeth follows the curve of the lower lip. The midline of the upper front teeth ideally is in the center of the face. Tooth reveal is a term that describes the amount of tooth structure that shows during smiling and various angles of your face.

Cosmetic Dentististry  Variations

The impact of a smile cannot be judged just by the individual beauty of teeth and gums. Each and every patient has their own unique qualities, quirks, and traits. These include age, sex, personality traits, as well as cosmetic dentistry expectations.

When considering  person’s ideal smile, the cosmetic dentist will always consider an individuals personal traits. These include facial features, skin tones, hair color, as well as how your teethare framed by your overall appearance. Occlusal and functional considerations will also play a role in the final treatment.

Macroesthetic concepts provide only guidelines and reference points for beginning esthetic evaluation, planning and treatment. The artistic component can be applied and

perfected in cosmetic dentistry by dentists who understand the rules, tools and strategies of smile design. In modern  cosmetic dentistry  there are tools such as digital imaging, lasers, teeth whitening procedures that allow a skilled cosmetic dentist to create smile makeovers.

The cosmetic dentistry procedures range from  teeth whitening  to  dental bonding  to  porcelain veneers, crowns, and  dental implants. Cosmetic dentists also have at their disposal the ability to augment soft tissues. The use of dermal fillers can correct certain facial feature such as thin lips or even facial asymmetry. Advances in cosmetic dentistry and sedation dentistry make it possible to do these procedures with less patient anxiety and pain.

Ultimately any cosmetic dentistry smile makeover is in the eye of the beholder. Just because certain procedures are possible it does not mean it should be done on each and every patient. Many patients embrace their uniqueness and are fine with the way they look. Others are looking for a change and thats where  cosmetic dentistry  can come in and make that happen for them.
