Obstructive Sleep Apnea (OSA) can lead to prosthetic complications in Dental Implants

According to a recent study in the Journal of Oral Implantology, there is a strong correlation between OSA and oral prosthetic issues.

This study shows that 81% of patients with OSA experienced complications with their prostheses. This is an important finding as there are no previous studies that have shown an association between OSA and Prosthetic complication. Obstructive sleep apnea (OSA) is a sleep disorder in which breathing repeatedly starts and stops during sleep. OSA is believed to be related  to sleep bruxism, Both conditions are linked to several health issues. Recent data shows a strong correlation between OSA and complications with previously implanted oral prosthetics.

Researchers at OSI Araba University Hospital in Victoria, Spain published a study in the Journal of Oral Implantology that investigated how OSA affects implant-borne prostheses. 67 patients were exmanined for  frequency with which a complication occurred and the type of complication. Interestingly, the researchers found a high instance of complications related to OSA.

Of the 67 patients, 16 experienced complications; 13 of which had OSA. Among these 16 patients with complications, there were 22 prostheses with a total of 30 issues. The complications were porcelain fracture, fracture of the screw/implant, loosening of the screw, and decementation. They found that the average time for a complication to occur was 73 months post-implantation.

A strong relation between individuals who suffer from OSA and those who suffer from bruxism was also noted. This shows that people suffering from OSA and/or bruxism have a more difficult time with successful prosthetic implantation.

The researchers note that, “Among dental practitioners, there has been increasing awareness of the reciprocal relationship between obstructive sleep apnea (OSA) and dental diseases. One new aspect of interest would be the occurrence of technical complication in fixed prosthodontics.”

Given that the success rate of implants is reported to be between 92% and 97%, there is a strong correlation between OSA and prosthetic complications. The researchers believe that additional investigations are necessary to establish a correlation between OSA and implant complications.
