L- shape symphyseal autogenous bone block for alveolar ridge augmentation in anterior maxilla and mandible, a prospective single arm clinical study.
Article in BMC oral health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundAlveolar ridge augmentations are challenging procedures in dental implantology, especially in esthetic zone. 3D alveolar defects can be treated by guided bone regeneration (GBR), distraction osteogenesis, or bone blocks. This study introduces a new technique for 3D-alveolar ridge augmentation by using L-shape autogenous symphyseal bone block. PURPOSE: This study aimed to assess both horizontal and vertical alveolar bone augmentation for severe atrophied anterior maxilla and mandible, using an L- shape autogenous bone block harvested from the symphysis. PATIENTS AND
methodelven partially edentulous patients who needed horizontal and vertical bone augmentation in the anterior maxilla or mandible before implant placement were selected for this study. For each patient, an autogenous bone block was harvested from the symphysis, trimmed to L-shape, and used to augment the anterior maxilla or mandible horizontally and vertically. Horizontal and vertical bone gain was measured by CBCT immediate postoperative and at 6months postoperatively.
resultsIn this study, 14 L-shape bone blocks were grafted in 11 patients. The patients were 4males and 7females, with a mean age of 24.63years. Healing was uneventful for all patients with no sensory disturbance. The Mean of horizontal bone gain was 4.17 ± 0.77 mm immediate postoperative, and was 3.52 ± 0.75 after 6months. While, the mean of vertical bone gain was 6.51 ± 1.01 mm immediate postoperative, and was 4.74 ± 1.03after 6months. The mean of horizontal and vertical bone loss was 0.74 ± 0.24 mm and 1.62 ± 0.19 mm after 6 months, respectively.
conclusionUsing L- shape autogenous bone block harvested from the symphysis for alveolar ridge augmentation is a safe, predictable and effective method for 3D ridge augmentation.
