HOW TO AVOID DOING A SINUS LIFT.


K. F. Chow BDS., FDSRCS May 7th, 2017
Dear Dr A,
I guess you are another fictitious Doc with an alphabet. Nevertheless, it is an interesting question.
If you do not want to do a sinus lift, any reason will do though it might not be a good one. I myself once did not want to do it because I hated having to make a large opening into the sinus! And if I can avoid it, I did. So I tried crestal lifts invented by Summers. Works, but often found myself having to spend more time than if I just did a lateral window which is more sure and definitive. There are various ingenious ways nowadays, the latest seem to be the “hatch” technique with a special off centre drill.
However, if you want to avoid all these, there are several ways to avoid a sinus lift altogether:-
* Do a conventional bridge on adjacent teeth. Use the tooth in front and the tooth behind the edentulous space. Or a cantilever might work.
* Place an implant in the tuberosity where there is usually more than enough bone and join it to the natural tooth just anterior to the edentulous space.
* Or use MINIs! Do a tripod. 3 minis with the tips cut off at 5mm length, and build a crown on it.
* 2 or 3 Minis carefully threaded into the walls of the sinus on the buccal and the palatal where there is usually 3-5mm thickness of bone. These technique requires a lot of skill and experience though.
* Use short large diameter fixtures from Bicon, Endopore or some of these Korean makers that come in diameters up to 8mm!
* Or like Dr Richard Hughes suggest…. place in a subperiosteal.
Now all of the above require quite a lot of skill and experience…..maybe you might just want to learn to do a lateral window sinus lift which actually, once you get the hang of it may be actually simpler and surer in results!
Cheers.

Maintenance of Hygiene for a Minidentalimplant Bridge

Gambar
Maintenance of hygiene for a bridge is important. This minidentalimplant bridge can be flossed anteriorly and posteriorly and also in between the implant abutments. The bridge is designed so that the interproximal clefts are generally between the mini dental implants. Thus it is important not only to place the minis parallel but also precisely in the middle of where a normal tooth is expected to be. This will lend itself to ease of bridge design for the technician as well as ease of flossing in between the implants with the help of a bridge cleaner. The narrow diameter of the minis results in a corresponding narrow transmucosal passage of the dental implant as it traverses the gum and emerges into the mouth. Logically then, it will have a lower chance of infection and peri-implantitis as compared to conventional larger diameter implants especially accompanied by an aesthetic emergence profile that demands a broader transmucosal passage especially at the point where it emerges into t...

Numbness After Implants | OsseoNews Discussions on Dental Implants

Numbness After Implants | OsseoNews Discussions on Dental Implants : "Dr Amayev September 11th, 2006 No matter what kind of surgeons you are anything could happen .Of course we must try to ovoid any possible complication to our patient and treat them with respect but sometimes complication may happen. In order to avoid any possible complication we should just stop what we are doing as been previously mention by Dr Kfchow. I don’t believe that there is a dentist or another type of medical professional or any other profession who never had a complication. We all humans and if we did something we have to try to resolve and help that patient in any possible way if we can. From what Lerry or Ben told us, I don’t know you are a doctors or not but if you are it seems like you both the best and never had any complications in your practice. If you didn’t I am very happy for both of you. Never say this may not happen to you ,look in a future you still practicing. Think about that. May be yo...

REMOVABLE FALSE TEETH FOR THE UPPER JAW

K. F. Chow BDS., FDSRCS   July 19th, 2010 If you are placing 5 conventional implants, you might as well place one more to make it 6 and have a fixed prosthesis. A fixed prosthesis will be more reliable than a removable one because there will be less pulling and pushing of the implant during removal and placement if a removable is used. And some will also convince you that 4 is enough….all on four. But if you are placing minis for a removable prosthesis, then place 6 for balance, three on each side between the centrals to the premolars. Place the longest you can and bicortical if possible, because the maxillary bone is softer….and therefore more piling is needed….yeah…like building a house….see. Bone augmentation is unnecessary and very difficult, as is suggested by Dr Richard Hughes. To raise the height of the maxillary ridge, you will have to use a titanium mesh with bone graft mixed with bone marrow…..and it will take a much longer time, incur more pain to the mouth as well as th...
