Nonextraction treatment of severe crowding with the aid of corticotomy-assisted orthodontics.

Aljhani AS, Zawawi KH - Case Rep Dent (2012)

Bottom Line: The total treatment time was 8 months with no adverse effects observed at the end of active treatment.The addition of the decortication procedure to the conventional orthodontic therapy decreased the duration of treatment significantly.Successful alignment of both arches with ideal overbite and overjet as well as adequate occlusion was achieved.

ABSTRACT
THIS PAPER ILLUSTRATES THE COMBINED NONEXTRACTION ORTHODONTIC TREATMENT WITH THE CORTICOTOMY TECHNIQUE IN AN ADULT PATIENT (AGE: 25 years and 3 months) with severely crowded arches to accelerate tooth movement and shorten the treatment time. Both her upper lateral incisors were congenitally absent and both upper central incisors' roots were short. Initial fixed orthodontic appliances (bidimensional) were bonded and one week later buccal and lingual corticotomy with alveolar augmentation procedure in the maxilla and mandible was performed. Orthodontic activation to level and align and unravel the crowding was performed every two weeks. The total treatment time was 8 months with no adverse effects observed at the end of active treatment. The addition of the decortication procedure to the conventional orthodontic therapy decreased the duration of treatment significantly. Successful alignment of both arches with ideal overbite and overjet as well as adequate occlusion was achieved.

fig5: Maxillary and mandibular corticotomy of the buccal side.

Mentions: Corticotomy technique as described by Wilcko [12] was performed by a periodontist. Briefly, after administering the proper anesthetic dose, a full thickness flap was reflected sharply both facially and lingually around all erupted teeth, in both arches, from the first molar to the first molar (Figure 5). Each flap was released with a sulcular incision and with papillary preservation technique when possible. The lingual interdental papilla between the maxillary central incisors was not reflected and no vertical releasing incisions were used. Cuts in the alveolus that penetrate the entire thickness of the cortical plate and penetrate just barely into the medullary bone were performed both buccally and lingually around all the teeth in both arches. Vertical decortication cuts were made between the roots of the teeth and they were stopped 2-3 mm shy of the alveolar crest. Horizontal scalloped corticotomy cuts were used to connect the vertical cuts along with perforations in the cortical plate. Bone grafting mixture OraGraft demineralized cortical particulate (LifeNet Health, Inc., Virginia Beach, VA, USA) was then applied to the activated cortical plates. Flaps were repositioned to their pre-surgical positions and sutured with interrupted loop sutures. Nonresorbable sutures (Gore-tex, CV-5, RT-16, from W. L. Gore & Associates, Inc., Medical Products Division, Flagstaff, AZ, USA) were used and the sutures were removed after 14 days from the procedure. The patient was kept under antibiotic for 10 days following the surgery.
