ABSTRACT Among the laboratory CAD/CAM systems available today for fabricating all-ceramic restorations, the Sirona inLab[R] system and its inEos[R] dental digitizer may be the simplest to use and the most [...]

Restorative dental technology requires a team approach to achieve excellence and consistent quality. That team consists of the restorative dentist, the ceramist, and the crown and bridge technician creating the [...]

Following are step-by-step procedures for the CAD/CAM design, milling, and ceramic build-up of a single crown using the IPS e.max system. Following is the laboratory protocol for using IPS e.max [...]

To fulfill the role of partner in the successful dentist-technician restorative team, the technician needs to have a complete understanding of the masticatory system and all possible restorative options. This [...]

The most difficult tooth to shape correctly is a cuspid. Can you share your thoughts on this tooth? A.C. Dallas, TX TRUST ME, it's not just you, but all technicians [...]

One of the greatest challenges of restorative dentistry is communication between the dentist and technician. Many techniques have evolved over the years to improve communication between clinician and lab. Dental [...]

As patients have become more aware and educated about the advances in modern dentistry, we have seen a dramatic increase in the motivation and demand for natural, esthetic, restorative dentistry. [...]

Following are step-by-step procedures for fabricating metal-free restorations using IPS Empress Esthetic veneer materials. 1. Design the wax-up to optimal function and esthetics (Fig. 1). Note: There are two ways [...]

I am considering the purchase of a laser welder. What advantages does laser welding have to offer over traditional soldering? B. W. Palo Alto, Calif. JOINING TWO DISSIMILAR metals together [...]

This column often addresses communication techniques that dentists and technicians can use to produce better restorations. Here, we will discuss the esthetic tissue management of single-tooth implants, which is one [...]

Can you explain the steps or technique you use to restore anterior bridgework when diagnostic models are not available? J.S. Belleville, IL ALTHOUGH IT WOULD BE NICE to think that [...]

Could you detail the steps that you use for creating esthetic posterior anatomy? J.O. Draper, UT ALTHOUGH I ENJOY creating anterior restorations that blend seamlessly with surrounding dentition, my favorite [...]

Please describe the steps you use to create natural tooth texture and luster in ceramics. N.R. Downey, CA THE TIMING of your question is perfect. In my January/February column on [...]

Dear Lee, Could you please describe your thought process in creating natural tooth morphology for anterior crowns? T.S., Layfayette, LA Dear T.S., Due to space constraints, I will only be [...]

The main criterion for efficiently and accurately finishing a metal framework is an accurate, smooth wax-up that has been sprued and cast correctly. Using a proper waxing and casting technique [...]

At a time when bleach shades have never been more popular in restorative dentistry, the new IPS Empress Esthetic E03 ingot expands the laboratory ceramist's selection. With the availability of [...]

Could you please describe how to create an incisal halo for an anterior restoration? T.W. St. Louis, MO THE 'HALO EFFECT' is an optical illusion caused by light bending and [...]

The article discusses the use of digital image capture in dental restoration treatment. The entry notes that the evolution of restorative dentistry involves changing the perception of the dental laboratory as a partnership between the dentist, auxiliaries, and technician. The section explains how the E4D Dentist system is able to automate labor-intensive procedures into a more consistent and precise method. It also examines the treatment of a patient with a missing cast gold restoration and fractured ceramic onlay using the E4D Dentist System.

The article discusses the evolution of zirconia, a unique universal restorative for anterior and posterior applications in dentistry. Topics discussed include research regarding zirconia as biomaterial, the introduction of zirconia-based ceramics as a restorative dental material, the low-wear property of zirconia, and wear of zirconia versus enamel.

The article explores the dentist-technician working relationship in the age of growing computer-aided design (CAD) technology use among dentists. Topics discussed include the use of digital methods in the case of a patient who is in need of a restoration to replace the missing posterior in the maxillary right quadrant and benefits reaped from using the 3Shape restorative design software related to dental implants.

The article offers information regarding the new applications for emerging digital technologies, Zirconia Esthetic Universal System (ZEUS),a zirconium-dioxide material which is ideal for technology-enhanced fabrication technique. It provides remarkable esthetic qualities as its blanks are pre-colored in four shades including pure, light, medium, and intense. It is mentioned that by optimizing the raw material powder and compaction technology, 60 percent light transmission can be archived.
