Marginal bone loss and associated factors in immediate dental implants: a retrospective clinical study.
Article in International journal of implant dentistry, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
purposeThe aim of this study was to evaluate the marginal bone loss (MBL) over a follow-up period of up to 36 months in Immediate dental implants (IDIs), as well as the impact of various clinical variables on the MBL.
methodsIDIs placed in two surgical phases were evaluated. Implants were classified into bone loss (BL, exposed threads), bone remodeling (BR, crestal bone at the implant margin ± 0.1 mm), and bone overlapping (BO, bone above the abutment).
resultsA total of 1,040 IDIs were inserted in 344 patients with a successful osseointegration rate of 98.9%. The average MBL at 2, 6, 12, 24, and 36 months was - 0.3 ± - 1.0 mm, - 1.1 ± -1.8 mm, - 1.4 ± - 1.8 mm, - 1.7 ± - 1.9 mm, and - 1.3 ± - 2.3 mm, respectively. In the Baseline-12-month period, 17.5% of the IDIs presented BL, 9% BR, and 73.5% BO. For the B1-12 month period, 19.8% presented BL, 10.7% BR, and 69.5% BO. Mixed regression models showed significant MBL overtime pre-loading (p < 0.0001), stabilizing at 8.5 months from implantation. Immediate mandibular implants had lower MBL (p = 0.0365). Post-loading, MBL was lower in the mandible (p = 0.0095) and positively influenced by abutment height and rotational abutments.
conclusionsThe present study supports the clinical efficacy of the IDIs placement protocol with high survival rates and acceptable MBL. It is recommended to place bone level implants slightly below the crest to ensure the platform remains at an optimal depth during the initial bone remodeling phase post-implantation.
