opposing arch dental definition

Their enamel is thin, with an average of 0.5mm thickness compared to 1.0mm or more in the permanent dentition. core buildup: the replacement of a part or all of the crown of a tooth whose purpose is to provide a base for the retention of an indirectly fabricated crown. Restorations, which are fixed for the patient (possibly screw-retained or semi-permanently cemented), but are designed to be removable by the dentist, are called "operator-removable". The dental arch, also known as the dental curve or jawline, is an important part of the human mouth that helps form the entire facial structure. On sectioned surfaces, the tissue is soft and gelatinous or rubbery, may be lobulated, and there is destruction and replacement of normal bony tissue with a thin shell of periosteal new bone.10,26 Malignant masses may infiltrate surrounding soft tissues with more marked bony reaction. filling: A lay term used for the restoring of lost tooth structure by using materials such as metal, alloy, plastic or porcelain. ancillary: Subordinate or auxiliary to something or someone else; supplementary. (b) A procedure whose outcome is, by intent, not subject to change arising from subsequent delivery of another procedure; a change may occur if the dentist determines that a change in the patients clinical condition warrants delivery of another or alternative procedure. composite: A dental restorative material made up of disparate or separate parts (e.g. clinical crown: That portion of a tooth not covered by tissues. accession: Addition of a test specimen, previously collected by a health care provider, to a laboratory specimen collection; recording of essential specimen identification data in a laboratory-maintained file in chronological order of laboratory specimen acquisition; assignment to the specimen of an identification code. Stretching the PDL applies a pull on the alveolar bone and stimulates the osteoblasts to deposit new bone. mesial: Nearer the middle line of the body or the surface of a tooth nearer the center of the dental arch. [Note: The appropriate type of crossbite can be specified by identifying the teeth or jaws that deviate the most from their ideal position (e.g. Examples include use of a papoose board, education or anxiety relief techniques. *metals of the platinum group are platinum, palladium, rhodium, osmium and ruthenium. amalgam: An alloy used in direct dental restorations. Supernumerary teeth occur at higher frequency in males than in females (Brook, 1984). resin and quartz particles). Upper premolars generally have three roots whereas lower premolars have two (see Remane, 1960, for a detailed count of roots of teeth in various species). FIGURE 4.7. local anesthesiathe elimination of sensation, especially pain, in one part of the body by the topical application or regional injection of a drug. The single root is usually conical. The primary teeth are smaller and have a shallower anatomy than their successors. interproximal: Between the adjoining surfaces of adjacent teeth in the same arch. evulsion: Separation of the tooth from its socket due to trauma. Once tooth movement has been accomplished, the tooth or teeth must be maintained in their desired positions; in veterinary orthodontics this is usually 2 to 4 weeks. The lingual surfaces of tooth crowns are usually hidden from view when a person smiles. Current Procedural Terminology (CPT): A listing of descriptive terms and identifying codes developed by the American Medical Association (AMA) for reporting practitioner services and procedures to medical plans and Medicare. transdermala technique of administration in which the drug is administered by patch or iontophoresis through skin. Study model is another term used for such a replica. when a crossbite is mainly due to a narrow maxillary arch the correct The anterior portion of molar and premolar crowns and the medial parts of canines and incisors are called the mesial parts of these teeth. Incisors are abbreviated I and are numbered from the midline. The tooth is prepared and then the tray is loaded with the impression material. Step 2: Verify adequate occlusal and incisal clearance by seating the posterior provisional sections to check for anterior clearance (Fig. Loops may be placed on the buccal or palatal/lingual surface with a preference for the side least likely to cause occlusal interference. malignant: Having the properties of dysplasia, invasion, and metastasis. WebAny tooth contact that inhibits the remaining occluding surfaces from achieving stable and harmonious contacts; Any undesirable occlusal contact Maximal intercuspal position the complete intercuspation of the opposing teeth,independent to condylar position Directional terms and planes of reference for human teeth. Buccal: (pronounced buckle) opposite of lingual; toward the cheeks; usually reserved for premolars and molars. simple fracture: Break in bone which is not exposed to external contamination. for a total of 32 teeth. Complete Dentures Single Dentures Opposing Natural Dentition Therefore, if the opposing arch is natural teeth, usually more implants are required and vice-versa. 9-3, D) (requires the greatest amount of force). A narrow ingress into this space acts as a valve, allowing partially masticated feed into the space; however, no egress occurs. compound fracture: Break in bone which is exposed to external contamination. 1. lingual: Pertaining to or around the tongue; surface of the tooth directed toward the tongue; opposite of facial. a structure of bowlike or curved outline. The magnitude of the force applied to the crown of the tooth is critical.

So for example if they say extract a first molar tooth on the upper arch but it may cause over-eruption of the opposing tooth in the opposing arch, it mean temporary: a restoration or prosthesis placed for a shorter time interval for use while a definitive restoration or prosthesis is being fabricated see interim and provisional. rebase: Process of refitting a denture by replacing the base material. implantation, tooth: Placement of an artificial or natural tooth into an alveolus. One of these measurements is tooth-size discrepancy, which is defined as disproportionate sizing of opposing teeth [].Bolton overall and anterior ratios between opposing teeth should be normal to ensure ideal Derek C. Knottenbelt OBE, BVM&S, DVM&S, Dipl ECEIM, MRCVS, Donald F. Kelly MA, BVSc, PhD, MRCVS, FRCpath, Dipl ECVP, in Equine Dentistry (Third Edition), 2011. implant case the fixture that is placed between the implant body (aka implant post) and the restorative prosthesis (e.g., single crown; denture). Labial: opposite of lingual; toward the lips; usually reserved for incisors and canines. apexogenesis: Vital pulp therapy performed to encourage continued physiological formation and development of the tooth root. P2, P3, and P4, of the original four primitive mammalian number. Four classes of teeth (Butler, 1978) are evident in each quadrant of higher primates (Figure4.6). Maryland bridge: Fixed partial denture featuring retainers which are resin bonded to natural teeth that serve as an abutment. These studies (Swindler, 2002) have shown that premolars are lost from anterior to posterior along the tooth row and that the premolars retained in living primates are the last of the original premolars. There is no scheduled replacement, although some maintenance may be necessary (e.g., cleansing; replacement of the replaceable component of an attachment), procedures that are documented with their applicable codes. by report: A written description of the service provided that is prepared when the term "by report" is included in a procedure code nomenclature; must be part of the patients record and included on the claim submission. A wad of chewing tobacco is sometimes wedged between the cheek and the buccal surfaces of the molars of American baseball players. The correction of malocclusions in animals has moral, ethical, and legal implications. The working arch is the arch of teeth in the oral cavity that is being prepared for the fixed protheses. For example, the tooth being prepared is the lower left 6. This means the working arch is the lower arch. The opposing arch is the arch of teeth in the oral cavity that is opposite the working arch. abutment: A term with different meanings depending on the clinical scenario. cavity: Missing tooth structure. Commonly, the letter d appears before the letter indicating the tooth, although deciduous teeth are sometimes indicated simply using lower typecase (i, c, p or pm, or m) instead of the capital typecase (I, C, P or PM, or M) used to indicate permanent teeth. The principle challenge is to develop bilateral balanced stress breaker: That part of a tooth-borne and/or tissue-borne prosthesis designed to relieve the abutment teeth and their supporting tissues from harmful stresses. residual rootRemaining root structure following the loss of the major portion (over 75%) of the crown. exclusions: Dental services not covered under a dental benefit program. For example, the tooth that is being (Words and terms in bold are defined within this glossary. supernumerary teeth: Extra erupted or unerupted teeth that resemble teeth of normal shape. non-intravenous: See definition under anesthesia. A baby whose molar erupts ahead of the incisor presents a highly abnormal situation, either of syndromic or systemic cause (e.g., one of the first symptoms of histiocytosis X disease is the premature eruption of a posterior tooth). Published by Houghton Mifflin Company. prosthesis: Artificial replacement of any part of the body. An accurate impression of your teeth and gums will help your dentist recreate a model of your dental keeper or keeper assembly: Any one of various devices used for keeping something in position (Glossary of Prosthodontic Terms, 9th Edition; Academy of Prosthodontics); see precision attachment. The upper arch opposes the lower, and When the arches touch, we call this the bite. The alignment between the upper and lower teeth Deciduous teeth are generally smaller than their successor teeth. Another consideration pertains to the symmetry of the dentition. open reduction: Re-approximation of fractured bony segments accomplished through cutting the adjacent soft tissues and bone to allow direct access. The Ness Visual Dictionary of Dental Technology - ptc-dental.com Biopsy is essential. deep sedation: See definition under anesthesia. medicament: Substance or combination of substances intended to be pharmacologically active, specially prepared to be prescribed, dispensed or administered by authorized personnel to prevent or treat diseases in humans or animals. The dual arch impression procedure should only be used when certain criteria are met. See graft. indigent: Those individuals whose income falls below the poverty line as defined by the federal Office of Management and Budget (OMB). A cavity may be due to decay, erosion or abrasion. See semi and precision attachment. Some literature may therefore incorrectly refer to premolars as P1, P2, and P3 when they should accurately be described as P2, P3, and P4. It is retained by luting cement or mechanical means. equilibration: Reshaping of the occlusal surfaces of teeth to create harmonious contact relationships between the upper and lower teeth; also known as occlusal adjustment. Such materials can include cytokines, growth factor, or vaccines, but do not include any actual hard or soft tissue graft material. 1) It should be used with an stable dentition (Braley Class I ) and the single prepared unit should have intact teeth adjacent to it.
