A

immediate placement of endosteal inplants

34
Q

36
Q

what irrigation do we use for a pt with implants

A

Chlorhexadine can be used as a rinse or with an oral irrigator

37
Q

What fluoride should be used for a pt with implants

A

Neutral sodium fluoride. Avoid acidic fluoride

38
Q

if a pt has natural teeth and implants

A

they should use an at-home fluoride treatment.

39
Q

biofilm around implant

A

Biofilm microorganisms around implants with healthY tissue have been shown to be similar to the flora around natural teeth.

40
Q

Probe used for implants

A

Use a smooth, plastic probe with a round end

41
Q

refers to the infusion of connective tissue cells between the implant body and surrounding bone. It indicates failure of osseointegration. Mobility is evident.

A

Fibrous encapsulation

42
Q

reversible bacterial infection in the soft tissue similar to gingivitis. Mild color change with bleeding may be present.

A

Initial Stage-Mucositis

43
Q

Inflammation has reached the level of the bone. Edema or hemorrhage is present in the surrounding tissues. Exudate may or may not be present, and probing depths are increased.

A

Secondary Stage Periimplantitis

44
Q

inflammation present but no mobility. Consult surgeon if no response to tx in 2 weeks.

A

Ailing Implant .

45
Q

inflammation present. Bone loss has occurred and continues. Mobility faintly noticeable.

A

Failing implant

46
Q

Evident mobility. Radiographic changes are evident, often showing a vertical bony defect. Refer pt. immediately back to surgeon.

A

Failed implant

47
Q

dental hygiene considerations when cleaning an implatn

A

Always use plastic instruments!
Do not use an ultrasonic
Confine manual instrumentation to the prosthesis and supragingival area of the abutment
Only non-abrasive prophy paste is used if any at all

48
Q

a healthy implant shows

A

No pain or discomfort reported by the patient
No mobility
No bone loss or periimplant radiolucency in a radiograph
No clinical signs of periimplantitis. Gingiva should be firm with no edema.
No bleeding or increased probing depths on gentle probing performed with a rounded, smooth plastic probe.

49
Q

a pt that is a good candidate for dental implants will have

A

no systemic conditions that interfere with healing or implant acceptance

50
Q
