Plastic Bracket Testing Instruments

Plastic brackets are made of unfilled polycarbonate (PCB). They show many problems, such as tie-wing fracture and slot distortion due to lack of strength and stiffness, increased slot roughness, staining, and an odour due to oral fluids adsorption. To overcome these problems, efforts were undertaken to improve mechanical strength by employing new polymers with increased stiffness incorporation of smooth metallic slots and polymer reinforcement with glass fibres. The present study aimed to evaluate some properties of modern plastic brackets including composition, morphology, slot roughness, hardness, and bond strength with enamel. Plastic orthodontic brackets are an aesthetic option for patients who require orthodontic treatment with braces. These brackets are made from specialized high strength plastics and they are shaded to match the patient's teeth to make them almost invisible. These brackets feature smooth, moulded edges and are easy to place making them a great option when comfort and esthetics are desired in an orthodontic case. Manufacturers ensure that the quality of Plastic brackets must of the best quality which can be tested using Plastic Bracket Testing Instruments.
