Dentists and patients become increasingly aware of the complex and predictible results offered by implant-supported dentures. These alternatives fulfill the demands of modern dentistry to rehabilitate the oral health condition according to the highest standards. A deficient residual crest represents a great challenge for the healing and osseointegration of the implants. Dental implants have an essential effect on stopping bone atrophy in the edentulous crest and preserving its condition. Function and esthetics and the patients comfort can be rehabilitated within normal limits. The prosthetic reconstruction based on osseointegration implants has better long-term prognosis if the therapeutic option is judiciously selected. The risk of relative movements at the bone-implant interface decreases according to the difference in value between the elasticity module of the implant and the bone. Prosthetic reconstruction based on implants has a better long-term prognosis if the therapeutic option is judiciously selected from all possibilities according to the osteointegration of an adequate number of implants.
