발치 즉시 임플란트는 치료 기간을 단축할 수 있을 뿐만 아니라 여러 가지 장점으로 인해서 치과임상에서 유용한 임플란트 치료법으로 인식되면서 널리 적용되고 있다. 다양한 이유로 인해서 하악 제1대구치의 발치가 필요한 5명의 환자에게 발치 즉시 임플란트 치료를 진행하여 전체 치료 기간을 단축하면서 만족스러운 결과를 얻었다. 발치 즉시 임플란트는 발치와 내 정확한 위치에 적절한 초기고정을 얻어야 하고 주위 연조직도 개선해야 하는 고난도 치료법이지만 임상적으로 매우 유용한 보철 수복 방법이라고 판단된다.

Purpose This study was performed to evaluate the stability of dual thread implant using resonance frequency analysis in human. Materials and methods Fifty-five patients(32 males and 23 females) with a mean age of 50 years and 1 month who were treated during March, 2005 to July, 2007 in Pusan National University hospital. Totally 145 dual thread Implants were installed and initial stability was measured by Osstell $Mentor^{TM}$. After 3-6 Months, secondary stability was measured at the time of second surgery or before prosthetic treatment. Results At the time of 1st surgery, average ISQ value was $75.12{\pm}12.06$. Only 1 implant was failed during the healing period. Before prosthetic treatment, ISQ values were measured and its mean value was $80.94{\pm}6.12$. Conclusion These results suggest that the increased stability of the implant verifies the clinical relevance of double thread implant.

Background: Reduced bone height is one of the major problems faced in restoring tooth loss with implants. By the use of short implants, it is possible to reduce complicated and invasive treatment such as bone graft, allowing more simple surgery. But short implants are generally considered to have lower success rates than that of standard implants. Purpose: To assess the results of short Straumann implants by a retrospective study of short Straumann implants with TPS(titanium plasma-sprayed) and SLA(sandblasted, large grit, acid etched) surfaces. Materials and methods: 173 implants in 106 patients who received short Straumann implant surgery(${\le}8\;mm$) in the department of oral and maxillofacial surgery, Kyunghee Dental Hospital, from February 1996 to October 2006 were selected and studied. All of the implants were followed up after prosthetic rehabilitation. The average follow-up period was 34 months with 119 months as the longest follow up period. The average follow-up period after prosthetic rehabilitation was 31 months. 64 females(60.4%) and 42 males(39.6%) participated in the research with the age range of 19 to 85(mean age 47). 20 patients(18.9%) were under 40, 85 patients(80.2%) were over 40 and under 70, and only one patient(0.9%) was over 70 years old. Results: 27 implants(15.6%) had TPS surface while 146 implants(84.4%) had SLA surface. 9 implants(5.2%) were 3.3, 108 implans(62.4%) were 4.1mm and 56 implants(32.4%) were 4.8mm in diameter. 167 implants(96.5%) were 8mm and 6 implants(3.5%) were 6mm in length. There were 24 implants(13.9%) on the maxillas and 149 implants(68.8%) on the mandibles. 119 implants(68.8%) were rehabilitated with FPD(fixed partial denture), 47 implants(27.2%) with single crowns and 4 implants(2.3%) with overdentures. Among the fixed partial dentures, 30 of them were splinted with short implants only. After over an year of follow-up period, 139 implants(96.5%) out of 144 implants showed marginal bone loss of less than 1mm. 3 out of 173 implants failed showing 98.27% survival rate. Conclusions: The use of short Straumann implants(${\le}8mm$) can be a simple and reliable treatment method in minimal residual bone height.

Opening special dental office like prosthetic, orthodontics and implant is getting popular from the specialization and ramification on dental service. It shows how changes onpeople's point of view on dental offices as a business and high interesting on aesthetic. The child dental office also specialized from 1990s. It had been divided by not sort of sickness but ages of children. Thus it should support not just basic functions what other dentist of vice does but also comfortable environment to guide children patients' behavior who get afraid easily. However the interior of existing the child dental office was more focused on visual decoration but consideration of space. Thus the space is very superficial and plain, so there is limitation to give suitable environment to children patients. Therefore, from this study, I will research what is the proper space to control children patients' behavior based on well balance of space and decoration designs. Also from the research, I will explain fundamental design ideas on the child dental office space.

PURPOSE. The modified lateral-screw-retained implant prosthesis (LSP) is designed to combine the advantages of screw- and cement-retained implant prostheses. This retrospective study evaluated the mechanical and biological complication rates of implant-supported single crowns (ISSCs) inserted with the modified LSP in the posterior region, and determined how these complication rates are affected by clinical factors. MATERIALS AND METHODS. Mechanical complications (i.e., lateral screw loosening [LSL], abutment screw loosening, lateral screw fracture, and ceramic fracture) and biological complications (i.e., peri-implant mucositis [PM] and peri-implantitis) were identified from the patients' treatment records, clinical photographs, periapical radiographs, panoramic radiographs, and clinical indices. The correlations between complication rates and the following clinical factors were determined: gender, age, position in the jaw, placement location, functional duration, clinical crown-to-implant length ratio, crown height space, and the use of a submerged or nonsubmerged placement procedure. RESULTS. Mechanical and biological complications were present in 25 of 73 ISSCs with the modified LSP. LSL (n=11) and PM (n=11) were the most common complications. The incidence of mechanical complications was significantly related to gender (P=.018). The other clinical factors were not significantly associated with mechanical and biological complication rates. CONCLUSION. Within the limitations of this study, the incidence of mechanical and biological complications in the posterior region was similar for both modified LSP and conventional implant prosthetic systems. In addition, the modified LSP is amenable to maintenance care, which facilitates the prevention and treatment of mechanical and biological complications.

The main objective of this study is to investigate the improvement of the quality of dental health based on the dental service satisfaction factors of the old dental prosthesis patients of more than 60 years of age who use the dental institutes including dental hospital, clinic, and public health center and to identify the interest in the dental prosthesis as changing paint. Across the country through a questionnaire survey of a question and answer type conducted by the trained dental hygienists or dentist's. Major results of the empirical analysis are as follows. 1. looking at variation of the variables of socio-demographic features of the respondents, the group of female, age distribution of 60-65, average monthly income of 0.5-1 million Won, and schooling background of college showed significant difference. And the prosthesis treatment in terms of the purpose of isiting a dental institute, and the dental clinic in terms of the type of visiting dental institute showed a remarkably significant difference. 2. looking at variation of variables of the general features of the respondents, a prosthesis satisfaction service in terms of age showed significant difference: a prosthesis satisfaction service, dental staffs' service and dental facilities' service in terms of average monthly income showed significant difference: the entire conditions except for the dental facilities' service in terms of schooling and general features showed significant difference: and in terms of the purpose of visiting dental institute, it showed no significant difference. In terms of a visiting dental institute, the prosthesis satisfaction service, dental facilities, overall level of satisfaction, result of treatment, word of mouth and revisit showed significant difference. 3. looking at variation of the variables of post-installation prosthesis satisfaction of the respondents, the prosthesis satisfaction service, dentist's dental service, staffs' service, dental facilities' service and revisit in terms of the prosthesis type: and the prosthesis satisfaction service, word of mouth, revisit and overall level of satisfaction from the perspective of serious concern showed significant difference. The prosthesis satisfaction service and dentist's service in terms of the solving the economic burden: and the entire variables in terms of dissatisfaction elements showed a similar level of significant difference 4. in regard to the satisfaction of dental service and the change of the recognition of prosthesis patients, it was revealed that the level of dental prosthesis satisfaction of the respondents was closely related to the dentist's service, staffs' service, and dental facilities' service. Finally, looking at the influence of the dental service on the treatment result, satisfaction, word of mouth, revisit and the overall satisfaction level, it was revealed that they had a great impact on the prosthesis satisfaction service.

PURPOSE. To assess removable prosthetic restoration tolerance according to the patient section of the short form of the Gagging Problem Assessment Questionnaire (GPA-pa SF) and the influence of gender, education level and prosthesis type and denture-related mucosal irritation on the GPA-pa SF scores before treatment and over a period of two months after prosthesis insertion. MATERIALS AND METHODS. 130 participants who required removable prosthesis were surveyed with a standard form that included questions regarding age, gender, education level, dental attendance, and prosthetic restoration type. Participants answered the GPA-pa SF before restoration (T0) and 1 day (T1), 2 days (T2), 15 days (T3), 1 month (T4), and 2 months (T5) after prosthesis insertion. RESULTS. Of the 130 participants, 110 participants completed the prosthetic restoration procedure, but only 93 of these were able to use the prosthesis over the two-month period. The mean GPA-pa SF score obtained at T0 was higher than the scores obtained at the other periods in the total of the sample. Significant difference was present between mean scores obtained at T0-T1 and T2-T3 than scores obtained at other periods (P<.05). Female participants and participants with denture-related mucosal irritation had higher GPA-pa SF scores at all time points analysed. Significant difference was present between mean GPA-pa SF scores obtained at T2-T3 than scores obtained at other periods for females and participants with denture-related mucosal irritation (P<.05). Education level and prosthesis type did not significantly influence the GPA-pa SF score at any time point analysed (P>.05). CONCLUSION. GPA-pa SF scores were higher before the restoration procedure began, and decreased over time with the use of prosthesis. Gender and denture-related mucosal irritation affected the GPA-pa SF scores.
