A randomized controlled clinical trial on press and block lithium disilicate partial crowns: A 4-year recall.

Purpose: To evaluate clinical performances of two lithium disilicate systems (Initial LiSi press vs Initial LiSi Block, GC Co.) using modified United States Public Health Service (USPHS) evaluation criteria and survival rates after 4 years of clinical service.

Methods: Partial adhesive crowns on natural abutment posterior teeth were made on 60 subjects who were randomly divided into two groups: Group 1: Initial LiSi press and Group 2: Initial LiSi Block.

Comparison of trueness and repeatability of facial prosthesis design using a 3D morphable model approach, traditional computer-aided design methods, and conventional manual sculpting techniques.

Statement Of Problem: Manually sculpting a wax pattern of a facial prosthesis is a time-, skill-, and resource-intensive process. Computer-aided design (CAD) methods have been proposed as a substitute for manual sculpting, but these techniques can still require high technical or artistic abilities. Three-dimensional morphable models (3DMMs) could semi-automate facial prosthesis CAD.

Leading the American Academy of Nursing: A historical review of the Presidents' words and actions on "rationality," inclusivity, and health policy, 1973 to 2023.

Background: Little has been written about the history of the American Academy of Nursing (Academy). An examination of the association's origins, purpose, early goals, and leaders' words and accomplishments can illuminate the organization's role within the profession today.

Purpose: This paper begins the process of documenting the Academy's history.
