Abstract

The rapid prototyping technology helped to convert the virtual surgical plans into action by the help of fusion deposition techniques. Starch based polymers like PLA (Poly lactic acid) are commonly used in the field of tissue engineering for making scaffolds. In dentistry its use is limited because of lack of precision. We tried to make a 3D printed locator guide for surgical removal of impacted maxillary premolar by using a starch based polymer.

Keywords: 3D printing; Impacted maxillary teeth; PLA; Surgical guides.
