Kim, Soo-Yeon ; Park, Se-Hee ; Kim, Jin-Woo ; Cho, Kyung-Mo ;
Journal of Dental Rehabilitation and Applied Science, volume 31, issue 1, 2015, Pages 1~9
DOI : 10.14368/jdras.2015.31.1.1
Purpose: The purpose of this study was to evaluate the mechanical properties of several dual-cure cements by different curing modes. Materials and Methods: One resin-modified glass ionomer cement (FujiCEM 2), two conventional dual-cure resin cements (RelyX ARC, Multilink N), and two dual-cure self-adhesive resin cements (RelyX U200, G-CEM LinkAce) were used. To evaluate the influence of the curing methods, each cements divided into four conditions (n

DOI : 10.14368/jdras.2015.31.1.10
Purpose: The aim of the present study was to evaluate the long-term survival of implants retrospectively and determine the risk factors associated with implant failure. Materials and Methods: Of all implants that were placed at the Department of Periodontology of the Dental Hospital of Gangneung-Wonju National University from January 1998 to December 2012, 2265 implants that were followed up until June 2013 were included in this study. Data were collected from clinical and radiographic examinations from previous visits. The information gathered included gender, age, smoking status, implant diameter, implant length, surface of implant, location of implant within the dental arch, surgical techniques and existence of complications. Results: The survival rate before loading was 98.9%. The cumulative survival rate after 5 years of loading was 97.2%, and after 15 years of loading was 95.2%. In a simple logistic regression analysis, gender (P
Spectrophotometric analysis of feldspathic porcelain with silver ion

DOI : 10.14368/jdras.2015.31.1.20
Purpose: This study was evaluated the shade of feldspathic porcelain with various concentration of silver ion. Materials and Methods: The control group was conventional feldspathic porcelain with no silver ion, the experimental groups were the feldpathic porcelain with 5%, 10%, 20%, 30% silver ion. The number of specimens on the each group was 5. Commission Internationale de I`Eclairage (CIE)
parameters were recorded twice for each specimen with a spectrophotometer (Model CM-2600d, Minolta, Japan). One-way Anova was used for statistical analysis. Results: L value was similar. a value was increasing and b value was decreasing with silver ion statistically significantly.
was increasing according to silver ion significantly. Conclusion: The shade of feldspahtic porcelain was influenced by silver ion. Ag ion under 10% concentration is acceptable clinically.
Validity experiment of dipping method in the manufacture of metal-ceramic substructure
Lee, Wan-Sun ; Im, Su-Yeon ; Kim, Wook-Tae ;
Journal of Dental Rehabilitation and Applied Science, volume 31, issue 1, 2015, Pages 26~32
DOI : 10.14368/jdras.2015.31.1.26
Purpose: The main purpose of this study is to suggest application plan of dipping method by comparing & analysing the difference between addition method and dipping method in the manufacture of metal-ceramic substructure of maxillary central incisor (#1), followed by assessing the work efficiency. Materials and Methods: Master die and hard plaster-copied one were produced and then a total of 20 copies, 10 copies for each through addition method and dipping method, were manufactured and experimented. Copings were fixed on the abutment model and invested in epoxy mounting cup. Samples were cut in labial and lingual direction, using cutter and then rubbed on sandpaper, whose 4 points were measured by using digital microscope. Results: The comparison of mean values by using t-test, parametric statistical method, shows overall significant difference (P < 0.05). Conclusion: The result of this study can be suggested as an application plan, since there is no significant difference between addition method and dipping method in the manufacture of metal-ceramic substructure.
Evaluation of marginal bone loss around platform-switched implants by digital subtraction radiography
Kim, Chi-Yoon ; Kim, Sung-Sook ; In, Hee-Sun ; Kim, Yu-Lee ;
Journal of Dental Rehabilitation and Applied Science, volume 31, issue 1, 2015, Pages 33~44
DOI : 10.14368/jdras.2015.31.1.33
Purpose: This study is to evaluate the clinical significance of the platform switching concept by comparing the marginal bone loss around platform-matched and platform-switched implants. Materials and Methods: Date of implant placement, diameter, length, implant-abutment connection type and absence of splinting prosthesis were investigated on patients who performed treatment with implant placement at Wonkwang University Dental Hospital Implant Center. To measure the marginal bone loss around implants, periapical radiographs of patient were used when implant was placed and when visited the center most recently by using the program, Emago advanced v5.6. Results: As a result of observing on 150 implants of 82 patients for 6 - 63 months, platform-matched implants showed

Journal of Dental Rehabilitation and Applied Science, volume 31, issue 1, 2015, Pages 45~49
DOI : 10.14368/jdras.2015.31.1.45
In this clinical report, a simple and convenient conversion of a fractured metal-ceramic surveyed crown into a complete contour zirconia surveyed crown by using computer-aided design and computer-aided manufacturing technology for an existing partial removable dental prosthesis is described. The duplication of the original contours, morphology, and the rest seat of the existing metal-ceramic surveyed crown, into a complete contour zirconia surveyed crown under anticancer treatments were reported.
Maxillary anterior fixed implant prosthesis using customized nonprecious metal casting abutment: a case report
Lee, Jae-In ;

DOI : 10.14368/jdras.2015.31.1.50
It is hard to restore and manage anterior teeth esthetically and functionally; because of peri-implantitis, not only hard and soft tissue problem such as alveolar bone resorption and interdental papilla loss but also esthetic problem caused by metal abutment exposure can occur. This case presents patients using customized abutment made of Co-Cr alloy that can be made by conventional casting and compensate the shortcomings of prefabricated titanium abutments, and cement-retained prosthesis.

Screw loosening and screw fracture of abutment is one of most frequent mechanical complications in implant restoration. Fractured fragments in implant restoration like abutment and screw should be completely removed and the procedure needs minimal damage to the fixture of implant. In some cases, it could fail to remove fractured fragments and cause a lot of damage to the fixture of implant. These situations could render implant unusable at the worst. This article describes three different situations and simple techniques for successful removal of fractured fragments without damage of implants. The procedures used are described in this clinical report.

Computer-guided surgery utilizing computed tomography is advantageous in placing implants precisely and conveniently. The purpose of the cases was to report a newly developed CT-based guide fabrication program and subtractive manufacturing using resin block. The guided surgery with the program and subtractive manufacturing allows not only precise translation of the treatment plan, but also offers additional significant benefits.
