Most of the digital imaging techniques have not yet sufficiently been validated to be used for outcome measures in implant dentistry. In clinical research, cone beam CT (CBCT) is increasingly being used for 3D assessment of bone and soft tissue following augmentation procedures and implant placement. Currently, there are no effective methods for the reduction of artifacts around implants in CBCT. Optical scanning is being used for the 3D assessment of changes in the soft tissue contour. The combination of optical scan with pre-operative CBCT allows the determination of the implant position and its spatial relation to anatomical structures. Spectrophotometry is the method most commonly used to objectively assess the color match of reconstructions and peri-implant mucosa to natural dentition and gingiva. New optical imaging techniques may be considered possible approaches for monitoring peri-implant soft tissue health. MRI and ultrasonography appear promising non-ionizing radiation imaging modalities for the assessment of soft tissue and bone defect morphologies. Optical scanners and OCT may represent efficient clinical methods for accurate assessment of the misfit between the reconstructions and the implants.

“…In addition, CBCT was used to visualize the external contour of the peri-implant soft tissue (Kehl et al 2011;Benic et al 2012a;Kaminaka et al 2014;Jung et al 2015). This can be accomplished by applying radio-opaque contrast materials (e.g.…”

“…They suggested using lip and tongue retractors while scanning to prevent the collapse of the soft tissues of lips and cheeks on the facial gingiva, as the low resolution of density and contrast of the soft tissues prevent the visualization of buccal mucosa. Some studies indicate that using retractors or cotton rolls may apply pressure on soft tissues causing dimensional alterations . In a study by Yilmaz et al, the palatal masticatory mucosa thickness was measured using CBCT images and high contrast and resolution medical lcd displays were used to detect the soft tissue structures to make a proper measurement.…”

“…Also, the pressure applied during the measurement can affect the final outcome. On the other hand, CBCT provides high quality three‐dimensional diagnostic images of hard tissues, but it is not useful in soft tissue imaging due to the low resolution and contrast . To evaluate the soft tissue thickness in CBCT scans, radiopaque materials were placed over the soft tissue .…”

Objective The aim of this study was to introduce a novel soft tissue thickness measurement method using cone beam computed tomography (CBCT) and to compare the new method with ultrasonic device applications and transgingival probing measurements. Methods Twenty‐five participants (12 female, 13 male, age range, 25‐51 years) were included the study. Soft tissue thickness in lateral incisor, canine, premolar, and molar regions were measured using transgingival probing (group T), ultrasonic device (group U), and CBCT scan measurements (group C). Differences and correlations between groups and agreement between measurement methods were evaluated. Results Soft tissue thickness was significantly lower in group U in premolar region, but was significantly higher in molar region compared with group C and group T (P < .05). There were significant positive correlations in lateral incisor and canine region, between group U and group C, in premolar region between group T and group C, and in molar region between group U and group C, and between group C and group T (P < .05). The highest agreement between measurement methods was evident between group T and group C. Conclusion Soft tissue thickness values in maxilla may differ depending on the measurement method and location of the measurement. Ultrasonic device, transgingival probing, and CBCT measures may not necessarily correlate in all locations. The high agreement between CBCT measurements and transgingival probing may suggest the newly introduced method as a promising technique for soft tissue thickness evaluation. Clinical Significance This study evaluated the relation between different soft tissue thickness measurement methods and demonstrated a novel method which can be used in any part of the mouth. The outcome also suggested that the measurement method and the location might affect the soft tissue thickness value obtained, and therefore might be important in clinical decision making.

“…At the one‐year follow‐up examination the marginal bone loss at the implants in the thin group was in the magnitude of 1.5 mm, whereas the thick group only measured around 0.3 mm. Implant abutment connections were evaluated in another study . In addition, the investigators analyzed the effects of the buccal soft tissue thickness on marginal bone level changes in 32 patients.…”

The etiology of hard‐ and soft‐tissue deficiencies at dental implants: A narrative review

Hard- and soft-tissue deficiencies at implant sites may result from a multitude of factors. They encompass natural resorption processes following tooth extraction, trauma, infectious diseases such as periodontitis, peri-implantitis, endodontic infections, growth and development, expansion of the sinus floor, anatomical preconditions, mechanical overload, thin soft tissues, lack of keratinized mucosa, malpositioning of implants, migration of teeth, lifelong growth, and systemic diseases. When more than one factor leading to hard and/or soft-tissue deficiencies appear together, the severity of the resulting condition may increase. Efforts should be made to better identify the relative importance of these etiological factors, and to develop strategies to counteract their negative effects on our patient's wellbeing.
