What is the purpose of posterior teeth?
They make it easier to process and digest plant foods. These back teeth are primarily used for grinding. There are some distinctions between maxillary and mandibular posterior teeth.
What occurs in posterior teeth after tooth loss?
Abstract. Purpose: Tooth positional changes following posterior tooth loss may alter arch forms and occlusal planes. This may result in the development of occlusal interferences.
What is the chewing surface of posterior teeth called?
Occlusal: It’s the chewing surface of posterior teeth. Proximal: It’s the region in tooth surfaces that are next to each other i.e., distal of the lateral incisor and mesial of canine.
What is dental and occlusion effect?
Occlusion, in a dental context, means simply the contact between teeth. More technically, it is the relationship between the maxillary (upper) and mandibular (lower) teeth when they approach each other, as occurs during chewing or at rest.
What is posterior dentistry?
In dentistry, the term posterior teeth usually refers as a group to the premolars and molars, as distinguished from the anterior teeth, which are the incisors and canine teeth. The distinction is one of anterior (front of the body) versus posterior (rear of the body).
What is the difference between posterior and anterior teeth?
Permanent teeth are divided into two groups: anterior teeth and posterior teeth. Anterior teeth include the teeth toward the front of the mouth, including the central incisors, the lateral incisors, and the canines, while posterior teeth, or the teeth toward the back of the mouth, include the premolars and molars [1].
What is supra eruption?
Definition. Occurs where a missing tooth or delayed replacement of lost teeth leads to extrusion of the opposing teeth into the edentulous space. [
How can supra eruption be prevented?
Prevention of Supraeruption: Supraeruption of tooth/teeth can be prevented by the light forces generated during chewing against an antagonist (Gierie et al., 1999).
How many surfaces do posterior teeth have?
Anterior teeth therefore have surfaces numbered 1 to 4, and posterior teeth have surfaces numbered 1 to 5 (Fig. 1). The surface number is then used as suffix to the tooth number.
What is posterior guidance?
Posterior guidance is the result of: (1) contact of mandibular posterior teeth against maxillary posterior teeth in intercuspal contact position and (2) movement of mandibular posterior teeth along cuspal inclines of maxillary posterior teeth during mandibular contact movements.
What occurs when a tooth extends above the line of occlusion?
Overeruption, in dentistry, is the physiological movement of a tooth which is missing an opposing partner in the dental occlusion. Due to the lack of opposing force, in addition to the natural eruptive potential of the tooth, there is a tendency for the tooth to erupt outside the line of the occlusion.
What are dental posterior composites?
Posterior composite fillings( white fillings on back teeth) The same type of filling material used to do bondings and fillings on front teeth can be used to fill back teeth. Traditionally, Amalgam fillings were considered the only choice for fillings on back teeth.
What are the causes of supra eruption of teeth?
The results show that in the first years following the loss of the opposing tooth, supraeruption is mainly due to growth of the periodontium. Later or in the case of periodontal pathosis, tooth movement beyond the occlusal plane is due principally to active eruption.
Can braces fix overeruption?
Overeruption is typically treated by directing the tooth back to the intended position using orthodontic techniques, or by cutting the interfering portion of the tooth and installing a crown.
What is the study of teeth?
Terminology. The term dentistry comes from dentist, which comes from French dentiste, which comes from the French and Latin words for tooth. The term for the associated scientific study of teeth is odontology (from Ancient Greek: ὀδούς, romanized: odoús, lit.
What is anterior and posterior teeth?
