Corticotomy

When the duration of orthodontic treatment is shortened, the patient may have a number of benefits, including an increase in the number of dental cavities, root resorption, and gingival irritation, all of which are associated to a higher degree of decalcification. In addition to drugs, magnets, and other therapies, they include surgical methods (corticotomies, piezosurgery), mechanical/physical stimulation techniques (vibration, lasers), and other forms of therapy. These methods, each of which has been validated by extensive research, have been shown to reduce treatment times...

BACKGROUND AND OBJECTIVES: Both invasive and minimally invasive surgical methods have recently gained popularity in accelerating orthodontic tooth movement. Traditional corticotomy (TC) was one of the first effective invasive surgical techniques in shortening orthodontic treatment time, whereas the flapless cortico-alveolar perforations (FCAPs) technique is a modern minimally invasive method that has recently shown good results in different types of orthodontic tooth movement. Therefore, this study aimed to compare the effectiveness of TC versus FCAPs in maxillary canine retraction when treating Class II division 1 malocclusion patients...

OBJECTIVE: This study aimed to assess the levels of pain, discomfort, and functional impairment associated with the en-masse retraction of the upper anterior teeth when treating Class II division 1 malocclusion patients using traditional corticotomy or flapless corticotomy. In addition, an assessment of patients' satisfaction with the selected surgical intervention was undertaken at one-month post-operatively. MATERIALS AND METHODS: The study sample comprised 40 patients with Class II division 1 malocclusion, randomly assigned to either the traditional corticotomy group (n=20) or the flapless corticotomy group (n=20)...

Numerous surgical techniques have been developed as effective means to facilitate orthodontic treatment, although they may cause significant postoperative discomfort. Piezocision was established as a flapless and minimally invasive technique to accelerate orthodontic tooth movement by combining small vertical incisions and piezoelectric corticotomies. Computed tomography has been combined with the piezocision technique to fabricate computer-aided design and computer-aided manufacturing (CAD/CAM) surgical guides to prevent iatrogenic damage...

BACKGROUND AND AIM: Various methods to accelerate the orthodontic tooth movement have been used, among which corticotomy is considered to be the most common one. The suggested reasoning for such acceleration was the regional acceleratory phenomenon (RAP). Since the RAP is a property of both the hard and soft tissues, we designed a soft tissue flap procedure to compare the effects with the conventional corticotomy procedure. A split-mouth study was conducted where the two procedures were assessed in a single participant...

BACKGROUND/PURPOSE: Alveolar bone fenestration and dehiscence is common in untreated patients and potentially harmful. This study was to evaluate the effect of augmented corticotomy (AC) on the prevention and treatment of alveolar bone defects in skeletal class III high-angle patients during presurgical orthodontic treatment (POT). MATERIALS AND METHODS: Fifty patients with skeletal Class III high-angle malocclusion were enrolled, of whom 25 patients (G1) underwent traditional POT and 25 patients (G2) received AC during POT...

Intramedullary reaming has been proven to be a safe and effective method for enhancing the union rates of long bone fractures. However, there is a risk of equipment failure, which can lead to severe complications. We present two cases of reamer failure during femoral nailing which illustrate the rare occurrence of intraoperative instrument failure. Our report also underscores the importance of routinely inspecting reaming equipment and provides technical insights to reduce the risk of failure.

OBJECTIVES: The objective of the study is to test whether the local injection of i-PRF may affect osteoblast, blood vessels and new bone formation in surgically expanded mid palatal suture using maxillary skeletal expander. MATERIALS AND METHODS: Eighteen adult male local breed dogs were divided randomly into three groups: group I (control), includes the expansion with maxillary skeletal expander that was done without corticotomy and i-PRF. Group II, involves the expansion that was done with mid palatal corticotomy but without i-PRF injection...

The management of horizontally fully edentulous atrophic ridges could be a common problem in dental implantology. This case report describes an alternative modified two-stage presplitting technique. The patient was referred for an implant-supported rehabilitation of edentulous inferior mandible. Considering that the mean available bone was about 3 mm in width on CBCT scans, at the first stage, four linear corticotomies were performed using a piezoelectric surgical device. At the second stage (after 4 weeks), the bone expansion was performed and four implants were placed in the interforaminal area...

UNLABELLED: Surgical management in those with moderate-to-severe airway obstruction includes tongue-lip adhesion, tracheostomy, and/or mandibular distraction osteogenesis. This article describes a transfacial two-pin external device technique for mandibular distraction osteogenesis, utilizing minimal dissection. METHODS: The first percutaneous pin is transcutaneously placed just inferior to the sigmoid notch parallel to the interpupillary line. The pin is then advanced through the pterygoid musculature at the base of the pterygoid plates, toward the contralateral ramus, and exits the skin...

OBJECTIVE: To compare the post-treatment periodontal status of the palatally impacted canines and their adjacent teeth treated by an accelerated minimally-invasive corticotomy-assisted method versus the conventional traction method. MATERIAL AND METHODS: A parallel-group two-arm randomized controlled trial was conducted on patients with palatally or mid-alveolar unilateral impacted canines. Participants were randomly selected and allocated to receive the conventional treatment (CT) with a closed surgical approach, or accelerated treatment (CAT)...

Orthodontics has considerably increased the use of technology combined with surgery as a tool to improve dental movements in terms of predictability, acceleration of movement, and fewer side effects. To achieve these goals miniscrews and corticotomy were introduced. The digital workflow permits an increase in the accuracy of surgical and orthodontic setups. The tool that transfers the information is the CAD/CAM ( Computer-Aided Design/ Computer-Aided Manufacturing) template. The aim of this review is to illustrate the use of computer-guided surgery in orthodontics regarding miniscrews and piezocision...

The present article explores the benefits of combining periodontally accelerated osteogenic orthodontics (PAOO) with Invisalign for optimal orthodontic treatment outcomes. PAOO is an interdisciplinary dental technique that minimizes complications and accelerates tooth movement while enhancing various orthodontic treatments. In conjunction with Invisalign, PAOO provides a discreet and comfortable solution for patients seeking to improve their smile. The study presents two challenging cases successfully treated using this combined approach, emphasizing the technique's potential to reduce treatment times and improve orthodontic outcomes...

Aim One of the major difficulties in orthodontic treatment is the lengthy course of therapy, particularly in situations involving extractions. Hence, various methods for accelerating tooth movement rate had been devised. Flapless corticotomy is one of those methods. This study aimed to evaluate the effects of flapless laser corticotomy (FLC) compared to the conventional retraction (CR) method on the rate of canine retraction. Methods A split-mouth, randomized controlled trial included 56 canines from 14 patients (12 females and two males) with a mean age of 20...

Different temporary anchorage device (TAD)-assisted rapid palatal expanders may be used to treat malocclusions involving the transverse dimension and, in many instances, prevent more complex situations in the future. Each style of expander has advantages and disadvantages. The acrylic type of TAD-supported palate lateral wall expander is a reliable and cost-effective appliance for expansion treatment in adolescents and young adults (ie, aged 13 to 21). In comparison, other palatal expander designs are more suitable for older patients...

BACKGROUND: No randomized controlled trial (RCT) has studied the accuracy of surgical guides used in terms of orthodontic treatment acceleration. Therefore the aim of this trial was to assess computer-guided piezocision-based orthodontic. MATERIALS AND METHODS: Thirty-two patients with severely crowded upper anterior teeth were enrolled and randomly allocated to either the experimental group (ExpG) or the control one. Subjects of the ExpG received three-dimensional (3D) guided piezoelectric corticotomies on the buccal alveolar bone of the anterior region...

PURPOSE: This study investigated the impact of local corticotomies on mesenchymal stem cells (MSCs) and pro-regenerative growth factors contained in bone marrow aspirate concentrate(BMAC). METHODS: Five domestic pigs (Sus Scrofa), 4-5 months of age, either sex, were included. Each pig underwent operations for creation of two 1cm-long corticotomies at one randomly chosen tibia (as experimental), with the other tibia left intact (as control). At postoperative day-14, bone marrow was aspirated from both tibiae and processed into BMAC samples, from which MSCs and plasmas were separated...

INTRODUCTION: Intraoperative ultrasound (IOUS) may aid the resection of space-occupying brain lesions, though technical limits may hinder its reliability. METHODS: IOUS (MyLabTwice® , Esaote, Italy) with a microconvex probe was utilized in 45 consecutive cases of children with supratentorial space-occupying lesions aiming to localize the lesion (pre-IOUS) and evaluate the extent of resection (EOR, post-IOUS). Technical limits were carefully assessed, and strategies to enhance the reliability of real-time imaging were accordingly proposed...

BACKGROUND: Presurgical three-dimensional (3D) reconstructions allow spatial localization of cerebral lesions and their relationship with adjacent anatomical structures for optimal surgical resolution. The purpose of the present article is to present a method of virtual preoperative planning aiming to enhance 3D comprehension of neurosurgical pathologies using free DICOM image viewers. CASE DESCRIPTION: We describe the virtual presurgical planning of a 61-year-old female presenting a cerebral tumor...

Introduction Dental crowding is one of the most common types of malocclusions. It can be treated with or without extraction, depending on the severity of the crowding. Extraction-based orthodontic treatments are the preferred treatment option in cases of severe crowding, but they take longer than non-extraction cases. Objective This study aimed to evaluate the dentoalveolar changes following the orthodontic treatment of severely crowded maxillary anterior teeth in adults using self-ligating brackets alone or combined with flapless piezocision...
