Prosthetic Index
A pre-surgical diagnostic template or digital plan that communicates the intended prosthetic outcome to guide implant positioning.
Full Definition
A prosthetic index (also called a radiographic stent or surgical template in related contexts) is a planning instrument used to align implant placement with the requirements of the final restoration, embodying the principle of 'restoratively driven implant placement'. It may be a physical acrylic stent or a digitally designed guide derived from prosthodontic wax-up or digital smile design data. Editors should be aware that 'prosthetic index', 'surgical stent', 'radiographic guide', and 'surgical guide' are related but not always synonymous terms; authors must define their specific use. This concept underpins treatment planning discussions in pre-surgical workup reports and multidisciplinary case articles.
Usage
Usage note: Not interchangeable with 'surgical guide' in peer-reviewed articles; confirm the author's specific meaning and ensure consistent use throughout the document.
