Different Esthetic Assessment of Anterior Restorations by Patient and Expert: A Prospective Clinical Study.

Background: Esthetically pleasing, bright teeth and a symmetrical dental arch are of great importance. There are only a few scientific studies that compare the evaluation of anterior restorations by experts and patients. Additionally, there are hardly any studies that deal with the weighting of esthetic parameters.

Effect of Liquid Blood Concentrates on Cell Proliferation and Cell Cycle- and Apoptosis-Related Gene Expressions in Nonmelanoma Skin Cancer Cells: A Comparative In Vitro Study.

Nonmelanoma skin cancer (NMSC) presents a significant challenge to global healthcare due to its rising incidence, prompting the search for innovative treatments to overcome the limitations of current therapies. Our study aims to explore the potential effects of the liquid blood concentrate platelet-rich fibrin (PRF) on basal cell carcinoma cells (BCCs) and squamous cell carcinoma cells (SCCs) in order to obtain results that may lead to new possible adjunctive therapies for managing localized skin cancers, particularly NMSC. Basal cell carcinoma (BCC) cells and squamous cell carcinoma (SCC) cells were indirectly treated with PRF generated via different relative centrifugation forces, namely high and low RCF PRF, for 7 days.

Comparative Accuracy of Stationary and Smartphone-Based Photogrammetry in Oral and Maxillofacial Surgery: A Clinical Study.

Three-dimensional facial scan technologies, such as stereophotogrammetry, are frequently used in oral and maxillofacial surgery, dentistry, and plastic surgery to assess patient outcomes and plan surgical procedures. Most facial scanners rely on stationary clinical systems, which provide high accuracy and reliability in generating 3D representations of the human face; however, they are cost-intensive and immobile. Recently, smartphone-based facial scan applications that use stereophotogrammetry have been developed.

Long-Term Survival in Grafted Sites of Dental Implants.

Objective: Vertical and horizontal bone insufficiency in both the maxilla and mandible has long been a contraindication for implants. This review provides an overview of the long-term survival rates of implants in augmented alveolar bone after the guided bone regeneration (GBR) technique.

Results: GBR in a combination of allogeneic or xenogeneic graft material with a barrier membrane and simultaneous or delayed placement of dental implants has proven to be a very effective and feasible treatment option in long-term studies up to 35 years.

Horizontal Guided Bone Regeneration of the Posterior Mandible to Allow Implant Placement: 1-Year Prospective Study Results.

Objective: Assess whether horizontal ridge augmentation with guided bone regeneration (GBR) using deproteinized bovine bone mineral (DBBM), autologous bone, and a resorbable collagen membrane supports successful implant placement.

Materials And Methods: This open, prospective, single-cohort, multicenter clinical study included patients with ridge defects that required GBR prior to implant insertion. The primary endpoint was radiologically assessed bone gain after 8 months post-GBR, measured at the center of planned implant sites.
