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:-

  1. 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 generously with cement. The excess were then removed from around the periphery of the crowns and bridges. These always resulted in a circular margin of cement in direct contact with the mucosa. This direct long term contact of cement to mucosa were assumed to be acceptable and unlikely to cause long term complications. Todd Shatkin’s “FIRST Technique” is basically of this nature and thankfully so far has given little or no problems since it was first used about ten years ago.

FIRST stands for Fabricated Implant Restoration Surgical Technique. This is a highly lab-dependent technique outlined as follows :-

  • X-rays and models are sent to a FIRST Laboratory.
  • A precision made surgical stent is made that will determine precisely the number and position of each mini dental implant to be placed. Even the depth to which each implant is placed is determined by the titanium sleeve that is incorporated into the surgical stent.
  • The final crown and bridge is prefabricated in the FIRST Lab and sent to the dentist together with the surgical stent.
  • All the dentist has to do is to place in the surgical stent and drill the prescribed holes to the exact depth required, all guided precisely by the surgical stent.
  • The mini dental implants are then screwed in to the exact depth as indicated by the titanium sleeves built into the stent.
  • The crown or bridge is tested in the mouth and then filled with a resin cement and cemented into place. All excess cement is removed and the treatment is complete.

NARROW DIAMETER DENTAL IMPLANTS: POSTED IN OSSEONEWS

K. F. Chow BDS., FDSRCS   says: October 23, 2009 at 11:26 am THE CASE FOR NARROW DIAMETERS/MINIS/REDUCED DIAMETERS/ MINIMIZED DENTAL IMPLANTS/MOSTDIS 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 integra

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

NARROW DIAMETER DENTAL IMPLANTS

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
