As the interest for esthetic restoration is increasing, the usage of composite resin is increasing. The usage of composite resin is not limited to anterior teeth but is spreading to posterior area using direct ＆ indirect methods. Generally, dual or chemical cure resin cement has been used for setting composite or porcelain inlay restoration. However, chemical cure resin cement has limited working time and it's difficult to remove excess cement from the tooth and the restoration. The dual cured composite is also difficult to remove from the tooth surface.(omitted)

The demand for tooth-colored restorations has grown considerably during the last decade. Posterior composite restorations have risen in popularity as a result of the development of improved resin composites, bonding systems and operating techniques. A major limitation of direct composite restoration is the difficulty of controlling the polymerization shrinkage. To overcome this limitation, the indirect fabrication of a composite restoration and cementation with resin cement has been advocated. Unfortunately, the current available resin cements with indirect restorations do not always bond to dentin as strongly as dentin adhesive systems bond with direct resin composite restorations. Several procedural strategies have been proposed for indirect composite restoration. In this regard, the rationale for the indication, characteristics and clinical application is described in this paper. As a result, we will try to suggest the evidence-based guidelines for indirect composite restorations by reviewing each available indirect composite products, technical procedure and pronosis.

In case of esthetic restorative procedure with zirconia restoration, we have to use resin cement because of not only just for retention but also esthetic reason. In such a clinical situation, we have to consider two bonding interfaces, one is tooth surface to resin cement and the other is zirconia surface to resin cement. There is well established bonding protocol between tooth surface to resin cement, but bonding protocol of zirconia surface to resin cement is still controversial. In scientific point of view, there are two mechanism for bonding of zirconia restoration.. One is mechanical retention and the other is chemical adhesion. However, we have three different options for bonding of zirconia restoration in clinical situation; 1) Tribo-chemical coating with silica and silane coupling agent 2) Zirconia primer with phosphate chemistry 3) Self-adhesive resin cement with phosphate chemistry.

석조 문화재의 복원을 위하여 우레탄 복원제를 제조하였다. 제조된 우레탄 복원제는 그간 석조 문화재 복원용 재료로 주로 사용해 왔던 에폭시계 복원제 정도의 강한 접착 강도와 인장 강도를 나타내고 있으며, 충진성, 수축성, 도색성 등의 물성 역시 에폭시계 복원제와 유사하게 제조되었다. 특히, 이 우레탄 복원제는 그간 가장 큰 문제점으로 대두되었던 에폭시계 복원제의 황변 현상과 비가역성 문제를 해결함으로서, 석조문화재의 복원의 항구성과 지속적인 안정성을 부여할 수 있을 것으로 보인다. 또 본 복원제를 메움제와 접착제로 직접 적용하여 사용하였으며, 이를 재 용해하여 복원에 사용된 우레탄을 제거할 수 있어 본 복원제의 가역성을 나타내었다. 이 복원제는 작업 환경에 따라 복원자가 가사 시간을 조정할 수 있도록 제조되어 사용의 편리성 또한 증진시켰다. 또 이 복원제는 강한 접착력과 인장 강도를 가지고 있어 석조문화재 이외의 도자기나 금속 문화재 등의 다양한 문화재의 메움제나 접착제로 사용이 가능할 것으로도 사료된다.

The purpose of this descriptive in vitro study were to evaluate the enamel-resin interface of the preventive resin restoration with regard to etching patterns and resin-tag morphology by means of scanning electron microscope. The results were as follows; 1. Three basic etching patterns were appeared simultaneously in a same microscopic section, in concentration between 20-50% phosphoric acid. 2. In 35% orthorhosphoric acid group etched for 60 second, the etching pattern was most prominent and demonstrate closely interdigitated with enamel-resin interface without the evidence of microspace, and the resin tags were longest ranged from 10-15 um in length. 3. This pattern of interface could reduce the incidence of marginal leakage and 2ndary caries formation. 4, The preventive resin restoration could serve as sealing a questionable occlusal surface.

The improvement of esthetic dentistry has been accelerated from the development of composite resin and dentin-enamel adhesive since 1980's. The indirect composite resin restorations have more accurate proximal contact point and occlusal form than direct restoration. And the side effect of resin shrinkage is minimal because the amount of composite used in oral cavity is limited in cement space. As a results, marginal leakage, hypersensitivity, secondary caries, and discoloration are significantly diminished. The first generation laboratory composite resin used in indirect resin restoration had been widespread in 1980's and the second generation laboratory composite resins were developed in 1990's. The second generation laboratory composite resins are called Ceramic Polymer. The physical properties of Ceramic Polymer are improved because of high content of inorganic filler, and the esthetics and biocompatibility are better than that of the first generation resin. So the application range using composite resin have been broadened. The purpose of this paper is to introduce Targis & Vectris system that is classified to second generation laboratory composite and to report several cases in which the system was utilized for restoration.

There is a difficulty for many practioner in anterior direct restroation with composit resin. Because its result is various according to patient, a practioner have a fear about that unpromisable result. Moreover in esthetic region, there is difference in satisfaction by patient character. That is one of difficulty in this practice. But if we make a manual for parctice it will be easier. So I will summarize the process and things to note in direct anterior composite resin restoration.

Purpose: This study aimed to assess and compare the marginal fit of ceramic-based hybrid resin restoration (HYB) and zirconia restoration (ZIR) for dental computer-aided design/computer-aided manufacturing systems. Methods: A stainless steel master model was produced. The impression was first made with silicone, and then stone working models were produced. A total of twenty restorations were fabricated with two different materials: ZIR and HYB. The silicone film thickness of the marginal gap was measured using a digital microscope; digital photos were taken at a magnification of ×160, and then analyzed using a measurement software. The values of the result were evaluated with the independent-sample t-test (α=0.05). All statistical analyses were performed with a statistical software. Results: The mean values for the marginal gap was 37.14±2.96 ㎛ for HYB, compared with 40.37±5.26 ㎛ for ZIR. No significant difference was found between ZIR and HYB (p=0.107). Conclusion: As a result, the marginal fit of the restoration fabricated using the hybrid resin was better than that of the restoration fabricated using zirconia. Also, the marginal fit of all groups was below the clinical acceptable range of 120 ㎛. Thus, HYB for dental CAD/CAM system in this study is expected to be suitable for clinical use in dentistry.
