An In-vivo Comparison of Vertical and Horizontal Distance between Incisive Papilla and Incisal Edge of Maxillary Central Incisors in Dentates with Different Arch Forms ZC97-ZC100

摘要

Introduction: The incisive papilla is one of the most stable landmarks for assessing the original position of certain key teeth. To place anterior artificial teeth back in its original position such as in denture construction and full mouth rehabilitation cases vertical and horizontal distance from incisive papilla in different arch forms, imparts a significant role. The average distance will be helpful for arrangement of teeth in its original position which not only provides a pleasing appearance and normal function but also will save the dentists? chair side effort.Aim: To determine the average vertical and horizontal distance of the maxillary central incisors from the incisive papilla in dentate individuals with different arch forms.Materials and Methods: Primary impressions and casts were made for 72 dentate patients, sorted into different arch forms and mid point of the incisive papilla was established. The vertical and horizontal distances were measured with the digital vernier caliper. The mean and standard deviation were subjected to Students t-test.Results: The range of horizontal distance was 4-7 mm, 6-8 mm, 5-8 mm and vertical distance was 4-6 mm in ovoid, square and tapered arch forms respectively.Conclusion: Horizontal distance of the maxillary central incisors from the incisive papilla varies in different arch forms whereas, vertical distance is almost same in all the arch forms.
