A Novel Technique for Preparation of Recipient Site and Autologous Bone Grafting in Autotransplantation of Single-Rooted Teeth: A Report of Two Cases.

Low-speed drilling without irrigation has a long history of use in implant dentistry. It provides the advantage of avoiding the wash-out of proteins and biomolecules from the bone. In this case report, we describe the novel use of this drilling protocol in the preparation of bone alveolus during the procedure of tooth autotransplantation.

Oral Lichen Planus Treated With Plasma Rich in Growth Factors.

Frequency of Technical Complications in Fixed Implant Prosthesis: The Effect of Prosthesis Screw Emergence Correction by Computer-Aided Design/Computer-Aided Manufacturing.

Computer-aided design/computer-aided manufacturing (CAD-CAM) technology permits the angular correction of screw emergence into the prosthesis; however, there is lack of controlled clinical studies that assess the frequency of technical complications in angled screw channel restorations. This controlled clinical study was designed to assess technical incidences in angled screw channel restorations. Patients who underwent placement of implant prosthesis between November 2014 and December 2015 were screened.

Background: Local deficit of several biomolecules have been described in oral lichen planus (OLP). Such a deficit impairs cellular functions and cell-matrix communication.

Purpose: Assess the efficacy of the local application of autologous biomolecules in the treatment of erosive OLP.

Early marginal bone stability of dental implants placed in a transalveolarly augmented maxillary sinus: a controlled retrospective study of surface modification with calcium ions.

Background: Recently, components of the extracellular cellular matrix have been assessed to enhance the biological response to dental implants. This study aims to assess the effect of surface modification with calcium ions on the early marginal bone loss of dental implants placed in a transalveolarly augmented maxillary sinus.

Methods: A retrospective study of transalveolar sinus floor augmentation was conducted in a single private dental clinic.

Prognosis of Dental Implants Immediately Placed in Sockets Affected by Peri-implantitis: A Retrospective Pilot Study.

The aim of this study was to describe a protocol and analyze the outcomes of immediate replacement of failed implants due to peri-implantitis. A total of 17 patients (mean age: 58 ± 10 years) had 22 failed implants that were immediately replaced. One implant failed 16 months after insertion, resulting in an implant survival rate of 94.

Unusual Presentation of Castleman Disease in the Oral Cavity.

Castleman disease (CD) is a benign lymphoproliferative disease of unknown aetiology that rarely occurs in the head and neck region. Herein, the authors describe a patient of intraoral CD and its management. A 55-year-old female patient attended our clinic because of a 1-year history of a mass in the posterior hard palate region.

Long-Term Outcomes of Immediate Implant Placement Into Infected Sockets in Association With Immediate Loading: A Retrospective Cohort Study.

Background: There is a paucity of studies examining long-term outcomes of immediate loading of dental implants immediately placed into infected sites. This study aims to evaluate long-term outcomes of immediate loading of postextraction implants placed in infected sites.

Methods: Patients were selected if they had postextraction implants in the anterior maxilla that were inserted in the period from December 2006 to June 2015 and immediately loaded.

Rehabilitation of Atrophied Low-Density Posterior Maxilla by Implant-Supported Prosthesis.

The rehabilitation of edentulous posterior maxilla is a challenging task that could be complicated by the availability of low-density and reduced height of alveolar bone. Patients were enrolled in this study upon the presence of type IV bone and residual bone height <5 mm in posterior maxilla. Novel procedure for transalveolar sinus floor elevation was described to insert 10 short implants in 4 patients.

Effects of calcium ions on titanium surfaces for bone regeneration.

The chemistry and topography of implant surfaces are of paramount importance for the successful tissue integration of load-bearing dental and orthopedic implants. Here we evaluate in vitro and in vivo titanium implant surfaces modified with calcium ions (Ca(2+) surfaces). Calcium ions produce a durable chemical and nano-topographical modification of the titanium oxide interface.

Nontraumatic Implant Explantation: A Biomechanical and Biological Analysis in Sheep Tibia.

Preclinical research in a sheep tibia model has been conducted to evaluate the underlying mechanisms of the nontraumatic implant explantation of failed implants, which allow placing a new one in the bone bed. Twelve dental implants were placed in sheep diaphysis tibia and once osseointegrated they were explanted using a nontraumatic implant explantation approach. Implant osseointegration and explantation were monitored by means of frequency resonance, removal torque, and angle of rotation measurement.
