(Universidad Privada Norbert Wiener, 2023-07-06) Chávez Hernández, Richard Percy; Guevara Sotomayor, Juan César
Objective: The aim of this research was to compare the occlusal vertical dimension as determined by the Knebelman method and the Willis method in adult patients. Methodology: An inductive method with a quantitative approach was applied. The research was correlational. The sample consisted of 66 adult patients treated at the Odontofresh Dental Clinic, where measurements were taken according to the Knebelman and Willis methods, as well as determining the distance between the base of the nose and the chin. Results: It was found that the average distance between the base of the nose and the chin was 50.67 mm in women and 51.21 mm in men. According to the Knebelman method, the most accurate results were 64.03 mm in women and 64.94 mm in men. According to the Willis method, the results were 48.7 mm for women and 4.39 mm for men. The Wilcoxon signed-rank statistical test showed a significance of 0.000 and 0.002 for the Knebelman and Willis methods, respectively. Conclusion: There are significant differences between the occlusal vertical dimension and those determined by the Knebelman and Willis methods in adult patients at Odontofresh Clinic in 2022.

Evaluation of the occlusal vertical dimension by cephalometric analysis in dentate patients treated at the Norbert Wiener University Dental Center, 2023
(Universidad Privada Norbert Wiener, 2024-06-06) Lobato Avila, Elvis Luis; Guevara Sotomayor, Juan César
This thesis aimed to evaluate the occlusal vertical dimension (OVD) through cephalometric analysis in dentate patients treated at the Dental Center of the Universidad Norbert Wiener in 2023. A quantitative, applied, non-experimental, and cross-sectional study design was used. A total of 31 lateral cephalograms of adult dentate individuals were analyzed to establish the OVD, using a data collection sheet through the observation technique of the cephalometries. The first step was to verify general characteristics such as age and sex, then measure the distance from the tip of the nose to the tip of the chin, and finally, the occlusal vertical dimension was established through cephalometric analysis. It was observed that regarding OVD through cephalometric analysis, the upper angle showed a maximum value of 640 and a minimum of 400, with a mean of 51.640; the middle angle had a maximum value of 620 and a minimum of 260, with a mean of 48.030, and the transferred lower angle showed a maximum value of 590 and a minimum of 410, with a mean of 49.640. It was concluded that the occlusal vertical dimension through cephalometric analysis in dentate patients treated at the Dental Center of the Universidad Norbert Wiener in 2023 was an upper angle mean of 51.640, a middle angle mean of 48.030, and a transferred lower angle mean of 49.640.

Relationship between the facial biotype and the vertical dimension in patients of the Ortoexcelencia dental clinic in the year 2021.
(Universidad Privada Norbert Wiener, 2022-11-25) Diapis Perez, Milagro del Carmen; Guevara Sotomayor, Juan César
The sample consisted of 168 patients who visited the dental clinic. Each patient was carefully informed about the present research, and after the patient's consent was obtained, the informed consent form was provided. Points of reference were marked on the face, and the required measurements for determining the variables were taken using a digital caliper. The results were recorded in a data collection form. Methodology: This study was conducted using a database in the Excel program, with graphs and tables provided. For statistical and analytical data, the SPSS 25 program was used, followed by statistical analysis. Results: The research results showed that the occlusal vertical dimension, determined by the Knebelman method, was 72.9 mm for the right eye-ear measurement and 72.8 mm for the left eye-ear measurement. The occlusal vertical dimension in rest position was found to be 69.9 mm. Facial biotype was determined according to gender, with the following results: in females, 93% had a dolichofacial biotype, 2.3% had a mesofacial biotype, and 4.7% had a brachyfacial biotype. In males, 92.7% had a dolichofacial biotype, 4.9% had a mesofacial biotype, and 2.4% had a brachyfacial biotype. Conclusion: The facial biotype is not significantly related to the vertical dimension.

Relationship between two anthropometric studies regarding the occlusal vertical dimension of young patients from a teaching clinic in Lima, 2023
(Universidad Privada Norbert Wiener, 2024-07-12) Alzamora Alvarado, Roxana Vilma; Gómez Carrión, Christian Esteban
The purpose of this study was to determine the relationship between two anthropometric studies regarding the occlusal vertical dimension (OVD) of young dentate patients at a teaching clinic in Lima, 2023. A non-experimental, quantitative, correlational, and cross-sectional methodology was used, with a sample of 109 patients from the dental clinic of Universidad Norbert Wiener (UNW), Lima. The results revealed that regarding the relationship between the two anthropometric studies and the OVD of young dentate patients, the OVD had an average of 44.5mm. In the anthropometric study of hand fingers, the index finger had an average of 62.1mm, the pinky 44.5mm, and the index-thumb distance 64.3mm. In the anthropometric study of the auricular pavilion, the right side had an average of 61.6mm and the left side 62.3mm, verifying that the averages of the pinky finger are closer to the OVD. The statistical analysis demonstrated a significant relationship between the studied variables (p=0.00) with a Pearson coefficient between the OVD and the hand fingers ranging from 0.440 to 0.515, and between the OVD and the auricular pavilion ranging from 0.385 to 0.355. It is concluded that there is a moderate relationship between the two anthropometric studies regarding the OVD of young dentate patients at a teaching clinic in Lima, 2023.

Relationship of the occlusal vertical dimension by means of the Ladda method according to facial biotype, in dentistry students of the Norbert Wiener private university
(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.
