Intro Flashcards
1
Q
Incisional Biopsies are used when
A
- Lesion is >1cm
- Polymorphic
- Suspicious for malignancy
- In an anantomical areea with high morbidity
2
Q
Excisional Biopsies aree used
A
- Smaller lesions <1cm
- Vascular lesions
- Pigmented lesions
- Removal of entire lesion and a perimeter of surrounding uninvolved tissue
3
Q
Impacted teeth
A
- One that fails to erupt into dental arch within expected time
- Adjacent teeth, bone, soft tissue prevents it from erupting
- Mand 3rd molars, max 3rd molars, max canines are most commonly impacted
4
Q
Angulation of impacted teeth
A
- Mesioangular (least difficult)
- Horizontal
- Vertical
- Distoangular (most difficult)
5
Q
Pell and Gregory Classification
Relationship to the anterior border of the ramus
A
- Class 1
- Normal position anterior to ramus
- Class 2
- 1/2 of the crown is within the ramus
- Class 3
- Entire crown embeded within the ramus
6
Q
Pell and Gregory
Relationship to Occlusal Plane
A
- Class A
- Tooth at the same plane as the other molars
- Class B
- Occlusal plane of the 3rd molar is between the occlusal plane and the cervical line of the 2nd molar
- Class C
- the 3rd molar is below the cervical line of the 2nd molar
7
Q
Unerupted teeth
A
Includes both impacted and teeth that are in the process of erupting
8
Q
Embedded teeth
A
- Occasionally used to describe impacted teeth
- Inadequate arch length is the primary reason that teeth fail to erupt
- Most common teeth to become impacted are 3rd molars bc they are last
9
Q
Whattype of bone is better for implants
A
Denser cortical bone is better than loose, soft cancellous bone
10
Q
Autograft
A
Autogenous bone from patient
11
Q
Allograft
A
Cadaver bone processed sterility
Osteoconductive but not osteoinductive
12
Q
Bone Morphogenetic Protein
A
Induce bone formation and enhance graft healing
