As with most pain disorders, a high prevalence of depression and anxiety is associated with TMD. Research has shown that selective serotonin reuptake inhibitors (SSRIs), the first-line drug therapy for major depressive disorder, may not be suitable for TMD patients because SSRIs can induce teeth-grinding, otherwise known as bruxism.

Selective Breeding. Selective breeding (or artificial selection) is a process in which rats are bred for a particular trait or phenotype. This technique has long been established in experimental medical research with first reports of selective breeding lines …

Fine grinding or milling reduces the particle size down to as low as 1.0 micrometer (µm) (4 x 10-5in.) in diameter. Ball mills are the most commonly used piece of equipment for milling. However, vibratory mills, attrition mills, and fluid energy mills also are used. Crushing and grinding typically are dry processes; milling may be a wet or dry ...

Articles About grinding. Articles are sorted by RELEVANCE. Sort by Date.. 1 Prediction of Surface Zone Changes in Generating Gear Grinding (March/April 2015). One process for hard finishing gears is generating gear grinding.Due to its high process efficiency, generating gear grinding has replaced other grinding processes such as profile grinding in batch production of small- and …

grinding, process by which surface material is removed from an object, usually metal, by the abrasive action of a rotating wheel or a moving belt that contains abrasive grains. A

cutting which will obscure the true etch pattern. Proper cutting and grinding techniques must be employed to avoid any damage from these sources. 1-2.2 Copper-Containing Macroetchants for Primary Structure Macroetching steels with etchants containing copper ions predates the develop-ment of hot-acid etching.

selective grinding. English focus texts. Diamond instruments; Translate. punktförmiges Einschleifen; Korrekturschleifen; Definition from Glossary. The intentional alteration of the occlusal surfaces of teeth to change their form. Want to give it a try ..... or need professional advice?

The selective grinding procedure is an irreversible process for reshaping teeth by accurately modifying specific areas of the crown according to a previously established pattern, in order to remove interferences and premature contacts. ... New definition for relating occlusion to varying conditions of the temporomandibular joint. J. Prosthet. Dent.

Selective Hedging. The practice of making investments that reduce the risk to part of one's portfolio, but not the whole portfolio. Alternatively, selective hedging may involve making offsetting investments on the whole portfolio, but only at certain times. Selective hedging carries higher risk than other hedging strategies simply because it ...

Selective grinding of the tooth surfaces to produce occlusal adjustment has been described as a valid adjunct to orthodontic treatment for improving the overall contact pattern of the teeth [19, 20].
