“…The American College of Prosthodontists position statement on pterygoid implants states: “implants in the pterygoid region offer a scientifically validated and predictable treatment option.” Surgical complications related to implants in the pterygomaxillary region have been limited to slight venous intraoperative bleeding that subsided with implant placement and to trismus . This article is the first to report a major complication related to implant surgery in the pterygomaxillary region and the importance of an appropriate referral to our medical colleagues for implant removal.…”

The placement of dental implants in the pterygomaxillary region can be advantageous in maxillary complete arch fixed implant-supported prosthetic rehabilitations to avoid bone grafting and sinus elevation surgeries. Pterygomaxillary implants improve implant biomechanics by eliminating distal cantilevers and increasing the anteroposterior spread with reported mean implant survival rates comparable to traditional implant sites. Although only minor surgical complications have been reported in the literature with the placement of dental implants in the pterygomaxillary region this clinical report describes a major surgical complication involving the displacement of a dental implant into the pterygoid fossa.

“…Notwithstanding the use of pterygoid implant is a reasonable option, this technique has not been widely used because of the difficulty of surgical access in this area (insertion of a long implant with a semi-blinded surgery made free-hand), the presence of vital structures (greater palatine artery and pterygomaxillary fossa), and the prosthetic difficulty in the short-(tilted implants in a limited vertical space of this region) and long-term (owing to high occlusal masticatory stresses in this area that could end in prosthesis or screw fractures) [24][25][26][27][28][29][30].…”

“…For the above mentioned reasons, the accurate placement of pterygoid implants (13-20 mm of implant length) using free-hand techniques becomes incredibly difficult compared with the other proposed techniques for the rehabilitations of atrophic edentulous maxilla [26][27][28][29][30].…”

Accuracy Evaluation of 14 Maxillary Full Arch Implant Treatments Performed with Da Vinci Bridge: A Case Series

The use of pterygoid implants can be an attractive alternative to sinus bone grafting in the treatment of posterior atrophic maxilla. This technique has not been widely used because of the difficulty of the surgical access, the presence of vital structures, and the prosthetic challenges. The use of dynamic computer aided implantology (DCAI) allows the clinician to utilize navigation dental implant surgery, which allows the surgeon to follow the osteotomy site and implant positioning in real time. A total of 14 patients (28 pterygoid implants and 56 intersinusal implants) were enrolled in the study for a full arch implant prosthetic rehabilitation (4 frontal implants and 2 pterygoids implants), using a dynamic navigation system. The reported accuracy of pterygoid implants inserted using DCAI was 0.72 mm at coronal point, 1.25 mm at apical 3D, 0.66 mm at apical depth, and 2.86° as angular deviation. The use of pterygoid implants in lieu of bone grafting represents a valid treatment opportunity to carry out a safe, accurate, and minimally invasive surgery, while reducing treatment time and avoiding cantilevers for a full implant prosthetic rehabilitation of the upper arch.
