Comparison of rate of maxillary canine movement with or without modified corticotomy facilitated orthodontic treatment: A prospective clinical trial

Background and Objectives The average orthodontic treatment time for extraction therapy is 31 months. One of the main disadvantages of orthodontic treatment is time. Alveolar corticotomies have been used in conjunction with orthodontics to reduce the treatment time by increasing the rate of tooth movement. Concerns about the possible risks of corticotomy procedure have led to the modification of this technique. Germeç et al. reported a case treated by their modified corticotomy technique and noted reduced treatment time without any adverse effects on the periodontium and the vitality of teeth with their new conservative corticotomy technique. This study was undertaken to clinically evaluate the efficacy of the aforesaid technique. Materials and Methods A split-mouth study design was carried out to compare the rate of maxillary canine movement with and without modified corticotomy facilitated orthodontic treatment in 10 patients requiring maxillary first premolar extractions. The modified corticotomy procedure was performed on the maxillary arch unilaterally. The upper arch was immediately activated bilaterally after surgical procedure using equal orthodontic forces for retraction of the maxillary canines. The amount of tooth movement was recorded at an interval of every month till the completion of canine retraction. The rate of canine movement on experimental and control site was compared. The patients were followed for 6 months to check the occurrence of undesired effects such as root resorption, periodontal damage and loss of vitality of teeth on the experimental side. Results Higher mean velocity was observed in canines with modified corticotomy facilitated retraction compared to conventionally retracted canines; with the difference in mean velocity between the two groups was found to be clinically significant as well as statistically significant (P < 0.001). Interpretation and Conclusion The results suggested that modified corticotomy technique serves as an effective and safe way to accelerate orthodontic tooth movement, without adversely affecting the periodontium, root resorption, and the vitality of the teeth, as concluded by clinical and radiographic examination.

Abstract Background The micro-osteoperforation can be used to increase the rate of tooth movement, simplify complex orthodontic movements, and also help adjust the anchorage but there are conflicting reports on the effectiveness and adverse effects of this intervention. Objectives The aim of our systematic review and meta-analysis was to evaluate the effects of micro-osteoperforation on the rate of tooth movement in patients undergoing orthodontic treatment. Search methods A comprehensive search of MEDLINE, ISI web of science, EMBASE, Scopus, and CENTRAL online databases for studies measuring the effects of micro-osteoperforation on the rate of orthodontic tooth movement from inception to February 2019 was performed. Selection criteria Based on the PICO model, human studies which evaluated the effects of MOP on the rate of tooth movement in patients undergoing orthodontic treatment were selected for this review. Data collection and analysis The relevant data from the eligible studies were extracted using piloted custom extraction forms. The data were combined and analysed using inverse-variance random-effect meta-analysis and the mean difference was used for comparing the outcome measures. Results Six randomized clinical trials were finally included in this meta-analysis. The rate of canine retraction per month was significantly higher in the MOP group [mean difference (MD) = 0.45 mm, 95% CI = 0.17–0.74]. These results were similar with regard to different malocclusions, the jaw on which it was performed, and MOP methods. The patients did not report any significant differences in terms of pain severity levels after MOP. With regard to the adverse effects, one study reported higher amounts of root resorption among patients undergoing MOP. Conclusions The rate of tooth movement was increased after performing MOP but in at least one study higher root resorption was observed. Therefore, the use of MOP can be recommended after weighing the benefits and disadvantages this intervention can bring for each patient. Registration The protocol for this review was registered via crd.york.ac.uk/prospero with the ID CRD42019115499.

Demineralized Dentin

In today's era, there is an increased demand for orthodontic treatment, especially among young patients. The greatest concern amongst the patients undergoing orthodontic treatment is the increased treatment time. The fixed orthodontic treatment lasts up to 2 to 3 years which further increases the risk of complications associated with the treatment such as external root resorption, periodontal problems, and patient compliance [1]. Clinicians are constantly striving towards developing strategies to enhance the rate of orthodontic tooth movement and decreasing the treatment time. Numerous surgical modalities found to be highly effective in reducing the treatment time for orthodontic therapy include corticotomy, corticision, peizocision, periodontal distraction, dentoalveolar distraction etc. [2]. Wilcko et al. [3] introduced the combined approach corticotomy surgery with alveolar grafting in a technique referred to as Accelerated Osteogenic Orthodontics (AOO) and recently known as Periodontally accelerated osteogenic orthodontics (PAOO). Many studies dictated that PAOO is an extremely predictable, safe, effective technique. The risk of root resorption and the duration of treatment time is considerably reduced [3-5]. The present article focuses on accelerating the orthodontic tooth movement using a Demineralized dentin matrix (DDM) graft, alloplast and PRF membranes to reduce the treatment time and improves soft and hard tissue healing outcomes.

Nowadays, there is an increased tendency for researches to focus on accelerating methods for tooth movement due to the greater demand for adults for a shorter orthodontic treatment duration. Unfortunately, long orthodontic treatment time has many disadvantages like higher predisposition to caries, gingival recession, and root resorption. This increases the demand to increase tooth movement with the least possible disadvantages. Several modalities have been reported for accelerating the tooth movement. Thus, accelerating orthodontic tooth movement and the resulting shortening of the treatment time would be quite beneficial.

Abstract Background Techniques to accelerate tooth movement have been a topic of interest in orthodontics over the past decade. As orthodontic treatment time is linked to potential detrimental effects, such as increased decalcification, dental caries, root resorption, and gingival inflammation, the possibility of reducing treatment time in orthodontics may provide multiple benefits to the patient. Another reason for the surge in interest in accelerated tooth movement has been the increased interest in adult orthodontics. Review This review summarizes the different methods for surgical acceleration of orthodontic tooth movement. It also describes the advantages and limitations of these techniques, including guidance for future investigations. Conclusions Optimization of the described techniques is still required, but some of the techniques appear to offer the potential for accelerating orthodontic tooth movement and improving outcomes in well-selected cases.

The aim of this paper is to provide a review on the role of inflammation in orthodontically induced inflammatory root resorption (OIIRR) and accelerating orthodontic tooth movement (AOTM) in orthodontic treatment. Orthodontic tooth movement (OTM) is stimulated by remodeling of the periodontal ligament (PDL) and alveolar bone. These remodeling activities and tooth displacement are involved in the occurrence of an inflammatory process in the periodontium, in response to orthodontic forces. Inflammatory mediators such as prostaglandins (PGs), interleukins (Ils; IL-1, -6, -17), the tumor necrosis factor (TNF)-α superfamily, and receptor activator of nuclear factor (RANK)/RANK ligand (RANKL)/osteoprotegerin (OPG) are increased in the PDL during OTM. OIIRR is one of the accidental symptoms, and inflammatory mediators have been detected in resorbed roots, PDL, and alveolar bone exposed to heavy orthodontic force. Therefore, these inflammatory mediators are involved with the occurrence of OIIRR during orthodontic tooth movement. On the contrary, regional accelerating phenomenon (RAP) occurs after fractures and surgery such as osteotomies or bone grafting, and bone healing is accelerated by increasing osteoclasts and osteoblasts. Recently, tooth movement after surgical procedures such as corticotomy, corticision, piezocision, and micro-osteoperforation might be accelerated by RAP, which increases the bone metabolism. Therefore, inflammation may be involved in accelerated OTM (AOTM). The knowledge of inflammation during orthodontic treatment could be used in preventing OIIRR and AOTM.

Introduction: Root resorption is the loss of apical root tissue leading to the shortness of root which is often evident in orthodontic tooth movement. Proper management during orthodontic treatment however can minimize this undesirable outcome. The present article attempts to review the etiology of root resorption, methods of diagnosis, and strategies for prevention.Materials & Method: A scoping review was done with the purpose to carry out the narrative integration of the relevant evidences on root resorption and orthodontic treatment from the published literatures. The resulting papers were studied and reviewed thoroughly for the key explanation of root resorption in orthodontic patients. A total of 41 published research articles were reviewed.Discussion: According to the literatures root resorption is common iatrogenic outcome in orthodontic treatment. Biological, mechanical, and combined biological and mechanical factors result in external root resorption. Though most clinicians diagnose root resorption by conventional radiography, researches have clearly shown that CBCT is the promising tool. The clinicians need to counsel orthodontic patients and their parents that the root resorption might be a potential consequence of the treatment lasting for long time. In case of severity; it is essential to reassess the patient and minimize the underlying cause. It is necessary to understand the role of orthodontist in preventing root resorption

Introduction: The objective of the study was to assess the rate of canine retraction and secondary outcomes associated with conventional fixed orthodontic treatment (CFO) and CFO with micro-osteoperforation (CFO + MOP), that is, anchorage loss, root resorption, vitality of tooth, pain and discomfort level during the procedure. Methods: A total of 16 patients with Class II Division 1 malocclusion who required upper first premolar extraction with lower non-extraction/single incisor extraction were divided into the test group (MOP) and positive control group (CFO + MOP) for a split-mouth study. Both maxillary canines were retracted with nickel–titanium (NiTi) closed coil springs. Patients were reviewed after 24 hours, 7 days, 28 days, and 4, 8, and 16 weeks to assess the rate of tooth movement, anchorage loss, root resorption, vitality of tooth, pain and discomfort level. Results: There was a statistically significant difference in the rate of tooth movement between the CFO and CFO + MOP groups after the first 4 weeks ( P-value = .026), whereas no statistically significant difference was observed at 8, 12, and 16 weeks ( P-value = .33, .99, and .08, respectively). In the CFO group, there was no statistically significant difference in tooth movement between different time intervals ( P-value > .05). There was no significant difference in root resorption between the groups. The pain level was higher in the MOP group in the first 24 hours ( P-value < .05) after the procedure. Later on, the difference in pain level between the groups was not significant ( P-value > .05). The vitality of retracted canines in both groups was healthy. Conclusion: The study recommends that the CFO + MOP procedure has substantial potential to be used as an adjunct to the routine mechanotherapy for faster tooth movement, as it may reduce the treatment time by half in the first 4 weeks after the MOP procedure. There are no potential differences in anchorage loss, tipping, vitality, and apical and lateral root resorption between the CFO and CFO + MOP groups. This trial was registered at Clinical Trial Registry, India.

Background and aim. Orthodontic tooth movement (OTM) is a process whereby the application of a force induces bone resorption on the pressure side and bone apposition on the tension side of the lamina dura. However, only limited data are available on the in vivo behavior of the periodontal tissues. The aim of this study was to assess the changes of periodontal tissues, induced by the orthodontic canine retraction, using 40 MHz ultrasonography.Methods. Ultrasonographic evaluation of periodontal tissues was conducted in 5 patients with indication for orthodontic treatment. The upper first premolars were extracted bilaterally due to severe crowding, and the canines were distalized using elastomeric chain with a net force of 100 cN. Ultrasonographic scans (US scans) were performed before, during and after retraction, in three distinct areas of the canines buccal surface: mesial, middle and distal. The reference point was the bracket, which appeared hyperechoic on the US scan. Four different dimensions were obtained: D1 (depth of the sulcus), D2 (thickness of the gingiva), D3 (length of the supracrestal fibers), D4 (width of periodontal space).Results. An increase of D1 was observed in all three areas of the periodontium, during orthodontic treatment. D3 was strongly correlated before and immediately after force delivery only for the mesial area (r=0.828, p<0.05). In total, 228 variables were statistically analyzed using Pearson’s correlation coefficients, in order to demonstrate the relationship between periodontal findings during orthodontic tooth movement.Conclusions. High-resolution ultrasonography has the capability to obviate changes in periodontal ligament space and free gingiva during orthodontic tooth movement.

The purpose of this review is to identifyknown and controversial relevant aspects of the role of laser application and biochemical markersduring accelerating orthodontic tooth movement. Biochemical markers that mediate acceleration oforthodontic tooth movement were identified in this review, and also was found that this accelerationof dental movement is possible due to the bone functional properties and its ability to deposition(mediated by osteoblasts) and bone resorption (mediated by osteoclasts). For each of these processesexist biochemical markers that can be measured in serum or urine. Bone formation markers arecollagen and non-collagenous proteins while pyridinoline and deoxypyridinoline are resorptionmarkers. There are numerous mechanisms to accelerate tooth movement described in the literature;surgical as corticotomy, insights intramedullary piezocision and surgery first, pharmacological asprostaglandins and D vitamin, and physical as pulsatile stimuli and laser therapy. The purpose ofall of them is to accelerate the process and to have shorter orthodontic treatment. The lasertherapy has been reported as a safe and effective alternative to accelerate tooth movement and theireffects on cell populations involved in bone metabolism and pain have been evaluated in animalstudies and in humans, showing good results to reduce the total orthodontic treatment time andhaving less pain sensation after placement of the arches used in the different stages oftreatment.We concluded that nowadays there is no randomized controlled clinical trials published toevaluate the application of these biochemical markers in the process of acceleration of bonemetabolism during orthodontic treatment with the application of low intensity laser (GaAlAs)considered as an effective tool to increase the speed of tooth movement and to reduce pain afteractivation of orthodontic arches.
