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...

Comparison of clinical outcomes between Invisalign and conventional fixed appliance therapies in adult patients with severe deep overbite treated with nonextraction (summery)

-
Image
    The article discusses a study that compared the clinical outcomes of Invisalign and conventional fixed appliance therapies in adult patients with severe deep overbite. The study included 50 patients in each group and found that both treatments were effective in correcting overbite, but Invisalign may be preferable for patients with high angle and deep overbite.     The study also found significant differences in two postcephalometric linear measurements between the two groups. However, the study had a retrospective design, and the results should be viewed with caution. The study aimed to compare the effectiveness of Invisalign and conventional fixed appliance therapy in treating patients with a severe deep overbite.     The study included 100 adult patients with a severe deep overbite, with 50 patients receiving Invisalign therapy and 50 patients receiving conventional fixed appliance therapy. The study found that both treatments were effectiv...

Improvement of facial profile by nonextraction orthodontic treatment with temporary skeletal anchorage devices and visual treatment objectives (summary )

-
Image
     if you are intersted in this article please follow for more readings https://myorthodonticsblogg.blogspot.com/     👈🏻         This article discusses a case report of a 15-year-old girl with a convex profile and retrognathic chin who underwent non-extraction orthodontic treatment using temporary skeletal anchorage devices (TSADs) and visual treatment objectives (VTOs).     The treatment plan was presented to the patient and her parents using computer-generated VTOs, which allowed them to visualize the expected outcome of the treatment. The treatment objectives were achieved, and the patient's facial profile and occlusion were significantly improved.    The post-treatment records showed acceptable root parallelism, and there were no significant signs of bone or root resorption. The patient had a stable occlusion at the 12-month retention examination. The article highlights the use of TSADs in orthodontic tre...

Does anchorage loss differ with 0.018-inch and 0.022-inch slot bracket systems? (symmery)

-
Image
   if you are intersted in this article please follow for more readings https://myorthodonticsblogg.blogspot.com/     👈🏻      Orthodontic treatment is a common procedure used to correct misaligned teeth and improve the overall appearance of the mouth. One of the challenges of orthodontic treatment is maintaining proper anchorage, or the ability to keep certain teeth in place while others are being moved. In this study, researchers aimed to compare the effectiveness of two different fixed appliance systems in maintaining maxillary first molar anchorage during orthodontic treatment.    The study included 74 orthodontic patients who had undergone bilateral maxillary premolar extractions. The patients were randomly assigned to receive either a 0.018-inch or a 0.022-inch slot MBT bracket system.    The maxillary first molars were used as the anchor teeth, and the researchers measured the amount of anchorage loss in each group over...

Comparison of anterior retraction and anchorage control between en masse retraction and two-step retraction (Summary)

-
Image
     if you are intersted in this article please follow for more readings https://myorthodonticsblogg.blogspot.com/     👈🏻   Orthodontic treatment often involves the extraction of teeth to create space for proper alignment. However, closing the extraction spaces can be challenging, and different techniques have been developed to achieve this goal. This study compared two such techniques: en masse retraction (ER) and two-step retraction (TSR).  En masse retraction involves moving all the teeth in the extraction space as a single unit, while two-step retraction involves moving the posterior teeth first and then the anterior teeth. The study aimed to determine which technique was more effective in closing extraction spaces in adult patients.   The study found that both ER and TSR were effective in closing extraction spaces, with no significant differences in the amount of incisor retraction or anchorage loss of molars between the two meth...

The Dangers of Lingual Orthodontics for Orthodontists

-
Image
   if you are intersted in this article please follow for more readings https://myorthodonticsblogg.blogspot.com/     👈🏻 Introduction Orthodontic treatment involves the use of braces or other orthodontic appliances to correct malocclusion or misalignment of teeth and jaws. Lingual orthodontics is a type of orthodontic treatment that involves the placement of braces or other orthodontic appliances on the inside surface of the teeth. While lingual orthodontics can be an effective treatment option for patients seeking a discreet orthodontic treatment, it poses significant risks to orthodontists. This paper will examine the dangers of lingual orthodontics for orthodontists. Dangers of Lingual Orthodontics for Orthodontists Lingual orthodontics poses several dangers to orthodontists due to the placement of the orthodontic appliances on the inside surface of the teeth. The following are some of the dangers of lingual orthodontics for orthodontists: Difficulty in ...

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.

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...
