“…They used rat models and applied an orthodontic force of 25 g to observe the effects of flap and multiple micro-osteoperforation surgery, inducing a more severe injury with a lighter force; therefore, a lag phase might not have appeared. Our result is consistent with that of Mostafa et al, 19 who reported that the experimental and control groups exhibited a similar orthodontic tooth movement pattern: initial, lag, and postlag phase. However, Mostafa et al used 400 g of force, an unusually heavy force that might have induced a lag phase in their study on dogs.…”

Objective: To investigate the effects of flapless micro-osteoperforation and corticision on the rate of orthodontic tooth movement in rats. Materials and Methods: Forty-five 8-week-old male Sprague-Dawley rats were divided into the following groups: micro-osteoperforation and orthodontic force (MOP + F), corticision and orthodontic force (C + F), and orthodontic force only (F, control). The left maxillary first molars were pulled forward with a force of 50 g. Flapless surgical interventions were conducted in the MOP + F and C + F groups. The total duration of the experiment was 6 weeks. Alveolar bone density and the number of osteoclasts were evaluated using microcomputed tomography and histologic examination, respectively. Results: The tooth movement distance was significantly higher in both experimental groups than in the control group. Bone density and bone mineral density decreased in the MOP + F and C + F groups. The number of osteoclasts in the MOP + F and C + F groups was significantly higher than in the control group F. Conclusion: The two minimally invasive flapless surgical interventions increased bone remodeling and osteoclast activity and induced faster orthodontic tooth movement for at least 2 weeks in rats. No differences were observed between the outcome of flapless micro-osteoperforation and corticision in the rats. (Angle Orthod. 2016;86:558-564.)

“…However, due to the postoperative discomfort and risk of complications, [7][8][9] Kim et al 9 in 2009 introduced corticision as a surgery complementary to orthodontic treatment to accelerate tooth movement via regional acceleration 9,10 with minimal surgical intervention. Although the effectiveness of corticotomies 1,3,6,7 and corticisions 9,10 have been documented, no studies have compared these techniques. Therefore, the present study was conducted to comparatively evaluate the tooth movement rate and histological a Graduate Student, Graduate Program in Orthodontics, School of Health and Biosciences, Pontifícia Universidade Católica do Paraná , Curitiba, Brazil.…”

“…2,3 The goal of this strategy is to create bone blocks containing one or more teeth that could be moved more quickly than individual teeth. 1 Studies involving clinical [3][4][5][6][7] and histological 1,[6][7][8] evaluation have demonstrated that corticotomy is effective. However, due to the postoperative discomfort and risk of complications, [7][8][9] Kim et al 9 in 2009 introduced corticision as a surgery complementary to orthodontic treatment to accelerate tooth movement via regional acceleration 9,10 with minimal surgical intervention.…”

Objective: To compare the histological responses in corticotomy-and corticision-assisted tooth movement. Materials and Methods: Ninety Wistar rats were divided into three groups: C (control-tooth movement only), CT (tooth movement þ corticotomy), and CI (tooth movement þ corticision). Surgeries were performed on the vestibular and lingual cortical bone of the maxillary first molar. Tooth movement was carried out with nickel-titanium closed coil springs having a force of 30 g. The rats were sacrificed at 3, 14, and 28 days. To evaluate the number of osteoclasts and amount of root resorption, a tartrate-resistant acid phosphatase stain was used. Hematoxylin and eosin staining was performed for areas of hyalinization, and the organic bone matrix was stained with picrosirius. Results: The CT group showed a greater number of osteoclasts than did the C group on day 3 (P , .05). At the same time point, the CT and CI groups showed a delayed onset of organic bone matrix remodeling and a lower incidence of root resorption than did the C group (P , .05). There were also fewer hyalinization areas in the CI group than in the C group on day 3 (P , .05). Conclusions: Corticotomy effectively increased bone resorption during the early stages of tooth movement, but this increase was not observed for corticision. The surgical procedures did not accelerate organic bone matrix remodeling. Corticotomies and corticisions decreased the risk of root resorption only during the early stages of movement. Corticision reduced the level of hyalinization, while corticotomy did not. (Angle Orthod. 2017;87:118-124)

“…29 In a recent study comparing corticotomy-facilitated OTM versus standard technique in dogs with mini screws as anchor units, corticotomy doubled the rate of OTM and histologic analysis evidenced more active and extensive bone remodelling for corticotomy, suggesting acceleration in OTM associated with corticotomy is due to increased bone turnover and relies on a regional acceleratory phenomenon (RAP). 30 The regional acceleratory phenomenon (RAP), recognized by Frost 31,32 , defines a complex physiologic healing process involving accelerated bone turnover and decreased regional bone density in response to surgical wounding of osseous tissue. As a local response to noxious stimuli in sites of decortication extending to the marrow, RAP is an intensified bone response and rapid remodelling process featuring increase in osteclasticosteoblastic activity and in levels of local and systemic inflammation markers.…”

Periodontologlar ve ortodontistler arasındaki sinerji, her iki disiplini de ilgilendiren kombine terapilerin klinik sonuçlarını geliştirmek için önemli fırsatlar yaratır. YÖNTEMLER: Bu iki uzmanlık alanının işbirliği, ortodontik tedaviye bağlı olarak periodontal sağlığın daha iyi düzeye ulaşmasına ve buna karşılık doğru periodontal idame ile ortodontik terapinin başarısının artmasına yol açar. Periodontoloji ve ortodontinin beraberliği konvansiyonel tedavilerin yanı sıra, 'periodontal olarak hızlandırılmış osteojenik ortodonti™ (PAHOO)' gibi yeni gelişen tedavi alternatifleri açısından da önemli rol oynar. BULGULAR: PAHOO™ tekniği, 'ortodontik tedavi ile kombine edilmiş alveolar kortikotomiye ilave olarak kemik ogmentasyonuna yönelik gretfleme' olarak tanımlanır. Sağlıklı dokulardaki deminerilizasyon-reminerilizasyon süreçlerinin çabuk ve geçici doğasına dayalı destekleyici ve umut veren bir teknik olarak PAHOO™, alveolar kortikotomi ile labial ve palatinal/lingual yüzeylerin kemik greftlemesini takiben ortodontik kuvvet uygulanmasından oluşur. Azalmış ortodontik tedavi süresi, artmış kemik hacmi ve post-ortodontik stabilite PAHOO™ tekniğinin en önemli avantajları olarak sıralanmaktadır. Kortikotomi-yardımlı ortodontinin tarihsel kökenleri 1800'lü yıllara kadar dayansa da, literatürde az sayıda hayvan deneyi ve klinik olgu sunumu izlenmekte ve bu tekniğin uzun dönem başarısını doğrulamak için kontrollü, prospektif ve histolojik araştırmalara ihtiyaç duyulmaktadır. SONUÇ: Bu bağlamda derlememizin amacı PAHOO™ tekniğini tarihsel gelişim, biyolojik esaslar ve klinik düşünceler çerçevesinde gözden geçirmektir.
