What is "Inaba-style Konus Krone"?

In recent years the telescope system, dentures developed in Germany, has frequently been picked up in dental magazines. This can only be a consequence of the IPSG 20th Anniversary Special Lecture Meeting, in which Dr. Shigeru Inaba worked as a representative.

Konus Krone gained wild popularity in the 1980s. But after only 10 years its popularity waned. The technology experienced a lot of troubles and its reputation diminished.

It is thought that the cause of these troubles was that the design, manufacturing method, metals used, applicable cases, and other such factors were not uniform in the Konus Krone method.
As a result the technique fell out of mainstream use.

It seems that in recent years dentists are taking another look at Konus Krone. But even still, I get the sense when reading that there is a lot of misinformation going around about this technique.

Dr. Inaba studied Konus Krone directly at its source in Germany.
Professor Karlheinz Koerber wrote Konuskronen, the original textbook on the Konus Krone technique.
Of course he wrote this book in German, but Dr. Inaba has read this Konus Krone text book from cover to cover so many times that his copy is now worn and tattered.
This book is filled with designs, manufacturing methods, applicable cases, contraindications, resolutions, and many other topics related to Konus Krone.
There are a few inconsistencies between the contents of this book and the contents of information that has been spreading throughout Japan.
Konus Krone dentures are successful because of the many rules and manufacturing methods used in making them. They are not dentures that can be made using individual styles.

But even so, there is little anyone can do to stop these new methods from proliferating.

Dr. Inaba learned Konus Krone in Germany from first-hand information and follows the procedures laid out in the textbook precisely. This has led to wonderful treatment results.
I wish to preserve an orthodox version of Konus Krone that follows the original textbook. This is what I refer to as "Inaba-style Konus Krone" when comparing Dr. Inaba's technique with other Konus Krone techniques that are spreading throughout Japan.

First, the reputation of Konus Krone that spread among clinicians during the 1980s suffered. Also, here we will have Dr. Shigeru Inaba explain exactly what the correct Konus Krone treatment method is.

1.The history of the telescope system and misconceptions about Konus Krone

 
In Japan this technique is only known as Konus Krone, but in Germany there are many different kinds of telescope systems. It is extremely regrettable that incorrect Konus Krone treatment methods have spread across Japan and have caused the reputation of telescope dentures as a whole to suffer.

The Konus Krone textbook was translated into Japanese in the 1980s and for a while it was very popular among a portion of dentists here. But after only about 10 years its popularity waned. There were many problems with the treatment method and its reputation suffered. It is thought that the cause of these troubles was that the design, manufacturing method, metals used, applicable cases, and other such factors were not uniform in the Konus Krone method. As a result the technique gradually fell out of use.

2. How Konus Krone is handled in Germany

 
In Germany, Konus Krone is just one of many types of telescope systems. There was nothing particularly special about this treatment method.
I learned that by using not only Konus Krone, but also Riegel telescope, Resilience telescope, Anchor Band telescope, and a few other telescope techniques, I could treat almost any case. Riegel telescope especially proved to be applicable in many cases using both rotating Riegel and revolving Riegel. I was able to actually experience clinical care in Germany where these telescope systems were used. That experience is what I base my own clinical care on even today.

3. How Konus Krone is handled in Japan

 
When I returned to Japan in 1980 this technique was beginning to spread among clinicians under the name Conus Crown. But the actual clinical procedures and manufacturing method was very different from what I had seen in Germany.
The metal being used in Japan was a gold and silver alloy called palladium. It kind of looked like the gold used in Germany, but it was not the same. At any rate it was quite different from the procedure that I learned in Germany.
The purity of the gold and silver palladium alloy degrades after long use. After seeing this I decided that I needed to spread the correct 'Konus Krone' technique so I published 'Konus Krone' and 'Riegel telescope' in the Shofu Color Atlas.

One big difference is that Japanese instructors were teaching that dentists should just remove the nerves from the teeth because of the large amount of filing necessary. Removal of nerves from the teeth became a big problem as the teeth would crack and the reputation of Konus Krone suffered greatly. In Germany, one of the rules of Konus Krone is that only teeth with nerves can be used as support foundations, but in Japan this was the complete opposite.

Moreover, it is necessary to understand the fundamentals of denture design in order to protect teeth, but in Japan these fundamentals were widely unknown. This was especially true for the 'torsion bar' and 'sparte', bed designs that prevent the breaking of teeth. These techniques were completely unknown in Japan and in fact no measures were put into place to prevent teeth from breaking.
With these fatal flaws, the number of dentists who treated with Konus Krone grew fewer and fewer.

4. How Konus Krone should be used from now on

On the other hand, there are many cases of the Konus Krone treatment method being used correctly and patients happily using their dentures even 30 years after first receiving treatment.
When I was studying under the auspices of Professor E. Koerber as a visiting professor at Tubingen University in Germany, I was fortunate enough to have experienced the telescope system being used to treat many cases and receive information first-hand.

It is our hope to continue to expand our offering of clinical services. Konus Krone is not the only type of telescope system that we use in our clinic. We also use Riegel telescope, Resilience telescope, and many other treatment methods chosen to suit each individual case. Moreover, in recent years we have been able to combine telescope system treatment with implants with favorable results. So we are very excited about future developments.

---------------------------------------------------------------------------------

An article that Dr. Inaba published at the time called 'Orthodox Konus Krone' has been made into a booklet!
It speaks in detail about the correct method of treatment. It contains details about the correct treatment method including the use of an occlusial core, the Konus milling machine, the correct impression method, set method, and many other such procedures.
The fundamental design of Konus Krone can be suited to all partial dentures.
This booklet is unattainable anywhere else. Please pick up a copy for your own reference (intended for dentists).
