Ortodontide Kullanılan Şeffaf Plakların Su Emilimlerinin ve Renklenmelerinin Değerlendirmesi

Amaç: Şeffaf plak kullanan hastalarda termoplastik malzemede oluşabilecek renk değişikliklerini önlemek amacıyla, hastalara su hariç her yiyecek ve içecek tüketimleri sırasında plaklarını çıkarmaları önerilmektedir. Ancak yine de günlük hayatta bazı hastalar, özellikle içecek tüketimi sırasında plaklarını çıkarmadan günlük rutinlerine devam etmektedir. Bu durumda termoplastik olan şeffaf plakların fiziksel özelliklerini etkilemektedir. Termoplastik malzemelerinin fiziksel özellikleriyle ilgili çok az çalışma vardır. Hastaların bilgilendirmesi açısından literatürde yeterli sayıda yol gösterici kanıtlar bulunmamaktadır. Bu çalışmada amaç, şeffaf plakların boyar ajanlara maruz bırakıldıktan sonra oluşan renk değişikliklerinin karşılaştırmalı olarak incelenmesidir.

Evaluation of Water Absorption and Color Stability of Clear Aligners Used in Orthodontics

Aim: Patients using clear aligners remove their plates during every food and beverage consumption, except water, in order to prevent color changes that may occur in the thermoplastic material. However, in daily life, some patients continue their daily routines without removing their aligners, especially during beverage consumption. In this case, it affects the physical properties of the thermoplastic clear aligners. There are very few studies on the physical properties of thermoplastic materials. There is not enough guiding evidence in the literature in terms of informing patients. The aim of this study is to comparatively examine the color changes of clear aligners after exposure to staining agents.
