Results : Among the study respondents, 39.5% workers and 47.7% Korean adults answered their subjective oral health is not good, but there was no statistically significant difference between them(p< $0.001^{***}$). 39.9% workers and 2 0.6% Korean adults were smokers, and they showed a statistically significance in the ages and genders (p< $0.001^{***}$). 91.2 %workers and 49.8% Korean adults brushed their teeth before going to bed, and they showed a statistically significance in the ages and genders(p< $0.001^{***}$).

The oldsters with edentulous period of over 7years aged in the 70s showed 26.1 % and 56.0% on oldsters aged in the 80s. This shows that as the age increases the edentulous period lengthens. (P<0.05) The length of time of using the denture shows. llyears or over on women 41.9%, less than 6years on men 71.4% as the highest rate. 11 years or over on towns/subcounty show 57.5%, small and medium cities more than 1 year 63.6%, less than six years also 63.6% and Kwangyuk city 47.6%. 2. The complacency on medical treatment of dentures was highest in Kwangyuk city of 61.3%, compared to towns/subcounty of 50.8% and small and medium cities of 33.3%. (P<0.05) 3.

Mandible defects could be caused by congenital malformations, trauma, osteomyelitis, tumor resection. If large areas are included for reconstruction, those are primarily due to tumor resection defects. The large jaw defect results in a problem about mastication, swallowing, occlusion and phonetics, and poor esthetics causes a lot of inconvenience in daily life. It is almost impossible to be a part underwent mandibular resection completely reproduced, should be rebuilt artificially. This case is of a patient who was diagnosed with squamous cell carcinoma pT1N0M0, stage I in February 2004 and received surgery (combined mandibulectomy and neck dissection operation (COMMANDO) in oromaxillofacial surgery) in March 2004, by implant assisted removable partial denture. We could obtain good retention and stability through sufficient coverage and implant holding. Follow up period was about four years. Mandibular left third molar regions have been observed to have resorption of surrounding bone, and periodic check-ups are necessary conditions.
