Split Crest-Is It Necessary to Fill the Gap?-A Controlled Trial.
Article in Journal of functional biomaterials, 2025. 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
introductionThe split crest (SC) is a technique for horizontal ridge augmentation that enables simultaneous implant placement. While the use of bone grafts within the osteotomy gap is well-documented, the efficacy of dentin as a graft material in SC procedures has not been thoroughly evaluated.
objectiveThis study aimed to assess whether the addition of bone graft or dentin to the osteotomy gap during the SC procedure improves bone width, density, and implant stability compared to SC without grafting. MATERIALS AND
methodsA partially randomized prospective study was conducted on 24 implants divided into three groups: SC only, SC and bone graft, and SC and dentin graft. Clinical and radiographic evaluations, including CBCT-based bone measurements and implant stability (ISQ) values, were performed preoperatively, immediately postoperatively, and three months after surgery. All patients were followed for one year.
resultsSignificant increases in bone width were recorded in all groups, with gains exceeding 2 mm in the SC and SC and bone graft groups. The SC and dentin group showed the least bone gain and the greatest horizontal bone resorption (
conclusionsWhile bone grafting may offer modest advantages in bone preservation, the use of dentin grafting may not demonstrate significant benefits.
