Private Complete Dentures – Base plates

Base plates are the areas that is adapted over the alveolar ridges of the maxilla and mandible and allow for either wax bite rims or teeth to be placed on top of the base pllate. Similar to a foundation of building a house. Base plates tend to be made out of wax to save on costs.

Wax is material that softens and hardens in different temperatures, it distorts and adapts, you know when you get a finish denture and you say at the try-in stage it fitted, but now it’s finished it does not, that's why.

Our base plates for our private cases are made from hard light cure which allow the clinician to assess the retention, extensions and stability of their secondary impression taken.

They are done at the bite or try-in stage to allow the clinician to make the correct assessments without it dropping out of the mouth if the impression is correct.

If the base is not correct, you can simply take a light body wash inside of the base plate to rectify this, almost like a special tray.

The way we design our base plates is different, traditionally base plates are made and areas are surveyed and blocked out for insertion and removal purposes which can risk in the base plates being loose. We design ours with the base plate engaging the posterior regions of the alveolar ridges to maximise retention with minimal to none block out. This leaves the anterior section to be covered with wax to allow for better engagement of the anterior undercut due to nature of wax being soft and flexible.

Key benefits of base plates for complete dentures:

• Assess the retention, extension and stability of the base plate against the impression taken
• Allows you to take bite regs or try-in stages with minimal movement, dislodging or dropping out of the mouth to make accurate assessments.
• If the base plate is not correct simply taken a light body imp was inside the base plate to rectify this
