Review Article:
Autotransplantation in combination with orthodontic treatment
Racha Hariri, Emad Eddin M. Alzoubi
J Orthodont Sci
2019, 8:11 (8 August 2019)
DOI

INTRODUCTION:
Autotransplantation is a surgical method in which a tooth is repositioned within the same patient. It can be described as a controlled reimplantation of an extracted tooth into a new, surgically prepared socket. The key to success of this treatment is the preservation and regeneration of the periodontal ligament. It is an underutilized technique which, if conducted with a multidisciplinary team, can be an ideal treatment option for patients with failing or missing teeth.
OBJECTIVES:
The detailed clinical procedures, indications for this technique, and the factors affecting its success are discussed.

Review Article:
Alar width changes due to surgically-assisted rapid palatal expansion: A meta-analysis
Kevin C Lee, Michael Perrino
J Orthodont Sci
2017, 6:115 (5 October 2017)
DOI

A major objective of orthognatic surgery is the aesthetic outcome. Treatments only correcting for dentoskeletal deformities are not sufficient for optimal facial results because undesirable soft tissue changes may accompany skeletal manipulations. The primary objective of this study was to investigate alar base width (ABW) changes a minimum of 6 months following surgically-assisted rapid palatal expansion (SARPE). The following electronic databases and citation indices were searched: PubMed, Cochrane Library, Scopus, Web of Science, Embase, and Virtual Health Library. The search included articles published until September 2015 without language restriction. The intervention was SARPE with maxillary vestibular incision from first molar to contralateral first molar, a modified LeFort I osteotomy with or without pterygomaxillary disjunction, and a V-Y closure. The primary outcome was the unstandardized mean difference between pre and postoperative ABW. A random effects meta-analysis was performed to combine study results, and included studies that were assessed for statistical heterogeneity using a Chi-square test for independence. The results of this meta-analysis (
N
= 41) showed a significant + 1.74 mm, 95% CI [0.14, 3.34] ABW increase in patients submitted to SARPE. There was no statistical heterogeneity among included studies (
χ
2
=
0.03; df = 2;
P
= 0.98). ABW increases were observed despite including cinched patients in the analysis. None of the three included studies were completely free of bias. The most prominent flaws were measurement bias, limited sample size, and patient recruitment.

Obstructive sleep apnea is an exciting area for orthodontists to be involved. The level of awareness of sleep apnea and related health issues is growing rapidly. The demand of integrating sleep into the orthodontic practice shortly will be driven by the need of the societies as some of our patients will be shortly coming into our offices aware of sleep apnea. However, with our busy clinical orthodontic practice, the need of condense short review become more demanding. Therefore, this review will try to summarize the clinical and orthodontic observation in the diagnoses of adult obstructive sleep apnea with clinical application in orthodontic practice.

Review Article:
An overview of surgery-first approach: Recent advances in orthognathic surgery
Vipul Kumar Sharma, Kirti Yadav, Pradeep Tandon
J Orthodont Sci
2015, 4:9 (19 January 2015)
DOI

PMID
:25657986
The disadvantages of having orthodontic interventions both before and after orthognathic surgery include a long treatment time of 7-47 months and temporary worsening of facial appearance. Nowadays, the concept of surgery-first, followed by orthodontic treatment is applied to orthognathic surgery cases in different orthodontic centers in the world. This concept and technique is called "surgery-first-orthognathic-approach" or "surgery-first approach" (SFA) rigid fixation (skeletal anchorage system) of the bony segments and regional acceleratory phenomenon were keys to broad implementation of the SFA. This article is intended to provide an overview of SFA including indications, general and specific guidelines, different protocol variations, success rate and potential problems.

Review Article:
Canine retraction: A systematic review of different methods used
Rohit S Kulshrestha, Ragni Tandon, Pratik Chandra
J Orthodont Sci
2015, 4:1 (19 January 2015)
DOI

Canine retraction is a very important step in treatment of patients with crowding, or first premolar extraction cases. In severe crowding cases until, the canines have been distilized to relive the crowding, space to correctly align the incisors will not be available. Correct positioning of the canines after retraction is of great importance for the function, stability, and esthetics. The aim of this systematic review was to examine, in an evidence-based way, which kinds of canine retraction methods/techniques are most effective and which have the least side effects. A literature survey was performed by applying the Medline Database (Entrez PubMed) and Science Direct database covering the period from 1985 to 2014, to find out efficient ways to accomplish canine retraction. Randomized controlled trials (RCTs), prospective and retrospective controlled studies, and clinical trials were included. Two reviewers selected and extracted the data independently and assessed the quality of the retrieved studies. The search strategy resulted in 324 articles, of which 22 met the inclusion criteria. Due to the vast heterogeneity in study methods, the scientific evidence was too weak to evaluate retraction efficiency during space closure. The data so far reviewed proved that elastomeric power chains, elastic threads, magnets, NiTi coil springs, corticotomies, distraction osteogenesis, and laser therapy, all are able to provide optimum rate of tooth movements. All the methods were nearly similar to each other for retraction of canines Most of the techniques lead to anchorage loss in various amounts depending on the methods used. Most of the studies had serious problems with small sample size, confounding factors, lack of method error analysis, and no blinding in measurements. To obtain reliable scientific evidence, controlled RCT's with sufficient sample sizes are needed to determine which method/technique is the most effective in the respective retraction situation. Further studies should also consider patient acceptance and cost analysis as well as implants and minor surgeries for canine retraction.

Review Article:
Can orthodontic relapse be blamed on the temporomandibular joint?
Larry M Wolford
J Orthodont Sci
2014, 3:95 (18 October 2014)
DOI
:10.4103/2278-0203.143227
There are many temporomandibular joint (TMJ) conditions that can cause orthodontic treatment instability and relapse. These conditions are often associated with dentofacial deformities, malocclusion, TMJ pain, headaches, myofascial pain, TMJ and jaw functional impairment, ear symptoms, etc., Many of these TMJ conditions can cause progressive and continuous changes in the occlusion and jaw relationships. Patients with these conditions may benefit from corrective orthodontic and surgical intervention. The difficulty for many clinicians may lie in identifying the presence of a TMJ condition, diagnosing the specific TMJ pathology, and selecting the proper treatment for that condition. This paper will discuss the most common TMJ pathologies that can adversely affect orthodontic stability and outcomes as well as present the treatment considerations to correct the specific TMJ conditions and associated jaw deformities to provide stable and predictable treatment results.

Amelogenesis imperfecta and anterior open bite: Etiological, classification, clinical and management interrelationships
Xanthippi Sofia Alachioti, Eleni Dimopoulou, Anatoli Vlasakidou, Athanasios E Athanasiou
J Orthodont Sci
2014, 3:1 (19 February 2014)
DOI

PMID
:24987656
Although amelogenesis imperfecta is not a common dental pathological condition, its etiological, classification, clinical and management aspects have been addressed extensively in the scientific literature. Of special clinical consideration is the frequent co-existence of amelogenesis imperfecta with the anterior open bite. This paper provides an updated review on amelogenesis imperfecta as well as anterior open bite, in general, and documents the association of these two separate entities, in particular. Diagnosis and treatment of amelogenesis imperfecta patients presenting also with anterior open bite require a lengthy, comprehensive and multidisciplinary approach, which should aim to successfully address all dental, occlusal, developmental, skeletal and soft tissue problems associated with these two serious clinical conditions.

Review Article:
Iatrogenic possibilities of orthodontic treatment and modalities of prevention
Nazeer Ahmed Meeran
J Orthodont Sci
2013, 2:73 (9 October 2013)
PMID
:24987646
The benefits of orthodontic treatment are numerous and in most cases, the benefits outweigh the possible disadvantages. Orthodontic treatment can play an important role in enhancing esthetics, function, and self-esteem in patients. However, it carries with it the risks of enamel demineralization, tissue damage, root resorption, open gingival embrasures in the form of triangular spaces, allergic reactions to nickel, and treatment failure in the form of relapse. These potential complications are easily avoidable by undertaking certain precautions and timely interventions by both the orthodontist and the patient. The orthodontist must ensure that the patient is aware of the associated risks and stress the importance of the patient's role in preventing these untoward outcomes. The decision whether to proceed with the orthodontic treatment is essentially a risk-benefit analysis, where the perceived benefits of commencing treatment outweigh the potential risks. This article provides an overview of the iatrogenic possibilities of orthodontic treatment and the role of the patient as well as the orthodontist in preventing the associated risks.

Review Article:
Allergy and orthodontics
Sunitha Chakravarthi, Sridevi Padmanabhan, Arun B Chitharanjan
J Orthodont Sci
2012, 1:83 (11 January 2013)
DOI
:10.4103/2278-0203.105871
PMID
:24987632
The aim of this paper is to review the current literature on allergy in orthodontics and to identify the predisposing factors and the implications of the allergic reaction in the management of patients during orthodontic treatment. A computerized literature search was conducted in PubMed for articles published on allergy in relation to orthodontics. The MeSH term used was allergy and orthodontics. Allergic response to alloys in orthodontics, particularly nickel, has been extensively studied and several case reports of nickel-induced contact dermatitis have been documented. Current evidence suggests that the most common allergic reaction reported in orthodontics is related to nickel in orthodontic appliances and allergic response is more common in women due to a previous sensitizing exposure from nickel in jewellery. Studies have implicated allergy in the etiology of hypo-dontia. It has also been considered as a high-risk factor for development of extensive root resorption during the course of orthodontic treatment. This review discusses the relationship and implications of allergy in orthodontics.

Review Article:
Biological response at the cellular level within the periodontal ligament on application of orthodontic force - An update
Nazeer Ahmed Meeran
J Orthodont Sci
2012, 1:2 (17 April 2012)
DOI
:10.4103/2278-0203.94769
PMID
:24987618
Orthodontic force elicits a biological response in the tissues surrounding the teeth, resulting in remodeling of the periodontal ligament and the alveolar bone. The force-induced tissue strain result in reorganization of both cellular and extracellular matrix, besides producing changes in the local vascularity. This in turn leads to the synthesis and release of various neurotransmitters, arachidonic acid, growth factors, metabolites, cytokines, colony-stimulating factors, and enzymes like cathepsin K, matrix metalloproteinases, and aspartate aminotransferase. Despite the availability of many studies in the orthodontic and related scientific literature, a concise integration of all data is still lacking. Such a consolidation of the rapidly accumulating scientific information should help in understanding the biological processes that underlie the phenomenon of tooth movement in response to mechanical loading. Therefore, the aim of this review was to describe the biological processes taking place at the molecular level on application of orthodontic force and to provide an update of the current literature.
