Bone Resportion
Bone resorption is a common complication of
tooth removal—one which makes it challenging to replace the teeth esthetically.
Fortunately, dentistry has been at the forefront of development in bone
science, and offers several common techniques to avoid bone resorption and
reconstruct resorption defects. This animation illustrates removal of a lower
molar tooth, and the subsequent bone resorption which takes place. Pressure
resorption of an edentulous area is shown under a removable partial denture.
Compromised placement of a dental implant into an atrophic area of the mandible
is animated, and compared with a fixed bridge as a restorative option. Bone
resorption in the esthetic zone is then illustrated, showing the cosmetic
compromises which must be made if bone grafting is not undertaken prior to
restoring the edentulous area. Compromises in implant placement are shown.
Sinus pneumatization is animated, and sinus elevation is briefly mentioned as
an option. A block cortical graft is quickly shown, followed by placement of a
dental implant and restoration with a crown. The animation closes by showing a
socket graft to preserve alveolar bone following an extraction.
