Q

The volume density of cortical bone is 3 to 4 times that of which type of bone

A

Cancellous

23
Q

The shape of bone is dependent on several factors

A
  1. ) Any history of trauma or infection
  2. ) length of time since tooth loss occurred
  3. ) loading by removable prostheses
  4. ) systemic conditions such as smoking can influence the quality of bone
24
Q

Both of what must ne considered when planning for implants therapy

A

Shape and quality

25
Q

Whats immediate loading

A

Placement of restoration at the time of the implant surgery

26
Q

Inications for implant therapy

A
  • Pts with a strong gag reflex to eliminate palatal coverage by removable prostheses
  • Long span bridges
  • Free-end removable partial dentures
  • Alternative to periodontally compromised teeth for bridge abutments
  • Hopeless periodonatlly or endodontically involved teeth
  • Orthodontic anchorage
27
Q

Therapy with bisphosphonates increase the risk of what?

A

Jaw osteonecrosis

28
Q

Pts receiving anticoagulant therapy are at risk for what?

A

Hemorrhage during surgical procedures

29
Q

Smoking increases the risk of what?

A

Peri-implantitis and failure

30
Q

What is made up of 2mm long junctional epithelium and a 1mm zone of connective tissue

A

Implant biologic width

31
Q

It exists between the junctional epithelium on the implant abutment and the bone?

A

Connective tissue zone

32
Q

The abutment screw connects the implant abutment to the?

A

Implant fixture

33
Q

The clinical success of implants therapy is assessed by what?

A
  • Radiographic imaging
  • Evaluating implant mobility
  • Observing the surrounding soft tissue
34
Q

Healing for implants is what

A

3 to 6 months

35
Q

The ideal location and angulation of the implant should be consistent with what?

A

Planned prosthetic suprastructures (restorations)

36
Q

The submerged protocol requires two surgical procedures before restorations can be placed on the implants, what are they

A
  • 1st places the implant fixture within the bone

- 2nd 3 to 6 month later to uncover the implant

37
Q

Nonsubmerged protocol is only 1 surgery

A

After the implant placement, the tissues are closed arounf either the transmucosal portion of the implant or the implant or the healing abutment

38
Q

What is jumping distance?

A

Immediate placement of implants into extraction sockets leaves a gap between the implant and the socket wall

39
Q

Healthy implants are?

A

osseointegrated and do not exhibit mobility

40
Q

During probing you should do what?

A

use of plastic probe

avoiding probing during the first 3 months

41
Q

What kind of x-rays are took??

A

Periapical and panoramic are used to assess bone level for implant sites

42
Q

The criteria for implant success includes bone loss not exceeding

A

0.2 mm annually after the 1st year

43
Q

Radiographic follow-up is recommended at

A

6, 12, and 36 month, then every 2 to 3 years there after

44
Q

What is a term for inflammatory reactions in the tissues surrounding an implant

A

Peri-implant disease

45
Q

What is a reversible inflammatory reaction in the soft tissue surrounding an implant

A

Peri-implant mucositis

46
Q

What is inflammatory reactions that affect soft and hard tissues around the implant, leading to the loss of supporting bone

A

Peri-implantitits

47
Q

If this is left untreated, ultimately progress to implant failure

A

Peri-implantitis

48
Q

Peri-implantitis is characterized by what?

A

Increasing probe depths

Bleeding and bone loss

49
Q

This refers to an implant that has lost osseointegration and is no longer an effective prosthetic anchor

A

Failing implant

50
Q

What is the primary microbial etiologic factor in peri-implantitis

A

Plaque biofilm

51
Q

The progression of inflammatory disease around implants appears to be more rapid than around

A

Natural teeth

52
Q

Implants lack connective tissue fiber insertion, what are the attachment mechanism involve?

A

Basal lamina and hemidesmosomes of epithelium

53
Q

Tx for peri-implantitis include

A
  • combination of local or systemic antimicrobial therapy
  • Removal of plaque biofilm and calculus
  • Implant surface decontamination
  • Regeneration of defects
