Periodontal Flap Procedures (Part I) Flashcards
Regeneration =
New alveolar bone, cementum & PDL
Describe new attachment in tissue attachment-healing:
The union of connective tissue with a root surface
The union of connective tissue with a root surface that has been deprived of its original attachment apparatus:
New attachment
Give an example of new attachment seen in tissue attachment-healing:
reunion of connective tissue with the root surface which has been pathologically exposed
The reunion of connective with a root surface which has been pathologically exposed:
New attachment
The reunion of connective tissue with a root surface on which viable periodontal ligament tissue is present:
Reattachment
Example: where biologic width (now termed supracrestal tissue attachment) existed before a flap was reflected, and when the flap is replaced, reattachment occurs with the intact connective tissue fibers:
Reattachment
New name for biologic width:
Supracrestal attachment
We reflect a flap, stitch it back down, and over time it heals back to normal. This is an example of:
Reattachment
The healing of a wound that does NOT fully restore the architecture or function of the part:
Repair
What is the primary example of repair:
Healing by a long junctional epithelium
Healing by a long junctional epithelium:
Repair
Provide a term for the following definitions:
- Reproduction or reconstitution of a loss or rendered part
- The union of connective tissue with a root surface that has been deprived of its original attachment apparatus:
- The reunion of connective tissue with a root surface on which viable PDL tissue is present:
- The healing of a wound that does not fully restore the architecture or function of the part
- Regeneration
- New attachment
- Reattachment
- Repair
Scar formation is an example of:
Repair
Why is scar formation an example of repair?
Scar formation closes that area effectively but does not fully restore architecture or function
When you have root planed an area, and the 10mm pocket is now 3mm, the 7mm difference is due to:
repair
When ALL soft tissue including the periosteum is reflected exposing the underlying bone:
Full thickness flap
The most commonly used flap:
Full thickness flap
A full thickness flap may also be called:
Mucoperiosteal flap
A mucoperiosteal flap is another name for:
Full thickness flap
When epithelium and SOME connective tissue is reflected, leaving periosteum and some connective tissue overlying the bone:
Partial thickenss flap
A partial thickness flap may also be called:
Split thickness flap
A split thickness flap may be used to describe:
A partial thickness flap
When creating a flap, the incisions should always:
be down to the bone
List the principles of tissue attachments: (5)
- Preparation of soft tissue wall
- Preparation of root surface
- Debridement of bony defects
- Adaptation of soft tissue to root surface
- Control of etiology pre- & post- surgery
List the root changes hindering tissue attachment: (4)
- foreign body nature of exposed diseased root surfaces (presence of endotoxin)
- Endotoxin absorbed on & into cementum
- Pathologic changes in root surface (hypo- & hypercalcification areas)
- Decreased organic material in exposed cementum (loss of fibers and alterations in the organic material related to endotoxin)
