Influence of the Buccal Bone Crest Width on Peri-Implant Hard and Soft Tissues Dimensions: A Histomorphometric Study in Humans
Implant Dent. 2018 Aug;27(4):415-423
The aim of this significant histomorphometic study in humans, engaging well known professionals from 3 continents, was to evaluate the influence of the width of the residual wall in bone reabsorption, comparing in a split-mouth protocol the remodeling of 1 mm walls (test sites) and 2 mm walls (control sites) 3 months after bone placement. No differences in soft tissue dimensions as well as hard and soft tissues levels were found between the 2 groups, except for the horizontal resorption, which resulted higher at the 2 mm residual bone. From a clinical point of view these results confirm that implant outcome can be predictable even when the buccal wall is thinner than 2 mm, that is the limit previously recommended by a wide literature. In addition, the stunning histologic images demonstrate that ZirTi surface is an optimal substrate for new bone apposition, with a final 69% BIC (Bone-Implant Contact) and 75.8% in control sites at 3 months.
