PURPOSE The purpose of this study was to compare the accuracy of the implant master cast according to the type (pick-up, transfer) and the length (long, short) of the impression copings. MATERIALS AND METHODS The metal master cast was fabricated with three internal connection type implant analogs (Osstem GS III analog), embedded parallel and with 10° of mesial angulation to the center analog....

STATEMENT OF PROBLEM Most processed resin denture bases do not fit the cast accurately because of polymerization changes in the resin. The fit is more noticeable in the palate between the denture base and the cast. Therefore, development of a polymerization system that will improve the fit of a denture base to the cast is lack of worth considering to improve the fit and retention of the denture...

MATERIALS AND METHODS: Using open-source CAD modeling software, we developed a customizable prosthetic eye model. The eye can be customized within the following parameters: shape, height, length, width, thickness, concavity, iris diameter, and pupil diameter. The customization process is user friendly, requiring numeric inputs or parametric adjustments. The final model is exported and processed...

This study was conducted to evaluate the predoctoral removable partial denture (RPD) curricula in Turkish dental schools in regards to materials, techniques, and approaches. A questionnaire consisting of eighteen multiple-choice questions was sent by e-mail to the senior members of the prosthodontic departments of seventeen long-established dental schools in Turkey. The response rate was 100 pe...

When Part-of-Speech annotated data is scarce, e.g. for under-resourced languages, one can turn to cross-lingual transfer and crawled dictionaries to collect partially supervised data. We cast this problem in the framework of ambiguous learning and show how to learn an accurate history-based model. Experiments on ten languages show significant improvements over prior state of the art performance.

Statement of the Problem Precision of the impression taken from implant positions significantly determines accurate fit of implant-supported prostheses. An imprecise impression may produce prosthesis misfit. Purpose This study aimed to evaluate the accuracy of four impression-making techniques for angulated implants by stereomicroscope through measuring the vertical marginal gaps between the ...

Cluster Accuracy: agreement with the functional categories Each entry shows the adjusted Rand index of the corresponding algorithm with the functional categories. The maximum adjusted Rand index of each row is shown in bold. The algorithms (rows) are sorted in descending order of the maximum adjusted Rand in each row. DIANA and single-link produce the least accurate clusters. *CAST did not conv...
