Considerations on ceramic restoration's polishing method
Shim, Ji Suk ; Ryu, Jae Jun ;
Journal of the Korean Academy of Esthetic Dentistry, volume 24, issue 2, 2015, Pages 78~85

Although the finishing of ceramic restorations affects overall results of prosthetic procedures, the importance of finishing procedures has been underestimated. Finishing procedures have influence on the esthetics, and strength of ceramic restorations, and attrition of opposite tooth. For achieving the appropriate results of these factors, the overall understanding related to the finishing procedures of ceramic restoration is necessary.
Ceramic fabrication for actual color and shape

To harmonize with the remaining natural teeth a dentist and technician make an effort to do. Dental ceramic perfectly reproduce the functionality and esthetic is so moved that will deliver to the patient. However It is not easy to overcome the problem. Actually, it can't have the same spectrum curve between different object. The spectrum curve and reflectance is a unique feature of an object like fingerprints. So it is not that the identification of spectral curves that we usually focuses color. We need to understand the process of matamerism makes something like a combination of color perception. In other word that will tell in our field with ceramic teeth of the patient wish to match the color matching process to simulate the cone in our retinas with the same combination.
Practicality and prospect of full-zirconia restoration
Hwang, Jung-Won ;

Zirconia polycrystalline (Y-TZP) showed better mechanical properties and superior resistance to fracture than other conventional dental ceramics. Zirconia-based ceramics have been successfully introduced into the clinic to fabricate fixed dental prostheses (FDPs), along with a dental computer-aided/computer-aided manufacturing (CAD/CAM) system. It has been clinically available as an alternative to the metal framework for fixed dental prostheses (FDPs). The most frequent clinical complication with zirconia-based FDPs was chipping of the veneering porcelain that was affected by many factors. Another option was full-contour zirconia FDPs using high translucent zirconia. Full-contour zirconia FDPs has many clinical advantages but it caused concern about the wear of antagonist enamel, because the hardness of Y-TZP was over double that of porcelain. However, many articles demonstrates that highly polished zirconia yielded lower antagonist wear compared with porcelains. In this article (1) advantages of full zirconia restorations, (2) clinical applications of zirconia restorations, (3) abutment preparation, (4) surface finish of zirconia restoration and antagonist enamel wear, (5) bond of zirconia with resin-based luting agents, (6) communication in clinical & lab.procedures for full zirconia restorations are reviewed.
Selection of all ceramic crown

The requirements for the successful treatment of all-ceramic restorations are not so different from the ones of conventional restorations. "The provisional restoration followed by an adequate tooth reduction" and "the accurately fitting prostheses with corresponding to final impression" can be the examples of them. Nevertheless, the one which all-ceramic restorations are distinguished from conventional restorations is the additional procedure of so called "bonding". In addition to the application of resin cement between "inner surface of restoration and outer surface of abutment", bonding technology can be also applied to the treatment process of "Post and Core" in particular if the abutments are non-vital teeth. Core build-up for all-ceramic crown is conducted with fiber post and tooth colored composite by considering the properties of the restorations transmitting light. We know well that a vital abutment is easier than a non-vital one to get the targeted goals for clinical success in connection with esthetics and structure. The creation of "Post and Core" with bonding technique is a decisive factor for a long-term success if the abutment is non-vital tooth with dentinal collapse. I would like to share my clinical experience about "post & core build-up and all-ceramic restoration bonding" out of several success strategies of all-ceramic crown with this review article.
Cosmetic Grinding Revisited
Lee, Dong-Hwan ; Chung, Wounho ;
Journal of the Korean Academy of Esthetic Dentistry, volume 24, issue 2, 2015, Pages 134~142

Esthetic dentistry has been developed through the diverse material and technique. Approach and interest in esthetic of anteriors was driven by needs and wants of patients. Alpha and omega of esthetics is determined by patients, as Charles Pincus who is the pioneer of esthetic dentistry described in his article 1967. To meet with wants and needs of patients, dentists suggest possible various treatment options. Cosmetic grinding quoted by Pincus is one of the conservative approaches and provide effective esthetic improvement with minimal invasive concepts. In a high technology era, cosmetic grinding needs to be revisited. Review of some clinical cases shows the value and limitation of it.
