Increasing the Thickness of the Collagen Xenogeneic Matrix Prevents Early Matrix Degradation and Improves the Proliferation, Adhesion, and Viability of Human Gingival Fibroblasts and Mesenchymal Stem Cells.

Using autogenous grafts in mucogingival surgeries is related to postoperative morbidity and limited tissue availability, and thus xenogeneic matrices are increasingly used. This in vitro study evaluated the influence of xenogeneic collagen matrix thickness on cell adhesion, morphology, viability, proliferation, and matrix degradation. Matrices were divided into three groups: SLC: single layer of Lumina Coat, as commercially available (2-mm thickness); DLC: double layer of SLC (Lumina Coat); and MG: single layer of Mucograft, as commercially available (4-mm thickness).

A Simple Technique to Repair Feldspathic Porcelain Chipping in Screw-retained Implant-supported Prosthesis: A Clinical Technique.

Aim: This clinical technique report aimed to describe a composite resin repair technique performed in an implant-supported prosthesis.

Background: Veneering ceramic fracture or chipping is one of the most frequent clinical failures in dentistry. Therefore, the use of less time- and cost-consuming ceramic repair techniques is helpful in clinical practice.
