In clinical practice, an inappropriate occlusion is not a serious matter. It means that you can find out some high or low points on prosthesis straight away. However, this inappropriate occlusion is difficult to find out with occlusal paper. Don't you think so? Of course, it is hard to find the inappropriate occlusal relationship by watching. What should you do? Since it is not possible to check with an occlusal paper as we mentioned above, we would like to recomend "NANPARA" method. What is "NANPARA" method? "NANPARA" method is the remount technique invented by Japanese “Denture master” Dr. Hirofumi Shioda. You can make a diagnosis by this method. "NANPARA" method doesn’t use occlusal paper. The remount technique in general is quite troublesome, isn't it? Dentists can provide that case with a dental technician if they have in-house technicians in their dental offices. But many of them aren’t able to do so. When asking to an outsourcing dental technician, the dentists have to wait for that case and deliver a denture to patients after several days. They make the patients to spend inconvenient time. Thus, some dentists think remount method is not suitable for some practical clinical practices. However, if you think it is in different viewpoint, you could use that pocket of time efficiently while the case would be in a dental laboratory that you outsource. And your chair time could be shorten. Given this idea, you also think this remount method would seem to be a reasonable adjustment method for efficient medical care.
This section explains how to take a bite registration for this remount method.
First, cut the paraffin wax into a strip form with a width of 22 mm to 25 mm.
Next, soften it with flame.
Third, fold twice and shape the block.
Fourth, place the paraffin wax on both sides from the premolar to the first molar.
Then, deliver the denture in a patient's mouth, and make him/her bite it gently to obtain a slightly high bite position.
It is placed on an average value articulator to adjust it. And you could see the differences what you see it on the articulator from what you see in their mouth. This is the softened paraffin wax molar occlusion technique, we call it "NANPARA" method.
1. Cut paraffin wax into 22 mm to 25 mm size for checking bite.
2. Soften paraffin wax with fire.
3. Fold the paraffin wax two times to become about 4.5mm thickness. It means that you make a piece of paraffin wax be three times as thick.
4. Put it on both sides of molar part of a denture and cut it with finger.
5. Deliver it into patient’s mouth.
6. Make a patient bite gently at high bite position. And take it out from the mouth.
7. Mount it on an average value articulator.
8. It happens occlusal contact in anterior part, it doesn't show occlusal contact in posterior part.
However, it is difficult to determine whether the occlusal that you take is correct or not. If you think that it isn’t accurate somehow, then you can try "NANPARA" method. We recommend it. The key point is that the upper and lower midlines are visually overlapped each other in mandibular rest position. The percentage of overlap between the upper and lower midlines is over 90% in that situation. Therefore, we think that the upper and lower midlines are key point when we perform “NANPARA” method and that can be considered a rule. If you are interested in this method, we look forward to hearing from you.
