Relationship between Anterior Teeth Sizes and Facial Dimensions in Dentate Patients
Abstract
Background and purpose: Esthetics is a major purpose in prosthetic treatments. Choosing the right size of anterior teeth in prosthetic and edentulous patients is a major challenge for both the patient and the dentist. This study was designed to obtain approximately close ratios for selection of anterior teeth. Materials and methods: This descriptive-analytical study, was performed in 121 patients. Measurements were performed using Vernier Caliper in contact with the soft tissue of the face with minimal pressure. Measurements were made while patients were in an upright position and their head was in a normal position. All patients occlusion was placed in centric relation (CO), and their lips were in resting position. The average amount of three measurements was recorded as the final result. SPSS V25 was applied for statistical analysis. Results: There were significant positive relationships between the size of anterior teeth and the distance between the two nasal tips (P=0.037) and between two nasal tips and canine to canine distance (P=0.014). No significant relationships were found between the size of anterior teeth and the distance between two zygomatic arches (P=0.947) and between the width of the anterior teeth and the distance between the internal and external meatus (P=0.297, P=0.952, respectively). Conclusion: The average size of facial and dental parameters was found to be different between men and women. The width and height of the face and the width and height of the maxillary central teeth were higher in men than women.
