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...
K. F. Chow BDS., FDSRCS May 20th, 2010 The term “platform switching” may be a misnomer. Misnomer means using the wrong word to describe something. The platform that we are referring to is the round surface area on top of the fixture in which the screw hole for the abutment is located. Branemark set the trend by making sure that the abutment fits exactly over the top-surface of fixture, with the periphery flush with each other……which is a logical decision at the time….and everyone copied him…….which always resulted in a “normal” resorption of the bone away from the junction. The advantage of “platform switching” was discovered when a dentist did not have the right sized abutment to fit flush with the fixture and inserted an abutment whose circumference/undersurface area was smaller than the platform/topsurface area of the fixture. This happily and unintentionally took the junction/microgap/microorganisms away from the bone and thus to the pleasant astonishment of the dentist after ...
We placed in the upper anterior implants carefully and everything healed uneventfully. However, when the patient returned, he insisted that we remove them, the reason being that, "He just could not accept them as part of his mouth and body!" This was a realization that he had only after he had the implants placed. After numerous attempts to persuade him otherwise, we finally accepted the fact that the patient for some reason beyond us, cannot accept the dental implants as part of his mouth and body. By then, the implants were fully osseointegrated and ready for harvesting and prosthodontics. So near, yet so far!!!! Rest assured, we tried our level utmost to convince the patient how simple the prosthodontics were and how much he already paid and what a boon a set of fixed teeth as compared to his dentures were. With all the preliminary exercises in persuasion and explainations done conscientiously, we got the patient to sign a carefully worded consent form indemnifying us fr...
