Abstract:

Purpose: Periodontal spots are used for purposes such as protecting the wound area from sputum, mechanical irritations and bacteria from accumulation. The deterioration of the dimensional stability of the paths can lead to bound leakage, accumulation of bacteria and plates. The purpose of this study is to study the dimensional change in periodontal paths in a three-dimensional way in terms of time, heat and thickness. It is divided into 16 pieces of 1x2 cm size and 8 pieces of moist (37°C) and 8 pieces of room temperature (25°C) in 2 groups. The patterns are designed using the Microsoft 3D Builder program so that they will be reference points for spacecraft 2, 4, 6 and 8 mm depths and 3D comparison. The 4K DLP SLA printer is designed with the model rhinese. The pates are prepared on a glass surface until the homogeneous color is obtained for 45 seconds. It was handled with a handheld and placed on the vacuum. The measurements were made with the Sirona Inneos blue laboratory scanner. The STL file has been used. The measurements were made at 1, 2, 3, 6, 10, 12, 24, 36, 48, 60 and 72, 84, 96, 108 and 120. The size change is measured with Cloud Compare v2 software. In the statistical analysis, Graphpad Prism version 9 was used. Two-way ANOVA has been used. Results: Time-related dimensional change has been statistically meaningful in all groups (p<0.001). The groups at room temperature in less thick samples showed more changes than those in moist environment. As the thickness of the patch increases, the samples found in the moist environment have been found to show more changes. Results: Periodontal pates have been found to show time-related dimensional changes. Other studies on the impact of this change on stability are needed.
