Does an upper denture need a palate, and is a palateless denture possible?

What people commonly call a 'plate' is a removable upper denture. A full plate is a full denture made for an upper jaw that has lost all its teeth; a partial plate is a partial denture attached to the remaining teeth with clasps or hidden attachments. So the question 'full plate or partial plate?' is not a matter of preference; it is decided by whether there are sound teeth left in the mouth to hold on to. As Cleveland Clinic describes it, a full denture sits on top of the gums and, in the upper jaw, takes support from the palate, while a partial denture gains extra stability from clasps that hold on to the remaining teeth.

In an upper jaw with no teeth, there is no screw or clasp holding the denture in place. In the words of the Oral Health Foundation, a full denture stays in place by suction. According to the literature summarised in a 2016 study by Kaur and colleagues, adhesion, the cohesion within the saliva itself, surface tension, atmospheric pressure, a close fit of the denture to the tissues, a sealed edge and muscle control all contribute to retention together; of these, the single most important factor is the border seal. A study cited by the same source concluded that a seal at the back of the palate is needed for the best retention of a full upper denture.

The same study's own measurement shows how important the edge is: the force needed to dislodge denture bases made from impressions in which the edges had been shaped to the movement of the tissues in the mouth was on average 59.4% higher than for bases made without this shaping. The palate provides the back boundary of this seal and the broad surface the denture sits on. When the middle of the palate is opened up, the denture becomes horseshoe-shaped and sits on a narrower area, and the sealed edge has to be re-established along the palatal ridge.

On how much reducing the palate of a conventional full denture actually affects retention, the comparative evidence is limited and mixed. A 2025 review (Jandaghian and Zeighami) states that removing the palatal coverage has little effect on retention even in conventional dentures, provided the bony bulges at the back of the jaw are well covered; however, the source it cites for this statement is a laboratory study carried out on implant dentures, and the other studies on the subject that it mentions also concern implant-supported dentures. El-Amier and colleagues, on the other hand, write that removing the palate has a negative effect on the retention of an upper denture, and that this is why implants are added. Meanwhile, a 2021 systematic review published in BMC Oral Health points out that as the bone in the upper jaw shrinks, people who wear conventional dentures experience a loss of retention and stability. A design change that would reduce the hold even further in a jaw that has already shrunk is therefore weighed carefully.

It is also clear that covering the palate comes at a price. The Jandaghian review states that palatal coverage in conventional dentures has been associated with negative effects such as a reduced sense of taste and disrupted saliva flow. According to the BMC review, patients prefer a palateless denture for comfort, taste, speech, control of the gag reflex, saliva flow and ease of cleaning. We cover gagging separately on our page about gagging with a denture.

The most studied way to uncover the palate is an implant-retained denture. In 11 of the 15 studies examined in the BMC review, the denture was designed in a horseshoe shape, that is, without a palate; a denture on a bar connected to four implants did no worse than one on six implants in terms of patient satisfaction, implant and denture survival, and denture problems. It should also be noted that the randomised studies had a high risk of bias. The Jandaghian review states that the number and position of implants are debated, but that most studies converge on at least four implants in the upper jaw.

The position of the implants matters too. A 2016 systematic review published in an international implant journal (Sadowsky and Zitzmann) reports that palateless designs resting on four to six implants, with a wide spread between the front and back implants, have been used successfully in some studies; the authors also write that larger and longer randomised studies are needed. In a 2018 laboratory study, too, the retention of a palateless denture increased as the distance between the front and back implants grew. The option that leaves the palate completely uncovered is fixed teeth on implants; this is the area our clinic works in.

The distinction below is based on what the denture will hold on to. Seeing yourself in the second list does not mean a palateless solution is impossible; it means that uncovering the palate with the support you have today is risky.

The sequence below aims first to pin down the problem with your current denture, and then to see whether the support needed to leave the palate uncovered can really be put in place.

1. 1

   Mapping the situation in your mouth

   Your remaining teeth, the height of the bony ridge, the amount of saliva and the edges of your current denture are assessed. The answer to the question 'full or partial?' comes out of this step.

2. 2

   Pinning down the problem with your current denture

   Gagging or looseness sometimes comes not from the palate but from a back edge that is too long or a base that does not fit. In that case, an adjustment or relining may be enough.

3. 3

   CBCT scan

   If implants are being considered, the volume of bone, the position of the sinuses and the areas where implants can go are determined with a three-dimensional image. The distance between the front and back implants affects the retention of a palateless design.

4. 4

   Choosing the design

   The choice between a partial denture, an implant-retained denture and fixed teeth on implants is made according to your bone, the number of implants, your cleaning habits and your expectations.

5. 5

   Choosing the attachment system for a removable denture

   The denture can clip onto a bar or onto separate attachments on each implant. According to the Sadowsky and Zitzmann review, separate attachments need maintenance more often, while gum inflammation is seen more often under a bar.

6. 6

   Three days, if fixed teeth are chosen

   In our protocol, on day 1 a CBCT scan is taken and the plan is reassessed, the implants are placed, a digital impression is taken and the first try-in teeth are made within a few hours; on day 2, the try-ins settle your bite, appearance, speech and final shade; on day 3, the final teeth are fixed in place. You can go home at the end of day 3; further check-ups follow the clinic's follow-up plan.

The options below are listed according to how much of the palate they cover. Asking your dentist the following makes the comparison easier: Will the denture stay in if the palate is uncovered in my jaw? For a palateless removable denture, how many implants are planned, and in which areas? A bar or separate attachments, and why? Am I suitable for fixed teeth?

A palateless solution brings comfort, but every route has its own price. Discuss these points with your dentist before you decide.

How you adapt depends on the solution chosen. The sequence below gives a general outline for the implant-supported options that leave the palate uncovered.

1. The first few days

   Your tongue finds new room on the palate, and for most people speech adapts within a short time. Because the palate is uncovered, you feel the heat of hot drinks on your palate again; bear this in mind in the first few days.

2. With fixed teeth, after day 3

   You go home with your final teeth in place. The clinic's follow-up plan sets out when you can move on to which foods and when your check-ups are.

3. With a removable denture, the first few weeks

   You learn to put the denture in and take it out, and to clean around the attachments. The denture is taken out and cleaned at night.

4. In the long term

   The areas around the implants and the attachments are checked regularly. With a removable denture, it is normal for the attachments to be replaced at intervals.

We do not give figures on this page; the scope of a denture that covers the palate and that of an implant solution that leaves it uncovered are very different. The main items that determine the scope are these:

The support chosen

A partial denture that holds on to teeth, an implant-retained denture and fixed teeth on implants are separate procedures with separate timescales.

The number and position of implants

For a palateless removable denture, at least four implants are usually planned; for fixed teeth, the number is set according to the condition of the bone.

The attachment system

A bar and separate attachments require different laboratory work and different maintenance schedules.

Preparing the mouth

Teeth that need extracting, gum treatment or the use of your current denture during the transition are added to the plan.

Imaging and check-ups

A CBCT scan is needed for an implant plan; with a removable denture, maintaining the attachments is part of the long-term picture.
