Study finds strong link between OSA and implant complications

Post a comment by Dental Tribune International

VITORIA, Spain: There has been increasing awareness of the reciprocal relationship between obstructive sleep apnoea (OSA) and dental problems, for example sleep bruxism and a higher clench index. However, few studies have investigated the role of OSA in the occurrence of technical failure in fixed prostheses, especially those that are implant-borne. A Spanish study has now found that over 80 per cent of the patients with OSA experienced implant problems—suggesting a potentially strong correlation between the sleep disorder and implant complications.

Aiming to analyse the frequency of prosthetic complications in implant-borne prostheses, a group of researchers from Vitoria investigated implant failure in 67 patients. They identified 30 complications affecting 22 prostheses among 16 patients. Of these, 13 also had OSA (81 per cent).

Complications included porcelain fracture (14 events), screw/implant fracture (eight events), screw loosening (three events) and de-cementation (five events). According to the researchers, most of the complications occurred in the posterior segments. Moreover, the highest apnoea–hypopnea index score, and thus the severity of OSA, was identified in patients with a fracture complication related to an implant, a screw or a porcelain crown, the study showed. The average time for problem occurrence was 73 months after insertion of the implant.

Based on the results, which suggest a strong link between OSA and implant complications, the researchers noted that future studies should explore the correlation further in order to better understand the risk factors and frequencies of these occurrences.

The study, titled “Frequency of prosthetic complications related to implant-borne prosthesis in a sleep disorder unit”, was published in the February issue of the Journal of Oral Implantology.
