24

surgical sites should not be probed for at least one week after surgery because the collagen fibers have not had sufficient time to heal to be able to resist the penetration force of the probe

29

these are created from donor bone from the patients own body... may be taken from i gra oral sites such as tori, maxillary tuberosity or bone removed during osteoplasty

Autograft

30

what are indications of access flap procedure?

to treat periodontal pockets aesthetically sensitive areas or where pocket reduction is not destined or indicated

31

this is a type of bone loss in which the interproximal bone is apical to the facial and lingual bone

reverse alveolar bony architecture

32

what is the most predictable method for regenerating lost periodontal tissues??

guided tissue regeneration

33

what types of surgeries do pocket reduction include??

excisional (gingivectomy and gingivoplasty)

incisional (periodontal flap procedures)

34

these extend epically beyond the crest of the bone

infrabony pockets

35

the most common oral site for donor tissue for free gingival graft procedure is the

palate

36

these are created from bone taken from another species such as bovine or cow, porcine or pig bone.

xenografts

37

what has been suggested as the best technique to attempt to cover exposed root surfaces?

lateral pedicle graft

38

if alveolar bone that contains periodontal fibers that support the tooth is removed, this procedure is called...

ostectomy

39

the types of periodontal surgery that increase the predictability for growth of new tissues of the periodontal apparatus are called procedures for

guided tissue regeneration

40

what is root sensitivity following perio surgery caused by?

exposed root surfaces

apically positioned perio flaps

gingival shrinkage during healing

root planing with cementum removal

41

when is periodontal surgery indicated?

to control the progress of periodontal destruction and attachment loss when more conservative non surgical treatment is not successful

42

this includes a variety of periodontal plastic surgery procedures to augment the thickness of keratinized gingival tissues, increase the zone of attached gingiva, improve gingival aesthetics by covering recessed root surfaces, or augment edentulous spaces.

mucogingival surgery

43

periodontal surgery is most successful when pocket depths are between 5 and 9 mm. Indications for periodontal surgery are more effected by measurements of clinical attachment loss than those by pocket depths

both statements are TRUE

44

what are relative contraindications to periodontal surgery?

patient with certain systemic diseases

uncontrolled hypertension

uncontrolled diabetes

certain bleeding disorders

kidney dialysis

what is periodontal regeneration??

the formation of new alveolar bone, new cementum and new periodontal ligament on a tooth root surfaces that was previously diseased

47

what does guided tissue regeneration permit??

the healing cells to proliferate from bone and periodontal ligament rather than epithelium to and from bone and periodontal ligament rather than epithelium to more reliably gain new attachment to the tooth more reliably
