“…Also, maximum graft resorption occurs within the first year of graft placement. By placing implants simultaneously and early loading of the graft, the functional stimulus could lead to less resorption and further stability [ 21 ]. Lofano et al approve the same findings and believe that the disuse following latent implant placement could lead to bone resorption, especially with onlay bone grafting [ 22 ].…”

Objectives. To reconstruct and rehabilitate a severely atrophied mandible. Case presentation. A 40-year-old female patient with the chief complaint of denture instability was admitted to our care. In our opinion, the optimum reconstructive method for their severely atrophied mandible (width of 4 mm) was bone grafting with an inverted sandwich technique. 2 split-thickness autogenous calvarial grafts were attained. 4 onlay bone blocks were prepared, placed with an inverted sandwich technique, and fixed with 8 lag screws. 4 implants (Osstem, ⌀4×10 mm) were placed simultaneously, and an immediate post-operation cone beam computed tomography confirmed the proper placement of the grafts and implants. No complications were reported within 4 and 8 months following graft and implant placement. Final impressions for full dental rehabilitation were taken at the 8-month follow-up. Conclusion. Split-thickness calvarial grafts and simultaneous implant placement seem to be a very efficient and promising approach for major reconstruction of the mandible. However, further studies are recommended.

“…SLA can form a micron-scale reticulated multi-level hole structure on the surface of the implant, which is beneficial to the proliferation, adhesion, and migration of bone marrow mesenchymal stem cells, and increases the adsorption of monocyte–macrophages, platelets, and fibrin. The SLA surface can also promote the expression of pro-angiogenesis-related genes such as VEGF and PDGF, making it have good osteocompatibility . On the other hand, this structure increases the contact area between the implant and the bone tissue, which is more conducive to stress distribution.…”

To address the problem of insufficient bone mass in the implant area, we focused on the vertical increment of the posterior mandibular area to increase bone mass with the aid of a healing abutment. Data of patients with insufficient vertical bone height in the posterior mandibular area were collected, and vertical increment of alveolar bone operations was performed with the aid of a healing abutment. Preoperative residual alveolar bone height, immediate postoperative alveolar bone height, and 6-month postoperative alveolar bone height were recorded, with peri-implant soft tissue results 6 months after surgery using the modified plaque index and sulcus bleeding index. Twelve patients, aged 42–73 years, with an average age of 55.91 ± 11.58 years, received vertical bone augmentation in the posterior mandibular region supported by implant healing abutments. Fifteen SLA TSIII OSSTEM implants were utilized in the 12 patients; one patient failed in vertical bone augmentation at one site (H0 = 0 mm). The vertical bone augmentation effect of two patients at two sites was 0 mm < H0 < 1 mm, and the vertical bone augmentation effect of 12 sites in nine patients was H0 ≥ 1 mm. The implant success rate was 93.3%, and the mean vertical bone gain was 2.91 mm. Peri-implant soft tissue parameters are as follows: mean modified plaque index, 1.92; mean modified sulcus bleeding index, 1.21; and mean probing depth, 3.18. No clinically observable complications occurred. Bone augmentation supported by the implant healing abutment showed the characteristics of “platform transfer”, with good formation of the implant–bone interface. The bone augmentation surgery was completed at the same time as the implant placement, which reduced the pain of multiple operations and shortened waiting times. We provide a novel idea to solve the problem of insufficient vertical bone height in the posterior mandibular region.

“…Recent in vivo studies and reviews analysed the application of CAD/CAM milled and 3D printed bone grafts and recognised their future potential, though there is currently need for additional research (Tuna et al, 2021;Yen & Stathopoulou, 2018). Therefore, there is rather the question whether an implant can be osseointegrated on the vestibular side by a transplanted block graft, needing vascularisation and consecutive bone remodelling itself (Ma et al, 2021). This, however, is shown by various clinical studies, analysing the capacity of implant osseointegration following same stage bone block fixation (Michalczik & Terheyden, 2007).…”

Aim To assess in vitro the workflow for alveolar ridge augmentation with customised 3D printed block grafts and simultaneous computer‐assisted implant planning and placement. Methods Twenty resin mandible models with an edentulous area and horizontal ridge defect in the region 34–36 were scanned with cone beam computed tomography (CBCT). A block graft for horizontal ridge augmentation in the region 34–36 and an implant in the position 35 were digitally planned. Twenty block grafts were 3D printed out of resin and one template for guided implant placement were stereolithographically produced. The resin block grafts were positioned onto the ridge defects and stabilised with two fixation screws each. Subsequently, one implant was inserted in the position 35 through the corresponding template for guided implant placement. Optical scans of the study models together with the fixated block graft were performed prior to and after implant placement. The scans taken after block grafting were superimposed with the virtual block grafting plan through a best‐fit algorithm, and the linear deviation between the planned and the achieved block positions was calculated. The precision of the block fixation was obtained by superimposing the 20 scans taken after grafting and calculating the deviation between the corresponding resin blocks. The superimposition between the scans taken after and prior to implant placement was performed to measure a possible displacement in the block position induced by guided implant placement. The (98–2%)/2 percentile value was determined as a parameter for surface deviation. Results The mean deviation in the position of the block graft compared to the virtual plan amounted to 0.79 ± 0.13 mm. The mean deviation between the positions of the 20 block grafts measured 0.47 ± 0.2 mm, indicating a clinically acceptable precision. Guided implant placement induced a mean shift of 0.16 ± 0.06 mm in the position of the block graft. Conclusions Within the limitations of this in vitro study, it can be concluded that customised block grafts fabricated through CBCT, computer‐assisted design and 3D printing allow alveolar ridge augmentation with clinically acceptable predictability and reproducibility. Computer‐assisted implant planning and placement can be performed simultaneously with computer‐assisted block grafting leading to clinically non‐relevant dislocation of block grafts.
