Schincaglia, Gian Pietro; Thoma, Daniel S; Haas, Robert; Tutak, Marcin; Garcia, Abel; Taylor, Thomas D; Hämmerle, Christoph H F (2015). Randomized controlled multicenter study comparing short dental implants (6mm) versus longer dental implants (11-15mm) in combination with sinus floor elevation procedures. Part 2: clinical and radiographic outcomes at 1 year of loading. Journal of Clinical Periodontology, 42(11):1042-1051.

Abstract

AIM To compare, clinically and radiographically, short dental implants (6mm) to long implants (11-15 mm) placed with sinus grafting. METHODS Participants with 5-7 mm of bone height in the posterior maxilla were randomly allocated to receive short implants (GS) or long implants with sinus grafting (GG). Implants were loaded with single crowns 6 months after placement (PR). Patients were re-evaluated 12 months after loading (FU-1). Outcome variables included: Implant survival rate (CSR), marginal bone level alteration (MBL), periodontal probing depth (PPD), bleeding on probing (BoP), plaque control record (PCR) and crown-to-implant ratios (C/I). Statistical analysis was performed using non-parametric tests. RESULTS In 97 subjects, 132 implants were re-evaluated at FU-1. The CSR was 100%. The MBL from implant placement (IP) to (PR) was -0.22±0.4mm for GG and -0.3±0.45mm for GS (p<0.001). MBL from IP to FU-1 was -0.37±0.59mm for GG and -0.22±0.3mm for GS (p<0.001). Intergroup comparisons showed non significant differences for MBL (p>0.05), PPD (p=1) and PCR (p=0.09). BoP was higher in the GS (p=0.04). The C/I was 0.99 ±0.17 for GG and 1.86 ± 0.23 for GS (p<0.001). No correlation was observed between C/I and MBL, (GG: p=0.13; GS: p=0.38). CONCLUSIONS Both treatment modalities provided similar outcomes. This article is protected by copyright. All rights reserved.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
