Fit for 3D printed frameworks
Article Date: Feb 21, 2017 Vol 16, No 1
ZT Frieder Galura

 When casting digitally produced cast partial frameworks made by rapid prototyping or milled out of resin or wax
blanks, the main problem for many labs is an unsatisfying fit of the final denture. Normally the framework is virtually esigned on the scanned master model in the scale of 1:1; owever, the casting contraction is not taken into account in his processing step. When working with the conventional ethod, the wax-up is made on a refractory model, which is lready oversized by the setting expansion of the investment aterial.

Non-prep veneers to correct peg shaped teeth
Article Date: Feb 21, 2017 Vol 16, No 2
Vanik Kaufmann-Jinoian

 Peg-shaped tooth occurs almost exclusively in the wisdom tooth or lateral incisal area. This anomaly is particularly unsightly in the anterior region, and many patients wish to have it corrected in order to close the tooth row. This is usually carried out by building up the area with composite or using veneers. Below l will demonstrate a patient case that was solved to perfection using the new CAD/CAM glass ceramic Vita Suprinity.

Prosthetic Design, Aesthetics, 3D Gnathology-From 2D to 3D. Planning cases with the use of 3D photographs with facial scanners (Part 1
Article Date: Feb 21, 2017 Vol 16, No 2
Giuseppe Rampulla & Andrea Pelosi

 Thanks to the evolution of digital tools such as 3D scanners, the increasingly widespread and evolved use of the
Cone Beam CT, the CAD/CAM programs and the new materials, we are witnessing a "revolution" in the design and construction of dental prostheses. This article aims to illustrate the latest news on aesthetics and function from a diagnostic and therapeutic point of view. The new images digital technologies, 3D photography, Cone Beam CT also allow performing diagnostic and prosthetic designs that would have been difficult to obtain until a few years ago.

Reshaping Canines to Create Lateral Incisors
Article Date: Oct 13, 2016 Vol 15, No 8
Vanik Kaufmann-Jinoian

 After missing wisdom teeth, agenesis of the upper lateral incisors 12 and 22 is the second most common cause of
congenital hypodontia, i.e. hypodontia that is unrelated to an accident. For a young person in particular, such as the 18-yearold patient shown here (Fig. 1), an anomaly of this kind is often associated with a psychological burden. The ‘Twilight’ look has an enormous impact on self-confidence and reshaping the canines to create lateral incisors seemed an appropriate course of action.

A classic of dentistry in changing times
Article Date: Sep 13, 2016 Vol 15, No 7
Stefan Tiehe

 For decades,the art of dentistry has gone so far in the dental technique of the removable partial denture,
that the precision of the casts that can be obtained is so far unequalled.
The dental industry has contributed in this development through the finetuning of highly efficient methods and materials. Laboratories and industrial partners have achieved together the objective that the removable partial denture manufactured in the traditional manner is for the moment the extent of things in way of profitability and efficiency.

SYNERGY: Case reports
Article Date: May 10, 2016 Vol 15, No 5
Cristian Petri, Dental Technician

At first (beginning) the CAD was a closed system, with limited possibilities, such as: crowns and bridges prosthetic restorations, copings, primary telescopes etc. The milling machines had 3 or 4 axes, and the milling materials were limited to: Cr-Co, Titan, Wax, PMMA and opaque zirconia, all very expensive. The CAM was simple limited licensed software. Now we are in the position to build in CAD: hybrid abutments on implants, customized abutments, secondary telescopes, veneers, surgical guides, implant superstructures, wax ups, attachments, removable partial dentures, complete prostheses.

Two similar working processes in one digital step: Telescopic crowns using CAD/CAM
Article Date: May 10, 2016 Vol 15, No 5
Kay Uwe Risch

Dental technicians can no longer compete with the quality produced today by CAD/CAM, with their only advantage, in the long-run, being their ability to fine-tune the aesthetic details. The manual manufacturing of telescopic crowns (TCs) is a well-known production technique, but it is still not made any easier by PC-based production, because the result is not individually adjustable for the processing of secondary parts; the fit can only be set to "loose" or "tight".

CAD/CAM Technology Supporting Successful Implant Therapy
Article Date: Oct 19, 2015 Vol 14, No 8
Suheil M. Boutros and Manuel Fricke

Educational objectives – To cover the properties of Trabecular Metal and its suitability for use in dentistry and toexplain the process of CAD/CAM design when constructing an bar-supported removeable over denture. Expected outcomes – To understand the various factors in clinical success and appropriate fit when constructing a bar-supported removeable prosthesis and to appreciate the flexibility and capabilities of the CAD/CAM process.

100% CAD/CAM Prettau Zirconia bridge
Article Date: Sep 21, 2015 Vol 14, No 7
Evi-Maria Tauber and Dr. Julie Elpers

The patient had previously received an implant-supported Prettau Zirconia mandibular restoration, produced by our laboratory to the patient’s complete satisfaction. She now requested a high-quality fixed implant-supported restoration for her maxilla as well. The upper and lower jaw were to be a perfect aesthetic match.

Rehabilitation of a DOCS Patient with Complete CAD/CAM Dentures: A Case Study
Article Date: Sep 21, 2015 Vol 14, No 7
Les Kalman, B.Sc.(Hon), D.D.S. & Roocha Vyas, B.D.S., R.D.H., D.D.S.

A Dental Outreach Community Service patient is rehabilitated with Dentca’s CAD/CAM dentures. The clinical and laboratory procedures offer the clinician another option for complete denture delivery that is both efficient and accurate. The expedited approach has a place with outreach dentistry, providing patients with form and function in a timely manner.

Petr Hajný

Patients who visit the dentist with the wish to have their smile enhanced would like this to happen in a fast, efficient and complication-free manner. Aesthetic and functional rehabilitation of the anterior dental arch and occlusal height can be completed in a single day using IPS e.max CAD lithium disilicate ceramics (LS2) in combination with CAD/CAM technology (the CEREC system by Sirona, Germany, was used here). We use T-Scan technology (Tekscan, USA) to assess the articulation and this method has enabled us to achieve excellent results.

Model Casting Without Casting?
Article Date: May 26, 2015 Vol 14, No 5
Stefan Tiehe

Unimaginable: As the name suggests, a model casting without casting is hard to imagine. The ongoing development of CAD/CAM technology means that it is now possible for us to produce these bracket constructions by means of additive and subtractive processes. Measuring, blocking out and modelling can be carried out virtually, and sintering methods mean that embedding is no longer required. However: How does this impact the quality?
