Objective: To describe the clinical use of nitride-coated titanium CAD/CAM implant abutments in the maxillary esthetic zone in two patients with high esthetic and functional demands and, to highlight the advantages of nitride-coated milled titanium abutments when compared to stock/custom titanium, one-piece monolithic zirconia, and hybrid metal-zirconia implant abutments.
Clinical Considerations: Due to the inherent mechanical and esthetic clinical challenges, single implant-supported reconstructions in the maxillary esthetic zone are a complex restorative treatment. While CAD/CAM technology has been suggested to enhance and ease implant abutment design and manufacturing, implant abutment material selection remains as a critical decision affecting restoration's long-term clinical outcomes.
A total 302 teeth (148 molars and 154 premolars) corresponding to 152 patients aged ≥18 years were evaluated for caries using the ICDAS (International Caries Detection and Assessment System), fluorescence (DD, DIAGNOdent) and electrical impedance (IMS, CarieScan PRO) systems. Fissurotomy and intraoral radiographs were used as the gold standard. Accordingly, 27.

Background: Nonsurgical treatment, resective surgery, reconstructive surgery, or combined approaches have been proposed for the treatment of peri-implantitis, with variable results.
Purpose: To evaluate the 1-year clinical and radiographic outcomes following combined resective and reconstructive surgical treatment with topical piperacillin/tazobactam antibiotic in the management of peri-implantitis.
Material And Methods: Forty-three patients diagnosed with peri-implantitis were included.
Aim: Periodontal treatment is reported to be associated with an improved periodontal condition in diabetic patients. Therefore, a comprehensive review of meta-analyses was conducted to evaluate whether periodontal treatment can improve glycemic control in patients with type 2 diabetes.
Materials And Methods: The search on electronic databases included PubMed-Medline, Cochrane Library, Scopus, and LILACS databases.
Purpose: To evaluate orthodontic treatment outcome in patients treated with a lingual appliance (Incognito™ Appliance System, 3M Unitek, Monrovia, CA, USA) versus patients treated with a labial appliance (Victory series™, 3M Unitek, Monrovia, CA, USA).
Methods: A total of 72 patients were retrospectively analyzed. The complexity of each case was evaluated using the American Board of Orthodontics (ABO) Discrepancy Index (DI), and orthodontic clinical outcomes were evaluated using the ABO Objective Grading System (cast-radiograph evaluation: C‑R Eval).
Objective: A systematic review and meta-analysis was thus conducted to answer the following focused question based on PICO strategy: Is there any 3D matrix biomaterial used for root coverage of human Miller class I and II defects equivalent with the connective tissue graft in localized defects of at least 2 mm and 3 mm?
Material And Methods: The search on electronic database included MEDLINE, Cochrane Central Register of Controlled Trials, Clinical Trials.gov, Web of Science, and New Zealand/Australian Clinical Trials. Only randomized clinical trials (RCTs) that compared connective tissue graft (CTG) with at least one 3D matrix alone for root coverage in Class I and II Miller localized defects of at least 2 mm, with at least 6 months follow-up, were included in this systematic review.
Background: A number of reference patterns such as the interincisal line, curve of the upper lip, width of the smile or shape of the teeth have been studied in different populations. Determining the frequency of different smile aesthetic parameters in a European Caucasian population and exploring possible gender differences is important in order to obtain predictable treatment outcomes.
Methods: Photographs were obtained under resting and forced smiling conditions in 140 individuals (70 males and 70 females) with a mean age of 20.
The objective of this study was to evaluate the clinical ability of Near-Infrared Light-Transillumination (NILT) for approximal dentinal caries detection and to compare with direct digital-radiography (DDR), as well as to determine whether the combination of both techniques improves the diagnostic capacity of the lesions. From 88 patients (over 18 years), 138 posterior teeth (76 molars and 62 premolars), that had approximal caries reached into dentine determined by DDR, were included. Lesion extension and DDR images were scored as follows: D0 = sound surface, D1/D2 = caries restricted to the outer/inner-half of the enamel, and D3/4 = caries restricted to the outer/inner-half of the dentin.

Methods: We conducted a retrospective study of 72 patients. The Peer Assessment Rating (PAR) index was measured at the start (T0) and end (T1) of treatment.
Dental esthetics need to be defined from the scientific perspective in order to obtain predictable treatment outcomes and avoid the effects of subjectivisms on the part of the dental profesional. It can be deduced that the ideal dimensions in the maxillary anterior sector are difficult to establish. Therefore, the primary purpose of this study was to define the dimensions of the maxillary anterior teeth and the relationships between them.

The null hypothesis was that both surgical procedures elicit a similar immune response of the peri-implant soft tissues.
Design: Thirty-one healthy patients were included in this study, in which two implants were placed in the right and left maxillary pre-molar regions.
Background: An evaluation is made of possible differences in treatment effects between labial and lingual fixed appliances.
Methods: A comprehensive search was made of the PubMed-Medline, Cochrane Library and LILACS databases, with an additional manual search covering the period up until April 2017. There were no restrictions in terms of year of publication or language.

Objective: To compare the clinical and histologic outcomes of two different grafting materials (allograft and xenograft) when combined with autogenous bone and covered with a collagen membrane for sinus augmentation.
Material And Methods: A parallel case series of fourteen patients in need of a unilateral sinus augmentation was evaluated in this study. Seven patients received a graft composed by autologous cortical bone (ACB) and anorganic bovine bone in a ratio of 1:1; the other seven patients received ACB mixed with an allograft in the same ratio.
Background: When considering dental implant rehabilitation in atrophic posterior sectors, the maxillary sinuses must be evaluated in detail. Knowledge of the anatomical variations and of the potential lesions found in these structures conditions the outcome of sinus lift procedures and therefore of the dental implants. A systematic review is made to determine the frequency of anatomical variations and pathological findings in maxillary sinuses among patients subjected to cone beam computed tomography (CBCT).
