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...

Segment Yes Yes Design 1: Review of Orthodontic Aligner Treatment Plan The orthodontic aligner treatment plan under review presents several critical concerns regarding its design and execution. Below are the key observations and critiques based on the treatment's mechanics and outcomes. 1. Simultaneous and Unsynchronized Movements The treatment plan exhibits **simultaneous and unsynergistic movements**. Specifically, the anterior teeth are moved first, followed by space closure, and then the mesialization of the posterior teeth. This approach neglects the importance of **staging and phases**, leading to a lack of sequential mesialization. The enmasse retraction strategy employed has drastic effects on anchorage, resulting in a **dumping effect** that compromises the overall treatment efficacy. Additionally, the rotations of ...

  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...

  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

  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...
