Deskripsyon
The detrimental impact of resin composite polymerization shrinkage on restoration interface quality and stability has been recognized since the early use of this material is still one of the major drawbacks in adhesive dentistry, as it frequently leads to loss of marginal integrity or enamel fracture. According to clinical studies, drawbacks such as postoperative sensitivity, marginal discoloration and possibly secondary caries are often associated with loss of marginal integrity in composite restorations occurred as a result of polymerization shrinkage. Various technological solutions were investigated, including improved filler technology; improved, novel matrix structure with reduced shrinkage; use of stress-decreasing compounds within the resin matrix; changes in light-initiation technology to increase curing depth; and use of sonic vibrations and energy to favor flow and adaptation of highly filled resin composite. To achieve optimal long term performance, the requirements will be first to manage polymerization stress buildup following restoration. Low-shrinking composites should help to avoid clinical problems that are commonly associated with composite restorations, such as post-operative sensitivity, enamel cracks, rapid discoloration and deterioration of restoration margins, early development of caries recurrence, with a new formula and improved sculptability SAREMCO has been successful in brilliantly further developing the leader product els extra low shrinkage. When using new simplified restorative systems featuring distinctive physicochemical characteristics, the potential impact of different parameters such as fatigue behavior and/or elastic modulus on restoration quality and behavior is unknown and justifies additional investigations. Instead of in vitro evaluations, consideration of a rather well-established clinical trials suggesting medium to long term observation periods to discriminately appraise the clinical performance of various operative protocols.
The project includes 30 patients. Most of the patients have been recruited from the Istanbul Medipol University Dental Clinics in Istanbul. After giving their consent to take part in the study Class I & II restorations of both upper and lower molars and premolars are performed.The treatment procedure is: The patients are offered local anesthetic before treatment start. The cavity is excavated and filled according to the guidelines for composite restorations.
The control procedure is:
The restoration is evaluated according to marginal adaptation, cavo surface marginal discoloration, approximal contact, fractures, caries associated with restorations and postoperative hypersensitivity. The controls will take place after two weeks, one year, two years and three years.
