Implant prostheses were classified into screw-retained prosthesis and cement-retained prosthesis by their method of retaining, and there is screw and cement retained implant prosthesis (SCRP) which has been made reflecting the strengths of these two. The advantages of the SCRP technique are easy retrievability and passive fit of implant prostheses. However, the occlusal screw holes of implant prostheses can be thought as a disadvantage with respect to esthetics and occlusion. Inappropriately positioned implants also limited the use of the SCRP technique. The present study is reporting about the case where nine implants (US II, OSSTEM, Seoul, Korea) were placed in maxilla and eight in mandible respectively in fully edentulous patients. Then, the cement-retained prosthesis was applied for the part in which the screw hole positioned improperly, and screw-retained prosthesis for properly positioned implants so that the combined screw-cement prosthesis has been produced where the satisfying result has shown in both function and esthetics. Three-year follow-up has been done for the patient.

For treatment of partially edentulous patients, a treatment using implant is widely used. Treatment method using implant are implant fixed prostheses and removable partial dentures, and for patients with severe bone resorption, removable implant overdenture with the effects of aesthetic and reducing cost can be used as treatment options. Specially, prosthesis with milled-bar and attachment has the effect of being splinted between implant fixtures, higher retention and stability than conventional removable partial denture. And it has the effect of improvement of aesthetic through lip support by denture base. In this case, the patient with severe alveolar bone resorption and partial edentulous maxilla and mandible was treated by implant-assisted removable partial denture using Milled-bar and ADD-TOC attachment. The esthetic was improved by removing the clasp because of effects of additional retention by using the attachment, and reducing palatal coverage of implant-assisted removable partial denture. The clinical results were satisfactory on the aspect of aesthetic and masticatory function.

PURPOSE: This study was done to examine the importance of health promotion behavior for infants and toddlers as perceived by mothers of children in early childhood, and graduate students in nursing and to provide information for health promotion in early childhood. METHODS: This study was a cross-sectional survey research study. The participants were 91 mothers of children in early childhood, and 115 graduate students in nursing. RESULTS: The comparisons showed that graduate students in nursing reported higher perception of the importance health promotion behavior for infants and toddlers than did the mothers. In health promotion behavior, the highest score was in the category of safety. CONCLUSION: Providing information by nurses is necessary to promote health promotion behavior for mothers of children in early childhood. Therefore, it is important for healthcare professionals to develop effective programs for these mothers who want to promote good health promotion behavior in their children.

PURPOSE: The present study is aimed to evaluate the combined effect of recombinant human bone morphogenetic protein 2 (rhBMP-2) and recombinant human vascular endothelial growth factor (rhVEGF) coated onto anodized implants on osseointeration. MATERIALS AND METHODS: Six New Zealand white rabbit were used in this study. Each animal received 4 implants that were either coated with rhBMP-2 and rhVEGF (Study group) or anodized implant (Control group) in both tibia. This was performed using a randomized split-mouth design. A total 24 implants were used. The implant stability quotient (ISQ) value using resonance frequency analyser and removal torque (RTQ) measurement were investigated at 2 and 8 weeks. The t-test was used for statistical analysis (alpha=.05). RESULTS: Control and study group showed good osseointegration at 8 weeks. The ISQ and RTQ values of study group were significant compared with the control group at 8 weeks (P<.05). However, No statistical significance was observed at 2 weeks (P>.05). CONCLUSION: It was concluded that rhBMP-2 with rhVEGF coated onto anodized implants can induce better osseointegration at late healing period.

PURPOSE: The effect of accelerated aging on color stability of various dual-cured self-adhesive resin cements were evaluated in this study. MATERIALS AND METHODS: Color stability was examined using three different brands of dual-cured self-adhesive resin cements: G-CEM LinkAce (GC America), MaxCem Elite (Kerr), and PermaCem 2.0 (DMG) with the equivalent color shade. Each resin cement was filled with Teflon mold which has 6 mm diameter and 2 mm thickness. Each specimen was light cured for 20 seconds using light emitting diode (LED) light curing unit. In order to evaluate the effect of accelerated aging on color stability, color parameters (Commission Internationale de l'Eclairage, CIE L*, a*, b*) and color differences (DeltaE*) were measured at three times: immediately, after 24 hours, and after thermocycling. The L*, a*, b* values were analyzed using Friedman test and DeltaE* values on the effect of 24 hours and accelerated aging were analyzed using t-test. These values were compared with the limit value of color difference (DeltaE*=3.7) for dental restoration. One-way ANOVA and Scheff's test (P<0.05) were performed to analyze each DeltaE* values between cements at each test period. RESULT: There was statistically signifi cant difference in comparison of color specifi cation (L*, a*, b*) values after accelerated aging except L* value of G-CEM LinkAce (P<0.05). After 24 hours, color difference (DeltaE*) values were ranged from 2.47 to 3.48 and L* values decreased and b* values increased in all types of cement and MaxCem Elite had high color stability (P<0.05). After thermocycling, color change's tendency of cement was varied and color difference (DeltaE*) values were ranged from 0.82 to 2.87 and G-CEM LinkAce had high color stability (P<0.05). CONCLUSION: Color stability of dual-cured self-adhesive resin cements after accelerated aging was evaluated and statistically significant color changes occurred within clinically acceptable range.

OBJECTIVE: Previous studies have reported that the immune response of hepatitis B vaccine is decreased in preterm or low birth weight babies compared to healthy term babies. To evaluate this notion, we investigated the positive seroconversion rate of hepatitis B antibody after hepatitis B vaccination according to gestational age and birth weight. METHODS: We retrospectively studied medical records about the positive seroconversion rate of a total of 968 infants who were given DNA recombinant hepatitis B vaccine as scheduled at Il Sin Christian Hospital, Busan from January 2002 to Mar 2007. RESULTS: The postive seroconversion failure rate (non-responder or poor-responder) of hepatitis B antibody by gestational age was 15.6% (<28 weeks), 11.4% (>28 weeks, <32 weeks), 5.8% (>32 weeks, <37 weeks), and 1.9% (<37 weeks). The postive seroconversion failure rate by birth weight was 16.7% (< 1,000 g), 15% (>1,000 g, <1,500 g), 5% (>1,500 g, <2,000 g), and 2% (>2,000 g). CONCLUSION: The seropositive rate of hepatitis B antibody after hepatitis B vaccination decreased as the gestational age and the birth weight decreased. And gestational age more than 37 weeks and birth weight above 2,000 g were independently associated with a higher seropositive rate of hepatitis B antibody after hepatitis B vaccination.

PURPOSE: The purpose of this study was to compare the fit of cast gold crowns fabricated from the conventional and the digital impression technique. MATERIALS AND METHODS: Artificial tooth in a master model and abutment teeth in ten patients were restored with cast gold crowns fabricated from the digital and the conventional impression technique. The forty silicone replicas were cut in three sections; each section was evaluated in nine points. The measurement was carried out by using a measuring microscope and I-Soultion. Data from the silicone replica were analyzed and all tests were performed with α-level of 0.05. RESULTS: 1. The average gaps of cast gold crowns fabricated from the digital impression technique were larger than those of the conventional impression technique significantly. 2. In marginal and internal axial gap of cast gold crowns, no statistical differences were found between the two impression techniques. 3. The internal occlusal gaps of cast gold crowns fabricated from the digital impression technique were larger than those of the conventional impression technique significantly. CONCLUSION: Both prostheses presented clinically acceptable results with comparing the fit. The prostheses fabricated from the digital impression technique showed more gaps, in respect of occlusal surface.

Implant overdenture exhibits higher retention, masticatory function, and patient's satisfaction compared to conventional dentures. Particularly, in treatment of severe alveolar bone resorption, implant overdenture can be considered as the first treatment option. The types of attachments used for implant overdenture can be classified into solitary type, which implants are not connected to each other, and bar type in which implants are connected. In the case of solitary type commonly used in clinical practice, parallel relationship is important. When it is not established, there is a higher risk of attachment wear, retention loss, and frequent visits for maintenance. In this case, satisfactory results have been obtained with implant overdentures using milled bar on two unparallel implants placed on the mandible.

Fixed implant prosthesis and removable implant overdenture are the main treatment options for treating edentulous maxilla with implants. If clinicians select one of the treatment options without accurate diagnosis and evaluation, this may lead to unfavorable treatment result and one would not be able to guarantee successful long term prognosis. In this case, 69 year-old female presented with failed fixed implant prosthesis that was treated in private dental clinic. Since the patient did not want additional insertion of implants and considering factors such as oral hygiene maintenance, splinting effect, and esthetics, the patient was treated with removable implant bar type overdenture using pre-existing implants. The clinical results were satisfactory in the aspect of esthetics and masticatory function, oral hygiene maintenance.
