Abstract Purpose To evaluate the accuracy of implant position using surgical guides fabricated by additive and subtractive techniques. Materials and Methods A partially edentulous standardized mandibular implant model with different bone densities and soft tissue was duplicated and a diagnostic wax‐up was performed for the #30 area. A reference radiographic guide was fabricated and cone beam computed tomography (CBCT) was made with the reference radiographic guide in place. A surgical...

Abstract Purpose To assess the effect of tooth preparation design on fracture resistance of zirconia‐reinforced lithium silicate overlays. Materials & Methods This study evaluated 50 human maxillary first molars with no caries, restorations or anatomical defects. The teeth were randomly divided into five groups (n = 10/group) based on preparation design for the fabrication of overlay restorations: (O) anatomical occlusal reduction, (OS) anatomical occlusal reduction with round...

Abstract Facial and intraoral scanners as well as additive manufacturing (AM) technologies can be integrated to virtually plan restorative procedures. The present article describes a digital workflow protocol for treatment planning an esthetic rehabilitation using direct composite restorations. The combination of facial digitalization and intraoral scans allowed a facially driven diagnostic waxing, while additive manufacturing technologies facilitate the translation of the digital waxing into the...

Abstract Purpose This study aimed to determine the most reliable scanning strategy and scanner type, using a new protocol for assessing the accuracy (trueness and precision) of intraoral scan data. Materials and Methods Five different maxillary and mandibular typodont pairs (n = 10) and 2 intraoral scanners were used for the study. A reference scan for each arch was obtained with an industrial scanner. Scanning strategies were classified into 2 continuous methods—continuous scan...

Abstract Acute lung injury (ALI) is a kind of lung serious disease which leads to the damage of alveolar epithelial cells and capillary endothelial. Lipopolysaccharide (LPS) is one of the common factors inducing ALI. The previous study has reported that the anti-inflammatory effect of peiminine, but little is known about its effect on the ALI induced by LPS. The aim of this study is to investigate the therapeutic effect of peiminine...

Objective: To determine the reliability and safety of posterior canal BPPV (pc-BPPV) treatment with subsequent assessment of the effectiveness of the maneuver in a single session, compared to the classic weekly procedure. Method: A prospective study of two randomized groups of unilateral pc-BPPV was performed: a weekly management group (27 patients) and single-session treatment group (26 patients). The number of maneuvers required to clear pc-BPPV, incidence of side effects (re-entries...

Hypothesis: The investigation aimed at measuring the relation between abutment length and Implant Stability Quotient (ISQ) for stability measurements on two types of bone-anchored hearing implant systems. Background: Measuring bone-anchored hearing implant stability using the ISQ has the inherent limitation that the measurement is dependent on the length of the abutment used on the implant. This dependency has not earlier been analyzed in depth. Therefore, ISQ measurements for different...

Objectives: To evaluate long-term stability and residual hearing preservation after cochlear implantation with electric acoustic stimulation (EAS). Study Design: Retrospective chart-analysis. Setting: University clinic. Methods: Long- and short-term hearing preservation (HP) of 18 EAS subjects (21 ears) was evaluated. Short-term was defined as follow-ups less than 12 months after surgery versus long-term outcomes longer than 12 months postsurgery. Results: ...

Objective: The incidence of sporadic vestibular schwannoma (VS) has increased significantly over recent decades. The rising incidence of VS has been largely attributed to the increasing use of magnetic resonance imaging (MRI), especially with regard to incidentally diagnosed tumors. However, no study to date has directly investigated this supposed etiology beyond the observation that VS incidence rates have risen in the post-MRI era. Therefore, the primary objective of the current study was...
