25
1 week after implantation
Reparative macrophage and undifferentiated mesenchymal cells | Modeling at the apical trabecular region and at the furcation sites of a screw shaped implant
26
2 weeks after implantation
New bone formation can be detected at the furcation sites of the implant surface
27
Up to 6 weeks
Callus formation and lamellar compaction within woven bone | -shrinkage may have temp decrease in implant stability
28
Jumping distance concept
The distance that can be filled by new bone between the implant and the remaining host bone
29
Ideal tolerable jumping distance
20-40 um Larger does not heal well
30
Accepted healing period for osseointegration
6 months maxilla 3 months mandible
31
____ is poor in blood supply
Cortical bone
32
Implant surface we use
SLA or HA/TCP HA has issues with resorption over time
33
An implant should be surrounded with a minimum of
1mm of alveolar bone thickness
34
Minimum bone thickness between 2 implants
3 mm Implant to implant
35
Minimum bone thickness between an implant and a tooth should be
4 mm From root surface to implant
36
Coronal part of an implant should be placed
5 mm apical to adjacent CEJ
37
Maximum implant angle
20
38
transmucosal attachment
Barrier epithelium 2 mm Zone of connective tissue 1-1.5mm high Collagen fiber bundles parallel to implant surface
39
Zone that is adjacent to I place the surface is rich in _____but poor in ______
Fibroblasts Blood vessels
40
Zone that is in lateral direction and contours with the first zone has
Fewer fibroblast but it is rich in collagen fibers and blood vessels
41
Blood supply coming only from
Superior periosteal blood vessels
42
Two stage implant placement
Submerged tech
43
One stage implant placement
Non-submerged
44
Microgap
Micro space that exists between implant fixture and abutment -usually at alveolar crest
45
Optimum function
20 teeth needed
46
Criteria for successful implant
The implant is immobile Absence of peri-implant radiolucency Absence of pain, infection, neuropathy or parathesia After 1st year in function,
47
Ailing Implant
Peri-implant mucosisitis | Peri-implantitis
48
Failing Implant
Peri-Impantitis
49
Failed Implant
Peri-implantitis with mobility and complete loss of of osseointegration
50
Peri-implant mucositits
Reversible inflammation of the mucosa surrounding the implant
51
Peri-implantitis
Inflammatory reactions associated with loss of supporting one around an implant IN FUNCTION
52
Mucositis almost always
Develops into peri-implantitis
53
At the time of placement if you placed implant 6mm
Apical to CEJ 90% will get implantitis | -build up with bone
54
Any form of inflammation on teeth surrounding implant
Peri-implantitis
55
Peri-implantitis are characterized by
Presence of numerous neutrophils in the tissue surrounding the implant -not seen in periodontitis
56
In peri-implantitis there is direct contact between
Plaque on the implant surface and inflamed connective tissue -not seen in periodontitis
57
Implants and teeth may have
Different microbiology which can impact treatment
58
______is a Secondary etiologic all factor of periodontal disease
Occlusal trauma
59
Occlusal trauma is a _______ etiological factor for peri-implant Disease
Primary
60
Class 1 Peri-implantitis
Slight horozontal bone with loss minimal peri-implant defects
61
Class 2 Peri-implantitis
Moderate horizontal bone loss with isolated vertical defects
62
Class 3 Peri-implantitis
Moderate to advanced horizontal bone loss with broad circular bony defects
63
Class 4 Peri-implantitis
Advanced horizontal bone loss with broad circumferential vertical defects as well as loss of the oral and or vestibular bony wall
64
Class 1 treatment
Reduce pocket Reposition flaps at a bone edge Decontaminate implant Omplantoplasty if threads exposed
65
Class 2 treatment
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
Class 3 and 4 Treatment
In peri-implantitis the presence of vertical defects almost always requires the use of GTR techniques
