Dental implant screw
Discover how a dental implant screw works, what it is made of, and how it integrates with the jawbone to support the crown and restore tooth function.
Dental implants have become a widely used solution for replacing missing teeth and restoring chewing function and smile aesthetics. The dental implant screw, more accurately referred to as the implant fixture, is one of the essential components of this treatment because it is anchored within the jawbone to support the replacement tooth.
However, certain changes after implant placement may cause concern, such as exposure of part of the implant through the gum tissue or implant mobility. These changes often raise questions about their causes and whether they may affect the success of treatment.
In this article, we will explain what a dental implant screw is, the main types of dental implant fixtures, whether an implant can become loose or fail, the cost of dental implants, possible causes of implant exposure or mobility, and the treatment options available when implant components become loose or displaced.
What Is a Dental Implant Screw?
A dental implant screw, clinically known as a dental implant fixture, is a small component designed to function as an artificial tooth root.
It is surgically placed within the jawbone to replace the root of a missing tooth. Once the implant has achieved adequate healing and osseointegration, a prosthetic abutment and dental crown are attached to restore the appearance and function of the missing tooth.
Dental implant fixtures are commonly manufactured from titanium or other biocompatible materials that are suitable for implantation within the body.
The implant surface allows bone to heal around and establish direct contact with the fixture, creating a stable foundation for the abutment and final prosthetic restoration.
At Dr. Ammar Clinics for Dental Care, Cosmetic Dentistry, and Implant Dentistry, we carefully evaluate the jawbone and oral condition before selecting an implant system appropriate for each case.

Types of Dental Implant Screws
Different types of dental implant fixtures are available to accommodate variations in jawbone anatomy, missing-tooth locations, and individual treatment requirements.
Some patients may be suitable for conventional implant placement, while others may require specific implant designs or surgical approaches because of limited bone volume or anatomical considerations.
Common implant approaches include:
Conventional Dental Implants
Conventional implants are commonly used when there is adequate jawbone volume and density to achieve appropriate implant stability.
Short Dental Implants
Short implants may be considered in selected patients with limited vertical bone height.
In certain clinical situations, they may reduce or avoid the need for more extensive bone augmentation procedures, depending on bone anatomy and the overall treatment plan.
Tilted Dental Implants
Tilted implants are placed at a carefully planned angle to avoid anatomical structures or areas with insufficient bone.
They may be incorporated into specific full-arch or complex implant rehabilitation protocols.
Zygomatic Implants
Zygomatic implants are used in selected cases of severe maxillary bone loss.
Instead of relying primarily on the alveolar bone of the upper jaw, these longer implants gain anchorage from the zygomatic bone.
Because of their complexity, zygomatic implants require advanced surgical experience and careful diagnostic planning.
Immediate Implant Placement
Immediate implant placement refers to placing the implant into the extraction socket at the same appointment as tooth extraction.
This approach can be considered in appropriately selected patients, but it is not suitable for every case.
The selection of an appropriate implant design and treatment approach depends on clinical examination, dental imaging, available bone volume, implant site anatomy, and restorative requirements.
Can a Dental Implant Screw Fall Out?
A dental implant may become mobile or fail in some situations, but apparent movement does not always mean that the implant fixture itself has failed.
The problem may involve:
The implant fixture.
The abutment.
The prosthetic screw.
The dental crown.
For this reason, it is important to identify which component is actually moving.
Possible warning signs include:
Mobility of the implant-supported tooth: A sensation that the restoration moves during chewing.
Persistent pain: Pain that continues or increases, especially during biting or chewing.
Swollen or red gums: Inflammation around the implant site.
Discharge or pus: Possible signs of infection around the implant.
Changes in the bite: The implant-supported tooth may feel different when the teeth come together.
Exposure of implant components: Part of the implant, abutment, or other component may become visible through the gum tissue.
Any unusual mobility, persistent pain, swelling, or discharge should be assessed by a dentist.
Causes of Dental Implant Failure
Dental implant failure can occur for several reasons.
Some factors interfere with the biological integration between the implant and jawbone, while others involve infection, insufficient bone support, excessive loading, or technical complications.
Potential causes include:
Failure of Osseointegration
In some cases, adequate bone-to-implant integration may not develop.
Insufficient osseointegration can compromise implant stability and may lead to implant mobility or failure.
Peri-Implant Infection
Inflammation or infection affecting the tissues surrounding the implant can contribute to bone loss and compromise long-term implant support.
Poor plaque control and untreated peri-implant inflammation may increase this risk.
Premature or Excessive Loading
Applying excessive forces to an implant before adequate healing has occurred may interfere with implant stability.
The timing of prosthetic loading therefore depends on factors such as bone quality, primary stability, implant design, and the overall treatment protocol.
Insufficient Jawbone
Inadequate bone volume or density may affect the ability to achieve appropriate implant stability.
Some patients may therefore require bone grafting or other augmentation procedures before or during implant treatment.
Certain Medical Conditions
Poorly controlled systemic conditions, such as uncontrolled diabetes, may interfere with healing and may increase the risk of implant-related complications.
Medical history should therefore be reviewed before implant surgery.
Surgical or Technical Factors
Incorrect implant positioning, inappropriate angulation, or other surgical and prosthetic complications can affect implant function and long-term stability.
Poor Postoperative Care
Failure to follow oral hygiene instructions, medication recommendations, and professional follow-up may increase the risk of complications.
It is also important to understand that movement of an implant-supported tooth does not necessarily mean that the implant fixture has become loose.
In some cases, the abutment screw may loosen while the implant remains firmly osseointegrated within the bone.
Why Is My Dental Implant Screw Showing Through the Gum?
Some patients may notice that part of an implant or implant component has become visible through the gum tissue.
This may occur because of:
Gingival recession.
Loss of soft-tissue coverage.
Bone loss around the implant.
Exposure of an abutment or healing component.
A normal stage of treatment in which a healing abutment is intentionally visible.
Therefore, seeing part of an implant component does not automatically mean that treatment has failed.
If you notice implant exposure, you should:
Contact your dentist for an examination.
Avoid touching or manipulating the exposed component.
Maintain gentle oral hygiene according to your dentist's instructions.
Attend scheduled follow-up appointments.
Seek prompt assessment if pain, swelling, bleeding, or discharge develops.
Early evaluation can help determine whether the visible structure is a normal treatment component or a sign of a complication.
Dental Implant Screw Cost
The cost of dental implant treatment varies according to the manufacturer, implant system, prosthetic components, jawbone condition, and any additional procedures required.
In Egypt, the cost of replacing a single tooth with a dental implant may range from approximately EGP 12,000 to EGP 25,000, according to the clinic's current pricing.
The final cost may vary depending on:
Implant brand and system.
Number of missing teeth.
Periodontal condition.
Condition of adjacent teeth.
Final crown material.
Diagnostic imaging.
Need for bone grafting.
Additional surgical procedures.
Follow-up requirements.
To determine the cost appropriate for your individual condition, a clinical examination and treatment plan are required.
What Does a Dental Implant Screw Look Like?
A dental implant fixture usually has a screw-shaped, cylindrical, or tapered design.
The outer surface contains threads that engage the jawbone and contribute to primary stability during implant placement.
The exact implant shape varies according to:
Implant system.
Diameter.
Length.
Thread geometry.
Implant site.
Bone density and volume.
Prosthetic requirements.
A conventional implant-supported tooth usually involves three main components:
Implant fixture:
The component placed inside the jawbone that functions as an artificial tooth root.Abutment:
The connecting component between the implant fixture and the prosthetic restoration.Dental crown:
The visible restoration designed to reproduce the appearance and function of the missing tooth.
Different implant systems use different connection designs, implant shapes, and restorative components.
Therefore, the choice of implant fixture is based on biological and prosthetic requirements rather than appearance alone.
What Are the Best Dental Implant Systems in Egypt?
Many dental implant systems are available in Egypt, differing in manufacturer, implant design, surface characteristics, restorative components, and cost.
Some internationally recognized implant systems include:
Straumann
Nobel Biocare
Osstem
Each system has different design characteristics and restorative options.
However, choosing the most appropriate dental implant should not be based solely on the brand name.
Important factors include:
Jawbone density and volume.
Periodontal health.
Implant position.
Available restorative space.
Type of final crown or prosthesis.
The patient's general health.
The clinician's experience with the selected implant system.
At Dr. Ammar Clinics, we evaluate the jawbone and oral condition before selecting an implant system that corresponds to each patient's clinical requirements.
Treatment for a Loose or Failed Dental Implant Screw
Treatment depends on identifying which implant component has become loose or failed and determining the underlying cause.
The problem may involve:
A loose abutment screw.
A mobile crown.
A damaged prosthetic component.
Peri-implant inflammation.
Failure of the implant fixture to integrate with the bone.
Possible treatments include:
Retightening or replacing the abutment screw when the implant fixture itself remains stable.
Repairing or replacing the crown if the problem is limited to the prosthetic restoration.
Treating peri-implant inflammation or infection when the surrounding tissues are affected.
Removing the implant fixture if osseointegration has failed or implant stability cannot be restored.
Considering re-implantation after appropriate healing and reassessment, when clinically suitable.
Patients should never attempt to reposition or tighten implant components themselves.
If any component becomes loose or falls out:
Keep the component if possible.
Avoid chewing on the affected side.
Do not attempt to reinsert it.
Contact your dentist promptly.
