Available in PDF, EPUB and Kindle. Book excerpt: Apesar do titânio e suas ligas serem amplamente empregadas na implantodontia e os resultados das experiências clínicas comprovarem que estes materiais apresentaram excelente biocompatibilidade, existem dúvidas quanto às propriedades físico-químicas ideais das superfícies dos implantes de titânio para se obter uma osseointegração adequada. Todavia, os padrões para definir as propriedades superficiais dos implantes odontológicos ainda não estão definidos na literatura. Estas características são importantes, uma vez que a osseointegração é fortemente dependente da ligação das células com a superfície do implante. Este trabalho tem como objetivo analisar três processos subtrativos utilizados no tratamento da superfície de implantes osseointegráveis de titânio comercialmente puro a saber: abrasão - jateamento, erosão ataque químico e combinação das duas. Estes métodos permitem avaliar as propriedades físicas e químicassuperficiais de cilindros de titânio tratados através destes processos tais como: morfologia superficial, topografia e molhabilidade (ângulo de contato). Foi possível, também, identificar os parâmetros e métodos vinculados que otimizam as condições superficiais para este fim.

Download or read book Evaluation of Four Different Titanium Surface Treatment on the Bone Healing in Defects Filled Only with Blood Clot a Experimental Animal Study written by Leticia Pu00e9rez and published by . 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

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

Book excerpt: Recently, great attention has been paid to materials that can be used in the human body to prepare parts that replace failed bone structures. Of all materials, Ti-based materials are the most desirable, because they provide an optimum combination of mechanical, chemical, and biological properties. The successful application of Ti biomaterials has been confirmed mainly in dentistry, orthopedics, and traumatology. Titanium biocompatibility is practically the highest of all metallic biomaterials; however, new solutions are being sought to continuously improve their biocompatibility and osseointegration. Thus, the chemical modification of Ti results in the formation of new alloys or composites, which provide new perspectives for Ti biomaterials applications. This book covers broad aspects of Ti-based biomaterials concerning the design of their structure, mechanical, and biological properties. This book demonstrates that the new Ti-based compounds and their surface treatment provide the best properties for biomedical applications.

Abstract: Titanium and its alloys have been widely used as materials in biomedicine and in particular, for dental implants, and one main reason is their unique ability to osseointegrate with the host bone. This phenomenon forms a strong bone-to-implant bonding. The rate and quality of osseointegration of a titanium dental implant depends heavily upon its surface properties. Over time, various surface treatment methods have been developed to further improve osseointegration of titanium-based biomaterials. This PhD thesis focuses on promising surface treatment methodology: surface charge modification. A negative charge has been known to promote the osseointegration of titanium biomaterials. Before the current work there was no practical approach to induce negative charge on titanium surfaces. The goal was to find such a practical technique. The current investigations revealed that sandblasting, a commonly used surface treatment method, can generate a negative charge on the surface of titanium, and also titanium alloy and stainless steel micro-implants, due to the triboelectric effect. Stainless steel doesn't osseointegrate. The basic methodology of these studies was to sandblast titanium and measure the amount and polarity of the static charge on titanium surfaces. The effects of several important parameters were evaluated, including the sandblasting material, the size of the blasting grits, and the shape of the titanium material. Statistical analysis was performed on the results of the static charge measurements. In addition, the contamination of the titanium sandblasting was also evaluated. The results of the current studies suggested that sandblasting could generate static charges on titanium and stainless steel surfaces. However, such charges gradually dissipate into the atmosphere. The amount, polarity, and the decay rate of the charge depend on many factors tested in the experiments. These results might explain the beneficial of sandblasting on the osseointegration of titanium implants. Osseointegration has been traditionally attributed to its roughening effects. Moreover, the current studies may potentially lead to improved sandblasting techniques, becoming in mind that more research should be carried out.
