Clear Aligner

Orthodontics has witnessed not only an exponential rise in demand from adult patients but accompanying this, the emergence of alternate aesthetic treatment options to the more traditional fixed labial appliance. The concept of using clear aligners as a means of achieving tooth movement has increased in popularity among both patients and clinicians alike. However, the question over best research evidence as to their clinical effectiveness to treat a range of malocclusion traits remains elusive and controversial among the profession. In an attempt to offer the profession some clear guidance, The Angle Society of Europe reviewed and discussed the current published evidence (2005–2018) on their clinical use, during the annual meeting in January 2020, to help formulate a consensus viewpoint on the clinical applications.

Abstract Introduction: In the literature, no consensus has been reached about orthodontic treatment time. Similarly, the determining factors of the latter have not yet been completely elucidated. Objective: The aim of the present article was to deepen the discussion on the major factors influencing orthodontic treatment time, as well as to present some strategies that have proven effective in controlling and shortening it. Method: Based on evidences found in the literature, the method focussed in providing the basis for clinical decision-making. Conclusions: Treatment time varies according to the type of malocclusion and treatment options. Orthodontist’s influence, patient’s characteristics and compliance are all decisive in determining treatment time, while the effects provided by orthodontic appliances and methods used to speed tooth movement up seem little effective.

This chapter focuses on what information should be provided to patients about the evidence base supporting the clinical effectiveness of psychotherapy. In particular, the authors consider whether research on the relative efficacy of different forms of psychotherapy should be provided to patients, as well as whether patients should be provided with information on the relative importance of common factors versus specific factors as the causal agents of clinical improvement. After a critical review and discussion of the relatively few scholarly papers that have previously addressed this question, the authors conclude that patients should be provided with an honest, transparent, and impartial summary of the evidence related to their treatment options including information about the common factors. The authors offer this conclusion even while acknowledging that considerable controversy persists about how to interpret the psychotherapy research evidence base. Finally, the authors strongly support continued research into these questions, especially given the relatively limited scholarly attention they have received to date.

Fixed Appliances

Orthodontic treatment is usually conducted by applying forces to certain teeth to move them into a targeted position. Orthodontic wires have been reported to be the primary modalities used in fixed-appliances-based orthodontic treatment to induce favorable tooth movement events. Accordingly, acquiring adequate knowledge about these approaches' clinical applications and biochemical behavior is essential when planning for a successful orthodontic treatment. Orthodontic wires are widely used and are mainly composed of composites, polymers, alloys and metals. Accordingly, the physical properties and clinical application of orthodontic wires vary based on their composition. In this context, it was recommended that achieving favorable outcomes of orthodontic treatment obliges clinicians to decide the best orthodontic wire and treatment plan based on the chemical properties and related clinical applications of each wire. Therefore, wires that tend to produce increasing stiffness gradually are generally used. However, it should be noted that no ideal wire exists. Therefore, favoring the application of a wire over the other should be based on the intended outcomes and stage of the treatment process.

Clear Aligner

Clear aligner technology has become the preferred choice of orthodontic treatment for malocclusions for most adult patients due to their esthetic appeal and comfortability. However, limitations exist for aligner technology, such as corrections involving complex force systems. Composite attachments on the tooth surface are intended to enable active control of tooth movements. However, unintended tooth movements still occur. In this study, we present an effective attachment design of an attachment that can efficiently induce tooth movement by comparing and analyzing the movement and rotation of teeth between a general attachment and an overhanging attachment. The 3D finite element modes were constructed from CBCT data and used to analyze the distal displacement of the central incisor using 0.5- and 0.75-mm-thick aligners without an attachment, and with general and overhanging attachments. The results show that the aligner with the overhanging attachment can effectively reduce crown tipping and prevent axial rotation for an intended distal displacement of the central incisor. In all models, an aligner with or without attachments was not capable of preventing the lingual inclination of the tooth.

Orthodontic Retention

Retention is normally required after active orthodontic tooth movement in order to maintain tooth position and minimize the effects of age-related changes to the dentition. The aim of this article is to define stability, retention and relapse with reference to the literature and to review the evidence with regards to clinical effectiveness of different types of fixed and removable retainers and wear regimens, with emphasis on systematic reviews and Randomized Controlled Trials (RCTs). Furthermore, to discuss the general dental practitioner's role and responsibility in managing patients after active orthodontic treatment. CPD/Clinical Relevance: It is common practice for orthodontists to review patients for one year after active orthodontic treatment. Beyond this period, monitoring of the patient's long-term retention is often carried out in general dental practice. This paper provides an overview of orthodontic retention, including retainer types, wear regimens and a discussion of the common problems associated with retainers and advice on management.

Clear Aligner

Malocclusion is defined as irregularity of the teeth or a mal-relationship of the dental arches beyond the range of what is accepted as normal occlusion. Maloccluded teeth can cause psychological problems that are related to impaired dentofacial esthetics. Malocclusion may also cause serious problems related to oral health. This is a multifactorial defect caused by factors such as environment, lifestyle, health, genetics, socio-economic status etc. Clear aligners are orthodontic therapeutic options which are preferred for the correction of maloccluded teeth. The main aim of the study was to find out the awareness of the patients towards the preference of clear aligners as orthodontic treatment options. A University based setting was conducted. A sample size of hundred patients was taken for the survey. The survey was done by distributing an online questionnaire through Google forms consisting of 11 questions and circulated among the participants. The participants comprise both male and female patients. To eliminate bias, a randomized sampling method was used. The data was collected over a period of one week. All the 11 questions of the survey were close ended questions. Chi square test was applied to find the association between the parameters and the level of significance. This study shows the patients have a moderate understanding of clear aligners and their acceptance of it as an orthodontic treatment option.

Morphological Modification

There are several options for replacing a missing maxillary central incisor in orthodontic treatment. Substituting a missing central incisor with the contralateral one can be a useful approach to reduce the number of teeth that require extraction during the treatment. Normal tooth movement across an ossified midpalatal suture (MPS) has only been observed in an animal experiment. Herein, we describe the treatment of a 26-year-old woman who had lost multiple teeth on one side, including the maxillary right central incisor, which required extraction due to endodontic failure. The maxillary left central incisor was moved into the position of the maxillary right central incisor. All other left maxillary teeth were moved mesially to close the space. After completion of orthodontic treatment, acrylic build-up was performed on the maxillary left lateral incisor, which underwent morphological modification to replicate the morphology of a maxillary right incisor. The patient was pleased with the treatment outcome. Cone-beam computed tomography provided evidence of tooth movement across the MPS. Although the movement of the tooth across the MPS is feasible, the treatment plan should also take other treatment options into consideration.

Aesthetics is a major factor in Orthodontic treatment and it is a primary concern among patients seeking orthodontic treatment. To meet the growing aesthetic desire for an alternative to traditional braces, researchers have created a variety of alternatives, including ceramic or composite braces, lingual orthodontics, and transparent aligners. Clear aligner therapy is a treatment that consists of a set of clear dental appliances that are custom-made to fit the contour of a patient's teeth. Clear Aligners are an alternative to traditional braces that are used to guide teeth into appropriate alignment. Clear aligners, like braces, utilise a progressive force to regulate tooth movement, but without the need of metal wires or brackets.
