Mobile end devices have long since found their way into the dental practice and for good reason. They inspire through technology and design and provide effective support in many work situations on demand. But there is more to it than just the end device: The right app makes all the difference! CAMLOG has developed an app that has it all; information about products, application and science make patient education, treatment planning and many processes in the organization a pleasure.
According to recent studies, the Apple And the desire for a stable system may Intuitive user interface, integration of iPad is particularly popular among be the motivation for some practice typical Apple gestures and functions, as doctors. About one third are already using owners. So for us, the decision for an iOS well as a good "flow" were also important one and the trend is only increasing. Its app was easy. The elegant design of the parameters in developing the app like almost unlimited mobility makes the tablets fits perfectly with the design of the the capability of providing all relevant tablet unbeatable compared to a laptop CAMLOG app designed according to the information in one application.

The advantage lies in the hands
The result is clear to see and experience. The look & feel of the app make it an unmistakable CAMLOG tool – and wanting more. If you've ever gotten a hold of it, you may never want to put it down. Every tap provides the right content to best support dentists in their work.
The main focus is on the products and all information about their practical application. Tapping on the Product section provides access to information about the CAMLOG® and CONELOG® implant lines. The blue-gray double icon provides a clear view of all aspects important in making a decision for a suitable implant system and zeros in on the point: two implant systems – one surgical solution! The detailed view explains the product features and key benefits for the user in a straightforward, concise manner. The respective catalog with complete product details is in the immediate vicinity.

From the Settings menu, all documents can be downloaded in a single process, making them available online and offline. The benefits of mobility are thus maximized. A particular highlight is the "My CAMLOG Area" where you'll find something very special; easily integrate your own documents by synchronization from your Dropbox folder. You then have access to what you need – always and everywhere.
What is "Dropbox"?
"Dropbox" is an online service that lets you save files in a central location that you want to access from anywhere. It can be very practical, for example, to save photos from your own smartphone in a folder that you can access on your PC at home. You can also save documents in a Dropbox folder and share access to anyone you want. No more unwieldy e-mail attachments, USB sticks or CDs – you can give anyone access to your files by simply sharing the respective folder. Dropbox offers 2 GB of storage free and additional storage is available for a fee. Details are available at: SCIENTIFIC / CLINICAL RESEARCH

It comes from the video compendium "Implantatprothetik VIER TEAMS – IHRE KONZEPTE UND LÖSUNGEN" (Implant-supported Restorations FOUR TEAMS – THEIR CONCEPTS AND SOLUTIONS) published this year by Quintessenz Verlag in four volumes. Volume 4 by F. Beuer, M. Stimmelmayr and J. Schweiger focuses on innovative treatment concepts for fixed prostheses on implants using CAD/CAM technology. The video compendium is available from CAMLOG as a DVD or Blu-Ray disc.

For reasons of time, many patients want treatment in as few sittings as possible. For this purpose, implant positions can be registered, for example, right after implantation. When exposing the implant site, the final abutment is then attached. This has the additional advantage that the connective tissue attachment does not have to be detached again. The tissue can mature without disruption with potentially beneficial effects on the peri-implant situation [1]. This proven protocol has recently been further developed using CAD/CAM technology [2]. The final abutments can be fabricated from the biocompatible zirconia [3]. The preparation boundaries can also be specified in the software for the temporary restoration relatively accurate at the level of the gingival margin.

A forward-looking and open-minded attitude towards modern technology and a high sense of tradition and traditional values are not mutually exclusive.

Beat Krippendorf, lecturer in strategic and operational marketing, provided a fantastic end to the Swiss Dental Technology Congress 2012. His main focus is the "principle of humanity" and the belief that good relationships affect business success sustainably. According to Krippendorf, good relationships are less a question of technical competence and more a question of attitude and personality or in his own words, the "own culture". "People do not care how much you know until they know how much you care," is just one of his striking theses.
With this, an outstanding event came to a deeply inspiring and motivating end. We can already look forward with eager anticipation to the cotinuation of the Swiss Dental Technology Congress and the coming motto! HIGHER, FASTER, FARTHER!
