Unit 10 - Peri-Implant Health and Disease Flashcards
What is a nonbiologic device surgically inserted into the jawbone to replace a missing tooth and/or provide support for a prosthetic denture?
An implant
How many Americans have dental implants?
Over 3 million
Clients with dentures chew at ___% efficiency than those with natural dentition
25%
Implants increasing chewing efficiency to ___%
96%
What is are the componants of the dental implant system?
Implant crown
Abutment post
Implant body
What is the root of the implant that is surgically placed into the living alveolar bone?
Implant body
What is the titanium post that attachs to the implant body?
Abutment
What is the esthetic benefit of zirconia over titanium?
Zirconia is more esthetically pleasing and will not shine easily through thin gingiva
What are the advantages of a titanium implant?
Lightweight
Biocomatible
Doesn’t corrode or rust
Poor heat conductor
What is the disadvantage of a titanium implant?
Softer than other metals, easily scratched by non-titanium metal instruments
What are the soft tissues surrounds the dental implant called?
Peri-implant tissues
Implants are successful when:
Absence of mobility of the implant
No discomfort or pain
No increase in bone loss
Less than 0.2mm of bone loss annually after the first year of function
True or Fales: gingival sulcus depths should be 1.3mm - 3.8mm
True
What are the names of the tissues surrounding a dental implant?
JE
Connective tissue
Alveolar bone
What is characterized by an absence of erythema, BOP, swelling, and suppuration?
Peri-implant health
What does peri-implant tissue inflammation look like?
Plaque deposits on implants
Can result in inflammation of soft tissues around the implant
As disease progresses, partial or total loss of osseointegration occurs
What are the two forms of peri-implant disease?
Peri-implant mucositis
Peri-implantitis
What is peri-implant mucositis?
Plaque induced gingivitis in tissues surrounding the implant
What is peri-implantitis?
Periodontitis in tissues surrounding osseointegrated implant, resulting in bone loss
Is peri-implant mucositis reversible?
Yes
Peri-implant mucositis occurs in ___% of clients and ____% of implant sites
80%
50%
Signs of peri-implant mucositis
Red tissues
Swelling
Bleeding
Increased probing depths
What is peri-implantitis?
Periodontits affecting soft and hard tissues surrounding a functioning osseointegrated implant
True or False: Peri-implantitis may progress in a nonlinear and accelerating pattern
True
What is the prevalance range for peri-implantitis?
6.61% - 47%
What are the disagnosis requirements for peri-implantitis?
Signs of inflammatin
Presence of bleeding and supporation upon probing
Increased probing depths
Progessive bone loss as seen on radiographs
When does an implant become mobile due to peridontal disease?
At the final stages of peri-implantitis
Both forms of peri-implant disease share common etiology. They are:
Polymicrobial bacterial infection
Biomechanical factors
True or False: Rate of destruction is slower in peri-implant tissues than in a natural dentition.
False. Rate of destruction is more rapid in peri-implant tissues than in a natural dentition.
What are the risk factors for implant failure?
History of previous periodontal disease
Poor plaque biofilm control
Smoking
Residual cement
Biomechanical overload
Clinical signs in soft tissue of a failing implant:
Peri-implant pocket
Bleeding
Suppuration
Possible swelling
Pain usually not present
Mobility
Treatment modalities for failing implants
Nonsurgical periodontal instrumentation
Use of antiseptics
Loacl/systemic antibiotics
Flap surgery
Subgingival air polishing with glycine powder
Important data collecting procedures for peri-implant health and disease
Oral hygiene assessment/plaque control
Probing
Assess CAL
Assess bleeding
Assess for suppuration
X-rays
Factors that contribute to hard tissue deficiencies:
Extraction trauma
Lack of support from periodontitis
Endo infections
Thin buccal bone plates
Systemic diseases impairing normal bone remodeling
Injury and pneumatization of the sinus
Goals for implant maintenance
Maintenance of alveolar bone support
Control of inflammation
Maintenance of health functional implant
Maintenance of health and function periodontium surrounding neighbouring teeth
Questions to ask patient with implants:
Are you able to clean around implant neck?
Do you have enough cleaning aids?
Are you satisifed with implant function?
Are you satisfied with implant appearance?
Do you feel any parts of implant are loose?
Do your gums around implant bleed?
Do you notice a bad taste coming from the implant?
Have you noticed any changes regarding the implant?
How often should patients with an implant be advised to return for recall?
At least every 6 months.
Every 3 months for at least the first year
