Abstract
Implant-supported prosthetic rehabilitation represents one of the most common procedures in dental clinical practice.1 The recent development of computer- aided design/computer-assisted manufacture technology for surgical planning and fabrication of custom surgical templates has led to minimally invasive, valid, and simplified surgical approaches.2,3 Preoperative computer-guided three-dimensional planning of implant treatment takes into account bone quality and quantity and can therefore avoid bone augmentation procedures in many patients with atrophied jawbone. 2,4 However, accurate implant planning and strict adherence to standardized surgical protocols is mandatory to minimize the risk of complications during the surgical phase.4 Intraoperative implant displacement into the paranasal sinuses has been reported frequently. 5–10 Any surgical treatment that includes the posterior maxillary region, whether for dental placement or extraction of third molars, has to take into account the maxillary sinus because of its anatomical position.11 Infratemporal fossa involvement is less common after implant surgery or exodontia, and it is usually associated with an inaccurate preoperative evaluation or an incorrect inclination of the pterygoid implant during its insertion.12,13 To the authors’ knowledge, this is the first report of dental implant dislocation during computer- assisted implant positioning.
