LOSA MUNOZ, Pedro Manuel; BURGUENO GARCIA, Miguel  and  GOMEZ GARCIA, Elena. Maxillary distraction with internal devices in cleft patients: Virtual planing and transference of dates to surgical field. Rev Esp Cirug Oral y Maxilofac [online]. 2017, vol.39, n.2, pp.80-84. ISSN 2173-9161.


Maxillary internal distractors have not been widely used since the accurate positioning is challenging. This is because a small deviation in the positioning results in a great deviation in the final position of the distracted maxilla. Computer assisted surgery is a powerful tool to reach accurate results. The authors report a protocol for internal distractor positioning as well as a new object for transferring dates from virtual planning to surgical field.

Material and method:

Virtual planning was performed to plan the maxillary advance in 2 cleft patients. A wafer with 2 lateral attachments was used to transfer the vector of distraction from virtual planning to surgical field.


Satisfactory result was achieved in both patients.


This virtual planning protocol as well as the CAD/CAM objet to transfer dates from computer to surgical field are useful in order to achieve a suitable final position of the maxilla. These tools facilitate the positioning of internal distractors, leaving the use of external distractors for advancement greater than 12 mm.
