The First Case Report about Noninvasive Impression Taking in Orthodontic Patient with Epidermolysis Bullosa

Bullous epidermolysis (BE) is a rare genetic disease that manifests itself already in early childhood, resulting in impaired expression of protein genes responsible for the connection of skinlayers / mucous membranes.An 11-year-old girl suffering from simple Bullous Epidermolysis (BE) needed orthodontictreatment. The method for obtaining “digital” prints using optical scanning was chosen as themethod for obtaining atraumatic negative tissue imaging in the zone of interest. The scanner usedin this clinical case works on the principle of triangulation. Understanding the degree of skin andmucosa sensitivity of the patients with BE to the mechanical stimuli is important for making a choiceof getting information about dental arch and ways of taking the impression at the initial stage oftreatment planning. Taking-off the traditional highly-accurate impressions by polysiloxane-basedimpression materials in patients with BE were excluded because this method involves taking animpression in two stages to achieve a better result. An option to cast impressions with polyesthermaterial, given its high thixotropy was also considered. But with that option there would bedifficulties in extracting such an impression from the oral cavity due to the hardness of the materialafter the end of the polymerization process, which was attributed to a high risk of tissue trauma.Intraoral scanning is the only atraumatic way to obtain the information about the teeth andmucous membrane health in patients with its pathology due to epidermolysis bullosa.
