In this work, the properties of poly(methyl methacrylate) (PMMA)/alumina composites prepared by melt blending were evaluated. Two types of alumina were used: one, that was synthesized (ALS) by the combustion reaction method, and the other that is commercially available (ALC). Extrusion proved to be a good processing technique for obtaining PMMA/alumina composites. PMMA/alumina composites containing ALC presented higher alumina average particles size. The addition of alumina to PMMA substantially decreased the wear index and increased the scratch resistance. The mechanical properties of the composites containing ALS were similar to those containing ALC. The storage modulus ( E′) increased with the addition of alumina to PMMA. The zero shear viscosity ( η0) values of the composites containing ALC were higher than those of the composites containing ALS.

Dimethyl Itaconate Modified PMMA ‐ Alumina Fillers Composites With Improved Mechanical Properties

PMMA poly(methyl methacrylate) has a large spectrum of uses as bone cements, in dentistry as denture base materials and other industrial applications. One of the main drawbacks of these materials is the residual monomer that is proven allergen and irritant. It was shown that addition of dimethyl itaconate (DMI) to the PMMA denture base systems decrease the quantity of residual monomer but, also deteriorate mechanical properties. The addition of alumina fillers in the PMMA/DMI produced composite materials results in improved mechanical properties compared with pure PMMA and additionally reduces the level of residual monomer in the composition.

“…Another approach in improving the mechanical parameters of PMMA-based cements was developed by the addition of fillers in the form of alumina nanoparticles having different shapes and sizes [18]. The reinforcements were based on alumina nanoparticles having either a spherical shape or whiskers with a length to diameter ratio of 100.…”

The history of acrylic bone cement comprise a long period of time, Sir John Charnley being considered the founder of modern artificial joint replacement, as he started to develop the cementing in the late 1950s. Acrylic bone cements (ACB) are polymer-ceramic composites based on polymethyl metacrylate (PMMA), widely used in orthopaedics as suture materials and fixation devices. The main features of these materials are: 1) biocompatibility and ability to support new bone growth (osteoconductive) and 2) bioactivity (ability to form a calcium phosphate layer on its surface). The main function of the cement is to serve as interfacial phase between the high modulus metallic implant and the bone, thereby assisting to transfer and distribute loads. During years of follow up, cemented prosthesis with acrylic bone cements (ABC) demonstrated a good primary fixation and load distribution between implant and bone, along with the advantage of fast recovery of the patient. However, several problems are still persisting, as the orthopedic acrylic bone cements have to meet several medical requirements, such as low values of maximum cure temperature in order to avoid thermal necrosis of the bone tissue during the setting time, appropriate setting time (so that cement does not cure too fast or too slowly) and high values of compressive strength in order to withstand the compressive loads involved by normal daily activities. Generally, the improvement mechanical properties can be realized in three directions: 1) by searching alternative material to PMMA acrylic bone cements; 2) chemical modification of PMMA; and 3) the reinforcement of PMMA by adding different bioactive particles, antimicrobials, vitamins. The aim of this rewiew is to explore the development of bone cements in the last decade, to highlight the role of bone cement additives with respect to mechanical properties and limitations of polymethylmethacrylate in orthopaedic surgery. The behavior of antibiotic-loaded bone cement is discussed, compared with other alternative additives including nanofillers, together with areas of research that are now open to explore new insights and applications of this well known biomaterial.
