We studied how one stage prosthetic treatment (immediate and early placement of prostheses) and two stage (delayed placement of prostheses) affected implants. We used the two dimensional finite element method (FEM) of analysis to investigate the effect of several different prostheses on the stress distribution in implants, teeth and the supporting bone. We also analyzed data from an electronic dynamometer apparatus to clinically measure the forces on the dental implants during the healing phase. The FEM indicated that there were low compressive stresses with bridges made of acrylic materials. These stresses were even lower when we used a new design removable fixed prosthesis. Results obtained using the electronic ignatodynamometer apparatus indicated that the masticatory forces on the implants during healing were different for the maxilla and mandible, and for males and females. In addition, the forces gradually increased during healing, which continued for three to six months. We concluded that immediate and early loading of dental implants was possible and beneficial when a special removable fixed temporary prosthesis was placed during the healing period. This technique significantly shortens the treatment period. (J Osaka Dent Univ2003; 37: 129-133.)
