Background: The dentist who handles a broken acrylic resin denture base case will send the denture to be repaired by a dental technician in the dental laboratory. The transfer of work is likely to pose a risk of cross-infection (for example AIDS, hepatitis, tuberculosis, pneumonia, and herpes. Purpose: To transfer science and technology based on community needs objectively to get a strong foundation in implementing health management for dental technicians. Methods: Training on how to use disinfection materials as well as participatory counseling using slides through LCD projectors, and using props along with interactive discussions and also mentoring when trainees take disinfection measures. Results: The implementation includes 3 activities, that is counseling, training and monitoring Counseling is carried out by providing knowledge about how to disinfect dentures, then training in how to do disinfection, the way is to train dental technicians to disinfect using chlorhexidine by spraying on the denture surface, then monitored. Conclusion: So far the dental laboratory has not carried out any disinfection at the time of denture repair. With counseling and training in this community partnership program, dental technicians know the importance of disinfection denture to prevent cross infection, so that it will then do it.
Background: single complete denture is complete denture where its antagonist there tooth original good in part or else entirely. Besides that on case this there bulge tuber maxilla more big of the normal size of course only will complicate at the stage of preparation of teeth and also take effect on retention, stability, and comfort. Objective: to discuss about technique manufacture single complete denture with a large tuber maxilla. Review of literature: Single complete denture is a complete denture in which the antagonistic teeth can be either partial or whole natural teeth. Whereas complete denture is a complete maxillary and mandibular denture that is used if both jaws do not have natural teeth. To get good inclination and occlusal surface can do with Swenson technique and Yurkstas technique which is use a compensating curve template to determine the occlusal views of Wilson’s curve and spee curve. Conclusion: in the making single complete denture, moment preparation tooth there difficulty because have a big maxilla and need a lot of grinding on dental elements and additions anasir second premolar teeth for get aesthetic and functional is good, too take effect to retention and stability.
Background: Acrylic resin is the most commonly used denture base material. One disadvantage is that it can absorb water that can cause changes in dimensions. Changes in the dimensions of acrylic resin are influenced by processing acrylic resin. At present injection molding techniques are known to be better than compression molding. Dimension changes due to water absorption occur in the first 7 days and interval intervals of up to 12 days. Purpose: this study was to determine whether immersion of acrylic resin with Injection molding techniques had an effect on changes in dimensions. Method: The study was conducted on acrylic resin test rods with a size of 25 mm x 25 mm x 5 mm. by using injection molding techniques. Acrylic resins are immersed in water for 24 hours, 48 hours and 12 days. Changes in dimensions are measured using a caliper with an accuracy of 0.01 mm. Statistical analysis was performed using the normality test, homogeneity test, and ANOVA test. Results: this study found that there was no change in dimensions of acrylic resin with water-immersed injection molding techniques 24 hours, 48 hours and 12 days. Conclusion: That immersion of acrylic resin in water at 24 hours, 48 hours, and 12 days with injection molding techniques did not affect changes in dimensions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
