THE EDITOR'S CORNER

You Have No Enemies, You Say?

NEAL D. KRAVITZ DMD, MS

Every January issue of JCO focuses on a single, pressing topic. In recent years, we’ve explored airway orthodontics, tooth substitution, and treatment failures. This year’s issue examines the rise of ...

JCO ROUNDTABLE

Managing Erroneous Care

NEAL D. KRAVITZ DMD, MS, GAYLE GLENN DDS, MSD, BILL LAYMAN DMD, MBA, BJÖRN LUDWIG DMD, MSD, RAVINDRA NANDA BDS, MDS, PhD, JAE HYUN PARK DMD, MSD, MS, PhD, VISHNU RAJ BDS, MSFS, MS

Leaders in orthodontics examine how diagnostic failures, aligner misuse, airway-driven treatment claims, and emerging technologies such as artificial intelligence can contribute to iatrogenic outcomes. The discussion emphasizes clinical responsibility, decision-making limits, and practical strategies for recognizing and managing erroneous care.

The Mewing Trend

NICKY STANFORD BSc (Hons), BDS, MSc, MFDS RCS, MOrth RCS, FDS RCS, FHEA

The evolution of mewing is traced from a fringe orthodontic concept to a widely promoted social media phenomenon. The article critically reviews the scientific evidence behind claims of facial growth modification, while offering guidance for clinicians faced with patient misconceptions.

Premature Implant Placement and Prolonged Orthodontic Treatment

BJÖRN LUDWIG DMD, MSD, PhD, NIKOLAS WILHELM DMD, MSc, LEVENTE SZEGEDI DMD

A compromised anterior implant case illustrates the long-term consequences of premature implant placement and inadequate interdisciplinary coordination. Through diagnostic reassessment, digital setup, and carefully controlled mechanics, this demonstrates how a stable and acceptable outcome can still be achieved.

Treatment of Complications Associated with Advanced Lightwire Functional Appliance Therapy in Adult Patients

SEONG-HUN (SUNNY) KIM DMD, MSD, PhD, JUNG JIN PARK DDS, MSD, PhD

Documented adult cases are used to analyze severe clinical complications associated with functional “growth appliance” therapy. The authors highlight biologic limitations, treatment instability, and the challenges of retreatment when appliances are promoted beyond their orthodontic indications.

Detrimental Effects Associated with the Anterior Growth Guidance Appliance

NEAL D. KRAVITZ DMD, MS, CLAIRE SHULTS DDS, MSD, JEFFREY C. MILLER DDS, KELTON T. STEWART DDS, MS

Through a detailed patient history and clinical documentation, the authors explore the biomechanics of AGGA therapy and clarify why toothborne appliances cannot produce skeletal growth in adults. The article underscores how misinterpretation of treatment effects can result in irreversible periodontal and dental damage.

50

The Fallacy of "Extraction Regret Syndrome"

JEFFREY C. MILLER DDS, GRACE E. HUTCHINSON, COLIN RICHMAN DMD, BDS, LDS RCS, HDD

The concept of extraction regret is examined as a cultural and clinical phenomenon influenced by misinformation. Using CBCT-based assessment, the authors focus on alveolar boundary conditions, biologic constraints, and the periodontal risks associated with orthodontic tooth movement.
