Q

21
Q

internal bevel incision

A

surgical scalpel blade enters the marginal gingiva, but is not placed directly into the sulcus - enters gingiva approx 0.5 to 1.0 mm away from the margin and follows the general contour of the scalloped marginal gingiva

22
Q

vertical incisions

A

run perpendicular or obliquely to the gingival margin in an apico-occlusal direction

23
Q

flap for access

A

used to provide access to the tooth roots for improved root preparation

24
Q

open flap debridement or open curettage

A

a periodontal surgical procedure quite similar in concept and execution to flap for access surgery

25
Q

osseous resective surgery

A

term used to describe periodontal surgery employed to correct many of the irregular deformities of the alveolar bone that often results from periodontitis

26
Q

ostectomy

A

removal of tooth-supporting bone, alveolar bone proper

27
Q

osteoplasty

A

reshaping the surface of alveolar bone without actually removing any of the tooth-supporting bone

28
Q

apically positioned flap with osseous resective surgery

A

a periodontal surgical procedure involving a combination of a displaced flap plus resective osseous surgery

29
Q

bone replacement graft

A

a broad class of implantable materials that are used in medicine and dentistry to induce the body to augment and/or regenerate tissue that has been lost as a result of disease, trauma, or injury

30
Q

osteogenesis

A

the formation of new bone by viable, living cells that are contained in the graft material

31
Q

osteoinduction

A

a chemical process whereby molecules contained in the graft material - known as bone morphogenetic proteins (BMPs) - have the ability to recruit and attract host bone-forming cells (osteoblasts) to the site of implantation to form new bone

32
Q

osteoconduction

A

a physical, passive process whereby the graft material itself acts as a scaffold for host bone-forming cells to migrate, attach, and grow on

33
Q

autografts

A

bone harvested from patient’s own body

34
Q

allografts

A

bone harvested from another human

35
Q

xenograft

A

bone harvested from another species

36
Q

alloplast

A

synthetic (man-made) bone-like material

37
Q

guided tissue regeneration

A

a periodontal surgical procedure employed to encourage regeneration of lost periodontal structures by “guiding” the movement of progenitor cells toward the treated root surface while excluding the migration of the gingival epithelial cells and fibroblasts

38
Q

periodontal plastic surgery

A

periodontal surgical procedures that are directed toward correcting or eliminating deformities associated with the gingiva or alveolar mucosa

39
Q

mucogingival surgery

A

periodontal surgical procedures that correct any deformity associate with the gingiva and mucosa

40
Q

free soft tissue autograft or free gingival graft

A

a type of periodontal plastic surgery that was one of the first procedures used to augment the width of attached gingiva

41
Q

subepithelial connective tissue graft

A

a periodontal plastic surgical procedure that can also be used to augment the width of attached gingiva and to cover areas of gingival recession

42
Q

laterally positioned flap

A

a periodontal plastic surgery technique that can be used to cover root surfaces with gingiva in isolated sites of gingival recession

43
Q

coronally positioned flap

A

a periodontal plastic surgical procedure that can be used to repair gingival recession if the recession is not severe

44
Q

semilunar coronally repositioned flap

A

a procedure to cover gingival recession where the recession is not far advanced and where the keratinized tissues have an adequate thickness

45
Q

frenectomy

A

a periodontal plastic surgical procedure that results in removal of a frenum, including removal of the attachment of the frenum to bone

46
Q

crown lengthening surgery

A

a periodontal plastic surgery designed to create a longer clinical crown for a tooth by removing some of the gingiva and usually some alveolar bone from the necks of the teeth

47
Q

functional crown lengthening

A

a periodontal plastic surgery performed on a tooth where the remaining tooth structure is inadequate to support a needed restoration

48
Q

esthetic crown lengthening

A

a periodontal plastic surgery performed on teeth to improve the appearance of the teeth where there is excessive gingiva or a “gummy smile”

49
Q

gingivectomy

A

a surgical procedure designed to excise and to remove some of the gingival tissue

50
Q

gingivoplasty

A

a surgical procedure that simply reshapes the surface of the gingiva to create a natural form and contour to the gingiva

51
Q

periodontal microsurgery

A

a periodontal surgery performed with the aid of a surgical microscope
