T2 WEEK 13 PROS Occlusion by Abuzar
(COMPLETE) questions & 100% correct
answers.
how is 'occlusion' defined? ANS - - the 'static relationship between the incising or masticating surfaces
of maxillary and mandibular teeth or tooth analogues'
(Glossary of prosthodontic terms JPD July 2005).
however, a broader more comprehensive definition of 'occlusion' has been suggested considering all
components of the functional system including the TMJs, teeth, the periodontium and the
neuromuscular components involved with mandibular movement. ANS - - occlusion is the dynamic
biological relationship of the components of the masticatory system that determines tooth relationships
such as:
> TMJ
> muscles of mastication and the nervous system
> teeth or tooth analogues
what are the (4) key muscles that control Mn movements (mastication and other functions)? ANS - 1.
masseter
2. medial pterygoid
3. lateral pterygoid
4. temporal
NOTE: know how to palpate them. explain to pt the Tx so they understand the limitations
TMJ ANS - - anatomy
- physiology
, - function and joint disorders
NOTE: understand Mn movements. condylar positions and anatomy etc
what are the factors to consider for tooth analogues? ANS - • morphology of the occluding surfaces
(angles of cusps)
• occlusal plane (A-P)
• occlusal interface forces acting on teeth - masticatory, parafunctional (cleching, bruxing) and other
forces active over a prolong period of time
(forces generated by tongue and cheeks, eruptive, transseptal forces - Wiscott JPD 1995)
• tooth support (periodontium and force transmission)
what is the importance of jaw relationships and tooth contacts - relationship between Mn and Mx
teeth? ANS - - for diagnosis, treatment planning, setting up of occlusion in restorations/prostheses
- also for writing laboratory prescriptions during restorative procedures and writing of clinical reports
ANS - pt has severe 100% overbite
traumatic occlusion
did not require full mouth rehab
NOTE: should not increase VD in UG clinic, either removable or fixed
ANS - NOTE: know lab processes well as this will help with trouble-shooting problems with prosthesis
