Skeletal Dental Typology: An Analysis Based On The Fibonacci Sequence

Abstract

Objective: The aim of this study is to analyze descriptively the skeletal dental typology based on the Fibonacci sequence and to describe the proportion that this entails in terms of the standard of esthetic beauty in dentistry.

Method: The study was carried out under an adequate bibliographic review in different databases and it uses a descriptive research with a quantitative approach. The starting point was the definition of the Golden ratio and the recurrence function in its usual and explicit form, which helps to describe the numerical succession.

Results: It is established that the esthetic anterior teeth become narrower by about 40% as they move away from the midline in the upper dental arch. According to Ricketts' results, the width of the central incisor should be 1.618 and the with of the canine 0.618. In order to describe a standard skeletal tooth typology, the lingual lip of the central incisors is absolute and the precise trajectory may vary in a nondependent manner depending on the skeletal typology.

Conclusions: Finally, the sequence in Fibonacci numbers shows the same proportion, justifying the reliability of this succession in the dental field and concluding that skeletal dental typology and occlusion of teeth contain a majestic, innate beauty.
