The CAD/CAM Compound Prosthesis: Digital Workflow for Fabricating Cement-Retained Zirconia Prosthesis Over
The International Journal of Periodontics & Restorative Dentistry
|December 14, 2018
Summary
This study presents a computer-assisted design/computer-assisted manufactured (CAD/CAM) approach for creating a hybrid dental prosthesis. The method combines cement-retained zirconia for the superstructure and screw-retained titanium bars for the substructure, ensuring esthetics and retrievability.
Area of Science:
- * Dental Prosthodontics
- * Digital Dentistry
- * Implantology
Background:
- * Explores the application of computer-assisted design/computer-assisted manufacturing (CAD/CAM) in fabricating complex dental prostheses.
- * Details a clinical case report focusing on restoring both the maxillary and mandibular arches with implant-supported prostheses.
Observation:
- * A diagnostic wax pattern was utilized to evaluate esthetics, contours, and occlusion.
- * A milled polymethyl methacrylate (PMMA) interim prosthesis was fabricated for intraoral verification.
- * The interim prosthesis was scanned to design the substructure for the definitive restoration.
Findings:
- * Eight maxillary implants were restored using a combined prosthesis design concept.
- * The mandibular arch featured a screw-retained implant-supported zirconia fixed prosthesis.
- * A definitive cement-retained milled zirconia prosthesis was fabricated over three screw-retained milled titanium bars.
Implications:
- * The CAD/CAM approach facilitates the creation of esthetic, functional, and retrievable complete-arch restorations.
- * This technique integrates milled titanium substructures with a cement-retained zirconia superstructure.
- * Successful intraoral confirmation and temporary cementation ensure long-term viability and patient satisfaction.

C4 Pathway and CAM
49.2K
Most plants use the C3 pathway for carbon fixation. However, some plants, such as sugar cane, corn, and cacti that grow in hot conditions, use alternative pathways to fix carbon and conserve energy loss due to photorespiration. Photorespiration is the process that occurs when the oxygen concentration is high. Under such conditions, the rubisco enzyme in the Calvin cycle binds O2 instead of CO2, which halts photosynthesis and consumes energy.

Bar Graph
22.2K
A bar graph is also called a bar chart and consists of bars that are separated from each other. It either uses horizontal or vertical bars to show comparisons among categories. The bars can be rectangles, or they can be rectangular boxes (used in three-dimensional plots). One axis of the graph represents the specific categories being compared, and the other axis shows a discrete value. In this graph, the length of the bar for each category is proportional to the number or percent of individuals...

Hydration of Cement
920
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...

Soundness of Cement
565
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...

Multiple Bar Graph
9.3K
As the name suggests, a multiple bar graph is the same as a bar graph but has multiple bars to depict relationships between different data values. One can include as many parameters as possible. However, each parameter must have the same unit of measurement.
Each bar or column in the multiple bar graph represents a data value. These graphs are used primarily in interrelating two or more sets of data. The categories of different kinds of data are listed along the horizontal or x-axis, whereas...

Screw: Problem Solving
701
In mechanical engineering, the interaction between a threaded screw shaft and a plate gear involves analyzing the resisting torque on the plate gear that can be overpowered when a specific torsional moment is applied to the shaft. To better comprehend this concept, consider a generic situation with a threaded screw shaft with a given mean radius and lead and a plate gear with a specified mean radius. The coefficient of static friction between the screw and gear is also provided.
