New data demonstrates a strong correlation between obstructive sleep apnoea (OSA) and complications with previously implanted oral prosthetics.
OSA is a sleep disorder in which breathing repeatedly starts and stops during sleep. OSA has frequently been linked to sleep bruxism, a condition where a person clenches and tightens the jaw creating excessive grinding of the teeth during sleep. Both conditions are linked to several health issues; however, no previous studies have linked OSA to prosthetic complications.
In a study published last month in the Journal of Oral Implantology, researchers from OSI Araba University Hospital in Victoria, Spain, investigated how OSA affects implant-borne prostheses.
The researchers found that 16 of the 67 patients included in their study experienced prosthetic complications, 13 of whom had OSA. Among these 16 individuals, there were 22 prostheses and a total of 30 issues. Complications consisted of porcelain fracture, fracture of the screw/implant, loosening of the screw, and decementation. The average time for a complication to occur was six years and one month post-implantation.
During the study, the researchers also noted a strong relation between individuals who suffer from OSA and those who suffer from bruxism.
They noted: “Among dental practitioners, there has been increasing awareness of the reciprocal relationship between obstructive sleep apnoea (OSA) and dental diseases. One new aspect of interest would be the occurrence of technical complication in fixed prosthodontics.”
