Summary

Excessive mechanical forces can cause complications of dental implants and their suprastructures (crowns and bridges), and can possibly be destructive for the bone and soft tissues around the implants. Sleep bruxism (grinding and clenching of the teeth during sleep) is considered as an important source of mechanical forces in the oral environment. Therefore, in this study, the investigators will investigate whether sleep bruxism is associated with implant and peri-implant complications.

Conditions

• Dental Implant Complications
• Sleep Bruxism

Interventions

Type	Name	Description
DEVICE	Electromyographic recording of temporalis muscle activity during sleep	Electromyographic recording of temporalis muscle activity during sleep. In total, 9 sleep recordings will be done at the home setting of each participant. 1. 3 recordings after the baseline visit 2. 3 recordings 6 weeks after the baseline visit 3. 3 recordings one year after the baseline visit
RADIATION	Vertical bitewing radiograph	An intraoral vertical bitewing radiograph will be performed with the assistance of individually modified plate positioning devices at each visit (in total 8 visits during the 2-year follow-up period).
OTHER	Collection of biofilm sample	Collection of peri-implant intrasulcular biofilm sample for DNA analysis of the biofilm composition. In total, samples will be collected three times: 1. At the baseline visit 2. Three months after the baseline visit 3. One year after the baseline visit
