Occlusion is one of the most challenging topics in prosthodontics — and one of the most frequently overlooked in communication with the lab. A single note in the prescription can save 30 minutes of chairside equilibration.
An occlusal error is not just patient discomfort. It means extra chairside time, the risk of overloading implant restorations, and potential remakes. The correct occlusal scheme and precise communication with the laboratory eliminate these problems.
Two occlusal schemes, one difference—and 30 minutes of grinding if not specified in the prescription. The lab defaults to canine guidance. When is it the right choice, and when do you need group function?
An implant flexes 3–5 µm, a natural tooth 25–100 µm. This difference changes the entire occlusal strategy. How the lab designs implant-supported restorations differently and why light contact is a standard, not an option.
The patient presents with a posterior crossbite. You send the model to the lab—but fail to mention that this is the patient's normal, which you want to reproduce. The lab technician looks at the model, sees the crossbite, and thinks: 'Scanning or preparation error—I'll fix it.' The restoration arrives at your office. The patient sits, chews—and says you've changed their bite.
In eccentric movements, the mandible moves forward (protrusion) or sideways (laterotrusion). Teeth should not collide during these movements—they should either clear freely or contact in a specifically designed manner.
A new ceramic crown is seated—but with minimal occlusal interference. The natural instinct: grind the crown. This isn't always the best approach.
After delivering extensive ceramic restorations — e.max, zirconia — a patient with bruxism or parafunctions must have a protection plan. A night-time occlusal splint is part of the protocol, not an option.
For extensive changes in occlusion — increasing vertical dimension, reconstructing multiple teeth — the laboratory can prepare PMMA temporary restorations instead of immediately fabricating the final restoration. This is not just convenience for the patient, but a risk reduction strategy.
Full arch reconstruction is not 'make all my teeth at once'. It's systematic planning, a sequence of work, and testing at every stage. Errors without a diagnostic phase are costly — remaking an entire arch can cost tens of thousands of zlotys.
Bite registration is the first point of communication between you and the lab. If it's incorrect, everything beyond it is incorrect.
deltalabs. articulates models for every restoration of three units or more. Every implant case goes into an articulator. If you haven't described the occlusal scheme — we'll ask before starting work.
