CaPO4 Blasted Implants Inserted Into Iliac Crest Homologue Frozen Grafts

Abstract

In the last decade, some investigations have reported that the resorbable blast media surface (also named CaPO4 blasted implants [CaPO4-Bls]) has achieved excellent results. However, no report regarding CaPO4-Bls inserted into fresh frozen bone (FFB) is available. Thus, we planned a retrospective study on a series of CaPO4-Bls inserted into FFB to evaluate their clinical outcome. In the period between December 2003 and December 2006, 16 patients (10 females and 6 males, median age of 55 years) were operated on, and 76 CaPO4-Bls were inserted. The mean implant follow-up was 23 months. Implant diameter and length ranged from 3.25 to 4.5 mm and from 11.5 to 15 mm, respectively. Implants were inserted to replace 7 incisors, 11 cuspids, 31 premolars, and 27 molars. Only 1 out of 76 implants was lost (i.e., survival rate [SVR] = 98.7%), and no differences were detected among the studied variables. When peri-implant crestal bone resorption was used as an indicator of clinical success (i.e., success rate), it was possible to identify some variables that correlated with a better clinical outcome. Specifically, Cox regression showed that removable prosthetic restoration and longer implant length correlated with a statistically significant lower delta implant abutment junction (IAJ; i.e., reduced crestal bone loss) and thus a better clinical outcome. In this study, CaPO4-Bls had high survival and success rates, similar to those reported in previous reports of 2-stage procedures in nongrafted bone. CaPO4-Bls inserted into FFB are reliable devices, although greater marginal bone loss occurs when fixed prosthetic restorations and short implants are used.

In Vitro Analysis of the Efficacy of Ultrasonic Scalers and a Toothbrush for Removing Bacteria from Resorbable Blast Material Titanium Disks

“…Surface blasting is a process by which metal surfaces are treated with different types of materials (e.g., aluminum oxide, titanium dioxide) to provide an irregular surface 7 . Resorbable blast material (RBM) surface is prepared by sandblasting machined titanium with hydroxyapatite particles containing blast media or calcium phosphate ceramic media 8‐10 . The RBM surface has a higher surface roughness (2.14 μm) than machined surfaces (0.78 μm) 7 .…”

Removing bacteria from rough surface titanium discs with chlorhexidine and additional brushing with dentifrice

“…Nine RBM surface titanium discs (Neobiotech, Co., LTD, Seoul, Korea) measuring 9 mm in diameter and 3 mm in thickness were used to measure surface properties after burnishing with CHX cotton pellets. The RBM surface was prepared by sandblasting machined titanium with particles containing blast media. The whole of the top surface of the titanium discs was burnished with cotton pellets soaked with 0.12% CHX (Hexamedine Solution ® , Bukwang Pharm, Ansan, Korea) by a single operator (YK) for a total of 20 strokes within 20 s for the first group and 40 strokes within 40 s for the second group.…”
