  • Recently, the size of tiles used for bathroom walls in apartment houses is gradually increasing in size. The problem is that when these large-sized tiles are attached by the sticking method, due to the nature of the method, there is a concern about the stability of the attachment to the part (pupil) where the tile and the adhesive are not attached. The problem is serious as it leads to lawsuits in the outbreak court. In addition, it is urgent to verify the adhesion stability of the sticking method because secondary damage occurs due to a safety accident caused by the falling of the tile. Ministry of Land, Infrastructure and Transport [Investigation of defects in apartment houses, calculation of repair cost and defect determination criteria] ① The tile adhesion strength is 0.39N/mm2 or more and ② It is specified to fill 80% or more of the base area of the tile backside, but this is currently trendy. It is considered that large-sized tiles need to be verified from multiple angles, and as part of that, we intend to verify the adhesion stability according to the area to be attached to large-sized tiles.

  • We demonstrated stability-enhanced liquid crystal (LC) displays using pixel-isolated LC mode in which LC molecules are isolated in pixel by horizontal polymer layer and vertical polymer wall. The device shows good electro-optic properties against external point or bending pressure due to the polymer structures. The polymer wall acts as supporting structure from mechanical pressure and prevents the cell gap from bending. Moreover, the polymer layer acts as an adhesive to ensure a tight attachment of the two substrates. We present herein various methods for producing polymer structures by using an anisotropic phase separation from LC and polymer composites or patterned micro-structures for stable flexible liquid crystal displays.

  • This study assessed behavioral characteristics of 73 normal neonates in Daegu area using the NBAS. Being one of few studies on this topic, the study is to document and to accumulate data on the neonatal behaviors of Korean babies. Overall scores were at moderate levels in 6 behavioral clusters including Habituation, Social Interactive, Motor System, State Organization, and State Regulation. Autonomic Stability showed relative stableness. Scores of Orientation were higher in neonates of working mothers and rural mothers. Neonates of mothers with no abortion history have higher scores in Motor System and State Organization. Score of State Organization was higher in neonates of mothers with no habitual use of amenity during their pregnancy. Scores of Habituation and State Organization, as well as scores of Motor System with State Organization, State Regulation and Autonomic Stability were positively correlated. Scores of Habituation and State Organization indicate that babies are agreeable and even tameable that is advantageous for attachment to caregiver.

  • When losing many of the remaining teeth, the relation among them can be put into dynamically unfavorable situation. In the case that the patient without any incompatibilityto the denture, overdenture can be considered. Moreover, we can overcome the dynamical disadvantage, and improve the support, stability, and retention of the partial denture by using implant at the edentulous area. In this case, patient with crossed occlusion between few remaining teeth was treated with maxillary and mandibular partial denture. Single implant fixture was placed at the edentulous space, opposing to the maxillary teeth occluded, and $Locator^{(R)}$ attachment was connected. The patient's esthetic satisfaction was improved by ideally adjusting the tilted occlusal plane. Since the patient was satisfied both esthetically and functionally, and maintained stable during the clinical observation for 6 months after the treatment, we would like to report about it.

  • 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.

  • In edentulous mandible, implant supported overdenture was considered as a first treatment option. Konus type attachment supplies rigid support and cross arch stabilization so that more favorable force transmission and distribution can be attained. In the dentistry, computer aided design-computer aided manufacturing (CAD-CAM) system makes it possible to fabricate restorations with high precision and effectiveness. Recently, Palladium-silver (Pd-Ag) alloy which is millable has been developed. This article presents that application of CAD-CAM Konus type attachment can be provide satisfactory stability and function on four-implant supported mandibular overdenture.

  • Overdenture using dental implants could improve the problems of conventional complete denture function which are pain during mastication, insufficient retention and stability. Locator attachment used widely for implant-retained overdenture has advantages that it needs the smallest vertical space and also its nylon male cap allows personalized retention for each case. However its retention force decreases rapidly with function rather than the bar and ball attachment. So, implant fixture should be positioned as parallel as possible.

  • The retention of complete dentures in patients with Parkinson's disease is often poor due to their constant dislodgement by involuntary movements of the tongue and lips. Furthermore, insertion of the overdenture is expected to be difficult due to their limited voluntary movements. This case is about the bimaxillary overdenture restoration where its retention and stability are improved, using magnetic attachment of remained roots of maxilla and two implant $Locator^{(R)}$ attachments of mandible in patients with Parkinson's disease. This report describes the fabrication of this functionally improved prosthesis.

  • Unlike class I patients, skeletal class II patients have unstable occlusion thus leading to instability of mandibular complete denture. Therefore, mandibular implant overdenture has been the standard of care due to its advantages in stability and retention. The types of attachments can be divided into two categories: solitary and bar type. The indications vary between two categories. In this clinical report, digital technology was utilized from the implant planning to the choice of appropriate attachment. Implants were placed at the desired location as previously planned in terms of angle and depth. Maxillary removable partial denture and mandibular implant overdenture are expected to have fair prognosis.
