Statement of problem: Whether increasing the space for peri-implant soft tissues by using implant systems with conical or convergent transmucosal components would improve tissue stability and esthetics is unclear. Purpose: The purpose of this prospective clinical study was to evaluate the clinical and esthetic outcomes of using tissue-level...

Statement of problem Both direct and indirect techniques are used for dental restorations. Which technique should be preferred or whether they are equivalent with respect to bacterial adhesion is unclear. Purpose The purpose of this in vitro study was to determine the affinity of bacterial biofilm to dental restorative composite resins placed...

Purpose: To compare the qualitative and quantitative profile of Epstein-Barr virus (EBV) at external and internal implant surfaces between participants with peri-implantitis and healthy peri-implant tissues and to quantitatively assess the relation between EBV and periopathogens inside the microbiologic profile associated with peri-implantitis....

The placement of immediate implants in compromised sockets often requires adjunctive reconstructive measures. In particular, the loss of integrity of the buccal wall may preclude implant placement or, at least, it requires contextual, guided bone regeneration. There is no uniform consensus regarding the best biomaterial or strategy to...

An adequate volume of bone is one of the factors critical to successful osseointegration and long-term retention of endosseous dental implants. In situations where inadequate bone volumes exist, specially atrophic mandible, osseous ridge augmentation procedures often are necessary for predictable implant therapy. Grafts are fundamental for...

The design of the implant prosthesis–abutment complex appears crucial for shaping healthy and stable peri-implant soft tissues. The aim of the present animal study was to compare two implants with different healing abutment geometries: a concave design (TEST) and a straight one (CTRL). Transmission electron microscopy (TEM) was used to quantify...

The emerging literature has recently reported an alarming increase in peri-implantitis. This disease is typically described as the result of an imbalance between host response and bacterial load, supported by gram-negative anaerobic microflora. The current literature on the prevention and treatment of peri-implantitis does not allow for the...
