Introduction: 30 percent of craniofacial abnormalities on patients have vertical maxillary excess. This condition is usually accompanied with great teeth exposure, gummy smile and mandible clock rotation. The following technique is an alternative of a conventional osteotomy Le fort I and is based on the turnover of hard and soft tissues through a corticotomy with light and continues forces by Niti coils and microimplants.

Materials and methods: The selection criterion of the patients was that all individuals had a dental class I and vertical maxillary excess between 5 and 7 mm. To determine these parameters, all patients had extra and intra oral photos, X ray films.

After the initial selection of patients, they were treated by an orthodontist who did the initial aligning and leveling of teeth prior to the surgery. The procedure was done under sedation at an ambulatory care unit.

Results and conclusions: Because of the simplicity and low mortality rate of this procedure, it can be done with sedation and at an ambulatory care unit. The success rate of this technique has been successful on all cases treated. Furthermore, it has several advantages compared to conventional osteotomies such as, reduced operatory time, general anesthesia is not necessary needed, less bleeding and therefore the postoperative discomfort is quite reduced as well as the high medical cost.
