“…Some studies used radiographic evaluation to assess vertical alveolar bone loss 7 . However, CBCT analysis allows us to assess both horizontal and vertical alveolar bone changes 24‐26,38,52 . In this study CBCT analysis was performed according to a study by Jung et al 24 Most of the studies 11‐17 dimensional alveolar changes evaluated 4 to 7 months following tooth extraction.…”

“…Therefore, for successful implantation it is very important to preserve as much hard and soft tissue as possible, thereby reducing alveolar bone resorption and remodeling after tooth extraction 24,25 . Alveolar ridge remodeling proceeds immediately after tooth extraction and may interfere the implant placement in proper 3D position which then requires additional bone augmentation procedure 22,25,26 . Therefore, to reduce alveolar ridge dimensional changes, various alveolar ridge preservation techniques have been proposed 12,13 .…”

Objectives To evaluate alveolar ridge dimensional changes of different alveolar ridge preservation techniques after 3 months of tooth extraction and to compare the efficacy of autologous plasma rich in growth factor (PRGF) to the bone substitutes in alveolar ridge preservation and sites left to heal spontaneously. Materials and Methods Forty patients requiring tooth extraction in the anterior maxilla were randomly allocated to the four following treatment modalities: spontaneous healing (control), natural bovine bone mineral covered with resorbable native collagen membrane (BBM/CM), freeze‐dried bone allograft covered with resorbable native collagen membrane (FDBA/CM) and PRGF alone. Cone beam computed tomography (CBCT) scans were taken after surgery and 3 months later. The measurements of height and width (at 1, 3, and 5 mm below the crest) were performed after superimposing the 2 consecutive CBCT scans. Results The greatest horizontal alveolar bone resorption at 1 mm below bone crest was observed in the control group (−1.61 ± 1.76 mm, P = .037), whereas the least reduction in width was found in the BBM/CM group (−0.68 ± 0.67 mm, P = .037). The most pronounced alveolar height reduction was observed in the control group (−0.86 ± 0.43 mm), whereas alveolar ridge preservation with BBMC/CM (−0.26 ± 0.91 mm) and PRGF (−0.54 ± 0.86 mm) successfully reduced the alveolar height reduction as compared to the control group. Conclusions Alveolar ridge preservation technique in the esthetic zone using BBM/CM or using PRGF is beneficial to reduce horizontal and vertical bone changes.

“…Comparison of mean values from bone specimens between Endobon ® grafted sites and Bio-Oss ® grafted sites (Al Qabbani et al, 2018;Richardson et al, 1999). When conducting ARP, many variables can affect outcomes: type of wound closure, flap elevation, grafting material, use of a barrier membrane, use of growth factors, initial socket morphology, tooth position and type of arch, and timing of implant surgery (Bassir et al, 2018).…”

“…To counteract post-extraction bone resorption, alveolar ridge preservation (ARP) techniques can be used. As has been previously reported in both non-clinical and clinical studies, various types of augmentation (bone grafting) provide structural and dimensional stability (Al Qabbani et al, 2018;Klinge, Alberius, Isaksson, & Jonsson, 1992;Lee, Yi, Lee, & Kim, 2017;Richardson, Mellonig, Brunsvold, McDonnell, & Cochran, 1999). Compared with extraction alone, a reduction in loss of ridge height and width has been associated with ARP; however, no conclusive data are available to confirm esthetic and prosthodontic improvements secondary to ARP (Atieh et al, 2015;Avila-Ortiz, Chambrone, & Vignoletti, 2019;Iocca, Farcomeni, Pardinas Lopez, & Talib, 2017;MacBeth, Trullenque-Eriksson, Donos, & Mardas, 2017).…”

Objectives The purpose of this prospective, single‐center randomized pilot study was to histologically evaluate and compare vital bone development in premolar and molar‐extraction sites grafted with two different bovine‐derived xenografts. The secondary outcome of interest was implant survival in the grafted sites. Materials and Methods Adult patients in need of at least two tooth extractions were enrolled. A paired design was used; each patient received at least one of each type of graft at different sites. Each extraction site was randomized to one of two xenograft treatment groups. A resorbable membrane was always placed, and primary intention soft tissue closure was achieved. Four months later, implants were placed and a trephine drill was used to remove bone cores for histologic and histomorphometric analysis. Results Sixteen patients with 40 extraction sites were enrolled; 20 sites were grafted with one type of xenograft and 20 with another. Mean patient age was 53.5 years, and 65% of patients were male. Evaluation of bone core samples taken from grafted sites showed no significant difference in the mean value of percentage of new bone formation between the different grafted sites (33.4% and 32.4%, p = .76). Cumulative implant survival was 97.5% at the 24‐month follow‐up visit. Conclusion Within the limitations of this pilot study, no statistically significant differences in new bone growth between sites grafted with two different types of xenograft were found. Both graft materials promoted the formation of new bone and provided osseous support for implant placement after socket grafting.

“…It has been recommended to fill the space between the implant body and the bony walls of the extraction socket with allografts or, as we prefer, xenograft bone substitute materials 21,22 . Typically, these are placed after implant insertion to fill any existing gaps, which may leave hard‐to‐reach areas unfilled.…”

This article describes a comprehensive step‐by‐step protocol for immediate implant placement and restoration in the esthetic zone. Clinical Considerations Immediate implant placement into fresh extraction sockets and immediate restoration have become widely accepted, demonstrating long‐term success rates that are comparable with traditional delayed implant protocols. However, they are technique sensitive and require proper treatment planning as well as meticulous execution to be predictable and successful in the long term. This is particularly important in the esthetic zone, where even minor aberrations and mistakes can have devastating consequences, and especially in younger patients, where esthetic and functional outcomes should remain stable for years and possibly decades to come. The eight critical steps for predictable immediate implant placement include: provisional restoration of the failing tooth and presurgical phase, atraumatic tooth extraction, initial implant osteotomy, 3D bone graft packing, guided implant placement with a surgical guide, customized abutment insertion, provisional crown relining, and placement of a connective tissue graft from tuberosity. Immediate implant protocols in the esthetic zone require thorough planning and execution in the proper sequence. Each one of the critical steps discussed in this article has its own importance and challenges, which are critically assessed based on current scientific evidence.
