Comparison of the Effect of Implant Abutment Surface Modifications on the Retention of Implant-Supported Restorations.

Purpose: To evaluate and compare the difference in retention between implant-supported restorations with and without surface modification of the implant abutments.

Materials And Methods: A total of 30 patients with singletooth implants were restored with cement-retained (Multilink N, Ivoclar) restorations using titanium base abutments (Variobase, Straumann) and randomly assigned surface modifications. Group 1 used nonmodified abutments, group 2 used sandblasted abutments, and group 3 used sandblasted abutments followed by an application of metal primer.

Assessment of angiogenic potential of mesenchymal stem cells derived conditioned medium from various oral sources.

Background: Abnormal angiogenesis hamper blood vessel proliferation implicated in various biological processes. The current method available to clinically treat patients to enhance angiogenesis is administering the angiogenic growth factors. However, due to a lack of spatiotemporal control over the substantial release of these factors, numerous drawbacks are faced such as leaky vasculature.

Anatomic variations of the osteomeatal complex and its relationship to patency of the maxillary ostium: A retrospective evaluation of cone-beam computed tomography and its implications for sinus augmentation.

Aim: The aim of this study is to determine the incidence of obliterated osteomeatal complex (OMC) due to the presence of anatomic variants.

Settings And Design: Retrospective Study.

Materials And Methods: In this retrospective study, a total of 71 patients, 34 males and 37 females, aged 35-65 years were included in the study.

Comparative analysis of transmittance for different types of commercially available zirconia and lithium disilicate materials.

Purpose: Translucency and colour stability are two most important aspects for an aesthetic dental restoration. Glass ceramic restorations are popular amongst clinicians because of their superior aesthetic properties. In the last decade, zirconia has generated tremendous interest due to its favorable mechanical and biological properties.
