Since it was first introduced into the dental world, computer-aided design/computer-aided manufacturing (CAD/CAM) technology has improved dramatically in regards to both data acquisition and fabrication abilities. CAD/CAM is capable of providing well-fitting intra- and extraoral prostheses when sound guidelines are followed. As CAD/CAM technology encompasses both surgical and prosthetic dental ...

This paper describes a project to develop international collaborative CAD/CAM at the Centre for Advanced Manufacturing Research (CAMR), University of South Australia, Australia. The strategy of using the current computer and communication technologies to provide a computer supported cooperative working (CSCW) environment for the national and international CAD/CAM link from collaborative design ...

A CAD/CAM system for manufacturing custom seating inserts was evaluated within a moderately to severely disabled population. Using the Otto Bock Shape System, 25 CAD/CAM seats were manufactured at a remote facility and compared to 9 seats manufactured using hard-sculpting techniques. Clinician and client questionnaires were completed for each seat to assess satisfaction, fitting/manufacturing t...

For the better part of the past 20 years, dentistry has seen the development of many new all-ceramic materials and restorative techniques fueled by the desire to capture the ever elusive esthetic perfection. This has resulted in the fusion of the latest in material science and the pen ultimate in computer-assisted design/computer-assisted manufacturing (CAD/CAM) technology. This case report des...

Introduction: Marginal fit is a key factor for long term clinical success through any dental restorations. Poor marginal adaptation causes cement dissolution. This can lead to dental caries, gingival irritation, periodontal diseases, and finally treatment failure. The aim of this study was measurement and comparison of marginal gap quantities in metal ceramic and all ceramic dental restorations...

Automatic generation of manufacturing information from design has been the research focus in advanced CAD/CAM applications, i.e. feature-based applications for design, process planning and other automated manufacturing applications. However, our current development mode has seriously troubled research in these application fields. For example, with our current development mode, the functionality...

This report examines the current clinical uses of CAD/CAM in prosthetics and orthotics. We conducted interviews to contrast patterns of CAD/CAM use in different private practice settings, at two different teaching institutions, and within two large Prosthetic and Orthotic delivery systems. Investigation into these patterns of use has revealed several lessons. First, there currently exist severa...

OBJECTIVES This study evaluated color differences (ΔEs) and translucency parameter changes (ΔTPs) of various computer-aided design/computer-aided manufacturing (CAD/CAM) blocks after immersion in coffee. MATERIALS AND METHODS Eight CAD/CAM blocks and four restorative composite resins were evaluated. The CIE L*a*b* values of 2.0 mm thick disk-shaped specimens were measured using the spectropho...

background: the aim of this study was to determine the microtensile bond strength (μtbs) of ceramic and composite computer aided design‑computer aided manufacturing (cad‑cam) blocks bonded to dentin using different adhesive strategies. materials and methods: in this in vitro study, 30 crowns of sound freshly extracted human molars were sectioned horizontally 3 mm above the cementoenamel junctio...
