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...

Are there any potential risks or complications associated with maxillary arch expansion that are discussed in the literature ? (summary )

-
Image
  The article "Effects of Maxillary Arch Expansion: A Systematic Review of Systematic Reviews" provides a comprehensive overview of the craniofacial effects of maxillary expansion. The authors conducted a systematic review of systematic reviews and meta-analyses to summarize and critically appraise the available evidence concerning maxillary expansion treatment effects. The authors identified 16 systematic reviews and meta-analyses that met their inclusion criteria. These studies evaluated the effects of maxillary expansion on various outcomes, including the transverse dimension of the maxillary and mandibular arches, mid-palatal suture, facial soft tissue, root resorption, periodontal health, circummaxillary sutures, nasal airway, TMJ, obstructive sleep apnea, and more. Overall, the authors found that maxillary expansion is an effective treatment for correcting transverse maxillary deficiency in both children and adults. The treatment can lead to significant increases in a...

Deep overbite malocclusion: Analysis of the underlying components (summary)

-
Image
  This study aimed to analyze the various skeletal and dental components of deep bite malocclusion and their contributions to the problem. The researchers conducted a thorough analysis of all deep bite components to lead to more individualized treatment planning and mechanotherapy. The study found that an exaggerated curve of Spee and a decreased gonial angle were the greatest contributing components to deep bite malocclusion. The study analyzed 60 patients with deep bite malocclusion, and their cephalometric radiographs were used to measure the skeletal and dental components. The researchers measured the gonial angle, mandibular plane angle, maxillary and mandibular incisor inclinations, overbite, overjet, and curve of Spee. The results showed that the gonial angle was the highest contributing skeletal factor to a deep bite, and the exaggerated curve of Spee had the highest contributing dental component. The study also found that the lingual inclinations of the maxillary...

  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

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...
