Orthodontic aligners treatment: Designing Problems

-
  Design 1 1. Segmentation Problems : The treatment plan exhibited significant segmentation issues. 2. Alignment & Leveling Woes : There were noticeable problems with the alignment and leveling of the upper anterior teeth. This was particularly evident in both the occlusal and submento-vertex views, indicating a need for better planning and execution. 3. Inadequate Arch Shape : The arch shape deviated from the ideal U-shape, which could negatively impact the patient's bite and overall function. This aspect requires immediate attention to ensure proper occlusion. 4. Attachment Issues : The positioning and thickness of attachments were inadequate, particularly on the upper left canine, where the doctor specifically requested no attachment placement. This could lead to ineffective tooth movement and discomfort for the patient. 5. Class III Elastic Mismanagement : The use of Class III elastics on the left side for over three months was a significant oversight. This prolonged applic...

Decalcification And Caries Associated With Orthodontic Treatment

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 ti...

Orthodontic Iatrogenic Damage To The Periodontium

  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 localiz...

Thermoformed vs 3D Printed Aligners

  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 esthet...

  if you are intersted in this article please follow for more readings https://myorthodonticsblogg.blogspot.com/        👈🏻 Class II Division 2 (definition) : Acc. To Angle’s Classification It is when the buccal groove of the 1 st Mandibular molar occludes distal to mesio-buccal cusp of 1 st maxillary molar with retroclination of maxillary central incisors. Acc. To British Standards classification (Incisor relationship) The lower incisors edgs occlude posteriorly to the   cingulum plateau of the upper incisors &   the lower centrals are retruded (due to lack of stops) Sub-types Type A : Maxillary centrals and      laterals are retroclined. Type B : Maxillary Laterals overlapping the retroclined centrals . Type C : Maxillary centrals and laterals areretroclined and are overlapped by max. canines.   Criteria Extra Oral features : - Shape of head : Brachycephalic - Facial Profile : Convex...

Arch wire sequencing in Orthdontics

  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 a...

The Concept of the Straight Wire Appliance in Orthodontics

Image
  if you are intersted in this article please follow for more readings https://myorthodonticsblogg.blogspot.com/        👈🏻 The occlusion research (study of the non-orthodontic normals) had been launched to get a better understanding of occlusion and how it was related to the buccolabial surfaces of the crowns. There was no intention originally to produce a new appliance, but the need for one became evident.       The arising concept was to Pre-program suitable treatment into the appliance and therefore the SWA was developed. The built-in features of the SWA guide the teeth along direct vector lines, eliminating jiggling, round-tripping and other excessive movements. Andrews’s philosophy of treatment     A bracket type for each tooth type:       Since within any dentition, teeth differ from each other, therefore, each tooth would require its own bracket.    Measurements of the non-orthodo...
