title: Maxillary all-on-four therapy using angled implants: a 16-month clinical study of 1110 implants in 276 jaws.
abstract: The maxilla is a challenging area for dental implant restoration. Encroachment of anatomic structures such as the sinus and nasal floor make vertical placement difficult. Implants placed at an angle may be used to avoid these anatomic structures or eliminate the need for a bone grafting procedure. The question occasionally arises about the possible detrimental effects of placing implants at an angle. This article reviews relevant literature, presents two case reports on maxillary angled implants and presents 3 years of data on 276 All-on-Four restorations.
