Maxillary diseases refer to various medical conditions primarily affecting the maxilla (upper jaw) bone, including inflammatory processes, tumors, cysts, or traumatic injuries, which may cause symptoms such as pain, swelling, or functional impairment.
The air space located in the body of the MAXILLARY BONE near each cheek. Each maxillary sinus communicates with the middle passage (meatus) of the NASAL CAVITY on the same side.
One of a pair of irregularly shaped bones that form the upper jaw. A maxillary bone provides tooth sockets for the superior teeth, forms part of the ORBIT, and contains the MAXILLARY SINUS.
Inflammation of the NASAL MUCOSA in the MAXILLARY SINUS. In many cases, it is caused by an infection of the bacteria HAEMOPHILUS INFLUENZAE; STREPTOCOCCUS PNEUMONIAE; or STAPHYLOCOCCUS AUREUS.
Tumors or cancer of the MAXILLARY SINUS. They represent the majority of paranasal neoplasms.
The intermediate sensory division of the trigeminal (5th cranial) nerve. The maxillary nerve carries general afferents from the intermediate region of the face including the lower eyelid, nose and upper lip, the maxillary teeth, and parts of the dura.

The upper part of the tooth, which joins the lower part of the tooth (TOOTH ROOT) at the cervix (TOOTH CERVIX) at a line called the cementoenamel junction. The entire surface of the crown is covered with enamel which is thicker at the extremity and becomes progressively thinner toward the cervix. (From Jablonski, Dictionary of Dentistry, 1992, p216)

Measurement of tooth characteristics.
Presentation devices used for patient education and technique training in dentistry.
The part of a tooth from the neck to the apex, embedded in the alveolar process and covered with cementum. A root may be single or divided into several branches, usually identified by their relative position, e.g., lingual root or buccal root. Single-rooted teeth include mandibular first and second premolars and the maxillary second premolar teeth. The maxillary first premolar has two roots in most cases. Maxillary molars have three roots. (Jablonski, Dictionary of Dentistry, 1992, p690)
The structure that forms the roof of the mouth. It consists of the anterior hard palate (PALATE, HARD) and the posterior soft palate (PALATE, SOFT).
The thickest and spongiest part of the maxilla and mandible hollowed out into deep cavities for the teeth.
A normal developing tooth which has not yet perforated the oral mucosa or one that fails to erupt in the normal sequence or time interval expected for the type of tooth in a given gender, age, or population group.
Such malposition and contact of the maxillary and mandibular teeth as to interfere with the highest efficiency during the excursive movements of the jaw that are essential for mastication. (Jablonski, Illustrated Dictionary of Dentistry, 1982)
Devices used for influencing tooth position. Orthodontic appliances may be classified as fixed or removable, active or retaining, and intraoral or extraoral. (Boucher's Clinical Dental Terminology, 4th ed, p19)
Surgery of the upper jaw bone usually performed to correct upper and lower jaw misalignment.
The planning, calculation, and creation of an apparatus for the purpose of correcting the placement or straightening of teeth.
Extraoral devices for applying force to the dentition in order to avoid some of the problems in anchorage control met with in intermaxillary traction and to apply force in directions not otherwise possible.
Fractures of the upper jaw.
The facial skeleton, consisting of bones situated between the cranial base and the mandibular region. While some consider the facial bones to comprise the hyoid (HYOID BONE), palatine (HARD PALATE), and zygomatic (ZYGOMA) bones, MANDIBLE, and MAXILLA, others include also the lacrimal and nasal bones, inferior nasal concha, and vomer but exclude the hyoid bone. (Jablonski, Dictionary of Dentistry, 1992, p113)
The process of growth and differentiation of the jaws and face.
The anteriorly located rigid section of the PALATE.
The surgical removal of a tooth. (Dorland, 28th ed)
A complete denture replacing all the natural maxillary teeth and associated maxillary structures. It is completely supported by the oral tissue and underlying maxillary bone.
Malocclusion in which the mandible is posterior to the maxilla as reflected by the relationship of the first permanent molar (distoclusion).
The tip or terminal end of the root of a tooth. (Jablonski, Dictionary of Dentistry, 1992, p62)
Extraoral body-section radiography depicting an entire maxilla, or both maxilla and mandible, on a single film.
The space in a tooth bounded by the dentin and containing the dental pulp. The portion of the cavity within the crown of the tooth is the pulp chamber; the portion within the root is the pulp canal or root canal.
The emergence of a tooth from within its follicle in the ALVEOLAR PROCESS of the MAXILLA or MANDIBLE into the ORAL CAVITY. (Boucher's Clinical Dental Terminology, 4th ed)
The length of the face determined by the distance of separation of jaws. Occlusal vertical dimension (OVD or VDO) or contact vertical dimension is the lower face height with the teeth in centric occlusion. Rest vertical dimension (VDR) is the lower face height measured from a chin point to a point just below the nose, with the mandible in rest position. (From Jablonski, Dictionary of Dentistry, 1992, p250)
The phase of orthodontics concerned with the correction of malocclusion with proper appliances and prevention of its sequelae (Jablonski's Illus. Dictionary of Dentistry).
The complement of teeth in the jaws after the eruption of some of the permanent teeth but before all the deciduous teeth are absent. (Boucher's Clinical Dental Terminology, 4th ed)
Orthodontic appliances, fixed or removable, used to maintain teeth in corrected positions during the period of functional adaptation following corrective treatment. These appliances are also used to maintain the positions of the teeth and jaws gained by orthodontic procedures. (From Zwemer, Boucher's Clinical Dental Terminology, 4th ed, p263)
The total absence of teeth from either the mandible or the maxilla, but not both. Total absence of teeth from both is MOUTH, EDENTULOUS. Partial absence of teeth in either is JAW, EDENTULOUS, PARTIALLY.
Attachment of orthodontic devices and materials to the MOUTH area for support and to provide a counterforce to orthodontic forces.
Transverse sectioning and repositioning of the maxilla. There are three types: Le Fort I osteotomy for maxillary advancement or the treatment of maxillary fractures; Le Fort II osteotomy for the treatment of maxillary fractures; Le Fort III osteotomy for the treatment of maxillary fractures with fracture of one or more facial bones. Le Fort III is often used also to correct craniofacial dysostosis and related facial abnormalities. (From Dorland, 28th ed, p1203 & p662)

Resorption in which cementum or dentin is lost from the root of a tooth owing to cementoclastic or osteoclastic activity in conditions such as trauma of occlusion or neoplasms. (Dorland, 27th ed)
