Corticotomy

BACKGROUND: We described the use of the technique of L-shaped corticotomy with bone flap sliding to treat chronic osteomyelitis of the tibia in eight patients and presented the preliminary results. METHODS: L-shaped corticotomy with bone flap sliding was performed in eight patients between 2007 and 2014. All patients had chronic tibial osteomyelitis involving the anterior tibial cortex with intact and healthy posterior cortex. The size of bone defects following sequestrectomy and radical debridement was 8...

BACKGROUND: Piezocision-assisted orthodontics (PAO) is considered one of the modern techniques aiming at reducing the treatment time and overcoming some limitations of orthodontic treatment. The use of piezocision as an adjunct in the treatment of posterior crossbite is limited, so additional research in this area is required. AIM: To three-dimensionally compare the skeletal and dental effects produced by piezocision-assisted rapid maxillary expansion (PARME) and conventional rapid maxillary expansion (RME) using cone beam computed tomography (CBCT)...

INTRODUCTION: To quantify the rate of tooth movement in two corticotomy protocols in an experimental model in rats through macroscopic and radiographic analysis. METHODS: The animals were divided into three groups: orthodontic movement (CO), orthodontic movement plus corticotomy surgery (G2), and orthodontic movement and corticotomy surgery with decorticalization (G3).The euthanasia occurred in 7 and 14 days. The data were statistically analyzed (p < 0.05)...

Purpose: Procedures such as Periodontally Accelerated Osteogenic Orthodontics (PAOO) support the use of osteotomy to aid tooth movement and rapid distraction of the periodontal ligament by utilizing tissue engineering principles with periodontal regenerative surgery. The aim of this study was to evaluate and compare the amount of tooth movement and the associated changes in buccal bone morphology between corticotomy and flapless Micro-Osteoperforation (MOP) assisted orthodontic treatment...

BACKGROUND: We successfully treated a 37-year-old male who had skeletal open bite with severe amelogenesis imperfecta (AI) with orthodontics, compression osteogenesis, and prosthodontics. CASE PRESENTATION: The patient was diagnosed with severe anterior open bite caused by severe AI. Corticotomy was performed on both buccal and palatal sides of the molar regions, and anchor plates were placed onto the bilateral zygomatic buttress and the center of the hard palate...

OBJECTIVE: The aim of this study was to evaluate a flapless surgical technique as an alternative to traditional alveolar corticotomy used to accelerate orthodontic tooth movement (OTM). METHODS: To induce OTM in Wistar rats, 40 cN of orthodontic force were applied to the maxillary left first molars. Forty rats were distributed into control groups (CG1, CG3, CG7 and CG14) and experimental groups (n= 5), in which alveolar perforations were made using a spear-shaped guide bur (EG1, EG3, EG7, EG14)...

Infected nonunion and malunion of tibial plateau are rare injuries with no standardized protocols for treatment. This study assessed the outcome of chronic infected intra-articular proximal tibial fractures with and without metaphyseal bone loss managed with the Ilizarov ring fixator. A series of six patients of intra-articular infected nonunion of the tibial plateau and two patients with malunited plateau with metaphyseal nonunion were treated in a tertiary care hospital. Three of these eight patients had a metaphyseal bone loss or bone gap after debridement and underwent internal transport with distal corticotomy to obtain the bone length...

BACKGROUND AND AIM: In view of few large prospective studies available on the role of preoperative diffusion tensor imaging(DTI), and the potential of DTI in revealing tumour and white matter tracts relationship, we studied the role of 'preoperative DTI' in planning safe surgical corridor, predicting the neurological and surgical outcome and tumour characterization in supratentorial intra-axial brain tumours. METHODOLOGY: We included 128 cases. Preoperative neurological status and tumour volume was assessed...

Corticotomy was introduced as a surgical procedure to shorten orthodontic treatment time. Corticotomy removes the cortical bone that strongly resists orthodontic force in the jaw and keeps the marrow bone to maintain blood circulation and continuity of bone tissues to reduce risk of necrosis and facilitate tooth movement. In the 21st century, the concept of regional acceleratory phenomenon was introduced and the development of the skeletal anchorage system using screw and plate enabled application of orthopedic force beyond conventional orthodontic force, so corticotomy has been applied to more cases...

Autograft bone graft harvest is an important surgical technique in the armamentarium of the orthopaedic surgeon. The iliac crest can provide a robust amount of bone graft, but using it carries a risk of complications including neurologic injury, gait disturbance, sensory dysesthesia, and ilium fracture. We present a surgical technical involving harvest of cancellous bone graft from the anterior iliac crest that minimizes the complication profile associated with tricortical bone graft harvest. It should be noted that there are differences between the outcomes of anterior and posterior crest harvests...

Severe facial asymmetry in adults with hemifacial microsomia or other types of mandibular hypoplasia is challenging to treat with simultaneous maxillomandibular distraction osteogenesis using an external distractor combined with intermaxillary fixation (IMF). Using an external distractor also produces significant distress for patients for at least 8 weeks. Furthermore, mandibular-driven distraction tends to elongate the midface, with difficulty positioning of the center of the maxilla in the center of the face and horizontalization of the occlusal plane...

Objective: This study was performed to investigate the rate of tooth movement and histological characteristics of extraction sockets those were subjected to corticotomy. Methods: A split-mouth randomized controlled trial experiment was designed. Thirty-two adult, male Wistar rats were divided into 2 groups: healing extraction socket (H) and recent extraction socket (R); these groups were randomly classified into 4 subgroups (0/7/21/60 days). The first maxillary molar was extracted on 1 side and 2 months were allowed for complete bone healing; then, the corresponding molar was extracted on the other side and surgical intervention was performed at the mid-alveolar point of the first maxillary molar...

Clinical evidence has suggested that surgical corticotomy of the alveolar bone can accelerate local orthodontic tooth movement (OTM), but the underlying cell and molecular mechanisms remain largely unclear. The present study examined the role of macrophages played in corticotomy-assisted OTM. Orthodontic nickel-titanium springs were applied to the left maxillary first molars of rats or mice to induce OTM with or without corticotomy. Corticotomy enhanced OTM distance by accelerating movement through induction of local osteoclastogenesis and macrophage infiltration during OTM...

PURPOSE: To study the effect of corticotomy in assisting space closure in cases whose alveolar ridge atrophy was obvious after extraction. METHODS: Twenty two cases whose canine's distal movement<0.2mm/m were selected, 12 accepted corticotomy and the other 12 were selected as the control group. All the spaces were closed with sliding mechanics under the help of microscrews. SPSS 13.0 software package was used for statistical analysis. RESULTS: All the spaces were closed...

BACKGROUND: Piezocision is a localised piezoelectric alveolar decortication involving minimally invasive corticotomies to accelerate orthodontic treatments. The objective of this proof-of-concept was to describe an innovative protocol combining selective piezocision with minimally invasive bone regeneration to reduce the risk of buccal tissue dehiscences often observed in orthodontic treatments. This proof-of-concept initial report aimed at investigating whether this new surgical concept is relevant...

Nonunion is a devastating complication of tibial fractures with a debilitating effect. Several studies reporting tibial nonunions in adults are available; however, the reports on infected nonunions in children are scarce. The purpose of this study was to evaluate the results of treating paediatric infected tibial nonunion using Ilizarov fixator without radical resection. MATERIALS AND METHODS: The study included 36 cases with infected nonunion of the tibia with 31 males and 5 females, and an average age of 11...

BACKGROUND: The aim of the study was to assess the effect of corticotomy-assisted orthodontic treatment on soft tissue clinical parameters in patients with malocclusions with transverse maxillary deficiency. METHODS: The study included 20 generally healthy adult individuals with malocclusion, who underwent a corticotomy-assisted orthodontic treatment in maxilla. During the corticotomy performed after full-thickness flap elevation, only the buccal cortical plate was cut with the use of OTS-7, OTS7-4, OTS7-3 ultrasound tips of the piezosurgery device (Mectron s...

INTRODUCTION: Exogenous Nel-like molecule type 1 (NELL1) represents a potentially attractive clinical treatment option in the orthodontic and other settings because of its osteoinductive and vasculogenic properties. AIMS: To explore effects of NELL1on corticotomy-assisted tooth movement and osteogenesis in a rat model. METHODS: Thirty Sprague-Dawley rats were divided into 6 groups: Control, Sham, Tooth movement only, Vehicle, NELL1-LD (low-dose NELL), NELL1-HD (high-dose NELL)...

Periodontally accelerated osteogenic orthodontics (PAOO) is a clinical procedure that incorporates selective corticotomy, particulate grafting, and application of optimal orthodontic forces. It reduces treatment time, increases stability of teeth, and prevents relapse of orthodontic tooth movement (OTM). The present case report highlights the technique and principles of PAOO for rapid OTM.

Process of the mesialization of molars in the lower jaw is long-time, moreover the molars are not frequently bodily translation. Conduction of the corticotomy reduce to regional acceleration phenomen that permit to accelerate the tooth movement avoiding negative inclination. PURPOSE: To improve the effectiveness of the treatment using piezocorticotomy and miniscrew anchorage approach in cases of third and second molar mesialization when first molar is missing. MATERIAL AND METHODS: 24 patients (10 men/14 women) aged 25-40 years with a fixed vestibular braces and the absence of molars on the lower jaw...
