Then, we use the MOSTDIMUM to make the composite BUD, around which we construct two composite laterals, giving this young man his first ever decent smile line which we hope will continue the process of transforming his life for the better. Wait till you see the final transformation!!!!!! After grafting the lateral labial surfaces, we place in the minis. Now, what do we do? We put in two implants for the laterals of course! What sort of dental implants? Ahhhhhhh......... Conventionals are out of the question. Minimized dental implants of course! Even then, we still had to graft the labial surfaces of the laterals to increase the thickness because there was only a wafer thin  layer of bone there...... having had no teeth there before at all.... congenitally missing. Here then is a classic case of minis being the treatment of choice! Open coil springs to upright the two peg shaped microdontic canines. Minis in the empty spaces to complete the case. Conventionals will require bone graf...

Notice the "CLEANING GROOVE"  between the two abutment holes. This is to facilitate the threading of a bridge cleaner and floss in between and thus the undersurface of the crown can be flossed right to the surface of the implants. The ability to floss thus and the smallness of the emergence margin of the mini will arguably prevent any peri-implantitis in the long run. In contrast, a conventional implant with an aesthetic emergence profile that includes a large emergence margin cannot be flossed all the way to the surface of the implant proper. The emergence profile emerges out of a volcanic-like crater in the gums. The surface of the crater is usually slightly inflamed and together with the large surface will arguably be more susceptible to peri-implantitis as compared to a mini dental implant. Examine the pics below. Let's continue with the replacement of the upper molar by copying the anatomical/biologically ergonomical/natural/no-brainer/obviously correct positions o...

K. F. Chow BDS., FDSRCS   November 16th, 2010 “Wolff’s law” states that bone models and remodels in response to the mechanical stresses it experiences so as to produce a minimal-weight structure that is ‘adapted’ to its applied stresses. The behaviour of bone according to Wolff’s law mirrors a fundamental trait of mother nature, i.e. optimal economic use of substance in the performance of a function. Thus to use a wide diameter implant because there is a wide hole seems to contradict this fundamental. A living organism deserves to be treated according to living rules of life, not static non-living engineering presumptions. Granted that we need to use a titanium screw, since the tooth germ implant is not yet available….. it does make more organic living sense to use the optimal titanium necessary to allow maximal living tissue around it and thus also minimize the perio pocket that inevitably forms around all dental implants. Minimized and optimized diameter implants should be the tr...

You can see and hear the lecture on the three critical margins of implant dentistry..... boring though !! http://www.youtube.com/watch?v=N1GF_82dY1g Every dental implant ever placed has created an iatrogenic  periodontal pocket. Yap! Has created a pathology in the mouth that has a certain amount of inflammatory infiltrate around it that ranges from a low grade perimucositis to a full fledged peri-implantitis. This fact does militate against  the use of large and extra-large diameter implants . The periodontal pocket that accompanies every dental implant we place is  a reality that every implant dentist must accept and manage as an acceptable evil for the sake of the greater benefit of being able to replace a lost tooth almost as good as before.  The issue at hand is what is the best approach to managing this compromise for the sake of the larger good. The best replacement for a lost tooth of course is another tooth, and that will likely come in the future in the f...

I think I am seeing things.........but my patient is not complaining and is happily biting away. The upper right did not have that much bone, so I did a sinus lift .....what. Hoping to develop and innovate to the point that I can use all minis and still lift the sinus ......or avoid it like some 3 rooted upper molars do....2 buccal roots in the buccal sinus wall and 1 palatal root in the sinus palatal wall.......what?!  You canna do that you....... well if He can, why not little me? Will keep ya allll posted. Oh, this guy did not wanna his lower right bridge yanked and thrown away. So we salvaged it with a mini right through the pontic. Told 'im that its temporary......but now its almost 3 years and he thinks its permanent. Anyways.... I never promised him its permanent!

Immediate extraction and implantation. Bone level is definitely higher than when the implant was first placed. Well what do you think? Nah........ can't be bone climbing up the implant. Its a camera trick! Whatever it is, I am really glad and I guess I will continue to do this "miracle" as long as the miracles keep coming and not run out. Not very scientific, but my patient is not complaining.

A case of immediate extraction and implantation, followed by PFM bridge within 3 weeks. Follow-up xrays showed healthy bone growing around the minis. Not only did the bone seem to have climbed up the second implant from the left, there is also a layer of healthy cortical bone around it and between the minis. There was a study that claimed that bone remodels around the minis at much higher rates than around a conventional, indicating the possibility that the bone around the mini maybe mainly woven bone and therefore not as good and sound as that around a conventional. Looking at this series of xrays, I am not sure that is true and if so, is it a disadvantage or advantage?  There is also the possibility that the bone that seemed to have climbed up the mini may not be in close intimate contact with the surface of the implant, and therefore may not be osseointegrated. Alright then, I am going to CBVT this one as soon as I think it is necessary enough to buy one.
