There are techniques that supported by elements such as Digital Smile Design (DSD) 9, wax up and mockup5 offer excellent, predictable aesthetic results, with the option of choosing different materials that are available to all our patients from composite resin to better than we find today; the porcelain clinical case: A 25-year-old female patient who goes to a dental office for teeth whitening, when diagnosing the case, the presence of diastema was observed in the upper centers, as well as anomalies regarding aesthetic smile parameters such as pigmentation, proportions , incisal edge line, among other things. Diagnostic waxing, mockup and photographs were performed to evaluate the result. The treatment plan consisted of 6 resin veneers made with the fluid resin injection technique through a transparent silicone matrix (Flow injection technique). RESULTS: The prognosis of the case is considered favorable, taking into account that the treatment with Resins is not definitive, however functional and aesthetic results were achieved properly. Conclusions: There are several treatment alternatives for the solution of aesthetic problems, which adapt to the possibilities of each patient, the mockup is a necessary tool for obtaining predictable treatments. The fluid resin injection technique is a good aesthetic and functional treatment, which sometimes does not require the minimum wear of the teeth to be treated.","PeriodicalId":300616,"journal":{"name":"ECORFAN Journal Bolivia","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129962500","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These compounds are\u0000classified as polyalcohols and are widely used in the food\u0000and beverage industry to replace common sugar.\u0000However, their consumption is not currently regulated,\u0000and excessive use leads to consequences in the body such\u0000as increased blood glucose levels. Graphene oxide (OG)\u0000inks were prepared, which were deposited on vitreous\u0000carbon (CV) electrodes, followed by enzymatic\u0000immobilization. The detection capacity of the biosensors\u0000was evaluated applying electrochemical techniques.
