Diagnosis and Treatment Plan
The patient presented with generalised tooth loss and structurally compromised dentition, warranting full-arch prosthetic rehabilitation. A comprehensive clinical and radiographic assessment informed a dual-arch restorative approach, optimising both functional and aesthetic outcomes based on residual hard and soft tissue anatomy.
Maxillary Arch
The upper arch demonstrated sufficient bone volume and favourable soft tissue contours, particularly in the aesthetic zone. This made it an ideal candidate for an FP1-type fixed prosthesis supported by five dental implants.
An FP1 prosthesis replaces only the clinical crowns and is retained by implants placed in a ridge with minimal vertical bone loss. This type of restoration allows for excellent emergence profile design and soft tissue integration, provided there is adequate tissue volume for contour development.
Mandibular Arch
In contrast, the lower arch exhibited greater ridge resorption, particularly posteriorly, with compromised vertical and horizontal tissue dimensions. To address this, a combination approach was implemented:
- Posterior FP3 prostheses, which replace both crowns and a portion of the missing soft tissue, We selected this kind of prosthesis to manage aesthetic and functional limitations due to volume loss.
- Adhesive onlays were placed in sites where native tooth structure and occlusal stability could be predictably preserved.
This differential approach allowed for the most appropriate treatment designed based on site-specific anatomy, preserving existing structure while optimising prosthetic contour and hygiene access.
