Implant Failure Risk
Multivariate Clinical Success Analysis

Understanding Implant Success Factors
Dental implant success is not guaranteed and relies on a complex interplay of patient biology and surgical execution. The primary causes of failure are split into **Early Failure** (lack of osseointegration) and **Late Failure** (peri-implantitis or mechanical overload).
How does smoking affect implants?
Nicotine causes vasoconstriction, which impairs blood flow to the healing bone. Studies show smokers have a **2 to 3 times higher risk** of implant failure compared to non-smokers.
Why is Type IV bone risky?
Type IV bone (often found in the posterior maxilla) has a thin cortex and low-density trabeculae, providing poor primary stability for the implant fixture.
