Abstract:

Dental implant restoration is an effective way to restore the chewing and aesthetic function for edentulous. However, dental implant restoration is facing great challenges of the lack of available bone, the maxillary sinus or inferior alveolar nerve vascular bundle, which is often necessary to carry out the related bone augmentation operation. All-on-Four technique is to use four implants in the anterior part of complete edentulous jaws, the two most anterior implants are placed axially whereas the two posterior implants are placed distally angled, to support a provisional, fixed, and immediately loaded prosthesis. The technique avoids the artificial bone substitutes implantation and maxillary sinus augmentation or other bone augmentation surgery. Besides, it could alleviate patients' psychological reaction, postoperative reaction, as well as time and money costs. It is considered a feasible treatment method to combine the application of the oblique implant and the axial implant in the treatment of the edentulous patients. This paper will elaborate on the concept of All-on-Four, the conventional technology, the evaluation research and some new viewpoints.
