| special Koubi: I would like to briefly address the previous two questions. Generally speaking, you have two realities. One is the patient’s expectations. Patients would always prefer a customised smile, not a standardised one. And the second one is the technician’s abilities. Most lab technicians have a specific signature, their own style, and they pretty much repeat it with every case. I am talking about the majority of technicians, not the top professionals. The beauty of the software is that you have a digital library and you can in- clude as many tooth shapes and forms as you like. And after that, you can play with the software and make some mod- ifications. The problem is that most dentists are not able to experiment with the software because we don’t have the knowledge and ability to do it. That’s the main problem with smile design: the dentists are not able to experiment with the software and the lab technicians have one and the same signature. Rebel provides a solution, giving you the advan- tage of outsourcing the headache of smile design. We have to be realistic: most dentists are not able to use the software or Keynote properly; we are dentists, not fancy speakers, or we just don’t have enough time to spend hours in front of the computer. The ceramists don’t have the knowledge or ability to create all the different tooth morphologies be- cause there are more than 12,000 different tooth shapes. That is where Rebel comes in; its algorithm supports you in this task. Returning to the question, the benefit for den- tists is that it is so user-friendly—you just plug and play! Rebel saves a great deal of time and gives you a quality product, so it meets every dentist’s needs! Mr Kuday, would you like to add something to this topic? Kuday: As a dental technician, I would like to say that digital workflow is a tool you can always rely on. If you integrate digital technology into your everyday practice, it definitely raises the quality of your work. We dental tech- nicians study anatomy, biology and morphology and are a part of the team, so if dentists don’t respect our work as lab technicians and don’t send us all information needed to create beautiful, nicely fitting prosthetic restorations, then our hands are tied. Fortunately, I am lucky to work with dental experts like Drs Gurel and Koubi, who appreci- ate my work in the lab. All of the precious information that they register from the patient’s mouth, the questionnaire in Rebel, give us an idea of how to follow nature. At the end of the day, we are a team; we sit down and work together in order to create a beautiful job as partners. Koubi: With Rebel, we are not talking about replacing the lab technician; we are talking about supporting and assisting him or her. It is very important to keep that in mind. Rebel is a very useful tool to improve the quality of the technician’s work in order to create even more beautiful restorations. Gurel: One other thing: thanks to Rebel, even more dentists who were previously afraid to work in the aesthetic zone will go into aesthetic dentistry. Imagine that every patient who needs an aesthetic treatment is like an empty canvas. You need to create an artwork there and not every dentist is capable of doing that. Rebel gives you the op- portunity to create a masterpiece without worrying about how to use Rebel. All other programmes, as Stefan and Hilal have already said, require detailed computer knowledge in order to create proper smile designs or a great deal of time to work with digital libraries, to position the teeth and to establish a really aesthetic smile. For the dentist to be able to achieve a perfect smile with a single mock-up is a completely different story. That’s the beauty and ease of using Rebel. The effect of integrating Rebel into the dental world will not be erasing and replacing all den- tal technicians. Instead, it will create a huge community of dentists doing aesthetic cases, which will increase the number of veneers, crowns and bridges to be made. As an end result, more dental technicians will be needed to cope with the rising needs. You have touched on some advantages of digital tech- nology, but what are its limitations? Gurel: Well, there are always limitations. First of all, it won’t work in extremely crowded dentition. We shouldn’t expect miracles. Rebel can cope with cases with a reason- able initial situation, for example minor crowding or minor spacing. It is not mandatory for the restorative technique to be additive for every case. That’s another great advantage of Rebel, meaning that if a part of a tooth is protruding out of the aesthetic arch, the software doesn’t take that into account. It will place the original shape over the ideal arch position, leaving that part outside. The advantage of this is that in a traditional system in order to put the wax-up into the patient’s mouth we have to first cut the protruding edge of the tooth and then make the mock-up, which means we have already started prepping the teeth and if the patient is not satisfied, it will be a problem. With Rebel, you can transfer the mock-up into the mouth even with this crowd- ing and then explain to the patient that if he or she doesn’t want the dentist to prep this tooth then he or she needs to undergo an orthodontic treatment. The possibility of having this visual information and communicating with the patient enables you to achieve superb outcomes. Koubi: We need to have a very clear vision regarding the digital technologies because it is a reality already. In order to be good with digital technologies, you need to be a skilful driver and manager of the whole process because, as we have already mentioned, digital technology serves you as a tool. But you and your lab technician need to be well educated. That’s the basis of your teamwork. Sometimes, people are confused because they believe digital tech- nologies will provide them with all of the clinical solutions, but that’s not true. It only supports us in our work; it speeds it up and improves its quality. We use artificial intelligence to simplify our life, but not to replace the human with his or her mind and knowledge. 08 CAD/CAM 4 2018
