Unknown implant: suggestions to remove attachment?

call implant direct and speak to Attachments International tech department. They will identify, and give you options for tools. implant rep

They look like you can grab them with a flat beak ortho pliers. A large hemostat might also work. There is no rule saying you have to use an internal wrench.

Ankylos implants, Syncone abutments. Contact Dentsply Sirona for product details or go to their website.

Sycone is a friction fit concept, so you don't want to damage the exterior of the abutment by using pliers; get the proper driver.

The implants are Ankylos..the abutment are Syncone. You must un screw each abutment ,and remember are Morse cone....you must release the lock nocking fron one side to othernuntil it loose

The abutments are then screwed into the implants using the 1.0 mm hexagon screwdriver. The torque- wrench with hex insert or a torque- controlled contra-angle handpiece serve this purpose. The recommended torque for the straining screw is 15 Ncm.

Increase retention? Did you try to replace the male component in the overdenture?

Ankylos implants with syncone abutments. Morse taper connection. No torque on those. Very unpredictable system! Good idea to change for locators !!

Those are Locator overdenture attachments made by Zest, they have a unique driver you can buy and use in ant latch torque wrench. The parts in the denture are the retentive elements that easily come out with the special removl tool.

Excellent system. Very predictable. Removable, implant retained and implant supported system. Why do you want to remove the abutments? Appears as if the denture cracked. Only problem in my opinion is planning. I use metal reinforcement on these, works like a charm. Trying to figure out how to restore this system with a removable BruxZir bridge, just haven't found the right lab yet. If indeed it is because the denture has a crack, I would suggest you remake denture with metal reinforcement and have lab repair current one so patient has a back up if necessary in the future. If opposing a removable denture, wear will be minimal over the years. If opposing natural dentition, will need to replace teeth every 5-7 years. Locators are an implant retained, tissue supported solution. If pt. was used to implant supported, they will not like Locators at all. Hope this helps.

Per my original post, these are Ankylos Syncone, not Locators, not F-Tx. The Scone concept is implant supported and therefore a rigid prosthesis is required as well as limiting cantilever length; it will function like a fixed bridge. Recommendation is that you leave the abutments in place (the driver spec given by mjs is correct) and fabricate a new prosthesis with a metal frame (per Eric); it can be chrome-cobalt so cost will be low. Order four new Syncone caps (retentive outer contour) and pick them up intra-orally after the prosthesis is processed; this prevents distortion during processing to influence the position the caps. If done properly, this system is superior to Locators when four implants are involved; Locators work best when there is only one axis of rotation or no rotation.

Yes for the person that said those are zest locators that is not correct. Zest locators are gold in color and do not look like that at all

how do you take an impression of the abutments? and then get a lab analogue. I have a similar case where the pt. lost the denture. the gold gaps can be picked up in the denture once it is made. I have made several of these over the years and find they give unpredictable retention and dont do it anymore.

Yes I am making a new denture for this patient at this present moment. Pt had zero retention with this system even before she broke the denture. Where does the retention come from with this system? Friction? With the new caps, you think there will be more retention?

The all acrylic overdenture shown with the crack and the four Locator housings and retentive nylon anchors will not work with these 'tapered' telescopic overdenture abutments. If another dentist made that for her recently, they did not know the abutment system the patient has in her mouth. The European concept of the milled telescopic overdenture abutment (male) and cast metal retentive 'overcoping' (female) system has been very successful but is hard to execute. European trained lab techs excel in casting and milling telescopic abutments. If done well, the removable overdenture is incredibly retentive. There is no splinted bar which improves hygiene and the notorious 'soft tissue creep' up and around the overdenture bar. The metal:metal wear is offset by the degree of taper at which the copings are milled. In practice, as both the male and female wear from frictional fit the retention remains consistent over the years. The concept is referred to as 'secondary splinting'. So with a given arch with 4 implants (minimum) and an implant fixture level impression the right technician can modify and cast UCLA style abutments for parallelism, mill them to a specific degree of taper. Next the lab can wax and cast the female retentive overcopings for each abutment. An overdenture metal framework is also fabricated - it can be noble metal or simply traditional Cr-Co removable framework metal. At the delivery appointment of the abutments the healing caps are removed and they are torqued to place, sealed and not removed from the mouth again. The overcopings are then seated on their respective abutments chairside. The cast arch framework is seated over the abutment complex and the roughened external surface of the overcoping is 'picked up' in the mouth with acrylic (like ProTech or Parkell's Acrylic Solder) to the cast metal framework. At the end of this visit a pick-up impression is made to make a 'working model' to take the case to completion. At the lab bench GC pattern resin dies are made to the lubricated intaglia of the female overcopings and the impression is poured in stone. A wax rim is added to the frame and attached overcopings and at the next visit jaw relation records are made to take the prosthesis to wax try-in and eventual opaquing and acrylic processing/delivery. The lab, metal and componentry bills are significant. Thus, the case fee is commensurately much higher. But, let me tell you - the retention is phenomenal and the patients become serious fans of your practice. Don't get me wrong - I absolutely swear by the Locator system which is far less expensive to both the doctor and patient. However, some patients stretch and wear the Locator nylons too easily and become frustrated with the frequency with which they have to pay for replacement gaskets. Fortunately, this is rare, but as a Prosthodontist I run into it. Without exception every implant overdenture case should include a cast metal framework - maxillary or mandibular. To not incorporate this into the case begs for breakage and dissatisfied patients. I surgically placed Ankylos implants for awhile and I am a fan. I knew of the Syncone system but did not have occasion to use it, but it is the telescopic/Conus crown concept simplified with prefab abutments of varying angles and pre-made female overcopings. I would reach out to your local Dentsply/Ankylos rep with componentry questions if you want to work with the existing abutments. Go to this site and it will show you the technique for the Syncone system. http://www.dentsplyimplants.com/en/Digital-solutions/ATLANTIS-Abutments/~/media/D0B2FEF20FD04174ACD68B1B26AF203A.ashx
