“…Linear measurements of the augmented bone were performed rather than a volumetric analysis based on the available software. Although linear radiographic measurements provide valuable information regarding alveolar bone width gain, and have been used in similar studies (Hong, Chen, Kim, & Machtei, 2019), these measurements provide only a two‐dimensional assessment compared to a volumetric analysis achieved by superimposition of three‐dimensional images (Koerich, Weissheimer, Koerich, Luz, & Deeb, 2018).…”

Purpose The purpose of this study was to investigate if the addition of biologic agents to a particulate bone graft enhances horizontal ridge augmentation outcomes in terms of bone dimensions, bone density, and successful implant placement. Materials and Methods A retrospective chart review was done to assess the clinical and radiographic outcomes in 52 horizontal ridge augmentation sites in 43 patients. Information was gathered regarding surgical technique, type of graft material, biologic agents used (PRP or rhPDGF‐BB), method of space maintenance, and achieved alveolar ridge width and bone density changes as quantified on CBCT scans. Results The use of tenting screws, a resorbable membrane, and a combination of particulate allogenic and xenogenic bone graft material provided an average horizontal bone gain of 3.6 mm in the 52 augmented sites. There was no statistically significant difference observed in the amount of horizontal bone gain between sites treated with the addition of biologic agents (n = 21), or with a particulate bone graft alone (n = 31). A marginally statistically significant difference was found in the density of the grafted bone with the addition of biologics (p value = .0653). Conclusion The addition of biologic agents to the graft materials did not have a significant effect on the amount of horizontal bone gain or successful implant placement; however, it marginally enhanced the bone density of the grafted area.

“…The 2‐year postoperative CBCT scan (CBCT post ) was compared to the preoperative scan (CBCT pre ) to assess alveolar ridge dimensional changes, particularly on the buccal aspect. The DICOM files of CBCT pre and CBCT post were imported to OnDemand 3D v1.0.10.7520 (Cybermed Inc) software for image reconstruction and loaded using the fusion module (Koerich et al, 2018) allowing exact superimposition of the images (Figure 3). On the CBCT pre , the level of the buccal crest of bone was determined and marked (0) in addition to 2, 4, and 6 mm apical to the buccal crest of bone (which coincide with the device groove levels; G1‐BCL, G2‐IPL, G3‐IP2, G4‐IP4 respectively).…”

Objectives To compare esthetics at single immediately placed implants with and without soft tissue augmentation. Materials and Methods Patients with non‐restorable maxillary teeth in the esthetic zone were assigned into 2 groups: immediately placed implants with simultaneous vascularized interpositional periosteal connective tissue grafting (VIP‐CTG) or non‐grafted immediately placed implants (NG). The outcomes included: pink esthetic score (PES), gingival thickness, keratinized tissue width, buccal bone changes, marginal bone loss, pain, and satisfaction. Results Eighteen implants were included. At 2 years the mean value for PES was 12 ± 3.2 for the VIP‐CTG and 12.9 ± 1.3 for the NG (p = .855). Mucosal thickness and keratinized tissue width showed no statistically significant difference between the two groups (p = .253) and (p = .931) respectively. Clinically buccal bone showed mean bone loss of 2.03 ± 1.57 mm for VIP‐CTG and 1.09 ± 1.3 mm for NG (p = .247) and radiographically showed 1.67 ± 0.84 mm at the VIP‐CTG and 1.16 ± 0.47 mm at the NG (p = .118). No statistically significant difference between both groups was demonstrated regarding marginal bone level changes (p = .142), pain (p = .622), or satisfaction (p = .562) at any time point. Conclusion Simultaneous soft tissue grafting with immediate implant placement did not provide a more favorable outcome regarding esthetics or alveolar bone preservation effect. Undisturbed healing with the least surgical intervention seems to provide more favorable outcomes.

“…In most orthognathic surgery cases, there are postoperative adaptations in the mandibular position that may change both occlusion and condylar position over time. Therefore, cranial base superimposition can be used for condylar displacement evaluation, but it is not appropriate for the study of condylar morphological changes 21 .…”

“…Recent studies have shown the potential use of maxillary and mandibular voxel-based regional superimposition for bone graft assessment, implant positioning accuracy, and alveolar resorption 19,21 . Besides that, the authors stated regional superimposition is the ideal technique for morphologic evaluation such as condylar resorption or hyperplasia 20 .…”
