How Are Dentures Fitted? A Step-by-Step Overview from a Dental Lab in NZ

If you're considering dentures for the first time, or helping a family member explore their options, it's natural to wonder what the process involves. Getting dentures fitted is not a single appointment - it's a staged process that takes place over several visits.

Understanding each step can help you feel more prepared and know what to expect along the way. The process involves both your dental team and a dental lab, working together to create a restoration that fits comfortably and functions well.

At IDD Dental Lab, a dental lab in NZ, we work with dental clinics to fabricate custom dentures for patients across the country. Here is a straightforward overview of how dentures are typically fitted, from the first consultation through to final placement.

What Are Dentures?

Dentures are removable prosthetic devices designed to replace missing teeth and surrounding gum tissue. They can replace all of the teeth in an arch (complete dentures) or just some of the missing teeth (partial dentures).

Modern dentures are custom-made to suit each patient's mouth. They are designed to restore function - such as chewing and speaking - and to support the appearance of the face and smile.

Dentures in NZ are made from materials such as acrylic resin, nylon, or a combination of acrylic and metal. The specific material and design depend on the type of denture and the patient's clinical needs.

Step 1: Initial Consultation and Assessment

The process begins with a consultation with your dentist or dental prosthetist. During this appointment, your oral health is assessed to determine whether dentures are a suitable option and which type may be most appropriate.

Your dentist will examine your remaining teeth, gums, and jaw structure. X-rays may be taken to get a clearer picture of the underlying bone and tissue.

If any teeth need to be extracted before dentures can be fitted, this will be discussed and planned at this stage. Your treatment plan will be outlined, including an estimated timeline and costs.

Step 2: Taking Impressions of Your Mouth

Once a treatment plan is in place, your dentist will take impressions of your upper and lower arches. These impressions capture the precise shape of your mouth and form the foundation for your custom dentures.

Initial impressions are usually taken using a putty-like material pressed into trays that fit over your gums. These produce a detailed mould of your mouth's shape and contours.

The impressions are sent to a dental lab in NZ, where they are used to create study models - plaster casts of your mouth. These models guide the entire fabrication process.

Step 3: Recording Your Bite and Jaw Relationship

Getting the bite right is one of the most important parts of the denture fitting process. Your dentist will take measurements to record how your upper and lower jaws relate to each other when your mouth is closed.

This is done using wax bite rims - horseshoe-shaped wax blocks that help establish the correct vertical height and bite position. Your dentist will make careful adjustments until the alignment feels right.

These measurements are sent to the dental lab along with your impressions. The lab uses this information to mount the study models on an articulator - a device that simulates jaw movement - to ensure the denture teeth are positioned correctly.

Step 4: Shade and Tooth Selection

At this stage, you and your dentist will choose the shade, shape, and size of the denture teeth. The goal is to select teeth that look natural and suit your facial features.

Factors considered include your skin tone, the shape of your face, your age, and - where relevant - the appearance of any remaining natural teeth. Photographs may be used as a reference point.

A dental  will source denture teeth from a range of options and set them according to the specifications provided by your dentist. The aim is a result that looks natural and feels appropriate for your individual circumstances.

Step 5: Try-In Appointment

Before the final denture is processed, a wax try-in is completed. At this appointment, you'll be given a trial version of the denture - with the teeth set in wax - so that both you and your dentist can assess the fit, appearance, and bite before anything is finalised.

This is an important opportunity to make adjustments. The position of the teeth, the shape of the gum-coloured base, and the overall appearance can all be modified at this stage without significant rework.

Feedback you give at the try-in is communicated back to the dental lab, where any changes are made before the denture goes through final processing.

Step 6: Denture Processing and Fabrication

Once the try-in is approved, the denture is sent back to the dental lab to be processed into its final form. The wax is replaced with a durable acrylic base, and the teeth are permanently set in place.

The lab carefully finishes and polishes the denture to ensure smooth surfaces that are comfortable against the gum tissue. Precision at this stage affects both the comfort and longevity of the final restoration.

The quality of the fabrication work plays an important role in how well the denture fits and functions. A skilled dental lab will take care at every step to produce a well-finished, accurate restoration.

Step 7: Fitting and Adjustment

When the finished denture is returned to the dental clinic, your dentist will fit it in your mouth and check for any pressure points, areas of discomfort, or bite issues.

It is common to need minor adjustments after the initial fitting. Small areas of the denture base may be relieved to reduce irritation, and the bite may be fine-tuned to ensure even contact between the upper and lower teeth.

You may be asked to return for one or more follow-up appointments in the weeks after fitting. This is a normal part of the process - minor adjustments help ensure the denture settles comfortably as you get used to wearing it.

Step 8: Review and Ongoing Care

After the denture has been fitted, your dentist will schedule a review appointment to check how it is settling. At this point, any further refinements can be made if needed.

Regular dental check-ups remain important even for patients with full dentures, as your dentist will monitor the health of your gums and underlying bone over time.

Dentures may need to be relined or replaced as the shape of the mouth changes with age. Keeping up with routine reviews helps ensure your denture continues to fit well and function as intended.

FAQ

How long does it take to get dentures fitted?

The full denture fitting process typically takes several weeks from the first impression to the final fitting. The exact timeline depends on the complexity of the case, whether extractions are needed, and the turnaround time at the dental lab.

Your dentist will give you a realistic estimate at your initial consultation. In some cases, immediate dentures can be placed on the same day as extractions, though these often require relining or replacement once the gums have healed.

Will dentures feel uncomfortable at first?

It is normal to experience some initial discomfort, increased saliva flow, and difficulty speaking or eating when you first start wearing dentures. These sensations usually ease as you adjust to the new appliance.

If you experience persistent sore spots or significant discomfort, contact your dental team. Minor adjustments can often resolve these issues quickly. Adjustment appointments are a routine part of the process.

Can dentures be made to look natural?

Yes. Modern dentures are designed to look natural, with tooth shade, size, and shape selected to suit each patient's individual appearance. A dental lab will craft the gum-coloured base to closely resemble natural gum tissue.

Results vary depending on the complexity of the case and the materials used. The try-in appointment gives you and your dentist an opportunity to review the appearance before the denture is finalised.

How do I look after my dentures?

Dentures should be cleaned daily using a soft brush and a non-abrasive denture cleaner. Avoid using regular toothpaste, which can scratch the surface of the acrylic.

Remove your dentures at night to allow your gum tissue to rest. Store them in water or a denture-soaking solution to prevent them from drying out. Handle dentures carefully over a soft surface or basin of water, as they can break if dropped.

Conclusion

Getting dentures fitted involves a careful, multi-step process designed to achieve a comfortable fit and a natural result. From the initial impressions through to the final fitting and follow-up adjustments, each stage plays an important role in the outcome.

The collaboration between your dental team and a dental lab ensures the restoration is fabricated to precise specifications. If you are considering dentures, speaking with a registered dental professional is the best first step. A personalised treatment plan can be discussed during a consultation based on your individual needs.
