Principles of the design and fabrication of implant-supported maxillary prostheses are described. The significance of the maxillomandibular relationships, maxillary arch size to the location of the implants, and the positioning of the restored dental arch are discussed. Angulated abutments may overcome conflicts between the position of the artificial teeth and the implants. Solutions to design features that may impair achievement of a pleasing appearance, good gingival health, and well-articulated speech are considered.
