Many treatment modalities have been introduced for correction of deficient alveolar ridge width. Bone expansion through the ridge split procedure is one of them. This technique was initiated in order to overcome many problems that usually associated with grafting procedures. The present study evaluated the effectiveness of piezoelectric device in performing ridge split using single-stage approach and assessed the outcomes during a period of about 4 months after surgery. A total of 23 patients ages in range between 18 and 60 years underwent ridge split procedure with immediate insertion of dental implants...

BACKGROUND: The prognosis of wide implants tends to be controversial. While wider implants were initially expected to result in a larger osseointegration area and have higher levels of primary stability, they were reported to have a relatively high rate of failure. The clinical outcome of ultrawide implants of more than 6 mm in diameter was evaluated through a retrospective study. METHODS: The investigation was conducted on patients who had received ultrawide implant (≥6 mm diameter) placements in Seoul National University Bundang Hospital from January 2008 to December 2013...

The aim of this study was to evaluate the correlation between resonance frequency analysis (RFA) values and the histomorphometric bone-implant contact (BIC) immediately after insertion of the implant. Additionally, it was examined to define which extent peak insertion torque (PIT) was correlated with the latter measurements. 15 Xive(®) S plus root from dental implants were inserted in fresh porcine frontal bones. The insertion torque was measured with the Kavo Intrasurg 300 surgical unit. RFA connector was coupled to the implants and the mean value of 20 consecutive RFA measurements was calculated via Osstell(®) ISQ device...

OBJECTIVE: In the last few decades the implantology has achieved excellent results in the prosthetic rehabilitation of the partially or totally edentulous patients. The clinicians, given the pressing demand by patients, must deal with the situations in which the lack of the availability and sometimes the low quality of the bone can lead to the treatment failure. Although the manufacturers recommend to follow codified surgical protocols, alternative techniques of preparation, apt to ensure a better primary implant stability, have been developed...

Several preclinical studies have shown that Escherichia coli-derived bone morphogenetic protein-2 (E-BMP-2) is as effective as mammalian cell-derived bone morphogenetic protein-2 (C-BMP-2) in the treatment of bone defects. However, further investigation of the effectiveness and determination of the optimal dosage of E-BMP-2 in large animals are still necessary before its full application in humans. This study investigated the efficiency of different concentrations of E-BMP-2 adsorbed in β-TCP for bone augmentation and osseointegration of immediate dental implants in a swine socket lift model...
