Intra-sinus rigid fixation of a resorbable barrier membrane to repair a large perforation of the sinus membrane: a technical note.

A resorbable barrier membrane is commonly used for the repair of perforated sinus membranes during sinus lifting surgeries. However, repairing largescale perforations poses challenges for clinicians as the protection and isolation of graft material remain uncertain. With this technique, we aimed to prevent graft material loss and subsequent sinus-related complications using intra-sinus rigid fixation of the resorbable barrier membrane in cases with a large perforation of the sinus membrane.

Radiologic comparative analysis between saline and platelet-rich fibrin filling after hydraulic transcrestal sinus lifting without adjunctive bone graft: A randomized controlled trial.

Objectives: To evaluate implant survival rate, any complications, and changes in residual alveolar bone height (RABH) using saline or platelet-rich fibrin (PRF) filling after hydraulic transcrestal sinus lifting.

Methods: Dental implants were placed after hydraulic transcrestal sinus lifting and the filling of saline (20 patients) or PRF (20 patients). Outcome measurements were implant survival, any complications, and RABH changes.

Hydraulic Transcrestal Sinus Lift: Different Patterns of Elevation in Pig Sinuses.

Purpose: The aim of this study was to evaluate different patterns of sinus membrane elevation in pig jaws.

Materials And Methods: A total of 30 pig jaws (60 sinuses) were used for the present investigation. The hydraulic Crestal Approach Sinus kit was used to elevate sinus membrane, and different elevation patterns were recorded.

The role of tactile sensation in online and offline hierarchical control of multi-finger force synergy.

The hand, one of the most versatile but mechanically redundant parts of the human body, must overcome imperfect motor commands and inherent noise in both the sensory and motor systems in order to produce desired motor actions. For example, it is nearly impossible to produce a perfectly consistent note during a single violin stroke or to produce the exact same note over multiple strokes, which we denote online and offline control, respectively. To overcome these challenges, the central nervous system synergistically integrates multiple sensory modalities and coordinates multiple motor effectors.

Assessment of dentists' subjective satisfaction with a newly developed device for maxillary sinus membrane elevation by the crestal approach.

Purpose: The purposes of this study were to assess the dentists' subjective satisfaction with the crestal approach sinus (CAS) kit, a device for maxillary sinus membrane elevation by the crestal approach using a special drilling system and hydraulic pressure, and to summarize the subjective satisfaction of dental implants placed after a sinus lift procedure with the CAS kit.

Methods: Thirty dental clinicians who had experience with dental implant placement after a sinus lift procedure with the CAS kit from June 2010 to May 2012 were included in this study. The questionnaire for the evaluation of the dentists' subjective satisfaction with the CAS kit was sent to the respondents and returned.

A multicenter prospective study in type IV bone of a single type of implant.

Purpose: To analyze the success and survival rates of the Osstem GSII (Osstem, Busan, Korea) implant in type IV bone.

Materials: A prospective, multicenter (5 centers) study was conducted by examining the relationship between implant success and survival rates, and several patient and surgical parameters. The implants were placed in 82 patients who visited several nationwide dental hospitals and clinics between 2007 and 2008, followed by clinical and radiographic analyses.

Experimental study of bone response to hydroxyapatite coating implants: bone-implant contact and removal torque test.

Objective: The objective of this study was to evaluate the early osseointegration of hydroxyapatite (HA)-coated implant.

Study Design: Twelve adult male miniature pigs were used in this study. The removal torque of implants placed in the tibia of miniature pigs was measured.

Postoperative effects of anterior nasal spine bone harvesting on overall nasal shape.

Aim: Bone harvesting from the anterior nasal spine (ANS) is frequently used to correct peri-implant bone defects, particularly during implant placement in the anterior maxilla. However, many clinicians are concerned about the postoperative effect of removing the ANS on the nasal outline, as the ANS is integral to supporting the nose. This study aimed to describe the technique of ANS bone grafting and to investigate postoperative effects of bone harvesting from the ANS on the overall nasal shape.

Bony window repositioning without using a barrier membrane in the lateral approach for maxillary sinus bone grafts: clinical and radiologic results at 6 months.

Purpose: There has been considerable controversy about the placement of barrier membranes over osteotomy and graft sites in sinus bone grafts via the lateral window approach. Particularly when the sinus membrane remains intact, clinicians should consider the benefits and costs of a barrier membrane. This article presents clinical and radiologic findings following repositioning of a detached bony window without a barrier membrane in the lateral approach for maxillary sinus bone grafts.

The value of brachial-ankle pulse wave velocity as a predictor of coronary artery disease in high-risk patients.

Background And Objectives: Arterial stiffness has been known as an independent contributory factor for coronary artery disease (CAD). Brachial-ankle pulse wave velocity (baPWV) is widely used as a simple noninvasive measure of arterial stiffness. The aim of our study was to test whether baPWV had predictive value for CAD in the subset of patients with high pretest probability.

Evaluation of peri-implant tissue in nonsubmerged dental implants: a multicenter retrospective study.

Objectives: The objective of this study was to evaluate the peri-implant's hard and soft tissue response associated with the 1-stage, nonsubmerged, endosseous dental implant.

Study Design: A multicenter retrospective clinical evaluation was performed on 339 nonsubmerged implants placed in 108 patients at 5 clinical centers between January 2003 and December 2007.

Results: After a mean follow-up period of 30 months, the mean crestal bone resorption in 339 implants was 0.

Long-term exercise training attenuates age-related diastolic dysfunction: association of myocardial collagen cross-linking.

The incidence of diastolic heart failure increases dramatically with age. We investigated the impact of long-term exercise training on age-related diastolic dysfunction. Old (25-month-old) male Fischer 344 rats were studied after 12 weeks of treadmill exercise training or sedentary cage life (N=7, in each group).
