Dental Implant Migration into the Ethmoid Sinus

Migrated Maxillary Implant Removed via Semilunar Hiatus by Transnasal Endoscope

“…Migration of the dental implant into the paranasal sinuses or complicated maxillary sinusitis was some times reported 6 . Specific procedures have been indicated for the treatment of migrated implants, although the indications may vary depending on the symptoms in the maxillary sinus.…”

Implant Complications

“…In general, implant displacements occur sometimes after an implant placement because there is an absence or loss of osseointegration and, therefore, of stability (low osseous density around it). Nevertheless, some authors report the displacement of implants into the maxillary sinus during their installation (Chappuis et al, 2009;Felisati et al, 2007;Haben et al, 2003). When this happens, the implant remains, in almost all the cases, lodged inside the sinus (Chappuis et al, 2009;Borgonovo et al, 2010), and can be removed a few days later by opening the lateral wall of the maxillary sinus (Haben et al, 2003) (Fig.…”

In these intra-or postoperative cases, authors recommend the immediate removal of the implant lodged in the maxillary sinus (Ramotar et al, 2010;Galindo et al, 2005;Felisati et al, 2007;Haben et al, 2003) through an intraoral or trans-nasal via that will prevent further associated complications; although it is in general asymptomatic condition, most patients suffer from a marked sinusitis.…”

Surgical Alternative in Sinus Lift Reoperation

“…As a consequence, some professionals avoid reconstructive techniques using short and thin implants [9]. Nevertheless, the poor bone density in maxillary posterior region may affect osseointegration or cause implant displacement into maxillary sinus [10].…”
