The lingual surfaces of tooth crowns are usually hidden from view when a person smiles. WebComplete denture with opposing occlusal plane discrepancy restored with fixed In this patient the occlusal plane of the mandibular arch was idealized with fixed restorations.Note: The cuspal inclinations of the posterior maxillary dentureteeth are relatively flat and the compensating curve is 15 to 20degrees. In Old World monkeys, the molar crowns display strong transverse ridges between pairs of cusps and constriction between mesial and distal pairs of cusps resulting in the closely approximated cusps forming two distinct ridges which are oriented lingualbuccally. The cheek teeth of primates are used for mastication and are divided into two groups based on evolutionary development as well as dental morphology. alloplastic: Refers to synthetic material often used for tissue augmentation or replacement. fascial: Related to a sheet or band of fibrous connective tissue enveloping, separating or binding together muscles, organs and other soft tissue structures of the body. apexogenesis: Vital pulp therapy performed to encourage continued physiological formation and development of the tooth root. periodontal disease: Inflammatory process of the gingival tissues and/or periodontal membrane of the teeth, resulting in an abnormally deep gingival sulcus, possibly producing periodontal pockets and loss of supporting alveolar bone. medicament, topical: Pharmacological substance especially prepared to be applied on tissues of the oral cavity. There is, however, considerable variability even between closely related species. Maryland bridge: Fixed partial denture featuring retainers which are resin bonded to natural teeth that serve as an abutment. (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. The dual arch impression procedure should only be used when certain criteria are met. exfoliative: Refers to a thin layer of epidermis shed from the surface. occlusal surface: A surface of a posterior tooth or occlusion rim that is intended to make contact with an opposing occlusal surface. The radiographic appearance can be very similar to osteosarcoma (see above) and squamous cell carcinoma. To save this word, you'll need to log in. Three ceramic onlays (Figure 5) and a 3-unit metal ceramic bridge with metal occlusal surfaces (in order to gain interocclusal distance) were fabricated in the dental laboratory.

Full restorations (full/complete dentures) replace all the teeth in an edentulousjaw (the only prosthetic alternative not involving implants). transitional: The passage or change from one position, state, phase or concept to another (e.g., transitional dentition). root canal - Space inside the root portion of a tooth containing pulp tissue. 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). artificial crown: Restoration covering or replacing the major part, or the whole of the clinical crown of a tooth, or implant. This technique is a continuation of the Ivy loop technique whereby repetitive loops are placed around a minimum of two teeth on either side of the fracture. Learn a new word every day.
