Extra Wide Implants for Immediate Placement: Any Experience with These? | OsseoNews Discussions on Dental Implants : "* December 15th, 2009 Dear osurg, “Iatrogenic”, according to Webster’s is defined as, “induced inadvertently by a physician”. When we insert a dental implant into the bone and gums, we create a pocket around the neck of the implant as it traverses through the gum and into the oral cavity. This pocket is different from the normal gingival sulcus that is found around a normal tooth. When the gingival sulcus become diseased due to infection, trauma or abnormal immune response……it becomes inflamed and deeper and the diseased state is then called a pocket. I call the corresponding sulcus around the dental implant as it emerges into the mouth a pocket because it is not normal but a pathology. In this case the pathology is physician-induced and therefore iatrogenic! If we examine the pocket around the implant histologically, it is a vast difference from that of

Extra Wide Implants for Immediate Placement: Any Experience with These? | OsseoNews Discussions on Dental Implants : "K. F. Chow BDS., FDSRCS November 28th, 2009 I agree with Professor Tarek from that ancient city of knowledge, Alexandria. Its got the largest library in the ancient world. His approach is very sensible because it allows the bone and mucosa to heal and any infection to disappear. A 3.5mm diameter implant is reasonable as it allows plenty of marginal bone around it. I believe that the learned Professor will place implants that are at least 10mm long or more, based on the quality and quantity of the bone available. The assumption that the fixtures used should at least match the size of the roots of the teeth that it is replacing is fallacious or to say it simply, incorrect. The natural tooth is attached to the bone via a highly sophisticated biological structure called the periodontal apparatus. The dental implant is attached via osseointegration, a form of ank

K. F. Chow BDS., FDSRCS   April 6th, 2010 Many of my complex cases are treatment planned with both narrow diameter and regular diameter dental implants. My experience in cases when I use only narrow diameter is that I complete my cases much faster than when it involves regular diameters. As such, it behoves serious practitioners to keep both types in mind when treatment planning because I forsee that we are beginning to shift towards a more balanced and sensible approach rather than a prejudiced and narrow approach. Cheers! Richard Hughes, DDS, FAAID, FAAIP, DABOI   April 7th, 2010 Dr. Chow: I agree. sergio  April 7th, 2010 Couldn’t agree with you more, Dr.Chow.

Yes. They are mini dental implants . The anterior implant has a composite bud light-cured on. The posterior 2 implants have metal buds cemented on. A direct impression was taken and sent to the lab where the bridge is made the usual way in which conventional crowns and bridges are made but designed to provide a friendly interface with the gums and easy maintenance. With the increasing use of dental implants, the dentist has become more and more lab-dependent to the extent that he/she often seem just like a technician. All the dentist have to do is to send the models and X-ray images to the laboratory and back comes a precision-stent together with the prefabricated crown or bridge. The dentist places the stent, drills the hole and screws in the implant to a preset depth and then cements the crown or bridge. Simple and straightforward but highly lab-dependent and turns the dentist from a clinician into a technician . The bud and direct impression approach gives back the dentist the re

One of the most beautiful image of a dragonfly that I ever captured in my garden. Everytime I look at it, I am reminded how crude our imitations of mother nature is. And also what a pathetic imitation our dental implants are compared to the real thing.

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

Ken Clifford, DDS   October 24th, 2009 Dr Chow - Amen to all your comments. There is absolutely no reason not to use mini implants. I have been cementing full arch mini implant hybrid bridges as a denture alternative for the past two years. My opinion is that a CEMENTED bridge on mini implants is an affordable alternative for patients unwilling or unable to pay for the all on four bridges, or the conventional implant porcelain/metal solutions. Cementation to minis eliminates the micromovement responsible for most implant failure in a full arch situation. By using quality denture teeth and a quality denture acrylic with high flexural strength, I can quickly construct a highly aesthetic denture alternative which can be loaded immediately. Patients go home happy, and so do I! Paresh B Patel   October 27th, 2009 Dr. Chow, thank you for your well organized and eloquently articulated thoughts on the current state of mini implants. I look forward to reviewing your text “Mini

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 expectations an

K. F. Chow BDS., FDSRCS   November 13th, 2009 Thanks for the kind words guys. While I am yet feeling elated and therefore a little brash, let me push the debate a little further. We all know that the transmucosal passage of the dental implant when compared to the transmucosal passage of an actual, real, original living tooth is actually a pathetic imitation of the real thing. The real thing has a nice epithelial attachment with a nice drain around the tooth constantly flushed with antibacterial substances and prohealth nutrients for the gingivae. Not only that the gingival cuff has circular fibres, connective tissue to tooth fibres, bone to tooth fibres , connective tissue to bone fibres etc. that gives each tooth a nice firm resilient yet elastic cuff around the it. Go review your periodontology texts and see for yourself. The dental implant has only a pseudo epithelial attachment and a few if any specialised soft tissue fibres and at best is actually an iatrogenic and pat

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

A PROSTHODONTIC SOLUTION FOR THE MINI DENTAL IMPLANT As a result of the current less than satisfactory prosthodontic solutions for the mini dental implants, a new solution has been developed. This method is called the “BUDDY METHOD” and is described as follows for replacing the right upper premolars and first molar. It can also be used in all parts of the mouth. The method is described as follows:- Mini dental implants were inserted parallel to each other with 4mm sticking above the gums. This will include the O-ball head and neck with about 0.5 to 1.0mm of the collar sticking above the gum. Minis from Imtec or Intralock or others of similar design can be used. The BUDs{Bridge Underpinning Devices} were snapped onto the 56 / mini dental implants. The snap-on and snap-off function is simple, repeatable, precise and lends itself to impression taking without easily coming loose or shifting. They are checked to make sure the base of the BUDs ar

      2. IMPRESSION AND ANALOGUE METHOD A more elegant technique developed with the use of an impression coping on the mini implant head. The coping came off with the impression and then analogues were fitted into the impression copings before pouring the cast models. The crowns and bridges were then built overt these analogues or over the copings which were then incorporated into the prosthesis. A recurring problem with this technique is the tendency of the impression copings to shift or come loose during the impression taking, resulting in inaccuracies. 3. COMPOSITE/GLASS IONOMER/CEMENT BUILDUP METHOD A sticky material like composite, glass ionomer or a dental cement can be applied on to the mini implant head. The implant head should be etched beforehand with an acid similar to the one used to etch porcelain. Once set, the build-up can be trimmed into the shape of an abutment. A direct impression can be taken for crown and bridge construction in the laboratory. The d

THE CURRENT CHALLENGE IN MINI DENTAL IMPLANT TREATMENT When minis were first used to carry crowns and bridges, the main problems were that the heads of the minis were too small to lend themselves for impression taking and difficult prosthodontic construction of crowns and bridges in the laboratory. When cast, the heads would fracture off easily. Several methods have been devised to overcome this problem:- FILL UP WITH CEMENT METHOD The lab technicians simply built up the fractured heads of the minis and then constructed the crown or bridge on top of them.  Because of the small diameter of the mini dental implant, the resulting crown always have a base that rests on the mucosa immediately surrounding the emerging implant. This overlapping of the crowns and bridges on the mucosa is universal when restoring mini dental implants. The crowns and bridges were cemented into the patient’s mouth. Whatever gaps present between the crowns and the mini heads were filled up generous
