The biomechanical profile of an osseo-integrated rectangular block implant: A pilot in vivo experimental study

Abstract

Objective: A novel implant design, the rectangular block implant (RBI), was investigated as a possible solution to the restoration of the posterior resorbed ridge. Aim: To maximally load test the osseo-integrated RBI in shear and tensile loads and relate these findings to known human masticatory loads as biomechanical proof of the study concept. Materials and methods: Twelve RBIs were design-manufactured and placed into posterior mandibular saddles in 3 mature greyhound dogs.—2 per left and right. After 12 weeks of healing, osseo-integration was confirmed using resonance frequency analysis (RFA) and wrench torque tests. Three bone blocks each with two RBIs were dissected and mounted in acryl..
