PURPOSE. The present study compared the accuracy between digital and conventional implant impressions. MATERIALS AND METHODS. The experimental models were divided into six groups depending on the implant location and the scanning span. Digital impressions were captured using the intraoral optical scanner TRIOS (3Shape, Copenhagen, Denmark). Conventional impressions were taken with the monophase impression material based on addition-cured silicones, Honigum-Mono (DMG, Hamburg, Germany). A high-precision laboratory scanner D900 (3Shape, Copenhagen, Denmark) was used to obtain digital data of resin models and stone casts. Surface tessellation language (STL) datasets from scanner were imported into the analysis software Geomagic Qualify 14 (3D Systems, Rock Hill, SC, USA), and scan body deviations were determined through two-dimensional and three-dimensional analyses. Each scan body was measured five times. The Sidak t test was used to analyze the experimental data. RESULTS. Implant position and scanning distance affected the impression accuracy. For a unilateral arch implant and the mandible models with two implants, no significant difference was observed in the accuracy between the digital and conventional implant impressions on scan bodies; however, the corresponding differences for trans-arch implants and mandible with six implants were extremely significant (P<.001). CONCLUSION. For short-span scanning, the accuracy of digital and conventional implant impressions did not differ significantly. For long-span scanning, the precision of digital impressions was significantly inferior to that of the traditional impressions.

Three dimensional body scan technology is being targeted for utilization in the apparel industry. The purpose of this study was to test reliability of the body scan data targeting from 20 to 24 year old men by comparing 3DM, 3D body-scanning semi-auto measurement extraction method, Scanworx, 3D body-scanning auto measurement extraction method, and traditional anthropometric method. We found significant differences in 9 out of 25 items in upper body measurements using 3DM and 16 out of 25 items using Scanworx. In the range of difference value of scan measures, it showed 1 item in the absolute value of more than 40mm between two measuring methods, 3 items in 20 up to 40mm, and less than 20mm in other items. Overall, in height items, the numerical value of traditional measure was higher and in girth, width, depth items, 3D scan measure was higher. We found out that reliability of 3D measurements taken from whole body scans was different according to scanners, scanning softwares, programs, and subjects.

To determine the parameters to be considered when designing lower-body apparel, we analyzed the lower-body figures of adult women in their early 20s from Shanghai, China, using 3-dimensional whole body scanner. Thirty-nine lower-body-related measurements were used to analyze the figures of 210 Chinese women. Obesity and height of the lower body, length from waist to crotch, shape of abdomen, and leg bone length were analyzed. Factor analysis was performed and the results were classified into three clusters. The first cluster describes the obesity of the lower body, the second denotes small hip measurement, and the third describes slim and long legs. This is the first study to quantify figure analysis of the lower body of Chinese women using 3-dimensional body measurements. The findings of this study will provide concrete information regarding crotch width, crotch length, inseam, outseam, waist slope, etc., for designing trouser patterns for Chinese adult women.

This study creates a method with more scientific patterns for use in designing golfwear slacks patterns that better reflect the unique characteristics of body types for elderly women aged 60 or older. This study investigates (when designing human-engineering golfwear slacks for elderly women) the body types of elderly women and design slacks patterns suitable for golf actions in order to design golfwear slacks that show excellence in function and aesthetics as well as for exercise and everyday wear conditions. The study indicated that "total crotch length" was the design element for most considerations when manufacturing golf slacks. A survey on the production of golf slacks for elderly women aged 60 or older showed that the 6 firms participating have not produced an exclusive product for women 60 years of age or older and have only manufactured an enlarged size up to 85. All 6 firms participating replied "No" two the question "Do you produce in consideration of the body types of women over 60 years of age?" Polyester-polyurethane composites were the most widely used (among golf slacks materials) as spring-autumn applications.
