Clinical application of an implant as well as a prosthetic appliance with conventional denture is being established in patients with loss of multiple mandibular. Teeth there are two applications which are a method with bone-anchored bridge and another method with overdenture by supporting with a few number of implants.
The comparison among various attachments used for overdenture by supporting with a small number of implants are conducted and some findings are reported.
Questionnaires presented to the members of this study group included the following.
1. The distribution of age and sexuality of patients
2. The kinds and types of attachments (bar attachment, conus crowns, magnetic attachment, O-ring,etc.), and the frequency of use
3. The results with age of each attachment
4. The contents of the trouble cases in each attachment
5. The prognostic results by the relationship of occlusion in each attachment
6. The results by the supporting style of a bar attachment
These subjects were mainly studied by using long-term patients as controls,and preferable methods were discussed.
Long-term persistence of mandibular overdenture was highly observed even if it was supported with a small number of implants, suggesting an effective method with high predictability.
