The Use of Cone Beam Computed Tomography to Assess Periodontal Biotype

Purpose of Review: Periodontal biotype is a concept with great relevance to clinical practice. Although numerous factors contribute to determining biotype, including soft/hard tissue thickness, soft/hard tissue contours, amount of keratinized tissue, and tooth shape, gingival thickness has been mostly utilized. The use of cone beam computed tomography (CBCT) has been recently proposed as a state-of-the-art approach for assessing periodontal biotypes because it provides information relative to both soft and hard tissue dimensions. Recent Findings: When used in conjunction with lip retraction or a dual-scan technique, reliable and reproducible measurements of gingival and alveolar thickness can be made on CBCT scans, with the potential to aid in periodontal biotype assessment. Summary: While current data support the potential use of CBCT for periodontal biotype assessment, the technology in its current state should be used primarily for investigational purposes. The cost and radiation dose need to be considered and additional research is required before implementation into clinical practice.
