Comparison of marginal bone loss in implant supported over dentures in early loading

Abstract

Aim: The purpose of the present research was to evaluate the marginal bone loss in implant supported over-dentures in case of early loading on denture. Methodology: 36 edentulous participants (mean age 68 years, SD 9.2) were randomly assigned into three treatment groups (n¼12). A single implant was placed in the mandibular midline of participants to support an overdenture using a 6-week loading protocol. The control group received Southern regular implants and standard ball attachments. One group received Southern 8-mm-wide implants and large ball attachments. Another group received Neoss regular implants and Locator attachments. SPSS was used to determine between groups differences in marginal bone loss, implant stability, implant, and prosthodontic success (P<0.05). Results: Implant success after 1 year was 75% for Southern regular implant (control) group; and 100% for the Southern wide and Neoss regular implant groups (P¼0.038). Prosthodontic success was comparable between the groups but the maintenance (41 events overall, mean 1.2) was greater for the Locator and the standard ball attachments. Conclusion: Mandibular single-implant overdentures are a successful treatment option for older edentulous adults with early loading protocol using implants of different diameters and with different attachment systems.
