In the first part, Dr. Bumsu Kim DDS of Yonsei Suite Dental Hospital gave a lecture on the topic of “Modeless Workflow in the Aspect of Dentists”. Dr. Kim explained how the modeless workflow using oral scanners worked in real dentistry with clinical cases. In addition, he described that how dental technicians should prepare for changing trend of dentistry with showing the process of using various digital devices in dentistry.

In the second part, Mr. Kyungjin Kim, owner of Kyungjin Dental Lab, gave a lecture on the topic of “exocad Partial Design & Digital Fit”. Mr. Kim said that he started digital partial dentures two years ago through the digital partial denture seminar of DOF. He emphasized that anyone could get consistent results without difficulty once they started “digital partial dentures with milling”.

While demonstrating the design process at exocad, Mr. Kim explained the points to be aware of designing the digital partial dentures. In addition, valuable know-how gained from many years of digital partial denture work, such as understanding STL files and OBJ files, how to use various tools in exocad’s EXPERT MODE, and approaches to make digital fit easier, were disclosed.

Mr. Min-sik Choi, director of sales team, said, “despite the sensitive situation due to the COVID-19, thankfully, each seminar registration closed early. In order to return your interest and love to DOF, the seminar in September would be held by increasing the size so that more people could attend.

In Jung Hee Lee’s lecture, he emphasized understanding of 5-axis milling machines and its accessories. Basic concept of 5-axis milling machines as well as the description of scanners were also included. “We had to think about the principles of machines. We needed to keep the room temperatures according to seasons and warm up the machine to reduce errors because machines are metal” CEO Lee said. “It’s better to minimize the calibration considering the parts of the equipment” he said. He explained in detail that the maintenance of spindles and components, how to check accessories, check points and precautions when designing actual custom abutments and zirconia prostheses.

Surgical Guide, keep an eye on bonding.

Following to Jung Hee Lee’s lecture, Dr. Hoon Kook Shim, director of Yul Dental Clinic, took over his turn. Dr. Shim introduced the history of surgical guide and its role. He also said that the dynamic system is under development and would be introduced to dentistry. He also explained the surgical guide system and how to use it for each manufacturer. Dr. Shim said, “I thought the surgical guide would become more and more popular. It was better to be aware of the current situation and future direction because it could be used in public facilities as much as possible.” He also introduced limitations of intra oral scanners and the concept of adhesion and bonding. “Recently, we used collagen fiber with the Dentin bonding concept,” he said. “I recommended that dentists and dental technicians need to discuss regarding bonding.”

[Media] DOF held “One-Step Milling” seminar successfully.

By Latest News

DOF announced that it successfully held the first seminar of 2021 on Saturday February 27. This seminar was about “One-Step Milling”, a new groundbreaking method that dramatically reduces working hours and improves the accuracy of prostheses by simultaneously producing custom abutments and suprastructures.

The seminar was held with the minimum number of people to prevent the spread of COVID-19. In the first part, Jung Hee Lee, CEO of Joyful Dental Studio, gave a lecture of “Custom Abutment & Zirconia One-Step Milling Analysis,” and in the second part, Hoon Kook Shim, director of Yul Dental Clinic, gave a lecture of “Digital Milling in the Aspect of a Dentist”. Jung Hee Lee and Hoon Kook Shim generously shared their know-how accumulated by using actual clinical cases and continued discussions with participants.    

Jung Hee Lee, who conducted a lecture on one-step milling, said, “many people have thought that one-step milling is only possible with a CNC lathe. When CRAFT 5X’s one-step milling applies to various clinical cases, I experience that CRAFT 5X never falls behind the CNC lathe in terms of quality of customization, but rather shows better results. The era of one-step milling is now opened in general dental labs and dentistry. As prosthetic techniques by intra oral scanners are diversified, modeless techniques are becoming more and more popular. In the midst of this trend, I believe that one-step milling would be an essential technique for technicians, so I have prepared correspondent lessons.”

Song Jae Lee, director of DOF, said, “even though we are sensitive to COVID-19, many people show interests in our seminar that application was closed early. We will continue to deal with the contents that can be helpful to our customers through various types of seminars, so please keep your eyes open.”

Meanwhile, DOF will hold a “Digital Denture Seminar” at Gangnam Education Center in Seoul on Saturday April 24. In the first part, Professor Kwan-tae Noh, Kyunghee University’s Dental Hospital will give lectures under the theme of “Digital Denture Design,” and in the second part, Chan-doo Kwon, director of Able Dental Lab will give lecture of “Denture Story”.

Full Upper All on 5 implant case with my dental friends.
 
Patient had been using Denture for 30 years and she couldn’t smile because she didn’t like her look with her denture on, so she really wanted to get her confident smile back.
 
Dr. Daniel Fortino placed 5 implants on upper. Dr. Joseph and I put fixed bridge on same day.
A few month later, Dr. Joseph took impression with Verification Jig which is the most important process.
According to the conversion denture, I delivered Prototype to check the bite relations and midline, the Dr. Joseph said it was way off.
I wanted to get more information on chairside to verify the midline, so I used the DOF SNAP face scanner in order to get more accurate information for final restoration.
After the visit there was a small mistake, I made during the PMMA stage. I fixed the midline according to what I checked on chairside instead of following the face scan guide.
For the final restoration, I fixed the midline according to the face scan guide and after that case was simply done.
 
Finally, I could deliver the case to the patient.
Patient was simply happy with her natural smile and that was just priceless.
 
With the simple mistake I made this time I learned my lesson and I think I can do much better job with my new digital workflow.

The team in this case :
  • Dental technicians from Dali’s Dentech – George Berlovan (CAD/CAM) & Melinda Györi (composites/ceramics)
  • Dr. Adam Dragos
  • Laser sinter by Simo’s Dental
Using the DOF’s Freedom HD scanner and exocad, we started with a printed PMMA as a tryin over premills as primary telescopes. This was later transformed into a milled ML PMMA as a travel prosthesis and the design was reduced to make 2 telescopic bridges with composites over titan substructures with galvano as secondary telescopes.
