Title Dimensional alterations of the buccal bone following dental implant placement and postoperative outcomes: - a systematic review

English abstract
Purpose: The purpose of this systematic review was to analyze the literature on alterations of the buccal bone dimensions following implant surgery, and what outcomes that were described in studies measuring the buccal bone thickness. Materials and methods: Medline, the Cochrane Library and the ISI Web of Science databases were searched to identify eligible human studies that measured the buccal bone thickness at delayed implant placement and followed the outcomes at least 12 months following implant placement. Results: From 834 identified publications, 3 were included. 2 of these were prospective clinical studies and 1 a systematic review. The included systematic review did not yield any additional information to the focused questions. Horizontal and vertical resorption of the buccal bone was demonstrated in both observational studies. Outcomes of hard and soft tissue changes were described as well as inflammatory state of the peri-implant mucosa. Conclusion: More research is needed concerning dimensional alterations of the buccal bone following implant placement due to methodological heterogeneity and lack of studies. No threshold regarding the buccal bone thickness and the degree of resorption could be identified. However, within the limitations of this review, results suggests that some horizontal and vertical buccal bone resorption may take place during the first 12 months following implant placement.
Swedish abstract
Syfte: Syftet med denna systematiska litteraturöversikt var att analysera litteraturen avseende dimensionsförändringar av det buckala benet efter implantatkirurgi samt att undersöka vilka resultat som beskrevs i studier som mätte det buckala benets tjocklek. Material och metoder: Databaserna Medline, Cochrane Library och ISI Web of Science genomsöktes för att identifiera relevanta humanstudier som mätte det buckala benets tjocklek vid implantatkirurgi och följde resultaten i åtminstone 12 månader efter implantatplaceringen. Resultat: Från 834 identifierade publikationer, inkluderades totalt 3. 2 av dessa var prospektiva kliniska studier och 1 en systematisk litteraturöversikt. Den inkluderade systematiska litteraturöversikten kunde inte ge någon ytterligare information till frågeställningen. Horisontell och vertikal resorption av det buckala benet visades i båda observationsstudierna. Resultat av hård- och mjukvävnadsförändringar beskrevs liksom det inflammatoriska tillståndet i mjukvävnaden runt implantatet. Slutsats: Mer forskning behövs om dimensionella förändringar av det buckala benet efter implantatkirurgi på grund av metodologisk heterogenitet och bristen på studier. Angående den buckala bentjockleken kunde inget tröskelvärde identifieras avseende vilken dimension som bidrog till minst andel resorption. Dock verkar det som om viss horisontell och vertikal resorption av det buckala benet kan ske inom loppet av 12 månader efter implantatkirurgi.
