Objectives : The purpose of this research was to investigate the awareness of an adult on implants and the relevant factors which affect the satisfaction of a patient after an implant treatment. Methods : This study was conducted to 407 adult subjects in Seoul and Gyeonggi. A total of 384 data were analyzed except the questionnaires having poor responses or errors. Results : The acquaintance route of implant was TV advertisements, self-knowledge, internet, news, and newspapers. Dentist's ability to practice implant was the most important factor in patient's choice. The responents answered the expected lifespan of an implant was more than 5 years to 10 years. In terms of dental health management behavior on implants, the average response of the highest 4.07 points of 5 Likert scale. Generally women are more concerned with implant than men(p<0.01). The highly educated and elderly patients had tendency to receive more treatment(p<0.0001). Patients were more satisfactory after receiving regular checkups after treatment(p<0.05). The low expenses of implant satisfied the patients(p<0.05). Conclusions : As implant technology advances, the concern of patients on implants also increase. So reduction of cost can make the patients have access to the dentist and the patients' oral health must be improved through continuous dental care.

Dental implants are the first option for replacement of missing teeth. Failure usually involves additional cost and procedures. As a result, the physician should limit the risk factors associated with implant failures. Implant site is one of many factors that can influence the success or failure of dental implants. The association between early implant failure (EIF) and implant site has yet to be documented. This review aims to estimate the impact of insertion site on the percentage of EIFs. An electronic and manual search of studies that reported early failure of dental implants based on collection site. A total of 21 studies were included in the review and examined for the association between EIF and alveolar site. Subgroup analysis, including a comparison between implants inserted in four alveolar ridge regions of both jaws was performed. The early failure rate was higher for maxillary implants (3.14%) compared to mandibular implants (1.96%). Applying a random effect, risk ratio (RR), and confidence interval (CI) of 95% revealed higher failure in the maxilla compared to the mandible (RR 1.41; 95% CI [1.19, 1.67]; P<0.0001; I²=58%). The anterior maxilla is more critical for early implant loss than other alveolar bone sites. Implants in the anterior mandible exhibited the best success rate compared of the sites.

Objectives : The purpose of this study was to examine the subjective awareness and expectations of implant patients. Methods : The subjects in this study were 200 implant patients at three different dental clinics in the region of Busan. Results : Concerning awareness of implant, the patients aged between 41 and 50 were best aware of implant with 2.85(p<0.05). By education, those who received college or higher education were best aware of it with 3.53(p<0.001). By income, those whose income was three million won or more were best aware of it with 2.95(p<0.05). As for expectations for implant, the women expected more from it with 2.89(p<0.01). By age, those aged between 41 and 50 had the biggest expectations with 3.63(p<0.001). By education, the patients whose income ranged between 2 and 2.99 million won had the greatest expectations with 2.91(p<0.05). Education and occupation made no significant differences to that. In regard to correlation among their knowledge, awareness and expectations for implant, there was a positive correlation between their knowledge and awareness(0.439), and their awareness had a negative correlation to their expectations(-0.147). Conclusions : The above-mentioned findings suggested that what patients expect from implant should accurately be grasped when counseling is provided, and that accurate information should be provided to them as well. Their cooperation should be requested during implant treatment, and special post-care programs should be prepared to boost their quality of life after receiving implant treatment. Quality medical services should be offered in proportion to the cost of treatment in order to satisfy their expectations.

Objectives: The purpose of the study is to investigate the knowledge, attitude, and recognition of health insurance coverage in tooth implant among Korean adults. Methods: A self-reported questionnaire was completed by 420 adults over 20 years lod in Seoul and Gyeonggido from October 1 to December 15, 2014. The questionnaire consisted of general characteristics of the subjects, knowledge, attitude, and recognition of health insurance coverage in tooth implant. Results: The mean of knowledge of regular checkup after implant was 3.05 points, and mean of advantage and disadvantage of implant was 3.03 points. The expectation for the implant treatment was 4.18 points and this was the highest score. There was no significant difference between the knowledge and attitude in age and monthly compensation(p>0.05). Only 45.6% of the adults were aware of the health insurance coverage of tooth implant since July, 2014. Health Insurance meeds to be modified in the beneficiaries age(44.6%), and cost(32.7%). The positive aspects of implant care included medical expenses(37.8%), health care beneficiary(29.1%), and oral health promotion(20.9%). Conclusions: Health insurance coverage of tooth implant is very important to enhance the quality of life in the adults because the proper management and implementation of the health insurance in implant will improve the oral health care in life.

PURPOSE. A survey was conducted to assess the impact of a TED-like educational session on participants' willingness to accept dental implant therapy. MATERIALS AND METHODS. Volunteers interested in having information about dental implant therapies were recruited and asked to complete a two-part survey before and after an educational session. The initial survey elicited demographic information, self-perceived knowledge on dental implants and willingness to this kind of treatment. A "TED-style" presentation that provided information about dental implant treatments was conducted before asking the participants to complete a second set of questions assessing the impact of the session. RESULTS. The survey was completed by 104 individuals, 78.8% were women and the mean age was $66.5{\pm}10.8$. Before the educational session, 76.0% of the participants refused dental implants mainly due to lack of knowledge. After the educational session, the rejection of dental implants decreased by almost four folds to 20.2%. CONCLUSION. This study proved that an educational intervention can significantly increase willingness to accept treatment with dental implants in a segment of the population who is interested in having information about dental implant therapy. Furthermore, educational interventions, such as TED-like talks, might be useful to increase popular awareness on dental implant therapy.

The difficult oral healthcare in intellectually disabled patients with poor behavioral control has led to debate over the cost-effectiveness and validity of implant treatment in these patients. The patient in the present report had schizophrenia that had led to poor oral care and severe dental caries in the full mouth. Tooth extraction and a removable prosthesis were planned, but the guardian wanted an implant procedure. Since the guardian showed strong will and cooperation with regard to the patient's oral healthcare, extraction followed by immediate implant placement was performed across two rounds of general anesthesia. Since the outcome appears successful, we present this case report. Immediate implant placement after tooth extraction requires fewer surgeries and rounds of general anesthesia, reduces horizontal bone resorption, and can achieve better esthetic results. Therefore, as long as a certain degree of oral care is possible, this can be a positive option for restoration of a partially edentulous mouth, even in intellectually disabled patients.

Objectives: The goal of this study was to estimate the overall satisfaction level of dental implant patients and further evaluate factors influencing satisfaction. Materials and Methods: Self-administered questionnaires were mailed to patients who received dental implant therapy at Seoul National University Bundang Hospital (Seongnam, Korea) from October 2003 to April 2005. The main portion of the questionnaire was shared to evaluate the level of satisfaction with implant therapy. The questionnaires contained evaluations of influencing factors, which were classified as pain-related, service-related, and complication-related. Results: The responses from 93 patients (41 males, 52 females) with a total of 325 implants were included in the analysis, and the mean score for overall satisfaction level with implant therapy was 8.26. Female patients showed higher visual analogue scale (VAS) scores for both pain during (P=0.000) and after implant surgery (P=0.016). Male patients showed more 'negative' values for the reasonability of treatment cost (P=0.008) and the adequacy of the treatment period (P=0.022). Conclusion: The subjective satisfaction of patients was influenced by various factors, especially complication-related factors.

This study was conducted to improve patients satisfaction by comparing patients expectation prior to the implant therapy to patient satisfaction after the implant therapy. The data of 158 patients with dental implant in Seoul, Gyeonggi-Do and Cheonan city was obtained. The results are as follows : 1. 40.5% of patients placed one implant and 36.1 % of patients answered that the average cost for each implant is from 1,500,000 to 2,000,000won. 23.4% of them answered they decided to have implant because no tooth preparation is required. 2. Overall, the expectation level for implant therapy in general properties, women showed higher level of expectation than men. Especially, 'Implant has a longer life than other denture' showed significant difference between women(4.29) and men(3.87). Expectation by age, 'Implant has similar color and shape' was found the highest in age 20(4.38). Satisfaction by general properties, 'No tooth preparation required' was found the highest in age 20(4.57) and was statistically significant(p<.002). 3. Comparing patients' expectation prior to implant therapy to satisfaction afterward, 'Implant prevents jawbone resorption and keeps facial appearance' showed 3.7 of expectation but satisfaction was found increased to 3.87(p=.020). No tooth preparation required' was found 3.95 in expectation prior to implant therapy but after therapy it was found 4.23 in satisfaction (p<.001). 4. Overall satisfaction in implant therapy was found 4.25, recommendation to other patients was found 4.18 and repurchase was found 4.17.

Since the introduction of non-thermal atmospheric pressure plasma in the field of the dentistry, numerous applications have been investigated. Especially with its advantages over existing vacuum plasma in terms of portability, low cost, and non-thermal damage, it can be directly applied in the oral cavity, giving number of potentials for dental application. First, possible application of non-thermal atmospheric pressure plasma in the field of dentistry is relation to dental caries and periodontal diseases. Teeth and alveolar bones are one of the strongest bony structures in our body, but it cannot be regenerated when they are damaged by dental caries or periodontal disease. Hence many studies to prevent such diseases have been carried out, though no perfect solution has been found yet. With recent studies of modifying surfaces through non-thermal atmospheric pressure application that can prevent attachment of bacteria, or studies on bactericidal effects of non-thermal atmospheric pressure plasma can be applied here to prevent oral pathogen and 'biofilm' attachment to the surface of teeth or directly eliminate the dental caries/periodontal disease causing germs. Secondly, non-thermal atmospheric pressure application will be useful on the surface of dental implant. It is well known that the success of dental implant surgery depends on the process known as 'osseointegration' that result from osteoblast attachment, proliferation and differentiation. As the application of non-thermal atmospheric pressure plasma on the surface of dental implant just before its introduction by the chair-side of dental surgery. Despite its long history, the generation of non-thermal atmospheric pressure plasma has been greatly increased with its application in dentistry.

STATEMENT OF PROBLEM: While patient-centered outcomes are usually not reported, these may represent major aspects of the implant success for the patient. Use of a well-designed patient survey form can be an invaluable asset to the implant practitioners. PURPOSE: The objective of this study was to investigate patient satisfaction after implant therapy by means of a questionnaire. MATERIAL AND METHODS: South Korean patients (n = 100), who visited the dental examination center of Soon Chun Hyang university hospital, were asked to fill out the satisfaction questionnaire regarding aspects of cost, comfort, esthetics, chewing, gingival health, food impaction, phonetic aspect, screw loosening, and general satisfaction. Responses to statements were given on the Likert response scale. Four experimental groups of patients were distinguished with various location ($A_1,\;A_2,\;A_3$), year ($B_1,\;B_2,\;B_3$), number of implant replacements ($C_1,\;C_2,\;C_3$), and treatment cost ($D_1,\;D_2,\;D_3$). The reliability of the response scales was measured by calculation of its internal consistency, expressed as Cronbach's ${\alpha}$. The scales were distinguished by means of factor analysis method. Possible differences in scale scores among the groups were assessed by One-way ANOVA (${\alpha}$= 0.05). RESULTS: Patients responded to most of the statements with high satisfaction. But the mean scale score of statement about cost was low. After the verification of internal consistency and factor analysis, five components, e.g. general satisfaction, comfort, chewing efficiency, esthetics, and phonetic aspect were grouped together. These components could be explained with common meaning and the first factor was named as 'general satisfaction'. Differences in patient satisfaction on the scale with esthetics were present between patients who have been wearing the implant prosthesis less than three years and those more than seven years ($B_1<B_3$). CONCLUSION: The patients were generally satisfied with the outcome of implant treatment. But the patients' major complaint was high cost and while the statistically significant difference was not shown, the satisfaction scale about food impaction and esthetics was low. So the continuing efforts to make improvements about these problems are needed for the implant practitioners.
