Maryland bridge: Fixed partial denture featuring retainers which are resin bonded to natural teeth that serve as an abutment. removable partial denture: A removable partial denture is a prosthetic replacement of one or more missing teeth that can be removed by the patient. A form of dental radiograph that may be taken with the long axis of the image oriented either horizontally or vertically, that reveals approximately the coronal halves of the maxillary and mandibular teeth and portions of the interdental alveolar septa on the same image.

The stellate cellular shape is maintained in areas of secondary fibrosis10 In the mandibular myxoma, the nuclei were ovoid and vesicular, with one or more indistinct nuclei, and the mitotic rate was low.26 In malignant neoplasms, there is higher cellularity, with larger, more pleomorphic tumour cells.10 No areas of bone or cartilage formation should be noted.10,11 Extensive resorption of adjacent bone may be seen, i.e. 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.

These tumors are very unpredictable in behavior; some are slow growing and remain relatively benign; others are highly aggressive and so carry a hopeless prognosis. This is known as the retention period. This causes a delay in the orthodontic movement process. filling: A lay term used for the restoring of lost tooth structure by using materials such as metal, alloy, plastic or porcelain. when a crossbite is mainly due to a narrow maxillary arch the correct [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. He has over 12 years practical experience as a dental technician and has been working as a specialist translator (German - English) for dentistry and dental technology for more than 25 years. Osteoclasts and osteoblasts occur in the alveolar bone. The range of species variability in premolars is greater than in other teeth.

Thus, the premolars present in living primates are P2, P3, and P4 if the primate species has three premolars and P3 and P4 if the primate has only two premolars. In addition to each tooth in the dental arcade being designated by a letter and number, the position of the number for a given tooth is used to indicate the dental arch in which the tooth appears. They are followed by the maxillary central incisors (812months), the maxillary lateral incisors (913months), and the mandibular lateral incisors (1016months). occlusal surface: A surface of a posterior tooth or occlusion rim that is intended to make contact with an opposing occlusal surface.

WebThe opposing arch Those with natural teeth have increased bite force. coping: A thin covering of the coronal portion of the tooth usually without anatomic conformity. The combined destruction and proliferation of tumor tissue creates obvious distortion of the maxilla, with secondary nasal and sinus obstruction. In some species, particularly the smaller New World primates, dental maturity may be accelerated and may precede skeletal maturity. Note: The term follow-up care is interchangeable with a variety of similar terms (e.g., normal post-operative follow-up; routine follow-up [or post-delivery or post-operative] care). Removable restoration saddles are often connected by a metal base (frequently fabricated using CrCo), in the upper jaw possibly using a large connector (transverse connector) and in the lower jaw using a lingual bar.
