What is it about?

The Rectangular Block Implant is a novel design dental implant that has a surface area of conventional medium sized implants, yet is only 5.25 mm in depth. It is a "horizontally" oriented implant, designed to designed to take advantage of the horizontal length of the remaining resorbed alveolar ridge.

Why is it important?

The Rectangular Block Implant is unique in that its dimensions allow it to be placed under conditions of low bone volume, thereby avoiding complex grafting procedures: - its flat surfaces allow unique stress distribution of the applied loads into the surrounding bone. The result is a "short" implant with a large surface area, no need for ridge augmentation and the ability to withstand the loads applied in the posterior dentition.


This publication is one perspective of the biomechanical profile of the Rectangular Block Implant. Further experiments using ISO 14801 protocols with the Rectangular Block Implant have shown a potent reduction of strains generated even at 1000N, to within known physiological limits. The overall picture is that the rectangular horizontally oriented block implant maximises the available bone volume of the resorbed ridge, is able to withstand the maximal human masticatory loads and keep the generated strains within physiological limits.
