Key Factors To Consider For Denture Relining

At dental clinic & cosmetic dentistry centre in South Perth, patients are able to opt for denture relining to make sure that the denture fit into their mouths properly, even after a time period of usage. Denture relining will also help patients to avoid irritation and speech problems that can be caused by instable dentures. Relining in dentistry simply refers to tissue resurfacing. It is done using a new material to fill the gap between the original outline and the new tissue outline of your denture. Here are some of the key factors that need to be considered for a denture relining procedure:

Border examination

For a patient who has not had a denture in the past ten years or so, the borders will need moulding. In case they look nothing like the initial denture impression, this dictates the starting point for a dental professional. What is needed is a functional vestibule. However, if the denture is unstable or tips easily, the dental professional will need to stabilise it before any moulding takes place.

This can be done by triangulating it. Your clinician will repeat this for the lower denture as well. This increases chances of accuracy in the border moulding which saves a lot of time in any adjustments. In this case, the current denture will be the custom tray.

Roughening the borders

For this to happen, the dental professional will need an acrylic bur to create a clean surface for the sake of the adhesive which will be stuck to it. In case there’s a soft tissue liner in the process of healing, make sure that the dental professional removes as much of it as possible.

Placing the adhesive


The adhesive and any other heavy body material should be segmentally placed. This should be done from right to left then finally the border that follows.

Impression material to use

You must make sure that your dental professional does not overdo with the impression material. Border moulding only requires the thickness from the tube before you can see the initial set. Once the dental professional puts the denture in your mouth, and the moulding of the muscle begins, then it will automatically better its shape. The trick is to not place it immediately after dispensing it, otherwise, it will tip off, forcing the procedure to be re-started.

Placing venting holes

For the denture base, there should be one hole on the maxillary denture and two more in the tuberosity region. This is important in case there is a flabby tissue on the inner ridge. Venting it will ensure that the tissue is not compressed so much. The holes for the lower denture should be placed on the retro molar pads. One of the holes should be on the midline that cuts across the frontal space.

Light-body material used

Be considerate of how much light-body material is used. The posterior border requires opening pressure and removal of excessive material. Not doing this means the posterior border drops down in the direction of the tongue. Moreover, the thickness of the impression material will be too much. You should be able to feel the difference from before, if your dental professional gets this right.

Completing the procedure

After levelling and seating the posterior border, the dental professional will ask you to gently bite down on the impression material. Your clinician should start by impressing and leaving the upper in place then moving onto to the impression of the lower half. At this point, make sure that you do not open your mouth even a little, and hold up your chin to achieve ideal moulding.

As you can see, the dental procedure has many pressure points that the clinician has to get right. To have denture relining done right, it’s important you opt for a reputed South Perth dental clinic to save you time and obtain the best dental results.
