What is bone grafting?
Ideally, a dental implant will be placed by drilling a hole to a toothless site. Fortunately, with the advancement in Dentistry, a dental implant can be placed directly at the extraction site or at the hole left by the tooth which is called Immediate Dental Implantation.
Immediate Action pays off
Whether a single tooth is removed or multiple teeth, it has negative effects not just on the appearance but also with function.
Bone loss occurs after tooth removal which affects bone height and width of the jaw. As the bone collapses, lips and cheeks will lose support which makes a person appear older. Bone continues to recede over time with the absence of stimulation made by the tooth root.
Moreover, bone loss can cause functional problems in the mouth. The tooth adjacent to the removed tooth may tilt. A tilted tooth will make it difficult for a future restoration (i.e. implant or bridge) to be seated due to loss of space. The opposite tooth (above or below the tooth removed) can move out of its socket, or supraerupt, due to loss of contact or interaction with another tooth. Both tilted tooth and supraerupted tooth causes biting or chewing problems and can eventually cause joint problems (TMJ Disorder).
The dentist will diagnose if you are a good candidate for immediate dental implantation by taking series of radiographs. To undergo immediate dental implantation, you should be free of any gum disease and has a healthy bone with no bone loss recorded.
It is contraindicated for a tooth with pus, bone loss, or is close to a vital anatomical structure like a nerve.
The dentist will diagnose whether an infected tooth is still restorable or not. An infected tooth is usually indicated for tooth removal once it cannot be restored with a tooth filling, root canal treatment or dental crowns. Extraction is followed by placement of dental implants immediately.
Extraction & First Phase of Immediate Dental Implantation
- Local anaesthesia will be administered to numb the tooth and gums.
- The dentist/surgeon will use hand instruments to remove the attachment of the tooth from the bone for easy removal.
- Using dental forceps, the tooth will be removed out the socket.
- The hole or socket will be carefully inspected. Irrigation using saline will be used to remove any debris.
- An osteotome, surgical-bone cutting instrument, will be used to prepare a socket to the desired depth.
- When desired depth is attained, the dental implant is placed.
- A radiograph is taken to verify the position of a dental implant.
- A temporary restoration (i.e. denture) will be made for patient’s use until next appointment.
Second Phase of Immediate Dental Implantation
- After three to six months, the dental implant will be fully integrated to the bone. Once osseointegration transpired, the second phase of the implant will be facilitated.
- During the second phase, another part –final abutment– of the implant will be attached. Then, a mould of the upper and lower jaw will be taken for fabrication of the final prosthesis (tooth crown to be attached to the implant) and will be sent to the dental laboratory.
- Once the final prosthesis is delivered back to the clinic, you will have your next appointment for tooth crown’s attachment to implant.
