Rehabilitation of Atrophic Maxilla using Pterygoid Implants: Case Reports by Jimoh Olubanwo Agbaje, Jan Meeus, Luc Vrielinck and Henri Diederich in Modern Approaches in Dentistry and Oral Health Care in Lupine Publishers
Abstract
Restoration of a severely atrophic jaw presents a challenge in
dentistry. Bone augmentation is usually required in the posterior
maxilla to enable placement of a sufficient number and length of
implants to support implant prosthesis due to the poor bone quality of
the posterior maxilla. The recent invention of new surgical techniques
and implant systems help circumvent the current restorative problems and
provide a solution to erstwhile un-rehabilitated cases. The use of
pterygoid implants in the pterygo-maxillary region provides posterior
bone support without sinus augmentation or supplemental grafts. This
article describes a clinical procedure for the restoration of severely
resorbed maxilla using a new pterygoid implant in combination with
conventional or cortically fixed implant system. In the present study,
the use of implants in the posterior maxilla to support a fixed
prosthesis was demonstrated to be a reliable and a good alternative to
distal cantilever prostheses or sinus-lifting procedures.
