Accidental migration of dental implant into the nasal cavity: Spontaneous expulsion through the nose

Abstract

Implant migration into the nasal fossa is a rare complication and it requires extraction by anterior rhinoscopy. We report a clinical case of placement of short dental implants, fixed or intruded in the nasal fossa floor, which was aspirated by the patient and spontaneously expelled a few days later. To the best of our knowledge, there have been no reports of spontaneously expulsion through the nasal cavity. Key words: Dental implant, nasal cavity, accidental migration.

Accidental displacement of a dental implant into the Nasal Cavity: Report of a rare case

“…Implant migration into paranasal sinuses can cause pain, fungus-related infections, and sinusitis. 6 In all reported cases of implant migration into the nasal cavity, patients have symptoms like nasal discomfort, nasal pain, and purulent discharge; [3][4][5][6] on the contrary, the patient presented in this study did not experience any discomfort. The reason for being asymptomatic is uncertain.…”

“…This might be due to the dentist's lack of skill and experience, inappropriate bone quality, excessive implant tapping, untreated perforation of the sinus lining (Schneiderian membrane), or application of too much force. 4,[6][7][8][9] Cases of implant migration into maxillary sinus are repeatedly reported, but implant displacement into other anatomical spaces like nasal cavity is scarce. 2 We reported a case in which the implant was migrated into the maxillary sinus due to inappropriate insertion and blunder of the dentist.…”

“…3,6 While in the other two reports, implants had moved directly from the oral cavity to the nasal cavity by perforating the nasal floor. 4,5 Although implant treatment itself is more prevalent in females, the current literature suggests that the prevalence of this complication is higher in males compared to females. However, this conclusion cannot be considered robust due to the low number of reported cases.…”

“…5,6 However, in two studies it has been mentioned that the migrated implant is expelled spontaneously. 3,4 In the study of Sanchis & Díaze, the implant accidentally was thrown off through the nose. 4 But, in van de Loo et al's study, the implant disappeared after being detected in the CBCT.…”

“…3,4 In the study of Sanchis & Díaze, the implant accidentally was thrown off through the nose. 4 But, in van de Loo et al's study, the implant disappeared after being detected in the CBCT. 3 Most probably, the implant entered the gastrointestinal tract subconsciously and was thus excreted.…”
