Class I incisal relationship

Last edited: 4/15/2026

Overview

Class I incisal relationship refers to an occlusion where the upper incisors neither overlap nor are positioned lingually to the lower incisors, typically indicating normal or ideal anterior tooth alignment 1.

Diagnosis

  • Assessment of maxillary and mandibular incisor alignment 1.
  • No specific diagnostic tests; clinical examination sufficient 1.
  • Grading not typically applied in isolation; part of comprehensive occlusion evaluation 1.

    • Management

  • No specific treatments required if the relationship is naturally Class I and functional 1.
  • Orthodontic intervention may be considered for aesthetic or functional concerns 1.
  • Adjunctive treatments like occlusal adjustments may be performed in conjunction with orthodontic care 1.

    • Special Populations

  • No specific considerations mentioned for pregnancy, pediatrics, elderly, or comorbidities in the provided abstracts 1.

    • Key Recommendations

  • Conduct thorough clinical examination to confirm Class I incisal relationship without the need for additional diagnostic tests (Evidence: Expert opinion 1).
  • Address any functional or aesthetic concerns through orthodontic interventions if deemed necessary by the clinician (Evidence: Expert opinion 1).
  • Ensure comprehensive occlusion evaluation in all patients to contextualize the incisal relationship within overall dental health (Evidence: Expert opinion 1).
