In this paper, voxel-based finite element models were built based on the micro-CT images of human cadaveric mandible specimens before and after implant placement. The computed strain distribution patterns qualitatively agreed with our experimental results. In our prior computational work, voxel-based models were built based on the micro-CT images, and the strain in bone under implant loading was computed using finite element method (FEM) ( Mao et al., 2019). The strain concentration in the thinner buccal plate was more substantial than that in the thicker lingual plate. High strain appeared at bone-implant contact regions, as well as in buccal and lingual (tongue-side) bone plates although these regions were not directly in contact with implants. In our prior experimental work, strain in alveolar bone under implant loading was mapped using mechanical testing coupled with micro X-ray computed tomography (micro-CT) and digital volume correlation ( Du et al., 2015 Zhou et al., 2020). Mechanics of bone-implant complex is one of the factors that contribute to implant stability and success ( Brunski, 1992 Leucht et al., 2007 Wazen et al., 2013). One risk of immediate implant placement is buccal (lip-side) bone resorption, of which the mechanisms are still not clear ( Chen and Buser, 2014, 2009 Kan et al., 2010).

Immediate implant placement is a treatment method to install dental implants immediately after tooth extraction, aiming to preserve the alveolar bone dimensions after tooth loss. The results indicate that the distance from implant to the buccal plate can affect the mechanical stimuli in bone, especially in the buccal plate, which may subsequently affect the bone remodeling process and buccal bone resorption. The strain in lingual bone also deceased when the implant was moved from the center of the alveolar socket towards the lingual or buccal plate. The computed strain in the buccal bone decreased when the implant was placed away from the buccal plate. The implant position was then virtually changed in the models to be placed lingually or buccally. The average values of maximum principal strain in the buccal and lingual ROIs were in good agreement with those measured using mechanical testing coupled with micro-CT and digital volume correlation. The strain concentration in the thinner buccal plates was more substantial than that in the thicker lingual plates. The computed results show high strain at the bone-implant contact locations and the buccal and lingual bone plates. In this work, voxel-based finite element models were built based on the micro-CT images of human cadaveric mandible specimens before and after implant placement. Bone-implant mechanics is one of the factors that contribute to implant stability and success.
