Correlation between sleep disorder and dental implants

Past studies have linked excessive teeth grinding and clenching, also known as bruxism, with sleep apnoea. Now a Spanish study has investigated whether or not there is a higher frequency of prosthetic complications in patients with sleep apnoea.

Researchers looked at 172 patients who had taken part in a sleep study, 67 of whom had implant-supported prostheses. 30 prosthetic complications were identified across 16 patients, and 13 of these patients presented with obstructive sleep apnoea (OSA). This meant that 81% of those with a prosthetic complication also had OSA.

The most common complication was porcelain fracture, which occurred 14 times. This correlates with previous studies which have identified it as the most frequently reported technical complication. Other complications included screw/implant fracture, screw loosening and decementation. The average time for a complication to occur was 73 ± 65 months after the placement of the prostheses.

The study found that most of the complications were related to a fixed partial prosthesis, however it should also be noted that this was the most frequent type found in the study. Patients with the most severe form of OSA were found to have fracture-related complications. The authors note that further research is required to understand the risk of prosthetic complications amongst patients with sleep apnoea.

This study was published in the Journal of Implantology.
