Influence of short implants geometry on primary stability.
2018
Background A correct design is needed in short implants to improve primary stability (PS) in low quality bone. This study aimed to compare PS of double thread and single thread short implants. Material and Methods Thirty implants with single thread design (PHI/SHORT-I) and 30 implants with double thread design (PHIA/SHORT-I) (Radhex®, Inmet-Garnick S.A., Guadalajara, Spain) were placed in 30 randomly selected bovine ribs. PS was assessed in implant stability quotients (ISQ) and periotest values (PV) with Osstell™ and Periotest® devices, respectively. Computed tomographies of the ribs were taken and bone quality was evaluated in Hounsfield Units (HU) using Ez3D Plus software (Vatech Co., Kor…
Study of available bone for interforaminal implant treatment using cone-beam computed tomography
2008
Objectives: To analyze the availability of bone in the interforaminal region and to demonstrate the variation in diagnosis between panoramic x-ray and cone-beam computed tomography (CBCT). Material and methods: In 50 patients and in 5 areas of each, a series of parameters concerning available bone were measured on both the panoramic and the CT images. Results: Panoramic images underestimate the vertical and horizontal measurements when compared with CBCT. Regarding implant treatment, the interforaminal region presents the same remaining bone height throughout its full extent, the correlation between one side of the midline and the other was highly significant for all the parameters studied,…
