The dental arches are the two arches (crescent arrangements) of teeth, one on each jaw, that together constitute the dentition.In humans and many other species, the superior (maxillary or upper) dental arch is a little larger than the inferior (mandibular or lower) arch, so that in the normal condition the teeth in the maxilla (upper jaw) slightly overlap those of the mandible (lower jaw) both ...
Full arch restoration in dentistry refers to the comprehensive reconstruction or rehabilitation of an entire dental arch, which can include all teeth in the upper or lower jaw. [ 1 ] [ 2 ] This procedure is also known as full mouth reconstruction or full mouth rehabilitation.
The curved portion of the process is referred to as the alveolar arch. [5] The alveolar bone proper , also called bundle bone , directly surrounds the teeth. [ 6 ] The terms alveolar border , alveolar crest , and alveolar margin describe the extreme rim of the bone nearest to the crowns of the teeth.
Dental quadrants The dentition is divided into four quarters. The two dental arches form an oval, which is divided into quadrants which are numbered from 1 to 4: [7] Upper right quadrant: upper right first incisor to upper right wisdom tooth; Upper left quadrant: upper left first incisor to upper left wisdom tooth
Most often, the cause of impaction is inadequate arch length and space in which to erupt. That is the total length of the alveolar arch is smaller than the tooth arch (the combined mesiodistal width of each tooth). The wisdom teeth (third molars) are frequently impacted because they are the last teeth to erupt in the oral cavity.
The first arch, as the first to form, separates the mouth pit or stomodeum from the pericardium. By differential growth the neck elongates and new arches form, so the pharynx has six arches ultimately. Each pharyngeal arch has a cartilaginous stick, a muscle component that differentiates from the cartilaginous tissue, an artery, and a cranial ...

Primary failure of eruption (PFE) is a rare disease in which tooth eruption does not occur despite space in the arch for eruption. Non-eruption of non-ankylosed teeth occurs due to an eruption mechanism that has failed leading to a posterior unilateral/bilateral open bite. [28] Infra occlusion is the primary hallmark of PFE.
