What is the difference between an impacted tooth and an unerupted tooth?
|
Impaction - tooth blocked from normal eruption
Unerupted - tooth not yet erupted or blocked from eruption |
|
Which teeth are most commonly impacted and why?
|
3rd Molars - last to come in - jaws not big enough
Canines - not enough space Lower Bicuspids - Not enough space |
|
Should you remove impacted teeth?
|
Yes
All should be removed unless contraindicated |
|
Why should you remove impacted teeth?
|
To prevent
1. perio disease 2. caries 3. pericoronitis 4. root resorption 5. under prosthesis 6. associated cysts or tumors 7. orthodontic reasons |
|

|
Pan
|
|
What is an infection of soft tissues covering part of the crown by normal oral flora?
|
Pericoronitis.
|
|
What are the components of Pericoronitis?
|
1. Infection of soft tissue covering part of the crown by normal oral flora
2. When Resistance Lowered 3. Secondary to Trauma of maxillary tooth to operculum 4. Entrapment of Food |
|
Whick lymph nodes are most often swollen as a result of pericoronitis?
|
Submental lymph nodes
|
|
How do you Tx pericoronitis?
|
1. H2O2 irrigation - antianaerobes
2. Chlorhexidine irrigation 3. Antibiotics when indicated (do not remove operculum. It is not effective) |
|
What are the signs of SEVERE Pericoronitis?
|
Rubor (red)
Calor (fever) Dolor (pain) Tumor (local or general swelling) Interference w/Function (trismus) pneumonic: (look away now if you are easily offended) Rub Cock Dumb Trick yer Interfering with its Function |
|
What forms from follicle of an unerupted tooth?
|
Dentigerous cyst
|
|
When is the ideal age to have wisdom teeth removed?
|
17-20
Roots not fully formed Large Developmental Sac Bone Elastic Health Good |
|
What are orthodontic reasons to pull 3rd molars?
|
1. Jaws too small for 3rds
2. Tx reduces space for 3rds 3. Mesial pressure 4. Distal movement of 1st & 2nd molars Anticipated |
|
How are 3rd molar positions classified?
|
1. Angulation
2. Relationship to Anterior border of Ramus 3. Relationship to Occlusal Plane |
|
What are the different angulations of Mandibular 3rds?
|
Vertical
Horizontal Mesioangular Distoangular Transbuccally (crown facing lingually or buccally) |
|
What are the different relationships of the Ramus to the crown of the 3rd?
|
1. Ramus Posterior to crown
2. Ramus over 1/2 of crown 3. Ramus over entire crown |
|
What are the types of relationships of 3rds to the occlusal plane?
|
At Level of 2nd molar
Below Level of 2nd molar Deep under bone |
|
What are the Factors Influencing the Surgical Approach for Exo of 3rds?
|
1. Angulation
2. Ramus relationship 3. Occlusal relationship 4. Developmental sac 5. Root development 6. Surrounding bone 7. Relationship to 2nd molar 8. Relationship to inferior alveolar and lingual nerves 9. Overlying tissue |
|
What are the different types of Insurance Classifications for 3rds?
|
1. Soft Tissue Impaction
2. Partial Bony Impaction 3. Complete Bony Impaction |
|
Why is a Seldin Retractor better for retracting flaps than the Molt #9?
|
Seldin is wider
|
|
What is the Chisel and Mallet used for?
|
Bone removal
|
|
What is a coronectomy and what are some reasons you might do it?
|
Coronal portion of tooth removed only
1. if traumatic risk is high 2. Pericoronitis 3. Intimate relationship w/mandibular canal (passive eruption will follow) |
|
What is an Osteotome (wedge)?
|
Used to section tooth (but not a chisle)
|
|
**Why should you always put a retracter on D of Max 3rd?
|
So you don't elevate it into the infratemporal space.
|
|
What are the characteristics of the Ideal Alveolar Ridge?
|
1. Proper jaw relationship and intermaxillary space
2. U-shaped ridge 3. No bony or soft tissue protuberances or undercuts 4. Adequate attached keratinized mucosa in primary denture bearing area 5. Adequate vestibular depth 6. Adequate bone height and width 7. Fixed Tissue under dentures 8. Absence of redundant tissue 9. No obstructing frenae or scar bands 10. No displacing muscle attachments |
|
How does bone loss compare in the maxilla and mandible?
|
Max = posteriorly
Mand = downward |
|
What is the recontouring or reduction of a portion of the alveolar process?
|
Alveoloplasty
|
|
What are the goals of alveoloplasty?
|
Eliminate bony projections that result in undercuts
Improve the path of insertion of the prosthesis Eliminate bony sources of irritation |
|
What are the results of Intraseptal Alveoloplasty and Cortical Plate In-Fracture?
|
1. Periosteal attachment is maintained
2. Alveolar height is preserved 3. Alveolar width is lost |
|
What are disadvantages of alveoplasty?
|
You may want to preserve bone for implants
Adjacent vital structures like Maxillary sinus and mental foramen |
|
When would we remove tori and exostoses?
|
Chronic irritation
Inability to construct prosthesis |
|
When would you perform frenectomy?
|
Lingual Frenectomy - Speech or trauma
Labial Frenectomy - Denture stability or trauma |
|
How do you treat an epulis fissuratum?
|
