“…To compensate for this occurrence, overcorrection of the horizontal defects should be taken into consideration. Mordini et al [41] showed 5% ± 3.78% resorption rates from 4 to 6 months after guided bone regeneration in posterior mandible affected by horizontal bone loss.…”

Trauma is a worldwide cause of millions of deaths and severe injuries every year, all over the world. Despite the limited extension of the oral region compared to the whole body, dental and oral injuries account for a fairly high percentage of all body traumas. Among head and neck traumas, dental and facial injuries are highly correlated to sport activities, and their management can be a real challenge for practitioners of any specialty. In case of trauma directed to periodontal structures, restorative and endodontic solutions may not be sufficient to achieve a definitive and long-lasting treatment. This article aims to illustrate surgical options and appliances to prevent dental injuries that may be available to the clinicians treating dental trauma involving oral soft and hard tissues.

“…Li et al (2019Li et al ( , 2020 reported an E res for a GBR combined with immediate implant placement (6 months of healing) of 52% (ranging from 28% to 60%), with a linear resorption of 19% (3%-36%) at 2 mm distance from the implant shoulder. Mordini et al (2020) examined the resorption of a freeze-dried bone allograft (FDBA) and a resorbable collagen membrane 4 and 6 months after GBR (thus E res ) via stone cast models and observed a resorption of 5% ± 4%. The degree of graft resorption was higher when primarily non-contained defects were included (Benic et al, 2019).…”

Individual “alveolar phenotype” limits dimensions of lateral bone augmentation

Aim Alveolar ridge resorption following tooth extraction often renders a lateral bone augmentation inevitable. Some patients, however, suffer from severe early (during graft healing, Eres) and/or late (during follow‐up, Lres) graft resorption. We explored the hypothesis that the “individual phenotypic dimensions” may partially explain the degree of such resorptions. Materials and Methods Patients who underwent a guided bone regeneration (GBR) procedure were screened for inclusion according to the following criteria: (1) a relatively symmetrical maxillary arch; (2) an intact contra‐lateral alveolar bone dimension; (3) the availability of a pre‐operative cone‐beam CT (CBCT); (4) a CBCT taken immediately after GBR, and (5) at least one CBCT scan ≥6 months after surgery. CBCT scans from different timepoints were registered and imported into the Mimics software (Materialise, Leuven, Belgium). Bone dimensions of the contra‐lateral site of the augmentation, representing the “individual phenotypical dimension (IPD) of the alveolar crest”, were superimposed on the augmented site and registered accordingly. As such, Eres and Lres could be measured over time, in relation to the IPD (in two dimensions; per millimetre apically from the alveolar crest, in the centre of the GBR), as well as in three dimensions (the entire GBR, 2 mm away from the mesial, distal, and apical border for standardization). Results A total of 17 patients (23 augmented sites) were included. After Eres, the outline of the augmentation was in general located ±1 mm outside the IPD, but ≥1.5 years after GBR, it further moved towards the IPD (85% within 0.5 mm distance). Conclusions Within the limitations of this study, the results indicate that the dimensions of a lateral bone augmentation are defined by the “individual phenotypic bone boundaries” of the patient.

“…The volume changes exhibited by 3DHA after six months were similar to those of the lateral GBR using freeze-dried bone allograft (FDBA). However, a different analysis based on polyvinylsiloxane impression showed a volume change of 247.0 ± 114.1 mm 3 [56]. The 3D volumetric analysis of bone in our study was calculated from the CBCT of the baseline and at 6 months, which has no bias from soft-tissue thickness.…”

Customized 3D printed nanohydroxyapatite bone block grafts for implant sites: A case series

et al. 2022

Patients: A case series of 12 patients (mean age, 53.5 years) with horizontal ridge deficiencies had augmentations with customized 3D printed nanohydroxyapatite (3DHA) block grafts prior to implant placement. 3DHA graft materials were fabricated to fit the individual patient defects using DICOMs from CBCT images obtained from each patient. The CBCT images were then converted into the STL file format and 3DHA was reconstructed by 3D printing. Surgical bone augmentation consisted of 3DHA incorporating concentrated growth factors (CGFs) and platelet-rich fibrin (PRF) membrane. At 6 months, a bone biopsy and implantation were performed. The primary outcome was horizontal bone gain after 6 months. The secondary outcomes included information on the clinical outcomes, dimensions, and histomorphometric results. Discussion: The 3DHA block graft was successful in 10 of 12 patients. Graft adjustment was not required. All 3DHA adapted and fit well at all defect sites. Maximum mean horizontal bone gains were 3.06 ± 1.02 and 3.56 ± 0.23 mm from the DICOMs and STL data sets, respectively. The volume gain was 229.8 ± 82.96 mm 3 . A low pain score after surgery was reported of 1.41 ± 0.51, while the healing index score increased with a maximum mean of 4.7 ± 0.67. Thirteen implants were placed with good primary stability (ISQ = 65 ± 4.08), without additional guided bone regeneration. Histomorphometric analysis revealed that new bone formation,
