Abstract

<abstract abstract-type="main" id="clr12083-abs-0001"> <title>Abstract</title> <sec id="clr12083-sec-0001" sec-type="section"> <title>Objectives</title> <p>This study aimed to determine bone level changes after 5–6 years of follow‐up for a large group of one‐stage dental implants consecutively placed in private practice. Potential confounding factors influencing crestal bone loss (CBL) were also assessed.</p> </sec> <sec id="clr12083-sec-0002" sec-type="section"> <title>Materials and methods</title> <p>A total of 378 transmucosal Straumann<sup>®</sup> implants in 174 patients were examined radiographically. Half of the study population (189 implants) had a titanium plasma sprayed (TPS) surface, and the other half (189 implants) were sandblasted and acid‐etched (SLA). Mean CBL was measured from 5 to 6 years post‐operative radiographs on the basis of known implant landmarks. Correlations of increased CBL with various independent variables were also investigated. Statistical analyses were performed using generalized estimating equations.</p> </sec> <sec id="clr12083-sec-0003" sec-type="section"> <title>Results</title> <p>Radiographic measurements showed a CBL ≤ 1.5 mm for 65% of studied implants. A CBL > 1.5 mm was found for 28% of implants, while 7% of implants had a CBL ≥ 3 mm. Three factors significantly influenced CBL (<italic>P</italic> < 0.05): implant surface texture (TPS > SLA), smoking status (smokers > non‐smokers), and implant location (anterior > posterior).</p> </sec> <sec id="clr12083-sec-0004" sec-type="section"> <title>Conclusions</title> <p>CBL was ≤1.5 mm after 5–6 years for the majority of followed implants. For implants with a CBL > 1.5 mm, statistically significant correlations were found for TPS surface type, anterior jaw locations, and smoking. Implant length did not influence CBL.</p> </sec> </abstract>
