     if you are intersted in this article please follow for more readings https://myorthodonticsblogg.blogspot.com/ In this Article many questions have been answered .. 1- What are the advantages of using orthodontic aligners over traditional braces? 2-How do orthodontic offices incorporate aligners into their treatment plans? 3- what is shape-memory sheet (ClearX)? 4-Are there any limitations or drawbacks to using aligners for orthodontic treatment? Orthodontic aligners have several advantages over traditional braces, including: 1. Aesthetics: Aligners are virtually invisible, making them a popular choice for adults and teenagers who are self-conscious about their appearance. Unlike traditional braces, which use metal brackets and wires, aligners are made of clear plastic and are custom-fitted to the patient's teeth. 2. Comfort: Aligners are made of smooth, comfortable plastic that does not irritate the gums or cheeks. Unlike traditional braces, which can cause discomfort an

if you are intersted in this article please follow for more readings https://myorthodonticsblogg.blogspot.com/     👈🏻 Enamel demineralization is a common negative consequence of orthodontic treatment in the absence of appropriate oral hygiene maintenance. It is the loss of calcified tooth substance due to the attack by acidic-by-products of plaque metabolism. An early recognition is sentient to prevent permanent damage. Occurrences during active treatment necessitate a shortened treatment plan or in severe cases; early termination of treatment. The increase in food stagnation and increase in the retentive sites of bacteria lead to a change in the microflora (low Ph environment). Decalcification may occur within one month due to : Prolonged accumulation of plaque next to the bracket . White Spot Lesions caused by the decalcification process can be distinguished from the developmental hypocalcified lesions on the basis of location, shape, and dimensional stability with time.

  if you are intersted in this article please follow for more readings https://myorthodonticsblogg.blogspot.com/     👈🏻 1. Periodontal disease and orthodontic treatment : Periodontal disease includes gingivitis, alveolar bone loss (periodontitis), and loss of attached gingival support. The periodontal reaction toward orthodontic appliances depends on multiple factors, such as: - Host resistance - The presence of systemic conditions - The amount and composition of dental plaque. - Lifestyle factors, including smoking, can also compromise periodontal support and the negative effects of uncontrolled diabetes on periodontal support.  Bacteria present in dental plaque are the primary causative agent of periodontal disease . Orthodontic treatment with fixed appliances is known to induce an increase in the volume of dental plaque. However, fixed orthodontic appliances cause a shift in the type of bacteria . Therefore, fixed orthodontic treatment may result in localized gingivitis, which rar

  if you are intersted in this article please follow for more readings https://myorthodonticsblogg.blogspot.com/     👈🏻 Jindal et al. 2019 presented a successfully 3D printed 0.75 mm thick clear aligner using Dental Long Term (LT) clear resin and compared its mechanical and geometrical properties to a conventionally manufactured thermoformed Duran clear dental aligners.  Dental Long Term (LT) clear resin and compared its mechanical and geometrical  properties to a conventionally manufactured thermoformed Duran clear dental aligners .  It  was suggested that 3D printed resin-cured clear dental aligners are more suitable because they have better geometric accuracy and mechanical resistance. In early 2018, EnvisionTEC Inc. announced launch of E-Ortholign, a new material for the direct 3D printing of clear thermoformed aligners . This clear resin is marketed as biocompatible, stable, flexible and strong material for the direct 3D printing of esthetic retainers, Direct 3D printing of cle

  if you are intersted in this article please follow for more readings https://myorthodonticsblogg.blogspot.com/       👈🏻 Arch sequencing depends on : 1-   Archwire Types 2-   Archwire Functions 3-   Archwire Sequencing according to cases (where different situations requires sequences ) 4-   Pain associated with Archwire placement and activation  INTRODUCTION        A successful orthodontic therapy depends not only on manual skills and knowledge of treatment steps but also on knowledge and choice of materials used. One of the major components of fixed orthodontic therapy is the choice of wires. Orthodontic wires are defined as devices comprising a wire conforming to the alveolar or dental arch, which is used as an anchorage for correcting irregularities in the position of teeth . Therefore, the aim of the this assignment   was to focus on the differences in the features of wires as well as their working sequence according to the treatment plan.   1-   Archwire Types:
