TOOTH Prep Flashcards
(36 cards)
1
Q
WHAT IS PREPARATION
A
- Dentist usingSpecialDentistDrills(Burs )
- Tooth Reduction are Shaped such that they will be Capable of Receiving a Suitable Restorative Material. ( I.e., Dental Gold )
- MOST COMON PREPS: Chamfer Prep. - Shoulder Prep
2
Q
AMALGAM PREPS
A
- Created to receive Silver Filling Material.
- Once packed into tooth’s prepared area it is “MECHANICALLY LOCKED” in place.
- Prep is PURPOSELY “UNDERCUT**” to enhance the **Mechanical Lock.
3
Q
GOLD INLAYS PREPS
A
Teeth prepared to receive a GOLD INLAY instead of AMALGAM will be Shaped WITHOUT “Mechanical Locks.. (Undercuts).
4
Q
EXAMPLES OF RESTORATIONS

- Acrylic Composites
5
Q
MECHANICAL LOCK IS: UNDERCUT
A
- BOTH MEANINGS IS THE SAME.
- Notch Cut within Side of Tooth on Both Sides to Strengthen Fillingfrom Falling Out.
6
Q
MECHANICAL RETENTION

- CLASS 3: Mesial or DistalOFanAnterior Tooth.NOTInvolving the Incisal Angle
- CLASS 4: Mesial or Distal of an Anterior Tooth. Involves ONE or BOTH of it’s Incisal Angle
- CLASS 5: On the Facial Surface of ANY Tooth
16

A
- PREPARATION: Dentist Using Special Drills
- Restorative
- Mechanical Lock
20
Q
Denture-Bearing Areas
A
- Are the Residual Ridge and Hard Palate.
21
Q
The Border Extensions of a Maxillary
A
- The Border Extensions of a MaxillaryCompleteDentureareLimited by the..
- Labial Sulci,
- Buccal Sulci,
- PterygomaxillaryNotches and
- Vibrating Line.
22
Q
Retention
A
If the Resistance to Vertical Displacement at the Denture away from the Denture Bearing Surface During some Action.
23
Q
Stability
A
- By Definition: is the Resistance to Lateral Displacement at the Denture During Function.
24
Q
Support: is the resistance to..
A
- Vertical Forces to Occlusion.
- Various Factors are Related to the Tissue Bearing Surface that Resists or Absorbed a Occlusal Loads During Function.
25
**What Factors** that **Impact Retention,**
**Stability,** and **Support ?**
* The **nature of the bearing mucosa/tissue surfaces itself.**
* * Dose the **tissue bearing surface****have attached****or** **Unattached Gingival**.
* * **Bone Contour**, **Height** and **contour of Alveolar ridge**.
* * **Are any Tori Presen**t. Are there any Bony prominent
* * **Muscle Attachments**, **What are the positions** of various **Frenum** and **there size**, what's the floor of the mouth
26
**Mylohyoid Mucle**
* Is **Under Jaw Bone Next to Glands.**
27
* **DENTATE: Natural Teeth. 44 LBS**
* * **EDENTULOUS: Dentures 13-16 LBS**
* **DENTATE: Natural Teeth. 44 LBS**
* * **EDENTULOUS: Dentures 13-16 LBS**
28
**PHYSICAL Factors** are **Involved in Denture Retention**
* **Maximal Extension** of the **Denture Base, No Ridge Runners.**
* * **Maximum Coverage Provides Snowshoe Effect**
* * **Maximal Intimate Contact** with **Denture Base Muscular Forces** can be used to **Increase Retention Stability** of the **Dentures**
29
**Anatomical Landmarks of**
**Edentulous MAXILLA**
* **Incisive Papilla.** **Incisive Papilla** is the R**aised Soft Tissue Covering** the **Incisive Foramen Located** in the **Midline** of the **Hard Palate,****Behind**the**Central Incisors.**
* **Rugae. Rugae:** Are **Irregular Ridges** of **Fbrous Tissue** found in the **Anterior One-Third** of the **Hard Palate**.
30
**Median Palatine Raphe**
* **Median Palatine Raphe** is a **Slight Tissue Elevation Occurring** in the **Midline** of the **Hard Palate Immediately** over the **Median Palatine Suture.**
31
**Vibrating Line**
* **Vibrating Line** is the **Line of Fexion****Between**the**Hard**and**Soft Palates**
32
**Palatine Fovea**
* The **Palatine Fovea** are **2 Depressions** located on **Either Side** of the **Midline On** or **Very Near** the **Vibrating Line**.
33
**Labial Frenum**
* The **Labial Frenum** is a **Narrow Fold** of **Oral Mucosa****found**in the**Approximate Midline**.
* * It **Extends** from the **Inner Surface of the Lip** to the **Labial Surface** of the **Alveolar Ridge**.
34
**Buccal Frenum**
* **Buccal Frenum Extends** from the **Mucosa** of the **Cheek** to the **Buccal Aspect of the Alveolar Ridge.**
* * There are **Two Buccal Frena.**
* * They are **Located** on each side of the **Arch, Usually** in the **First Premolar Region.**
35
**Sulci**
* The **Maxillary Sulcus** is a **Groove Formed** by the **Mucosa** of the **Cheek** or **Lip** and the **Mucosa** at the **Base** of the A**lveolar Ridge**.
36
**Anatomical Landmarks of**
**Edentulous Mandible**
**Alveolar Ridge:** After **Natural Teeth** are **Extracted**, the **Remnant** of the A**lveolar Process** is called the **Alveolar** or **Residual Ridge**.
**Retomolar** **Pad:** The **Retromolar** **Pad** is a **Pear-Shaped Mass** of **Soft Tissue****Located**at the**Posterior End**of the**Mandibular****Alveolar****Ridge**.
