The present disclosure envisages process for preparing a metal base for orthodontic applications. The process comprises the steps providing a metal substrate etching the metal substrate to obtain an etched metal substrate disposing the etched metal substrate in a reactor forming carbon nanotubes by evaporation and decomposition, proximal to the etched metal substrate, of at least one carbon source in presence of at least one catalyst, wherein the at least one carbon source and the at least one catalyst are carried within the chemical vapour deposition reactor via a carrier gas depositing the formed carbon nanotubes on the etched metal substrate and processing the etched metal substrate at a temperature of 800oC for a pre-determined time period to obtain the metal base.
