Abstract:

BACKGROUND: A classical orthognathic scheme for mandibular prognathism includes preoperative cephalometric analysis, acquiring modulus, facebow transfer, model surgery, making occlusion plate. This process is cumbersome, complex, and prone to have bias. Moreover, orthognathic effects are difficult to be predicted, which is a major difficulty in doctor-patient communication.
OBJECTIVE: To summarize and analyze the use of three-dimensional scanning techniques in the treatment and diagnosis of mandibular prognathism, including principle, application and relative merits, thus providing reference for applying to the clinic.
METHODS: Papers addressing the use of three-dimensional scanning techniques in the diagnosis and treatment of mandibular prognathism were retrieved by computer in Wanfang and PubMed databases with the key words of “three-dimensional scanning, class III, orthognathic, mandibular prognathism” in Chinese and English, respectively. A total of 48 papers were included for review.
RESULTS AND CONCLUSION: Compared with the traditional technology, the three-dimensional scanning technology has high accuracy and efficiency in the diagnosis and treatment of mandibular prognathism, and can directly capture the 3D geometry of objects for modeling, collection and measurement of biological data, which provides a reliable monitoring method for postoperative assessment and follow-up. Compared with the CT, the three-dimensional scanning technology cannot show the internal structure and separate hard and soft tissues, which should be reasonably chosen according to practical data.
