Surface Modification Techniques

This manuscript reviews about titanium surface modification techniques for its application in orthopaedic and dental implants. There are a few limitations in the long term prognosis of orthopaedic and dental implants. Poor osseointegration with bone, periimplant infection leading to implant failure and short term longevity demanding revision surgery, are to mention a few. Micro- and nanoscale modification of titanium surface using physicochemical, morphological and biochemical approaches have resulted in higher bone to implant contact ratio and improved osseointegration. With recent advances in micro, nano-fabrication techniques and multidisciplinary research studies focusing on bridging biomaterials for medical applications, TiO2 nanotubes have been extensively studied for implant applications. The need for titanium implant surface that can closely mimic the nanoscale architecture of human bone has become a priority. For such purpose, TiO2 nanotubes of different dimensions and architectural fashions at the nanoscale level are being evaluated. This manuscript discusses in brief about the in-vitro and in-vivo studies on titanium surface modification techniques. This manuscript also addresses the recent studies done on such nanotubular surfaces for the effective delivery of osteoinductive growth factors and anti bacterial/ anti inflammatory drugs to promote osseointegration and prevent peri-implant infection.

Bone Response

The dental implant is one of the appropriate instances of the different dental materials and their application, which is the combined procedure of technology and science in physics, biomechanics, and surface chemistry from macroscale to nanoscale surface engineering and manufactured technologies. In recent decades, biomaterials in implant therapy promote bone response and biomechanical ability, which is long-term from surgical equipment to final prosthetic restoration. Biomaterials have a crucial role in rehabilitating the damaged structure of the tooth and supplying acceptable outcomes correlated with clinical performance. There are some challenges in implantation such as bleeding, mobility, peri-implant infections, and the solution associated with modern strategies which are regarded to biomaterials. Various materials have been known as promising candidates for coatings of dental implants which contain polyhydroxyalkanoates, calcium phosphate, carbon, bisphosphonates, hydroxyapatite, bone stimulating factors, bioactive glass, bioactive ceramics, collagen, chitosan, metal and their alloys, fluoride, and titanium/titanium nitride. It is pivotal that biomaterials should be biodegradable; for example, polyhydroxyalkanoates are biodegradable; also, they do not have bad effects on tissues and cells. Despite this, biomaterials have important roles in prosthetic conditions such as dental pulp regeneration, the healing process, and antibacterial and anti-inflammatory effects. In this review study, the role of biocompatible materials in dental implants is investigated in in vitro and in vivo studies.

SummarySeveral “in vitro” and “in vivo” studies indicate that heparin administration may affect platelet function. In this study we investigated the effects of prophylactic heparin on thromboxane (Tx)A2 biosynthesis “in vivo”, as assessed by the urinary excretion of major enzymatic metabolites 11-dehydro-TxB2 and 2,3-dinor-TxB2. Twenty-four patients who were candidates for cholecystectomy because of uncomplicated lithiasis were randomly assigned to receive placebo, unfractionated heparin, low molecular weight heparin or unfractionaed heparin plus 100 mg aspirin. Measurements of daily excretion of Tx metabolites were performed before and during the treatment. In the groups assigned to placebo and to low molecular weight heparin there was no statistically significant modification of Tx metabolite excretion while patients receiving unfractionated heparin had a significant increase of both metabolites (11-dehydro-TxB2: 3844 ± 1388 vs 2092 ±777, p <0.05; 2,3-dinor-TxB2: 2737 ± 808 vs 1535 ± 771 pg/mg creatinine, p <0.05). In patients randomized to receive low-dose aspirin plus unfractionated heparin the excretion of the two metabolites was largely suppressed thus suggesting that platelets are the primary source of enhanced thromboxane biosynthesis associated with heparin administration. These data indicate that unfractionated heparin causes platelet activation “in vivo” and suggest that the use of low molecular weight heparin may avoid this complication.
