Exam 4 CH 33 The Patient with Dental Implants Flashcards
Term;Segment connecting the submerged implant body to the prosthetic component. The abutment enters the oral cavity providing a platform for attaching crowns or bridges?
Abutment
Term; capable of existing in harmony with the surrounding biologic environment?
Biocompatible
Term; Layers of fibrous connective tissue between the implant and surrounding bone. Also called fibrous integration; indicative of failed osseointegration?
Fibrous encapsulation
Term;A procedure that attempts to regenerate lost periodontal structures?
Guided tissue regeneration
Term; The direct attachment or connection of osseous tissue to an inert alloplastic material without intervening connective tissue?
Osseointegration
Term; Destructive inflammatory process of the periodontal tissues around an implant characterized by progressive bone loss in addition to soft tissue inflammation with hemorrhage and/or exude; similar to periodontitis in a natural tooth?
Peri-implantitis
Term; A common titanium alloy (Ti-6A1-4V) used for dental implants that contains 6% aluminum to increase strength and decrease weight and 4% vanadium to prevent corrosion?
Titanium alloy
What is the most common dental implant used?
Endosseous (Endosteal) Implant
T/F Mobility is the #1 indicator fo implant failure?
True
Biofilm around the titanium abutment should be removed with what?
Gauze strips
Reversible inflammation of the periodontal tissues around an implant with no subsequent bone loss; similar to gingivitis in a natural tooth is?
Peri-implant mucositis
What implant is placed fully within the bone?
Endosseous
What is the structural and functional union between implant and bone?
Osseointegration
The risk for implant in smokers is?
twice as high as in nonsmokers
T/F Bone will resorb when teeth are removed. Dental implants preserve surrounding bone through function.
Both statements are true
Implants may be indicated for patients who:
have an edentulous maxilla
All of he following interdental implements could be recommended to a patient with implants ?
- Synthetic yarn
- folded strip of gauze
- floss threader
What type of FL2 is recommended for at home use in patients with dental implants?
Natural Sodium FL2
All of the following are characteristics of fibrous encapsulation?
- Failure of osseointegration
- Implant mobility
- Infusion of connective tissue cells between implant and bone
Which type of implants are indicated when the patient has an atrophic in edentulous mandible or congenital or traumatic deformity of the mandible?
Transosseous (Transosteal)
What implant is most commonly used for dentures?
Transosseous (Transosteal)
A dental implant that penetrates both cortical plates and passes through the full thickness of the alveolar bone. It is also known as a mandibular staple implant or staple bone implant?
Transosseous (Transosteal)
What are Subperiosteal dental implants made of?
Titanium or vitalism
Custom-fabricated framework of metal that rests over the bone of the mandible or maxilla, under the periosteum: Complete arch or unilateral?
Subperiosteal
What irrigation should be used on a patient with implants?
Chlorhexadine
What dental instruments should be used with implants?
ALWAYS USE PLASTIC INSTRUMENTS!
Smooth, plastic probe with a rounded end
T/F A patient with implants should avoid acidic FL2
True
What does a healthy implant show?
- No pain or discomfort reported by patient
- No Mobility
- No bone loss or periimplant radiolucency in X-ray
- No clinical signs of periimplantitis.
- Gingiva should be firm with no edema
Which implant is primarily plasma-sprayed titanium?
Endosseous (Endosteal)
Contraindications for implant success?
-Pregnancy
-Debilitation
-Uncontrolled diabetes
-Alcoholism or heavy intake
-Substance abuse
-Immunosuppressive disease or medication
-Anticoagulant medication
-Psychosis or paranoia
Recent radiation therapy the affect part of oral cavity
T/F It is recommended that a patient cease smoking at least 1 week before surgery and at 2 months after implant placement or after its healed.
True
What patients are a good candidate for implants?
Patients with no systemic conditions that will interfere with healing or implant acceptance
T/F Wolff’s Law (1892) States bone loss is laid down in areas of greatest stress and is resorbed in areas where it is not stressed.
True
Failure of ossointegration is known as?
Fibrous Encapsulation
Indications of successful placement of the implant is known as?
Osseointegration
Refers to the infusion of connective tissue cells between the implant body and surrounding bone?
Fibrous Encapsulation
Refers to direct structural and functional union between the implant and healthy living bone?
Osseointegration
T/F Biofilm microorganisms around implants with healthy permucosal tissue have been shown to be similar to the flora around natural teeth.
True
OH Care for implants and natural teeth?
- Use soft tooth brush, manual or powered
- Use spongy floss with built in threader
- Use smooth plastic coated wires for interdental brushes
- Synthetic yarn or gauze to clean abutments
- end-tuft brush with soft filaments to clean linguals/palatal embrasures
- Round, wooden toothpicks used in plastic handles for proximal tooth surfaces
Reversible bacterial infection in the soft tissue similar to gingivitis. Mild color change with bleeding may be present is known as?
Periimpant Problems
*Initial Stage-Mucositis
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 is known as?
*Secondary Stage Periimplantitis
Inflammation present but no mobility. Consult surgeon if no response to treatment in 2 weeks is known as?
Alining implant
Inflammation present. Bone loss has occurred and continues. Mobility faintly noticeable is known as?
Failing implant
Evident mobility. Radiographic changes are evident, often showing a vertical bony defect. Refer patient immediately back to surgeon is known as?
Failed implant
