Association between Keratinized Tissue width and Periodental Indices around Implant Supported Fixed Prosthesis

Presence of keratinized tissue around implants for maintaining peri-implant health and their long term stability has been a controversial issue. The aim of this study is to assess the correlation between the width of keratinized tissue and periodontal indices around implant-supporting fixed partial dentures.
In this cross-sectional study, 90 pateints who had implant-supported fixed partial dentures were divided into three groups with 30 patients in each one. Based on type of their prostheses it would be single crown, bridge or splinted. Peri-implant examinations were accomplished by means of measuring the width of keratinized mucosa (KM), the width of attached mucosa (AM), probing depth (PD), bleeding on probing (BOP), gingival recession (GR), gingival index (GI), and plaque index (PI) and collar metal show. The data was analyzed by Pearson & Spearman correlation test by SPSS20 software.
There was significant relationship between KM and AM in all groups (P With limitations of this study, it can be concluded that increasing the width of keratinized and attached mucosa is not necessarily associated with objective peri-implant health.
