This study aimed to determine the association between facial biotype and the level of overbite in students at the Private University Norbert Wiener. The sample consisted of students aged between 18 and 43 years. Photographic records were taken in the frontal norm with the students in a natural head position. On the printed photographs, the facial opening angle was determined to establish the facial biotype. The vertical overbite record was clinically performed with the help of a Vernier caliper and a dermatographic pencil. Results: The distribution of facial biotype in the sample was 45.8% for dolichofacial, followed by mesofacial with 47.5%, and finally brachyfacial with 6.8%. Regarding overbite, deep bite predominated with 50.8%, followed by open bite with 40.7%, and normal bite with 8.5%, with no significant differences based on sex. In the dolichofacial group, deep bite predominated (27.1%), followed by open bite (18.6%). The mesofacial group had the highest frequency of deep bite (22%), followed by open bite (18.6%) and normal bite (6.8%). The brachyfacial group had the highest frequency of open bite (3.4%), followed by deep and normal bites at 1.7%. No statistically significant association was found (P > 0.05). Conclusion: Since no results responded to a specific pattern, it can be concluded that facial biotypes are not associated with the degree of vertical overbite.

The purpose of this research was to define the smile height in relation to facial biotype in students aged 15-17 at Huaycán Mixed School N° 1236, Peru, 2015. Facial height and width were measured clinically using a digital Vernier caliper, and photographs of spontaneous smiles were taken and evaluated. The study was observational, prospective, cross-sectional, descriptive, and relational. The sample consisted of 244 students who met the inclusion criteria. Data analysis was performed using the chi-square correlation test for related samples, with a 95% confidence level and a 5% margin of error. The results showed a significant difference in smile height in relation to facial biotype in both genders. Leptoprosopic (dolichofacial) students had high smile height, mesoprosopic (mesofacial) students had medium smile height, and euriprosopic (brachyfacial) students had low smile height. The difference was not significant for age. In conclusion, the results demonstrated that smile height should be applied according to facial biotype, as statistically significant differences were found.

Objective: To determine the relationship between facial biotype and smile types in patients attending the “Familydent” dental clinic in Lima, Peru, in 2021. Materials and Methods: The sample consisted of 106 individuals who visited the “Familydent” dental clinic in Lima, Peru, in 2021. Sampling was done in two stages. In the first stage, the individual's age, gender, and facial biotype were recorded using data forms. In the second stage, the smile types were completed after photographing the individuals. Results: 37.7% of the total patients had a leptoprosopic biotype with a low smile type, 48.1% had a leptoprosopic biotype with a medium smile type, and 8.5% had a leptoprosopic biotype with a high smile type. On the other hand, 94.3% of the individuals had a leptoprosopic biotype, 4.7% had a mesoprosopic biotype, and only one patient had an euriprosopic biotype. Regarding smile types, 42.5% had a low smile type, 49% had a medium smile type, and 8.5% had a high smile type. Conclusion: The significance value was (0.337), which is > (0.05), indicating that the null hypothesis is accepted and the alternative hypothesis is rejected. In other words, there is no relationship between facial biotype and smile types in patients attending the “Familydent” dental clinic in Lima, Peru, in 2021.

Association between facial biotype with the inclination of the lower incisor with respect to the mandibular plane with different skeletal patterns in cephalometric radiographs of patients of the odon clinic
(Universidad Privada Norbert Wiener, 2021-11-06) Vergara Cosme, Thalía Neyssa; Araujo Farje, Jessica Jazmin
The purpose of this study was to determine the association between facial biotype and the inclination of the lower incisor relative to the mandibular plane with different skeletal patterns in cephalometric radiographs. The sample consisted of 132 cephalometric radiographs (74 females and 58 males) aged between 14 and 40 years. The Ricketts’ Vert index was used to record and evaluate the five cephalometric values that determine the facial biotype, while the lower incisor inclination was measured using the IMPA angle, and the skeletal pattern was assessed using the ANB angle. Data were analyzed using the SPSS 21 statistical package, applying the Analysis of Variance (ANOVA) test and Pearson's Chi-square. Results: The most frequent facial biotype was mesofacial, accounting for 39.39% (n=52). The average inclination of the lower incisor was (93.89±7.63), and the most frequent skeletal pattern was Class I, with 43.94% (n=58). The female sex was the most frequent, with 56.06% (n=74), and the most frequent age group was 14 to 22 years, with 50.00% (n=66). It was also found that the greatest inclination of the lower incisor occurred in patients with a dolichofacial biotype (97.84±5.55). A significant difference (P=0.004) was found between skeletal pattern and facial biotype, with mesofacial biotype predominating in Class I, II, and III skeletal patterns. On the other hand, no significant difference was found in the interaction between skeletal pattern and sex, or age, regarding the lower incisor inclination (P>0.05). Conclusion: Patients with a dolichofacial biotype present a greater inclination of the lower incisor than those with mesofacial and brachyfacial biotypes. However, there is no statistically significant difference between skeletal pattern and the inclination of the lower incisor according to sex and age.

Association of the magnitude of antegonial curvature with facial proportion in patients of the private clinic in 2022
(Universidad Privada Norbert Wiener, 2022-12-13) Clavijo Chacón, Yoselyn Pamela; Morante Maturana, Sara Angelica
The purpose of this research is to establish the association between the magnitude of the antegonial curvature and the facial proportion to establish standard characteristics for a group of patients. Materials and Methods: 131 cephalometric radiographs of patients aged 8 to 15 of both sexes attending a private clinic were evaluated. All radiographs were traced with anatomical drawings on acetate paper, outlining the facial proportion according to Björk for evaluating the facial biotype and a tangent to the mandibular border to assess the depth of the antegonial curvature. These were then validated using the Spearman-Brown test with a 95% confidence level. Results: A positive correlation was found between the magnitude of the antegonial curvature and the facial proportion (p˂0.05), showing a downward inclination (rho=0.003). Conclusion: The evidence presented demonstrates that the evaluation allows identifying the association of the antegonial curvature depth with the facial proportion, showing a direct relationship.

(Universidad Privada Norbert Wiener, 2021-07-23) Campos Bastidas, Jacqueline Sonia; Del Castillo Ayquipa, Armando
The primary objective of this research was to determine the relationship between Occlusal Vertical Dimension (OVD) using the Ladda method and facial biotype in dentistry students at Universidad Privada Norbert Wiener. Methods: This descriptive and cross-sectional study included a sample of 201 students of both sexes, selected based on inclusion criteria. Facial biotype was determined using the total morphological facial index. Measurements were taken using a TRUPER digital caliper (150 mm x 0.01 mm). OVD was measured using the Ladda method, which involves the length of the index and little fingers of the right hand. Results: The study found statistically significant differences in OVD between at least two groups. Highly significant differences were observed between brachyfacial and mesofacial groups (p<0.05) and between mesofacial and dolichofacial groups (p<0.01). The study concluded that the dolichofacial biotype showed a high positive correlation with both the little finger and index finger. A general correlation was observed in both sexes between OVD and finger lengths. For males, OVD showed a low but significant correlation with the index finger (p<0.01) and the little finger (p<0.05). For females, OVD also showed a low but significant correlation with both the index and little fingers (p<0.01). Conclusion: This method is reliable, cost-effective, reproducible, and non-invasive for the patient.

Vertical dimension of occlusion and length of the fingers of the hand according to facial biotype in dentistry students at the Norbert Wiener University – Lima, 2023
(Universidad Privada Norbert Wiener, 2023-12-02) Escobar Roman, Flor De María; Vilchez Bellido, Dina
The objective of this study was to determine the relationship between the vertical dimension of occlusion (VDO) and the length of the fingers in dental students according to facial biotype. A correlational methodology was used, where morphometric data were collected from a sample of 157 undergraduate dental students, from the 8th to the 9th semester. The Facial Morphological Index (FMI) was used to describe the facial biotype of the students, considering facial height and width, determining the VDO, and classifying them into brachyfacial, mesofacial, and dolichofacial categories. Additionally, the length of the fingers on the right hand was recorded. The results showed that all correlation coefficients (Rho) between VDO and finger length measurements and the distance between the thumb and index were positive and statistically significant (p-value < 0.05). This indicates a positive and statistically significant correlation between VDO and finger length measurements and the distance between the thumb and index. In conclusion, this study supports the existence of a significant relationship between the vertical dimension of occlusion and finger length in dental students according to their facial biotype.
