This study was to compare the cumulative survival rate of implant-supported fixed prostheses and to analyze association between risk factors and cumulative survival rate of implant-supported fixed prostheses. In order to assess the clinical status of implant-supported fixed prostheses, individuals who treated in the Department of Prosthodontics, Pusan National University Dental Hospital, between 2000 to 2007 were examined. The results of this study were as follows: 1. Length of service of implant-supported fixed prostheses was
years (mean), 11.7 years (median). 2. Age and sex of patient was found to have no statistically significant influence on longevity of implant-supported fixed prostheses (P>.05). 3. Reason of tooth extraction wax found to have statistically significant influence on implant-supported fixed prostheses (P<.05). The longevity of fixed prostheses was low in tooth extraction case due to periodontal disease (median:9.0 years). 4. Location of implant-supported fixed prostheses was found to have statistically significant influence on longevity of fixed prostheses (P<.05). The longevity of fixed prostheses was low in molar region (median:8.8 years). 5. Number of units in implant-supported fixed prostheses was found to have no statistically significant influence on longevity of fixed prostheses (P>.05). 6. Condition of opposing dentition was found to have no statistically significant influence on longevity of implant-supported fixed prostheses (P>.05). 7. Food impaction (40.5%), porcelain fracture (25.8%), screw loosening (23.6%) were frequent complications.

DOI : 10.14368/jdras.2013.29.4.327
This study aimed to investigate the reinforcing effect of two kinds of glass fiber, Quarts Splint
Mesh and SES MESH
and to evaluate the effect of the thermocycling on the transverse strength of the denture base and on the reinforcing effect of the reinforcements. 20 specimens of the size of
were fabricated for each group; control group, metal mesh reinforcement group, Quarts Splint
Mesh reinforcement group and SES MESH
reinforcement group. To find the difference made by the thermocycling, 10 specimens of each reinforcement group were treated by thermocycling. 3-point bending test was performed to measure the transverse strength of the denture base resin. The specimens reinforced with SES MESH
and Quarts Splint
Mesh showed significantly higher transverse strength than the control group (P<.05), and significantly lower transverse strength than the specimens reinforced with the metal mesh (P<.05). Thermocycled specimens were lower in transverse strength than non-thermocycled specimens in the control group, metal mesh group, Quarts Splint
Mesh group and SES MESH
group, however significant difference (P<.05) was found only in the control group.

It is necessary to consider the median lingual foramen carefully to prevent the bleeding due to the damage of the sublingual artery for implant surgery. This study is to evaluate the frequency, location, diameter and the number of the Mandibular median lingual foramen regarding gender and age in the CBCT. Sixty two images of cone beam computed tomography (CBCT) whose visited the Chonnam National University Dental hospital from Sept. 2010 to Apr. 2011 were evaluated. Frequency, number, location and the diameter of Mandibular median lingual foramen shown in the CBCT image were evaluated. Sixty two patients (100%) had at least one median lingual foramen and fifty six patients (90.32%) had multiple foramens. Forty patients (66.13%) showed the median lingual foramen on the location between Mn. central incisors. The mean vertical position of the genial spine and the median lingual foramen was 24.21 mm and 14.52 mm, respectively. And the relative mean vertical dimension of median lingual foramen was 0.45. The mean diameter of the foramen was 0.93 mm. CBCT demonstrated the frequency, location, diameter and the number of median lingual foramen. It is necessary to take CBCT before implant placement to prevent the bleeding.

When analyzing soft tissue of the profile, Subnasale is often used as an important reference point. But there are few studies on the ideal position of the Subnasale. Therefore, the purpose of this study is to present an objective reference of the esthetic face relating to the change of Subnasale position in Koreans' profile, and also to determine whether there is concordance between professionals and laypersons in their perception of facial attractiveness. The one determined as appropriate profile portion by experts of pictures taken in women in 20s was selected. The photograph was modified changing the Subnasale anteroposteriorly on the plane perpendicular to the true vertical line, while maintaining the nasolabial angle. The photographs were presented to a group of professionals (9 orthodontists) and 126 laypersons, who were asked to assess the facial attractiveness of the photographs on a VAS independently. The conclusion was obtained. 1. The ideal position of the Subnasale is when the ratio of the distance Lateral canthus~Subnasale : Subnasale~Pronasale is 1.769 : 1. 2. The ideal degrees between the true vertical line passing through Nasion and Subnasale is
3. The professionals recognized every change in the ratio, but the laypersons couldn't differentiate between the change from 1.571 : 1 to 1.769 : 1.

Journal of Dental Rehabilitation and Applied Science, volume 29, issue 4, 2013, Pages 359~365
DOI : 10.14368/jdras.2013.29.4.359
The aim of this study was to evaluate the effect of temporary restorative and filling material on bonding strength between lithium disilicate glass-ceramic and dentin. 60 extracted human molars were cross-sectioned at occlusal third and were embedded into self-cure acrylic resin. Then the teeth were randomly divided into four groups of 15 each. Lithium disilicate glass-ceramic is cemented to dentin as follows: after no any application of the provisional materials (Group A), after application of ALIKETM (GC America Inc.)(Group B), after application of Luxatemp
Automix plus (DMG, Germany)(Group C), after application of Fermit
(Ivoclar Vivadent, Leichtenstein)(Group D). After the specimens were stored in distilled water for 24 hours, the shear bond strength of the specimens were measured using UTM (Zwick 1456 41, Zwick, Germany) at a crosshead speed of 1mm/min. The data were analysed by one-way ANOVA and Tukey HSD tests. There were no statistically significant differences of bond strength among the groups. Fracture type was showed mixed type of adhesive and cohesive fracture in most of specimens. Within the limitation of this study, bond strength of adhesive resin cement between lithium disilicate glass-ceramic and dentin was not affected by provisional restorative and filling materials.

The purpose of this study is to evaluate the marginal and internal fit of coping made by CAD/CAM using different scanning methods. Zirconia coping was made by each CAD/CAM system followed by intra-oral scanning, model optical scanning and model contact scanning. It was embedded into Epoxy Resin and was cut by buccal to lingual. AMD (Absolute marginal discrepancy), MG (Marginal gap), GA (Gap of axial), GL (Gap of line angle) and GO (Gap of occlusal) of each sample were measured. The result is as followed; 1. The mean value of AMD in Group 1, Group 2, Group 3 are
. The averages of MG in Group 1, Group 2, Group 3 are
. Statistically there is no difference in AMD and MG among the three Groups (Anova, P>0.05). 2. GA of Group 2 revealed statistically difference compared with Group 1 and Group 3 (Anova, P<0.05). 3. GL and GO of Group 1 showed statistically significant differences compared with Group 2 and Group 3 (Mann-whitney test (P<0.05). Zirconia copings made by 3 ways of scanning methods have no difference with conventional ceramics in AMD and MG which are known as the most important factors.

Journal of Dental Rehabilitation and Applied Science, volume 29, issue 4, 2013, Pages 377~383
DOI : 10.14368/jdras.2013.29.4.377
This study examined the radiopacity of eight contemporary luting cements by direct digital radiography. Five disc-shaped specimens (
) were prepared for each material tested (BisCem, Clearfil SA Luting, Duolink, Maxcem Elite, Multilink Speed, Panavia F 2.0, RelyX Unicem Clicker, V-link). The specimens were radiographed using a Kodak CS 7600 image plate (Carestream Health, Inc., Rochester, NY, USA) and an aluminum step wedge with a range of thicknesses (1.5 to 16.5 mm in 1.5 mm increments) and a 1 mm tooth used as a reference. A dental X-ray machine Kodak 2200 Intraoral X-ray System (Carestream Health, Inc., Rochester, NY, USA), operating at 70 kVp, 4 mA, 0.156 s and a source-to-sample distance of 30 cm, was used. According to international standards, the radiopacity of the specimens was compared with that of an aluminum step wedge using NIH ImageJ software (available at http://rsb.info.nih.gov/ij/).The data was analyzed by ANOVA and a Tukey's post hoc test. Maxcem Elite (5.66) showed the highest radiopacity of all materials, followed in order by Multilink Speed (3.87) and V-link (2.83). The radiopacity of Clearfil SA Luting (1.35), BisCem (1.33), Panavia F 2.0 (1.29) and Duolink (1.10) were between enamel (1.79) and dentin (0.19). RelyX Unicem Clicker (0.71) showed the lowest radiopacity, which was higher than that of dentin. All materials showed a radiopacity above the minimum recommended by the International Organization for Standardization and the American National Standards/American Dental Association with the exception of RelyX Unicem Clicker.

Shin, Soo-Yeon ;
Journal of Dental Rehabilitation and Applied Science, volume 29, issue 4, 2013, Pages 384~390
DOI : 10.14368/jdras.2013.29.4.384
Postinsertion problems tend to be minimized when a sequential insertion procedure is followed. However, problems may occur as the result of one or any combination of comfort, function, esthetics, and phonetic difficulties. Following the insertion of a partial denture, an appointment for review in approximately 7 days should be made for the patient. At the review visit, the patient should be questioned concerning any problems that have been experienced when wearing the denture. A thorough examination should then be carried out of the oral tissues and the denture, in the course of which signs of tissue damage may be observed. A diagnosis is then made of the cause of all the problems revealed in the history and examination procedures. Appropriate treatment should then be applied to resolve these problems.

Journal of Dental Rehabilitation and Applied Science, volume 29, issue 4, 2013, Pages 399~406
DOI : 10.14368/jdras.2013.29.4.399
Reports about the intrusion of a natural tooth bounded by implants are very rare, although some concerns have been discussed on the intrusion of teeth connected to implants. A female aged 56 years received an implant (mandibular right first premolar) and post/core onto root rest (mandibular right second premolar) and was restored by single zirconia crown, respectively. Molars were implant restorations. Four month after loading, second premolar was intruded and prominent gap was shown between opposite tooth. Because nonspecific discomfort was expressed, observation was decided after explanation of prognosis of tooth without treatment. Three month later reversal to original position was detected on the periapical radiographs and fully recovered position with intimate contact was completed 11 more months later. Till now 2 years and 3 month observation is being performed. Through the observation of spontaneous recovery of a natural tooth bounded by implants, the cause of intrusion and a mechanism of spontaneous recovery could be estimated.
Increase of the Width of Peri-implant Keratinized Tissue using Apically Positioned Flap: Case Report
Chee, Young-Deok ; Seon, Hwa-Kyeong ;
Journal of Dental Rehabilitation and Applied Science, volume 29, issue 4, 2013, Pages 407~417
DOI : 10.14368/jdras.2013.29.4.407
The one of peri-implant soft tissue problems seen during the maintenance phase of implant therapy is an inadequate zone of keratinized tissue. Keratinized tissue plays a major role around teeth and dental implants, helping in maintaining and facilitating oral hygiene. A free gingival graft (FGG) is chosen to correct the soft tissue defects and provide optimal peri-implant health in order to increase the long-term prognosis of the implant reconstruction. However, the patient treated with FGG has pain and discomfort on donor site such as palate. It is also technically demanding, time consuming, and the color match of the tissue is often less than ideal. An apically positioned flap (APF) is selected for increasing the keratinized tissue simply while or after the second stage implant surgery. This case report shows successfully increasing the width of peri-implant kenratinized tissue through APF procedure on small site of dental implant instead of FGG.

This case report describes about recurrent herpetic stomatitis mimicking post-root resection complication. A 49 year-old male patient was diagnosed vertical root fracture of the mesiobuccal root of his left maxillary first molar (#26). The mesiobuccal root was resected following root canal treatment of the same tooth. 19 months later, the patient presented with pain on left hard palate after a barbecue party. Intra oral examination revealed a gum boil-like blister at the hard palate corresponding to the apex of the palatal root of #26. On clinical examination, there was bleeding on probing and the periodontal pocket depth was measured less than 5 mm with no tooth mobility. On a periapical radiograph, periodontal ligament space widening was observed. Tracing the sinus tract with gutta percha cone was attempted, however, it was impossible. Extending the field of vision, small multiple round ulcerations were observed at the palate front which caused pain to the patient. Therefore, the pain was considered a non odontogenic and the patient was referred to the department of oral medicine. The patient was diagnosed recurrent herpetic stomatitis and after 3 days of antiviral medication, the pain and ulceration were subsided.

When restoring edentulous patients with lower complete denture, the smaller supportive and retentive area of mandible can lead to poor support and stability, denture dislodgement and pain resulting discomfort. In this situation, implant prosthesis can improve esthetics, stability and occlusal force. Whereas, patients with a upper complete denture can adjust more easier because of palate. Therefore, it is suggested to rehabilitate fully edentulous patients with lower implant-supported, upper complete denture as one of the treatment options. So, we are going to report the case and literature review about how the lower implant prosthesis opposing to upper complete denture affects the bone resorption of maxillary residual ridge.
