🚀 Arch Coordination And Arch Symmetry: Avoid These Critical Mistakes!

  🚀 Arch Coordination And Arch Symmetry: Avoid These Critical Mistakes! Ever finished an aligner case only to realize the arches don't match or look unnatural? Let's clarify two key concepts: 🔹 Arch Coordination = Upper/lower arch harmony (interarch) 🔹 Arch Symmetry = Ideal U-shaped form (intraarch) Now let's break down the top mistakes—and how to fix them! ❌ Top Blunders Arch Coordination Fails: -Torque Mismatch – When upper/lower posteriors don't align, causing occlusal interference -CR Discrepancy – Arches that only fit in MIP but not centric relation Arch Symmetry Fails: -Forced "Perfect" U-Shape – Overriding natural anatomy leads to unstable results -Posterior Over-Expansion – Blowing out molars without anterior support creates "floating" buccal segments 💡 Pro Tips ( SoftSmile 's VISION™ Software solves both!) ✔ True Coordination Check – Test upper/lower arch fit in dynamic occlusion and CR ✔ Anchored Expansion – Maintain anterior contro...

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

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...
