Abstract.
Class III malocclusion is among the most challenging dentofacial
problems due to its multifactorial etiology, phenotypic heterogeneity, and
variable growth trajectories. Defined by a negative sagittal jaw relationship and
anterior crossbite tendency, it encompasses combinations of maxillary
deficiency, mandibular excess, or both, compounded by dentoalveolar
compensations. Beyond esthetic concerns, Class III discrepancies can
compromise mastication, speech, periodontal health, temporomandibular joint
function, and airway, with psychosocial impacts that often begin early in life.

Introduction:
Class III malocclusion represents one of the most complex
and clinically significant forms of dentofacial anomalies, characterized by
disrupted occlusal relationships in which the lower jaw occupies a more anterior
position relative to the upper jaw. This pathology is among the most common
orthodontic problems encountered in various age groups and requires a
comprehensive interdisciplinary approach to diagnosis and treatment. In
modern dentistry. Prevalence varies widely across populations, being higher in
East Asian groups and lower in European cohorts, underscoring the need for
culturally and biologically attuned diagnostic and therapeutic strategies.
Contemporary diagnosis must move beyond traditional 2D cephalometrics
alone. While measures such as ANB and Wits appraisal remain foundational,
they can be misleading in severe skeletal Class III patterns. Enhanced
assessment integrates 3D cone-beam CT when indicated, digital dental models
with virtual occlusion, facial soft-tissue analysis, and alternative sagittal
indicators (e.g., Beta and Yen angles). Functional evaluation of airway, tongue
posture, and muscular balance, together with growth assessment via cervical
vertebral maturation and serial superimpositions, improves prediction of

treatment response and stability. Increasingly, digital workflows, artificial
intelligence–assisted cephalometry, and predictive modeling offer opportunities
to standardize measurements and forecast growth, though clinical validation
and ethical deployment remain essential.
Treatment planning hinges on timing, severity, and patient-specific risk. In
the mixed dentition, interceptive orthopedic approaches—such as rapid
maxillary expansion with facemask protraction, Alt-RAMEC protocols, and bone-
anchored maxillary protraction using miniplates—seek to harness growth and
produce more orthopedic than dentoalveolar change. In adolescents nearing
growth completion, hybrid strategies leveraging temporary anchorage devices
can expand options for dental camouflage while reducing reliance on
compliance-heavy mechanics. For skeletally mature patients with pronounced
discrepancies, orthognathic surgery (Le Fort I advancement, bilateral sagittal
split osteotomy, or bimaxillary procedures) remains the gold standard,
increasingly guided by virtual surgical planning and 3D-printed splints. Across
all ages, aligner-based therapies are evolving as adjuncts or alternatives in select
camouflage cases, but evidence-based protocols and torque control strategies
are critical. Long-term stability and relapse risk, influenced by growth, soft-
tissue balance, and occlusal finishing, require proactive retention planning and
longitudinal monitoring.
Despite decades of research, key gaps persist: variability in phenotypes
leads to inconsistent protocols; predictors of response to early protraction or
skeletal anchorage are not uniformly applied; objective, patient-centered
outcomes are underutilized; and digital innovations are unevenly integrated into
routine care. A pragmatic, phenotype-driven framework that unites robust
diagnostics with age- and severity-specific treatment pathways is needed to
improve predictability, efficiency, and stability.
Class III malocclusion occupies a special place among dentofacial anomalies
due to its multifactorial etiology, complexity of clinical manifestations, and
significant impact on the functional state of the dentofacial system. According to
epidemiological studies, the prevalence of Class III malocclusion in various
populations ranges from 3% to 15%, with an observed tendency toward
increased frequency of this pathology in recent decades.
The development of modern technologies opens new possibilities for
improving diagnosis and treatment of Class III malocclusion. Implementation of
three-dimensional visualization methods, computer modeling, digital treatment

planning technologies, and biomechanical analysis allows for increased
diagnostic accuracy and effectiveness of therapeutic interventions.
Conclusions:
Development of preventive approaches to preventing Class III
malocclusion formation is a promising research direction. Early diagnosis of risk
factors, development of preventive intervention programs, and creation of
dispensary observation systems can significantly reduce the frequency of severe
forms of this pathology and improve treatment prognosis. Implementation of
telemedicine technologies in orthodontic practice opens new possibilities for
remote monitoring of patients with Class III malocclusion. Development of
mobile applications for patient self-control, remote treatment monitoring
systems, and teleconsultation can increase effectiveness of therapeutic
interventions and improve patient treatment adherence
