Dental Screws: Materials, Placement & Longevity Explained

In the field of dentistry, dental implant screws have become an advanced tooth restoration technology and are increasingly the preferred choice for patients with missing teeth. Implants not only restore dental function but also achieve an aesthetic and comfort level that closely resembles natural teeth. They serve as the foundation for implant stability and are the key connection between the artificial tooth root and the upper crown.

As a core component of dental implant technology, dental implant screws require careful consideration regarding material selection, implantation procedures, and factors affecting their longevity. Through this article, we aim to provide readers with a comprehensive and in-depth understanding of implant screws, enabling them to make more informed decisions when needed.

What Are Dental Screws?

In dentistry, tandheelkundige schroeven, commonly referred to as implants or dental implants, are a crucial component of modern restorative dentistry. These specially designed screw-like structures are typically made from highly biocompatible materials such as pure titanium or titanium alloys. The primary function of dental screws is to provide a stable foundation for patients with missing teeth, securing artificial crowns or dentures to restore and rebuild dental function.

The Importance of Dental Screws in Modern Dentistry

• Stable Support: Dental screws are surgically implanted into the patient’s jawbone, integrating with the bone tissue to provide a firm foundation for the artificial crown or denture. This stability ensures that the restored teeth can function properly for activities such as chewing and speaking.
• Stabiliteit op lange termijn: Since dental screws biologically integrate with the surrounding bone, they offer excellent long-term stability. Once successfully implanted and fused with the bone, patients can rely on their restored teeth for years without concerns about loosening or falling out.
• Aesthetic and Comfort Benefits: The design of dental screws allows for restorations that closely resemble natural teeth in both appearance and comfort. They seamlessly blend into the patient’s oral environment, enhancing aesthetics while improving overall quality of life.

What Materials Are Dental Screws Made Of?

Dental screws, also known as implants, are essential components in modern restorative dentistry. They are made from high-performance materials designed to meet the complex demands of the oral environment. Below are the most common dental screw materials and their characteristics:

Titanium

• Strength and Biocompatibility: Titanium is considered the “gold standard” for dental implant materials. It offers exceptional strength, allowing it to withstand various biting forces while maintaining excellent biocompatibility. This means titanium implants integrate well with human bone tissue, reducing the risk of rejection and increasing implant success rates.
• Voordelen: Titanium implants are lightweight, corrosion-resistant, and do not interfere with medical imaging techniques such as MRI (Magnetic Resonance Imaging).

Titaniumlegering

• Enhanced Durability and Flexibility: Titanium alloys are composite materials created by adding other metals (such as aluminum and vanadium) to pure titanium. These alloying elements enhance mechanical properties such as strength and wear resistance while increasing flexibility, making them more adaptable to different oral conditions.
• Voordelen: Titanium alloy implants are ideal for patients with high bite force or complex oral conditions, providing a longer lifespan and more stable restoration.

Zirconia Screws

• Aesthetic and Metal-Free Alternative: Zirconia is a high-strength, highly stable ceramic material that has gained popularity in dentistry in recent years. Zirconia screws offer excellent aesthetics, as their color closely resembles natural teeth. Additionally, they are metal-free, eliminating concerns about metal allergies and corrosion inside the oral cavity.
• Voordelen: Zirconia screws are ideal for patients who prioritize aesthetics, such as those requiring front-tooth restorations. Their outstanding physical and chemical properties also ensure long-term stability and durability.

The choice of dental screw materials varies, with each offering unique advantages suited to specific situations. Titanium and titanium alloys dominate the market due to their exceptional strength and biocompatibility, while zirconia screws are a preferred option for patients seeking a metal-free, highly aesthetic solution. When selecting implant materials, dentists carefully evaluate each patient’s individual needs to ensure a successful procedure and long-term oral health.

Primary Uses of Dental Screws

dental implant screws are the core components of dental implant technology. They are precisely embedded into the jawbone, serving as a solid foundation for artificial teeth. The brilliance of this innovative design lies in its ability to secure dental crowns firmly in place without causing damage to adjacent natural teeth.

The remarkable feature of dental screws is their ability to integrate tightly with the jawbone through a process called osseo-integratie. This biological fusion provides an exceptionally stable base for the implant, allowing the artificial tooth to be firmly anchored within the oral cavity.

The ultimate mission of dental screws is to replicate the function of natural tooth roots, absorbing and distributing the forces generated during chewing. Like loyal guardians of the jawbone, they effectively prevent bone loss that may occur due to tooth loss, thereby preserving the integrity and health of the jawbone.

Where Are Dental Screws Placed?

In dental implant surgery, dental implant screws are precisely positioned within the patient’s jawbone. Their exact placement depends on the individual’s oral condition, the location of missing teeth, and the treatment plan. Below is a detailed explanation of dental screw placement locations:

1. Maxilla (Upper Jaw)

• Alveolar Ridge Crest: In the upper jaw, dental screws are typically placed at or near the alveolar ridge crest. This is the prominent bony structure left after tooth extraction, providing a stable foundation for the implant.
• Palatal Bone Plate: In certain cases, such as in the anterior maxillary region, dental screws may also be placed in the palatal bone plate. This provides additional anchorage support and helps adjust the vertical alignment of the teeth.

2. Mandible (Lower Jaw)

• Alveolar Ridge Crest: Similar to the upper jaw, the alveolar ridge crest in the lower jaw is a common placement site for implants.
• Buccal Bone Plate: In some cases, dental screws may be positioned in the buccal bone plate, particularly when additional anchorage is needed or to address mandibular retrusion.
• External Oblique Ridge: This is a relatively safe and stable area of the lower jaw, suitable for treatment plans involving the retraction of lower teeth or the distalization of molars.

3. Special Placement Areas

Zygomatic-Alveolar Ridge: In complex implant cases where bone mass in the posterior maxilla is insufficient, dental screws may be placed in the zygomatic-alveolar ridge. This technique requires advanced surgical skills and precision.

Are Dental Screws Painful?

For many patients, undergoing a dental procedure may cause some level of pain and discomfort. However, with advancements in modern medical technology and effective pain management strategies, most patients can go through the process smoothly and recover quickly. Below are detailed recommendations on managing pain and promoting recovery during and after the procedure.

During the Procedure

• Plaatselijke verdoving: Before performing the procedure, the dentist will administer a local anesthetic to numb the surgical area. This temporarily blocks nerve signals, ensuring that patients experience little to no pain during the procedure.
• Preemptive Pain Management: Studies have shown that taking nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, before the procedure can effectively reduce postoperative pain. These medications work by inhibiting inflammatory mediators, reducing tissue damage and stress responses caused by the surgery.
• Relaxation Techniques: While it’s natural to feel anxious before a procedure, staying relaxed can help minimize the perception of pain. Patients can use deep breathing exercises, listen to music, or practice other relaxation techniques to ease anxiety.
