What do you look for when evaulating an abutment tooth?
|
-Before tooth prep (intraoral exam, radiographic exam, DX casts, DX waxup
-Unrestored (healthy) -Restored (Periodonal health, Presence/absence of caries) -Supraerrupted -Mesially inclined |
|
|
What is the difference b.t functional and parafuncitonal movements?
|
-Functional Movements: Chewing and Speaking
-Non-functional movements: Bruxism, Clenching |
|
|
What is mutually protected occlusion
|
-Uniform contact position when condyle is in the most anterior superior position
-CR=MI -No contacts in posterior during eccentric movements -Canine guidance in lateral movements -Anterior guidance in protrusive movements |
|
|
Why are gingival bevels sometimes used?
|
-used to create space
|
|
|
What are considered with mesially inclined teeth?
|
-Clinical crown
-Crown to root ratio -Mutual parallelism -Root surface area -Occlusal wear -Location of proximal contacts -Relative tooth dimension |
|
|
Describe the tendency of proximal contact?
|
-Move progressively gingivally and lingually
-Getting bigger distally -Tendency for root proximity, especially in molars |
|
|
Ideal common path of insertion relative to?
|
-Pulpal tissue
-Adjacent teeth -Occlusal force vectors -Esthetic demands |
|
|
Route to success for crown preparation?
|
-Make a cut guide out of putty
-Depth cuts -Occlusal prep. -Facial reduction -Interproximal reduction (use 169L) -Lingual reduction -Functional cusp reduction -Finish line |
|
|
Path of draw (2 types)
|
-One common path of inseration perpendicular to the occlusal plane
-One common path of inseration along the long axis of teeth |
|
|
What are the benefits and problems with using a Protemp crown?
|
Advantages:
-Preformed sizes for custom fits -Work well in emergency situations -Light curable with low heat generated -Easy to add to Disadvantage: -Expensive -Not as successful as other provisional options |
|
|
What technique can be used when there is difficulties achieving a common path of draw with prep?
|
-Hold handpiece at same angle when moving from one prep to next.
