Screw-Retained Restorations

Oceanic Dental Laboratory offers exceptional clinical performance and affordability. Our implant restorations, including screw-retained crowns and implant-supported prosthetics, ensure a passive fit, which reduces crestal bone loss and enhances the esthetic zone.

Premium Screw-Retained Implants in Australia

At Oceanic, our screw-retained restorations may be crafted onto multi unit abutments or directly on the implant. These restorations are vital for full prosthetic replacements, including implant-supported fixed dental prostheses and single implants. We use various materials such as:

  • PFM (Porcelain Fused to Metal) with a titanium base or custom abutment
  • Zirconia with a titanium base or custom abutment
  • Full Metal Crown with a titanium base or custom abutment
  • Emax® with a titanium base or custom abutment
  • All-on-4® Nobel Biocare Solutions
  • All-on x solutions

Advantages of Screw-retained Implant Crowns

  • Ease of Retrieval: Allows for straightforward hygiene practices, maintenance, and replacement of the crown.
  • Better Retention in Limited Spaces: Offers improved retention in cases where an abutment lacks adequate height and surface area for a cemented crown.
  • Improved Hygiene: They are more conducive to maintaining healthy gingiva during the interim phase before the final crown is ready.
  • Aesthetic Options: Advancements like angulated screw channel solutions enable placement of the screw channel which is more aesthetically pleasing.
  • Ideal for Bridges and Cantilevers: Demonstrates greater durability and efficacy in bridge or long-span applications compared to cemented restorations.

Potential Limitations and Considerations

  • Restricted Access for Implant Drivers: Especially challenging in the posterior for tightening crowns.
  • Loosening of Screws Over Time: May necessitate more frequent and involved maintenance.

Planning the Placement of a Screw-retained Crown

Prior planning before installation is crucial. The proper placement of the implant is important to ensure screw access is through the central fossa in molars, or in the palatal side in anterior crowns. While this is typically straightforward in the posterior, anterior implants may present challenges, especially if the screw access hole needs to exit palatally.

FAQ

What are screw-retained Dental Restorations?

Screw-retained dental restorations are prosthetics attached either to an abutment or directly to a dental implant. They are used in full prosthetic replacements, including implant-supported fixed dental prostheses. Materials used include PFM, Zirconia, Full Metal Crown, Emax®,Titanium bases, All-on-4® Nobel Biocare solutions & All-on-X solutions.

How do aesthetics differ between screw-retained and cement-retained Implants?

Screw-retained implants often offer options with increased aesthetics, such as angulated screw channel solutions that enable better screw channel placement. In contrast, cement-retained implants may be preferred for aesthetics at the gingival margins, especially in anterior teeth.

How does the choice between Screw-Retained and Cement-Retained affect Implant Longevity?

The choice between screw and cement-retained implants can impact long-term outcomes. These generally allow for easier retrievability and maintenance, which may contribute to their longevity. However, the final decision should always consider factors like occlusal forces, positioning, and patient-specific needs and health conditions.

What is Peri-implantitis and How Does Implant Choice Affect It?

Peri-implantitis is an inflammatory condition affecting the tissues around dental implants. The choice between screw and cement-retained implants may impact the risk of peri-implantitis. Some studies suggest that residual cement from cement-retained implants can contribute to this condition.

How do Screw-Retained Implants Perform in Cases of Limited Bone Density?

Comprehensive planning and assessment are important in patients with limited bone density. There may be additional requirements to this type of procedure such as bone grafting before installation. We provide custom solutions and recommendations based on individual patient needs.
