暂无简介。

•Patients are awaiting orthognatic surgical treatment, namely: Le Fort I osteotomy (upper jaw) as part of their treatment plan.;• A dorsal down graft of the maxilla, or upper jaw, must be part of the planned translocation. ;• Patients are susceptible to 3D virtual planning of their surgical intervention, e.g. their mouth opening must be sufficient for gathering a dental imprint of both upper and lower jaw at the same time. This will not require a large opening, however, when suffering from trismus it can be problematic to gather the double imprint. At least 40mm of mouth opening is usually required to gather the dentition imprint information.;• The patient is at least 18 years of age. Completion of physical growth is a routine criterion for orthognatic surgery.

•Patient does not agree to randomised application of osteosynthesis method;• Patient is, for any reason, not able to undergo the 3D virtual planning procedure, including double dentition imprints, pre-operative CBCT scanning and virtual planning of translations. An example could be the inability to complete the dental imprint of both upper and lower jaw, or inadequate scanning of the patient. These examples will, if applicable, come up during the preparation appointment with the patient, and therefore not delay the patients trajectory.;• Pregnancy, which is a general contraindication for orthognatic surgery.;• Allergy to titanium, which would mean a general exclusion for orthognatic surgery
