What are the Limitations of Dental Implants

by Dental-Pedia
Dental implants replace the root of a lost tooth and are generally very safe.


Dental implants are suitable for most people. Whether you are missing one tooth, several teeth or all your teeth, you can receive dental implants to restore optimal functionality and aesthetics. Dental implants bond to the surrounding bone tissue through a process called osseointegration, serving as a replacement for your complete tooth structures. In general, there are no major limitations with dental implants.

In rare cases, however, a patient may be deemed unsuitable for dental implants because they have underlying conditions that prevent healing, there is too little bone tissue or there is a possibility of an allergic reaction to titanium implants. However, these are extremely rare cases and most of them can be overcome. This article looks at the limitations of dental implants and how they can be overcome using different methods.



The 3 most Common Dental Implant Limitations and How to Overcome Them

The 3 most Common Dental Implant Limitations and How to Overcome Them

#1. Impaired Healing

After you receive dental implants, you have to go through a healing process called osseointegration. Your jawbone gradually heals around the implant and anchors it like a natural root, making it part of your anatomy. However, some people have an impaired healing ability that delays the osseointegration process or prevents sufficient bone growth to anchor the implant. Therefore, people with impaired healing ability may not be ideal candidates for dental implants.

Dental Implants: Certain medications can impair the ability to heal

Solution: Temporarily discontinue certain medicines

Most people suffer from an impaired ability to heal due to certain medications known as bisphosphonates, such as alendronic acid. These drugs slow down the body's natural healing processes. In addition, healing can also be affected by excessive smoking. To get around this problem, your dentist may ask you to stop smoking and stop taking certain medications a few months before the procedure. You need to be completely transparent with your dentist about your lifestyle and the medications you are taking.

#2. Insufficient Jaw Bone

Dental implants need to be connected to your jawbone through a process called osseointegration. Once the implant is drilled into the jawbone, your body gradually heals around the implant and roots it into place. The implant can only be anchored in the jawbone if you have enough bone tissue. If you do not have enough bone tissue, there is a high risk that the implant will fail, i.e. that the implant will loosen due to lack of support and eventually have to be removed.

The loss of bone tissue occurs gradually after tooth loss. The jawbone usually supports the tooth structure and provides it with a growth impulse. When you suffer tooth loss, the underlying jawbone no longer has a growth impulse, so it gradually disintegrates. If you don't get a dental implant soon after tooth loss, your jawbone tissue will continue to break down, which is a potential challenge if you decide to get implants a few years later.

Solution: Bone grafting for augmentation

A bone graft is the ideal solution for insufficient jawbone tissue. The oral surgeon takes the bone replacement material from other parts of your body, from another person or from a donor bank. The bone replacement material is implanted under the gum flap of the missing tooth, promoting natural bone regeneration. Over the course of several months, your bone tissue will grow back to replace the bone substitute material and make you a suitable candidate for dental implants.


#3. Titanium Allergies

Some patients are allergic to metallic components, such as titanium. Patients with a titanium allergy can develop severe symptoms, such as swelling, redness, irritation and gradual failure of the implant. In addition, allergic reactions can occur several weeks, months or even years after implant surgery, making it extremely difficult to find the cause of your symptoms. Dental surgeons usually perform allergy tests to determine whether patients can undergo the procedure.

Solution: Zirconia (ceramic) dental implants

Zirconia (ceramic) implants are non-metallic, so they do not have the same allergies as titanium or metal. They also carry a negligible risk of corrosion, have better biocompatibility and are considered safer than titanium implants. Although ceramic implants are relatively new, recent studies have shown comparable success rates to titanium implants. So if you are concerned about a titanium allergy, you may consider ceramic implants instead.
