How does a telescopic denture stay in place?
A telescopic denture is a removable restoration retained by interlocking double crowns. Inner crowns remain on the prepared abutment teeth. Matching outer crowns form part of the denture. The two parts slide over one another when it is inserted.

Two crowns fit together
The inner crown stays fixed to the prepared tooth. The matching outer crown sits within the denture. Together, they form its retaining element.
The supporting teeth must be suitable
The remaining teeth, gums and ability to withstand forces are assessed first. Tooth structure must be removed to make room for the crowns. The design depends on the findings.
Remove, clean and check
The denture is taken out for cleaning. Inner crowns and denture are cared for separately. A change in retention or sore spots should be checked at the practice.
At a glance
Who might it suit?
People with suitable abutments and overall oral conditions. Remaining teeth, gums, space requirements and handling need assessment.
What does treatment involve?
The abutments are prepared, and the double crowns and denture are made and fitted. Cleaning and checks of both parts remain important afterwards.

Often confused
Telescopic crown or single dental crown?
A telescopic crown is part of a matching double-crown system that retains a denture. A conventional single crown replaces the external shape of a tooth.
Quick answers
Is a telescopic denture permanently fixed?
Only the inner crowns are fixed to the abutment teeth. The denture containing the outer crowns is removable and is taken out for cleaning.
Can it always be made without covering the palate?
No. The coverage required depends, among other things, on the number, position and load-bearing capacity of the abutments. A design that leaves the palate uncovered cannot be promised in every case.
Why do the abutment teeth need reshaping?
The inner and outer crowns need space. Planning must establish how much tooth structure would need removal and whether the teeth are suitable abutments.

For your consultation
A question to discuss with Dr. med. dent. Niusha Barahmand Pour:
Which of my teeth would be suitable abutments, and what would preparing those teeth involve?
Before a restoration is selected, her practice assesses the dental starting situation and the requirements.
The suitability of the abutment teeth and the denture design can be assessed from the findings.

- Primary crown
- The inner crown of the double-crown system, fixed to a prepared abutment.
- Secondary crown
- The matching outer crown incorporated into the removable denture.
- Abutment tooth
- A tooth used to support or retain a dental restoration; its suitability must be assessed.
Know the difference
Primary and secondary crowns are the two matching parts, not two replacement crowns fitted one after another.
