ABSTRACT

Aim. The purpose of this systematic review was to investigate the literature available

regarding long-term stability of different bone augmentation materials in combination with dental implant treatment.

Material and methods. An electronic search was done using PubMed and Web of Science.

Blocks with keywords were constructed and inserted into the search engines to find studies involving implant treatment in combination with bone augmentation, with a radiographic follow-up of at least 2 years. Found articles were reviewed in relation to predetermined inclusion- and exclusion criteria. Data from included studies was extracted. Included studies were assessed of risk of bias according to modified protocols.

Results. The electronic search yielded 1183 studies. 14 studies using either autogenous,

allogeneic, xenogeneic or alloplastic augmentation materials was included in this review. The results from the data extraction process showed a wide variation in both materials and

techniques used.

Conclusion. The general conclusion drawn from this study is that marginal bone loss around

dental implants placed in augmented bone does not exceed 1 mm within two years post-operatively. A more precise conclusion regarding marginal bone level stability could not be drawn due to the heterogeneity of the included studies. There is a need for additional high-quality studies with long-term follow-up, investigating and comparing marginal bone level stability for different bone augmentation materials.

SAMMANFATTNING

Syfte. Syftet med denna systematiska litteraturöversikt var att undersöka det vetenskapliga

underlaget avseende långsiktig stabilitet hos olika typer av benersättningsmaterial i kombination med implantatinstallation.

Material och metod. En elektronisk sökning gjordes med hjälp av PubMed och Web of

Science. Block med sökord konstruerades och skrevs in i sökmotorerna för att hitta studier med implantatbehandling i kombination med benaugmentation, med en radiologisk

uppföljning efter minst 2 år. Funna artiklar granskades i förhållande till förutbestämda inklusions- och exklusionskriterier. Data från inkluderade studier registrerades. Risken för bias i de inkluderade studierna bedömdes enligt modifierade protokoll.

Resultat. Den elektroniska sökningen resulterade i 1183 studier, varav 14 studier med

antingen autogent, allogent, xenogent eller alloplastiskt benersättningsmaterial inkluderades i denna litteraturöversikt. Resultatet från studierna visade en stor skillnad i både tekniker och material.

Slutsats. Den generella slutsatsen i denna studie är att den marginella benförlusten vid dentala

implantat som placerats i augmenterat ben inte överstiger 1 mm inom två år. En mer exakt slutsats om den marginella bennivåns stabilitet kunde inte dras på grund av de stora skillnaderna mellan de inkluderade studierna. Det finns ett behov av fler högkvalitativa studier med långtidsuppföljning som undersöker och jämför den marginella bennivåns stabilitet för olika benersättningsmaterial.
