Class I: The molar relationship of the occlusion is normal or as described for the maxillary first molar, with malocclusion confined to anterior teeth [4] Class II : The retrusion of the lower jaw with distal occlusion of the lower teeth (or in other words, the maxillary first molar occludes anterior to the buccal groove of the mandibular first ...
Arguments for canine guided occlusion in complete dentures have been gaining momentum because of its ease of fabrication and better patient preference. [19] There has been a presumption that canine guided occlusion in complete dentures promotes denture instability by introducing interferences during function.
Static occlusion refers to contact between teeth when the jaw is closed and stationary, while dynamic occlusion refers to occlusal contacts made when the jaw is moving. [ 1 ] The masticatory system also involves the periodontium , the TMJ (and other skeletal components) and the neuromusculature, therefore the tooth contacts should not be looked ...
Orthodontists generally use 12-16 oz elastics (3/16") in extraction cases or 2× 6 oz elastics on either side of the mouth (3/16"), but in non extraction cases 16-20 oz elastics (3/16") or 2× 8 oz elastics are used. It is very important to know the side effects of Class II elastics before using them in an orthodontic treatment.
5.3.1 Class II Division 1. 5.3.2 ... The teeth should all fit on a line of occlusion which, in the upper arch, is a smooth curve through the central fossae of the ...
Retention demands are significantly less following serial extraction. However it is better to follow a regular retention regimen for the first six months against possible relapse of rotations and to allow settling of the occlusion. A maxillary Hawley type retainer and a bonded mandibular canine to canine retainer make an efficient retention ...
The concept of ideal occlusion, as postulated by Angle and incorporated into a classification system, enabled a shift towards treating malocclusion, which is any deviation from normal occlusion. [8] Having a full set of teeth on both arches was highly sought after in orthodontic treatment due to the need for exact relationships between them.
Occlusal trauma; Secondary occlusal trauma on X-ray film displays two lone-standing mandibular teeth, the lower left first premolar and canine. As the remnants of a once full complement of 16 lower teeth, these two teeth have been alone in opposing the forces associated with mastication for some time, as can be evidenced by the widened PDL surrounding the premolar.
