We replace the traditional putty impression with an intraoral scan that creates a precise digital model of the mouth. The lab designs the prosthesis with CAD software and manufactures it with a milling machine or 3D printing.
The result is a more precise, more comfortable prosthesis with a better aesthetic fit, and fewer try-in and adjustment visits than with the traditional workflow.
Types of prosthesis
Prostheses are classified by what supports them, on natural teeth or on implants, and by material, porcelain or resin. They can also be:
- Fixed: cemented or screwed in, and not removed by the patient. These include crowns, bridges and full prostheses on implants.
- Removable: the patient can put them in and take them out for cleaning. Usually indicated when several teeth are missing and a more affordable solution is wanted, or when the condition of the bone doesn’t yet allow other options.
The choice depends on the specific needs of each case, which we assess at the first visit. When the main goal is improving the look of teeth that are still present, without replacing missing ones, the alternative is usually a dental veneer rather than a prosthesis.
Caring for your prosthesis
- Fixed: cared for like natural teeth, with brushing and floss or interdental brushes, paying special attention to where the prosthesis meets the gum.
- Removable: removed for daily cleaning with a specific brush, and stored in water or a cleaning solution when not being worn.
In both cases, regular check-ups allow any misfit to be caught early, before it affects the teeth or implants providing support.
Related treatments
- Prosthesis on Natural Teeth Fixed or removable prostheses supported by your own natural teeth, indicated when the neighbouring teeth are healthy and can act as support.
- Prosthesis on Implants Fixed or removable prostheses anchored onto dental implants, with no need to wear down natural teeth, offering superior fit and stability.
Frequently asked questions
What's the difference between a fixed and a removable prosthesis?
A fixed one is cemented or screwed in and the patient doesn't remove it; it feels and works like your own tooth. A removable one can be put in and taken out by the patient for daily cleaning. The choice depends on how many teeth need replacing, the condition of the bone and each patient's preferences.
Is a prosthesis on implants better than one on natural teeth?
It depends on how many teeth have been lost and the condition of the neighbouring teeth. On implants, it avoids wearing down healthy teeth to act as support, while on natural teeth it can be a faster, more affordable solution when those teeth are in good condition.
How long does a dental prosthesis last?
A well cared-for fixed porcelain prosthesis can last more than 10-15 years. Removable ones usually need adjusting or renewing every 5-7 years, depending on wear and changes in the gum and bone.
Does intraoral scanning fully replace putty impressions?
In the vast majority of cases, yes. It's more comfortable, doesn't cause gagging and the digital model is more precise, which results in a better-fitting prosthesis from the first try-in.
