Shortened Treatment Time for Maxillary Sinus Grafting with Simultaneous Implant Placement: Retrospective Analysis with 10-Year Follow-Up.

Purpose: The aim of the present retrospective clinical study was to evaluate the outcome of a maxillary sinus lateral window augmentation protocol, which sought to shorten the treatment time.

Materials And Methods: This protocol entailed sinus augmentation with deproteinized bovine bone minerals (DBBM) and simultaneous implant placement in patients with minimal residual bone height. A total of 89 sinus augmentation procedures were performed in 74 patients, in whom 160 implants were placed between 2005 and 2013.

Peri-implantitis-associated methanogens: a preliminary report.

Methanogens have already been described in periodontitis but not in peri-implantitis. Thirty peri-implantitis samples and 28 control samples were collected in 28 consenting peri-implantitis patients. PCR-sequencing of the 16S rRNA gene was used as a broad-spectrum screening method and results were further confirmed by real-time quantitative PCR targeting the mcrA genes.
