A process is for preparing polymeric particles for use as impact modifiers in curable (meth)acrylic resin compositions. Further, the process relates to a cured (meth)acrylic resin composition, in particular to adhesive or coating materials containing polymeric particles dispersed in a cured (meth)acrylic resin matrix. Said composition can be advantageously used as an adhesive, coating or a composite material.

An orthodontic appliance is disclosed. The orthodontic appliance includes an elongated receptacle, an elongated member telescopically extending from the receptacle and adapted to couple to one or more teeth, and an elastic coupled to the elongated member. The elastic member is configured to move the elongated member towards the elongated receptacle. A movement of the elongated member relative to the elongated receptacle facilitates a repositioning of one or more teeth.

An aligner assembly for facilitating an alignment of one or more teeth is disclosed. The aligner assembly includes a shell adapted to receive the one or more teeth. The aligner assembly further includes one or more engagement structures configured to be coupled to one of the one or more teeth or the shell. Each engagement structure includes a slot and adapted to engage with the shell for facilitating a reposition of the one or more teeth.

According to one or more embodiments, a computer implemented system for providing an orthodontic care management solution and a method for providing an orthodontic care management solution may be provided. The method may include receiving user data, such as by a user interface associated with an orthodontic care management platform. The method may further include obtaining authorization related information associated with the orthodontic care management solution. Additionally, the method may include determining a treatment plan for the user based on the user data and the authorization-related information. Also, the method may include determining a sequencing plan associated with the treatment plan based on an arrangement of one or more stages of operations associated with the treatment plan. The method may further include displaying the sequencing plan to the user. Further, the method may include receiving feedback data associated with the treatment plan. Additionally, the method may include updating the one or more databases with the feedback data. Further, the method may include performing an artificial intelligence enabled operation for providing the orthodontic care management solution.

The invention relates to a method for contructing at least one dental prosthetic part (20) or a bracket, with at least one adhesive surface (2), in which a 3D model (1) is made of the dental prosthetic part (20). Recesses (3,9,12,15,29,31) are constructed on the adhesive surface (2) of the 3D model (1).
