All are indications for perio surgery except?
To remove epithelial tissue from inner wall of perio pocket
Indications for perio surgery
Provide access for improved perio instrumentation of root surfaces
Reduce pocket depths
Provide access to perio osseous defects
Respect or remove tissue
Regenerate the periodontium lost due to disease
Graft bone or bone stimulating materials into osseous defects
Improve the appearance of the periodontium
Enhance prosthetic dental care
Allow placement of a dental implant
Common contraindications for perio surgery
Pts who have certain systemic diseases or conditions
Pts who are totally noncompliant with self care
Pts who have a high risk for dental caries
Pts who have totally unrealistic expectations for surgical outcomes
Can you do surgery on a pt who is on dialysis?
Can you do surgery on a pt with seizures?
What is the goal of perio surgery?
For long junctional epithelium to form
Should all pts receive non surgical therapy along with surgical therapy?
Bone take from pts own body
Bone taken from another human
Bone taken from another species
Synthetic bone like material
How soon should you probe a bone graft site?
When dr says
How long do you leave a bone graft undisturbed?
Months or until dr says
Before surgery you should always..
Inform pt of changes that they may not like
Postsurgically you should...
Take medications as prescribed
Take it easy for several days
Eat soft foods
No hot beverages
Don’t chew on surgical site
Rinse with recommended mouth rinse
Healing of a wound by formation of tissues that do not precisely restore the original architecture or original function of the body part
What is an example of healing by repair?
The formation of a scar during the healing of an accidental cut finger
Healing of a periodontal wound by the reunion of the connective tissue and roots where these two tissues have been separated by incision or injury but not by disease
The union of a pathologically exposed root with connective tissue or epithelium
Biological process by which the architecture and function of lost tissue is completely restored
For healing of the periodontium to be described as ________ the healing would have to result in the formation of lost cementum, lost periodontal ligament, and lost alveolar bone
A procedure in which incisions are made in the gingiva or mucosa to allow for separation of the surface tissues (epithelium and connective tissue) from the underlying tooth roots and underlying alveolar bone
A full thickness flap is elevated with what is generally referred to as a
What is a full thickness flap also called?
Involves elevation of entire thickness of the soft tissue
Full thickness flap
What is a partial thickness flap also called?
Split thickness flap
Includes elevation of only the epithelium and a thin layer of the underlying connective tissue
Partial thickness flap
A partial thickness flap is elevated with
A flap that is sutured with the margin of the flap at its original position in relationship to the CEJ on the tooth
A flap that is sutured with the margin of the flap placed at a position other than its original position in relationship to the CEJ of the tooth
Which type of healing is expected from flap for access surgery?
Healing by repair and usually involved formation of a long junctional epithelium
Removal of some tooth supporting bone
Reshaping of the surface bone contours
During surgery to minimize periodontal pockets, it is common for the gingival margin to be positioned..
At a more apical level to the CEJ than originally occupied
What does the more apical positioning of the gingival margin result in?
Exposure of a portion of the root to the oral cavity
New bone cells and new bone that forms following bone grafting
A periodontal surgical procedure employed to encourage regeneration of lost periodontal structures (to regrow lost cementum, lost PDL, lost alveolar bone)
Guided tissue regeneration
What might be placed under a periodontal flap at the time of surgery to delay the ingrowth of unwanted types of cells into the healing of the wound?
A barrier membrane
A type of periodontal plastic surgery that was one of the first procedures to augment the width of attached gingiva
Free gingival graft
What does the donor tissue for a free gingival graft include?
Surface epithelium and some of the underlying connective tissue
Results in excellent esthetics since the color of the healed tissue often mimics the natural pre existing tissue color precisely what
Subepithelial connective tissue graft
Plastic surgery designed to create a longer clinical crown for a tooth by removing some of the gingiva and usually by removing some alveolar bone from the necks of the teeth
Crown lengthening surgery
A surgical procedure designed to excise and remove some of the gingival tissue
Are dental implants surrounded by cementum and periodontal ligament?
Are implants subject to periodontal disease that can result in the loss of supporting bone just like a natural tooth?
How long should you wait to remove sutures?
After 1 week of healing
How long can most absorbable sutured be left in place?
