This document provides instructions for bulbous loop bending, including marking a 5.5mm point and forming a 7.5mm loop to serve as a distal driving posterior tooth, with the loop bent symmetrically at 60 degrees, 90 degrees, and 60 degrees.

This document describes a shoe horn loop with dimensions of 2.5mm and 6.5mm that bends at an angle between 5 and 20 degrees. The document also illustrates the direction of force needed to insert a shoe into a shoe horn using the loop, with arrows showing that the force must be applied in the direction that the loop is bending.
The document describes the specifications and use of Opus closing loops as orthodontic anchorage. Key details include:
- Used as moderate anchorage with forces of 150-200 grams each side.
- Maximum activation of 0.016 x 0.022, 0.018 x 0.025, and 0.017 x 0.025 sizes.
- Designed for off-center positioning 2.5mm from canine brackets.
This document discusses orthodontic treatment using closing loops made of different materials. Stainless steel closing loops produce higher horizontal forces and load/deflection ratios compared to beta titanium loops. A moment/force ratio of 9.3 is optimal for retracting anterior teeth in a 0.022-inch slot system. Placement of the closing loop can affect whether it encourages root tipping through moment forces or translation. Alternatives like bending the archwire or using mini screws or headgear may be needed to prevent unwanted side effects like a deep bite.
The document contains measurements of different parts of a person's face:
- The upper face is 35% long, the middle face is 37% long, and the lower face is 18% long, which is shorter than normal.
- The mouth is wider than normal, with the right side 58% and the left side 42%.
- The ratio between lateral canthi and cheilion measurements indicates a wider mouth.
- The face is unbalanced with some parts longer or wider than normal.
This document describes a diagnostic and prognostic tool to identify disturbances in the eruption of the upper canine tooth at an early developmental stage using 3 sentences or less:
The tool uses measurements of the distances between craniofacial landmarks taken from radiographs to calculate a score, where a score less than -0.565 indicates a 95.3% chance the canine will be impacted during eruption. Two examples are provided to illustrate use of the tool.
