AI in Prosthodontics — Where it Really Helps, and Where it Doesn't

AI in prosthodontics isn't about robots designing bridges or algorithms replacing experienced technicians. It's about specific tools supporting specific stages — and when used wisely, they genuinely accelerate work and reduce errors. Below is a practical overview: what works, what doesn't, and where it's hardest to separate marketing from reality.

Where AI Has Real Application

Preparation Detection. The algorithm identifies irregularities from the scan before the technician starts designing — too thin a wall, incompletely exposed margin, insufficient convergence. The technician receives a flag and can either request a correction or adjust the design. At deltalabs., this is a standard step — the scan arrives, the algorithm flags problems, and the technician's judgment dictates the next move. Automated Design. Software like exocad DentalCAD or 3Shape Design Studio offers an auto-design mode: the system generates a proposed crown or bridge design based on scanner data and an anatomical shape database. The technician corrects, not designs from scratch. The real saving is 20–30% of time for simple jobs — smaller crowns and bridges up to three units. Color Matching. Applications like Vita Easyshade 5 with an AI module analyze the patient's photo and indicate the VITA shade key. It doesn't replace the technician's assessment but provides a starting point instead of lengthy manual trial-and-error.

Where AI Cannot Replace the Technician

Designing Complex Restorations. AI lacks the ability to think strategically about the entire case — how to coordinate eight teeth, where the compromise between aesthetics and function lies, what to prioritize with limited space. This is always the decision of an experienced technician. Biological Decisions. Cement selection, material choice for a specific patient (age, parafunction, periodontal status, bone preservation), implant tolerance — these decisions require clinical experience and knowledge of biomechanics. AI can suggest, but should never decide. Communication with the Dentist. Interpreting the dentist's intentions — "I want something natural, but not too soft" or "the patient has bruxism, so I'd like a stronger occlusion" — still requires a human on the other end of the conversation. Color Assessment in Difficult Cases. Dentin discoloration, metal show-through, transparent ceramics against dark dentin, changes in optical state under spotlight — these cases go beyond the capabilities of algorithms.

Typical Exaggerations in AI Marketing

The most common pitfall: a laboratory buys software advertised as "AI design" because it sounds modern at a conference. The software is good, but expectations are inflated. Reality: AI speeds up work by 20–30% for simple, standard tasks. The technician still has to check and correct everything. It's an aid, not a replacement — and anyone who claims otherwise either doesn't understand the technology or is trying to sell it. At deltalabs., auto-design and preparation analysis are standard — however, the CAD technician always has the final say.
