A telescopic crown is an artificial crown meticulously designed and fabricated to fit precisely over an existing coping.
Understanding the Telescopic Crown
Definition
Based on its dental definition, a telescopic crown is an artificial crown fabricated to fit over a coping (1). This distinctive design implies a two-part system where the telescopic crown acts as the outer, secondary crown. It is engineered to slide smoothly and securely over an inner primary crown, known as a coping, which is typically cemented onto a natural tooth or a dental implant.
Primary Application in Dentistry
Telescopic crowns are primarily utilized within the field of removable dental prostheses (RDP). Their core function in this application is to connect the dentures to the remaining dentition (2, 3). This connection is crucial for enhancing the stability and retention of the prosthetic appliance, providing a secure fit that supports chewing and speaking functions.
Key Features and Functional Role
Telescopic crowns play a vital role in providing a stable foundation for removable dentures. Their design facilitates a secure and precise fit that improves the overall performance of dental prostheses.
| Feature | Description | Reference |
|---|---|---|
| Type | An artificial crown | (1) |
| Fit Mechanism | Fabricated to precisely fit over a coping (an inner crown) | (1) |
| Main Use | Primarily used in removable dental prostheses (RDP) | (2, 3) |
| Core Function | To connect the dentures securely to the patient's remaining natural teeth or dental implants | (2, 3) |
Benefits for Removable Dental Prostheses
The use of telescopic crowns offers several practical advantages, especially in the context of removable dental prostheses:
- Enhanced Stability: By providing a precise, friction-fit connection, telescopic crowns significantly improve the stability of removable dentures, reducing unwanted movement during daily activities.
- Improved Retention: They offer a robust retentive mechanism, ensuring the denture stays firmly in place, which is crucial for patient comfort and confidence.
- Secure Connection: They serve as an effective link between the artificial denture and the patient's natural supporting structures (teeth or implants), contributing to a more natural feel and function of the prosthesis.
