  • 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.

  • 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 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.

  • The present randomized controlled trial aimed to evaluate changes in occlusion of indirect restorations before and after attachment using resin cement according to universal adhesives. This study included patients who underwent indirect restoration treatment at the Yonsei University Dental Hospital between April and October 2016. Universal adhesives requiring light curing and those not requiring light curing were used in this study. Changes in occlusion before and after adhesion of the indirect restoration were evaluated using articulating paper and shimstock as well as through the discomfort felt by the patients. To analyze the differences between the universal adhesive, Fisher's exact tests were performed using SPSS ver. 22.0 software. Of the 39 cases of indirect restoration, 29 were included in the study. A change in occlusion after adhesion of the indirect restoration was observed in only one case of universal adhesive that required light curing. The patient felt that the occlusion increased after the attachment of the restoration, and it was observed that the occlusion point was different from that before attachment. However, the results of the analysis were not statistically significant. Based on the findings, the universal adhesives did not affect the occlusion before and after indirect adhesion restoration using RelyX Ultimate.

  • Recently, ceramic materials have become a popular choice for dentists performing esthetic indirect restorations. The longevity and success of ceramic dental restorations depends on the adhesive procedures of resin cements. However, dental ceramics can be classified in various ways, depending on the compositions. Also, the applications for resin cement require multiple clinical steps. Therefore, understanding the different ceramic substrates involved in each procedure, as well as the proper adhesive steps for the resin cements is important to us for long-term clinical success.

  • From the restorative perspective, various methods are available to prevent the progression of non-carious cervical lesions. Direct, semi-direct, and indirect composite resin techniques and indirect ceramic restorations are commonly recommended. In this context, semi-direct and indirect restoration approaches are increasingly favored, particularly as digital dentistry becomes more prevalent. To illustrate this, we present a case report demonstrating the efficacy of hybrid ceramic fragments fabricated using computer-aided design (CAD)/computer-aided manufacturing (CAM) technology and cemented with resin cement in treating non-carious cervical lesions over a 48-month follow-up period. A 24-year-old male patient sought treatment for aesthetic concerns and dentin hypersensitivity in the cervical region of the lower premolar teeth. Clinical examination confirmed the presence of two non-carious cervical lesions in the buccal region of teeth #44 and #45. The treatment plan involved indirect restoration using CAD/CAM-fabricated hybrid ceramic fragments as a restorative material. After 48 months, the hybrid ceramic material exhibited excellent adaptation and durability provided by the CAD/CAM system. This case underscores the effectiveness of hybrid ceramic fragments in restoring non-carious cervical lesions, highlighting their long-term stability and clinical success.

  • Esthetic restoration techniques can be categorized into "Direct techniques" consist only of intraoral procedures and "Indirect techniques" include intraoral as well as extraoral laboratory steps. Those made extraorally exhibit generally enhanced esthetic potential and anatomy and better hardness and wear resistance, indirect esthetic restorations numerously applied in contemporary dentistry. Indirect restorative materials can be divided into two categories; composite resin-based materials and ceramic-based materials. These materials shows various were resistance, modulus of elasticity, repair postenital, chemical stability, and different laboratory procedures. In this session, benefit of indirect techinques, case selection of this kind of restorations, and material characteristics and fabrication produre of those materials will ber reviewed; Targis, Sculpture, Belleglass, and Post-curing of restorative composite resins in resin-based materials; Dicor, Empress, Cerec, Celay, and conventional firing porcelain in ceramic based materials.
