|April 2, 2019
Summary
For implant-supported prostheses, cement retention is more cost-effective than screw retention. This study found no significant clinical differences between screw- and cement-retained systems for dental implants.
Area of Science:
- Dental Implantology
- Health Services Research
- Prosthodontics
Background:
- Implant-supported prostheses are crucial for replacing teeth in partially edentulous jaws.
- Choosing between screw-retained and cement-retained systems involves considerations of clinical outcomes and cost-effectiveness.
- Understanding morbidity, incidence, and costs associated with each retention system aids clinical decision-making.
Purpose of the Study:
- To assess the clinical and cost-effectiveness of screw- versus cement-retained implant-supported single crowns and fixed partial dentures.
- To provide evidence for clinicians to make informed treatment choices for partially edentulous patients.
Main Methods:
- Systematic literature search across 10 databases, 4 journal databases, and IADR abstracts.
- Meta-analysis of 92 single crown studies and 40 fixed partial denture studies using random-effects Poisson regression.
- Cost-effectiveness analysis over 15 years using decision trees and ADA survey data for complication costs.
Main Results:
- Meta-analysis indicated no statistically significant difference in clinical outcomes between screw- and cement-retention systems.
- Cost-effectiveness analysis revealed cement retention as the more economical strategy compared to screw retention.
- Probabilistic sensitivity analysis addressed uncertainty in input data parameters.
Conclusions:
- Cement-retained implant-supported prostheses represent a more cost-effective treatment strategy than screw-retained options.
- Clinicians can utilize this evidence to optimize treatment decisions for partially edentulous patients regarding retention systems.

5.4K
Reporting and recording are crucial in data documentation. The timely, thorough, and accurate documentation of facts is essential when recording patient data. Failure to record findings during an assessment or interpretation of a problem will result in loss of information and make the patient document unreliable. The reader is left with general impressions if the information is not specific. A recording is documenting data of the individual's health information in a traceable, secure, and...

1.5K
Here are the steps to accurately measure oral temperature using an electronic thermometer:
Step 1:
Start by practicing proper hand hygiene to prevent the spread of microorganisms.
Step 2:
Take the thermometer out of the charging unit, switch it on, and wait for the ready sign.
Step 3:
Gently slide the probe cover until a click is heard. This simple action prevents cross-contamination and ensures the correct placement of the probe cover.

01:24Hydration of Cement
884
Hydration of cement is a chemical reaction between cement particles and water. This process occurs primarily through two mechanisms: through-solution and topochemical. In the through-solution process, anhydrous compounds dissolve into their constituents, hydrates form in the solution, and then precipitate from the supersaturated solution. The topochemical process involves solid-state reactions at the cement particle surface. The through-solution process dominates the topochemical process at the...

01:17Soundness of Cement
553
The soundness of cement refers to the ability of cement paste to retain its volume after setting. Unsound cement can lead to expansion and structural damage due to the presence of free lime, magnesia, and calcium sulfate. Free lime hydrates very slowly, expanding and causing unsoundness, which is difficult to detect because it intercrystallizes with other compounds. Magnesia also reacts with water, forming crystals that can disrupt the cement's structure. Calcium sulfate can create...

469
Assessing the gastrointestinal (GI) system is a complex process that begins with collecting subjective data. This data, collected through patient interviews, provides crucial insights into the patient's health history, perception patterns, and lifestyle habits, all contributing significantly to GI health.
Health Perception Patterns
Health perception patterns offer valuable insights into a patient's lifestyle habits and how they may impact their GI health. These patterns include:
