http://www.quintpub.com/journals/octe/abstract.php?article_id=3594 NettetThis study was implemented as an in vitro study. The sample was composed of fresh bovine ribs which were suitable for imitating the soft bone. The narrow part of the rib was supposed to match bone type 4 at closest accordance to the Lekholm and Zarb classification and selected for the study procedures [10,11].

Nettet1. mar. 2024 · In this classification, the volume and structural characteristics of the bone tissue are assessed based on panoramic and peri-apical radiographs and the surgeon’s tactile perception of bone hardness3. The primary stability of the implant is also an important parameter to be assessed. NettetThe mean bone density values in Hounsfield unit (HU) were recorded using Simplant for both the simulated implant areas and the trabecular bone width. We classified the edentulous alveolar ridge and bone quality according to a classification based on Lekholm and Zarb (1985). Results: Incisors had higher bone densities than canines.
Nettetbone, the nerve injury can occur as the result of over penetration of the drill owing to low resistance of the spongy bone; this can lead to slippage of the drill even by experienced surgeons. Lekholm and Zarb [12] classify quality of residual alveolar bones into four types: type 1 = large homogenous cortical bone; type 2 = thick cortical
