An abnormal bite between the opposing teeth
can also affect periodontal health, and this could lead to the gingival recession with thinning of the alveolar bone and mobility of the opposing mandibular tooth/teeth [6, 9, 10].
Our teeth have a constant tendency to move both towards the front of our mouths and towards the opposing jaw, unless they are stopped by something in their way, usually the adjacent or opposing teeth
. Loss of teeth allows this to proceed.
In the absence of treatment or with extraction of the affected tooth, adjacent teeth could drift and opposing teeth
But in the 1940s, more than 15 percent of World War II recruits were denied the ability to enlist in the Army because they lacked six pairs of opposing teeth
This means that these opposing teeth
may need corrective trimming after the extraction of one opposing tooth.
These include the use of only one tray, which captures an impression of the prepared tooth, the adjacent and opposing teeth
, and the relationship between them in maximal intercuspation without the need for an interocclusal record.7
In most cases, the transplanted teeth are set in infraocclusion, free of any interference from the opposing teeth
. It is the author's experience that autotransplantation of ectopic permanent incisor teeth requires less challenging surgical preparation provided that adequate preoperative assessment was performed.
The patient had been thoroughly examined for all the possible contributing factors and was found with no skeletal abnormality, or history of habit except the malpositioned maxillary left premolar which was in buccal crossbite in relation to the opposing teeth
and palatally erupted maxillary left lateral incisor.
It's designed with high gloss properties, high wear resistance and low wear to opposing teeth
to help reduce abrasion and long-term retention.
