Dental Prosthesis
A dental prosthesis is an intraoral (inside the Human mouth, mouth) prosthesis used to dental restoration, restore (reconstruct) intraoral defects such as missing Human tooth, teeth, missing parts of teeth, and missing soft or hard structures of the jaw and palate. Prosthodontics is the dental specialty that focuses on dental prostheses. Such prostheses are used to rehabilitate mastication (chewing), improve aesthetics, and aid speech. A dental prosthesis may be held in place by connecting to teeth or dental implants, by suction, or by being held passively by surrounding muscles. Like other types of prostheses, they can either be fixed permanently or removable; fixed prosthodontics and removable dentures are made in many variations. Permanently fixed dental prostheses use dental adhesive or screws, to attach to teeth or dental implants. Removal prostheses may use friction against parallel hard surfaces and undercuts of adjacent teeth or dental implants, suction using the mucous re ...

Partial Denture
A removable partial denture (RPD) is a denture for a partially edentulous patient who desires to have replacement teeth for functional or aesthetic reasons and who cannot have a bridge (a fixed partial denture) for any reason, such as a lack of required teeth to serve as support for a bridge (i.e. distal abutments) or financial limitations. This type of prosthesis is referred to as a ''removable partial denture'' because patients can remove and reinsert it when required without professional help. Conversely, a "fixed" prosthesis can and should be removed only by a dental professional. The aim of an RPD is to restore masticatory function, speech, appearance and other anatomical features. Usage RPD may be used when there is a lack of required teeth to serve as support for a bridge (i.e. distal abutments) or financial limitations. A single-tooth RPD known as a "flipper tooth" may be used temporarily after a tooth is extracted, during the several months it takes to complete the ...

Dentistry
Dentistry, also known as dental medicine and oral medicine, is the branch of medicine focused on the Human tooth, teeth, gums, and Human mouth, mouth. It consists of the study, diagnosis, prevention, management, and treatment of diseases, disorders, and conditions of the mouth, most commonly focused on dentition (the development and arrangement of teeth) as well as the oral mucosa. Dentistry may also encompass other aspects of the craniofacial complex including the temporomandibular joint. The practitioner is called a dentist. The history of dentistry is almost as ancient as the history of humanity and civilization, with the earliest evidence dating from 7000 BC to 5500 BC. Dentistry is thought to have been the first specialization in medicine which has gone on to develop its own accredited degree with its own specializations. Dentistry is often also understood to subsume the now largely defunct medical specialty of stomatology (the study of the mouth and its disorders and dis ...

Dental Braces
Dental braces (also known as orthodontic braces, or simply braces) are devices used in orthodontics that align and straighten Human tooth, teeth and help position them with regard to a person's bite, while also aiming to improve dental health. They are often used to correct Malocclusion, underbites, as well as malocclusions, overbites, open bites, gaps, deep bites, cross bites, crooked teeth, and various other flaws of the teeth and jaw. Braces can be either cosmetic or structural. Dental braces are often used in conjunction with other orthodontic appliances to help widen the palate or jaws and to otherwise assist in shaping the teeth and jaws. Braces are an orthodontic device. They are to make the teeth straight, and to correct problems in a person's bite. There are many natural problems which occur to the way teeth fit together, but not everyone needs or will need braces. However, the use of braces is quite common, even when they are not medically necessary. Their cosmetic use f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dental Restoration
Dental restoration, dental fillings, or simply fillings are treatments used to restore the function, integrity, and morphology of missing tooth structure resulting from caries or external trauma as well as the replacement of such structure supported by dental implants. They are of two broad types—''direct'' and ''indirect''—and are further classified by location and size. Root canal therapy, for example, is a restorative technique used to fill the space where the dental pulp normally resides and are more hectic than a normal filling. History In Italy evidence dated to the Paleolithic, around 13,000 years ago, points to bitumen used to fill a tooth and in Neolithic Slovenia, 6500 years ago, beeswax was used to close a fracture in a tooth. Graeco-Roman literature, such as Pliny the Elder's Naturalis Historia (AD 23–79), contains references to filling materials for hollow teeth.

Pivot Tooth
The pivot tooth is a fixed dental Prosthodontics, prosthesis used to rebuild a Human tooth, tooth. It is a type of , but it is an independent supplement and usually consists of a pin or peg and a full Crown (dental restoration), crown permanently connected (i.e., without Dental cement, cement) and placed in the patient's oral cavity during a single visit. It often includes a protective element called a ferrule. Pivot teeth were developed to shorten the execution cycle and skip some laboratory steps. Although they could last for many years when used according to indications and contraindications, pivot teeth did not meet the requirements and are no longer used. Better results are achieved by permanently cementing the crown-root foundation and further crafting the crown as if it were a natural tooth stump prepared for the crown. Otherwise, the laboratory connection of the crown to the foundation carries a greater risk of inaccuracies, subsequent crown leakage, cement washout, and too ...

Bridge (dentistry)
A bridge is a fixed dental restoration (a fixed dental prosthesis) used to replace one or more missing teeth by joining an artificial tooth definitively to adjacent teeth or dental implants. Definitions Fixed bridge: A dental prosthesis that is definitively attached to natural teeth and replaces missing teeth. Abutment: The tooth that supports and retains a dental prosthesis. Pontic: The artificial tooth that replaces a missing natural tooth. Retainer: The component attached to the abutment for retention of the prosthesis. Retainers can be major or minor. Unit: Pontics and abutment teeth are referred to as units. The total number of units in a bridge is equal to the number of pontics plus the number of abutment teeth. Saddle: The area on the alveolar ridge which is edentulous where at least one missing tooth is to be reinstated. Connector: Joins the pontic to the retainer or two retainers together. Connectors may be fixed or movable. Span: The length of the alveo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crown (dentistry)
In dentistry, a crown or a dental cap is a type of dental restoration that completely caps or encircles a Human tooth, tooth or dental implant. A crown may be needed when a large dental cavity threatens the health of a tooth. Some dentists will also finish root canal treatment by covering the exposed tooth with a crown. A crown is typically bonded to the tooth by dental cement. They can be made from various materials, which are usually fabricated using ''indirect methods''. Crowns are used to improve the strength or appearance of teeth and to halt deterioration. While beneficial to dental health, the procedure and materials can be costly. The most common method of crowning a tooth involves taking a dental impression of a tooth prepared by a dentist, then fabricating the crown outside of the mouth. The crown can then be inserted at a subsequent dental appointment. This ''indirect method'' of tooth restoration allows use of strong dental restorative materials, restorative material ...

Orthodontic Technology
Orthodontic technology is a specialty of dental technology that is concerned with the design and fabrication of dental appliances for the treatment of malocclusions, which may be a result of tooth irregularity, disproportionate jaw relationships, or both. There are three main types of orthodontic appliances: active, passive and functional. All these types can be fixed or removable. Active appliances An active appliance is a device used to apply forces to the teeth to change the relationship of the teeth. Removable active appliances Removable active appliances are intended for simple tipping movements. Use of removable appliances in modern orthodontics is much more limited than in the past due to their various shortcomings. * Expansion and labial segment alignment appliance (ELSAA) Fixed active appliances Edward Angle, regarded as the father of American orthodontics, developed many universal fixed active appliances, unifying orthodontic practice. * Begg lightwire applianc ...

Palatal Obturator
{{no footnotes, date=February 2017 The Latham Device Post Latham Nasal Alveolar Molding Device Post Insertion A palatal obturator is a prosthesis that totally occludes an opening such as an oronasal fistula (in the roof of the mouth). They are similar to dental retainers, but without the front wire. Palatal obturators are typically short-term prosthetics used to close defects of the hard/soft palate that may affect speech production or cause nasal regurgitation during feeding. Following surgery, there may remain a residual orinasal opening on the palate, alveolar ridge, or vestibule of the larynx. A palatal obturator may be used to compensate for hypernasality and to aid in speech therapy targeting correction of compensatory articulation caused by the cleft palate. In simpler terms, a palatal obturator covers any fistulas (or "holes") in the roof of the mouth that lead to the nasal cavity, providing the wearer with a plastic/acrylic, removable roof of the mouth, which aids i ...

Dentures
Dentures (also known as false teeth) are prosthetic devices constructed to replace missing teeth, supported by the surrounding soft and hard tissues of the oral cavity. Conventional dentures are removable ( removable partial denture or complete denture). However, there are many denture designs, some of which rely on bonding or clasping onto teeth or dental implants ( fixed prosthodontics). There are two main categories of dentures, the distinction being whether they fit onto the mandibular arch or on the maxillary arch. Medical uses Dentures can help people via: * Mastication: chewing ability is improved by the replacement of edentulous (lacking teeth) areas with denture teeth. * Aesthetics: the presence of teeth gives a natural appearance to the face, and wearing a denture to replace missing teeth provides support for the lips and cheeks and corrects the collapsed appearance that results from the loss of teeth. * Pronunciation: replacing missing teeth, especially the ...

Human Mouth
In human anatomy, the mouth is the first portion of the alimentary canal that receives Human food, food and produces saliva. The oral mucosa is the mucous membrane epithelium lining the inside of the mouth. In addition to its primary role as the beginning of the digestive system, the mouth also plays a significant role in communication. While primary aspects of the voice are produced in the throat, the tongue, lips, and human mandible, jaw are also needed to produce the range of sounds included in speech. The mouth consists of two regions, the vestibule and the oral cavity proper. The mouth, normally moist, is lined with a mucous membrane, and contains the human teeth, teeth. The lips mark the transition from mucous membrane to human skin, skin, which covers most of the human body, body. Structure Oral cavity The mouth consists of two regions: the vestibule and the oral cavity proper. The vestibule is the area between the teeth, lips and cheeks. The oral cavity is bound ...
