Corticotomy facilitated orthodontics: Review of a technique

Abstract

Corticotomy found to be effective in accelerating orthodontic treatment. The most important factors in the success of this technique is proper case selection and careful surgical and orthodontic treatment. Corticotomy facilitated orthodontics advocated for comprehensive fixed orthodontic appliances in conjunction with full thickness flaps and labial and lingual corticotomies around teeth to be moved. Bone graft should be applied directly over the bone cuts and the flap sutured in place. Tooth movement should be initiated two weeks after the surgery, and every two weeks thereafter by activation of the orthodontic appliance. Orthodontic treatment time with this technique will be reduced to one-third the time of conventional orthodontics. Alveolar augmentation of labial and lingual cortical plates were used in an effort to enhance and strengthen the periodontium, reasoning that the addition of bone to alveolar housing of the teeth, using modern bone grafting techniques, ensures root coverage as the dental arch expanded. Corticotomy facilitated orthodontics is promising procedure but only few cases were reported in the literature. Controlled clinical and histological studies are needed to understand the biology of tooth movement with this procedure, the effect on teeth and bone, post-retention stability, measuring the volume of mature bone formation, and determining the status of the periodontium and roots after treatment.

Three-dimensional evaluation of upper anterior alveolar bone dehiscence after incisor retraction and intrusion in adult patients with bimaxillary protrusion malocclusion

“…For example, minor tooth movement and bone quantity limitation should be considered, force magnitude direction should be controlled, detriment of periodontal injury should be evaluated by regular radiographic examination, and ridge expansion osteotomy should be emphasized as an alternative way of decreasing the anatomical limitation of palatal portion (Kim S.J. et al, 2009;AlGhamdi, 2010). With these effective procedures, we might be able to lower the incidence of alveolar bone dehiscence, accomplishing our goal of maintaining the health, function, and aesthetics of the periodontium in the orthodontic treatment.…”

“…The tissue formation rate was estimated to be two to ten times faster than normal regeneration process around the field of corticotomy area. 3 This change in bone turn-over rate can also affect the interaction between the miniscrew implants and the bone, however detailed studies are needed before blaming the bone physiology and at this time there is no study to support such an interaction. Although the exact reason for the loss of mini-screws in our case is difficult to define, it is advisable to take any necessary precautions to hold the mini-screws in place until the space is fully closed.…”

Application of surgical periodontics for accelerated orthodontic correction of class ll division l malocclusion with skeletal discrepancy

“…6 Now the patients are in constant per suit of selecting simplified minimally invasive surgical treatment protocols with less recovery time. 7 The treatment of skeletal discrepancies are less often conducted with the application of orthognathic surgical options because of the reluctance of patients, even though they are still now considered as the optimal treatment planning. These are some of the reasons for developing classified surgical techniques to facilitate orthodontic treatment without compromising periodontal bone support.…”
