“Beauty is in the eyes of the beholder”. At the same time, when we examine the roman concept of the Golden Proportion, we realise that this arithmetic and aesthetic rules of divine beauty was universally accredited in the early era of Leonardo Davinci. Since then, the smile guided rules of proportions have been the centre of classic facial cosmetic surgery and aesthetic dentistry.
The parameters of a beautiful natural smile could be analysed and evaluated based on many tooth-related factors, among which the followings are being mostly taken into account:
Teeth Colour: Teeth discolouration is a continuous and gradual natural process caused by some drinks, smoking and tooth wear. It is a common fact that bright, clean tooth colour is important for a confident good look. Therefore, teeth whitening and, in some cases, the ceramic veneer provision is considered an effective approach to treat the darkened and surface -damaged teeth and brighten your smile.
Proportions: the ideal proportion of the teeth width and length, and their position with each other, the relative dimensions of the smile corridor and window and the other facial components should give a spontaneous pleasant sensation within the beholder. The concept of golden proportion has prevailed in the field of cosmetic dentistry and orthodontics for decades. Orthodontic tooth-movement can change the tooth length by aligning the tooth position in dental alveoli.
On the other hand, periodontal gum correction may increase or decrease the gum and, consequently, the tooth length.
Teeth Symmetry refers to a mirror-imaged 3-dimensional positioning of the teeth on each side of the mouth, while the central line of the upper and the lower arch should coincide with the vertical facial midline.
Teeth Alignment and spacing: The orthodontic tooth-movement aims to realign the dentition 3-D position, alignment, and symmetry, while the provision of the ceramic veneers camouflages these features without treating them.
Teeth Size: Tooth size proportional discrepancies may be rectified by non-invasive composite sculpturing or, more comprehensively, by the provision of the ceramic veneers.
