Current status of zirconia-based all-ceramic restorations fabricated by the digital veneering technique: a comprehensive review.

Objectives: Delamination and chipping are major complications of veneering material on zirconia-based all-ceramic restorations. The digital veneering technique was introduced to overcome these complications as both zirconia frameworks and veneering ceramic are fabricated by computer-aided design/computer-aided manufacturing (CAD/CAM). The aim of this review is to report all articles that evaluate zirconia-based all-ceramic restorations fabricated by the digital veneering technique.

Clinical procedures, designs, and survival rates of all-ceramic resin-bonded fixed dental prostheses in the anterior region: A systematic review.

Objectives: The aim of this study is to systematically review all the clinical articles about all-ceramic resin-bonded fixed dental prosthesis (RBFDP) in the anterior region and assess their designs, clinical procedures, and survival rates. A systematic review was conducted after searching electronic databases PubMed/Medline and EBSCOhost Research Databases for articles published in English between 1987 and July 2017.

Materials And Methods: The inclusion criteria were selected as all clinical studies, original design clinical reports, and clinical reports (follow-up time more than 1 year) as all clinical information in the literature are desired to be included in the present review.

An earplug technique to reduce the gag reflex during dental procedures.

Background: The gag reflex is a frequent problem occurring during dental treatment procedures, especially while making impressions of the maxillary teeth. The present study aims to evaluate the efficacy of a simple earplug as an external auditory canal stimulator to supress the profound gag reflex and as a second step, to map areas of the oropharynx suppressed by this technique.

Methods: In the first step of the study, 90 patients who had a gag reflex during the impression procedure were allocated to a study group, a sham group, and a control group for evaluating the efficacy of the earplug technique.

Scintigraphic, histologic, and histomorphometric analyses of bovine bone mineral and autogenous bone mixture in sinus floor augmentation: a randomized controlled trial--results after 4 months of healing.

Purpose: To test our null hypothesis stating that the mixture of autogenous cortical bone scrapings and bovine bone mineral (BBM) in a ratio of 1:4, compared with BBM alone, would have no significant effect on new bone formation 4 months after maxillary sinus floor augmentation.

Patients And Methods: Twenty-four patients presenting with alveolar bone height of less than 5 mm in the narrowest zone between the sinus floor and alveolar crest were randomly assigned to 2 treatment groups in this randomized controlled trial. We augmented 12 maxillary sinuses with a mixture of BBM and cortical autogenous bone graft, which was collected from the lateral wall of the maxillary sinus by a bone scraper, and 12 maxillary sinuses with BBM alone.

Decontamination of autogenous bone grafts collected during dental implant site preparation: a pilot study.

Dental implant site preparation produces bone particles that can be used as autogenous bone graft material for the reconstruction of alveolar bone defects; however, collected bone particles are contaminated with oral microorganisms that may cause augmentation failure due to complications associated with infection. The stringent aspiration protocol, preoperative oral chlorhexidine rinsing, and antibiotic prophylaxis were implemented before collecting bone particles. Nonetheless, collected bone particles were still contaminated with bacteria, and, therefore, decontamination of the collected bone particles with chlorhexidine or clindamycin was considered.

Decontamination of autogenous bone grafts collected from dental implant sites via osteotomy: a review.

Autogenous bone particles can be obtained with bone collectors during implant osteotomy; however, collected bone particles contain oral microorganisms that may cause infectious complications. The purpose of this review was to summarize the clinical studies that have evaluated the degree of this contamination and the effectiveness of different decontamination methods. Stringent aspiration protocol, preoperative oral chlorhexidine rinse, and antibiotic prophylaxis are important precautions to be implemented when collected bone particles are to be implanted.

Required minimum primary stability and torque values for immediate loading of mini dental implants: an experimental study in nonviable bovine femoral bone.

Immediate loading of implants decreases the period a patient has to remain edentulous. However, for successful immediate loading in clinical practice, a strong initial fixation with bone is a prerequisite. In the present study, it is aimed to measure the primary stability, minimum placement, and removal torque values of mini dental implants which were originally designed for immediate loading.

A mini dental implant-supported obturator application in a patient with partial maxillectomy due to tumor: case report.

Following a partial maxillectomy in a patient, the oral and nasal cavities remain open, providing a passageway for transmission of air and fluids between the 2 cavities. In such cases the primary aim should be the construction of an implant-supported obturator prosthesis with adequate retention, stability, and peripheral seal. In this case report, a 34-year-old female patient who underwent a class II (according to Okay et al.

Treatment of a narrow, single tooth edentulous area with mini-dental implants: a clinical report.

The narrowing of an extraction site often becomes problematic when attempting to restore the space with a conventional wide-diameter implant. A woman is presented who was treated with a square head, mini-dental implant-supported fixed denture for a maxillary with a narrowed edentulous area, with a mesiodistal width of 5 mm. The implant, with a diameter of 2.
