Three implant abutments. These are called BUDs which stand forBridge Underpinning Device. Two of them are stainless steel buds and one is a composite bud.
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...
A direct impression was then made with a high quality precision type of alginate or silicone/rubber base material. The resulting models were then sent to the dental laboratory to construct the necessary three unit bridge 654 /. Alginate is more than adequate because we are not dealing with real teeth but implants and the accuracy obtained is adequate. A temporary bridge may or may not be placed since aesthetics is not a concern here. In this case, no temporary bridge was placed. The BUDs acted as comfort caps over the implants since they were designed to be rounded and smooth. Once the bridge was constructed, the patient was recalled and after testing in the mouth and adjusting the bite where necessary, the bridge was cemented over the BUDs with a suitable cement. In this case, glass ionomer was used. A temporary cement may be used for the sake of retrievability. Once the excess is removed, the crown and bridge is then...
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...
