“…The measurement of soft tissue changes over time is difficult when small alterations occur. In the past, different methods have been used including predominantly transmucosal probing, as well as ultrasonic devices [12,[37][38][39] and 2D measurements on CBCT slices [40,41]. The main disadvantage of these methods is that the data only pertain to one specific point of the implant site.…”

Background: Xenogeneic soft tissue substitutes are currently being investigated as an alternative to subepithelial connective tissue grafts (CTG) with the intention to avoid postoperative morbidity associated with autologous grafting. The aim of the present study was to volumetrically evaluate the effectiveness and mid-long-term stability of a porcine-derived collagen matrix (PDCM) (Mucoderm®, Botiss gmbh, Berlin, Germany) in increasing soft tissue volume at the buccal aspect of molar implant sites. Methods: Periodontally healthy non-smoking patients with a single tooth gap in the molar area were selected for a prospective case series. All sites had a bucco-oral bone dimension of at least 8 mm and demonstrated a horizontal alveolar defect. A wide diameter implant was placed under the elevated buccal flap and a PDCM was applied. The primary outcome was the linear increase in buccal soft tissue profile (BSP) within a well-defined area of interest. This was performed with designated software (SMOP; Swissmeda AG, Zurich, Switzerland) on the basis of superimposed digitalized study casts taken before surgery (T0), immediately after surgery (T1), at three months (T2), one year (T3) and three years (T4). Secondary outcomes were alveolar process deficiency and clinical parameters. Results: Fourteen out of 15 treated patients attended the three-year re-assessment (four females; mean age 51.4 years). Mean linear increase in BSP at T1 was 1.53 mm (p = 0.001). The PDCM showed substantial resorption at T2 (1.02 mm or 66.7%) (p = 0.001). Thereafter, a 0.66 mm volume gain was observed (p = 0.030), possibly due to the installation of a permanent crown displacing the soft tissues to the buccal aspect. This resulted in a linear increase in BSP of 1.17 mm (76.5%) at T4. Alveolar process deficiency significantly reduced over time (p = 0.004). However, 50% of patients still demonstrated a slight (6/14) or obvious (1/14) alveolar process deficiency at study termination. Implants demonstrated healthy clinical conditions. Conclusions: The PDCM demonstrated marked resorption during the early stages of healing. Due to the matrix thickening the tissues, and the permanent crown displacing the tissues, 76.5% of the initial increase in BSP could be maintained over a three-year period. Half of the patients failed to show perfect soft tissue convexity at the buccal aspect.

“…2 Researchers have worked on fractures and cracked teeth, 3 caries detection, 4 periapical lesions, 5 alveolar ridge and maxillofacial bones structures, 6 temporomandibular joints, 7 and on the measurements of soft tissue of the oral cavity, in particular of the gingiva and the masseter muscle. [8][9][10][11][12] Furthermore, it is possible to use ultrasounds to examine pathological structures, such as neoplastic lesions of the mucosa, 13 but also to detect the implant-abutment connection or to assess the margin of the alveolar ridge and the clinical attachment level, which can be used to evaluate the probing depth of the gingival sulcus and biologic width. 14 Nowadays, there is an increasing interest in evaluating the quality of the gingival margin.…”

Background. Successful periodontal and implant surgery as well as orthodontic treatment often depends on gingival and mucosal thickness. So far there has been no generally accepted protocol of measuring the thickness of gingiva by non-invasive methods.Objectives. The aim of the study was to evaluate the repeatability and reproducibility (%R&R) of the 20 MHz A-Scan ultrasonic device in measuring gingival thickness (GT) in the mucogingival complex. Material and methods.A 2-stage study utilizing non-invasive ultrasonic methods was conducted. In the 1st stage, 3 operators got calibrated by measuring previously established GT in porcine cadaver jaws. In the 2nd stage, 1 periodontally healthy subject was recruited in the study. Three operators performed the measurements of GT in maxillary left central and lateral incisors and canines, using the 20 MHz A-Scan ultrasonic device with a probe of 1.7 mm in diameter. The thickness was measured in 4 standardized points located in the free gingiva (FGT), supracrestal gingiva (SGT), crestal gingiva (CGT) and the mucosa (MGT).Results. The analysis of variance (ANOVA) method was used to quantify %R&R. The repeatability and reproducibility of the measurements was 8.4%. Interobserver reproducibility varied from 0.8% to 13.4%. The average intraobserver coefficient of variation (CV) was 6.6% (1.9-13.6%). The median of the reproducibility of all measurements was 8.1 %. Nevertheless, the median of CV was variable to the observer, i.e. 5.4%, 6.5%, 6.4%. Conclusions.The obtained results in %R&R prove the good recognition of methodology as well as the usefulness of the device. Non-invasive ultrasonic biometer GT measurements are crucial in periodontology as well as in other fields of dentistry.

“…Two different non-invasive methods of phenotype assessment were performed, the most commonly used in similar studies-gingival probe transparency [14,[17][18][19]27,28] and also less standard method-ultrasonic measurement [29][30][31] of an accurate thickness of gingival tissues. A comparison of both methods showed a signi cant correlation.…”

BackgroundPreservation of interdental papilla is an essential part of the functional and esthetic rehabilitation of dental treatment. It was described that thicker gingival tissues are more resistant to recession. The main objective of this investigation was to analyze if the gingival phenotype represents a potential risk factor affecting interdental papilla fill, height, or width in an esthetic region between central maxillary incisors. The secondary goals were: 1) analyze parameters describing papilla and the influence of a wide papilla basis for the vertical papillary dimension; 2) the correlation between different non-invasive measurements of gingival thickness; 3) comparison among both sexes.MethodsTogether, 54 periodontally healthy students (20–30 years old) were included in the study. Gingival thickness was measured using Pirop Ultrasonic Biometer. Phenotype was also assessed by gingival probe transparency. Papilla parameters - height and width of the interdental papilla were measured, and the degree of papilla recession was classified.ResultsNo significant correlation between papilla height, width, or papilla fill and gingival probe transparency or gingival thickness was found. Both methods of assessments of gingival phenotype showed a significant relationship. There was a significant correlation of papilla height and papilla fill. Papillae, which filled the interdental space completely, seem to be shorter. A strong positive association between papilla height and papilla width was revealed. Papillae were significantly higher in males.ConclusionThe appearance of interdental papillae could be influenced by various factors. Within the limitations of this study, results showed no significant correlation between the morphology of interdental papillae and soft tissue thickness. It seems that there is an influence of a wide papilla basis for its vertical dimension.
