Original publication title: Chairside digital workflow to obtain an optimized 3D model of a partially edentulous mandible.
Plain-English summary
This article talks about a new method for creating a detailed 3D model of a dog's lower jaw when some teeth are missing. The process can be done in one visit to the vet and uses a special scanner along with a type of impression material to capture the shape of the jaw. By combining these two techniques, the vet can create a model that is accurate enough for making custom dental devices, like partial dentures. The authors suggest that this method is efficient and can help reduce the time pets need to spend at the clinic. Overall, this approach seems to work well for creating models needed for dental treatments.
Abstract
Intraoral scanners generate accurate optical impressions for dentate areas, but wide edentulous spans remain challenging due to limited stable landmarks and mobile mucosa. This article describes a single-visit, chairside workflow that combines an intraoral scan with a digitized irreversible hydrocolloid impression to obtain an optimized three-dimensional model of a partially edentulous mandible suitable for computer aided design-based removable partial denture fabrication other prosthetically driven procedures. The workflow includes intraoral scanning, conventional alginate impression taking followed by chairside digitization with the same scanner, mesh trimming and inversion to generate a positive mucosal surface, and integration of both datasets through sectioned areas and targeted best-fit alignment. The resulting composite model preserves the dentate part from the impression scan. The composite model accuracy should be validated intraorally a three-dimensional printed try-in. This fully chairside protocol provides a practical approach to producing a working mandibular model for digital prosthodontic applications for patients who require a minimal clinical appointment.
