[The establishment and analysis of expending dental arch]
Abstract:
Expending dental-arch is one of the methods being used popularly in orthodontics.but there are few researches on its basical laws.In this paper,we used mathematic methods to discuss the relationship of the arch-length(S),the width(A),and the length of dental-arch(H).We devised a mathematic model,hoping it could be useful to orthodontic therapy.

Teeth
The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...

Spanning Openings in Brick Walls
In brick wall construction, supporting structures are crucial for openings like windows and doors to maintain the integrity and support the weight of the wall above. These supports include lintels, corbels, and arches, each serving specific structural purposes.
Lintels are primary supports used to span openings and can be crafted from materials such as reinforced concrete, steel-reinforced brick masonry, or simple steel angles. These are straightforward to install and are typically concealed...
