The use of steel ligatures is recommended on all brackets, even the tooth-colored
brackets, because elastometric rings attract significantly more plaque than steel ties.
Self-Ligating braces eliminate the need for elastic or metal ties

Orthodontic bands that extend subgingivally, coupled with plaque accumulation
where a generalized increase in salivary bacterial counts, especially Lactobacillus,
had been shown after orthodontic band placement.

periodontal support loss
Bone surrounding a tooth subjected to a force (Reitan 1985, Proffit 1993a)
Resorption occurs where there is pressure
New bone forms where there is tension

Many clinicians believe Traumatic occlusion
causes Intrabony Periodontal defects but this
is not so. This defect is caused by dental
plaque with accentuation due to the open
contact region and poor subgingival margin of
Restoration.
First molar has traumatic occlusion causing
the bone loss in the furca. Clinically there is
no pocket depth nor Periodontitis in the
furcation and so the diagnosis is Traumatic
Occlusion and the treatment is occlusal
adjustment to reduce occlusal loading.
