3D Printed Patient-Specific Resorbable Bone Scaffolds for Alveolar Bone Regeneration.
Review in Tissue engineering and regenerative medicine, 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
backgroundAlveolar bone loss following trauma, periodontal disease, congenital anomalies, or tooth extraction poses a major challenge for oral rehabilitation, especially in implant dentistry. Traditional grafting techniques using autografts, allografts, or xenografts provide limited predictability due to issues of resorption, donor morbidity, and immune incompatibility. Advances in three-dimensional (3D) printing now enable preparation of patient-specific biodegradable scaffolds designed using 3D imaging, like cone beam computed tomography (CBCT) and computer-aided design (CAD), allowing precise replication of defect geometry and tailored biological performance.
methodsThis review article summarizes the most recent preclinical and clinical studies investigating biodegradable 3D printed scaffolds for alveolar bone regeneration. Studies were searched in the PubMed database, Scopus, and Google Scholar with the most relevant keywords related to 3D printed scaffolds focusing on alveolar bone regeneration.
resultsPolymers such as PLA, PCL, and PLGA offer mechanical stability and printability but require bioactive modification. Ceramics, including hydroxyapatite and tricalcium phosphate, provide osteoconductivity yet are brittle. Hydrogels such as gelatin and alginate support cellular viability but lack structural strength. Composite scaffolds integrating polymers with ceramics or bioactive agents demonstrated superior osteogenic potential. Clinical applications included alveolar ridge preservation, guided bone regeneration, cleft repair, and implant site reconstruction. Emerging strategies utilizing bioinks with stem cells and growth factors further enhanced the biological properties of patient-specific 3D printed scaffolds for clinical purposes.
conclusion3D printed patient-specific biodegradable scaffolds represent a promising alternative to conventional grafting, offering precise defect reconstruction, improved biological integration, and translational potential in maxillofacial surgery. Continued optimization of material printing combinations and vascularization strategies will be critical to achieving long-term clinical success.
