Implant Placement and Immediate Provisionalization After Alveolar Ridge Reconstruction in the Aesthetic Zone Using a Digital Workflow: A 1-Year Prospective Case Series Study.
Article in Clinical oral implants research, 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
introductionIn single-tooth replacement in the aesthetic zone, extensive bone defects require alveolar ridge reconstruction. A digital workflow involving CBCT and intraoral optical scanning enables a three-dimensional assessment, prosthetically driven implant positioning, computer-assisted implant surgery, and prefabrication of a temporary restoration for immediate provisionalization. The aim of this study was to assess the clinical, aesthetic, radiographic, and patient-reported outcomes of delayed implant placement and immediate provisionalization in reconstructed alveolar ridges using a digital workflow. MATERIALS AND
methodsIn a prospective case series, 30 patients with a > 5 mm buccal bone defect underwent alveolar ridge reconstruction. After 4 months, implant placement was performed using a digital workflow, followed by immediate provisionalization with a prefabricated temporary restoration, and definitive restoration 3 months later. The clinical, aesthetic, radiographic, and patient-reported outcomes were assessed pre-treatment, 6 weeks after provisionalization, and 1 month and 1 year following definitive restoration.
resultsWound healing was uneventful in 90% of cases (10% showed mild oedema). One early implant failure occurred (implant survival rate 97%). After 1 year, restoration survival and success rates were 100% and 97%. Peri-implant tissues were mainly healthy. The mean (SD) Pink and White Esthetic Score (scale 0-20) was 14.0 (2.9). The mean (SD) marginal bone level change was -0.25 mm (0.38) mesially and -0.21 mm (0.45) distally. The median buccal bone thickness was > 1.5 mm. Patient satisfaction (scale 0-10) was 9.3 (0.9).
conclusionA digital workflow offers favorable short-term clinical, aesthetic, radiographic, and patient-reported outcomes for single-tooth implants after alveolar ridge reconstruction.
