Abstract

Background: Composite resin is filling material that used in dentistry fieldbecause of good aesthetic. Use of fiber as reinforced composite resin (FRC)begins to be developed because it has a lot of functions, such as increasestrength, stiffness, material hardness from fracture, and decrease shrinkage.Fiber composite resin has syntetic characteristic and needs chemical processalso has an expensive price. Therefore, natural fiber is easier to find, cheaper and can be developed as an alternative substitute of syntetic fiber. One of the natural alternative is sisal fiber. This study aims to know the effect of volume fraction of sisal fiber to composite resin flexural strength with sisal fiber concentration 1%, 2%, 3%, 4%.Method: This study was true experimental with post test only control groupdesign which divided into 4 groups RK+FS 1% (K1), RK+FS 2% (K2), RK+FS3% (K3), RK+FS 4% (K4). The data was analized using one way ANOVA assayand Post Hoc with significant degree 5%.Results: Mean of flexural strength sum K1=50,87 MPa, K2=42,96 MPa,K3=33,94 MPa, K4=24,32 MPa. Result of one way ANOVA assay showed valuep=0,000. Result of further assay Post Hoc showed K1 with K2 p=0,002, K1 withK3 p=0,000, K1 with K4 p=0,000, K2 with K3 p=0,001, K2 with K4 p=0,000, K3with K4 p=0,000.Conclusions: Concluded that there is good effect of sisal fiber volume fractionto composite resin flexural strength. Flexural strength RK+FS 1% has higherstrength than RK+FS 2%,3%,4%. Sisal fiber could become a natural fiberalternative in dentistry restoration material.

Abstract

Background: One of factor that increases the flexural strenght of fiberreinforced acrylic resin is a fiberglass position . Fiberglass is one of type that can be used in dentistry. The aim of this was to determine the influence of position of fiberglass to the flexural strenght of fiber reinforced acrylic resin.Method: This study was in vitro laboratory experimental. Samples was 16plate spesimens (65x10x2.5mm). The study group was divided into 4 group : 3 groups of fiber reinforced acrylic resin were given fiberglass at the upper, middle, and bottom side and 1 control group of resin acrylic without fiberglass. All of groups would be in the flexural strenght test with a three-point bending test using a universal testing machine.Result: Based on One Way ANOVA test showed that there were significantvalue 0.000 (p<0.05), it concluded that there were significant influencebetween all the groups. Based on the LSD Post Hoc test showed that therewere significant value between all of groups with fiberglass reinforced andcontrol group without fiberglass reinforced. Comparisson between the group that given fiberglass in a upper and middle side with the group that given in bottom side showed value of significant difference (p < 0.05).Conclusion: The result of study was concluded that there was an influenceon the position of fiberglass to flexural strenght of fiber reinforced acrylic resin

Abstract

Fixed bridge and crown restorations are widely utilized in dental practice. The utilization of bridge as a substitute for implants is prevalent in several contexts. The crown preparation procedure has a crucial role in determining the long-term periodontal tissue health. Under-preparation frequently manifests in many clinical circumstances, resulting in the thickening of the prosthetic crown in the cervical region. The accumulation of plaque in subgingival preparations is an often seen issue. Given the progressive advancements in material technology and manufacturing procedures, it is imperative to critically evaluate the continued suitability of chamfer and shoulder preparation techniques in contemporary practice. This is particularly relevant when considering restorations involving subgingival preparation edges. The objective of this study is to examine the utilization of knife-edge modified subgingival preparation procedures and monolithic zirconia restorative materials as potential strategies for the maintenance of periodontal and esthetic tissues over an extended length of time

Abstract

Background: Most of dental implants are accompanied by guided bone regeneration (GBR) procedures. Collagen membrane which is the most widely used type of membrane in the GBR procedure has the disadvantage of not having antimicrobial properties, old bone formation, easy to tear, and soft so that it does not maintain the dimensions of the augmentation area. Bombyx mori L. fibroin has good mechanical properties and has the potential to be used as a pharmaceutical material that is biocompatible, antimicrobial, and stimulates bone growth. The aim of this study was to analyze the effect of Bombyx mori L. fibroin coating on the mechanical properties of collagen membranes. Method: The samples consisted of the control group (group A) and the treatment group, the collagen membrane was coated using the Bombyx mori L dip-coating fibroin technique, namely group B (1 time coating process), group C (2 times coating process) and group D (3 times the coating process). Statistical analysis used one-way ANOVA (p

Abstract

Background: Bone reconstruction in a dental implant is a big challenge work, especially in a large defect where there was no anatomic supporting tissue. Nowadays there is no ideal membrane to be considered. In this case, titanium, even though second surgery is needed, seems the best choice as it can maintain its shape under the flap. Titanium may cause a membrane perforation on the mucosa in a thin gingival phenotype case. Purpose: This case report aimed to present a bone reconstruction procedure using 3D titanium membranes for dental implant treatment. Case. A 37 years old male patient came to the clinic with a chief complaint was a defect on his anterior tooth. Intraoral examination revealed an 11 fractured and luxated. Methode and Treatment Result: We used an allograft covered with 3D Titanium mesh after loading a dental implant. At the end of the surgery, a resorbable membrane was applied. Conclusion: It is concluded that 3D Titanium mesh can be an application for anterior bone reconstruction.
