In the edentulous upper jaw the placement of implants can be challenging due to limited bone quantity and the presence of the maxillary sinus. Pterygoid implants present an alternative option to use residual bone for implant anchorage and to overcome the need for...

Indications

Zygomatic implants have been documented as a an alternative for the rehabilitation of the atrophic posterior maxilla with both the classical two stage and immediate loading protocols. Zygomatic implants avoid grafting and sinus lift procedures and therefore contribut

Less than 4-6 mm of vertical residual bone height in the posterior segment of the maxilla is an indication for a sinus augmentation procedure [Esposito]. The external access to the maxillary sinus is carried out at a lateral buccal alveolar...

With appropriate pre-drilling based on their shape upon insertion into the bone, tapered implants will achieve a gradually increasing contact pressure with the surrounding bone and thus provide a high primary stability. This primary...

The treatment of the edentulous jaw can be a mixture of placing implants in healed and fresh extraction sockets. Unequal hard and soft tissue levels around the implants (Fig. 1&2), especially in the interforaminal region, can be adjusted by leveling the bone...
