Discriminant Analysis for the Thin Periodontal Biotype Based on the Data Acquired From Three‐Dimensional Virtual Models of Korean Young Adults

Abstract

PLSum5 >24 mm is the suggested criterion for identifying high-risk thin biotype patients based on the comparison with the results from gingival transparency inspection. A clinical reevaluation of this criterion should be examined in additional studies for application in real clinical situations.

Periodontal Biotype: Gingival Thickness as It Relates to Probe Visibility and Buccal Plate Thickness

“…A recent study suggested that if the sum of the lengths of the five papillae from maxillary canine to canine is >24 mm, the patient may be considered as having a thin biotype. 13 Although interesting, these data remain to be confirmed and have yet to gain clinical acceptance.…”

“…On the other hand, other studies have considered gingival biotype as a patient-specific factor. [12][13][14] A recent study by Cook et al 16 suggested that the periodontal biotype (thick or thin) at a patient level does translate into specific site-level factors, including probe visibility, papilla height, width of KT, and distance from the cemento-enamel junction (CEJ) to the alveolar crest.…”

“…However, nearly half of the thin‐scalloped patients are misclassified, which supports that simple visual assessment is of limited value to distinguish thick from thin biotypes. A recent study suggested that if the sum of the lengths of the five papillae from maxillary canine to canine is >24 mm, the patient may be considered as having a thin biotype 13 . Although interesting, these data remain to be confirmed and have yet to gain clinical acceptance.…”

“…Confusion may arise when reading the literature because, on one hand, the term of gingival biotype has been used interchangeably with tissue thickness 6‐8,10 or height of keratinized tissue (KT) 7 and was considered as a site‐specific factor. On the other hand, other studies have considered gingival biotype as a patient‐specific factor 12–14 . A recent study by Cook et al 16 suggested that the periodontal biotype (thick or thin) at a patient level does translate into specific site‐level factors, including probe visibility, papilla height, width of KT, and distance from the cemento‐enamel junction (CEJ) to the alveolar crest.…”

Relationship between the facial bone thickness and gingival biotype of the anterior maxilla in Koreans

“…치은을 통해 치주탐침자의 외형이 비치면 "얇은" 생체형(thin biotype)으로, 비치지 않으면 "두꺼운" 생체형"(thick biotype)으로 분류하였다. [23][24][25] 개인의 치은 생체형은 양 중절치에서 모두 치주탐침 자가 비치는 경우는 "얇은" 생체형으로, 그렇지 않은 경 우는 "두꺼운" 생체형으로 구분하였다. Table 1, 2).…”
