Dental appliance having a duplicated tooth area and/or a predicted tooth area and a method for correcting the position of the teeth of a patient

A dental appliance worn in a mouth of a user, the dental appliance comprising:

• a generally U-shaped base having a length defined between a first end and a second end and further having a top surface and a bottom surface wherein the base is sized to receive one or more teeth of a user and further wherein a first portion of the base is shaped based on a predicted size of one or more teeth of the user which have not erupted and a second portion of the base is shaped based on a size of one or more teeth of the user which have erupted.

A dental appliance worn in the mouth of the user, the dental appliance comprising:

• a generally U-shaped base generated by a computer and sized to receive one or more teeth of a user wherein the size of the base is predicted based on one or more teeth of the user which have not erupted.

A dental appliance worn adjacent to teeth in a mouth of a user, the dental appliance comprising:

• a generally U-shaped base sized to receive one or more teeth of a user wherein the base contains sockets for receiving one or more teeth and wherein a size of each of the sockets is computer-generated based on a predicted size of one or more incisors of the user which have not erupted.

A dental appliance comprising:

• a generally U-shaped base sized to receive one or more teeth of a user wherein the base has a perimeter;
• and
• a wall extending along the perimeter of the base wherein the base and the wall are shaped to receive a tooth which has not erupted and wherein the base and the wall are sized based on a size of one or more erupted permanent teeth.

A dental appliance work adjacent to teeth in a mouth of a user, the dental appliance comprising:

• a generally U-shaped base sized to receive one or more of the teeth of the user;
• and
• sockets within the base wherein the sockets are sized to receive teeth of the user which have not erupted wherein the size of one of the sockets is based on an image of an interior of a mouth of the user.

A dental appliance comprising:

• a generally U-shaped base sized to receive teeth in a mouth of a user;
• and
• a socket within the base wherein the socket has walls defining an interior and is shaped to receive one or more teeth of the user and wherein the socket has a rib formed within the walls of the socket wherein the rib causes rotation of the teeth.

A dental appliance worn by a user having anterior teeth and posterior teeth in a mouth of the user, the dental appliance comprising:

• a generally U-shaped base wherein the base is sized based on a predicted size of one or more teeth which have not erupted and wherein the base contacts the anterior teeth of the user and wherein the base does not contact one of the posterior teeth of the user.

A dental appliance worn adjacent to teeth in a mouth of a user, the dental appliance comprising:

• a generally U-shaped base having an inside perimeter and an outside perimeter;
• a wall extending from the base along the outside perimeter wherein the wall has a surface and wherein the wall has one or more protrusions extending from the surface wherein the protrusions contact a lip of the user.

A sheet for treating a malocclusion of a user having teeth, the sheet comprising:

• a first portion wherein the first portion is constructed from a first material;
• and
• a second portion wherein the second portion is constructed from a second material wherein the first material is softer than the second material and further wherein the sheet is molded into a dental appliance for treating the malocclusion wherein the first material contacts teeth requiring correction and wherein the second material contacts teeth which do not require correction.

A system for treating a malocclusion, the system comprising:

• a first dental appliance worn in the mouth of a user having the malocclusion wherein a portion of the first dental appliance is shaped based on a predicted size of one or more teeth of the user which have not erupted;
• and
• a second dental appliance worn in the mouth of the user after the user wears the first dental appliance wherein a portion of the second dental appliance is shaped in correlation to teeth partially corrected by the first dental appliance.

A U-shaped dental appliance for correcting a malocclusion comprising a duplicated tooth area which suppresses movement of a certain tooth or certain teeth and a predicted tooth area, which allows or guides tooth movement of another tooth or other teeth, wherein the duplicated tooth area comprises a tooth socket or sockets made of stiff material and the predicted tooth area comprises a tooth socket or sockets made of soft material.

A kit comprising at least two U-shaped dental appliances for correcting a malocclusion, each or every dental appliance comprising a duplicated tooth area which suppresses movement of a certain tooth or certain teeth and a predicted tooth area, which allows or guides tooth movement of another tooth or other teeth, wherein the duplicated tooth area comprises a tooth socket or sockets made of stiff material and the predicted tooth area comprises a tooth socket or sockets made of soft material.

A dental appliance worn adjacent to teeth of the user, the dental appliance comprising:

• a generally U-shaped base wherein the base is sized to receive one or more teeth of the user and further wherein a first portion of the base is shaped based on a predicted size of one of the teeth of the user which has not erupted wherein the prediction is based on an anatomical standard for a size of a tooth.
