Wrong occlusal scheme in full-mouth / multi-unit cases
What it is
Planning or delivering a full-mouth rehabilitation (or multi-unit fixed prostheses) with an occlusal scheme that does not match the patient's biology and case requirements — for example: • choosing balanced articulation concepts meant for complete dentures in a dentate fixed case • creating non-working side interferences, unstable centric contacts, or an anterior guidance/posterior guidance relationship that overloads teeth/restorations Occlusal schemes are classically discussed as mutually protected articulation, group function, and balanced articulation, and the "right" choice depends on the clinical situation (natural dentition vs complete dentures, etc.).
Why it happens
• No structured occlusal diagnosis (skipping a full exam + articulated casts / jaw relation analysis), then "copying" the existing compromised occlusion • Mixing philosophies (e.g., trying to build a denture-style balanced scheme into a fixed dentate case, or creating guidance without controlling interferences) • Not classifying occlusal risk/complexity: comprehensive prosthodontic diagnosis systems explicitly include occlusal scheme as a key diagnostic criterion for complexity/compromise • No "wax-up → provisional → refine → finalize" pathway: skipping a provisional phase removes your chance to test guidance, comfort, muscle/joint response, and function before final ceramics
