Aim: The purpose of the study was to assess the marginal adaptation and discrepancy of SSC's. Differences in adaptation and discrepancy between the four surfaces (mesial, lingual, distal, and buccal) were evaluated. Methods: The placement of stainless steel crowns were completed on a phantom head in accordance with the clinical technique. The ideal tooth preparation was made and this 'master to...

background and aims: in various clinical situations, mineral trioxide aggregate (mta) may come into direct contact with blood. the aim of the present study was to evaluate the effect of exposure to blood on marginal adaptation and surface microstructure of mta. materials and methods: thirty extracted human single-rooted teeth were used in this study. standard root canal treatment was carried ou...

STATEMENT OF PROBLEM Three main factors which determine the success of an All-ceramic restoration are esthetic value, resistance to fracture and third being the marginal fit. Marginal fit and internal adaptation are crucial factors in increasing the longevity of the restoration. Newer and economical CAD CAM systems have been introduced claiming better marginal fit and adaptation of All ceramic ...

Kron harabiyeti fazla olan kök -kanal tedavili molar dişlerin restorasyonunda, direkt ve indirekt restorasyonlar dahil olmak üzere farklı konvansiyonel tedavi seçenekleri bulunmaktadır. Endokronlar, intraradiküler post, kor kronu tek bir parçada birleştiren monoblok yapıda olan, geleneksel post -kor restorasyonlara alternatif olarak ortaya çıkmış güncel seçeneğidir. Marjinal internal uyum, prot...

PURPOSE To evaluate the clinical performance of inlays and onlays luted with two different resin cements, mixed at different temperatures and to evaluate the marginal adaptation of the restorations. MATERIALS AND METHODS One hundred IPS e.max restorations (82 onlays, 18 inlays; 84 molars, 16 premolars) were placed in 50 patients (28 females, 22 males, mean age, 33 years). The restorations wer...

Introduction – Shrinkage during polymerization of resin-based composite materials may lead to gap formation and hamper the marginal adaptation of the restorations. To reduce the problem of polymerization shrinkage, a new composite material (FiltekTM Silorane, 3M-ESPE, Germany), with a reduced shrinkage, has been marketed. Objective – To investigate whether reduced polymerization shrinkage impro...

PURPOSE The objective of this study was to clinically evaluate sealed composite restorations after 10 years and compare their behavior with respect to controls. METHODS AND MATERIALS The cohort consisted of 20 patients aged 18 to 80 years with 80 composite restorations. All participants in the sealing and no-treatment groups presented with clinical features for the marginal adaptation that de...
