I treatment planned a patient for an implant supported fixed detachable prosthesis [hybrid] in the maxilla. I originally planned for 5-6 implants spaced around the arch. During implant installation, I was only able to place 4 BioHorizon 3.4/9 implants in the #5, 9, 11 and 12 sites sites because of bone deficiency in th maxillary right anterior. Will these 4 implants be able to support a hybrid? I would also like to cantilever the first molars and second premolars. Or should I do bone augmentation in the maxillary anterior and place additional implants?
