There are three areas of your smile we look at to get the best aesthetic success
The first thing we do is analyse your face. This is done by looking at a few factors.
we look at your skeletal profile (your face shape from the side)
the cant of your arch (is you smile slanted and not straight)
The midline (middle of your teeth whether it meets the middle of your face)
The dynamics of your lips (when you smile, how much of your teeth do you show)
The amount of gums you show
The second thing we look at is you anterior smile (that is the smile in the fronts part of your mouth). This is done by looking at
horizontal position of the edges of your front teeth that is, are your teeth too far forward, too far back, too ling, too short)
vertical position of teeth ie is your smile line following the lip line, touching your lips or reverse. Also how much are you teeth revealed when you are not smiling.
Width to length ratio of your teeth. Generally the ratio is 80%
The height of the gingivae (gums) in relation to the ones on the adjacent teeth)
The shape of your teeth and therefore the shape of the space between your teeth called the embrasure.
The inclination of you teeth (are they straight or slanted and if slanted how much are they slanted)
The last thing we look at is your posterior smile (that is the way the smile blends with your back teeth)
Is there a space between you cheeks and teeth (buccal corridor)
The way your gums blend in with the back teeth
To analyse your smile there are a few things we need to know about your smile
How many teeth you show
The colour and shade of you teeth
Any stains, spots, discoloured areas on your teeth
Any spaces between your teeth
Any visible filling on you teeth
Any visible fillings and or crowns
Shape and size of your teeth
Do you show your gums when you smile like a gummy smile
How would you describe your lips
In the absence of facial harmony, the face is not initially viewed as a balanced unit. Instead, attention is drawn to the disproportionate parts of the face. This can be dark or misaligned teeth, spaces, gummy smiles, as well as disproportionate facial structures, such as lips, nose, and eyes in their relationship to each other and other facial features.
The concept of beauty has most often connected to harmony and harmonic proportions. The term "proportion" implies a mathematical expression of beauty.
While beauty cannot be measured, harmony - which is most often associated with beauty - can be expressed in formulas. Disregarding ornamentation such as make-up and hair style, facial harmony can be calculated according to such formulas, dictating a sort of a blueprint for the ideal human face.
Recent studies on the best-paid magazine models revealed the current ideal of facial aesthetics: A slightly protruding mouth profile, clear outline of bony structure, permanent display of upper teeth, short upper lip and, quite naturally, a seductive smile. Many of us are taught to believe that this ideal is out of reach. But the truth is that Aesthetic Dentistry can help us attain it.
The satisfactory division of a surface into parts that are different in shape and size yet are related to each other is called repeated ratio. The most significant repeated ratio in history is the "Golden Proportion (Golden Rules)".
The Golden Proportion results from the division of a straight line in such a way that the shorter part is to the longer part as the longer part is to the whole. Each ratio equals 0.618:
S/L=L/(S+L)=0.618
Linear progressions and surface division by the same number are common in nature both geometrically and arithmetically. The geometrical progressions can be obtained by multiplying each term by 1.618 or dividing by 0.618:
1.000 x 1.618 = 1.618 or 1.000 : 0.618 = 1.618
1.618 x 1.618 = 2.618 or 1.618 : 0.618 = 2.618
2.618 x 1.618 = 4.236 or 2.618 : 0.618 = 4.236
In the arithmetic progression each term is the sum of the preceding two terms:
0.618 + 1.000 = 1.618
1.000 + 1.618 = 2.618
1.618 + 2.618 = 4.236
As can be seen here, the progression using the Golden number is unique because three different methods produce the same results.
Obviously, the Golden Proportion is not the only parameter that defines harmony and therefore beauty. However, numerous studies and experiments have demonstrated that this surface division creates an aesthetic appeal, independently from ethnic or civilization factors.
The width of the central incisor is in golden proportion to the width of the lateral incisor (as seen from the front), which in turn is in golden proportion to the part of the canine that is visible from the front.
Even though the negative space escapes the attention of the public, it cannot be ignored. It creates a balance between cohesive and segregative forces in a smile and provides a harmonious relationship between the smile and other facial features. This example indicates that some fundamental principles are more easily perceived than others.
The presence of a lateral negative space gives depth and mystery to a smile, while its absence displays exuberance and brilliance paired with functional disturbances.
