The relationship between occlusal overload and peri-implant bone loss remains a controversial topic in implant dentistry. A causal relationship between the incidence of marginal bone loss next to an implant and occlusal overload implies a treatment plan and occlusal scheme would benefit from a force management approach. A MEDLINE-assisted and hand search of peer-reviewed English literature and ...

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...

Discriminative learning when training and test data belong to different distributions is a challenging and complex task. Often times we have very few or no labeled data from the test or target distribution but may have plenty of labeled data from multiple related sources with different distributions. The difference in distributions may be both in marginal and conditional probabilities. Most of ...
