New tray design in prosthetic management of patients with systemic sclerosis: a clinical report

Abstract

Aim: A partially edentulous 28 years-old female suffered from microstomia and hardness of the skin caused by systemic sclerosis. For prosthetic rehabilitation, Elsherbini’s Double Spring tray (EDS tray) was fabricated. EDS tray was fabricated by self-cured acrylic resin, during the dough stage, the tray was cut into two halves, then two springs were placed on the labial and lingual aspect of the tray. The idea of the EDS tray is that it can be bent to be easily inserted into the microstomia, once in the oral cavity the push action of the two springs will allow opening of the tray to the original shape. The impression was taken Impregum 3m Impression material. The impression material used should be flexible with high tear strength, to ensure good accuracy of the impression. Elsherbini’s Double Spring tray can be an effective design in the rehabilitation of patients with microstomia, due to its simplicity of fabrication, cost effectiveness, and high accuracy.
