With the recent development of digital dentistry, fully digitalized methods for fabricating dentures, using intraoral scans and computer-aided design/computer-aided manufacturing (CAD-CAM), are getting popular. Digital methods have the advantage of simplifying the fabrication process in the clinic and laboratory, supplementing digital data. This case report shows a fully digital fabrication method for interim removable dentures in a patient with anterior tooth loss in which implant placement is impossible or delayed. Interim removable dentures were fabricated using two methods. One method is printing tooth and base parts separately and combining, and the other method is printing the whole denture at one time and coloring on the base part. Afterward, dentures were delivered and adaptation was evaluated using the triple scan technique. The extracted site was scanned intraorally (first scan) and the interim removable denture was digitally scanned both intraorally (second scan) and, after removal extraorally (Third scan). In both method, denture adaptation was shown favorable. We report this case report as both the patient and the operator were satisfied with a simplified process using a fully digital method in the clinic.

The purpose of this research was to find out their perception of the dental hygiene and level of its knowledge by estimating status of senior adults' dental health management. First, questionnaires were distributed to the 256 target senior adults aged more than 60, who were going to school for senior adults located in Ulju Country and the survey was conducted by interview directly. The results were as follows; 1. As for tooth brushing method, scrubbing method was used in male and rolling method was used in female and the survey results statistically revealed that rolling method was the most used in aged from 60 to 70(68.1%) and scrubbing method was the most used in aged more than 70(80.4%)[p < 0.001]. 2. As for reason of visiting dental clinic, female respondents accounting for the highest said they visited dental clinic when they feel a pain in the teeth and as for frequence of dental clinic, male respondents visited dental clinic for a once per a year. there was no difference statistically according to age(47.9%). 3. As for the perception of the necessity of dental prosthetic treatment, there was higher positive response in the female than male, in the lower aged groups than higher aged group[p<0.05]. 4. As for the question of whether to use of denture or not now, the survey results was statistically that the higher aged group and male groups were higher used dentures [p < 0.001]. 5. As for maintenance of denture, female respondents said the highest that they keep it in cold water after cleaning(95.5%), there was no difference statistically according to age and educational background [p < 0.001].

Excessive tooth wear can lead to decrease in occlusal vertical dimension and can cause pathological changes in the oral environment and masticatory system. When recovering occlusal vertical dimension and occlusion, accurate diagnosis and analysis are essential. This clinical case describes a 75-year-old woman with severely worn dentition due to loss of the posterior support. Full mouth rehabilitation with occlusal vertical dimension increment was planned. Clinical and radiographic examinations, occlusal vertical dimension evaluation, and diagnostic wax-up were performed and patient adaptability was evaluated using provisional restorations. As for definitive restoration, considering economic condition of the patient, removable partial denture was fabricated and solitary implants were placed in the mandibular left and right posterior region to increase support and retention of the removable partial denture. During one year of follow-up, functional and esthetic outcomes were observed satisfactory.

Objectives: The purpose of this study was to investigate the influencing factors of removable dentures satisfaction in the elderly. Methods: A self-reported questionnaire was filled out by 256 elderly in Jeollanam-do from September 1, 2013 to June 30, 2014. The questionnaire consisted of general characteristics of the subjects, denture related characteristics systemic health characteristics and dental health behavior. Removable dentures satisfaction was adapted from Ban. The questionnaire for Removable dentures satisfaction included general treatment satisfaction, masticatory function satisfaction, denture retention satisfaction, aesthetic satisfaction measured by Likert 5 scale. Cronbach's alpha was 0.850 in the study. Data were analyzed for a t-test, one-way ANOVA and multiple regression analysis by using SPSS(SPSS 18.0, USA) program. Results: According to subjective and systemic health condition and oral health condition, there was a statistically significant increase in general satisfaction of treatment, masticatory satisfaction of function, denture satisfaction of retention, aesthetic satisfaction. The overall satisfaction for removable denture showed a significant improvement. In the multiple regression analysis, variation of removable denture satisfaction was positively associated with oral health status{good(b=0.736, p=0.000)}, denture treatment services{dental hospital clinic(b=0.327, p=0.023)}, and systemic health status{good(b=0.241, p=0.047)}. Conclusions: Satisfaction of removable dentures may have a positive impact on oral health condition, hospital type, and associated systemic disease. It is necessary to develop incremental care programs for oral health and systemic health and to make public opinion to encourage the program.

This case report describes the treatment of two fully edentulous patients with mini-implant overdentures using different implant systems on narrow mandibular alveolar bone ridge. They were complaining about discomfort and pain wearing mandibular conventional complete dentures caused by insufficient retention. Each patient received four miniimplants in the interforaminal area of the mandible using the non-submerged flapless surgical approach. One-body type implant (Slimline, Dentium, Seoul, Korea) was used for a patient and loaded immediately after surgery. Metal housings of O-ring were attached by direct technique. For the other patient, two-piece type implant (LODI, Zest Anchors, Escondido, CA, USA) was used and impressions were made for attachment connection of the Locator's metal housings after 8 weeks of surgery. Within this case report, mandibular miniimplant overdentures using different implant systems showed improvement of patient satisfaction with favorable peri-implant tissue response 6 months after attachment connection. However, long-term follow-up is needed for further evaluation.

Purpose: This study was aimed to investigate the frequency of different classes of partial edentulism and the most frequently used design components of conventional removable partial dentures. Materials and methods: 63 patients who were treated with removable partial denture in Kyungpook National University hospital for 2003-2006 were selected. A total of 76 removable partial denture frameworks were investigated. Kennedy classification was used to identify the class of partial edentulism. Results: Results indicated that Kennedy class I removable partial dentures were the most frequently constructed. Most patients' cases were designed without modification areas. Conclusion: The most common type of direct retainer were the RPI clasp and RPA clasp in both maxilla and mandible. Lingual bar, linguoplate and anterior posterior palatal straps were the more frequently used mandibular and maxillary major connectors respectively. We did not have any case about Kennedy class IV patients.

As dental implant treatment becomes popular for both partial and complete edentulous patients, old people with complex systemic diseases also tend to prefer implant-assisted-overdenture or implant-supported-fixed prostheses to conventional complete denture. In this case, 77-year-old female who was on medication for hypertension and osteoporosis and paralyzed on right side due to stroke visited for implant-assisted-overdenture on lower jaw. After oral and radiographic examination, root-assisted magnet overdenture on upper jaw and implant-assisted magnet overdenture on lower jaw are planned. Consequently, overdentures using self-adjusting magnetic attachment(SA) system on both jaws resulted in recovering satisfying function and retention, which is enable to insert and remove with only one hand.

Ectodermal dysplasia is a genetic birth defect in which at least abnormally develop two structures derived from the ectoderm. It is usually inherited in autosomal dominant or autosomal recessive pattern. Oral manifestations are oligodontia, anodontia, dysmorphic teeth(conical shape), decreased occlusal vertical dimension and alveolar bone. Extraoral signs may include decreased or absent sweat glands, sparse and fine hair, saddle nose, hearing loss and decreased production of body fluids including saliva. Most affected children require extensive dental treatment to restore their appearance and help the development of a positive self image. The patient's overclosed profile was due to a decreased vertical dimension. The use of overdenture is to preserve erupted teeth, to accomodate the newly constructed occlusal plane, to improve retention and stability of denture and to maintain the remaining alveolar bone. The restoration of vertical dimension improved the child's speech, swallowing, and eating. Growth continue until the age of approximately 18. As child grows, replacement dentures will have to be fabricated primarily to accomodate increasing vertical dimension and changing dentition. Implants may be indicated later if the alveolar bone is adequate. Periodic recall visits are advised, to monitor the dentures during periods of growth and development, and eruption of the permanent teeth.

Implant supported removable partial denture (ISRPD) using the implants enables favorable rehabilitation by complementing biomechanical limitations of the conventional removable partial denture (RPD). However, continuous recall check is necessary for evaluation of the mechanical and biological complications to ensure good long-term prognosis of ISRPD. This clinical report describes the complication and management in patient of Kennedy class I edentulism with ISRPD using healing abutment. The wear and fracture of healing abutment occurred at 36 months after delivery. So, healing abutment was replaced by connecting $Locator^{(R)}$ abutment for altering into the implant retained partial overdenture.

One of the treatment options for edentulous state patients with residual ridge resorption is implant overdenture using milled bar and attachment. It not only provides improved retention and stability but can also reduce the coverage of palatal surface. In addition, when a small number of implants are used, milled bar has the effect of being splinted between implant fixtures, which makes it mechanically advantageous under functions such as mastication. The patient in this case was a maxillary edentulous state patient with a considerable amount of residual alveolar bone resorption after removing the existing failed implants. Three implants were planted on both sides and an implant overdenture was fabricated using milled bar and ADD-TOC attachment.
