EXAM 2 Principles of Osseous Resective Surgery Flashcards
what is described by the following definition:
bony deformities are not uniform: often a combination of horizontal and vertical loss
concavity or deformity in alveolar bone involving one or more teeth
osseous defect
T or F
the presence of osseous defect is a sign of active disease
false
it is not a sign of active disease
an osseous defect is an osseous deformity resulting from ___
periodontal disease
what two things can be used in the diagnosis and evaluation of an osseous defect?
radiographs and probing
radiographs can reveal the existence of ___ in the interproximal space, but only provides ___ information
- angular bone loss
- 2-dimensional
probing supplies only ___ measurements of the soft tissue pocket
linear
what is transgingival probing?
- “bone sounding”
- indicates the topography of the bony defect in two directions
- vertical and horizontal
what are the three classifications of osseous defects?
- 3-wall infrabony defects
- 2-wall infrabony defects
- 1-wall infrabony defects
___-wall infrabony defects are usually located in the interdental region
3-wall
3-wall defects consist of which 3 walls?
facial, proximal, and lingual
what is the name for 3-wall defects that wrap around the tooth involving two or more contiguous root surfaces?
circumferential defects (a type of 3-wall infrabony defect)
what are the 4 additional designations for 3-wall infrabony defects?
narrow, wide-mouth, shallow, and deep
what is another word for infrabony?
intrabony
what are the two types of two-wall infrabony defects?
interdental craters and two-wall hemiseptum
what are the most common bony defects?
interdental craters (2-wall)
interdental craters are located ___
interdentally
interdental craters consist of what 3 things?
facial bony wall, lingual bony wall, two adjacent roots
what infrabony defect is described as 1/2 of an interdental septum, and a lingual and proximal wall or a facial and proximal wall?
2-wall hemiseptum (2-wall infrabony defect)
what infrabony defect is described by the following:
remaining one wall usually located interdentally (hemiseptum); may also be located on facial or lingual aspect
1-wall infrabony defect
what is described by the following:
the general term for procedures which modify and shape bone defects and deformities
may be defined as a procedure which aims to eliminate deformities induced by periodontal disease process or other related factors, such as exostosis and tooth supraeruption
osseous surgery
what are the 2 types of osseous surgery
- additive osseous surgery (regenerative)
- subtractive osseous surgery (resective)
what are the 5 therapeutic choices for osseous defects
- osseous recontouring (osteoplasty vs. ostectomy)
- induce regeneration of bone
- root resection with osseous resection
- maintenance of the pockets associated with osseous defects
- tooth extraction
