Abstract: An orthodontic appliance has a post attached to a first upper tooth, and a button with a recess attached to a second upper tooth. An elongated arm has an eye at one end through which the post is inserted to allow the elongated arm to rotate about the post, and a tip at the other end for removable insertion into the recess of the button. The length of the elongated arm is selectable to maintain a desired spacing between the first and second upper teeth (e.g., by cutting the tip of the elongated arm). An elastic extends from either the post or button to an attachment point on the patient's lower dental arch to exert a force between the patient's maxilla and mandible.

Abstract: A method for planning a root canal treatment of a tooth which includes a cavity of a patient. The method includes measuring a surface of the cavity with an optical three-dimensional method to generate three-dimensional measurement data of the cavity. A 3D-model of a guide template is planned based on the generated three-dimensional measurement data. The 3-D model is designed in its dimensions as a counterpart to the cavity. Three-dimensional volume data of the tooth is displayed. A position and an orientation of a root canal of the tooth is determined based on the three-dimensional volume data of the tooth. A guide opening for a tool is planned to expose the root canal. The guide opening is arranged within the guide template so that the guide opening points at an entry point of the root canal and in an entry direction of the root canal.
