Student Theses, Dissertations and Capstones
Introduction: One factor that contributes greatly to the lower face appearance and orthodontists have the ability to affect is lip profile. Clinical assessment of the lip profile is an important element in the decision of orthodontic treatment planning and in the evaluation of treatment progress and outcome. Three known factors influence the lip profile; the lip thickness, the underlying bone, and the tooth position. The positions and inclinations of the anterior teeth can affect the lip position, but it is unclear whether orthodontic brackets bonded to the labial surface of anterior teeth move the lip position and thereafter change the …
Influence Of Immediate Dentin Sealing On The Bond Strength Of Indirect Bonded Restorations, Alexander Duque
Influence Of Immediate Dentin Sealing On The Bond Strength Of Indirect Bonded Restorations, Alexander Duque
Student Theses, Dissertations and Capstones
Introduction: A critical issue and concern that has been documented in dentistry is the complexity of bonding to dentin, a fact that has been referred to as a less reliable technique due to the intrinsic characteristics of the dentin substrate. Effectiveness on dentin bonding is a clinical important approach for indirect bonded restorations in order to achieve a good adhesion that can surpass the test of time. Long-term clinical trials have shown that indirect bonded restorations have an increased risk of failure when using dentin as the major substrate. Consequently, an effort should be made to improve techniques and materials …
