Bone Grafting for Dental Implant: Tooth Talk Series by Dr. Victor Sun

In many situations, dental implants are becoming the first choice of treatment for replacing missing teeth. They can be more desirable than the alternative options of partial dentures or bridges.

A dental implant is a titanium metal post inserted into the jaw bone and it supports a post onto which a crown(tooth) is placed. In order for a dental implant to work, it has to be “osseointegrated” within the bone so that it is strong enough to support the tooth and the chewing forces. Therefore, it is important to ensure that there is sufficient volume of bone around a dental implant as it is the bone that provides the dental implant its strength and stability.

Generally speaking, 1 1⁄2 mm to 2 mm of bone is desirable around a dental implant. In terms of bone height, there should be enough bone so that the implant is completely surrounded by bone and the implant is a safe distance(minimum 2mm) away from anatomic structures such as the nerve in the lower jaw.

One of the consequences of tooth loss is bone loss. After a tooth is removed, there is no more stimulation on the jaw bone surrounding that lost tooth from the chewing force. Subsequently, the jaw bone will shrink away.

Therefore, for those who have suffered tooth loss for a long time and want dental implant therapy, a great majority of them will require bone grafting procedures in order to build up the jaw bone for dental implant placement.

There are several types of bone graft material that can be used to rebuild the jaw bone:

-Autograft: bone from the patient’s own body, usually taken from the chin or from the back of upper or lower jaw near the wisdom teeth. If substantial amount of bone is needed, the surgeon can harvest the bone from the patient’s hip, shin, rib, skull, etc.

-Allograft: bone from a genetically similar organism. Human cadaver bone from the bone bank falls in this category.

-Xenograft: bone from a genetically dissimilar organism. Bovine (cow) bone is a typical example of xenograft.

-Synthetic bone graft: man-made synthetic biocompatible material. Hydroxyapatite or tricalcium phosphate are examples of synthetic bone graft material.

-Growth factors: they are produced using DNA technology. They consist of either human growth factors or bone morphogenic protein-2 (BMP-2). They stimulate certain body cells to turn into bone. They can be used alone, such as BMP-2, or in conjunction with other bone graft material, to grow bone.

Generally speaking, it takes about 6 to 9 months for a bone graft to mature. The amount of time for the graft to heal depends on the type of grafting material used, the size of the bone defect, etc. The best time to place the implant is when the bone graft has become solid where there is sufficient healing but before it starts to shrink or resorb.

The success rate for bone grafting in the jaws is quite high. However, there is always the possibility that the bone graft can fail, even with using the patient’s own bone. Certain medical conditions, such as diabetes, increase the risk of bone graft failure. Smoking compromises healing and can lead to higher failure rate. If the bone graft fails, it can be removed and a second graft can be placed in most situations.

How Can I Get My Dentures to Stop Coming Loose?!

Standard

My dentures are loose! I can’t eat with them and I’m nervous to talk or smile for fear that they’ll fall out. Does this sound familiar? At Dr. Victor Sun’s practice, he has been helping patients stabilize their dentures for years with great success. How? With dental implants – the modern approach to stabilizing your smile.

What Are Dental Implants?

Dental implants are small metal artificial tooth roots that are placed under your gums, just like real teeth. Depending on your individual needs, Dr. Sun will come up with a treatment plan suitable for your dental needs. There are different types of implant overdentures to choose from; they provide varying degrees of support and stability all much better than conventional full bottom dentures that rely solely on suction.

Depending on your situation you might be a candidate for implants to  help stabilize your partial or full dentures on the top or the bottom!

Let’s talk specifics.

Locator Overdentures:  As few as two dental implants in the lower jaw can help stabilize a full bottom denture. The caps inside the denture snap onto the head of the implants. This connection provides the support and stability to the lower denture. The more implants placed, the more stable the denture becomes! Since part of the denture is still supported by the gum tissue, there is potential for gum irritation. To avoid this, Dr. Sun will check the denture to ensure there are no ongoing sore spots on your gum tissue. It’s important to schedule annual visits for this reason so that any reline adjustments can be made prior to irritation occurring.

Case Completed in 2017:

Problem: Remaining lower teeth in poor shape, no bone to support a full lower denture

Solution: Remove the remaining lower teeth, place 3 dental implants into the lower jaw at the time of teeth removal, wait for the healing to complete, secure the full lower denture onto the 3 implants

Result: Patient can eat/chew/talk without the fear of the lower denture falling out. Quality of life has improved tremendously!

 

Bar Overdentures: With more implants, such as four or five on the lower jaw, a metal bar can be fabricated to join the implants together. The full lower denture then snaps onto the bar, creating a very stable base. This option is more stable than the locator overdenture as it sits exclusively on the bar. That means less gum tissue issues because the denture doesn’t touch your gums at all.

Case Completed in 2003:

Problem: Lower denture rocking due to lack of bone support.

Solution: Five (5) Implants placed in lower jaw, joined together with bar to provide stability to the lower loose denture.

Result: Stable lower denture stays in place. Patient can eat, talk and smile without discomfort.

 

Mini-Implant Overdentures: Dental implants that are less than 3mm in diameter are called mini-implants. Mini-implants are an excellent option for patients who have undergone severe bone shrinkage. Due to their smaller size, mini-implants can be placed in areas with limited bone volume to help retain loose full bottom dentures. A minimum of four mini-implants in the lower jaw are required to support a full bottom denture. Again, the more implants placed, the more stable your denture will be.

It is important to know that just like a conventional full bottom denture, an implant supported full bottom denture still needs to be removed at night and soaked either in water, a half water/half listerine mixture, or in a dental cleanser. And be sure to brush your denture with a denture brush. A well cared for implant supported lower denture should provide you with years of a stable smile.

 

What if I don’t have dentures but my crown just won’t stay? Can implants help me?

Yes! Many times implants can be used to support a crown for just one tooth. Using an implant to help replace a missing molar can be an effective solution. Additionally, using an implant for the crown will help to prevent drifting of the adjacent and opposing teeth – meaning fewer issues in the long run.

Case Completed in 2018:

Problem: Tooth loss due to fracture of the natural tooth. Patient could not chew as well with a “hole” on the right side.

Solution: One implant-supported crown to replace the missing molar.

Result: Patient can chew much better on the right side and the new tooth prevents drifting of the adjacent and the opposing teeth.

Dr. Victor Sun Discusses Lower Denture Stabilization

Standard

Screen Shot 2015-01-11 at 2.18.38 PM

 

HEY DOC, I CAN’T EAT OR TALK WITH MY FULL BOTTOM DENTURE!
CAN YOU HELP ME!? (Part 1 of 2)

Out of all the treatment modalities in dentistry, complete or full lower dentures probably have the lowest success rate. Many people who have lost their bottom teeth, especially those with their bottom teeth removed a long time ago, and have to relegate to wearing full lower dentures, often complain of their  inability to  keep the dentures in place for proper eating, chewing and speech. They can’t enjoy their food anymore and it becomes a social embarrassment when their full lower dentures fall out of their mouths during eating or talking at social functions or at family gatherings!    

Why don’t they stay in?

Continual bone loss- After teeth are removed, human’s jaw bone will continue to shrink away in height and in width throughout the person’s lifetime. This phenomenon is due to the lack of stimulation to the jaw bone during eating and chewing through the teeth.  Unfortunately, the lower jaw bone shrinks  away much more rapidly than the upper jaw bone. Some research studies show that lower jaw bone can disappear up to 4X as fast as the upper jaw bone after teeth removal! The lack of lower jaw bone means the lack of suction to support a full bottom denture.

Presence of the tongue- Human’s tongue is one of the strongest muscles in the body and it can easily push on and dislodge the full bottom denture during eating and speech.

Limited surface area for denture support- A full upper denture can rely on the roof of the mouth for support and stability. The lower jaw is “U” shaped and it simply lacks the amount of surface area of bone that the upper jaw has for denture support.

What can be done?

Denture reline-  As the lower jaw bone shrinks away, a space will develop between the full lower denture and the lower jaw bone. As a result, the denture does not seat tightly on the jaw bone anymore and the denture becomes loose. By having a denture reline, new plastic denture material is added to the bottom of the denture so that the lower denture will again fit tightly on the lower jaw bone. However, if the patient has lost a substantial amount of bone, denture reline will not help much at all as there is still inadequate bone for the lower denture to grip onto.

Denture adhesives- There are many types of denture adhesives/glues available over-the-counter that people can purchase to help stabilize their full bottom dentures.  Again, just like denture reline, if there is inadequate bone, denture adhesives can only help marginally at best.    

Dental implants- For those who have a really tough time keeping their full lower dentures in place, dental implants most likely will be the best solution to their problem.  As I have discussed in my previous article, dental implants are  pegs/screws made of titanium alloy that are inserted into the lower jaw bone to help stabilize and support the full lower denture. The more implants that the patient chooses to have, the more stable the denture will be, taking into consideration the anatomical boundary for the placement of the implants. After the implants are integrated into the lower jaw bone, “attachments” will be inserted into the bottom of the lower denture.  The attachments will allow the lower denture to “snap” onto the heads of the implants for stability and support.

In the next article (part 2), I will examine the different types of implant treatment modalities for full lower denture  stabilization.

Dr. Victor Sun Explains The Six Benefits of Dental Implants

Standard

stockphoto6

Having a great smile is one of the best attributes anyone can possess. Flashing those pearly whites is seen as an indication of a warm personality and can instantly attract others. A beautiful smile builds confidence and is a key factor in retaining good health in other areas of the body.

As we age, tooth deterioration often becomes a major factor in the search options for restorative treatment. If this is the case for you, you’re not alone. Many adults have lost some or all of their teeth to a variety of causes, including tooth decay, gum disease or accidents. Dental implants are the trusted way to experience life with intact teeth again.  You’ll find that the office of Dr. Victor Sun can help you on the journey to recoup the beautiful smile that’s so much a part of who you are.

What Are Dental Implants?

Dental implants are small artificial tooth roots, made out of titanium metal, placed under the gum into the jawbone. Just like real teeth! Implants are not the only way to replace missing teeth; bridges and dentures are other alternatives.  Dr. Sun can create the best treatment plan based on your individual needs.

What Are The Six Benefits Of Dental Implants?

1) Durability:  Dental implants, if cared for properly, can often last a lifetime. Of course, good oral hygiene and regular dental visits are important.

2) Appearance:  The only person who will know about your decision to have dental implants is you. Implants are made to look and feel just like your natural teeth. As a result, your self-image will remain positive since dental implants are virtually undetectable.

3) Convenience:  There is no fuss over removable dentures. With dental implants, you don’t have to worry that they might slip out of position because the framework is permanent. In addition, you won’t have to deal with any messy glue that helps hold removable dentures in place.

4) Improved Speech:  If you wear dentures, you no longer need to worry about slipping teeth that might cause you to slur your words.

5) Improved Self-Image:  Dental implants help restore your youthful appearance and help you feel better about yourself.

6) Improved Oral Health:  Unlike tooth-supported bridges, dental implants don’t involve any anchoring to your surrounding teeth. Keeping the other teeth intact makes cleaning easier, which enhances your oral health.
