What is bone graft?

  • bone-graft-before
    Before bone graft, there was insufficient bone for implant placement.

Bone graft is a substitute bone which is used to restore and preserve jaw bone. Bone graft is primarily used for dental implant surgery and wisdom tooth socket preservation. Placing bone graft after tooth extraction assists your body in growing more of its own bone. Essentially, bone graft acts as a space maintainer by filling in the tooth extraction site. This allows your body to regenerate new bone at a better rate and results in more bone regeneration. If you like to learn more about bone grafts or other bone augmentation procedure, give us a call.

What is the purpose of bone graft?

Bone graft assists your body in healing better after tooth extraction. It also helps preserve more of your jaw bone. When you lose a tooth, your jawbone continues to shrink at an accelerated rate. Placing bone graft after tooth extraction helps preserve more of your jaw bone. This is important if you’re planning on placing a dental implant within the region. In order for dental implants to be successful, they must be placed in solid bone structure. Often times, the ideal spot for placing your dental implant lacks sufficient bone to fully secure the implant post. In these situations, your dentist has to add bone graft to prepare your jaw bone for implant placement. Schedule your appointment with Oceansight Dental & Implants to learn more about different bone grafting procedures. You can reach us at (949) 481-2540 to schedule your consultation.

Where do bone grafts come from?

bone-graft-material
Bone graft can be synthetic, come from cadavers, animals or from your own body

There are many different sources for bone grafting material. Each type of bone graft has its own implications and uses. Here is a list of the some common types of bone grafting material used in implant dentistry:

Synthetic bone grafts

Synthetic bone grafts are the most commonly used type of grafting material. They are made from material resembling bone particles, such as calcium apatite or calcium phosphate. Their purpose is to fill in smaller voids and defects to allow for more bone growth into the region.

Allograft bone

Allograft is bone graft which comes from cadaver or animal donor sites. These include bovine bone (cows), xenograft bone (pig bone) and human cadaver bone. Allograft bone doesn’t get resorbed over time as quickly as synthetic bone does. This makes allograft bone better at preserving voids and a better option for repairing larger bony defects.

Autogenous bone graft

Autogenous bone graft is bone that comes from your own body. Your implant dentist or oral surgeon harvests bone from a donor site within your own body. The donor site is typically the mandible ramus or chin region. For the most complicated cases bone needs to be harvested from your rib cage. Autogenous bone graft is typically reserved for repairing the largest bony defects when there are no alternative options.

All bone grafts function similarly by helping your body regenerate more of its own bone. They essentially act as a space holder to permit your own bone to grow into the graft region. As you deposit more bone, your body gradually absorbs and replaces most of the bone graft material in your body. Once you develop enough solid bone, your dentist can now secure your dental implants in place and restore your missing teeth.

What is a sinus lift or graft?

Sinus-Lift-Graft
Sinus lifts restore sufficient bone below your sinuses to allow for implant placement

A sinus lift or graft is required when there is not enough bone to place dental implants in the upper posterior region. For those of you with a knowledge of teeth numbers, this includes teeth #2, 3, 4, 13, 14, 15 and less commonly teeth #5 and 12. The upper posterior jaws typically lack sufficient bone for implant placement. This is primarily due to the proximity of the maxillary sinuses. In order to restore enough bone, a sinus lift or sinus graft is performed. Here is a bit more information about these sinus different surgeries:

Sinus lift surgery

sinus-lift-dental-surgery
During a sinus lift, your dentist will push your sinus membrane up by a few millimeters

You require a sinus lift whenever there is about 5 to 8 millimeters of bone under your sinus membranes. During sinus lift, your dentist will gently push and lift your sinus membrane upwards. This creates additional room to add bone graft and place a large enough dental implant to support your bite.

Lateral wall sinus graft

lateral-wall-sinus-graft-dental-surgery

A lateral wall sinus graft is required whenever there is less than 5 millimeter of bone under your sinuses

A lateral wall sinus graft is required whenever there is very little bone under your sinus membranes. Typically, whenever there is less than 5 millimeter of bone under the sinuses you require a lateral wall graft. A sinus lift alone can not restore sufficient bone for implant placement under these circumstances. This is an extensive surgery that requires adequate preparation and diligent follow-up.

To perform a lateral wall sinus graft your dentist will create an opening in your upper jaw using a lateral wall approach. Next, your dentist will separate and gradually lift your sinus membrane. Finally, your dentist will add a significant amount of bone graft material to prepare the area for implant placement. We perform all types of sinus lift and grafting procedures at Oceansight Dental & Implants. To learn more, schedule your appointment by calling (949) 481-2540. We offer bone grafting and dental implant treatment to San Clemente and the rest of Orange County.

When do you need bone graft or sinus lift surgery?

Bone graft is required whenever there is not enough jaw bone to place dental implants. Your dentist will start by examining your jaw bone using X-rays and CT scans. If you have sufficient jaw bone, then your dentist can proceed with dental implant surgery. However, if you don’t have enough bone structure then a grafting procedure is necessary. The type of grafting procedure depends on the where the implant(s) is being placed and how much original bone structure you currently have. Schedule your consultation with Dr. Jazayeri today to see if you are a good candidate for bone grafting and dental implant treatment.

Definition of Dental Implant Terminology

Abutment

An abutment is a dental implant component which connects the implant post to the implant crown. Abutments are typically made from metal, although full ceramic options are available as well.

All-on-four dental implants

A full set of prosthetic teeth which is completely supported by four or more dental implants. All-on-four teeth replace all of your missing teeth in each arch with fixed, permanent teeth made from porcelain or zirconia.

Bone Graft

Bone substance used to preserve and restore jaw bone during dental implant treatment. Bone graft comes in many varieties including synthetic bone cadaver bone, animal bone and your own bone.

Ceramic Implant Post

A dental implant post which is made from zirconia instead of traditional titanium alloy. Zirconia dental implant posts are a good option for those allergic to metals or suffering from autoimmune conditions where they don’t react well to titanium.

Crown (Implant crown)

A crown is an artificial tooth, consisting of porcelain or ceramic, which covers the implant to resemble a tooth. Crowns function and look like your natural teeth.

CT Scan (or CBCT scan)

A 3-D image of your jaw structure used in implant dentistry. CT scans capture vital structures and your bone thickness to better assist your dentist in correctly positioning your implant posts.

Dental Implant

An artificial tooth which fully replaces your missing tooth. Dental implants typically consist of three parts: Implant post, abutment and crown.

Denture

Removable teeth which replace your missing teeth and supporting gum tissue. There are many different types of dentures based on how many teeth you are missing and where these teeth are located.

Full mouth dental implants

A complex process to replace all of your teeth with dental implants. Full mouth dental implants requires building up your bone and replacing your teeth with 8 to 12 dental implants. The end results is fixed, permanent crowns and bridges fully supported by dental implants.

Healing Cap (Permucosal extension)

An implant part which temporarily attaches to your implant post. Healing caps are typically placed during second stage surgery. They remain in place for a few weeks and allow your gums to properly form around the implant in anticipation of your final crown.

Immediate load

A process by which an implant post receives a temporary crown or denture the same day as it is placed. Immediate load is only recommended for teeth-in-a-day or missing front teeth in those who qualify.

Immediate placement

A process by which your dentist removes your bad tooth and places the implant post in one day. Immediate load is recommended for teeth which don’t have extensive bone loss or infection.

Implant dentistry

A branch of dentistry which focuses on restoring your missing teeth with dental implants or implant supported prosthesis. Typically performed by experienced general dentists, periodontists and oral surgeons.

Implant post

A screw-like device which is placed in your jaw bone. Implant posts are usually made from titanium or zircoina. Implant posts are used to support crowns, bridges or dentures.

Osseointergation

A process by which the implant post fuses and locks into your jaw bone. Osseointegration usually takes between 3 to 9 months, depending on the quality of your jaw bone and overall health.

Overdentures

A set of dentures anchored in place via 2 to 4 implant posts or an implant bar. Overdentures are still removable dentures, however, they are more stable since they are supported by a few implant posts.

Second stage surgery

A minor procedure performed after your dental implants complete their osseointegration. Your dentist exposes the implant posts, placed healing caps on them and sutures your gums to allow them to heal properly.

Teeth-in-a-day

A process by which your bad teeth are removed and a set of teeth are inserted into your mouth all on the same day. Teeth-in-a-day is temporarily placed screwed in place while your dental implants continue to heal so that you are not walking around toothless during the recovery period.
