Fractured Screw Removal Kit for Fractured 3.3mm diameter Legacy 3 Implant Direct?

I have unfortunately fractured a screw in a 3.3mm diameter Legacy 3 Implant Direct implant. I have tried the ultrasonic scaler and it didn’t work. I was wondering if anyone is aware of a screw retrieval kit. The NeoBiotech kit I am told cannot work as the screw diameter is 1.2mm. Any suggestion would be welcome including comments on predictability of cementing the abutment with Panavia as in Tatum implants?

Are you sure it's 3.3mm? Look on Implant Direct's website and didn't see that diameter listed (see here: http://www.implantdirect.com/legacy3). Anyway, DDSGadget.com has an Fractured Screw Removal Kit that works with Legacy Direct. Only issue is that the kit will only work with implants that are 3.5mm in diameter or greater. Hope that helps.

Your posting comes at an interesting time of the year....... for people of the Jewish Faith....Passover is 10 days away.....for those of you who are not familiar with the story, it is the story of Moses leading the Jews out of Egypt...walking through the Sinai Desert to get to the land of Israel. During this 40 year journey, Moses climbed Mount Sinai where God came him the Ten Commandments, often shown in illustrations as two stone plaques....... So to relate this story to modern times, the Legacy 3 is manufactured by Implant Direct, and why not ask God himself how to remove the implant......in this case God's name is Dr. Gerald Niznick, and if you refer to him as God, he will not be offended........ Dr. Niznick is the creator of Legacy 3 and Implant Direct......he will give you the best answer...... or knowing him as I do, he will personally show up in your office and take it out himself!!

oh, I love it! So true. Way to go Dr. Rudick! Nobel has a screw removal tip for a 3.0mm implant. It's an RA latch type that can fit into a handle. Don't use it in your handpiece.

Dr. Rudick- your answer is hysterical. Implant Direct was bought by Danaher, which also owns Nobel, so it is under different management. They probably also believe they are God like too. There is a screw removal bit that I can email you it is around $80 and designed to get the screw out. I can email you a picture and how to use it since I cannot post a picture here. keith@dess-usa.com www.dess-usa.com 8553377872

I took one out one time with my microscope and some canine length endo files. You cut try cutting a tiny mesiodistal groove then use thinned down square ortho wire bent in a tee shape like a screw driver. YouTube some of Dr. Gerard Cuomo stuff. Best of luck.

i believe implantdirect makes a screw removal bit; actually i know they do because i have one; just call them; they will get the part number for you; btw, dr rudick, when niznick was still at the helm of id, i had a problem and emailed him at the suggestion of one of the customer service reps ... and he responded within 20 minutes .. after 9 p.m.; took care of business; what a guy; so unlike most of the other dental related companies out there who just throw a bunch "if, ands, and buts" at me instead of caring about actually addressing the issue; although i will say i had a good response from tom stratton when i had a problem with a particular surgical guide software that they were promoting ... although the head of that company refused to even acknowledge the issue; oh well.

A broken screw is not usually an easy thing to remove and it becomes more difficult depending on the submergence of the implant and the access location and the line of sight and even worse if there is bleeding from the surrounding tissue. There are a couple of kits available that in principle sound great (NeoBiotech Screw Removal Kit is one). These kits work by using a guided drill to penetrate into the screw and then using a reverse drill to engage the drill hole in the screw. Problem is that the drills cannot pierce the screw if it is titanium alloy which is what Implant Direct and many other manufacturers use. The kits may work on a softer metal such as a gold screw but I have never been able to make this system work on an Implant Direct screw. The option of last resort is to cut off the end of a dental hand instrument and create a sharp flat screw driver edge which will fit into the access hole and which may engage the screw. If not then you will have to cut a slot into the face of the broken screw for a positive engagement. This technique will work but often takes a lot of time fussing. Care in cutting the slot is crucial that the treads of the implant are not damaged. Once out, an assessment needs to be made as to the reason the screw fractured and modify the loading on the crown system before replacing the screw. Good Luck!

never put a rotary instrument inside an implant! There's no way on this planet you can cut a slot into a tiny little retaining screw without damaging the threads. The lease little movement of your hand or the patient will cause the bur to ding up the threads then you're done. Use the Nobel screw removal tool. It's inexpensive and works great. Many times I can remove a screw fragment through a small tissue access. Bleeding doesn't matter, once you've removed a fragment or two you don't even need to see to remove it. You can feel it coming out. Once the piece is out of the implant, blow air/water down the access hole to flush it out. If it isn't quite loose yet, you the cotton end of a cotton tipped applicator to engage the fragment and use it as a make shift screwdriver to get the last thread or two to disengage. I have slotted abutment screws to try and remove them but it's only a last resort when the only other option is removing the implant. So if I ding up the threads, well, the implant was coming out anyway.
