Corticotomy, orthodontic microsurgery in patient with reduced periodontium. Report of a clinical case.

Resumen

Treatment of a patient afflicted with periodontitis, malcocclusion, periapical pathosis and reduced periodontium often requires a combination of several surgical techniques as well as inter-disciplinary treatments  aimed at achieving optimum results. Objective. Presentation of corticotomy technique in patient with reduced periodontium aimed at orthodontic treatment success in lesser time and with minimum alteration of  periodontal tissues. Methodology: 42 year old female patient suffering from localized moderate chronic periodontitis. Orthodontic diagnosis emitted pointed out  meso-facial skeletal Class III. Surgery undertook to elevate a flap, with papilla preservation, to eliminate periapical lesion in tooth number 12, and bone filling of the defect. GTR was performed on tooth number 23. Corticotomy  of the upper arch was undertaken with electrical scalpel. Results. Six weeks after surgery, clinical changes were observed in the horizontal and vertical overbite, no other clinical or radiographic changes were observed. Seven months after surgery the patient presented stable occlusion, and achieved functional and aesthetic results. Conclusions: Corticotomy represents an alternative for adult patients suffering from tooth malposition and reduced periodontium.
