Where do you put rest seats?
Rests should always be located on properly prepared tooth surfaces. The prepared surface of an abutment to receive the rest is called the rest seat. Rests are designated by the surface of the tooth prepared to receive them (occlusal rest, lingual rest, and incisal rest).

What is combination clasp?
A combination clasp is a circumferential retainer for a removable dental prosthesis that has a cast reciprocal arm and a wrought wire retentive clasp (GPT8). It consists of a wrought wire retentive arm and a cast reciprocal arm. The combination of a wrought alloy and cast alloy gives it the name 'combination clasp'.
What is Fulcrum line in RPD?
A fulcrum line is an imaginary line around which an RPD will tend to rotate. Fulcrum lines may be in the horizontal, frontal or vertical plane. Indirect retainers provide resistance to rotational movement of a distal extension RPD away from the denture bearing tissues around the retentive fulcrum line (Figure 2).
What is a pier abutment in RPD?
Pier abutment is an intermediate abutment for a fixed dental prosthesis. Moreover, an intermediate abutment is a natural tooth located between terminal abutments that serve to support a fixed/removable prosthesis.
What does REST in REST API stand for?
Representational State TransferRepresentational State Transfer (REST) is a software architecture that imposes conditions on how an API should work. REST was initially created as a guideline to manage communication on a complex network like the internet.

6: Rests and Rest Seats
The capacity for teeth to resist functional forces and remain stable over time is provided through their sophisticated support mechanisms. Studies have shown that displacement and recovery following loading are far better for natural teeth than for oral mucosa.
Role of Rests in Control of Prosthesis Movement
Appropriate use of teeth requires consideration as to how best to engage teeth for the supportive qualities they provide. Because the most effective resistance can be provided if the tooth is stressed along its long axis, the prosthesis framework should engage the tooth in a manner that encourages axial loading.
Form of the Occlusal Rest and Rest Seat
1. The outline form of an occlusal rest seat should be a rounded triangular shape with the apex toward the center of the occlusal surface ( Figure 6-2 ).
Extended Occlusal Rest
In Kennedy Class II, modification 1, and Kennedy Class III situations in which the most posterior abutment is a mesially tipped molar, an extended occlusal rest should be designed and prepared to minimize further tipping of the abutment and to ensure that the forces are directed down the long axis of the abutment.

How to pin a strip on a cover?
Pin the strip and cover together starting at the matching side seams. Flip the cover right side out so that the seams are hidden, and leave the strip inside out so that the seams are visible. Locate the seams on the cover and the strip. Line up 1 seam of the strip with 1 seam of the cover.
How to sew a cover with a strip?
Line up 1 seam of the strip with 1 seam of the cover. Position the strip along the outside of the bottom of the cover so that their edges are aligned. Place pins through the strip and cover, starting at the seam. Insert the pins perpendicular to the edge of the fabric to make it easier to remove them as you sew.

How many arms are there in a seat strap?
These straps were bent to contain 3 flat arms. Two arms extend from the lowest plane of the seat up to the frame and the ends were brazed there. The middle plane is horizontal and is the width of the center pleated panel plate. 1/8" thick white board was stapled to the cradle between these steel straps to further define that panel shape.
How thick is a headrest?
The headrest was made from glued up layers of plywood. Total thickness of the piece is about 3 1/2" and is made in two halves. Once the glue was dry, the two halves where screwed together with 4 countersunk drywall screws and the shape rounded with a 4 1/2" angle grinder mounted with a 36 grit sanding disk. This makes clouds of sanding dust sob I used a dust mask but forming the shape is very easy. Note that the plies in the wood allow the shape to be contoured perfectly symmetrical just following the glue lines.
