The implant supported dentures can be classified as follows; depending on the connection type:
The most economical solution in implant-supported dentures are Ball-Attachment Dentures . In the lower jaw during chewing and speech, especially in lateral movement provided an effective stability with two implants.
Implant supported bar connections, especially 4 implant support in both the upper and lower jaw provides lateral very effective stability with both vertical and lateral movements. Implants acts by supporting each other. Therefore, excessive stress does not occur on implants during use and rapid bone loss in thin parts of bone is not encountered.
Locator attachments are newer , healthy and useful attachments according to ball and bar attachments. They can be used with 2,3 or 4 implant supports. Because of the attachment?s proper distribution of forces during chewing function , excessive stress does not occur during use on implants. In addition, maintenance and cleaning is easy. In cases where there is insufficient bone tissue, they are more healthy for supporting implants.
Locator attachments on bars have all the advantages of the locator attachments. But production time is a little longer and complicated. Furthermore, the use interdental brushes for cleaning is important.They can be used in order to produce a solution when the implants can not be placed in desired locations due to defects and limitations in jaw bone.
