BONE GRAFTING
SOLUTION FOR NOT ENOUGH BONE FOR DENTAL IMPLANTS
Bone graft (aka. GBR) is a procedure required when there is insufficient bone volume to receive a dental implant. The bone acts as the foundation that the implant requires to for long term success and stability, so bone grafting can be used to rebuild lost bone to support implants.
Bone Grafting (aka. Guided Bone Regeneration) is a procedure that allows to regenerate and grow bone that has been lost due:
-
teeth extractions
-
missing teeth
-
periodontal bone diseases (periodontitis)
-
facial trauma
BONE GRAFTING & RIDGE AUGMENTATION
Dental Implants cannot be placed in the upper or lower jaw bone if it is not sufficient in size due to bone loss (aka. jaw bone atrophy).
Single Tooth
Upper Jaw
Lower Jaw
CAUSES FOR LOSS OF TEETH
Large Cavity - Failed Root Canal - Tooth Fracture from Clenching & Grinding - Periodontitis - Gum Abscess Infection - Tooth Knocked out from Facial Trauma - (Fight, MVA, Sports - Boxing, Hockey, Soccer)
LOSS OF TEETH LEADS TO JAW BONE LOSS
1. Upper Jaw Bone Loss (atrophy) after tooth removal
2. Facial Changes from Upper Jaw Bone & Lower Jaw Bone Loss (atrophy)
3. Lower Jaw Bone Loss (atrophy) after tooth removal
BONE GRAFTING & RIDGE AUGMENTATION REGENERATES & GROWS BONE BACK FOR IMPLANTS
Bone Grafting & Ridge Augmentation procedures are used to grow and regenerate bone that has been lost (aka. Jaw bone atrophy).
Jaw bone loss jaw occurs when a tooth or multiple teeth are lost from:
-
dental extraction due to large a large tooth cavity, failed root canal tooth, or tooth fracture from clenching or grinding
-
periodontal gum and bone disease (aka. periodontitis)
-
dental emergency trauma injury due to a tooth being knocked out from a fight, fall, playing sports or other facial trauma
WHEN HAPPENS IF YOU DON'T BONE GRAFT AFTER A TOOTH LOSS?
Bone loss after a tooth has been extracted will occur and the jaw bone will shrink in width and height if a bone graft is not done simultaneously.
Premature aging is caused by tooth loss and bone atrophy. Also, the loss of bone volume will make placing an implant more difficult in the future and change your facial esthetics.
Bone Grafting and socket preservation procedures allows for the bone to heal with adequate volume (width and height) so a sufficient bone volume is present to receive a dental implant.
The bone acts as the foundation that the implant requires to for long term success and stability, so bone grafting can be used to rebuild lost bone to support implants.
BONE GRAFTING TECHNIQUES
Bone graft is a surgical procedure that replaces missing bone for dental implant and there are various techniques to regenerate the missing bone. Tooth loss will result in changes to the surrounding bone and gums.
1. SOCKET GRAFT PRESERVATION
Once the tooth has been extracted, the empty socket is filled with bone grafting material. After the bone graft has been placed it will be covered up with an artificial membrane to help stimulate the bone regeneration in the empty socket and prevent the gum tissue from growing into the bone. The gum is used to cover up the artificial membrane to protect it. Socket Preservation is very successful in helping minimize bone and gum shrinkage and collapse. The newly formed boned in the tooth socket that was extracted provides a stable and strong foundation for a dental implant.
2. PARTICULATE GRAFT - RIDGE AUGMENTATION
Particulate bone graft procedure can be used when the teeth are extracted or if teeth have been missing for a while and there is moderate bone loss that will not allow a dental implant to be placed.
The particulate bone graft procedure can be completed by placing a softer mix of bone substitutes where the bone is missing and covered with a tarp called a membrane. This graft allows bone to grow and regenerate to allow dental implants to be placed in a stable foundation.
3. BLOCK GRAFT - RIDGE AUGMENTATION
Block bone grafting procedure can be used when extensive bone is loss is present by placing blocks of bone in the area of missing bone and held in place with titanium screws during the healing phase for 4-6 months.
The newly formed bone provides a stable foundation for dental implants.
DIFFERENT TYPES OF BONE GRAFT MATERIAL
There are four main types of bone grafts that will be chosen based on grafting situation:
-
Autograft – bone used from the patient’s own body.
-
Allograft – bone from a genetically similar organism
-
Xenograft – bone from a genetically dissimilar organism
-
Synthetic – a synthetic biocompatible material
-
-
The type of bone graft that will be chosen will depend on the situation, and the amount of bone required.
