Several clinical studies is associated with loss of marginal bone or even loss of the osseointegration around the implant.
More recently, a review on animal studies found differences in the histological features between plaque- and overload-induced peri-implant bone loss.
This lack of sound evidence is the consequence of mainly two factors.
First, up to the present time, there is no study with the specific design to assess the effect of bruxism on dental implants.
However, as yet, causative relationships between mechanical loading and peri-implant biological complications have not been established, due to a general lack of clinical studies with an appropriate design to assess the effect of excessive loading on dental implants, Animal experimental data suggest that high loading of clinically stable dental implants is associated with marginal bone loss in the case of inadequate plaque removal, while when plaque control is sufficient, this loading might lead to an increase of bone density around the implant.
Bruxism Research Paper
Investigating the time-dependent associations between mechanical forces (such as those attributed to SB), the composition of microbial communities and host response will enhance our insight into the pathogenesis of peri-implant disease.
Studies that have included bruxism as one of the factors contributing to complications show a large variation in terms of both the technical and the biological outcomes of implant treatments, so that their comparability is compromised.
On the basis of the assumption that SB can lead to complications, clinicians are so far instructed to be cautious, and are guided by expert opinions regarding practical aspects of implant treatments in patients with (suspected) bruxing behaviour.
To describe the protocol of a prospective cohort study designed to answer the question: ‘Is sleep bruxism a risk factor for (peri-)implant complications? Our study is a single-centre, double-blind, prospective cohort study with a follow-up time of 2 years.
Ninety-eight participants fulfilling inclusion criteria (planned treatment with implant-supported fixed suprastructure(s) and age 18 years or older) will be included.
