Occlusion Flashcards
When should you first evaluate your patient’s occlusion?
BEFORE preparing then try to replicate that in your restoration
What is the definiton of occlusion?
The way the maxillary teeth contact the mandibular teeth or vice versa
◦ Static
What is articulation?
The static dynamic relationship between occlusal surfaces during function
What is the goal of operative dentistry restorations?
*Good esthetics where applicable
*Restore function
* Minimize trauma to dentition
* Minimize after hour calls
* Ensure restoration lasts a long time
Teeth occlude with (contact) each other along their…
long axes
Which teeth overlap the others: max or mand?
Maxillary overlaps mandibular
What are the nonfunctional cusps on the maxillary?
buccal
What are the nonfunctional cusps on the mandibular?
lingual
Posterior teeth are ______ loading
AXIAL LOADING
◦ Load along LONG AXIS of the tooth
What is a cusp-fossa occlusion?
◦ Each functional cusp occludes in fossa of opposing tooth
◦ One to One tooth arrangement
What is cusp-marginal ridge occlusion?
◦ Each functional cusp contacts the MR OR fossa of the opposing pair of teeth
◦ One to Two teeth arrangement
◦ Most natural dentitions
What is the one to one tooth arrangement?
cusp-fossa
What is the one to two teeth arrangment?
cusp-marginal ridge
What can happen if you restore wrong?
*Pain on biting
*Fractured cusp
*Fractured restoration
*Premature wear on tooth
*Trauma to periodontal ligament
*Trauma to temporomandibular joint
*Angry patient
*Frustrated dentist
What are challenges that dentists face during restorations?
*Many patients do not have ideal occlusion
*Patients are often numb when asked to bite down and see if the restoration feels “normal”
*Patients have had their mouth open for the better part of 3 hours (or 30 minutes) when asked if
restoration feels normal
*I don’t think about how I bite until someone asks me if my bite feels normal
What do you use when evaluating if occlusion is high?
In patient, use articulating paper
What do you need to evaluate when checking occlusion?
◦ In patient, use articulating paper
◦ Evaluate in MIP
◦ Evaluate in excursives, protrusives
What is the high heel effect?
If a part of the restoration is left slightly high, you may have this effect
You need to check the patient’s occlusion with marking paper before what?
anesthetizing
Visually evaluate the _____________ side to where you are working during a restoration?
contralateral
Check the occlusion with patient in what orientation before they leave?
sitting up
