Abstract: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.

Abstract:Background: The low levels of patient satisfaction and confidence in the restoration of the gingival resorption results in impaired quality of life in both functional and psychosocial aspects. It is necessary to manufacture a dental restoration to restore the mastication, phonetic, and aesthetic functions associated with soft tissue repair. Manufacture of gingiva ceramic restorations which are believed to be an alternative to restore the aesthetic function and harmonization of the patient’s teeth. In terms of manufacturing techniques, this restoration has a level of difficulty in achieving a balance between “White aesthetic” and “aesthetic pink”. Objective: This study aims to provide knowledge to the reader of Manufacturing Technique of Metal Ceramic Restoration with Implant-Abutment at Gingival Resorption Case. Reviews: Gingiva ceramic restorations can be used to create esthetic implant-supported restorations when bone and gingival tissues are deficient and surgical replacement of such tissues is not possible. Dental technicians should be able to analyze the three-dimensional shapes of gingival anatomy, color, texture, smile components, the balance of the “pink aesthetic” and “white aesthetic”. Conclusion: Manufacturing Technique of Metal Ceramic Restoration with Implant-Abutment at Gingival Resorption Case including the manufacture of metal coping, oxidation, application of opaque coating, application of the first “white aesthetic” ceramics (Opaque Dentine, Dentine, Enamel and transpa on crown coping restorations), Application of opaque gingiva layer, gingival ceramics build-up "pink aesthetics”, first firing, followed by correction build-up, and second firing, and ends with the glazing process.

Abstract:Background: Ceramic restorations is divided into two kindsnamelyPorcelain Fused to Metal (PFM) and all-ceramic restorations. In ceram spinell is one of the materials needed for manufacturing anterior coping of all ceramic which has better aesthetic than in other in ceram. Methods which have been done are Conventional Slip Cast by application of spinell paste on refractory die manually and CAD/CAM computer-based technique. The difference of mentioned previously methods is few step-in slips cast methods can be performed only by one step CAD/CAM methods. Objective: To discover the differences between Conventional Slip Cast methods and CAD/ CAM methods. Review: Application of CAD/CAM methods has few advantages compared to conventional methods. Since few step-in conventional methods can be performed only one step in CAD/CAM methods. Conclusion: In order to shorten the time in manufacturing spinell all-ceramic, the dental technician may use CAD/CAM methods. Few advantages of CAD/CAM methods compare to slip cast methods are not necessary to do die to block out, die duplication, wetting agent spraying, vitasonic and ultrasonic usage, giving border by ink pen for determining application border, preparing spinell paste for coping application. Those steps all can be performed only by scanning, design, and milling by CAD/CAM methods. Besides that, coping result produced by CAD/ CAM methods has good accuracy due to spinell block utilization which has better homogenous composition.

Abstract:Background: By using T2 weighted image (T2WI) of Magnetic Resonance Imaging (MRI), a radiologist can classify degenerative cervical canal stenosis (DCCS) into three grade, but there is no correlation between stenosis classification with clinical symptoms. It means that radiologist need a new parameter to make an early detection for spinal cord injury (SCI). Objective: Proving decrease of FA and increase of MD at the most proximal level of 2nd grade DCCS patient compared with C1-2. Methods: Cervical MR examination with 15-direction DTI sequens was performed on twenty one patient with neurological signs and symptoms of 2nd grade DCCS. Apparent FA and MD maps were generated on axial plane. The FA and MD measurements in each individual were made at the most proximal level of 2nd grade DCCS and C1-2. Wilcoxon rank sump test was used to compare FA and paired t-test was used for MD. Result : There are significant differences for FA (p = 0,00) and MD (p = 0,00) at the most proximal level of 2nd grade DCCS compared with C1-2. Conclusion: This research shows that FA and MD value at DTI sequens can be used for SCI early detection at 2nd grade DCCS patient
