Mandibular Overdentures Retained by Two Mini‐Implants: A Seven‐Year Retention and Satisfaction Study

Abstract

In this limited sample size clinical study the results indicated that after connecting mandibular overdentures to two mini-implants, patient satisfaction significantly increased and retention significantly improved during the 7-year observation period.

Mini‐implants and narrow diameter implants as mandibular overdenture retainers: A systematic review and meta‐analysis of clinical and radiographic outcomes

“…The selected studies were divided into two groups, one with studies using MI (n = 24) and another using NDI (n = 12). The MI group consists of 1 cross‐sectional clinical study, three retrospective longitudinal clinical studies, 13 prospective longitudinal clinical studies and seven randomised clinical trials . Eight studies used conventional loading, 13 used immediate loading, two studies used both loading types, and one study did not report this information .…”

Eight studies used conventional loading, 13 used immediate loading, two studies used both loading types, and one study did not report this information . One study used bar attachments, one study locator attachments, 19 studies used ball attachments, and three studies used bar and ball attachments .…”

“…The NDI group comprises three retrospective longitudinal clinical studies, six prospective longitudinal clinical studies and three randomised clinical trials . The follow‐up time of the MI studies varied from 1 day to 7 years, while the follow‐up of NDI studies varied from 3 months to 10 years . Ten studies used conventional loading, 1 study used immediate loading, and one study did not report this information .…”

“…The methodological quality of the studies was evaluated and classified separately, and the results are listed in Table . Of the 24 MI studies, 12 were classified as poor, 10 as fair and two were classified as good . Of the 12 NDI studies, two were classified as poor, seven were classified as fair, and three were classified as good .…”
