RESUMEN
With the recent development of digital dentistry, fully digitalized methods for fabricating dentures, using intraoral scans and computer-aided design/computer-aided manufacturing (CAD-CAM), are getting popular. Digital methods have the advantage of simplifying the fabrication process in the clinic and laboratory, supplementing digital data. This case report shows a fully digital fabrication method for interim removable dentures in a patient with anterior tooth loss in which implant placement is impossible or delayed. Interim removable dentures were fabricated using two methods. One method is printing tooth and base parts separately and combining, and the other method is printing the whole denture at one time and coloring on the base part. Afterward, dentures were delivered and adaptation was evaluated using the triple scan technique. The extracted site was scanned intraorally (first scan) and the interim removable denture was digitally scanned both intraorally (second scan) and, after removal extraorally (Third scan). In both method, denture adaptation was shown favorable. We report this case report as both the patient and the operator were satisfied with a simplified process using a fully digital method in the clinic.
RESUMEN
BACKGROUND: In an effort to use cigarette warning labels as a means for reducing smoking rates, this study examined current cigarette warning messages and newly designed pictorial warning labels. METHODS: From June 15, 2005, to June 22, 2005 we conducted an e-mail survey of 1,200 civilians to examine the effect of cigarette warning labels. For statistical analysis, we used chi-square test with SPSS 11.0 software. RESULTS: Among all the respondents, 78.7% indicated that current cigarette warning labels did not have any effect. However, most of the respondents indicated that pictorial warning labels are effective in raising public awareness (84.6%) or knowledge (81.5%) of the harmful effects of cigarettes. They also responded that pictorial warning labels would help them quit smoking (75.9%) or keep them from buying cigarettes (64.1%). Over 80% of the respondents and over 70% of the smokers responded that they would welcome the use of pictorial warning labels as an anti-smoking measure. CONCLUSION: The results of this study showed that current cigarette warning labels are not effective in curbing smoking rates. Also, the results suggest that current cigarette warning labels need to be improved if they are to be used as an effective anti-smoking measure.
