Effect of Implant Position on Clinical and Radiographic Outcomes of Locator‐Retained Mandibular Overdentures: A 1‐Year Prospective Study

Abstract

Within the limits of this short-term clinical study, canine position for implants retaining mandibular overdentures with Locator attachments is preferred over the first premolar position, as it was associated with reduced peri-implant pocket depth and marginal bone loss after 1 year.

Evaluation of volumetric wear of abutments on the retention loss of ball attachment systems in implant‐retained overdentures: An in vitro study

“…30,35 For implant overdentures, no certain value has been reported as far as we know. For removable dentures, patient satisfaction has been reported to be supplied by an 8-20 N minimal amount of retention.…”

“…For removable dentures, patient satisfaction has been reported to be supplied by an 8-20 N minimal amount of retention. 30,35 For implant overdentures, no certain value has been reported as far as we know. Furthermore, the findings of a recent retrospective study showed that momentary retention forces of implant overdentures affect quality of life, but not patient satisfaction and it was pointed out that initial retention has more impact on satisfaction rather than the retention afterwards.…”

“…All the tested groups showed significant differences in volumetric wear after 5000 insertion-removal cycles that simulated~4.5 years of clinical use. 30 Positioning the implants more anteriorly has been shown to reduce the peri-implant bone stresses in a finite element study. [26][27][28][29] In a recent clinical study, it has been publicized that the canine area preserves the peri-implant bone better than the premolar area in two implant overdentures.…”

“…[26][27][28][29] In a recent clinical study, it has been publicized that the canine area preserves the peri-implant bone better than the premolar area in two implant overdentures. 30 Positioning the implants more anteriorly has been shown to reduce the peri-implant bone stresses in a finite element study. 26 Moreover, it has been presented that the insertion of implants in the lateral incisor area provides a mechanical advantage for overdenture support.…”

Displacement of Customized Abutments Designed on a Working Cast and in the Oral Cavity: A Comparative In Vivo Study

“…Implant therapy is effective and convenient for restoring missing teeth . However, since bone defects vary between patients, the implants may deviate from their ideal position or may not show the ideal inclinations . Although the stock abutments can be quickly and easily applied to the patient, the shape of the abutment can be slightly modified as needed if the implant is not in the ideal position .…”
