Evidence in Orthodontics

Discover how 3D printing is transforming orthodontics in this concise study summary: - Researchers tested a 3D printed customized face mask for treating class 3 malocclusion in children. - Comparison: 3D face mask vs. conventional petit type face mask. - Study Details: 34 children, ages 7-12, followed over 9 months. 3D printing is enhancing patient comfort in orthodontic treatments, marking an imp...

In this episode: - Analysis of poster abstracts from the European Orthodontic Congress. - Focus on whether conclusions are based on clinical relevance or statistical significance. - Concerns raised about over-reliance on p-values and lack of reporting on effect sizes and confidence intervals. - Call for clearer guidelines and collaboration between clinicians to ensure meaningful research. Statisti...

Explore whether smartphones can replace DSLRs for dental photos: - Research by Kiran Deepnandra et al. compared smartphones and DSLRs. - Findings: DSLRs offer superior image quality and accuracy; Samsung S23 Ultra smartphone performed well. - Ease of use: Both devices similar, but DSLRs allow consistent framing. - Color accuracy: Poor across both tools, with only 20% correct shades. - Recommendati...

Learn how early treatment of unilateral posterior crossbite can: - Improve condyliosymmetry in children. - Enhance jaw joint balance. - Influence facial growth and symmetry. - Change mandible rotation from clockwise to counterclockwise. - Guide mandibular growth, not just align teeth. Study Highlights: - 52 children with mixed dentition were treated. - Condyliosymmetry improved from 10% to 6% asym...

Explore if 3D scans, like CBCT, enhance treatment plans for impacted canines: - A study by Aarhus University checked if CBCT changes plans compared to 2D x-rays. - Results showed that plans changed in about one-third of the cases post-CBCT. - Most changes involved traction direction, not extraction decisions. - CBCT detected root resorption more frequently than 2D x-rays, but it rarely influenced...

Comparison: - Analyzed tooth-borne vs. tooth-borne-borne RME appliances - Conducted via a randomized controlled trial with a five-year follow-up Outcome: - Both appliances stable long-term - Minimal clinical differences despite measurable variation Recommendation: - Standard tooth-borne expanders sufficient for young patients - Hybrid design may aid older adolescents or cases with higher skeletal...

Study Overview: - Multi-center randomized control trial from Sweden. - Compared open vs. closed surgical techniques for palatally displaced canines. - Included 120 patients aged 9 to 16. Key Findings: - Eruption Speed: Open group's canines erupted about 3 months faster, though total treatment time was identical for both at around 26 months. - Patient Comfort: Closed technique reported more pain an...

Explore the efficacy of Miniscule-Assisted Rapid Palatal Expansion (MARPE) in older patients: - Evaluated via a systematic review and meta-analysis. - 92% success rate in mid-palatal suture opening without surgery. - Average skeletal change: 2.3 mm, total dental expansion: 6.5 mm. - Includes limitations: high risk of bias, lack of randomized trials. - Side effects: molar tipping, buccal bone thinn...

Topic: Palatal Suture Maturation Classification and CBCT Imaging Key Points: - Study Focus: Evaluation of the palatal suture maturation classification through CBCT in orthodontics. - Main Findings: - High intra-examiner agreement, poor inter-examiner agreement. - Limited predictive power for skeletal or dental outcomes. - Recommendations: Caution in using this system for treatment decisions; rely...

Explore the factors influencing dental referrals as general dentists decide which orthodontists to recommend. Key points include: - Treatment Quality & Patient Satisfaction: Valued equally by dentists. - Referral Criteria: Based predominantly on treatment results over cost, location, or reputation. - Important Features: Canine guidance, class I molar relationships, and patient profile. - Trust & C...

Discover the impact of bisphosphonate therapy on orthodontic treatment: - Bisphosphonates: Used for osteoporosis and cancers, inhibit osteoclasts, slowing bone resorption and tooth movement. - Research Findings: Tooth movement is slower, space closure may be incomplete, and root parallelism compromised. - Patient Risks: High-risk cancer patients may develop osteonecrosis of the jaw; low-risk osteo...

- Analysis from Alexandria University on closing anterior open bites using extrusion arches in adults. - 23 adult women with moderate open bites were treated. - Results showed overbite improvement and stable closure within 4 months. - Upper and lower incisors extruded and uprighted; molars slightly intruded and tipped mesially. - Highlighted limitations: all-female subjects, no control group, shor...

Conclusions: - Children with class 2 division 1 malocclusion treated with plaques twin-block show: - No significant differences in maxillary incisor retroponation. - No significant skeletal change. - No significant difference in overjet reduction rate. - An upper labial bow can be excluded without negative effects. --- Take Your Practice to the Next Level! Feeling overwhelmed trying to figure out...

Our systematic review reveals: - No significant differences in aesthetic outcomes between orthodontic treatments with or without premolar extraction. - Premolar extractions benefit those with: - Greater lip protrusion - More convex facial morphologies - Shorter treatment duration without extractions. - Cephalometric parameter LIE aids decision-making in borderline cases. --- Take Your Practice to...

In "Equilibrium Theory Revisited," the video updates a classic dental concept. It discusses the landmark 1978 study on the Franco-functional regulator (FR1) for treating class 2 malocclusion in pre-pubertal children. Key findings include: - Use of FR1 appliance resulted in a forward shift of the mandible. - Reduction in overjet and improved soft tissue balance were observed. - Study limitations: n...

Canine Protected Occlusion: Rethink the Norm - Traditional belief: Canines should exclusively contact during lateral excursions. - New evidence suggests balanced occlusion is more common. - EMG studies and data show occlusal form contributes little to TMD. Every patient is unique: Chewing patterns, craniofacial morphology, and parafunction matter. --- Take Your Practice to the Next Level! Feeling...
