Titanium implanthas been shown to be a predictable method for replacing missing teeth. Clinical studies revealed that implant failure rate in irradiated regionwas high. Many studies showed that modifications of implant surface could enhance implant osseointegration by improving cell attachment, cell growth and bone formation. Nevertheless, there were few studies investigating the effect of implant surface modification on osseointegration in irradiated bone. In the first experiment, the effect of fluoride-modified (FM) titanium surface on irradiated osteoblast attachment was assessed. The morphology and chemical composition of FM surface was assessed by SEM, AFM and XPS. Osteoblasts received 0Gy, 2Gy, 4Gy, 6Gy, 8Gy, 10Gy radiation. Cell number, fluorescence intensity and cell area of irradiated osteoblasts were assessed. The number of osteoblasts onFM surface was fewer than those on NF surface after 0Gy, 2Gy, 8Gy and 10Gy radiation. Cell area of osteoblasts on FM surface was less at 2Gy radiation but larger at 6Gy radiation than on NF surface. The fluorescence intensity of osteoblasts was also higher on NF surface than on FM surface after receiving 0Gy, 2Gy, 4Gy, 10Gy radiation. In the second experiment, an animal model was established to study the effect of radiation on osseointegration. Rabbits were divided into 15Gy and 30Gy radiation groups. Only the left leg was exposed to radiation, and the right leg was protected from radiation. Totally, 24 implants were inserted. Implant stability quotient (ISQ), bone volume to total volume (BV/TV), bone-to-implant contact (BIC), and bone growth rate were measured. After 15Gy and 30Gy of radiation, ISQ and BV/TV were significantly reduced. At week 3, 15Gy radiation group displayed slower bone growth rate comparing with the control side. Fluorochrome results showed that the 30Gy radiation side had a significantly slower apposition of new bone.In addition, BIC on30Gy radiation side was notablypoorer than that on 15Gy radiation side and on 30Gy control side. Based on the animal model, the third experiment investigated effects of calcium phosphate nanocrystals on implant osseointegration in irradiated bone. Titanium implants treated with nano-scale calcium phosphate (CaP) crystals served as the test group while ones with dual acid-etching only served as the control group. The left leg of rabbits received 15Gy radiation and implants were placed in the irradiated leg. Significant higher ISQ was detected in the nano-CaP group at week 12. The bone growth rate in nano-CaP group was more than doubled than the control group at both week 6 and week 9. The fourth experiment evaluated artifacts on micro-CT images caused by titanium dental implant. Implants were assigned into four groups: (1) implant only; (2) implant with covering screw; (3) implant with resin embedding; and (4) implant with covering screw and resin embedding. Each implant was scanned by micro-CT at 3 angulations. Implant angulation was the most determining factor followed by resin embedding. Minimal metallic artifacts were obtainedin non-embedded implants with its axis paralleling to X-ray. DOI: 10.5353/th_b5312315 Subjects: Osseointegration Dental implants

Download or read book Principles of Bone Regeneration written by Jona J. Sela and published by Springer Science & Business Media. This book was released on 2012-03-13 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: Principles of Bone Regeneration is a timely publication that addresses the modern aspects of bone healing and repair. This exciting new volume details the convergence of the different experimental and clinical approaches designed for the study and treatment of bone healing in its diverse forms and under varying conditions. Bone healing is affected by a multitude of genetic, environmental, mechanical, cellular and endocrine variables which eventually lead to changes in gene expression that enhance the guided action of osteoblasts (and chondroblasts) to lay down bone that restores, or even improves, the skeletal load bearing capacity. Recent breakthroughs in understanding the regulatory aspects of bone formation and resorption, in both research and clinical arenas offer new modalities to induce, enhances and guide repair processes in bone for the benefit of millions of patients with conditions such as nonunion fractures, critical size defects, orthodontic tooth movement, periodontal bone loss, intraosseous implants and deformed bones.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Background: Among the modifications in the sense of improving tissue response, surface treatment of implants has received more attention and is one of the most researched topics. Since the first portion of an implant to interact with the patient's tissues after implantation is the surface of the implant where direct contact occurs with the blood and consequently with its cellular components and growth factors. Aim: The aim of the present histologic animal study was to analyze whether roughness of the titanium surface can influence and/or stimulate the bone growth in defects filled with the blood using a rabbit tibia model. Material and Methods: Forty sets (implant and abutment), dental implant (3.5 mm in diameter and 7 mm in length) plus healing abutment (2.5 mm in diameter) were inserted in the tibiae of 10 rabbits. Moreover, twenty titanium discs were prepared. The abutment and discs were treated by 4 different methods and divided in 4 groups: (group A) machined abutments (smooth); (group B) double acid etching treatment; (group C) treatment with blasting with particles of aluminum oxide blasted plus acid conditioning (group D) treatment with through blasting with particles of titanium oxide plus acid conditioning. The discs were used to characterize the surfaces by a profilometer and scanning electronic microscopy. Results; After 8 weeks, the new bone formation around the sets of the samples were analyzed qualitative and quantitatively in relation to bone height from the base of the implant and presence of osteocytes. In the group C (1.50 u00b1 0.20 mm) and group D (1.62 u00b1 0.18 mm) showed bone growth on the abutment with higher values in compare to group A (0.94 u00b1 0.30 mm) and B (1.19 u00b1 0.23 mm), with significant difference between the groups (P

Available in PDF, EPUB and Kindle. Book excerpt: Bone quality is one of the most important factors in the successful osseointegration of dental implants. However, the concepts of bone quality and compromised bone have never been well defined in the field of implant dentistry. To provide a clear definition of these terms, the contributors to this volume have compiled data from almost two decades of experimental and case studies, resulting in a comprehensive review of the current knowledge regarding the placement of implants in compromised bone. The book also presents specific considerations for placing implants in different types of compromised bone, such as aged, underdeveloped, and irradiated bone. A useful work of reference for implant students, practicing implant clinicians, and implant-oriented researchers.

Available in PDF, EPUB and Kindle. Book excerpt: The objective of this study was to evaluate the in vivo performance of the novel press-fit dental implant fabricated via electron beam melting (EBM, Southern Methodist Univ.) and compare it to a commercially-available porous-coated press-fit dental implant (Endopore, Innova Corp.). Twelve cylindrical shaped implants 3 mm in diameter x 5 mm long were made by EBM (Southern Methodist Univ.) using Ti6Al4V ELI alloy. Twelve commercial implants (Endopore, Innova Corp.) of the same geometry were used as controls. Samples were implanted in rabbit tibia and retrieved six weeks postoperatively. Six specimens from each implant type were embedded undecalcified, sectioned, and stained with toluidine blue (Sigma) for histomorphometry analysis. Bone-to-implant contact (BIC) was measured. On the six remaining samples from each implant type, the mechanical properties were evaluated by pushout test on a material testing machine. The samples were loaded at a loading rate of 1 mm/min. The pushout strength was measured and the apparent shear stiffness was calculated. The results were analyzed with a paired-t test. The histology shows osteointegration of surrounding bone with both implant types. Bone was found to grow into the porous space between the beads. Both the Endopore (Innova Corp.) and the EBM (Southern Methodist Univ.) showed similar BIC. The mean BIC for the Endopore (Innova Corp.) and EBM (Southern Methodist Univ.) implant were 35 " 6% and 32 " 9%, respectively. It failed to reach statistical significance (p> 0.05). The peak pushout force for Endopore (Innova Corp.) and EBM (Southern Methodist Univ.) implants were 198.80 " 61.29 N and 243.21 " 69.75 N, respectively. The apparent shear stiffness between bone and implant for the Endopore (Innova Corp.) and EBM (Southern Methodist Univ.) implants were 577.36 " 129.99 N/mm; and 584.48 " 146.63 N/mm, respectively. Neither the peak pushout force nor the apparent shear stiffness of the implants was statistically different between the two groups (p> 0.05). The results suggest that the implants manufactured by EBM (Southern Methodist Univ.) perform equally well as the commercial implant Endopore (Innova Corp.) in this current animal model.
