Study population: Patient in need of orthodontic treatment and presenting one or more teeth stiff

Brief summary: Codify the treatment of teeth by stiff Corticotomy technique. Evaluate the duration of treatment and tooth movement.

Detailed description: Codify the treatment of teeth by stiff Corticotomy technique. Evaluate the duration of treatment and tooth movement.

During treatment the teeth by stiff Corticotomy, millimeter measurements are performed on a cohort of patients with this pathology. These measures take place during normal clinical phases and on all media such as, plaster models, photographs and radiological examinations performed at the beginning, during and at the end of treatment.

Eligibility criteria: Inclusion Criteria:

* Patient in need of orthodontic treatment and presenting one or more teeth stiff
* Can meet the requirement of orthodontic treatment (attendance, quality of brushing)
* Showing no indication against General Surgery

Exclusion Criteria:

* A patient against indication for orthodontic treatment : Root resorption of teeth adjacent to stiff teeth, Dental anchoring Deficiency by multiple agenesis or agenesis of the adjacent teeth to teeth stiff, Loss of periodontal support or active periodontal disease
* A patient against indication to treatment with Corticotomy : General Pathology against indicating surgery, Proximity root with no possibility of improvement orthodontic preparation
* Inability to maintain a good level of oral hygiene and good cooperation.

Primary outcomes:
measure: Change of the distal view of the tooth mesial to the stiff corner of the adjacent tooth
timeFrame: Before orthodontic preparation, At the end of the orthodontic preparation on the day of surgery, Then 7 days, 15 days, 21 days, 30 days, 45 days, 60 days from the date of Surgery, at the end of the treatment of ankylosed teeth
Secondary outcomes:
measure: Change of the mesial angle of the ankylosed tooth to the distal (or mesial) angle of the adjacent tooth
timeFrame: Before orthodontic preparation, At the end of the orthodontic preparation on the day of surgery, Then 7 days, 15 days, 21 days, 30 days, 45 days, 60 days from the date of Surgery, at the end of the treatment of ankylosed teeth
measure: Change of the incisal edge of ankylosed tooth to the Incisal edge of lower incisor, In occlusion
timeFrame: Before orthodontic preparation, At the end of the orthodontic preparation on the day of surgery, Then 7 days, 15 days, 21 days, 30 days, 45 days, 60 days from the date of Surgery, at the end of the treatment of ankylosed teeth
measure: Change of free gingival margin of the ankylosed tooth to the gingival margin of the distal adjacent tooth
timeFrame: Before orthodontic preparation, At the end of the orthodontic preparation on the day of surgery, Then 7 days, 15 days, 21 days, 30 days, 45 days, 60 days from the date of Surgery, at the end of the treatment of ankylosed teeth
measure: Change of free gingival margin of the ankylosed tooth to the gingival margin of the mesial adjacent tooth
timeFrame: Before orthodontic preparation, At the end of the orthodontic preparation on the day of surgery, Then 7 days, 15 days, 21 days, 30 days, 45 days, 60 days from the date of Surgery, at the end of the treatment of ankylosed teeth
