Periodontal Regenerative Therapy

To be successful a bone graft needs to regenerate not only the cortical bone that supports a tooth but also a material called cementum to which it will attach. The connection between these two materials is called the periodontal ligament and in the healed bone graft it too will be regenerated.

When bone is lost due to periodontal disease the gums often recede exposing the roots of the teeth. This condition common to periodontal disease, requires another kind of regenerative procedure the periodontal (gum) graft. Full periodontal regenerative therapy involves treatment planning for the various different grafting procedures needed in an individual case.

It is always the goal of periodontal therapy to try to retain the patient's own teeth and gum tissue. However, with advanced disease or trauma sometimes this is not possible. Periodontal regenerative procedures are also utilized to enhance the quality and quantity of bone in preparation for implant therapy or bridgework.

Periodontists have a number of options when a patient's condition requires a bone graft to rebuild lost bone. The grafting material can be taken from the patient's own bone tissue. More commonly periodontists will utilize bone products from tissue banks or purely synthetic materials.

Recent scientific advances have allowed the use of highly sophisticated tissue engineered products. The professionals at Century City Periodontics are highly trained in the use of currently available grafting techniques and the use of all the available grafting materials.



 
Sometimes the gums look like they are normal and there are no problems.   Performing pocket depth measurements may reveal severe pocket depths as well as bone defects.

 
The outline of the flap is seen on this slide.   The gingival flap is retracted to expose the defect.

 
A bone substitute allograft or autograft, is placed to fill the defect. The area is filled as desired.   The bone will be filled with blood and a clot will form. note other bone growth activating agents may be mixed in with the bone substitute.

   
It is recommended that a membrane is used to cover the area and prevent the soft tissues (gums) from growing into the space.    



 
This membrane keeps the shape of the new bone as well.   The flap is placed back and sutured.

 
The membrane resorbs with time. Depending on the type used this should totally resorb within 6-10 weeks. The bone will then mature to alveolar bone.   With successful bone regeneration normal pocketing will be restored.
