| 1. | Place two implants in the anterior mandible, #23 and #26 positions, under the incisors. Farther back and they become fulcrums and the denture rocks around them. |
| 2. | Locators can be processed in or picked up intraorally. It is recommended to pick up intraorally to compensate for tissue depression. |
| 3. | To connect the housings, place the white block out rings, hollow out the denture, then use self-cure resin or composite to lute the housings. |
| 4. | Replace the black processing insert with blue (light), orange (medium) or clear (heavy) retentive inserts. |
| 1. | Have more vertical play than locators. Can be used if implants farther apart than #23 and #26. Requires more vertical clearance than locators. |
| 2. | Process denture then place rubber dam to block out when curing in O-rings. |
| 3. | After O-rings processed, remove the O-rings and clean out the inside of the denture where the ball abutment made an impression. Relieve at least a millimeter so the denture doesn’t ride on the ball. If the housing is solid and not just a ring of metal, then vertical movement is already built in. |
| 1. | Useful if the implants are farther apart than the #23 and #26. Useful if an overdenture rocks around the locators. |
| 2. | Best retention and stability of any two implant attachment system. |
| 3. | Make an impression of either the implants or intermediate abutments. |
| 4. | After a wax try in completed, the bar is fabricated to fit under the proposed tooth positions. |
| 5. | If there is adequate vertical space then no reinforcing frame is needed. If there is limited interarch space a cast framework is recommended. |
| 6. | It is not recommended to refit a finished denture to bar retention. |
