Survival rate of immediate functionally loaded ball-attachment mini-implants retaining mandibular overdentures: A systematic review.
Synthesis in Journal of Indian Prosthodontic Society, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
aimImmediate loading protocols are frequently applied when placing mini-implants (MIs), although many of these may not be functional loading. Data on immediately functionally loaded MIs are limited. Therefore, this systematic review aimed to answer the question: What is the survival rate (SR) of immediately functionally loaded MIs placed in the edentulous mandible to retain a complete mandibular overdenture? SETTINGS AND
designStudies published in peer-reviewed journals up to April 2025 were considered. MATERIAL AND
methodsAn electronic search was conducted using MeSH terms and free-text search in April 2025 across Web of Science, PubMed, Cochrane Central, EBSCOhost, and ScienceDirect. Eligible criteria included case-control studies, retrospective and prospective case series, cohort studies, clinical trials, and randomized controlled trials. STATISTICAL ANALYSIS USED: Not applicable.
resultsOut of 1854 identified references, seven studies met the inclusion criteria, three randomized controlled and four prospective case series. A total of 496 immediately functionally loaded MIs were placed in 124 patients. The diameters of MIs were 1.8, 2.0, 2.1, 2.2, and 2.4 mm. Within the 1st year, 16 out of 495 MIs failed, resulting in a 1-year SR of 96.77%. A 24-month SR of 94.4% was reported by three studies, and a 36-month rate of 94.77% was reported by two studies.
conclusionsCurrent evidence indicates that immediately functionally loaded MIs are a promising option for retaining mandibular overdentures, with a high 1-year SR of 96.77%. However, the limited number of included studies and relatively short follow-up periods highlight the need for further well-designed, long-term research to validate these findings.
