Prevalence of AOB in mixed dentition: 17.7% (~1 in 5 orthodontic patients) Major independent risk factors: Prolonged sucking habits (thumb/finger or dummy) beyond age 3 Facial hyperdivergency (skeletal vertical excess) Highest risk group: Patients with both prolonged sucking habits + hyperdivergent face AOB prevalence 36.3% → ~4× higher than those without risk factors (9.1%) AOB Diagnosis: Overbite ≤ 0 mm, with all permanent incisors fully erupted. Facial […]

🎯 3-5-7 Rule for Duration & Risk Stop by 3 → Minimal risk Stop after 5 → Moderate risk (AOB, PXB start appearing) Stop after 7 → High risk (Multiple malocclusions likely) 🍼 Pacifier vs. 👍 Digit — Think “Short vs. Strong” Pacifier = Short habit (≈14 mo), causes AOB + Class II if ≥4 yrs Digit = Strong persistence (≈33 mo), causes AOB if ≥5 yrs Duration […]

Maxillary Skeletal Expander (MSE) Type: Micro-implant-supported expander (MARPE) Anchorage: 4 bicortical miniscrews (palatal + nasal cortex) Placement: Posterior palate Expansion rate: 2 turns/day until diastema Then 1 turn/day Retention: ≥ 3 months post-expansion Parameter Mean Increase Anterior Inter-Maxillary Distance (AIMD) +2.76 mm Posterior Inter-Zygomatic Distance (PIZD) +2.40 mm Posterior Inter-Temporal Distance (PITD) Negligible Parameter Mean Increase Zygomatic Process Angle […]

In this exclusive interview, we sat down with Prof (Dr.) Ghanta Sunil — a passionate academician and curriculum reform advocate — to talk about the urgent need to upgrade the dental curriculum. With decades of experience, an eye on the future, and feet firmly grounded in educational values, Dr. Ghanta Sunil breaks down what’s missing, what must change, and how the next generation of dentists can be better prepared for a complex and compassionate future.

Examining the abdomen in quadrants remembering the organs that occupy the quadrants will give an indication of the problem for example: 👉🏼Pain in all quadrants with associated vomiting and diarrhea may indicate gastroenteritis. 👉🏼Colicky pain in all quadrants may indicate an obstruction of the bowel. 👉🏼Pain from appendicitis is usually in the right lower quadrant. […]

🔍 Overview Procedure: ASO corrects bimaxillary dentoalveolar protrusion, primarily in Asian populations. Goal: Predict soft tissue (ST) changes from hard tissue (HT) movements. Method: Systematic review of 11 studies (199 patients; lateral cephalometry used in all). Region Change Upper lip (Ls) Retrusion: −0.9 to −7.25 mm Vertical change: −2.4 mm to +1.2 mm Lower lip (Li) […]

Scenario T-Loop Position Resulting Effect Standard retraction with equal control Centered Balanced α and β moments; negligible vertical force Need to anchor molars (prevent mesial drift) Posterior ↑ Beta moment, molars stabilize; anteriors retract + intrude Need strong anterior retraction with minimal molar effect Anterior ↑ Alpha moment, anteriors retract efficiently, but risk of extrusion […]

Deep bites are tricky—not just vertically, but also in the sagittal and transverse planes. But what if you could correct both anterior and posterior segments simultaneously with calibrated force? Enter the 0.016-inch distal extension, an appliance designed to erupt and rotate both halves of the arch in harmony. ✅ Growth potential remains — you need an eruptive force. ✅ Second-order discrepancy: Incisors are […]

When managing a deep overbite, we often think about intrusion arches, curve of Spee leveling, or anterior bite turbos. But have you met the “base arch”? This humble-looking yet biomechanically brilliant appliance does more than you expect — especially when molar control and occlusal plane leveling are your goals. Also called the intrusive arch, the base arch shares design features with the tip-back mechanism: […]

You’re treating a teenage patient with: A deep curve of Spee, Mild arch length deficiency (~1–2 mm), And an anterior crowding with slightly flared lower incisors. You’re not quite ready for extractions, and distalization isn’t needed in full force. You just need a smart trick to upright the molars and gain that precious 1–2 mm of space per side. What […]

📍Scene: Department of Orthodontics, South India You’re sipping your 4th cup of filter kaapi ☕, scrolling through cephs, and bam! You spot that patient who walks in looking like they’re always mid-pout. Not because they’re annoyed – but because their upper and lower jaws are both chillin’ way ahead of where they’re supposed to be! Say hello […]

Hey there, future smile designers! 👩‍⚕️👨‍⚕️ Let’s take a dive into something that keeps many orthodontists up at night (besides coffee and ceph tracings): Class II malocclusion—aka the “Oops, my mandible missed the memo to grow” situation. 😅 Imagine your upper jaw (Maxilla the Diva 💁‍♀️) is strutting too far forward, while the lower jaw (Manny […]

Today, we’re diving into the long-term success of comprehensive Class II correction. That’s right—grab your elastics and settle in, because this one’s going to be more enlightening than a mid-treatment ceph. Now, when it comes to treating Class II malocclusion, there’s a question that keeps popping up like a stubborn second molar: What makes the […]
