When corticotomy is performed along with aligner treatment, the frequency of appliance changes is every three to four days. Alveolar corticotomy may easily be associated with skel- etal anchorage devices. Temporary anchorage devices are used to increase anchorage, while corticotomies are used to reduce anchorage. 6. Proper patient selection for corticotomy is essential Alveolar corticotomy is not for every patient, and it is not feasible to use it on a routine basis in clinical prac- tice. The main indication is in clinical cases with complex OTMs. Open-flap surgery is indicated in impacted teeth, surgery-first procedures with extractions, orthognathic surgery with major postoperative OTMs, complex space closures with reduced supporting tissue, and maxillary expansion in periodontally compromised cases. MOP is indicated in treatments with aligners, complex OTMs without periodontal problems and patients with financial limitations. ortho 1 2018 25 Fig. 17 ing: in some cases, appliances are placed a week after the surgery, while in others (for example, when distal- ising maxillary molars or repositioning impacted teeth) several months before corticotomy. The enhanced tooth movement deriving from the RAP reaction is obtained when needed. The major dif-
