Comparison of Dental Implant, Dental Bridge, and Removable Denture Solutions

“Which tooth replacement option should I choose?” This is a common question among individuals facing tooth loss. Currently, the three most widely used solutions include dental implants, dental bridges, and removable dentures. Each method offers its own advantages and is suited to specific cases. Among them, dental implants are considered the most advanced. However, is this truly the optimal choice for everyone? In this article, we will compare dental implants with bridges and removable dentures to help you determine the most suitable option for your needs.

The growing demand for tooth replacement

Tooth loss not only affects one’s appearance but also has a significant impact on oral health and quality of life. Missing one or more teeth can impair chewing function, cause neighboring teeth to shift, and lead to bite misalignment. In particular, jawbone resorption after tooth loss can make the face appear sunken and aged. These consequences have led to a growing demand for effective tooth replacement.

Thanks to advancements in modern dentistry, patients now have multiple options to restore their missing teeth, including:

• Dental implants
• Dental bridges
• Removable dentures

Each method is suited to different needs and oral health conditions. Without a proper evaluation, choosing the wrong option may result in poor chewing performance, incompatibility with jaw structure, or the need for repeated replacements – all of which can cost time and money.

Moreover, each technique has its own requirements regarding oral health and bone condition. Therefore, comparing dental implants with other restorative methods is essential for achieving a long-lasting and functional result.

Three common tooth replacement methods

Dental Implants

What is a dental implant?

 A dental implant is a procedure that replaces a missing tooth by surgically placing a titanium post into the jawbone, serving as an artificial tooth root. Titanium is highly biocompatible, allowing the implant to fuse with the bone without triggering rejection.

Once the implant is placed, the surrounding bone gradually integrates with the post. After successful osseointegration, an abutment and a dental crown are attached to complete the restoration, providing the look, function, and durability of a natural tooth.

This mechanism not only restores chewing ability but also helps prevent bone loss and maintains jaw structure.

A complete dental implant consists of three main components:

• Implant post: The artificial root with a roughened or threaded surface to enhance bone integration.
• Abutment: A connector between the implant post and the crown, ensuring tight stability. Abutments may be made from titanium, precious metals, or zirconia for durability.
• Crown: The visible part of the tooth, custom-made to match the shape and color of natural teeth, usually crafted from porcelain or porcelain-fused-to-metal for aesthetics and strength.

Advantages and Disadvantages

Advantages

Dental implants are highly valued for their ability to fully restore both the function and appearance of missing teeth, along with supporting long-term oral health.

• Restores full chewing ability: Because the implant is anchored directly into the jawbone, it provides strength comparable to natural teeth, allowing patients to chew freely—something that removable dentures often fail to deliver.
• Prevents jawbone loss and facial sagging: After tooth loss, the jawbone can gradually deteriorate due to a lack of stimulation. Implants preserve bone density, preventing sunken cheeks and premature aging.
• Natural look and feel: Implant crowns are carefully crafted to match the natural tooth in shape and color. The gum tissue around the implant also conforms to the crown, creating a realistic gum line.
• Long lifespan: With proper care, implants can last a lifetime, making them a cost-effective long-term solution compared to bridges, which typically need replacement every 10-15 years.
• Preserves neighboring teeth: Unlike bridges that require adjacent teeth to be shaved down for support, implants are standalone structures and do not affect nearby natural teeth.

Disadvantages

Despite their many benefits, dental implants also come with a few drawbacks to consider:

• Higher cost: Due to advanced technology, high-quality materials, and complex procedures, implant treatments are more expensive than bridges or dentures. The cost for a single implant can range from VND 13,000,000 to 35,000,000.
• Longer treatment duration: Implant procedures cannot be completed in one visit. After placing the implant post, it typically takes 3–6 months for the bone to fully integrate before the crown can be attached. In cases requiring bone grafting, treatment time may be extended.
• Requires sufficient bone quality: Not everyone is a candidate for implants. If the jawbone is too weak or has significantly resorbed, a bone graft may be necessary, which adds time and cost.
• Highly technique-sensitive: Implant placement demands a high level of expertise. If performed incorrectly, complications such as failed osseointegration, nerve damage, or infection may occur.

Dental Implant Procedure

The dental implant process involves multiple stages and requires a high level of precision to ensure long-term success. It typically includes the following six steps:

Step 1: Examination and Treatment Planning
The dentist begins by examining your oral condition and taking X-rays or a Cone Beam CT scan to assess jawbone density. If the bone is too thin or weak, bone grafting may be required prior to implant placement. Based on the evaluation, the dentist will determine the optimal implant position and create a personalized treatment plan.

Step 2: Implant Placement
Before the procedure, local anesthesia is administered to ensure the patient is pain-free. The implant post is then surgically placed into the jawbone at the site of the missing tooth. This step is relatively quick, typically taking only 20–30 minutes per implant.

Step 3: Osseointegration (3–6 months)
After the implant is placed, a healing period is required for the bone to fuse with the implant. During this time, the bone grows around the post, ensuring long-term stability for the final restoration. A temporary crown may be provided if needed for aesthetic purposes.

Step 4: Abutment Placement
Once the implant has successfully integrated with the bone, the abutment — a small connector piece — is attached to the implant. This component links the implant to the dental crown. After placement, the surrounding gum tissue is allowed to heal before proceeding to the final step.

Step 5: Crown Placement
A custom-made crown is created based on impressions of the patient’s bite to ensure a precise fit and natural appearance. Once the crown is secured onto the abutment, the dental implant process is complete.

Step 6: Post-Procedure Care and Follow-Up
Patients should maintain excellent oral hygiene, avoid excessive chewing on the implant site during the initial phase, and attend regular check-ups to ensure the implant remains in good condition. With proper care, a dental implant can last a lifetime.

Who is suitable for a Dental Implant?

• Individuals missing one or more teeth: Implants can replace missing teeth without affecting adjacent natural teeth, while restoring both function and aesthetics.
• Patients with sufficient jawbone density: The jawbone must have enough volume and strength to support the implant. In cases of bone loss, bone grafting may be recommended prior to the procedure.
• Healthy individuals without serious medical conditions: Patients with uncontrolled diabetes, advanced cardiovascular disease, or bleeding disorders should be carefully evaluated before undergoing implant surgery.
• Those seeking a long-term solution: Dental implants are durable and can last a lifetime with proper care, making them ideal for individuals looking for a stable and permanent tooth replacement option.
• Adults aged 18 and over: Implant placement is most effective once jaw development is complete, typically around age 18 and older.

To determine whether you’re a suitable candidate for this treatment, it’s essential to consult with a qualified implant specialist for a thorough examination and personalized advice.

Dental Bridges

What is a dental bridge?

A dental bridge is a fixed restorative solution used to replace one or more missing teeth by anchoring to adjacent natural teeth. It consists of a connected row of porcelain crowns, in which the two outer crowns are permanently attached to prepared adjacent teeth, while the middle crown(s) fill the gap left by the missing tooth/teeth.

The principle behind a dental bridge is to create a stable connection between real and artificial teeth, thereby restoring chewing function and aesthetics. The bridge is bonded in place using specialized dental cement to ensure a secure fit that resists shifting. Since there are no artificial roots beneath the prosthetic teeth, chewing forces are distributed through the supporting teeth. Therefore, dental bridges are only recommended when the adjacent teeth are healthy and strong enough to bear the load.

Advantages and Disadvantages

Advantages

• Effectively restores chewing function: A dental bridge is structurally strong and effectively fills the gap caused by tooth loss. The firm attachment to abutment teeth allows for comfortable chewing, minimizing discomfort when consuming tough or hard foods.
• Enhances smile aesthetics: Porcelain crowns closely mimic the color and shape of natural teeth, restoring facial harmony. With modern fabrication technology, bridges offer translucency and a natural shine, making them virtually indistinguishable from real teeth.
• Quick procedure: Unlike implants, which require surgery and healing time, bridges can typically be completed in just 2-3 dental visits, saving time for busy individuals.
• Cost-effective: Compared to dental implants, bridges are more affordable while still delivering effective restoration. This makes them an attractive option for those seeking a fast and economical solution.

Disadvantages

• Requires shaving down natural teeth: To anchor the bridge, dentists must file down the adjacent teeth. This removes natural enamel, potentially causing tooth sensitivity and weakening the structure over time.
• Does not prevent jawbone loss: Since a bridge only replaces the crown portion and not the root, it cannot stimulate the jawbone like a natural tooth. Over time, bone loss at the missing tooth site may occur, potentially affecting facial aesthetics.
• Durability depends on abutment teeth: The bridge’s longevity relies heavily on the health of the supporting teeth. If these teeth weaken due to disease or trauma, the bridge may loosen or fail.
• More difficult to clean than natural teeth: Because the bridge is fixed to neighboring teeth, cleaning underneath it can be challenging. If not properly maintained, food debris can become trapped, increasing the risk of gum disease or decay.
• Limited lifespan: On average, a dental bridge lasts 7-15 years, depending on the material and care. It may need to be replaced to maintain proper function and aesthetics.

Tooth reduction for bridge placement

During bridge placement, the dentist will reduce the size of the two teeth adjacent to the missing tooth. This creates enough space for the crowns to fit snugly and ensures the bridge can withstand chewing forces.

The amount of enamel removed depends on the dental condition and type of bridge. Typically, about 1–1.5mm of enamel is shaved off to ensure a proper fit without affecting the bite. Regardless of how much is removed, the enamel is lost permanently, which may increase sensitivity and risk of damage if not properly cared for.

As a result, dentists thoroughly assess the health of the supporting teeth beforehand. Only teeth that are strong and free from decay, pulpitis, or periodontal disease are considered suitable. If the neighboring teeth are too weak, dental implants may be recommended as an alternative to avoid compromising natural teeth.

Who should and shouldn’t get a dental bridge

Recommended for:

• Patients missing one or a few adjacent teeth: If healthy teeth are present on both sides of the gap, a bridge can effectively restore both function and appearance.
• Patients with minimal jawbone loss: Since bridges don’t include artificial roots, they’re best suited for cases where the underlying bone is still relatively intact.
• Those who need a quick solution: The bridge procedure can be completed in just 3-5 days, making it faster than implant placement.

Not recommended for:

• Patients without strong supporting teeth: If the adjacent teeth are weak, loose, or have undergone root canal treatment, they may not be able to adequately support a bridge.
• Cases of significant bone loss: In long-term tooth loss, jawbone resorption can cause gum recession under the bridge, affecting aesthetics and hygiene.
• Those unwilling to have adjacent teeth reduced: Since bridge placement requires enamel removal from healthy teeth, it may not be ideal for patients who want to preserve natural tooth structure. Dental implants may be a better option in such cases.
• Patients with advanced periodontal disease: If the supporting teeth are compromised by gum disease, they won’t be able to adequately hold the bridge, and the condition may worsen over time.

Removable Dentures

What are removable dentures?

Removable dentures are a type of dental restoration used to replace missing teeth by using an acrylic or metal base to hold artificial teeth in place. As the name suggests, they can be easily removed for daily cleaning. This method is especially suitable for individuals who have lost many or all of their teeth but are unable or unwilling to undergo bridgework or dental implants.

There are two main types of removable dentures:

• Full dentures: Designed for those who have lost all teeth in either the upper or lower jaw. These dentures consist of an acrylic base that fits snugly against the gums, with artificial teeth made from either acrylic or porcelain to restore appearance and chewing function.
• Partial dentures: Suitable for those who are missing several teeth but still have some healthy natural teeth. These dentures may be made from acrylic alone or combined with a metal framework for added durability. Metal clasps or attachments anchor the denture to the remaining teeth, providing better stability during use.

Advantages and Disadvantages

Advantages

• Cost-effective: This is currently the most affordable tooth replacement option, making it accessible to a wide range of patients.
• Non-invasive to natural teeth: Unlike dental bridges (which require trimming adjacent teeth) or implants (which involve surgery), removable dentures do not impact existing teeth or jawbone structure, minimizing the risk of oral injury.
• Easy to adjust or replace: As jawbone structure changes or more teeth are lost, dentures can be modified or replaced without complex procedures.
• Simple to clean: Because they are removable, these dentures can be cleaned thoroughly, reducing the risk of plaque buildup and gum disease.

Disadvantages

• Less stability: Removable dentures are held in place by suction (for full dentures) or metal clasps (for partial dentures). Over time, they may become loose, causing discomfort or falling out while eating or speaking.
• Reduced chewing efficiency: Without natural tooth roots, removable dentures only partially restore chewing ability. Hard or chewy foods can be difficult to manage, requiring dietary changes.
• Bone loss over time: Since dentures lack tooth roots to stimulate the jawbone, bone resorption gradually occurs. This can lead to a sunken facial appearance and dentures that no longer fit well, necessitating periodic replacement or adjustment.
• Initial discomfort and gum irritation: New denture wearers often experience soreness, a bulky sensation, or excessive saliva. While most adapt within weeks, some may experience prolonged irritation or even gum ulcers.

How removable dentures work

Removable dentures function by adhering to the gums and jawbone, using existing teeth (if any) for additional support and stabilization. Their mechanism of action varies depending on the type:

Full dentures:
These are prescribed when all teeth in one or both jaws are missing. They are made from an acrylic base with artificial teeth attached. Their adhesion relies on:

• Suction between the base and oral tissues: When properly positioned, a thin layer of saliva between the denture base and the gums creates a vacuum effect, helping the denture stay in place.
• Snug-fitting design: The base must be carefully shaped to match the patient’s dental arch, especially around the ridge and palate, to maximize suction.
• Denture adhesive (optional): Some individuals may use denture adhesives for added security.

Partial dentures:
Used when some natural teeth remain, partial dentures consist of an acrylic or metal base with prosthetic teeth, plus attachments that secure the denture to natural teeth. Their function relies on:

• Clasps or connectors: These secure the denture to natural teeth, reducing slippage during eating.
• Distribution of chewing forces: Forces are not only exerted on the gums but also transferred to the remaining teeth, helping reduce pressure on the jawbone.
• Greater stability than full dentures: Thanks to tooth anchorage, partial dentures shift less during use and may help slow bone loss compared to full dentures.

Who is suitable for removable dentures?

Removable dentures are a traditional tooth replacement method suitable for a wide range of people. Ideal candidates include:

• People missing many or all teeth: Partial dentures are recommended for those with multiple missing teeth and remaining healthy teeth to support the appliance. Full dentures are suitable for patients with complete tooth loss, restoring both function and appearance.
• Individuals with severe bone loss who can’t receive implants: Long-term tooth loss can lead to significant bone resorption, making implant placement difficult. Removable dentures don’t require bone grafting, making them a practical alternative.
• Elderly individuals or those unfit for surgery: Implant placement involves surgery and healing time. For seniors or those with chronic conditions like diabetes or heart disease, the risks may be too high. Removable dentures offer a non-surgical solution to regain chewing function.
• Patients needing a temporary solution: Dentures can be used as a short-term option while waiting for a more permanent restoration, such as dental implants. This is especially helpful for patients who are not yet ready financially or emotionally for fixed solutions.
• Budget-conscious individuals: Compared to implants and bridges, removable dentures are significantly less expensive, making them ideal for those seeking functional and aesthetic restoration without high costs.

Which method should you choose?

1. Recently lost teeth

For individuals who have recently lost teeth, the jawbone is still intact with little to no bone loss. This is the ideal time to choose an optimal restoration method to maintain jaw structure and ensure chewing function:

• Dental Implant: This is the best option as it directly replaces the lost tooth root and helps prevent bone loss. Implant placement at this stage is usually faster and more effective because the jawbone has not yet deteriorated.
• Dental Bridge: If the adjacent teeth are still strong, a dental bridge offers a quicker, less invasive alternative to implants. However, it does require trimming healthy teeth to serve as abutments.

2. Long-term tooth loss with bone resorption

When a tooth has been missing for a long time, bone resorption and gum recession can occur, making restoration more complex. Choosing the right method depends on the severity of bone loss and overall health condition:

• Dental Implant (may require bone graft): If significant bone loss is present, bone grafting or sinus lift may be necessary before placing an implant. Although this process takes longer, implants remain the most durable solution, helping preserve bone density and enhance facial aesthetics.
• Removable Denture: In cases of severe bone loss where bone grafting is not feasible, a full denture becomes a more practical solution.

3. Elderly or individuals with poor health

For elderly patients or those with underlying health conditions such as diabetes, heart disease, or osteoporosis, the jawbone may be resorbed, and surgery may pose greater risks:

• Removable Denture: This is the most common choice for elderly patients because it does not require surgery, has a lower cost, and can replace multiple teeth at once.
• Dental Bridge: If the adjacent teeth are still healthy, a dental bridge could be a suitable option that offers better chewing ability than removable dentures.

4. Need for quick and affordable restoration

For those seeking a fast and budget-friendly solution without prioritizing long-term bone preservation:

• Dental Bridge: A quicker method that can be completed within 3–5 days and costs less than implants.
• Removable Denture: Ideal for minimizing expenses or as a temporary solution before opting for bridges or implants.

Are Dental Implants the best option?

Dental implants closely replicate the natural structure of a tooth, with a titanium post acting as the root, integrating with the jawbone to maintain bone density.

According to a study published in the Journal of Clinical Periodontology, dental implants have a success rate of 95-98% within 10 years when performed with proper technique and care. This outperforms bridges and removable dentures, which may contribute to bone loss and reduced chewing function over time.

Implants are considered the most optimal solution for patients who meet the health and financial criteria. However, selecting the right method should take into account your oral health condition, overall health, and budget. For example, if you have adjacent healthy teeth and want a more affordable option, a dental bridge may be the better choice.

Conversely, for full-mouth restoration, implant-supported dentures may be more cost-effective and functional than placing individual implants.
