Gingival biotype and its relationship with the underlying bone thickness

Abstract

INTRODUCTION: The rehabilitation supported by an implant, in the anterior maxillary region, is a challenge of aesthetic point of view and your predictability take into account the gingival biotype and the width of the vestibular bone board. OBJECTIVE: The objective this work is verify the correlation between the thicknesses of the gingiva and the underlying bone for risk analysis in rehabilitation with osseointegratable implants. METHODS: Cone beam computer tomography (CBCT) of 32 dentated adult patients were analyzed (10 male/22 fem.). The measurement of the thickness of the soft tissues was done 2mm apical from the gingival margin of the anterior and premolar dental units, associated with the thickness of the buccal bone table, which was measured in at the three-thirds of the dental root. RESULTS: The gingival width between the thin (1,1mm) and the thick (1,6mm) biotypes was distinct, unlike the one found between female (1.3mm) and male (1.4mm). The thickness of the cervical vestibular bone board had no difference when comparing with the biotypes (0.33 - anterior region/0.53- posterior region). CONCLUSION: Gingival biotype do not suffer any influence from the gender or gingival biotype. Gingival biotype do not present any significant correlation when compared to the buccal bone plate width.
