Restoration & Prosthetics

LED+ Innovation from W&H
The maximum LED technology: the new W&H Synea turbines, and Alegra turbines and contra-angle handpieces as well as surgical straight and contra-angle handpieces with LED+! Dentists have welcomed this innovation and many are using the LEDs from W&H!

What´s LED+?
LED stands for ´light emitting diode´. When electricity flows through the LED, it emits a particular wavelength of radiation depending on its structure and material.

Synea LED+ Turbines
These LED turbines are good products which provide brighter lighting than similar tools that use bulbs. In fact, bulbs often fail us...

User Report Alegra Contra-angle LED
User report by Franck DIEMER, France. I was very impressed with the new Alegra contra-angle handpiece WE-99 with generator technology. The daylight quality, relatively "white" LED light provides brighter illumination than a conventional halogen light, which helps to improve visibility and working comfort.

Endodontics

Entran - observations after 12+ months
Dr. Christoph Kaaden, Endodontology specialist from Munich, Germany. Without doubt, the best change to date has proven to be the introduction of the “Entran” battery-operated Endo contra-angle handpiece from W&H. My practice has two of these contra-angle handpieces. At last, we are now able to carry out root canal preparations using a highly ergonomic device, without the hindrance of a foot control or a mess of cables.

The effectiveness of dental treatment depends largely on how well the oral structures that are to be treated can be recognised. Delicate instruments with fibre optics and press button chuck systems are available to dentists in conservative/prosthetic dentistry today.

Implant planning with standardised spacers
The application of intraoperative positioning aids in the form of implant drilling templates allows those who are new to implantological procedures, and also experts, to work confidently when carrying out targeted prosthetic oriented implant insertion.
User report: Dr. Neugebauer, Dr. Karapetian, Dr. Lingohr, Univ. Prof. Zöller (Cologne)

Implantology distance control - Will it replace the drilling template?
An innovative implant positioning aid makes it easier to find the optimum implant position – will it therefore replace the drilling template?
User report: Dr. Lang, Dr. Michalides (Bremen)

Positioning implants
A new system for positioning implants

Sterilization, hygiene & maintenance

The main advantages of the new Lisa 500 autoclave
In the following interview, Elodie Laurent, hygiene manager at the « Espace Sourire » dental clinic at Six-Fours in France, talks about the advantages the new Lisa 500 autoclave brings to her everyday work, especially in so far as the made to measure cycle and traceability system are concerned.

User report Assistina by Dr. Caparas, Quezon City (Philippines)
We have been using the Assistina in our practice since August 2010. Previously we used oil spray to maintain our instruments – which in hindsight was clearly very expensive and time-consuming. The advantage of the Assistina? The device is easy and safe to use. The instrument spray ducts are cleaned and oiled automatically and correctly, and nothing else is required of the user. It is a good feeling not to have to worry about the process. The immediate success of the new method of instrument maintenance was obvious with the smooth operation, lack of noise and the extended working life of our instruments.

Tested for you - Assistina 301 plus
I wanted a device that is easy, fast and safe to use, that is economical and also prevents the escape of oil during treatment. That is why I selected the Assistina. And it has paid off. Report by Ms. Kornkaew Aimaram (head nurse, Dental Department of Thonburi Hospital, Bangkok/Thailand)

User report on LisaSafe and LisaWare
Dr Josh Pond who operates the “All about Teeth” dental surgery in Townsville, Australia, gives his comments on the use of the W&H LisaSafe label printer and the LisaWare software in conjunction with the Lisa 500 autoclave to link instrument tracking with his paperless patient records.

Assistina makes handpiece cleaning and maintenance easy
Senior Dental Assistant Tracey Carroll is one of a growing number of users of the W&H Assistina - regarded as the 'Rolls Royce' in handpiece cleaning and maintenance systems. Tracey has worked with Queensland practice, The Endodontic Group for 15 years and has seen many changes in that time in dental equipment. She says it would be difficult to think of one piece of equipment which has made such a difference to the daily routine of auxiliary staff as the W&H Assistina.
