Ovoid and Modified Ovoid Arrangements
Labial Aspect Incisal Aspect Discription
19.
Basic
Arrangement
Mould 65G illustrated
The typical full curvature of the arch is shown in this Ovoid-type arrangement. The soft Ovoid characteristics of the tooth form are quite evident in the centrals, laterals and canines, and the teeth are set to a full curve.
20.
Softened
Arrangement
Mould 55F illustrated
A softening effect of the basic Ovoid arrangement developed by using tooth forms slightly less broad in their labial aspect. A Tapering Ovoid tooth form is set to the characteristic curve of the Ovoid arch. The long axis of the centrals is noticeably divergent. The laterals are elevated and canines have been rotated in slightly at the distal.
21.
Vigorous
Arrangement
Mould 62G illustrated
A vigorous arrangement of the basic Ovoid form. Mould 62G is a wider and longer ovoid form and presents a bolder labial surface. This is noticeably accentuated by the outward rotation of the centrals at the distal.
22.
Asymmetrical
Arrangement
Mould 32E illustrated
This arrangement utilizes a Square Ovoid form as part of the asymmetrical influence. This effect has been created by the depression of the right lateral and canine. The left lateral is elevated, rotated and spaced at the mesial.
23.
Crowded
Arrangement
Mould 62D illustrated
While the crowded condition is not too commonly observed in the Ovoid arch, the eruption of oversized teeth in a normal or small arch will obviously produce crowding. This is generally manifest by a lapping and rotating within the basic curvature of the Ovoid-type form. Characteristically, this lapping or rotating is usually minor and not as pronounced as in the Tapering arch form.
24.
Spaced
Arrangement
Mould 55D illustrated
An example of an Ovoid modified form (Tapering Ovoid) in an Ovoid arch. The teeth are slightly out of proportion, being smaller than normal for this size arch. This manifests itself by variable spacing between one or more of the teeth.
