Occlusion for Fixed Prosthodontics Flashcards
Optimal functional occluson=
Mutally protected occlusion
MIP and CR coincide in:
optima functional occlusion
The ____ teeth exhibit lighter occlusal contacts as compared to ____ teeth in MIP:
anterior; posterior
_____ teeth are axially loaded in MIP
Posterior
in mutually protected occlusion, in excursive movements:
canine guidance/anterior guidance occurs
The TM joints are in an optimum, orthopedically stable joint position when the mandible is in:
CR
In mutually protected occlusion, the anterior teeth disclude posterior teeth in ______ movements, thereby protecting the poster teeth from _____
excursive; off-axis loading
T/F: Anterior teeth are NOT axially loaded in MIP
True
T/F: Anterior teeth can tolerate lateral forces in excursive movements (off-axis loading) since they are further away from the fulcrum and the loads are less
True
Unilaterally balanced occlusion:
Group function
As the mandible moves laterally, its guided by a group of teeth (canines, premolars, & MB cusp of 1st molar) on the working side:
group function
B/L balanced occlusion:
balanced occlusion
Simultaneous contacts on both sides during lateral movements (W & NW sides) & between posterior/anterior during protrusive:
balanced occlusion
Balanced occlusion is not acceptable for:
dentate patients
-promotes tooth wear; NW contacts are destructive
-acceptable form of occlusion for CD & RPD
-contact on NW side can help stabilization of removable prosthesis
balanced occlusion
