Custom Sectional Impression Tray With Sectional Handle for Microstomia Patients

Abstract

Microstomia presents a unique challenge to the dentist as well as the patient. Microstomia patients often face difficulty in inserting or removing removable dental prostheses due to constricted opening of the oral cavity. Dentists often face difficulty in inserting impression trays in these patients because of the limited mouth opening. Standard impression procedures need to be modified in such patients. This article describes a simple design for the fabrication of a sectional handle for a definitive impression in microstomia patients. The sectional handle could be sterilized and reused.

Sectional Impression Tray With Reusable Handle: A Single Solution for All Microstomia Cases

“…Lego blocks [ 4 , 7 ] and locking levers [ 9 ] were used for the fabrication of mandibular sectional impression trays, but their use in maxillary sectional impression trays was questionable. It can also be used for both edentulous as well as dentulous patients for making an impression of both arches.…”

“…The insertion of a standard stock and custom impression tray presents initial difficulty in prosthetic rehabilitation. Various sectional impression trays are described in the literature [4][5][6][7][8][9]. These sectional tray designs are successful in making an accurate impression, but every time a new case comes to the hospital, a new tray design needs to be planned instead of using a standardized design for all patients.…”
