Pendulum appliance의 생역학과 임상적용

Abstract

Molar distalization was frequently used to gain space in non-extraction cases because it produced better results than arch expansion or proclination of anterior teeth in periodontic aspects and stability. Pendulum appliance first-introduced by Hilgers in 1992, reduced anchor part movements during molar distalization by using palatal vault which contacts Nance button as additional anchorage. Many other modified pendulum appliance has been developed for controlling intermolar width, axial inclination and vertical movement of molars as well as molar distalization and therefore if it is used in proper patients, it produces uniform results irrespective of compliance of patients. Indications and biomechanical considerations of pendulum appliance and dental and skeletal changes by pendulum appliance will be discussed and 2 cases that unilateral and bilateral molar distalization was performed in growing patients will be presented.
