Background An impotant step in maintaining smile to replace missing teeth. When teeth are missing, the remaining ones can change position, drifting the surruonding space. Teeth that are out of position can damage tissues in the mouth. A denture helps you properly chew food, a diffi cult task when you are missing teeth. In addition, a denture may improve speech and prevent sagging face by providing support for lips and cheeks. A partial denture is suitable for those who have some natural teeth remaining.While missing one and two adjacent teeth can often be best restored fi xed bridge or implant, partail denture work best to replace multiple missing teeth. Removable partial denture usually consist of replacement teeth attached to pink or gum- colored plastic bases, which are connected by framework. Removable patial dentures attach to your natural teeth with metal clasp or devices called precision attachment. Precision attachments are generally more estetic and cost more than those metal clasps. Denture with metal and wrought wire clasps are generally more fi t and stay in place much better than (provisional) denture. Objective The main purpose of this study is to develop of provisional denture. Materials and Methods This study has been used to study medicine. Enerel dental clinic served 1481 people whom they were made denture between 2003 and 2005. from those people were made denture with wrought clasp for 60 people. By experimental study, jawing activity test has been used by I.S.Rubinov method. Results Denture with wrought clasp needs was increasing gradually until 56 percents in 2003, 82.1 percents in 2004, 93 percents in 2005. A large number of denture with wrought clasp was made 32.4 percent of maxilla, 47.1 percent was mandible but this denture were used and suited for people 78 percent, 22 percent of people who made those type of denture did not and uncomfortable for them. Denture with wrought clasp jawing activity was 1.920.13 seconds and jawed things weight was1.89 0.1, lost of jawing activity was 2.691.44 (=0.001). Conclusion Method of denture with wrought clasp is simpler and nearly minted removable denture.

Introduction: This plants distributed about 2500 species in worldwide and 69 species of those grow in Mongolia. In case of medicinal application of this plant is commonly used traditional medicine in European and Asian. For example, the different preparations of Astragalus mongholicus root, the most commonly used Astragalus species in Chinese medicine.

It is also used to soothe a purulent inflammation, for wound-healing, to treat lung fever, oliguria and hemorrhoids. It is an ingredient of the following traditional prescription: Jurur-6 Chemical constituents: Root contains flavonoids: formononetin, 3-hydroxy-formononetin, 2,3- dihydroxy- 7,4-dimethoxyflavone, 7,3-dihydroxy-4-methoxyflavone 7-O- glucoside, 7,3-dihydroxy-4- dimethoxyflavone, saponins: astragaloside I-X, isoastragaloside I-IV, polysaccharides, Above- ground parts contain astragaloside quercetin, isorhamnetin, rhamnocetin, isorhamnetin 3-b-Dglucopyranoside, propingoside, coumarin, tannins, and saponins. Qualitative and quantitative assays: Flavonoids in the plant are identified by cyanidin reaction and reaction with lead tetraacetate. Total flavonoid content is determined by spectrophotometry at 430 nm and calculated as quercetin. Qualitative and quantitative standards: Loss on drying, 8.0%. Organic matter, not more than 0.5% and mineral matter, not more than 1.0%. Total flavonoid content, not less than 3.0%.
