Space Regainers : A review of literature

Abstract

Premature loss of primary teeth, particularly second molars, often leads to significant arch space reduction, causing eruption disturbances such as impactions or ectopic eruptions of permanent teeth. In paediatric dentistry, space regaining appliances are essential tools to re-establish lost arch space and guide the proper eruption of permanent successors. This review explores the comprehensive range of fixed and removable space regainers, their biomechanical principles, clinical applications and limitations, providing guidelines for their use.
