	Diseases of the Nasal Cavities and Paranasal Sinuses
		The frontal and maxillary sinuses are air filled spaces formed by the evagination of the frontal and maxillary bones into the embryonic nasal cavity and these sinuses communicate directly with the nasal cavity [ 6 ].
		The maxillary sinuses in the horse are unique in being divided into separate rostral and caudal parts by a thin, cribiform bony septum, which is variable in position [ 4 ] and is often incomplete in the donkey.
		Proliferation of the maxillary bones due to nutritional secondary hyperparathyroidism causing nasal airway obstruction may be due to excessive dietary phosphorus [ 57-59 ], due to a diet consisting of excessive amounts of bran or grazing on certain tropical grasses.

		Maxillary hypoplasia results from the underdevelopment of the maxillary bones and produces midfacial retrusion, creating the illusion of protuberance of the lower jaw.
		The orbital floor serves as the roof of the maxillary sinus and transmits the infraorbital neurovascular structures via the infraorbital groove and canal.
		The maxillary bone is composed of 4 vertical buttresses.

	Maxillary Growth
		The midface, or maxillary complex, is comprised of the paired maxillae, nasal bones, zygomatic bones, palatine bones and vomer.
		As the maxillary complex rotated 1,5 degrees forward in relation to the anterior cranial base (true rotation) and the palatal plane rotated 2,5 degrees backward (remodeling rotation), the result is 1 mm degree increase in the inclination of the palatal plane to the anterior cranial base ( backward, represented by apparent rotation).
		The peak of the eruption of the maxillary molars is at the age of 12 years and shows a postpuberal decrease in velocity until the age of 17.

	An Anterior Tooth Size Comparison in Unilateral and Bilateral Aplastic Maxillary Lateral Incisors
		The absence of maxillary lateral incisors may be an expression of an evolutionary trend of relaxed selection leading to the simplification of man’s dentition through a reduction in tooth number (2).
		In the absence of maxillary lateral incisors, the maxillary central incisors were used as a reference to determine the ideal mesiodistal width.
		Referring to Wheeler’s work, the average width of a maxillary lateral incisor is 6.5mm.(8) In this study the average width was 5.9mm with a standard deviation of 1.3mm and a range of 4.1 to 8.0mm.

	Surgically Assisted Rapid Palatal Expansion (Site not responding. Last check: 2007-11-04)
		The effective maxillary width defines the width of the maxillia and is the linear measurement between the points JL and JR (bilateral points on the jugal process at the intersection of the outline of the maxillary tuberosity and the zygomatic buttress).
		Posteriorly, the bony incision is angled inferiorly to terminate at the inferior junction of the maxillary tuberosity and pterygoid plate.
		The width of the maxillary arch can also be maintained by stablizing the appliance either by passing a piece of wire through the hole in the expansion screw and looping it around the anterior guide rod, or by adding cold curing acrylic resin to the central portion of the expansion appliance.

	WSAVA 2001 - Recognizing Oral Disease
		In the normal occlusion, the maxillary and mandibular incisors overlap slightly so that the occlusal edge of the mandibular incisors rests on the cingulum of the maxillary incisors.
		Base narrowed canines may be due to a structural narrowing of the mandible, or failure of the primary teeth to exfoliate prior to the eruption of the adult canine teeth.
		Similar to the mandibular incisor teeth, fractures of the mandibular molars and premolars may be difficult to detect because of the overlap of the tongue and because they frequently occur on the lingual side of the tooth.

		This is true irrespective of the number of maxillary segments involved during the osteotomy or age of the patient.
		In general, in fully grown patients, an overcorrection of the overjet in maxillary distraction with the use of the RED is not required.
		In other patients whose arches are not well coordinated, and in patients who are very young, maxillary distraction with the RED is a very important intermediate procedure which allows the surgeon to obtain substantial maxillary advancement with good alignment of the basal skeleton between the upper and lower jaws.

		The maxillary sinuses are a subset of theÂ paranasal sinuses Â and can generally be thought of as the sinuses, or cavities, beneath the cheeks and on the sides of the nose.
		The maxillary sinuses are the most common region that paranasal sinus cancer arises, and most cancers in the maxillary sinuses are squamous cell carcinomas, meaning they arise from flat, thin cells in the epidermis lining the maxillary sinus.
		Depending on the type and stage of the tumors, maxillary sinus cancers are usually treated with surgery and radiation, and in advanced cases chemotherapy.

		The maxillary bones form the upper jaw; together they are the keystone of the face, for all other immovable facial bones are connected to them.
		These air-filled spaces are the largest of the sinuses, and they extend from the floor of the orbits to the roots of the upper teeth.
		During development, portions of the maxillary bones called "palatine processes" grow together and fuse along the middle to form the front section of the hard palate.

		To understand the process, let us consider the anatomic details of the maxillary cavity, as it will help you comprehend how and why antritis occurs and what principles are used in the treatment of this disease.
		As the opening connecting the sinus with the nasal cavity is in the upper part of the maxillary sinus, a properly-working excretion mechanism is crucial for the discharge to leave the cavity freely.
		As is already mentioned, antritis is caused by the swelling of the mucous membrane in the nose, blocking the opening between the maxillary sinus and the nasal cavity.

		The maxillary sinus is housed in the body of the maxilla, with the inferior orbital wall as the superior border, the lateral nasal wall as the medial boundary, the alveolar process of the maxilla as its inferior border, and the canine fossa as the anterior border.
		The main functional component of the maxillary sinus outflow tract is the ostiomeatal complex, which is collectively constituted by the uncinate process, the maxillary ostium, the infundibulum, and the ethmoid bulla.
		The maxillary sinus should be inspected with a 30- or 70-degree scope to ensure that no further disease is present within the sinus and that the natural ostium was included in the antrostomy.

		The size was chosen based on measuring the intermolar width on the pretreatment study casts from the maxillary molar lingual groove at the gingiva to the opposite lingual groove and adding 3-4mm to the measurement.
		Expansion is usually considered adequate once the occlusal aspect of the maxillary lingual cusp of either the permanent first molar or primary second molar contacts the occlusal aspect of the mandibular facial cusp of either the permanent first molar or primary second molar.
		Maxillary expansion is needed around mixed dentition period to approximate the anterior and posterior alveolar segments in preparation for the alveolar bone graft.

	Sinus Headaches and Dental Health
		The sinus that most commonly becomes infected is the maxillary sinus due to it prominent exposure to the environment and the anatomy that allows drainage of the cavity.
		In the maxillary sinus the mucus must move upward to drain from the sinus and to the nasal cavity.

		The complexity of the root canal system of maxillary molars presents a constant challenge, as the dentist must have a thorough knowledge of root canal morphology to provide successful endodontic treatment.
		The form, configuration, and number of root canals present in maxillary first molars have been discussed for more than half a century.1-12 Differences between studies may be attributed to variations in the technique used to study the morphology.
		This case report describes a permanent maxillary first molar with 5 root canals (2 MB, 1 DB, and 2 palatal), with unusual palatal canal morphology in that 2 canals with separate orifices join in the apical third.
