What is screw retained crowns / prosthesis

In conventional dentures that are cemented and directly adhered to the mouth, cement (adhesive) residues may escape into the gingiva and go towards the implant surface, even with careful gluing. Since the prosthesis cannot be removed, these cement residues can damage the gingiva, bone, and implant, and are the most important cause of long-term failure in implant treatments.

In screwed prostheses, there is no bonding process necessary, or it is done outside the patient's mouth. The biggest advantage of this approach is that it can be easily removed by accessing the screws from the screw holes on the crowns. In contrast, with the cemented approach, the cement has to be tried to be cracked and removed with impacts that may disturb the patient. Sometimes, it may not even be possible to remove the cement, and the prosthesis may need to be cut out and made again from scratch. Impacts to displace cemented prostheses can cause screw and neck fractures in implants or extra breaks in the prosthesis.


Screw-retained crowns or prostheses offer several advantages in dental restorations. One significant advantage is the ease of repair if any porcelain flakes or fractures occur. The prosthesis can be easily removed, allowing for straightforward repairs or small additions to be made, such as addressing gingival recessions over time. Similarly, if there is excessive pressure on the gingiva, tiny adjustments can be made by removing small pieces from the prosthesis.


In cases where implants are placed adjacent to natural teeth, contact problems between the natural tooth and the implant crown can arise over time, leading to food entrapment. Screwed prostheses allow for easy resolution of these contact problems by removing the prosthesis.


Loosenings of abutment screws connecting with the implant can sometimes occur. Unlike cemented prostheses, where tightening the screw necessitates prosthesis removal, screw-retained prostheses offer easy solutions to address screw-related issues. Additionally, removing the prosthesis at regular intervals allows for cleaning both the prosthesis and the mouth.


Screw systems provide patient comfort by requiring fewer implants, especially in the All-on-four approach. By placing only four implants in areas of healthy bone and utilizing crown extensions called "wings," the need for advanced surgeries like sinus lifting or bone grafting can be avoided. This shortens the treatment process, as immediate implant placement becomes possible, eliminating the need for additional months of healing time. The reduction in advanced surgical procedures and the number of implants also contributes to cost savings for the overall treatment.


Advantages of Screw-Retained Crown Solutions

Screw-retained crowns offer numerous benefits compared to other dental restorations. These advantages include:

Enhanced stability: The use of a screw provides increased stability, reducing the risk of the crown becoming loose or dislodged over time.


Easy removal and replacement: The screw-retained design allows for easy removal and replacement of the crown if needed, without requiring the entire restoration to be replaced.


Reduced risk of chipping or breaking: Screw-retained crowns are typically made from strong and durable materials like zirconia or ceramic, minimizing the risk of chipping or breaking that can occur with other restoration types.


Aesthetically pleasing appearance: Screw-retained crowns can be fabricated using materials that closely resemble the natural color and translucency of teeth, resulting in a more aesthetically pleasing outcome.


Reduced risk of bacterial growth: Unlike cemented restorations, screw-retained crowns do not require adhesive materials or cement, which can create spaces for bacterial growth. This design helps minimize the risk of bacterial accumulation and related oral health issues.


Overall, screw-retained crowns offer a durable and reliable solution for individuals with missing teeth or in need of dental restoration. Consulting with a dental professional will help determine if a screw-retained crown is the most suitable option for your specific dental needs.


Frequently Asked Questions

Screw-retained crowns and cemented crowns are two common methods of attaching dental crowns to implants or abutments. Here are some key differences between the two:

  1. Attachment Method: Screw-retained crowns are secured to the implant or abutment with a small screw, whereas cemented crowns are bonded in place using dental cement.

  2. Accessibility for Maintenance: Screw-retained crowns can be easily removed and replaced if needed, which allows for easier maintenance, repair, or adjustments. In contrast, cemented crowns require the removal of the entire restoration to make any changes.

  3. Retrievability: Screw-retained crowns can be easily retrieved and accessed for further treatment or adjustments. Cemented crowns, on the other hand, can be more challenging to retrieve, as they are firmly bonded to the abutment or implant.

  4. Aesthetics: Cemented crowns may offer better aesthetic results, as there are no visible screws or access holes on the outer surface of the crown. Screw-retained crowns, however, may have small access holes that can affect the overall aesthetics, particularly for front teeth restorations.

  5. Long-Term Stability: Screw-retained crowns generally provide better stability due to the mechanical retention provided by the screw. Cemented crowns rely on the bonding strength of the dental cement, which may be prone to degradation over time.

  6. Maintenance and Repair: Screw-retained crowns allow for easier access and repair if any issues arise, while cemented crowns may require the complete removal of the restoration for repairs or adjustments.

The choice between screw-retained crowns and cemented crowns depends on various factors, such as the implant location, aesthetics, accessibility for maintenance, and the patient's individual needs. It is important to consult with a dental professional to determine which option is most suitable for your specific case.

Screw-retained ceramic crowns are a type of dental restoration that is used to replace a missing or damaged tooth. This type of crown is made of ceramic material that is strong, durable, and has a natural-looking appearance.

The crown is secured in place with a small screw that is placed into the implant or abutment post. This screw is then covered by a small filling material, making it invisible to the naked eye.

One of the main benefits of using a screw-retained ceramic crown is that it allows for easy removal and replacement of the restoration if necessary. Additionally, the screw-retained design can help to minimize the risk of loosening or dislodging of the crown, as the screw provides an extra layer of stability.

Overall, screw-retained ceramic crowns can provide a long-lasting and aesthetically pleasing solution for individuals who are missing one or more teeth. It is important to consult with a dental professional to determine if this type of restoration is the best option for your specific dental needs.

Screw-retained monolithic zirconia crowns are a type of dental restoration made from a single block of zirconia material, which is a highly durable ceramic. The monolithic construction ensures that the crown consists of a solid piece of material, eliminating the risk of chipping or delamination seen in traditional porcelain-fused-to-metal crowns.

A small screw is used to secure the crown to the implant or abutment post, similar to screw-retained ceramic crowns. However, the exceptional strength of zirconia makes these crowns ideal for withstanding biting forces and resisting cracks or fractures.

Screw-retained monolithic zirconia crowns are particularly suitable for posterior teeth, such as molars and premolars, where strength and durability are crucial due to the demands of chewing.

Consulting with a dental professional is essential to determine if screw-retained monolithic zirconia crowns are the optimal choice for your specific dental requirements. They will assess your condition and provide personalized guidance to achieve the best outcome.

  1. Implant Placement: The first step involves the surgical placement of dental implants into the jawbone. This procedure is performed by an oral surgeon or a periodontist. The implants serve as artificial tooth roots and provide a stable foundation for the screw-retained crown.

  2. Healing Period: After implant placement, a healing period is necessary to allow osseointegration, which is the process of the implants fusing with the surrounding bone. This period typically ranges from a few months to several months, depending on the individual case.

  3. Abutment Placement: Once the implants have integrated with the bone, the next step is to attach abutments to the implants. Abutments are connector pieces that protrude above the gumline and serve as the attachment point for the screw-retained crown. The abutments can be prefabricated or custom-made, depending on the case.

  4. Impression Taking: An impression or mold of the abutments and surrounding teeth is taken using dental putty or digital scanning. This impression is used to fabricate a precise fitting crown in the dental laboratory.

  5. Crown Fabrication: In the dental lab, the screw-retained crown is custom-designed and fabricated based on the impression. It is typically made from materials like zirconia or metal alloys for optimal strength and aesthetics.

  6. Crown Placement: Once the crown is ready, it is checked for fit, color, and aesthetics. The crown is then placed on the abutments, and a screw is used to secure it into position. The access hole for the screw is usually located on the occlusal (biting) surface of the crown.

  7. Final Adjustments: The dentist makes any necessary adjustments to ensure proper fit, bite, and aesthetics. The crown is checked for occlusal harmony with the opposing teeth and adjusted if needed.

  8. Finalizing the Restoration: Once the screw-retained crown is properly positioned and adjusted, the access hole is filled with a composite resin or other dental materials to seal it. This ensures a natural appearance and prevents the entry of bacteria or debris.

The placement of screw-retained crowns requires expertise and precision to ensure a successful and long-lasting restoration. It is performed by dental professionals experienced in implant dentistry and restorative procedures.

The longevity of screw-retained crowns can vary depending on several factors, including oral hygiene practices, overall oral health, bite forces, and maintenance. However, when properly cared for and maintained, screw-retained crowns can last for many years, and in some cases, even a lifetime.

Screw-retained crowns are designed to provide durability and stability. The screw connection between the crown and the implant or abutment offers a strong and secure attachment. Additionally, materials like zirconia or metal alloys used in the construction of screw-retained crowns are known for their strength and resistance to wear.

To maximize the lifespan of screw-retained crowns, it is essential to maintain good oral hygiene practices, including regular brushing, flossing, and routine dental check-ups. Avoiding habits such as teeth grinding or biting on hard objects can also help prevent premature wear or damage.

While screw-retained crowns are designed to be long-lasting, periodic maintenance and follow-up visits with your dental professional are important. They can assess the condition of the crown, ensure proper fit and function, and address any concerns or issues that may arise.

  1. Laboratory costs: The fabrication process for screw-retained crowns often involves additional steps and requires specialized equipment and materials. This can contribute to higher laboratory costs compared to cemented crowns.

  2. Time: Time-wise, the placement process for screw-retained crowns may be longer than that for cemented crowns due to the additional steps involved, such as the placement of the abutment post and screw.

  3. Complexity of Placement: The placement process for screw-retained crowns can be more intricate and time-consuming compared to cemented crowns. It requires precise positioning and secure attachment using screws, which may require more expertise and time from the dental professionals.

  4. Customization and Materials: Screw-retained crowns often require customization to fit the unique shape and alignment of the patient's dental implants. Additionally, the materials used for screw-retained crowns, such as zirconia or metal alloys, may be more expensive than those used for cemented crowns.

Screw-retained crowns offer advantages such as improved stability, retrievability, and long-term durability. These benefits come with an added cost to ensure the precise fit, functionality, and aesthetics of the crown.

The suitability of screw-retained crowns varies depending on several factors, including the patient's oral health, the location of the implant, and their aesthetic preferences.
