1. OCCLUSAL EXAMINATION

2. PURPOSE OF INITIAL SCREENING EXAM
Screening device
Assist in identifying etiology of symptoms
Aid in treatment planning

3. OCCLUSAL EXAM maxillomandibular relationships
habits, underlying disease
tooth contacts during movement

4. Maxillomandibular Relationship
Molar
Anterior
Crossbite

5. Molar Relationship (Angle)
Class I (neutroclusion)
mesiobuccal cusp of maxillary first molar fits into buccal groove of mandibular first molar

6. Molar Relationship Class II (distoclusion)
Mandibular 1st molar distal to maxillary first molar

7. Molar Relationship Class III (mesioclusion)
mandibular 1st molar mesial to maxillary first molar

8. Anterior Relationship
CLASS I

9. Anterior Relationship
CLASS II

10. Anterior Relationship
CLASS III

11. Anterior Relationship
OPEN BITE
Failure of tooth/teeth to meet antagonists in opposing arch

12. CROSSBITE
ANTERIOR
Abnormal axial inclinations of maxillary teeth

13. CROSSBITE
POSTERIOR
Buccal cusp of mandibular teeth buccal to maxillary buccal cusp

14. Habits/Underlying Disease
WEAR
UNDERLYING DISEASE

15. WEAR Loss of tooth structure
attrition ( bruxism)
abrasion (external agent)
erosion (chemical reaction)
abfraction

16. OCCLUSAL WEAR

17. Underlying Disease - Mobility
Class I
Class II
Class III

18. MOBILITY
> 1mm of movement

19. Tooth Contacts during Movement
Physiologic
efficient function
state of health
Pathologic
damage to dentition

20. Working/Nonworking Contacts

21. PROTRUSIVE

22. CENTRIC RELATION VS. CENTRIC OCCLUSION
CR = most retruded, unstrained position of mandible, from which opening and lateral movements can be made
CO= position of maximum contact between maxillary and mandibular teeth - position of habitual closure
