Title: Rehabilitation of mandibular partial edentulous patient with remaining unilateral teeth using implant-assisted removable partial denture Author(s): Hyo-gyoung Yi; Kwang-yeob Song; Seung-geun Ahn; Ju-mi Park; Jae-min Seo Abstract: For patients with a few remaining teeth, if an implant supported fixed partial denture is difficult due to the patient’s systemic or local conditions, or due to their economic situation, a removable partial denture may be considered as a treatment option. If a few teeth remain unilaterally to the midline, placement of the implant on the contralateral side and designing an implant-assisted removable partial denture (IARPD) may improve the retention and support of the removable partial denture and protect weak abutment teeth. In this case, a partially edentulous patient with a few remaining teeth located unilaterally on the mandible was treated using a maxillary distal extension removable partial denture and mandibular IARPD after implant placement on the mandibular edentulous area. We achieved an esthetically and functionally satisfying outcome.

Title: Treatment of excessive gingival display using modified lip repositioning technique with esthetic crown lengthening : Case reports Author(s): Gwi-hyeon Min; Sang-joun Yu; Byung-ock Kim; Won-pyo Lee Abstract: Excessive gingival display that can be seen when a person smiles can cause non-esthetic problem. This gummy smile is mainly caused by an altered passive eruption, bony maxillary excess, and excessive maxillary lip mobility. Thus far, an altered passive eruption has been successfully treated using esthetic crown lengthening. Recently, an alternative to orthognathic surgery has been proposed for the treatment of a gummy smile. Studies using a lip repositioning procedure have actively been performed. In this report, we present three cases of treatment for excessive gingival display using the modified lip repositioning technique associated with esthetic crown lengthening.

Title: Comparison of the perception of public posts between students enrolled in dental college and in graduate school of dentistry Author(s): Ja-won Cho; Su-hyun Shim Abstract: This study was designed to investigate the perception of public posts between students enrolled in dental college and in graduate school of dentistry and to propose the new curriculum and public policy to be more appropriate for the future. Study participants were 397 students in dental college and 160 students in graduate school of dentistry. A self-reported questionnaire to ask about socio-demographic characteristics, career plan and the perception of public posts was conducted for 557 students. The data were analyzed using a chi-square test, frequency analysis, and Pearson’s correlation coefficient. There were significant differences in socio-demographic characteristics, major satisfaction, and career plans between the two groups. Although these two groups have different backgrounds, both groups of students were motivated by opportunities to get a specialized job and wanted to contribute to public welfare as healthcare professionals in public posts. Most students (96.2%) agreed that government should set up public posts for dentists. Significantly, students in graduate school of dentistry were more likely to quit their jobs if they had opportunities to fill public posts (48.1%) and most of them (38.5%) ranked administrative positions higher than other types of public posts as a desired job. Additionally, students living in the Korean metropolitan area showed the tendency to work in the Korean metropolitan area after graduation, while those living in other areas wanted to work in areas outside the metropolitan area (P<0.001). Though a more well-designed longitudinal study is needed, this study can be valuable for curriculum development and health policymaking.

Title: Inter-radicular distance between the maxillary second premolar and the first molar Author(s): Seo-rin Jeong; Sun-kyoung Yu; Min-su Kim; Sung-hoon Lim Abstract: The aim of this study was to evaluate the effect of the curvature of mesiobuccal root of the maxillary first molar in the space between the maxillary second premolar and the first molar, which is the preferred site for mini-implant placement. In this study, cone-beam computed tomography (CBCT) data of 85 patients (36 male, 49 female; 14-38 years old) were used to measure the mesiobuccal root length of the maxillary first molar and the distance from the cementoenamel junction (CEJ) to the most curved point of the mesiobuccal root of the maxillary first molar. The interradicular distance between the maxillary second premolar and the first molar, and the buccolingual width of alveolar bone and cortical bone thickness at the plane 4-, 6-, and 8-mm apical to the CEJ were also measured. The length of the mesiobuccal root of the maxillary first molar was 11.2 ± 1.1 mm, and the distance from CEJ to the most curved point was 6.4 ± 0.7 mm, which was about 57.4% of the root length. The interradicular distances were almost same at the 4- and 6-mm planes, but increased significantly between the 6- and 8-mm planes. Although the buccolingual widths of the alveolar bone was increased apically, cortical bone thicknesses were not different among the 4-, 6-, and 8-mm planes. The interradicular distance does not increase between the 4-mm and 6-mm planes from CEJ because of the presence of the curvature of the mesiobuccal root of maxillary first molar.
