active eruption teeth definition
The purpose of this study is to determine the eruption patterns of maxillary and. mandibular central incisors from the first occlusal contacts to adulthood. Previous. studies have failed to obtain measurements into adulthood. Pre-functional active eruption is defined by. the movement of the tooth from the developmental position inside the jaw, through the. oral epithelium, into the oral cavity, to a final position of functional occlusion. Tooth eruption is a process in tooth development in which the teeth enter the mouth and become visible. It is currently believed that the periodontal ligament plays an important role in tooth eruption. The first human teeth to appear, the deciduous (primary) teeth (also known as baby or milk teeth), erupt into the mouth from around 6 months until 2 years of age, in a process known as  teething . At that time, the first permanent tooth erupts and begins a time in which there is a combination of primary and permanent teeth, known as the mixed dentition stage, which lasts until the last primary tooth is lost. 1. an issuing forth suddenly and violently; outburst; outbreak. 2. the ejection of molten rock, steam, etc., as from a volcano or geyser. 3. something that is erupted or ejected, as molten rock. 4. a. the breaking out of a rash or the like. 1. explosion, discharge, outburst, venting, ejection the volcanic eruption of Tambora in 1815. 2. flare-up, outbreak, sally the sudden eruption of violence on the streets of the city. 3. (Medical) inflammation, outbreak, rash, flare-up an unpleasant eruption of boils. noun. Case 1: Overgrown Gums (Altered Passive Eruption) The gums normally recede as a part of the normal eruption of the teeth. This is called passive eruption since the teeth aren't really moving or erupting, but the receeding of the gums creates the impression of active tooth movement. The teeth are usually not too short, they are usually normally-sized. Pre-Treatment. The overgrown gums interefere with seeing the normal tooth length and form. She has irregularities on the enamel surfaces and restorative facings are to be placed for a cosmetic enhancement. The gum surgery is required to expose enough tooth to allow for the proper form and esthetics on the restorations. Permanent teeth in the maxillae erupt in a different order from permanent teeth on the mandible. Maxillary teeth erupt in the following order: (1) first molar (2) central incisor, (3) lateral incisor, (4) first premolar, (5) second premolar, (6) canine, (7) second molar, and (8) third molar. Noun. 1. eruption-the sudden occurrence of a violent discharge of steam and volcanic material. volcanic eruption. discharge-the sudden giving off of energy. Plinian eruption-a volcanic eruption in which a stream of gas and ash is violently ejected to a height of several miles.
