The association of buccal keratinized tissue width and periodontal biotype on soft tissue surrounding dental implant. M Dent J. 2014; 34(3): 311-20.0125-5614 (printed)https://repository.li.mahidol.ac.th/handle/20.500.14594/1068Objectives: To compare clinical outcomes surrounding dental implants between narrow and wide buccal keratinized tissue and between thin and thick periodontal biotype. Materials and methods: Fifty one patients recruited from the patient’s bank of Oral medicine and Periodontology, Faculty of dentistry, Mahidol University. Eighty two functioning dental implants were examined. All implants mucosa were divided into 2categories: 1) keratinized mucosal width was divided into wide (≥ 2 mm) and narrow (< 2 mm), 2) keratinized mucosal thickness was divided into thick and thin. Clinical parameters included gingival index (GI), plaque index (PI), bleeding index (BI), probing depth (PD), buccal mucosal recession and periodontal attachment were determined. Peri-implant crevicular fluid was collected for measurement by periotron. Results: The implant areas that had thick or wide mucosa showed more probing depth than those that had thin or narrow mucosa, significantly (P= 0.001, P=0.008, in order). The periotron value in thin or narrow mucosa had significantly greater than thick or wide mucosal sites (P=0.016, 0.042 orderly). There was no correlation between keratinized tissue thickness or width and GI, BI and PI. Thin mucosa tend to occur buccal recession than thick mucosa, but not significant though. Conclusion: The finding of this study showed that keratinized mucosal thickness and width surrounding implants affected the peri-implant soft tissue status.engMahidol UniversityImplantsMucosal thicknessMucosal widthPeri-implant inflammationPeri-implant soft tissuePeriodontal parametersOpen Access articleวิทยาสารทันตแพทยศาสตร์มหิดลMahidol Dental JournalArticleFaculty of Dentistry Mahidol University
