The purpose of this case series is to describe a restorative and surgical approach to treat the combined defect (CD)-gingival recession associated with noncarious cervical lesions (NCCL)-through connective tissue graft in combination with partial resin composite filling, restoring the crown zone plus 1 mm of the NCCL. A total of 10 patients were included. Bleeding on probing, probing depth, relative gingival recession, clinical attachment level, CD height, and dentin hypersensitivity were measured. The treatment provided statistically significant gain in clinical attachment level and shallow probing depths...

A preclinical trial was conducted to treat 54 mandibular critical-sized alveolar ridge defects in 27 canines. Each hemimandible was randomized to be treated with two different anorganic bovine bone grafts (group A = InterOss [SigmaGraft]; group B = Bio-Oss [Geistlich]) or negative control (group C = empty defect) followed by a 4-, 8-, or 12-week observation period. Microcomputed tomography, histology, histopathology, and histomorphometric analyses were performed to evaluate the safety and efficacy of these treatments...

Inaccuracy of computer-guided implant placement may lead to complications when combined with an immediately loaded prefabricated prosthesis. The aim of this case series was to describe the use of an intraoral welding technique to increase the predictability of immediately loaded implants supporting a fixed full-arch prosthesis after computer-guided flapless implant placement. A total of 60 Ankylos plus implants (Dentsply) with a width of 3.5 mm and a length of 8 to 14 mm were placed consecutively in 10 patients...

Early orthodontic tooth movement following regenerative surgery is controversial. In this case, during protraction of the maxillary right first premolar to substitute for the long-term missing maxillary right canine, Bio-Oss and Bio-Gide were used for lateral ridge augmentation at the area of the maxillary right lateral incisor and to cover the denuded surface at the buccal side of the first premolar. Orthodontic tooth movement (OTM) commenced 2 weeks after regenerative surgery. After 8 months, new bone formation was observed on the root surface of the first premolar during implant surgery...

Acellular dermal matrix allografts (ADMs) have been hypothesized to create a zone of immobile connective tissue (ICT) extending apical to the mucogingival junction (MGJ). This 12-month prospective randomized trial investigated the presence of ICT after the use of two commercially available ADMs with coronally advanced flaps in the treatment of Miller Class I and II recession defects. This study demonstrated that the use of either type of ADM resulted in predictable root coverage and a zone of ICT extending apical to the MGJ by 1...

Major and minor chipping of veneering porcelain are two of the most frequent complications in all-ceramic restorations with zirconia frameworks. In cases of major chipping, replacement of the affected restoration may be necessary. High-strength lithium disilicate ceramic offers new options to serve as veneering material in a sintering technique or as repair material for chipping in combination with the adhesive technique. The purpose of three case presentations here was to describe the use of lithium disilicate ceramic on zirconia frameworks for reliable and esthetic veneering in the posterior region and to repair extended chipping in conventional veneering materials...

This meta-analysis aims to compare the effect of the application of enamel matrix derivative (EMD) used alone with that of its use in combination with alloplastic materials in the treatment of periodontal intrabony defects. Relevant studies were retrieved from PubMed, the Cochrane Library, and Embase through November 2015. The main clinical outcomes were pocket probing depth (PPD) reduction, clinical attachment level (CAL) gain, gingival recession (REC) increase, and defect fill gain. Two separate meta-analyses were performed according to the length of follow-up...

The goal of this study was to histologically evaluate the healing process of subepithelial connective tissue graft in humans. A sample of 16 patients with Miller Class I or II localized gingival recession defects were consecutively treated with a bilaminar technique. At baseline and after 2 months, tissue samples were taken from the donor and recipient sites. The revascularization and reinnervation of the graft were examined by means of hematoxylin-eosin and immunohistochemical techniques. After 2 months of healing, the integration of the grafted tissue was evident with the connective tissue expressing features belonging to both the recipient (cellular component) and the donor site (extracellular matrix) in the inner and superficial layers, respectively...

Treatments for enhancing surface energy were studied in an effort to create a more favorable environment for cell adhesion. Cold argon plasma (CAP) is able to improve titanium-cell contact, producing hydrophilic surfaces with higher wettability. The aim of this in vitro study was to estimate the early cell morphology after CAP treatment of different commercially available titanium surfaces. Surface wettability was significantly augmented in all the treated samples. The authors investigated how CAP affected the behavior of osteoblasts by evaluating the cell morphology outcome...

Periodontal biotype is a key element influencing esthetic treatment outcomes in clinical practice. However, while the soft and hard tissue thicknesses of maxillary anterior teeth have been widely studied, information regarding mandibular anterior teeth is scarce. Therefore, the aim of this study was to determine whether there is a relationship in terms of hard and soft tissue thickness between maxillary and mandibular anterior teeth. The present study included 90 maxillary and 90 mandibular anterior teeth in 15 healthy patients...

Using simultaneous transplantation of bone graft materials, this study examined the long-term outcomes of a ridge augmentation technique applied to deficient labial alveolar bone plate in the esthetic zone. Results were based on a case series in which study cases (n = 10) were divided into two groups. Group 1 exhibited intact labial alveolar bone, while group 2 alveolar bone was dehiscent at the labial aspect. The clinical outcome was longitudinally monitored using cone beam computed tomography 4 to 7 years after the procedure...

This study evaluated the microhardness of two resin cements and a low-viscosity resin composite when light-cured under different ceramic thicknesses. A total of 20 samples (10.0 × 1.0 mm) of each material were polymerized by means of a LED light source with an intensity of 1,100 mW/cm(2) for 20 seconds. For each experimental group, different ceramic thicknesses (0.5 mm, 1.0 mm, and 1.5 mm) were applied to each sample. For the control group, the samples were polymerized without the presence of ceramics. Each material was then stored in dry vials that inhibited the passage of light for a period of 24 hours...

The aim of this study was to analyze changes in pink and white esthetics in the anterior zone through evaluation of an immediately placed zirconia implant using the Pink and White Esthetic Scores (PES and WES) in 20 patients. Two clinical photographs were compared: one taken directly after placement of the permanent crown (mean PES = 12.8; mean WES = 8.5) and the other taken at a later time (mean PES = 12.8; mean WES = 8.6; not significant). Volunteers found it difficult to correctly identify the implant. Patients completed a questionnaire regarding the pink and white implant esthetics...

The aim of this study was to present the use of retroauricular full-thickness skin grafts in vestibuloplasty surgeries for dental implant rehabilitation in vascularized fibula grafts. Two patients underwent mandibular reconstruction with vascularized fibula grafts due to mandibular gunshot injuries. Inadequate sulcus gaps secondary to mandibular soft tissue deficiencies were managed by full-thickness autologous skin grafts harvested from the retroauricular region. Dental rehabilitation was achieved by implants placed in free fibula grafts...

The aim of this retrospective study was to compare clinical and radiographic outcomes of the interpositional (inlay) augmentation technique in atrophic posterior partially edentulous mandibles using three different types of block bone grafts: autogenous bone block harvested from the iliac crest, deproteinized bovine bone mineral block, and collagenated equine bone block. A total of 115 patients were included with a 4.2-year mean after-loading follow-up. Data seem to suggest that heterologous bone blocks are similar in results to autogenous bone blocks, so they might be considered preferable as they avoid invasive harvesting surgeries...
