並列摘要


Extraction of the impacted mandibular third molar is one of the most common procedures in dental practice. There are various complications that may occur during or after tooth extraction, such as paraesthesia of inferior alevolar nerve or lingual nerve, mandibular/alveoalr bone fracture, and displacement of tooth to fascial space. Displacement of tooth into fascial space is a rare complication but could cause serious tissue damage to the patient. This article presents a case of CBCT-assisted removal of intra-operative displaced tooth, and discusses the possible causes and management principles of this condition.
