Periodontal Surgery
Periodontal surgery is a form of dental surgery that prevents or corrects anatomical, traumatic, developmental, or plaque-induced defects in the bone, gingiva, or alveolar mucosa. The objectives of this surgery include accessibility of instruments to root surface, elimination of inflammation, creation of an oral environment for plaque control, periodontal diseases control, oral hygiene maintenance, maintain proper embrasure space, address gingiva-alveolar mucosa problems, and esthetic improvement. The surgical procedures include crown lengthening, frenectomy, and mucogingival flap surgery. Indications Contraindications Some contraindications include: * Patient with poor standard of plaque control * Questionable long-term prognosis of patient dentition * Pregnancy * Smoking * Severe cardiovascular disease * Malignancy * Bleeding disorders * Uncontrolled diabetes * Kidney disease * Liver disease Considerations * The procedural selection in a periodontal surgery should rely on ...

Dental Surgery
Dental surgery is any of a number of medical procedures that involve artificially modifying dentition; in other words, surgery of the teeth, gums and jaw bones. Types Some of the more common are: * Endodontic (surgery involving the pulp or root of the tooth) ** Root canal treatment *** Pulpotomy — the opening of the pulp chamber of the tooth to allow an infection to drain; usually a precursor to a root canal *** Pulpectomy — the removal of the pulp from the pulp chamber to temporarily relieve pain; usually a precursor to a root canal ** Apicoectomy — a root-end resection. Occasionally a root canal alone is enough to relieve pain and the end of the tooth, called the apex, is removed by entering through the gingiva and surgically extracting the diseased material. * Prosthodontics (dental prosthetics) ** Crown (caps) — artificial covering of a tooth made from a variety of biocompatible materials, including CMC/PMC (ceramic/porcelain metal composite), gold or ...

Functional Zoning
Functional zoning or functional city zoning is a method used for dividing land use by its function. Typically, land use is divided in two ways, by its function and by its physical characteristics. An example of functional zoning would be an area that has designated zones based on a function such as an industrial zone, a recreational zone and a residential zone. An example of an area zoned by its physical characteristics is defined in terms of characteristics like development density, minimum lot size, and building coverage, placement and height. Functional zoning tends to create or increase car dependency, while mixed-use zoning tends to enable walking, making it more sustainable Specific definitions of sustainability are difficult to agree on and have varied in the literature and over time. The concept of sustainability can be used to guide decisions at the global, national, and individual levels (e.g. sustainable livin .... It has been criticized for causing the squandering o ...

Upper Canine Teeth
In mammalian oral anatomy, the canine teeth, also called cuspids, dog teeth, or (in the context of the upper jaw) fangs, eye teeth, vampire teeth, or vampire fangs, are the relatively long, pointed teeth. They can appear more flattened however, causing them to resemble incisors and leading them to be called ''incisiform''. They developed and are used primarily for firmly holding food in order to tear it apart, and occasionally as weapons. They are often the largest teeth in a mammal's mouth. Individuals of most species that develop them normally have four, two in the upper jaw and two in the lower, separated within each jaw by incisors; humans and dogs are examples. In most species, canines are the anterior-most teeth in the maxillary bone. The four canines in humans are the two maxillary canines and the two mandibular canines. Details There are generally four canine teeth: two in the upper (maxillary) and two in the lower (mandibular) arch. A canine is placed laterally to ...

Incisor
Incisors (from Latin ''incidere'', "to cut") are the front teeth present in most mammals. They are located in the premaxilla above and on the mandible below. Humans have a total of eight (two on each side, top and bottom). Opossums have 18, whereas armadillos have none. Structure Adult humans normally have eight incisors, two of each type. The types of incisor are: * maxillary central incisor (upper jaw, closest to the center of the lips) * maxillary lateral incisor (upper jaw, beside the maxillary central incisor) * mandibular central incisor (lower jaw, closest to the center of the lips) * mandibular lateral incisor (lower jaw, beside the mandibular central incisor) Children with a full set of deciduous teeth (primary teeth) also have eight incisors, named the same way as in permanent teeth. Young children may have from zero to eight incisors depending on the stage of their tooth eruption and tooth development. Typically, the mandibular central incisors erupt first, followed ...

Frenectomy
A frenectomy is the removal of a frenulum, a small fold of tissue that prevents an organ in the body from moving too far. It can refer to frenula in several places on the human body. It is related to frenuloplasty, a surgical alteration in a frenulum. Done mostly for orthodontic purposes, a frenectomy is either performed inside the middle of the upper lip, which is called labial frenectomy, or under the tongue, called lingual frenectomy. Frenectomy is a very common dental procedure that is performed on infants, children, and adults. A similar procedure frenulotomy is where a tight frenulum may be relieved by making an incision in the tight tissue. Types There are several frenula that are associated with types of frenectomy: * Genital frenectomy (other), Genital frenectomy can be performed to remove frenulums from genitalia * Lingual frenectomy (of the tongue) as a treatment for ankyloglossia (tongue-tie) * Labial frenectomy (of the lip) is very common with patients unde ...

Osteoplasty
Osteoplasty is the branch of surgery concerned with bone repair or bone grafting. It is the surgical alteration or reshaping of bone. It may be used to relieve pain associated with metastatic bone disease. Percutaneous osteoplasty involves the use of bone cement to reduce pain and improve mobility. Resection osteoplasty is used in joint preserving surgery on the hip and thigh bones.Luca Pierannunzii, MD; Marco d'Imporzano, MTreatment of Femoroacetabular Impingement: A Modified Resection Osteoplasty Technique Through an Anterior Approach ''Healio Orthopedics'' (February 2007, Vol 30, Issue 2).

Gingivectomy
Gingivectomy is a dental procedure in which a dentist or oral surgeon cuts away part of the gums in the mouth (the ''gingiva''). It is the oldest surgical approach in periodontal therapy and is usually done for improvement of aesthetics or prognosis of teeth. By removing the pocket wall, gingivectomy provides visibility and accessibility for complete calculus removal and thorough smoothing of the roots, creating a favourable environment for gingival healing and restoration of a physiologic gingival contour. The procedure may also be carried out so that access to sub-gingival caries or crown margins is allowed. A common aesthetic reason for gingivectomy is a gummy smile due to gingival overgrowth. Indications Elimination of suprabony fibrous and firm pockets Gingivectomy is the primary treatment method available in reducing the pocket depths of patients with periodontitis and suprabony pockets. In a retrospective comparison between different treatment approach to periodonti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Furcation Defect
In dentistry, a furcation defect is bone loss, usually a result of periodontal disease, affecting the base of the root trunk of a tooth where two or more roots meet (''bifurcation'' or ''trifurcation''). The extent and configuration of the defect are factors in both diagnosis and treatment planning.Ammons WF, Harrington GW: Furcation, The Problem and Its Management. In Newman, Takei, Carranza, editors: ''Carranza's Clinical Periodontology'', 9th Edition. Philadelphia: W.B. Saunders Co. 2002. page 826-7. A tooth with a furcation defect typically possessed a more diminished prognosis owing to the difficulty of rendering the furcation area free from periodontal pathogens. For this reason, surgical periodontal treatment may be considered to either close the furcation defect with grafting procedures or allow greater access to the furcation defect for improved oral hygiene. Root trunk length The distance between the cementoenamel junction (CEJ) and the furcation entrance is called t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Interdental Papilla
The interdental papilla, also known as the interdental gingiva, is the part of the gums (gingiva) that exists coronal to the free gingival margin on the buccal and lingual surfaces of the teeth A tooth ( : teeth) is a hard, calcified structure found in the jaws (or mouths) of many vertebrates and used to break down food. Some animals, particularly carnivores and omnivores, also use teeth to help with capturing or wounding prey, tear .... The interdental papillae fill in the area between the teeth apical to their contact areas to prevent food impaction; they assume a conical shape for the anterior teeth and a blunted shape buccolingually for the posterior teeth. A missing papilla is often visible as a small triangular gap between adjacent teeth. The relationship of interdental bone to the interproximal contact point between adjacent teeth is a determining factor in whether the interdental papilla will be present. If greater than 8mm exist between the interdental bone and t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crown (dentistry)
In dentistry, a crown most commonly refers to a dental cap, a type of dental restoration that completely caps or encircles a tooth or dental implant. A crown may be needed when a large cavity threatens the health of a tooth. 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 restorative material requiring time-consuming fabrication under intense heat, such as casting metal or firing porcelain, that would not be possib ...

Crown Lengthening
Crown lengthening is a surgical procedure performed by a dentist, or more frequently a specialist periodontist. There are a number of reasons for considering crown lengthening in a treatment plan. Commonly, the procedure is used to expose a greater amount of tooth structure for the purpose of subsequently restoring the tooth prosthetically. However, other indications include accessing subgingival caries, accessing perforations and to treat aesthetic disproportions such as a gummy smile. There are a number of procedures used to achieve an increase in crown length. Biomechanical considerations Biologic width Biologic width is the distance established by "the junctional epithelium and connective tissue attachment to the root surface" of a tooth. The concept was first published by Ingber JS, Rose LF and Coslet JG. - The "Biologic Width"—A Concept in Periodontics and Restorative Dentistry in 1977 in the Alpha Omegan. It was based on cadaver measurements by Gargiulo, Wentz and Or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surgery
Surgery ''cheirourgikē'' (composed of χείρ, "hand", and ἔργον, "work"), via la, chirurgiae, meaning "hand work". is a medical specialty that uses operative manual and instrumental techniques on a person to investigate or treat a pathological condition such as a disease or injury, to help improve bodily function, appearance, or to repair unwanted ruptured areas. The act of performing surgery may be called a surgical procedure, operation, or simply "surgery". In this context, the verb "operate" means to perform surgery. The adjective surgical means pertaining to surgery; e.g. surgical instruments or surgical nurse. The person or subject on which the surgery is performed can be a person or an animal. A surgeon is a person who practices surgery and a surgeon's assistant is a person who practices surgical assistance. A surgical team is made up of the surgeon, the surgeon's assistant, an anaesthetist, a circulating nurse and a surgical technologist. Surgery usually spa ...
