What are screw-on implant crowns?
With the development of technology in dentistry, implant crowns can be made in a variety of ways, depending on the construction technique, materials used, type of application, and implant-crown connection.
Screw-on implant crowns are crowns that are connected to the implants by screws. Screw-on crowns are preferred in cases where the implant is placed deep in the bone due to the fact that there is a lot of bone loss. Screw-on crowns are easier to clean and less risky than crowns that are glued to the implant using a bonding agent called cement. Screw-on crowns also make it easier to access the crowns or tissues around the implants. In the case of any problem with the crown (such as porcelain chipping or fracture), the crown can be easily removed and repaired by unscrewing it. If the crown cannot be repaired, it can be easily replaced. Screw-on crowns can be removed from the mouth for cleaning, which allows for better cleaning of the crowns and the areas below.
The cost of screw-on crowns varies depending on the system used. Generally, screw-on crowns do not add any additional cost. However, in some cases, your dentist may need to use intermediate components, which will increase the cost of the treatment.
Screw-on crowns are not always applicable. The best answer to this question will be determined by your dentist after evaluating your mouth structure and the treatment option that is best for you.
Why do we prefer screw-on crowns for implant-supported prostheses?
Cements are the bonding agents that are used to glue crowns to implants. However, cements can be difficult to clean completely, especially in cases where the implant is placed deep in the bone due to the fact that there is a lot of bone loss. This can lead to the accumulation of bacteria and plaque around the implant, which can increase the risk of infection.
Screw-on crowns do not require cements, which makes them easier to clean and less risky. In addition, screw-on crowns can be easily removed and replaced if necessary, which can be beneficial if the crown is damaged or if the patient needs to change the shape or size of the crown.
Are screw-on crowns always applicable?
No, screw-on crowns are not always applicable. In some cases, the patient’s mouth structure may not be suitable for screw-on crowns. For example, if the patient has a very thin layer of bone, the implant may not be able to support the weight of a screw-on crown. In these cases, other types of crowns, such as cemented crowns or adhesive crowns, may be more appropriate.
The best way to determine whether screw-on crowns are right for you is to talk to your dentist. Your dentist will be able to evaluate your individual needs and make a recommendation about the best type of crown for you.
