Summary
Periodontitis grading, not staging, significantly impacts long-term dental implant survival in compromised patients. Higher grades increase implant loss risk, emphasizing careful treatment planning for successful outcomes.
Area of Science:
- Periodontology
- Dental Implantology
- Oral Health Research
Background:
- Periodontitis is a prevalent inflammatory condition affecting the tissues supporting teeth.
- Periodontally compromised patients often seek dental implants for tooth replacement.
- Understanding risk factors for implant survival in these patients is crucial.
Purpose of the Study:
- To evaluate the association between periodontitis stage and grade and long-term dental implant survival.
- To identify specific periodontitis classifications that pose a risk to implant longevity.
Main Methods:
- Retrospective analysis of 1106 implants in 362 periodontitis patients.
- Assessment of periodontitis stage and grade based on clinical and radiographic data.
- Kaplan-Meier survival analysis and Cox regression modeling over a median follow-up of 85.5 months.
Main Results:
- Overall implant failure rate was 7.69%, with 50% occurring within six months (osseointegration failure).
- Cumulative survival rates were 95.8% (5 years), 91.1% (10 years), and 82.6% (15 years).
- Periodontitis grading, specifically grade C, was significantly associated with increased implant loss risk (HR=2.78).
Conclusions:
- Periodontitis grading is a significant predictor of long-term dental implant survival.
- Clinicians and patients must consider periodontitis severity during treatment planning to mitigate risks.
- Despite risks, dental implants remain a viable therapeutic option for periodontitis patients.

01:18Survival Curves
751
Survival curves are graphical representations that depict the survival experience of a population over time, offering an intuitive way to track the proportion of individuals who remain event-free at each time point. These curves are widely used in fields such as medicine, public health, and reliability engineering to visualize and compare survival probabilities across different groups or conditions.

01:19Survival Tree
439
Survival trees are a non-parametric method used in survival analysis to model the relationship between a set of covariates and the time until an event of interest occurs, often referred to as the "time-to-event" or "survival time." This method is particularly useful when dealing with censored data, where the event has not occurred for some individuals by the end of the study period, or when the exact time of the event is unknown.

33.4K
Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.

01:18Introduction To Survival Analysis
844
Survival analysis is a statistical method used to study time-to-event data, where the "event" might represent outcomes like death, disease relapse, system failure, or recovery. A unique feature of survival data is censoring, which occurs when the event of interest has not been observed for some individuals during the study period. This requires specialized techniques to handle incomplete data effectively.

619
Survival analysis is a cornerstone of medical research, used to evaluate the time until an event of interest occurs, such as death, disease recurrence, or recovery. Unlike standard statistical methods, survival analysis is particularly adept at handling censored data—instances where the event has not occurred for some participants by the end of the study or remains unobserved. To address these unique challenges, specialized techniques like the Kaplan-Meier estimator, log-rank test, and...

01:09Truncation in Survival Analysis
643
Truncation in survival analysis refers to the exclusion of individuals or events from the dataset based on specific criteria related to the time of the event. This exclusion can happen in two primary forms: left truncation and right truncation.
Left truncation occurs when individuals who experienced the event of interest before a certain time are not included in the study. This is often due to a "delayed entry" into the study where only those who survive until a certain entry point are...
