What are Intrabony defects?
The intrabony defect is a specific osseous defect with definite morphology; it is not just any defect with the base of a perio- dontal pocket apical to the alveolar crest. The intrabony defect is surrounded by bony walls on three sides with the tooth root forming the fourth wall.
What is combined osseous defect?
Combined: the no of walls in the apical portion of the defect may be greater than that in its occlusal portion. Osseous craters are concavities in the crest of the interdental bone confined within the facial and lingual walls.
What are bony defects?
A bone defect is a lack of bone where it should normally occur. Bone defects may be caused by trauma, tumor, or infection (osteomyelitis). Surgical reconstruction of bone defects can present significant challenge for the orthopedic surgeon.
What is Suprabony defect?
Suprabony means above the bone crest. When periodontal infection results in the development of an intrabony defect, the base of the pocket is apical to (or below) a wall of bone. By contrast, when a suprabony pocket develops, the base of the defect is coronal to the crest above the bone.
What is the difference between horizontal and vertical bone loss?
If both the surfaces had horizontal type of bone loss, then the tooth was assigned to have horizontal bone loss. If one of the tooth surfaces had a vertical defect or both the surfaces had vertical defects, then the tooth was assigned to have vertical bone loss.
What is a Hemiseptal defect?
Hemiseptal defects i.e., vertical defects in the presence of adjacent roots and where half of a septum remains on the tooth, represents a special case of one-wall defects and the treatment is always a challenge despite the various periodontal regenerative therapies.
What is a Suprabony defect?
How are bone defects treated?
Smaller size defects can be treated with simple bone fixation and some debridement. Larger bone defects must be treated with bone transport (Ilizarov method) or transplant of bone graft with vascular pedicle [36].
What are the different types of infrabony defects?
Infrabony Defects. 1. Infrabony defects when bone resorption occurs unevenly, an oblique direction. In infrabony defects of bone resorption primarily affects one tooth. 2. Classification Infrabony defects. Infrabony defects are classified based on the number of bone wall.
Where can I find information on intrabony defects?
1 Department of Periodontics, School of Dentistry, University of Maryland, Baltimore, MD. Background: Treatment of intrabony defects is an important therapeutic goal of periodontal therapy.
Is it possible to regenerate an intrabony defect?
Conclusions: Periodontal regeneration of intrabony defects is possible using a variety of regenerative strategies. long-term success. Clin Adv Periodontics 2015;5:21-29. Key Words: Bone transplantation; guided tissue regeneration; periodontitis; regeneration; surgery, oral. . and intrabony defects. Conventional surgical approaches, epithelium.
How are intrabony defects used to treat periodontitis?
Summary: The predictable regeneration of intrabony defects remains an important goal in the management of periodontitis. Clinical and histologic evidence of periodontal regeneration has been shown for multiple regenerative therapies, including bone replacement grafts, guided tissue regeneration, and biologics, when used alone or in combination.
