Computer Assisted Retrieval of Accidentally Displaced Wisdom Teeth

An article titled “Use of Computer-Assisted Navigation in the Retrieval of Accidentally Displaced Third Molars,” appears in the 2016 Journal of Oral and Maxilofacial Surgery, written by Yi Guo and et al., vol. 74, pp. 889-894. The article describes using a computer to retrieve accidentally displaced mandibular third molars. A total of 12 patients in the study successfully had their roots retrieved. They all healed successfully without complications. In rare cases when performing wisdom teeth surgery, a tooth or a tooth root can be displaced. When they are displaced into difficult to access areas surgery retrieving the displaced molars should be performed by conventional methods which include extending the original operative exposure or planning a new operative approach and then finding and removing the tooth. This surgery can cause severe tissue injury or complications. The paper discusses computer-assisted navigation in the retrieval of displaced mandibular third molars and to evaluate the effectiveness of this method. The criterion for using this technique of computer-assisted navigation involved teeth or tooth fragments that were displaced into difficult-to-access areas (sublingual space, pterygomandibular space, lateral pharyngeal space, submandibular space, and lateral cervical space). To localize the displaced mandibular third molar or root fragment computed tomographic […]
