The role of implants in restorative dentistry: prosthesis design and aesthetic considerations

When implants are used to anchor an intra-oral prosthesis, the resulting dentition should not only function well but also be aesthetically pleasing. Both aspects must therefore be carefully considered in the assessment of each case. Optimal aesthetics can be achieved only if a number of criteria, of which the amount and quality of bone present in a potential implant site are most important, are fulfilled. Collapse of the labial cortical plate is common, occurring two to three years after extraction. It can result in palatal placement of implant fixtures, leading to a poor crown emergence profile. Insertion of an implant fixture after initial socket healing but before resorption has occurred will maintain the labial contour. This technique is being used with increasing success.
