dc.description.abstract | Bruxism is an unconscious, involuntary and sustained motor activity that results in excessive
teeth grinding or jaw clenching that could affect patients’ implants and rehabilitations. The aetiology
for bruxism remains unknown, but it is known to involve multiple factors. The literature lacks studies
on the possible effect of implant morphology on the resistance of the bone-implant osseointegrated
interface when bruxism is present. Our objective is to assess the mechanical response of the
bone-implant interface in bruxist patients whose implant prostheses are subjected to parafunctional
cyclic loading over a simulated period of 10 years. A comparison was carried out between two
implant types (M-12 and Astra Tech), and a pattern of bone loss was established considering both
the stress state and the cortical bone surface loss as the evaluation criteria. Numerical simulation
techniques based on the finite element analysis method were applied in a dynamic analysis of the
received forces, together with a constitutive model of bone remodelling that alters the physical
properties of the bone. The simulated cortical bone surface loss at the implant neck area was 8.6%
greater in the Astra implant than in the M-12 implant. Compared to the M-12 implant, the higher
sustained stress observed over time in the Astra implant, together with the greater cortical bone
surface loss that occurred at its neck area, may be related to the major probability of failure of the
prostheses placed over Astra implants in bruxist patients. | es |
