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...

Platform Switching and the Kai Foo's Three Critical Margins of Dental Implants

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 ...

NARROW DIAMETER DENTAL IMPLANTS

K. F. Chow BDS., FDSRCS  October 23rd, 2009 Narrow diameter dental implants are being increasingly used not only to stabilize dentures but also for long term applications like crowns and bridges. I agree with Carl in that there is no such thing as an absolute contraindication in medicine. Even botox which will kill you if injected into your bloodstream is used ingeniously and judiciously to extend the youthful looks of people. The key word is “judiciously”. Know your medicine well and know what you want to do with it and then you can apply it safely and usefully. It is significant that one of the doyens of implant dentistry has recognized that narrow diameters have their uses especially in narrow ridges and in suitable bone. I started out with conventionals and with the advent of minis, incorporated them into my treatment planning and in many complex cases have successfully integrated them both into my treatment planning taking into consideration the patient’s expectation...
