Study Notes
Buttressing Bone Formation
- Development of thickened buccal alveolar bone occurs due to heavy occlusal forces.
- Buccal alveolar bone enlargements found in 25% of all teeth examined.
- Marginal bony lippings account for 18% of cases, while 7% demonstrate buccal exostoses.
- Initially proposed by Glickman and Smulow in 1965 as a response to occlusal trauma.
- Central buttressing bone forms within the jaw, peripheral buttressing occurs on the external surface, leading to bulging bone contours known as “Lipping”.
Bulbous Bone Contour
- Ledges represent plateau-like bone margins resulting from resorption of thickened bony plates.
Exostoses
- Exostoses are bone outgrowths of various sizes and shapes.
- Palatal exostoses prevalence is found in 40% of human skulls.
- Buccal exostoses seen in 25% of all teeth and 77% of individuals.
- Removal typically performed using a mono-bevel chisel and smoothing with a bone bur.
Fenestrations and Dehiscences
- Fenestrations are isolated areas where roots are denuded of bone but covered by periosteum and gingiva.
- Dehiscence extends the denuded area through the marginal bone, considered a more serious defect.
- Occur more frequently on facial bone than lingual surfaces, especially common in anterior teeth and often bilateral.
- Important for periodontal surgery outcomes, occurring approximately in 20% of teeth.
- Predisposing factors include prominent root contours, malpositions, and thin bony plates.
Reversed Architecture
- Loss of interdental bone alters normal architecture without loss of radicular bone.
- More prevalent in maxillae rather than mandibles.
Bone Deformities Classifications
- Classifications identified by Goldman & Cohen (1958), Glickman (1964), Karn et al (1983), Prichards (1985), and others including the Panos & Toneiti (2000) classification.
Osseous Craters
- Concave defects confined to the facial and lingual walls in interdental bones, constituting about one-third of all defects and two-thirds of mandibular defects.
- Occurrence is more common in posterior segments than in anterior segments.
- Ochsenbein's crater classification designates shallow (1-2 mm), medium (3-4 mm), and deep (5 mm or more) types.
Exostoses Etiology and Histology
- Etiology remains undetermined; potential causes include genetic, environmental factors, and masticatory hyperfunction.
- Histologically, exostoses display mature hyperplastic bone with cortical and trabecular characteristics.
- Usually are painless, self-limiting, and can contribute to periodontal conditions.
Tori
- Palatal tori mostly under 2 cm and prevalence ranges from 9% to 60%, more common than mandibular tori (5% to 40%).
- Prevalence rate for tori is 27 per 1,000 adults, with higher occurrence in females.
Surgical Techniques
- Removal procedures include an incision along the midline of the palate and mucoperiosteal flaps to access the exostosis.
- Treated by sectioning into smaller parts, using a fissure bur for effective excision.
