Dental Implants Osseointegration & Healing 3

Question 1

Early (premature) implant failure is defined as failure occurring:

Accepted Answer

Before or shortly after loading, typically within the first year

Answer

Early failure occurs before functional osseointegration is established or shortly after loading, usually due to infection, overload, or inadequate bone quality.

Question 2

Late implant failure is most commonly associated with:

Accepted Answer

Peri-implantitis and cumulative bone loss over time

Answer

Late failures typically result from progressive peri-implant bone loss due to peri-implantitis, occlusal overload, or systemic disease progression.

Question 3

Which radiographic sign indicates successful osseointegration on a periapical radiograph?

Accepted Answer

Direct contact between the implant threads and bone without radiolucency

Answer

Successful osseointegration appears radiographically as direct crestal bone contact with the implant surface and absence of peri-implant radiolucency.

Question 4

Hyperbaric oxygen (HBO) therapy in implant dentistry may be used to:

Accepted Answer

Enhance healing in previously irradiated bone or compromised healing sites

Answer

HBO therapy increases tissue oxygen tension, promoting angiogenesis and osteogenesis in hypoxic, irradiated, or poorly vascularized bone environments.

Question 5

The biologic width around a dental implant consists of:

Accepted Answer

Junctional epithelium and connective tissue attachment forming the peri-implant seal

Answer

The peri-implant biologic width includes the sulcular epithelium, junctional epithelium, and supracrestal connective tissue that protect the underlying bone.
