ABSTRACT
INTRODUCTION Planning for implant-supported fixed bridges follows the lines described in the previous chapters. The chapter on single tooth replacement in the anterior region dealt with the aesthetic demands and the chapter on molar replacements with some of the loading and spacing considerations. Small edentulous spans with adequate bone volume can be relatively straightforward (Fig. 5.1A,B). Extensive bridgework in partially dentate and edentulous jaws involves planning for placement of multiple implants in sites that may be more demanding surgically (see chaps. 10 and 12). The number and distribution of implants in such cases is a complex variable and is discussed below.
