The Ideal

Abstract Esthetics has been an ever-evolving concept and has gained considerable importance in the field of orthodontics in the last few decades. The re-emergence of the soft tissue paradigm has further catapulted the interest of the orthodontist. So much so that achieving a harmonious profile and an esthetically pleasing smile has become the ideal goal of treatment and is no longer secondary to achieving a functional dental occlusion and/or a rigid adherence to skeletal and dental norms. Esthetics in the orthodontic sense can be divided into three categories: macroesthetics, miniesthetics, and microesthetics. Macroesthetics includes the evaluation of the face and involves frontal assessment and profile analysis. The frontal assessment involves assessment of facial proportions, while the profile analysis involves evaluation of anterior–posterior position of jaws, mandibular plane, and incisor prominence and lip posture. Miniesthetics involves study of the smile framework involving the vertical tooth–lip relationship, smile type, transverse dimensions of smile, smile arc, and midline. Microesthetics involves the assessment of tooth proportions, height-width relationships, connectors and embrasures, gingival contours and heights, and tooth shade and color. The harmony between these factors enables an orthodontist to achieve the idealized esthetic result and hence these parameters deserve due consideration. The importance placed on a pleasing profile cannot be undermined and the orthodontist should aim for a harmonious facial profile over rigid adherence to standard average cephalometric norms. This article aims to give an overview of the macro, mini, and microesthetic considerations in relation to orthodontic diagnosis and treatment planning.

Introduction: In ancient days, it was believed that attractive and harmonious faces were having certain fixed proportions known as neoclassical canons. These canons were used extensively by Leonardo Da Vinci, Durer in their art during renaissance. They served as guidelines for artists as well as for aesthetic surgeons for centuries and proved to be helpful till now. From ancient days to modern era, the exact formula of beauty is not yet calculated. The norms of beauty changes from country to country and race to race. A face is beautiful and shows harmonious features if the individual components are proportional, this is what is referred as facial balance. In ancient Greece, they calculated the formula for creation of art and these formulae are called as neoclassical canons. The classical Greek canons of facial balance are still foundation of modern reconstructive and aesthetic surgery. Aim: To check the validity of neoclassical canon in Western Maharashtrian population. Materials and Methods: This was an observational type of study carried out from March 2018 to January 2020. The validity of Naso-oral canon was checked in Western Maharashtrian population. According to this canon ideal mouth width (ch-ch) (mouth width (distance between right and left corners of mouth called chelion)) is 1.5 times of Nose width/alar width (al-al) (alar width (distance between right and left ala of nose)). Mouth width=1.5 times of Nose width. However, the mouth width can be less than 1.5 times of nose width or mouth width can be greater than 1.5 times of nose width. This study was carried out in the five cities Sangli, Kolhapur, Islampur, Karad and Satara of Western Maharashtra, India. Total 1500 male and female students, 300 from each city, between the age group of 18-20 years were selected. Measurements were taken with the help of digital Vernier caliper. The methodology adopted for the measurements was taken from the guidelines given by Farkas LG in his book- “Anthropometric facial proportions in Medicine”. Results: In present study, total 68.33% subjects including males and females were having mouth width (ch-ch) lesser than one and half times of nose width/alar width (al-al) i.e., ch-ch <1.5 (al-al). Remaining 31.67% subjects were having mouth width greater than one and half times of nose width/alar width i.e., ch-ch >1.5 (al-al). Conclusion: Naso-oral neoclassical canon was not found valid in Western Maharashtrian young adults. In 78.32% male and 62.80% female population of Western Maharashtra, mouth width was found lesser than one and half times of nose width.

ABSTRACT Background Selecting and replacing missing teeth to natural proportions and esthetic preference of a patient in the absence of pre-extraction records is a very challenging task. Although facial analysis and proportions are well discussed in many populations, none exists for the Thrissur, Kerala, population. A prosthodontic rehabilitation for Kerala patients relying on other racial norms may result in dissonant facial proportions. Therefore, the purpose of this study was (1) to evaluate the validity of innercanthal distance as a guide in determining the mesiodistal dimension of six maxillary anterior teeth in a selected Malayalee population in the Thrissur Municipal Corporation area; (2) to check whether innercanthal distance undergoes dynamic changes over time as a result of aging; and (3) to evaluate whether there is a gender difference in the analyzed mean facial and dental proportions in this population. Materials and methods The study was conducted on 1,200 subjects in the Thrissur Municipal Corporation area. From five wards, 240 subjects were selected, out of which 120 were from the 18 to 25 years age group and 120 from the 40 to 50 years age group. Sixty males and females were selected from each group. The innercanthal distance was measured using a Digital Vernier Caliper, and alginate impressions were made to evaluate the size of maxillary anteriors. The data was analyzed statistically. Results The study showed that there is a high statistical significance between the innercanthal distance and the mesiodistal width of six maxillary anterior teeth in females (p < 0.01) and no significance in males. There was also dynamic changes in the innercanthal dimension and the mesiodistal width of maxillary anteriors with increase in age (p < 0.001). The difference in the mean of innercanthal distance between the genders was highly statistically significant, but no significance was found between the genders in the mesiodistal width of maxillary anteriors. Conclusion Within the population evaluated, there was a high statistical significance in females between the innercanthal distance and the mesiodistal width of six maxillary anterior teeth, but not for males. Innercanthal dimension was found to undergo dynamic changes as age increases in both males and females, and it was much higher in males than in females. There was no statistical significance in the comparative evaluation of mesiodistal width of maxillary anteriors of males and females in the study. Clinical significance Teeth selection is a critical step in determining the outcome of successful prosthodontic treatment. No definite guidelines for the selection of maxillary anterior teeth pertaining to the Thrissur, Kerala, population exist. A prosthodontic rehabilitation of Thrissur, Kerala, patients relying on other racial norms will result in dissonant facial proportions. In selecting maxillary anterior teeth, the knowledge of racial norms will help specify certain esthetic and functional modifications in treatment plans, which might be specific to each group. Therefore, there remains an unquestionable need for a scientific and reliable method for maxillary anterior teeth selection, which can be applied on this group of Indian population.

Background: Esthetics is the primary consideration for patients looking for prosthetic treatment. Determining the facial types of Thai populations is important because most studies conducted in Caucasian populations mention their facial types, and describe the gender comparisons, and GP of the teeth. Objectives: This study compared facial proportions, analyzed the maxillary anterior teeth proportions and determined the relationships between teeth with facial measurements using the Golden Proportion (GP) and Golden Standard (GS) in a Thai population. Methods: A total of 200 students (18-35 years) with well-aligned maxillary anterior teeth participated in this study. Face heights and widths were measured from the face using digital calipers and faces were classified as narrow, average, and broad. Teeth and face proportions were compared with GP and GS. One-way ANOVA was performed to compare maxillary anterior teeth proportions and facial proportions with different face types (α= 0.05). Pearson’s correlation was used (α= 0.05) to determine the correlation between facial proportion and teeth dimension among different facial types. Results: The findings showed 82.50% narrow face, 13.50% average, and 4% broad face among Thai subjects. No GP or GS was found in the face and anterior teeth, but teeth and face proportions other than GP and GS were found. No significant correlation was found between the Width of the Central Incisor (WCI) with interpupillary distance and alar width. Conclusion: In this study, the GP was not found in the facial and teeth proportion. The data obtained from this study may help to provide guidelines for prosthetic and orthodontic management and help to select the proper size and form of the maxillary anterior teeth to achieve proper esthetic outcomes in the Thai population.

Aim. To find thresholds at which laypersons and dental professionals perceive abnormalities in two facial frontal esthetics variables: facial symmetry and vertical harmony. Materials and Methods. A baseline frontal image of a young male face with optimum facial proportions was generated from a real image using a photo editing software. Different facial asymmetry images were then generated from this image by manipulating the chin point position at 2 mm increment to the left side. Vertical harmony was perceived through manipulating lower anterior facial height (LAFH) at a ratio of 2% of increased and decreased heights. A total of 120 raters divided equally into four groups of laypersons, general dental practitioners (GDPs), orthodontists, and oral and maxillofacial surgeons (OMFSs) rated these images using an analog scale of 100 mm long. Using ANOVA and Tukey post hoc tests at P < 0.05 , the image that showed the first statistical difference compared to the baseline was considered as a threshold of abnormality. Results. The image of 4 mm asymmetry was defined by the laypersons and GDPs as the threshold of abnormality, while the orthodontists and OMFSs realized that at 2 mm. Laypersons and GDPs defined a threshold of 46% as an abnormal decrease in the LAFH and the other 2 groups at 48%. All dental professionals groups rated the image of 54% as an abnormal increase in the LAFH while laypersons perceived that at 56%. Conclusion. These thresholds regarding frontal esthetics may contribute to the process of establishing proper orthodontic treatment planning that suits the highest facial esthetic standards.
