“…Londono et al in 2022 evaluated the golden ratio in natural facial esthetics. While, this study demonstrated no conclusive relationship between facial esthetics and the golden ratio across all ethnicities, the alignment, symmetry, and proportion of the face, which are fundamental elements of facial beauty, are still frequently assessed using the golden ratio in facial analysis (19). Moreover, according to a Stevens et al study in 2021, the golden ratio is a useful tool for facial analysis and dorsal preservation rhinoplasty, which is a surgical procedure that tries to maintain the nose's natural form while enhancing its esthetic (20).…”

Esthetic dentistry is a field of dentistry that focuses on enhancing the individuals’ esthetic, oral function, and health. One of the tools that have been used is the golden ratio which is a mathematical concept with substantial application in facial and dental esthetics. Some studies showed that this proportion affects people`s esthetic. Therefore, using the golden ratio can be beneficial for improving individuals’ facial and dental esthetic when it combines with other procedures such as implants and gingival recession treatment.

Objectives Using finite element analysis (FEA), this study aimed to determine the effect of nonrigid connectors (NRCs) and their position on the success of tooth and implant-supported fixed prostheses in the maxillary posterior region. Materials and Methods Three three-dimensional FEA models were designed, presuming maxillary second premolar and first molar to be extracted. Implant (replacing first molar), abutment, bone (spongious and cortical), first premolar (containing dentin, root cement, gutta-percha, and casting post and core), periodontal ligament, and three three-unit cemented porcelain-fused-to-metal prostheses (a rigid one and two nonrigid) were modeled. The NRC was once on the tooth side and once on the implant side. The prostheses were loaded twice. The first molar (180 N) and premolars (120 N) teeth were subjected to progressive vertical and oblique (12-degree) loads, and maximum von Mises stress and strain in teeth and connectors were calculated for each model. Results The findings of the current study showed evidence that tooth-implant design with an NRC has significantly increased the average stress in the tooth. The average stress in dentin was 769.02 for the mesial connector and 766.95 for the distal connector, and this was only 731.59 for rigid connector. Furthermore, it was observed that rigid connector has considerably minimized the stress within the tooth–implant-supported fixed partial denture. The average stress for the crown and metal frame is 346.22 and 526.41 in rigid connector, while it is 1,172.9 and 2,050.9 for the nonrigid mesial connector. Conclusion Although distal NRC was more efficient than mesial NRC, using NRC will only reduce the stress applied to cortical bone and is not recommended in the posterior region of the maxilla.

Beauty is achieved when using the concept of balance. Several authors have suggested that delicate facial appearance has optimized proportions correlated with the golden proportion. Some authors recommended the application of the golden ratio theory to correlate the successive wideness of the anterior teeth, as observed from the labial angle. It was also revealed that the central incisor width must be in golden proportion to the wideness of the lateral incisor and that the lateral incisor must be in golden proportion to the wideness of the canine whenever examined from the front. Various studies have supported the application of divine proportion in dentistry. The primary objective of this mini-review is to outline the relationship between facial esthetic and divine proportion and highlight the use of rhinoplasty for facial esthetics.
