Abstract

Background: Digital technologies are very useful in dentistry. It can be found in every of its brands. Materials and Methods: Twenty-one patients in the retention phase after orthodontic treatment were studied. The gender distribution was almost even- 10 boys (47.6%) and 11 girls (52.4%). Patients were aged 15 to 35 years, with a mean age of 19.71 (± 6.27), of which 76.2% were under 18. At the start of orthodontic treatment, 14 patients were with Angle Class I and 7 with Angle Class II. 14 (66.7%) were treated without extractions, 7 (33.3%) with extractions. An intra orals can was performed using Trio’s color (3 Shape, 2014). The digital models are used to create the retainer using 3 shape design software-splint studio. T-Scan Novus was used to check occlusion. Descriptive statistical methods were used to assess the demographic and clinical characteristics of the study group. Counts and percent ages were used for the categorical variables. The study aims to establish the occlusal force distribution by quadrants during the placement of orthodontic retainers printed from a biocompatible material. Result: The dentition was divided into four zones- two frontal and two distal the mean forces were: Right distal 37.14%, right frontal 11.4%, left frontal 11.46% and left distal 39.99%. A statistically significant difference was found between the frontal and distal regions, but not between the left and right halves. Conclusion: The uniform balanced contacts obtained in a digital design are uniform in distribution but not in force. The distal sections are significantly more loaded than the frontal sections at uniform design contact.
