LOCATOR STRAUMANN PDF

Ian Braby says: Yes — retentive anchors are not the only choice for overdenture retention with the Straumann System. Yes, parallelism counts. I have used the Straumann Dalla bona style round ball abutment with success over the years and used their blue plastic handled lamellae tightener as needed for the matrices to be tightened in the overdenture on recall. Lab processing can be done with analogs. I prefer chairside attachment with a conservative amount of pick-up acrylic.

Lab processing can be done with analogs. I prefer chairside attachment with a conservative amount of pick-up acrylic. Unfortunately they were only designed for use with their 3. In my experience they do not readily pivot and a periodic o-ring change keeps patients more than satisfied.

ERAs are another popular option — in my hands they do not perform as well and require more maintenance. The Locator system is superior in: its design tipped hat to Dr. Bob Vogel ; less rotation around a fulcrum even if there are only 2 implants; and infrequent patient returns with loosening overdentures. With many retentive color choices in the nylon replacements you can meet the whims of weak patients who need their overdenture easier to remove blue and those patients who never feel like they are tight enough clear.

Of course, your mileage may vary.

Such implant-supported prostheses represent a compromise solution between the advantages of fixed prostheses and traditional complete removable dentures in totally edentulous patients. In scientific literature good adaptability was reported in edentulous patients provided with maxillary complete removable dentures, whereas phonetic and functional problems due to prosthesis instability were lamented by patients wearing mandibular complete removable dentures. As to implant-supported OVDs, several advantages were pointed out just like improvement of chewing ability in comparison with traditional complete removable dentures, esthetic and phonetic improvements, lower susceptibility of the success of the rehabilitation to the optimal insertion of implants than fixed prostheses. Notwithstanding the mandibular residual ridge resorption, a sufficient amount of bone tissue often remains in the interforaminal region to properly insert at least 2 implants. The presence of 2 or 4 osseointegrated implants in such area seems not to affect the long term success of OVDs: as to retention, stability, stress distribution and peri-implant health, comparable results were noticed with both 2 or 4 interforaminal implants. As to the supporting implant system, several studies obtained comparable results with both submerged and non-submerged implants.

The transmucosal height of the abutment may vary from 1 to 4 mm, 1 to 5 mm, 1 to 6 mm, according to the system of implants used. If the height is chosen precisely, the biomechanical conditions are favorable, thanks to a point of force application close to the platform of the implant. So, it is very important to measure the maximum height existing between the platform of the implant and the mucosal edge to let emerge only 1. A combination of inside and outside retention ensures the longest lasting performance25 Fig 8. Ref 25 — a non-rigid connection to the implant: the replacement male is in static contact with the abutment, while the titanium cap in the resin of the prosthetic base allows a rotational movement, absorbing then the forces stresses without any resulting loss of retention21, Fig 7: Lowest profile 3. Ref: 25 Fig 8: Self alignment or dual internal retention.
