Trends in funding, internationalization, and types of study for original articles published in five implant-related journals between 2005 and 2009.
The aims of this study were to evaluate the trends in funding, geographic origin, and study types of original articles in the dental implant literature and to investigate the relationships among these factors. ⋯ Almost half of the original dental implant articles were funded. The trend toward internationalization of authorship was evident. A strong association was observed between funding and geographic origin and between funding and study type. Most studies in North America and Europe were clinical studies and supported by industry, whereas a greater proportion of studies in Asia and South America were in vitro or animal studies funded through government resources.

Comparative StudyEvaluation of bone heating, immediate bone cell viability, and wear of high-resistance drills after the creation of implant osteotomies in rabbit tibias.
The purpose of this study was to evaluate the influence of reusing high-resistance drills on bone heating, immediate bone cell viability, and drill wear after performing implant osteotomies in rabbit tibias. ⋯ The tested drills did not cause significant bone heating after being reused 50 times; however, they caused more tissue trauma in the 50th osteotomy. Worn drills that are reused may be expected to cause excessive damage to the bone tissue and could adversely affect the osseointegration process.

Comparative StudyPublication bias in five dental implant journals: an observation from 2005 to 2009.
This study evaluated possible publication bias and its related factors in implant-related research over time. ⋯ There were a high number of implant-related studies reporting positive outcomes in the five selected journals. Some selected factors were associated with positive outcome bias. In general, funding was not associated with a positive outcome, except for animal studies. Industry-supported research did not show any association with the publication of positive outcomes.

The effects of recombinant human growth/differentiation factor-5 (rhGDF-5) on bone regeneration around titanium dental implants in barrier membrane-protected defects: a pilot study in the mandible of beagle dogs.
This dog study sought to evaluate guided bone regeneration (GBR) in peri-implant defects following implantation of beta-tricalcium phosphate (beta-TCP) with and without osteoinductive recombinant human growth/differentiation factor-5 (rhGDF-5). ⋯ Delivery of rhGDF-5 on beta-TCP might have the potential to enhance the results of GBR in peri-implant defects.

A meta-analytic approach to determine the state of the science on implant dentistry.
Meta-analyses have been widely used to estimate treatment effects in evidence-based dentistry. Few conferences, however, have used a systems approach to assure coherent data management and analysis. ⋯ This overview includes (a) a description of widely used clinical trial designs for implant dentistry, (b) a description of data management procedures specifically designed for the SSID conference, and (c) a description of the data analysis methodology, including descriptive analyses and meta-analyses. The use of the systems approach facilitated data abstraction and analysis.
