27
Q

Up to 6 weeks

A

Callus formation and lamellar compaction within woven bone

-shrinkage may have temp decrease in implant stability

28
Q

Jumping distance concept

A

The distance that can be filled by new bone between the implant and the remaining host bone

29
Q

Ideal tolerable jumping distance

A

20-40 um

Larger does not heal well

30
Q

Accepted healing period for osseointegration

A

6 months maxilla

3 months mandible

31
Q

____ is poor in blood supply

A

Cortical bone

32
Q

Implant surface we use

A

SLA or HA/TCP

HA has issues with resorption over time

33
Q

An implant should be surrounded with a minimum of

A

1mm of alveolar bone thickness

34
Q

Minimum bone thickness between 2 implants

A

3 mm

Implant to implant

35
Q

Minimum bone thickness between an implant and a tooth should be

A

4 mm

From root surface to implant

36
Q

Coronal part of an implant should be placed

A

5 mm apical to adjacent CEJ

37
Q

Maximum implant angle

A

20

38
Q

transmucosal attachment

A

Barrier epithelium 2 mm

Zone of connective tissue 1-1.5mm high

Collagen fiber bundles parallel to implant surface

39
Q

Zone that is adjacent to I place the surface is rich in _____but poor in ______

A

Fibroblasts

Blood vessels

40
Q

Zone that is in lateral direction and contours with the first zone has

A

Fewer fibroblast but it is rich in collagen fibers and blood vessels

41
Q

Blood supply coming only from

A

Superior periosteal blood vessels

42
Q

Two stage implant placement

A

Submerged tech

43
Q

One stage implant placement

A

Non-submerged

44
Q

Microgap

A

Micro space that exists between implant fixture and abutment

-usually at alveolar crest

45
Q

Optimum function

A

20 teeth needed

46
Q

Criteria for successful implant

A

The implant is immobile
Absence of peri-implant radiolucency
Absence of pain, infection, neuropathy or parathesia
After 1st year in function,

47
Q

Ailing Implant

A

Peri-implant mucosisitis

Peri-implantitis

48
Q

Failing Implant

A

Peri-Impantitis

49
Q

Failed Implant

A

Peri-implantitis with mobility and complete loss of of osseointegration

50
Q

Peri-implant mucositits

A

Reversible inflammation of the mucosa surrounding the implant

51
Q

Peri-implantitis

A

Inflammatory reactions associated with loss of supporting one around an implant IN FUNCTION

52
Q

Mucositis almost always

A

Develops into peri-implantitis

53
Q

At the time of placement if you placed implant 6mm

A

Apical to CEJ 90% will get implantitis

-build up with bone

54
Q

Any form of inflammation on teeth surrounding implant

A

Peri-implantitis

55
Q

Peri-implantitis are characterized by

A

Presence of numerous neutrophils in the tissue surrounding the implant
-not seen in periodontitis

56
Q

In peri-implantitis there is direct contact between

A

Plaque on the implant surface and inflamed connective tissue
-not seen in periodontitis

57
Q

Implants and teeth may have

A

Different microbiology which can impact treatment

58
Q

______is a Secondary etiologic all factor of periodontal disease

A

Occlusal trauma

59
Q

Occlusal trauma is a _______ etiological factor for peri-implant Disease

A

Primary

60
Q

Class 1 Peri-implantitis

A

Slight horozontal bone with loss minimal peri-implant defects

61
Q

Class 2 Peri-implantitis

A

Moderate horizontal bone loss with isolated vertical defects

62
Q

Class 3 Peri-implantitis

A

Moderate to advanced horizontal bone loss with broad circular bony defects

63
Q

Class 4 Peri-implantitis

A

Advanced horizontal bone loss with broad circumferential vertical defects as well as loss of the oral and or vestibular bony wall

64
Q

Class 1 treatment

A

Reduce pocket
Reposition flaps at a bone edge
Decontaminate implant
Omplantoplasty if threads exposed

65
Q

Class 2 treatment

A

Reposition but more apical than class 1 so more Implant is exposed
If 3 or more walls GTR techniques to restore
One or 2 walls osteoplasty

66
Q

Class 3 and 4 Treatment

A

In peri-implantitis the presence of vertical defects almost always requires the use of GTR techniques
