What does extrusion mean in medical terms?
(eks-trū’zhŭn), 1. A thrusting or forcing out of a normal position. 2. The overeruption or migration of a tooth beyond its normal occlusal position.
Why is extrusion used?
Extrusion is a technique where molten polymer is forced through a die and is used to produce components of a fixed cross-sectional area such as tubes and rods.
What is an extruded tooth?
An extrusion is defined as a displacement of a tooth out of its socket. This can make the tooth appear to be elongated, and it can wiggle excessively as a result. The tooth can be very sensitive, and often, the extrusion can cause intense pain.
What is extrude in computer?
In computer graphics, extrusion refers to rendering of a three-dimensional (3D) object from a Two-Dimensional one by essentially grabbing a line and stretching it out along a new third axis, accomplished in the same manner as a square is turned into a cube.
What does the Extrude tool do?
Formally, the extrude tool can be defined as a tool that duplicates the selected vertices, edges, and faces, connecting them to the original model in series of the original vertices, edges, or faces. This tool is useful for creating more vertices for better and more specific modeling.
What is extrude in multimedia?
Extruding a spline makes an exact copy of the spline a certain distance away from the original and then creates a surface between the two.
Where is extrude in blender?
Extrude your selection in one of several ways: Use the E hotkey. Left-click Add→Extrude Region in the Tools tab of the Tool Shelf. Choose Mesh→Extrude→Extrude Region from the menu in the 3D View’s header.
Can an extruded disc heal on its own?
The good news is that in most cases — 90% of the time — pain caused by a herniated disc will go away on its own within six months. Initially, your doctor will likely recommend that you take an over-the-counter pain reliever and limit activities that cause pain or discomfort.
Does disc extrusion require surgery?
For minor cases of disc extrusion, surgery may not be necessary. Many extruded discs heal on their own. Nevertheless, treatment for pain that often accompanies disc extrusion may be necessary for some patients. Treatments usually include pain medication, steroid injections, nerve blocks and more.
What are the types of extrusion?

What is an extruded product?
Extrusion is a mechanical process in which certain materials are forced, under pressure, through a die opening to create products of a desired shape, size, and/or texture. Legume flours are often used as the basis for formulations that are extruded in low pressure systems.
What is an example of extrusion?
Everyday examples of extrusion can be seen when toothpaste is squeezed out of a tube, icing is pushed out of an icing bag and “Playdo” shapes are made. Extrusion moulding of plastics is used to make any long shape that has a constant cross section. Perhaps most common plastic extruded is PVC.

How long does tooth extrusion take?
The time required for extrusion varies depending on the amount of tissue to be extruded. Simon et al. [26], suggested 1 to 3 weeks for the activation and 8 to 12 weeks for the stabilization of teeth in the final position.
What is a molar extraction?
A tooth extraction is the permanent removal of a tooth from its socket and may be done manually using forceps or surgically.

What is Revolve Extrude command?
The Revolve command is conceptually the same as the Extrude command: you have a 2D base shape but instead of extruding it, it is revolved around a specified axis and with a given angle.
What is use of Revolve command?
Creates a 3D solid or surface by sweeping an object around an axis. Open profiles create surfaces and closed profiles can create either a solid or a surface. The MOde option controls is a solid of surface is created.
What is Extrude in Solidworks?
