Dr. Luc Vrielinck, Genk/Belgium, provides an overview of zygomatic implants. Various indications for the use of implants are presented together with a discussion of the preoperative diagnosis and planning required. The planned prosthesis determines the number and position of the zygomatic implants to be inserted. However, a distinction must be made in this respect between fixed and removable prostheses in particular. Prior to the surgical procedure, medical imaging is always recommended together with subsequent evaluation of the existing bone structure as well as simulation of the planned implants on a computer.
Dr. Vrielinck describes his approach to inserting zygomatic implants and presents the instruments required to perform the surgical procedure. The presentation concludes with the individual steps involved, as well as the considerations that must be taken into account in prosthetic restoration. In this respect, it is particularly important that the prosthesis fits correctly and that the load is evenly distributed across the individual implants if implant durability is to be ensured. Case studies are used to illustrate successful prosthetic rehabilitation using zygomatic implants that offers long-term stability. The removal of zygomatic implants that are not worth retaining is also discussed, although this rarely occurs.
