Dentures have provided a straightforward solution to tooth loss for decades. You can achieve a full, customized smile in just a few dental appointments. However, dentures can become increasingly uncomfortable over time, often slipping and shifting as you eat or speak. What many patients don’t realize is that dentures can also cause bone resorption, making it more challenging to get implants without first receiving a dental bone graft in New York City.
Bone grafts promote the growth of new bone in areas that have deteriorated due to tooth loss, periodontal disease, or other infections. This procedure helps prevent facial sagging and an overall aged appearance. Grafts also serve as the essential first step in obtaining a more stable restoration, such as implant-supported dentures.
What Is Bone Resorption, and How Do Dentures Cause It?
Bone resorption is the biological process by which bone tissue breaks down and releases its minerals (primarily calcium and phosphate) into the bloodstream. In healthy individuals, new bone is built through a natural biological process called bone remodeling, which maintains bone strength and mineral balance.
Problems arise when bone isn’t rebuilt to replace what was lost. While this imbalance is common with aging, certain factors can accelerate the process, causing facial sagging in the mouth area and potentially putting any remaining natural teeth at risk. Tooth loss, for example, is a significant factor that can accelerate bone resorption.
When a tooth is extracted or lost and not replaced, the jawbone in that area no longer receives the necessary stimulation from chewing forces, leading to gradual bone deterioration. Jawbone loss is extremely common for denture wearers who have lost all or most of their teeth.
Additional ways that denture wear contributes to bone resorption include:
1. Chronic Mechanical Pressure
Constant pressure from the denture base especially with ill-fitting or worn dentures compresses the soft tissues and underlying bone. This leads to localized ischemia (restricted blood flow), which triggers bone remodeling and resorption in response to the stress.
2. Periodontal Disease
Denture-wearers often assume they don’t need to care for their mouth because they’ve already lost most of their teeth. However, they can still develop periodontal disease, an infection that leads to bone resorption without prompt treatment.
3. Tissue Irritation and Ulceration
Poorly adapted dentures can cause ulcers or trauma to the soft tissue. Chronic irritation can affect the underlying bone through inflammatory mediators, accelerating bone loss.
4. Lack of Regular Adjustments
As denture wear leads to bone resorption, it affects the precise fit of the dentures themselves. For this reason, dentists recommend periodic adjustments and relines.
Failure to maintain proper adjustments means dentures no longer fit the evolving ridge, creating a destructive cycle in which increased pressure points accelerate localized bone loss, making the fit even worse.
What Are Implant-Supported Dentures and How Do They Solve These Issues?
If you’re tired of shifting dentures, irritated gums, and the ongoing threat of bone resorption, implant-supported dentures are an advanced and effective alternative.
Unlike traditional dentures, these solutions use strategically placed dental implants to secure a fixed, stable prosthetic that won’t move as you eat or speak. Because implants anchor directly to your jawbone, they provide the strength of natural teeth while stimulating the bone tissue, effectively preventing further bone loss.
Implants are made of three components:
- Implant Fixture: A titanium or zirconia post surgically inserted into the jawbone. It acts as an artificial tooth root, anchoring the restoration and stimulating the jawbone.
- Abutment: A small connector piece placed on top of the implant fixture after healing to connect the implant to the final restoration (in this case, a full-arch denture).
- Restoration: The visible portion of the implant system.
The implant fixture’s material (titanium or zirconia) is biocompatible. This means it can integrate with your jawbone to achieve a solid, long-lasting grip through a process called osseointegration.
Bone Grafts: Making Implant Dentistry Possible Even After Years of Denture Wear
While implant-supported dentures offer significant benefits, they do require one critical element: sufficient bone density. Implants must integrate with the jawbone to function properly. This requirement might seem like an insurmountable obstacle for patients who have worn dentures for several years and experienced bone resorption.
Fortunately, it doesn’t have to be.
Modern procedures like bone grafts make it possible for patients with severe bone loss to become candidates for implants. A bone graft is a surgical procedure where bone or bone-substitute material is placed in the jaw to restore bone volume lost due to tooth loss, trauma, gum disease, or resorption.
The bone material can originate from your own body, processed animal bone, or synthetic materials. After placement, your body gradually replaces the graft with new, living bone through a process called guided bone regeneration (GBR), which typically takes 3 to 9 months depending on the individual case.
A bone graft provides several benefits:
- Rebuilds lost bone height and width
- Creates a stable foundation for dental implants
- Preserves the jaw structure and facial aesthetics
- Prevents sinus proximity or nerve exposure during implant placement
How Can I Know if Bone Grafts and Implant Dentistry Are an Option for Me?
Today’s advanced dental technology makes dental implants accessible to most patients. However, each case requires individual assessment. Graft success depends on several factors:
- The amount of existing bone
- The patient’s health status
- Good oral hygiene
Your dentist will use various advanced imaging tools to evaluate your situation and work with you to determine the best possible treatment approach.
Make Implant-Supported Dentures a Possibility with a Dental Bone Graft in New York City
Dentures may seem like the perfect solution initially. They provide a quick, effective, and relatively durable way to restore your complete smile, allowing you to eat, speak, and smile with confidence. However, as years pass and your bone structure changes, you may begin to experience the limitations that dentures present. In these situations, implant-supported prosthetics can be truly life-changing.
Implant-supported dentures offer a more secure dental restoration, eliminating shifting dentures, messy adhesives, and progressive bone loss. Ready to learn more? Dr. Geoffrey Rubinshtein is here to help. Contact us today for more information!
