Followup observation, filmed X-ray and inspected oral regularly to observe the bone resorption of peri-implant and the conditions of soft tissue, and then analyzed complications. Results: during observation, no implant was failed, 26 implants had no obvious resorption of the marginal bone, 2 implants had peri-implant mucositis, 2 retentive force of dentures were decreased which were increased after changed the locator retentive inner liner. Conclusions: the clinical effects of locator implant overdenture is reliable, and it can improve the life quality of the elder patients who have edentulous jaw.
