يعد تجميل الأسنان أحد أهم الاجراءات الحديثة التي تحدث اثارا نفسية إيجابية تحسن من الصورة الذاتية للمريض وتمثل بعداً جديداً للمعالجة السنية
These days compositedefinitly became at the top of direct cosmetic restorations, and the most using restorative material, due to this development now it's used for direct Veneers &Lumineers. Because of the high sensitivity of its application, gene ral practitioner should achieve a dry, clear work field, especially gingival area. The aim of the study was to use the modified metal matrix, which used in this study, is to retract the gum, isolate the tooth from the exudation of the sulcus and bleeding gum avoiding margin leakage, also provide acceptable continuance between the restoration surface and the under gum tooth structure, to prevent forming reverse stage under gum. 120 teeth were included in this study, all teeth were treated using the modified metal matrix, 10 teeth at least for each patient, with no orthodontic treatment. The results have practically proved getting all goals; retracted gum, tooth isolated from exudation of the sulcus and bleeding gum, also provided continuance between veneers and under gum tooth structure, and not having reverse stage which is the main cause of gum inflammation, beside time saving and easy direct veneer application.
Porcelain Laminate Veneers have shown promising results recently when used as an alternative to metal ceramic restorations for the anterior teeth. Long-term success for any restoration depends on the marginal fit, because marginal gaps increase pl aque accumulation and causing periodontitis. The aim of this study was to Asses marginal fit changes according to were curing the bond agent before or after cementation.
Interdental Papilla deficiency may occur due to many factors such as traumatic oral hygiene procedure, plaque associated lesions and diverging roots following orthodontic treatment. Many of invasive and non-invasive techniques have been suggested to reconstruct the deficient interdental papilla. Treatment using hyaluronic acid gel injection is the most recent non-invasive technique which characterized by its easily application as well as avoidance exposing the patient to surgical procedures. The purpose of this study was to evaluate the efficiency of repeated cross-linked hyaluronic acid gel injection in management of deficient interdental papilla at the esthetic zone after six months of treatment.
This study aimed to test the efficiency of debonding porcelain laminate veneers (PLV) by using two application modes of Er:YAG laser (contact and non-contact mode), and testing the change in dental pulp temperature for both application modes. Sixt een extracted, non-carious human maxillary premolars, prepared for receiving PLV, which fabricated of e.max and bonded by light cured resin cement. They divided into two groups, each of them had 8 samples based on the application mode; group A with noncontact mode, and group B with contact mode. Veneers of both groups debonded by the same laser parameters (360mJ, 15Hz) during loading of a 20newton force on a specially fabricated cervical margin of veneers. Debonding time and change of temperature was recorded, then entered into SPSS V.19 and T-test for independent samples was applied. All veneers were debonded, samples of non-contact mode group had much lower debonding time (12.6 second) than contact mode samples (96.3 second), but with higher change of temperature in non-contact (4.2 centigrade) than in contact mode (2.9 centigrade).p value was much less than 0.05%. Within limits of this study, we can conclude that non-contact application mode was more efficient in reducing debonding time than contact application mode at same laser energy and frequency parameters, but with a higher change in pulp temperature.
