Under the circumstances of missing tooth, conventional fixed partial denture was utilized to restore the missing span with consideration of function and esthetic. In order to create ideal pontic form, restoration was performed frequently after complete healing of ridge. After removal of the tooth with modeling and remodeling process, changes in socket healing and volume of alveolar ridge occurred. Initial ridge resorption can occur up to 25% to 30% within three to six month and up to 50% in one year. After one year of alveolar ridge resorption, the resorption rate slows down but continues to the basal bone level. When fixed partial denture was delivered simultaneously with tooth extraction, few advantages and disadvantages were observed. The disadvantages involved creation of ideal pontic form and good diagnosis of periodontal evaluation. The advantages involved shortening of treatment time and maintenance of soft tissue profile with preservation of the alveolar ridge at longer periods.
