Dental Implant Dentistry

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.
