The effect of antiresorptive therapy on the prevalence and severity of oral lichen planus: a retrospective study.

Background: Antiresorptive therapy (AR) disrupts osseous homeostasis and can induce direct irritation over the gastrointestinal mucosa; however, its possible erosive effects on the oral epithelium have not been totally described. Among the most frequent oral erosive lesions, oral lichen planus (OLP) frequently presents as painful mucosal ulcerations, arising from basal membrane inflammatory damage. Thus, the aim of this retrospective study was to describe the association between AR and the incidence of OLP.

Serine enrichment in tumors promotes regulatory T cell accumulation through sphinganine-mediated regulation of c-Fos.

CD4 regulatory T (T) cells accumulate in the tumor microenvironment (TME) and suppress the immune system. Whether and how metabolite availability in the TME influences T cell differentiation is not understood. Here, we measured 630 metabolites in the TME and found that serine and palmitic acid, substrates required for the synthesis of sphingolipids, were enriched.

Long-Term Peri-Implant Health and Papilla Formation at Healed Sites by Chairside Provisionalization of Single-Tooth Implants: A Prospective Case Series.

Purpose: Several procedures are performed to achieve optimal esthetic results in single-tooth implants. However, there is discordance regarding the potential benefit and risks of immediate implant loading/provisionalization. The aim of this prospective case series is to investigate the effect of immediate provisionalization of single-tooth implants at healed sites for periimplant soft-tissue conditions, focusing on papilla formation around single implants.

Etiology, pathogenesis and treatment of peri-implantitis: A European perspective.

Peri-implantitis is a plaque-associated pathological condition occurring in tissues around dental implants. It is characterized by inflammation in the peri-implant mucosa and progressive loss of supporting bone. Over the last 30 years, peri-implantitis has become a major disease burden in dentistry.

Current Concepts for the Treatment of Peri-implant Disease.

Peri-implant diseases are defined as bacterial plaque-induced inflammatory conditions affecting implant-surrounding tissues and are classified as peri-implant mucositis and peri-implantitis. Peri-implant mucositis is characterized by an inflammatory lesion that resides in the soft tissue compartment, whereas at peri-implantitis sites the lesions also feature progressive loss of implant-supporting bone. Inflammation resolution and disease progression arrestment are the main therapeutic endpoints of the treatment of peri-implant diseases.

Selecting biomaterials in the reconstructive therapy of peri-implantitis.

Peri-implantitis is a pathogenic inflammatory condition characterized by progressive bone loss and clinical inflammation that may compromise the stability of dental implants. Therapeutic modalities have been advocated to arrest the disorder and to establish peri-implant health. Reconstructive therapy is indicated for bone defects exhibiting contained/angular components.

Clinical and Radiographic Outcomes of Resective Surgery with Adjunctive Implantoplasty Over a 6- to 11-Year Follow-up: A Case Series.

Diverse surgical approaches, such as resective, reconstructive, and combined therapy, have been proposed for peri-implantitis treatment. A resective surgical approach with an adjunctive modified implantoplasty refers to the modification of the implant body into a constricted area to mimic a 'waist' silhouette. This modified technique forms an adequate concave smooth area that may favor the outcomes of resective surgical therapy for soft tissue adaptation, biofilm control, and possible peri-implant bone gain over the long term.

Clinical efficacy of guided bone regeneration in peri-implantitis defects. A network meta-analysis.

Guided bone regeneration (GBR) at peri-implantitis-related bone defects involves the placement of bone-filler particles in the intrabony defects and the application of a barrier membrane. The efficacy of different GBR-supported reconstructive measures as well as their potential superiority compared to non-GBR-supported treatment strategies for bone defects at peri-implantitis sites, however, remains unclear. Therefore, this analysis was designed to evaluate the long-term (≥12 months) clinical efficacy of GBR-supported reconstructive surgical therapy for peri-implantitis-related bone defects.

Objectives: To test whether soft tissue volume augmentation using a collagen matrix (VCMX) leads to noninferior results in terms of gain of mucosal thickness at single implant sites, compared to connective tissue grafts (SCTG).

Methods: The study was designed as a multi-center randomized controlled clinical trial. Subjects in need of soft tissue volume augmentation at single tooth implant sites were consecutively recruited at nine centers.

Three-dimensional changes of a porcine collagen matrix and free gingival grafts for soft tissue augmentation to increase the width of keratinized tissue around dental implants: a randomized controlled clinical study.

Background: Emerging clinical data points to the relevance of the presence of keratinized tissue (KT). Although apically positioned flap/vestibuloplasty along with free gingival graft (FGG) is considered as a standard intervention for augmenting KT, substitute materials appear to be a viable treatment alternative. So far, there is a lack of data investigating the dimensional changes at implant sites treated with soft-tissue substitutes or FGG.
