Guided bone regeneration-assisted orthodontic treatment for closing the space of missing central incisors

doi:10.7518/hxkq.2021.04.017

Abstract

Abstract:

Long-term missing teeth can lead to alveolar bone loss in the edentulous area. Guided bone regeneration (GBR) is a bone augmentation method. It is widely used in clinical practice and broadens the indications of orthodontic treatment to a certain extent. This article reports a case of an adult patient with edentulous space in the maxillary central incisor, which was successfully closed through orthodontic treatment combined with GBR. This study will provide a re-ference for future clinical work.

Key words: guided bone regeneration, incisor missing, space closure
