3-27-13 UPDATE ..... It has been many years since I have visited let alone updated this site .... ALL OUR IMPLANTS ARE DOING FANTASTIC ... No failures so far ... (knock on wood) I still use only custom hand waxed and cast HIGH NOBLE GOLD on both our abutment crown that screws down into the analog that has had plenty of time to heal down inside the bone. And the finished crown that is cemented over the abutment crown that has the screw torqued into place thru the top of the abutment crown. The word Noble in metal means the least reactive ... the least allergenic material there is period! And coming up out of the bone and tissue I think this is VERY IMPORTANT! It does cost more ... But we have never done a case without it! I also have all our abutment crowns (and finished crowns) custom hand waxed and cast to fit exactly each individual case the best way possible. We do more and more implants all the time ... I know I require a long healing time, but refuse to change what works! ... I never EVER change a procedure because it's faster or less costly to do ... You only change a procedure because it's BETTER!

We haven't used these old spline implants pictured here above for years now ... All Noble Biocare for now ... But all our old splines implants are doing fine too. ... But I am still using those photos as they still shows the basic idea ...

2001 ... The age of the implant is really here for sure now. The latest implants have the superstructure screwed in and the crowns cemented over them. The screw head is not going through the outside of the crown and being pounded on by the opposing dentition and loosened. The newer implants also have a 1.5mm internal hex, triangle, splines, etc for the superstructure to sit on or inside instead of the old 1/2 mm raised hex . If the implant crown loosened even a little bit it could easily round off the corners ruining the implant in the bone, necessitating surgical removal. And now these new internal tapered screw vents support even better ... and lock in kind of like how a fishing pole goes together ... one telescoping into the other .. even more support that the splines.

I am going to show a case we just placed yesterday (2001) further down on this page. We used David at Sun Labs in Eureka, CA. 530 246-7600. Sun labs specializes in only implant lab work. They ship nation wide. David will rent all the instruments, torque wrenches, etc. and sell any brand implant one might like to try out so you don't have to buy a different set up each time. They also use binocular microscopes for that great fit.
We use high noble Gold on everything where cast metal is required but I think it is most important when used below tissue. The case shown further down the page was done in Ivoclar (softer porcelain) and high noble Gold.

We start a possible implant with a consult with the oral surgeon for a 3D Tomograph, etc. to see if they are a candidate for an implant. Enough bone, grafting, patient health, etc. If all is well we start with a surgical template or stent made of clear plastic that snaps over the existing ridge and teeth to aid the oral surgeon in placing the implants in the ideal angles and position.... The photo above shows the instructions to the oral surgeon to consider for the implant and the photo just below this shows what a clear surgical template looks like. Getting the post in at the spot, the right angle and in enough bone is the surgical goal! Why take a chance without a template?
We leave the surgical post in the bone to heal in the lower jaw for 5-6 months before we build the new crown on it and leave it to heal in the upper jaw for at least 9 months because the bone there is more porous. I know this is longer than many dentists allow .... but having been in the trenches for so many years and having waited for such predictable implants like we have now and seeing over the years that the ones that were left in the longest before loading held up the best .... "I will not load an implant before it's time"!

We have been doing more multiple implants lately ... everything is working great!

Gingival Cuff

As previously mentioned, at the 1st consultation appointment with a 3D Tomograph Xray the oral surgeon will determine if there is enough bone for an implant and whether some bone grafting might be required. On the surgery appointment he will place the implant(s) into the bone, using a template or stent the dentist doing the case will provide as a guide so the posts are put in at as ideal an angle as possible and the bone mass allows. He will at the same time place a thin metal healing cap allowing the gum tissue to heal in above it keeping all bacteria, etc. away from it as it heals (think about it .. this is even a common sense thing!) And, about 6 weeks before the implant is ready to start impressions for the crown I have him surgically expose and replace the healing cap with a taller gingival cuff so we can access the implant for our crown to follow.
It is best to let the implant heal in the lower jaw for 5-6 months and 8-9 months in the upper jaw, because the bone is much less dense there..
The first thing your dentist will then do after healing, is remove the gingival cuff (shown above) with the hex wrench shown above (#3). He will then put the retaining screw into the implant post, (#1) and snug it down into the implant where the healing cap was. Take an xray to be sure it is seated all the way. Place a little cotton or foam into the top of the post so no impression material gets in there. Then he will take an impression of your whole arch. We make a custom tray, but you must make allowance for 18 mm of clearance for the length of the impression post.
After the impression is taken the implant post is unscrewed and the post with the screw in it is snapped into the impression .. it has angled flat sides to seat in the impression perfectly. The analog part (#2) that goes into the lab plaster model is screwed onto protruding screw at the bottom of the implant post and poured up. This then 100% duplicates what you the patient has in your mouth. Your dentist will then with tight finger pressure reseat the gingival cuff until the lab can deliver your new crown or you mill it out with you Cerec machine!

On your appointment to place your implant crown your dentist will first, again, remove the gingival cuff. He will then place the recessed post screw (#3) down into the crown post (#4) and then screw the post into the implant (shown on model #6). This is then torqued into place with the hex drive insert (#2) that is placed into the torque wrench (#1). Each implant brand has it's own torque wrench with it's own setting.

David at Sun Labs makes the above pictured key that shows us that the implant is seated down in the right position. It also insures that the crown post is seated all the way, as the key is made to fit perfectly over the top edge of the post. after trying on the crown and checking the bite, if all is well, the post is torqued into place.

A small cotton pellet is placed in the top of the post so none of the cement we glue these implant crowns on with gets down in the recessed part of the post, in case we ever have to remove it again later.

The finished crown in place, nice gingival papilla
Looks like the rest of the natural teeth
It is important to check the bite on these about
every 3 months or so the first 1 - 2 years to keep the lateral forces controlled.

There are no guarantees with any implant, but they are becoming much more predictable, especially if the stents or templates are used during surgery and you have an oral surgeon or periodontist place them that does them routinely. ....And as already mentioned several times ... I also think it is very important that the standard implants are left in the bone for plenty of time to really osteointegrate as much as possible before loading them!. We usually wait 6 months on lower teeth and 8-10 months on upper teeth (the bone is less dense on the upper teeth). We know how predictable these long time healing implants are and they keep the bone from resorbing! The immediate loading ones might be okay, but it will take 10 -12 years to really find out.

One last thing .... I never pressure anyone into an implant ... We explain all the options first .... Plus ... If a patient is doing just fine with their existing partial or what ever .... Why not leave things alone? Why even risk a possible complication not to mention all the costs involved. These patients need not be coerced into implants.
