|
1. the single, U-shaped incisive bone
2. right maxillae bone 3. left maxillae bone |
|
Which maxillary bone is most rostral and contains the maxillary incisors? What is another name for this bone?
|
incisive bone
aka: primary palate |
|
What is a secondary palatal cleft and where is it located?
|
A midline defect behind the incisive bone
|
|
What is a primary palatal cleft and where is it located at?
|
A defect between the incisive bone and maxillae
|
|
What is a primary palatal cleft called when the lip is involved?
|
cleft lip
|
|
What are the three regions of the mandible?
|
1. the symphysis
2. The body 3. The vertical ramus |
|
The condyloid process at the distal aspect of the mandibular vertical ramus articulates with? What joint is formed?
|
the mandibular fossa of the temporal bone as the temporomandibular joint
|
|
The coronal process lies where to the zygomatic arch?
|
medial
|
|
What makes up the periodontium?
|
1. attached gingiva
2. periodontal ligament 3. cementum 4. alveolar bone |
|
What is the part of the oral mucosa that covers the alveolar process?
|
gingiva
|
|
What term describes the proliferation of the attached gingiva?
|
gingival hyperplasia
|
|
What term describes the exposure of the tooth roots caused by the retraction of the gingiva secondary to periodontal disease?
|
gingival recession
|
|
What term describes the normal space between the free gingival margin and the epithelial attachment?
|
gingival sulcus
|
|
What is the reversible inflammation of the gingival tissue called?
|
gingivitis
|
|
What is the name of the line that separates the thick protective attached gingiva from the alveolar mucosa?
|
mucogingival junction (MGJ)
aka: mucogingival line (MGL) |
|
The MGJ remains stationary throughout life although the gingiva around it may change in height due to what possible disease processes?
|
-gingival recession
-gingival hyperplasia -attachment loss |
|
What is the name of the tissue that is loosely attached nonkeratinized tissue that lies apical to the mucogingival junction?
|
alveolar (oral) mucosa
|
|
What are the three zones the gingival epithelium can be divided up into?
|
1. oral epithelium
2. sulcular epithelium 3. junctional epithelium |
|
What does the oral epithelium cover? what type of mucosa is it? What is another term for it?
|
-covers the oral surface of the attached gingiva and papillae
-keratinized or parakeratinized -aka outer gingiva epithelium |
|
What does the sulcular epithelium cover? what type of mucosa is it?
|
-an extension of the oral epithelium into the gingival sulcus
-nonkeratinized |
|
Where is the junctional epithelium located at? What does it attach to?
|
Separates the periodontal ligament from the oral environment. The junctional epithelium attaches to the root cementum immediately apical to the cementoenamel junction
|
|
What is the name of the tissue that surrounds and supports the teeth?
|
periodontium
|
|
The oral cavity is lined by what three types of mucosa?
|
keratinized, parakeratinized and nonkeratinized mucosa
|
|
What is the name of the tissue that covers the alveolar process surrounding the teeth?
|
attached gingiva
|
|
What type of mucosa is the attached gingiva?
|
keratinized
|
|
The gingiva includes what three types of epithelium?
|
1. oral epithelium
2. sulcular epithelium 3. junctional epithelium |
|
What is the name of the most coronal aspect of the gingiva?
|
marginal gingiva
|
|
Does the marginal gingiva attach to the tooth?
|
no but it lies passively against it
|
|
The space between the tooth and the marginal gingival is called?
|
gingival sulcus
|
|
What is the coronal edge of the marginal gingiva?
|
free gingival margin
|
|
What distinguishes the free gingival margin from the attached gingiva?
|
the free gingival groove
|
|
What is the free gingival groove?
|
A slight depression on the coronal gingiva corresponding to normal sulcus depth
|
|
What attaches the cementum to the alveolar bone by collagen fiber bundles? (sharpey's fibers)
|
periodontal ligament
|
|
What are the 4 functions of the periodontal ligament?
|
1. sensation
2. holding the tooth in it's socket 3. cushioning of forces to the tooth 4. separation of the dentin from bone |
|
What is the name of the fibrous and cellular layer that covers bone and contains cells that become osteoblasts?
|
periosteum
|
|
What is an acute disease state of the periodontium?
|
periodontitis
|
|
What is periodontal splinting?
|
stabilization of mobile teeth by attaching the teeth to nonmobile adjacent teeth
|
|
What are the four indications for attempting periodontal splinting?
|
1. To accompany the healing phase of periodontal therapy
2. For stabilization after trauma 3. For stabilization before and during periodontal therapy 4. As a method to temporarily save teeth that would have been extracted because of advanced support loss |
|
What equipment is needed for periodontal splinting?
|
- dental acrylic or composite
- composite filling material - bondable reinforcement ribbon |
|
What is periodontal regeneration?
|
a variety of surgical techniques that attempt to restore the periodontal tissue lost through disease
|
|
What is the goal of periodontal regeneration?
|
to replace the bone and lost attachment
|
|
What are the basic steps when performing periodontal regeneration?
|
1. flap exposure
2. open root planning 3. placement of a bone product- bone induction products, or a membrane over the treated area before resuturing- i.e. bone graft |
