Types of procedures in dental bone grafting - Health - Dental Care

Its very important to have adequate jawbone on which the dental implant or mini dental implant have to rest. Sometimes the missing bone needs to be replaced or some amount of mass is needed to be added to make the procedure of fixing dental implants successful. This additional bone mass is obtained in various ways. The sort of methods are illustrated below:

Xenografts: In this method the bone is obtained from body of dead animal mostly cow. Its not directly used in human body, before using the bone is sterilized and then fixed in body. The plus point is that the surgery is sinlge step process . Inspite of this, this method is not so widely put to use because many people are reluctant to accept an animal's body part in their body.

Allografts : In this case, bone mass is taken from a dead human's body in the same fashion as eyes and other organs are donated. These bones are also sterilized before use. A disadvantage with this is that there is danger of diseases being transferred and again people refrain from this since accepting a bone mass from another human their mouth is not easy for them.

Alloplastic grafts : This is the procedure wherein, an artificial bone made of calcium phosphate is fixed in the patient's mouth in the required site. It is easily accepted by body as the material is biodegradable. This has the advantage of getting exactly the right amount of bone material needed with no chances of transfer of diseases and takes only one surgery.

Autografts : This procedure will allow the bone to be taken from person's other body parts. As teh bone is taken from only from patient's body part only tehn chances of rejection by oral tissues is negligible. There is no possibility of the person getting any transferred disease since the bone belongs to the same body. Though this procedure can be painful as two surgeries are done.

Growth factor enhanced grafts : This is more expensive since this involve recombinant DNA technology. In this human growth factors are present like bone morphogenic proteins with a material like collagen as the carrier medium. They are beneficial in speeding up the process of bone formation.Tissues of bone grow faster than tissues of gum. Hence there is risk of the grafted bone getting covered by the gum tissues after a period of time. To avoid this situation, dentist will fix the membrane over bone to fix the dental implant properly for lasting long..
