Full mouth rehabilitation of patient with severe dental caries with implant fixed prosthesis fabricated with milling and 3D printing method: A case report / 대한치과보철학회지

Passive fit of prosthesis is an essential property of implant supported prosthesis for long term success and minimization of complications. And the property is determined mostly by fabrication procedure. There were limitations of extensive implant prosthesis because conventional casting method generate contraction error of long span prosthesis. However, Computer-aided design/Computer-aided manufacturing (CAD/CAM) technology of 3D printing and milling metal framework can overcome those limitations. This case is a full mouth rehabilitation using extensive implant fixed prosthesis. Removable interim prosthesis was made for esthetic, functional evaluation and a guide for implant insertion. After the insertion, implant fixed interim prosthesis was delivered. After additional evaluation and adjustment, final prosthesis was designed with CAD, the fabricated with CAM. Milling technique was used for anterior screw type implant superstructure and 3D printing technique was used for the anterior and posterior implant copings. Fit of the final restoration was favorable. The practitioner and patient were both esthetically and functionally satisfied with the final result.

Survey on the consumer preference for the internet health information of the patients' online community members / 대한의료정보학회지

OBJECTIVE: This study was carried out to obtain basic data required to plan and develop consumer-centered internet health information site for Korean population. METHODS: An internet survey was conducted on 5 internet patient community sites between 23 January and 5 February, 2007. A total of 958 surveys were completed and included in the study. Data were analyzed with descriptive analysis, Pearson's correlation analysis, and stepwise logistic regression analysis using SPSS version 12.0. RESULTS: According to our logistic regression analysis, the more internet usage, foreign country residents, members of breast cancer internet community, any workers except sales, and higher level of necessity/usefulness/reliability showed a higher Odds ratio for frequency of internet health information usage. Educational status, frequency of using internet, importance, necessity, usefulness, reliability of internet health information (p<.001), income, and satisfaction of internet health information (p<.05) were statistically significant in the frequency of internet health information usage. CONCLUSION: Above characteristics should be considered for planning to develop consumer-centered internet health information portals.
