Objectives: This study aimed to investigate factors affecting treatment satisfaction of patients with dental implants and quality of life. Methods: A questionnaire survey was conducted for adults who underwent dental implant treatment. at dental departments of general hospitals or dental clinics in Seoul and Gyeonggi-do. Data was analyzed to get descriptive statistics of variables, and was under independent t-test, one way ANOVA, and multiple regression analysis. Results: The mean of total satisfaction with implants was $3.73{\pm}0.41$ in the 5-point scale, and that of general satisfaction was $3.97{\pm}0.53$, followed by mean values of psychological satisfaction of $3.68{\pm}0.51$, aesthetic satisfaction of $3.67{\pm}0.49$, and masticatory function of $3.65{\pm}0.53$. Factors that affect implant treatment satisfaction among patients were monthly income (more than 4 million won), hesitation of the procedure (treatment period), regular checkup (yes) and concerns during treatment (work). Factors that affect the quality of life of patients who underwent implant treatments were satisfaction of aesthetic function and overall satisfaction. Conclusions: The above results showed that the higher the aesthetic satisfaction and overall satisfaction with the implant are, the higher the quality of life of patients get. Therefore, it is necessary for dental specialists to perform dental implants well to improve quality of life of patients.

Hemophilia is a congenital hemorrhagic disease in which blood clotting is impaired and hemostatic abnormalities occur when even one of the 13 factors required for blood clotting are deficient. Among the 13 factors, hemophilia A (factor 8), hemophilia B (factor 9), and hemophilia C (factor 10), depending on the deficient coagulation factor. A male patient in his 40s diagnosed with hemophilia A visited the dentist at Eulji University Hospital for problems with alveolar bone absorption and periodontal abscess caused by overall chronic tooth inflammation, and showed overall bone absorption and inflammation at the time of initial diagnosis. No complications or bleeding tendency were observed in the rest of the area except for #35 and #36 due to regular visits for 10 years, overall good oral conditions, and no side effects or complications were observed.

Objectives: The purpose of the study is to investigate the influencing factors of satisfaction and revisiting intention of dental implant patients. Methods: An interview and a self-reported questionnaire were completed by 190 patients in 10 dental clinics in Daegu, Gyeongbuk, and Gyeongnam from September 17 to October 31, 2015. The questionnaire consisted of the general characteristics of the subjects and satisfaction of implant. The instrument for implant interview was adapted form Pjetursson et al. by Likert 5 points scale. Cronbach's ${\alpha}$ in the study was 0.768. Data were analyzed by SPSS/AMOS version 21.0 program. Results: Cost satisfaction had direct effect on satisfaction of expectation and indirect effect on revisiting intent. Mastication satisfaction had the direct effect on satisfaction of expectation and revisiting intent, and indirect effect on revisiting intent. Satisfaction of aesthetic function had the direct effect on satisfaction of expectation, and the indirect effect on revisiting intent. Conclusions: The determining factors of successful dental implant included expenses, mastication function, and aesthetic satisfaction. The competent dental implant teamwork and appropriate expenses can satisfy the implant patients.

Objectives : This study aims to provide the basic data for the maintenance and management of healthy implants through finding out the educational experience of toothbrushing and the oral hygiene management for the implant patients and to determine the maintenance measure. Methods : From April 1 to october 1, 2012, 250 patients in the dental clinic in Daejeon completed the self-reported questionnaire. Results : As for the educational experience of toothbrushing, 66.4 percent received the training for toothbrushing and 33.6 percent had not received the training for toothbrushing. Those who brushed three times a day accounted for 74.1 percent. Those who received the training for toothbrushing comprised 56.0 percent and took regular check up of every 6 months. Approximately 50.0% received regular scaling service every 6 months. Periodical medical check up comprised 55.6% among those who received toothbrushing education. Approximately 63.9% thought that periodical medical check up is the most important to maintain oral health. Conclusions : There were important factors for oral health. They were tooth-brushing, the utilization of various oral hygienic products, and the awareness of importance of oral hygiene management. The customized education program for the general public should be implemented as regular as possible.

Extraction of highly injured teeth in the maxillary anterior teeth and implants restoration is almost good choice, lastly, you tried to save highly injured teeth is a good choice if you have a trust relationship between the dentist and the patient. If the dentist and the patient work together to achieve long-term maintenance, they will create a thicker trust relationship.

Statement of problem: Implant supported overdenture is accepted widely as a way to restore edentulous ridge providing better retention and support of dentures. Various types of attachment for overdenture have been developed. Purpose: The purpose of this study was to investigate the influence of attachment type in implant overdentures on the biomechanical stress distribution in the surrounding bone, prosthesis and interface between implant and bone. Material and methods: Finite element analysis method was used. Average CT image of mandibular body(Digital $Korea^{(R)}$, KISTI, Korea) was used to produce a mandibular model. Overdentures were placed instead of mandibular teeth and 2mm of mucosa was inserted between the overdenture and mandible. Two implants($USII^{(R)}$, Osstem, Korea) were placed at both cuspid area and 4 types of overdenture were fabricated ; ball and socket, Locator, magnet and bar type. Load was applied on the from second premolar to second molar tooth area. 6 times of finite element analyses were performed according to the direction of the force $90^{\circ}$, $45^{\circ}$, $0^{\circ}$ and unilateral or bilateral force applied. The stress at interface between implants and bone, and prosthesis and the bone around implants ware compared using von Mises stress. The results were explained with color coded graphs based on the equivalent stress to distinguish the force distribution pattern and the site of maximum stress concentration. Results: Unilateral loading showed that connection area between implant fixture and bar generated maximum stress in bar type overdentures. Bar type produced 100 Mpa which means the most among 4 types of attachments. Bilateral loading, however, showed that bar type was more stable than other implants(magnet, ball and socket). 26 Mpa of bar type was about a half of other types on overdenture under $90^{\circ}$ bilateral loading. Conclusions: In any directions of stress, bar type was proved to be the most vulnerable type in both implants and overdentures. Interface stress did not show any significant difference in stress distribution pattern.

Esthetic factors are very important in the success of maxillary anterior implant restoration. However, achieving esthetic results is difficult, especially in cases where periodontitis has resulted in severe alveolar bone loss. In the case of maxillary anterior teeth, the alveolar ridge resorption that begins immediately after tooth extraction interferes with the esthetic implant restoration. Therefore immediate implant placement can be performed to minimize the alveolar ridge resorption. However, in severe bone loss cases, immediate implant placement could result in esthetic failure, and this result might cause irreparable problems. We can also perform alveolar ridge preservation and then place implants later. On JCP published in 2019, there is the consensus of European academy of periodontology on the extraction socket management and the timing of implant placement. This consensus states that alveolar ridge preservation should be considered when there is severe labial bone loss in an esthetically important area such as maxillary anterior region. On performing the alveolar ridge preservation, we cannot obtain the primary wound closure, so secondary wound healing is induced with open membrane technique or soft tissue grafting should be performed for primary wound closure. However, the secondary wound healing can have a negative impact on bone regeneration, and soft tissue grafting such as FGG or CT graft can be burdensome for both patients and dentists. On the other hand, by using the granulation tissue in the extraction socket, primary closure can be achieved without soft tissue grafting. Also some studies have shown that granulation tissue in periodontal defects contains stem cells that may help in tissue regeneration. Based on this, implant restorations were performed on maxillary anterior teeth with severe alveolar bone loss by alveolar ridge preservation using granulation tissue. In spite of the severe bone defect of the extraction socket, relatively esthetic results could be obtained in implant restorations.
