PURPOSE. To assess function by identifying changes in swallowing and masticatory performance in maxillary obturator prosthesis wearers. MATERIALS AND METHODS. Sixty subjects were recruited for the study, of which 20 were obturator wearers, 20 were completely dentulous and 20 had removable partial/complete dentures with similar Eichner's Index. Swallowing ability was evaluated with and without obturator using the "Water Drinking Test"; Masticatory performance was evaluated with the Sieve test; and maximum occlusal force was recorded with the help of a digital bite sensor. The data was analyzed using the Statistical Package for Social Science version 15.0 with a confidence level at 95%. RESULTS. Profile, behavior of drinking and time taken to drink were significantly improved (P<.001) in subjects after wearing obturator. Masticatory performance was not significantly different (P=.252) in obturator wearer when compared with dentulous or removable partial/complete denture wearer, but significantly (P<.001) high inter group difference in maximum occlusal force existed. Correlation between masticatory performance and maximum occlusal force was not significant (P=.124). CONCLUSION. Swallowing ability was significantly improved after wearing obturator but masticatory performance was not significantly different from those having similar occlusal support zone in their dentition.

The authors conducted the tests of the artificial masticatory forces on the everyday life foods divided into six groups of the vegetables, confectionaries, meats, fish, fruits and miscellaneous foods untreated or treated according to the taking of each foods by means of the human skull and electronic strain gauge for the pressure measurement. The results were as follows; 1. The masticatory forces of each foods were different. 2. The masticatory forces of the treated foods were lower than those of the untreated foods. 3. The masticatory forces needed to masticate the everyday life foods were considerably lower than the human maximum bite force. 4. It is reasonable to think the patients wearing well constructed full dentures feel no complications about the masticatory force for the mastication of everyday life foods. 5. The masticatory forces for the confectionaries were greater and more variable than the masticatory forces for the other foods.

PURPOSE. The objective of this study was to evaluate the effect of sociodemographic factors on quality of satisfaction towards denture treatment. MATERIALS AND METHODS. One hundred subjects (filling inclusion criteria) who were wearing a denture for at least two months were enrolled and divided into five groups on the basis of sociodemographic variables (age, gender, literacy level, socio-economic and marital status). Questionnaires consisting of 38 questions (positive and negative attitude towards denture satisfaction) related to patients' perception of clinical outcome in different domains such as mastication, appearance, speech, comfort, health, denture care and social status were scored by the subjects. Questions reflecting positive attitude were scored as 2, 1, or 0 (yes, uncertain and no, respectively) and reversely for the negative questions. Statistical analysis was done by using Statistical Package for Social Sciences (${\alpha}$= .05). RESULTS. Level of denture satisfaction was higher in age subgroup belonging to 45 - 65 years of age in relation to comfort, health and denture care. Female and male showed significant priority for denture treatment because of esthetic and function respectively. Level of satisfaction was statistically significant with literacy level. Upper high income group showed significantly higher level of satisfaction only in case of social status. Married group showed significantly higher satisfaction level only with comfort. CONCLUSION. Patients' sociodemographic variables were influential factors on denture satisfaction.

Implant-supported overdenture is a reliable treatment option for the patients with edentulous mandible when they have difficulty in using complete dentures. Several options have been used for implant-supported overdenture attachments. Among these, bar attachment system has greater retention and better maintainability than others. SFI-Bar$^{(R)}$ is prefabricated and can be adjustable at chairside. Therefore, laboratory procedures such as soldering and welding are unnecessary, which leads to fewer errors and lower costs. A 67-year-old female patient presented, complaining of mobility of lower anterior teeth with old denture. She had been wearing complete denture in the maxilla and removable partial denture in the mandible with severe bone loss. After extracting the teeth, two implants were placed in front of mental foramen, and SFI-Bar$^{(R)}$ was connected. A tube bar was seated to two adapters through large ball joints and fixation screws, connecting each implant. The length of the tube bar was adjusted according to inter-implant distance. Then, a female part was attached to the bar beneath the new denture. This clinical report describes two-implant-supported overdenture using the SFI-Bar$^{(R)}$ system in a mandibular edentulous patient.

치과보철과에는 장기간 총의치를 사용해 온 고령 환자 중에서 발치 후 시간의 경과와 함께 심하게 치조골이 위축된 상태로 환자들이 종종 내원하게 된다. 통상 하악 총의치는 하악 협붕 부위의 1차 지지를 기반으로 한 개구인상법에 의해 제작하는 것이 일반적이다. 하악 총의치의 유지력 및 안정성을 확보하기 위해서는 진단에서부터 의치 주위 조직의 기능 및 의치상의 경계, 교합평면, 악궁의 대합관계, 인공치아의 배열, 저작습관, 그리고 환자에 대한 교육과 장착 후 주의 사항 등을 충분히 고려해두어야 한다. 그러나 치조골 위축이 심하게 발생된 무치악 환자에서 개구인상법을 이용하여 제작한 하악 총의치는 간혹 실제 저작과정에서 유지와 안정에 한계를 보이는 경우가 있기 때문에, 이에 대한 대안으로 폐구인상법을 이용한 총의치 제작 방법을 선호하는 임상가들에 의해 개구인상법과 폐구인상법을 비롯한 다양한 인상채득 방법을 비교한 연구가 보고되기도 하였다. 본 증례에서는 폐구인상법을 토대로 한 기능인상으로 하악 총의치를 제작하여 동일한 환자에서 개구인상법으로 제작한 의치보다 나은 유지력과 안정성을 확인했고, 심하게 치조골이 위축된 상태의 구강조건에서 개구인상법으로 제작한 의치와 폐구인상법으로 제작한 의치의 임상적 결과를 비교한 내용에 대해 보고하고자 한다.

Objectives : The aim of this study is to investigate the possible impact factors on adults' self-reports of dry mouth and to develop strategies to improve oral health education policy. Methods : This study was conducted on a total of 622 self-administered questionnaires adult above 20 and under 65 years of age living in Seoul and Gyeonggi provinces. The final participants consisted of 443 adults without chronic illness, taking medications and wearing dentures. The Hierarchical Multiple Regression model with three stages was used to assess the association for exposure of interest, such as socio-demographics, health-related behavior, mental health and self-reported of dry mouth. Results : The participants reported mean score of dry mouth($6.32{\pm}4.47$), of which 191 were male($6.81{\pm}4.56$) and 252 were female($5.94{\pm}4.37$). Hierarchical Multiple Regression revealed that the score of dry mouth was shown to be significantly higher for the following people: Males, who were employed, unemployed, negative self-perceived general health, perceived stress, and participants who had no experience awareness of distress in two weeks. The explanatory power was 21.9%. The most powerful impact factor regarding to employment was shown to be negatively associated to dry mouth, and self-perceived general health, experiencing awareness of distressful in two weeks was also important factors. Conclusions : Based on these results in order to develop oral health education policy strategies for the prevention and management of dry mouth, there need to be considered for the employee.
