Unified Denovo Multipurpose Analyzer

Abstract

Tooth movement is affected by various factors like magnitude, direction, and the duration of the forces applied; the direction of force plays the most pivotal part. Orthopedic appliances have long been used to apply extraoral traction forces to entirely limit or redirect the growth of the maxilla and mandible. Here, we present a very simple and efficient device. The multipurpose analyzer (MPA) is used to locate the center of resistance of maxilla and maxillary dentition, giving a more accurate direction of force vector in facemask and headgear cases. It is also used as chairside device clinically to measure facial heights, nasolabial angle, mentolabial angle, and mandibular plane (MP), as well as to measure cephalometrically MP, Frankfort horizontal (FH)–MP, palatal plane (PP)–MP, occlusal plane (OP), and MP during analysis.
