Resin composite (Z250, 3M, St Paul, MN) was bonded in bulk with various degrees of cure into Class 2 preparations in extracted human molar teeth. Two control groups consisted of a highly-cured incrementally-placed group and a non-fatigued low- cure group. The restorations were subjected to 1000 thermal-cycles and 500,000 fatigue cycles from 18 to 85 Newtons using a stainless-steel sphere. Marginal integrity was evaluated using visual rating (ridit analysis) and microleakage. The degree of conversion had a significant effect on marginal defects but not on microleakage. Water had a significant dissolving effect on gingival margin integrity at very low degrees of conversion. Gingival marginal defects were maximized at 25% of maximum conversion and 3% of maximum hardness. There was no overall significant effect of thermal-mechanical stressing on marginal defects or microleakage. A recommended lower limit of gingival margin acceptability in a bulk-filled resin composite restoration was created by 80% of maximum conversion, 73% of maximum hardness and approximately 70% of maximum flexural strength and modulus in the gingival marginal area.

This book covers both basic scientific and clinically relevant aspects of dental composite materials with a view to meeting the needs of researchers and practitioners. Following an introduction on their development, the composition of contemporary composites is analyzed. A chapter on polymerization explains the setting reactions and light sources available for light-cured composites. The quality of monomer-to-polymer conversion is a key factor for material properties. Polymerization shrinkage along with the associated stress remains among the most challenging issues regarding composite restorations. A new classification of dental composites is proposed to offer more clinically relevant ways of differentiating between commercially available materials. A review of specific types of composites provides an insight into their key issues. The potential biological issues of dental composites are reviewed in chapters on elution of leachable substances and cariogenicity of resin monomers. Clinical sections focus on material placement, finishing procedures, and the esthetics and clinical longevity of composite restorations. Bonding to tooth tissues is addressed in a separate chapter, as is the efficiency of various composite repair methods. The final chapter discusses future perspectives on dental composite materials.

This handbook describes several current trends in the development of bioceramics and biocomposites for clinical use in the repair, remodelling, and regeneration of bone tissue. Comprehensive coverage of these materials allows fundamental aspects of the science and engineering to be seen in close relation to the clinical performance of dental and orthopaedic implants. Bioceramics and biocomposites appear to be the most dynamic area of materials development for both tissue engineering and implantable medical devices. Almost all medical specialties will continue to benefit from these developments, but especially dentistry and orthopaedics. In this Handbook, leading researchers describe the use of bionanomaterials to create new functionalities when interfaced with biological molecules or structures. Also described are technologies for bioceramics and biocomposites processing in order to fabricate medical devices for clinical use. Another important section of the book is dedicated to tissue regeneration with development of new matrices. A targeted or personalized treatment device reduces drug consumption and treatment expenses, resulting in benefits to the patient and cost reductions for public health systems. This authoritative reference on the state-of-the-art in the development and use of bioceramics and biocomposites can also serve as the basis of instructional course lectures for audiences ranging from advanced undergraduate students to post-graduates in materials science and engineering and biomedical engineering.

Composite resins are types of synthetic resins which are used in dentistry as restorative material or adhesives. Synthetic resins evolved as restorative materials since they were insoluble, aesthetic, and insensitive to dehydration and were inexpensive. This book presents topical research in the study of resin composites, including water immersion and impact damage effects on resin composites; fabrication and evaluation of bioactive dental composites; nanostructured organosilicate composites; the electromagnetic properties of a composite made of metal particles dispersed in resin and posterior composite resin restoration.
