  • 1. INDIAN DENTAL ACADEMY Leader in continuing dental education www.indiandentalacademy.com www.indiandentalacademy.com
  • 2. OCCLUSION • RELATIONSHIPOF THE MAXILLARY AND MANDIBULAR TEETH WHEN THE JAWS ARE CLOSED IN CENTRIC RELATION WITHOUT STRAIN IN THE MUSCULATURE OR DISPLACEMENT OF THEIR CONDYLES IN THEIR FOSSA www.indiandentalacademy.com
  • 3. TERMINOLOGY • Anteroposterior: Overjet • Vertical: Deep overbite, Openbite • Transverse : Cross bite www.indiandentalacademy.com
  • 4. NORMAL OCCLUSION • In terms of molar relation. www.indiandentalacademy.com
  • 5. • Line of occlusion: Teeth should be arranged in a smoothly (catenary) curving line of occlusion. www.indiandentalacademy.com
  • 6. MALOCCLUSION TYPES • Dental (Dento-alveolar): abnormal relationship between the teeth themselves. • Skeletal: Both the upper and lower dentition may be normal but there may be associated skeletal defect. • Skeleto-dental: Combination www.indiandentalacademy.com
  • 7. PURPOSE OF CLASSIFICATION • Diagnosis and treatment planning • Comparison • Communication • Thinking of the possible treatment modalities that may be needed in a particular case. www.indiandentalacademy.com
  • 8. • ANGLE SYSTEM: Modifications: Lischers, Deweys, Howards, Taylors • SIMON SYSTEM • ETILOGICAL CLASSSIFICATION BY MOYERS • ACKERMANN AND PROFFIT CLASSIFICATION • BALLARDS SKELETAL CLASSIFICATION www.indiandentalacademy.com
  • 9. ANGLES CLASSIFICATION • Edward H. Angle in 1899 • Class I malocclusion • Class II malocclusion • Class III malocclusion www.indiandentalacademy.com
  • 10. CLASS I MALOCCLUSION • Lower dental arch is in normal relation to the upper dental arch. • Mesiobuccal cusp of the upper Ist molar occludes with the mesiobuccal groove of the lower first molar. • Irregularity of the individual teeth with normal dental arches. • 60 - 70% of all cases of malocclusion fall into this class.www.indiandentalacademy.com
  • 11. CLASS II MALOCCLUSION • The distobuccal cusp of upper first permanent molar occludes in the mesiobuccal groove of the lower first permanent molar. • Class II division 1 • Class II division 2 • Class II subdivision 1 • Class II subdivision 2www.indiandentalacademy.com
  • 12. Class II div 1 Extraoral features: • Convex profile • Deep mentolabial sulcus • Hyperactive mentalis muscle • Hypotonic upper lip • Incompetent lips www.indiandentalacademy.com
  • 13. Class II div 1 Intraoral features: • Class II canine and molar relationship • Increased overjet and overbite • Deep curve of spee • Constricted maxillary arch www.indiandentalacademy.com
  • 14. www.indiandentalacademy.com
  • 15. Class II div 2 Extraoral: • Competent lips • Well balanced face • Flat mandibular plane Intraoral: • Class II canine • Class II malar • Upper centrals: Retroclined • Upper laterals :Proclined • Upper arch: U shape • Supraeruption: lower ant. • Infraeruption: Lower post. www.indiandentalacademy.com
  • 16. CLASS III MALOCCLUSION • Upper permanent IInd premolar occludes with the buccal groove of the lower Ist permanent molar. • Constitutes to about 3% of malocclusion • also called Prenormal occlusion or Mesiocclusion. www.indiandentalacademy.com
  • 17. Class III malocclusion Extraoral features: • Concave profile • Mentolabial sulcus: Flat • Hypotonic lower lip • Hypertonic upper lip • Prominent chin Intral oral features: • ClassIII canine & molar • Reverse overjet • Curve of spee : Flat • Lingual inclination of lower incisors www.indiandentalacademy.com
  • 18. www.indiandentalacademy.com
  • 19. True Class III • Heriditary in nature • There is a definite skeletal defect and exhibits the following charecteristics:  Normal maxilla with prognathic mandible  Retruded maxilla with normal mandible  Combination of the above www.indiandentalacademy.com
  • 20. Pseudo Class III • Can occur due to following reasons: • Early loss of deciduous posterior teeth - Functional type of malocclusion. • Cleft lip & palate condition: Surgery is done in the early stage - retrained growth of the maxilla results - Psedo class III. • Presence of occlusal prematurities may deflect the mandible forward. www.indiandentalacademy.com
  • 21. DRAWBACKS OF ANGLE’S CLASSIFICATION • First permanent molars are not fixed points in the skull anatomy. • The classification of malocclusion is based on the anteroposterior relationship only. • The individual tooth malposition cannot be visualised. • When the Ist molars are extracted, this classification cannot be applied. www.indiandentalacademy.com
  • 22. DRAWBACKS OF ANGLE’S CLASSIFICATION • This classification cannot be applied to deciduous dentition. • The severity of malocclusion cannot be judged from this classification. www.indiandentalacademy.com
  • 23. INCISOR CLASSIFICATION • Class I: Lower incisal edges occlude with the middle part of the palatal surface of the upper incisors • Class II: Lower incisal edges lie posterior to the middle part of the palatal surface of the upper incisors. • Class III: Lower incisal edges lie anterior to the middle part of the palatal surface of the upper incisors. www.indiandentalacademy.com
  • 24. SIMONS CLASSIFICATION • 3 Planes are involved: • Frankfurt horizontal plane • Orbital plane • Mid-sagittal plane www.indiandentalacademy.com
  • 25. FRANKFURT HORIZONTAL PLANE • From the most superior point of external auditory meatus (porion) to the inferior border of the orbit (oribitale) • Attraction- Nearer to FHP. • Abstraction: Away from the FHP www.indiandentalacademy.com
  • 26. ORBITAL PLANE • This is perpendicular to FHP and also perpendicular to Median raphe plane/ • Protraction: Forward position of the jaw. • Retraction: Posterior position of the jaw. www.indiandentalacademy.com
  • 27. MID SAGITTAL PLANE • This is all the median raphe plane. • Contraction: Nearer to mid sagittal plane. • Distraction: Away from mid sagittal plane. www.indiandentalacademy.com
