Theories abound: Genuine misery due to starvation, art directors who don't want to draw attention away from the goods, attempts to seem superior (primates show teeth as a sign of submissiveness).
Those adjustments were necessary due to differences in the long axis angulation of the superior and inferior teeth.
However, there is some evidence that teeth are superior to bone as an indicator of cumulative Pb exposure because the losses from teeth are much slower (Maneakrichten et al. 1991).
With visualization of the hypothetical coronal changes, it appears clear that measuring the whole tooth appears superior when compared to the roots only given the additional variability associated with measuring the roots only is more than can be expected from coronal changes over the short term (1 to 2 years).
They offer superior esthetics, require minimal tooth preparation, and are widely used for anterior and posterior restorations.
When surgery is performed by installing a guide with teeth support, the superior suitability of stents can result in very accurate outcomes.
The teeth on the superior and inferior surfaces were designed to engage into the endplate to provide additional stability.
Postoperative external immobilization is certainly necessary in the absence of a plate; however, the risk of device extrusion was probably less with this kind of cervical cage as a s result of titanium pins and retention teeth over the superior and inferior surfaces.
This approach appears to be more clinically relevant since the amount of superior movement of the maxillary posterior teeth by either orthognathic surgery or orthodontic tooth movement is dictated by the treatment plan tailored to each individual case.
A previous study has shown that natural soft tissue healing at 6 weeks after tooth extraction was superior when socket sealing surgery was performed in the extraction socket along with the bone graft [8].
By contrast, interfaces found in natural material systems, eg, bone, teeth, and shells, exhibit superior performance and appear to overcome the difficulties that plague engineered interfaces/joints.
