Common Denture Design Considerations
We need to plan ahead
With partial dentures, depending on how many, and which arrangement of teeth you have missing, the choice combinations get quite complicated with lots of options in denture base choice, design and different kinds of clasps. For all partial dentures, we need a prescription from a dentist prior to making them, to ensure we know all about the health of your remaining teeth.
- Do any real teeth need treatment first? (flattening spiky roots/smoothing off sharp edges/tooth extractions).
- Do we plan what’s called an “immediate denture” which is when the denture is made ready before your loose teeth are extracted and fitted in your mouth filling the gaps straight away?
- Do you need to see the hygienist, to remove scale build up first?
- Do you want to get your remaining teeth bleached first so the denture teeth can be shade matched afterwards for a whiter smile?
- Will an acrylic base make you lisp or have a gag reflex or is a thin chrome alloy denture more suitable?
- How far should the denture cover your palate? What can you tolerate? I use a system I call palate mapping to assess it before your denture is made.
- Is hard acrylic strong enough or do you need a stronger thin alloy base because of your jaw relationship and bite?
- Will it stay in or do you need clasps?
- Which kind of clasps – wire or tooth coloured/clear flexi clasps?
- Which real remaining teeth are healthy enough or have adequate curves and angles to take clasps?
- Can we make your partial without clasps to lock in place using the natural angles of your real teeth?
Future Proofing your Partial Denture
There is a huge amount of thought that has to go into the design of a partial denture to accommodate making them as future proof as possible as well as maintaining the health of your remaing teeth. The other design consideration is to accommodate predictable future tooth loss in the design allowing for the successfull addition of new denture teeth resulting in an adapted but still fully functional denture.
Clasps or No Clasps
We try not to make acrylic partial dentures with wire clasps which can wear into real teeth and are visible. In some cases we can get partial acrylic dentures to “click in “ using the natural angles and flexibility of the acrylic around the curvature of your remaining real teeth to hold and lock them in place which I call “flex lock”. “Cam lock” is another option using a carved rotational path of insertion for a partial denture to lock into place.
Chrome alloy dentures have the option of flexible clear or tooth shade matched clasps often offering a far better solution.
