Technology Spotlight: Laser-Sintered Crown Copings

Volume 11, Issue 4

Clinical Case Report: iTero® Digital Scanning Technology and Tooth-Supported Surgical Guides

Volume 4, Issue 2

Technologies such as digital intraoral scanning, CAD software and digital treatment planning are enhancing the precision of implant therapy while producing predictable restorative outcomes. Patient anatomy can be understood with remarkable detail through the digital collection of scanning data, and cases can be virtually planned using computer software. The following case exhibits the ability of […]

Back to the Future: The IPS e.max® Screw-Retained Crown

Volume 3, Issue 2

In processing restorations for more than 160,000 implant cases, the implant department at Glidewell Laboratories has accumulated a unique understanding of the industry as a whole. Among the recent trends observed at Glidewell Laboratories is the demand for monolithic screw-retained restorations such as the IPS e.max® screw-retained crown (Ivoclar Vivadent; Amherst, N.Y.). While screw-retained restorations […]

CAD/CAM Technology in Implant Abutment Design

Volume 2, Issue 3

Custom abutments provide numerous clinical advantages over prefabricated abutments. Utilizing CAD/CAM technology, the dental technician can precisely design and fabricate the restoration according to the clinician’s prescription. Modifications can be made to the transgingival section, the margin and the angle of the abutment. The base, height and taper of the abutment can also be designed […]

Using CAD-Designed Cast Frameworks to Reinforce Overdentures

Volume 2, Issue 2

One of the complications that can occur with implant-retained or implant-supported overdentures is fracture of the acrylic base. This primarily happens in areas of high stress when there is lack of vertical space and, therefore, an inadequate thickness of acrylic. Fractures commonly occur in the acrylic on either side of the attachment or when the […]

A Technique for Obtaining Accurate Full-Arch Implant Impressions

Volume 2, Issue 1

One of the most critical requirements for implant-borne restorations is a passive fit of the prosthesis. If this is not obtained, the resulting stress could result in loosening of the abutment screws or, in the worst-case scenario, damage to the implants or surrounding bone.1-7 In the past, casting large frameworks resulted in inherent errors. Frequently, […]

Inclusive® Custom Abutments Using 3-D Virtual Design

Volume 1, Issue 2

It seems that everywhere you turn today, people are promoting one or another form of CAD/CAM application. This technology often brings synergy and efficiency to the lab, but the ultimate benefit to the dentist is not always immediately apparent. In the video above, I will demonstrate how this technology allows Glidewell to provide precision-milled CAD/CAM […]

Screw-Retained Denture with CAD/CAM Framework

Volume 1, Issue 1

Preoperative Appointment The screw-retained denture, also known as the hybrid denture, has been the standard fixed-removable restoration for edentulous mandibles for more than 40 years. I used this prosthesis extensively 25 years ago. However, after experiencing problems obtaining a passive fit accompanied by routine screw loosening and fracture, I stopped providing it to my patients […]

CAD/CAM Porcelain Fused to Captek™

Volume 1, Issue 3

For years I have wondered why some seat appointments go so smoothly while so many others take so long. I never could figure out if blame fell on the patient, the lab or me. One thing I never considered was the material. The truth is, the limitations of the materials and techniques that labs are […]
