According to (GPT-9) the action of pouring or injecting a flowable material into a refractory mold. The object formed is also referred to as “a casting”. There are various steps of fabrication of a simple full metal crown. Casting failures of alloys in dental technology should be the exception, not the rule. They have to be detected in time and associated with possible causes. For the experimental part base metal alloys single tooth restorations were achieved using the conventional lost wax process for casting in order to be evaluated. Some casting defects obtained during the experimental part are exemplified: incomplete castings, absence of the castings, voids, distorsions, nodules, porosities. Selecting the appropriate casting techniques for each alloy and dental restoration and accurate following of the technologycal steps are essential to avoid casting defects.

The article elaborates on the possibility of increasing cotton yields by improving the agrophysical, agrochemical and microbiological properties of fallow soils by deep tillage at different depths between rows of cotton grown on irrigated fallow soils in the southern regions of the Republic of Uzbekistan. In variants 4 and 5 of the experiment, an increase in cotton yield was observed as a result of improved agrophysical, agrochemical and microbiological properties of the soil when cotton was cultivated at depths of 26-28 cm and 30-32 cm, respectively. In the experiments, when the cotton row spacing was loosened to a depth of 30-32 cm, the mass volume of the soil in the drive and subsoil layers decreased by 0,02-0,03 g/cm3, porosity by 2,0-2,1%, water permeability by 100-120 m3/ha increase in; humus content was higher by 0,004%, nitrogen content was higher by 0,007%, and phosphorus content was higher by 0,006%; As a result of the rapid development of the cotton root system, the efficiency of moisture and nutrient utilization has increased, and an additional 4-5 ts/ha of cotton has been proven to be obtained. The best results are obtained by cultivating cotton at a depth of 30-32 cm between rows. additional yield was obtained.

Dewaxing is the process of removing wax from the ceramic mould which is covered with wax or melting the wax pattern out of ceramic mould. The heating should be rapid enough to minimise expansion of the wax in order to avert ceramic mould cracking and dimensional alteration. The current survey considers the benefits of helping out Dewaxing through the microwave over customary autoclave strategy for Dewaxing. The Microwave Dewaxing is feasible, fundamentally diminishing the fuse of soil and water, which is inescapable in the Autoclave Dewaxing process. This research is to utilise the advantages of Microwave Dewaxing and to get more knowledge about Microwave Dewaxing, exploring the efficacy of Microwave Dewaxing, and to know the efficiency of Microwave Dewaxing. This is a review study setting, evaluating the advantages of Microwave Dewaxing technique over Conventional Autoclave Method. Data for the study were collected from search engines like PUBMED, GOOGLE SCHOLAR, MeSH, Cochrane and Semantic Scholar. A total number of 35 articles were searched and a total number of 29 articles were selected. A number of articles with known concepts are 7, a total number of 8 articles with recent updates. The data obtained from the present study concludes that it may be useful for practitioners to make high quality dentures with minimal time expenditure when compared to Conventional Autoclave Dewaxing methods. This research will also be helpful to get more knowledge about the advantages of Microwave Dewaxing over Convention Autoclave Dewaxing systems.
