Determining replacement teeth position for the implant-retained prosthesis in the edentulous patient

A pleasing final appearance is vitally important for patients who undergo extensive oral rehabilitation. This applies equally to the fields of orthodontics, restorative, prosthetic, and implant dentistry. In the field of removable prostheses there are biometric guides that aid in the replacement of teeth especially when the anatomical ridges are severely resorbed. These guides should be considered when planning the appearance and function of prostheses. This paper suggests that in view of the fact that unfavourable placement of implant fixtures is not easily rectified, knowledge of biometric guides can be critical in the treatment planning of the implant supported prosthesis especially when there are large resorbed edentulous spans.
