Summary
This report details two workflows for creating computer-aided design and computer-aided manufacturing (CAD-CAM) milled complete dentures. These methods offer efficient digital fabrication options for dental prosthetics.
Area of Science:
- Dental prosthetics and materials science.
- Digital dentistry and manufacturing.
Background:
- Complete dentures (CDs) fabrication traditionally involves manual steps.
- Advancements in computer-aided design and computer-aided manufacturing (CAD-CAM) offer potential for improved denture production.
- Digital workflows can enhance precision and efficiency in prosthodontics.
Purpose of the Study:
- To describe two distinct workflows for fabricating CAD-CAM milled complete dentures.
- To present a manufacturer-independent technique for CAD-CAM milled CDs.
- To highlight a digital workflow for both CAD-CAM milled CDs and interim removable partial dentures.
Main Methods:
- Workflow 1: Employed conventional clinical steps with a custom modified tray for a manufacturer-independent CAD-CAM milled complete denture fabrication.
- Workflow 2: Utilized a nearly digital approach for manufacturing a CAD-CAM milled complete denture and a milled resin interim removable partial denture.
Main Results:
- Successful fabrication of CAD-CAM milled complete dentures was achieved using both described workflows.
- The manufacturer-independent workflow demonstrated feasibility with conventional techniques.
- The digital workflow enabled efficient production of both complete and interim partial dentures.
Conclusions:
- Two viable workflows for CAD-CAM milled complete denture fabrication are presented.
- Digital dentistry approaches, including CAD-CAM milling, offer effective solutions for prosthetic fabrication.
- These workflows contribute to the advancement of digital prosthodontic techniques.

01:27C4 Pathway and CAM
48.9K
Most plants use the C3 pathway for carbon fixation. However, some plants, such as sugar cane, corn, and cacti that grow in hot conditions, use alternative pathways to fix carbon and conserve energy loss due to photorespiration. Photorespiration is the process that occurs when the oxygen concentration is high. Under such conditions, the rubisco enzyme in the Calvin cycle binds O2 instead of CO2, which halts photosynthesis and consumes energy.

172
Since the early 2000s, computer-mediated communication (CMC) has grown rapidly, playing a crucial role in self-development. A key distinction between CMC and real-life interactions is the lack of a physically present partner. This absence makes non-verbal cues such as facial expressions, body language, and paralinguistic signals unavailable in CMC platforms like email, instant messaging, or social media. The lack of these cues can create ambiguity and complicate how feedback is interpreted.The...

02:46Uncertainty in Measurement: Reading Instruments

Counting is the type of measurement that is free from uncertainty, provided the number of objects being counted does not change during the process. Such measurements result in exact numbers. By counting the eggs in a carton, for instance, one can determine exactly how many eggs are there in the carton. Similarly, the numbers of defined quantities are also exact. For example, 1 foot is exactly 12 inches, 1 inch is exactly 2.54 centimeters, and 1 gram is exactly 0.001 kilograms. Quantities...

03:34Uncertainty in Measurement: Significant Figures
80.9K
All the digits in a measurement, including the uncertain last digit, are called significant figures or significant digits. Note that zero may be a measured value; for example, if a scale that shows weight to the nearest pound reads “140,” then the 1 (hundreds), 4 (tens), and 0 (ones) are all significant (measured) values.

According to obedience research, we may harm others under the forceful pressures of an authority figure (Milgram, 1974). How about if the inappropriate orders were delivered with less force? The increasing interdependence between nurses and physicians compelled Hofling and his colleagues to explore nurses’ reactions to a potentially harmful medical request made by the perceived authority figure, the doctor (Hofling, Brotzman, Dalrymple, Graves, & Pierce, 1966). In this situation,...
