Buccal Bone Wall Thickness Dictates the Extent of Vertical Buccal Bone Loss Following Implant Placement: A Preclinical Study.

ABSTRACT:

Aim

To assess buccal vertical bone resorption following implant placement in healed sites with varying buccal bone wall thicknesses.

Materials and methods

In 11 miniature pigs, three tapered hybrid titanium implants were placed per hemi-maxilla in healed bone. Sites were randomised into three groups based on buccal bone wall thickness: G1 (< 1.0 mm), G2 (1.0-1.5 mm) and G3 (> 1.5 mm). Animals were euthanised at 24 h and 2, 4 or 8 weeks. Histological and histometric analyses were performed. The primary outcome was the vertical distance from the transition point (TP) between the machined and moderately rough implant surfaces to the first bone-to-implant contact (fBIC).

Results

Healing was uneventful. At 2 weeks, all groups showed buccal resorption, although G3 exhibited
