“…Therefore, a minimum thickness of 1.5 mm is advocated to provide additional protection and coverage of the augmented bone site. According to Tolman ( 27 ) and Brener ( 28 ) wound dehiscence was directly related to implant failure. Temporary mental paresthesia after harvesting chin grafts ranges from 10% to 50%, whereas the mandibular ramus ranges from 0% to 5% ( 29 , 30 ).…”

Aim: The purpose of this study was to systematically review clinical studies examining the survival and success rates of implants placed with intraoral onlay autogenous bone grafts to answer the following question: do ridge augmentations procedures with intraoral onlay block bone grafts in conjunction with or prior to implant placement influence implant outcome when compared with a control group (guided bone regeneration, alveolar distraction, native bone or short dental implants.)? Material and Method: An electronic data banks and hand searching were used to find relevant articles on vertical and lateral augmentation procedures performed with intraoral onlay block bone grafts for dental implant therapy published up to October 2013. Publications in English, on human subjects, with a controlled study design –involving at least one group with defects treated with intraoral onlay block bone grafts, more than five patients and a minimum follow-up of 12 months after prosthetic loading were included. Two reviewers extracted the data. Results: A total of 6 studies met the inclusion criteria: 4 studies on horizontal augmentation and 2 studies on vertical augmentation. Intraoperative complications were not reported. Most common postsurgical complications included mainly mucosal dehiscences (4 studies), bone graft or membrane exposures (3 studies), complete failures of block grafts (2 studies) and neurosensory alterations (4 studies). For lateral augmentation procedures, implant survival rates ranged from 96.9% to 100%, while for vertical augmentation they ranged from 89.5% to 100%. None article studied the soft tissues healing. Conclusions: Survival and success rates of implants placed in horizontally and vertically resorbed edentulous ridges reconstructed with block bone grafts are similar to those of implants placed in native bone, in distracted sites or with guided bone regeneration. More surgical challenges and morbidity arise from vertical augmentations, thus short implants may be a feasible option. Key words:Alveolar ridge augmentation, intraoral bone grafts, onlay grafts, block grafts, dental implants.

“…An autogenous bone graft is considered the best option because of its high boneinducing ability and low infection risk [7,8]. The autogenous bone graft is harvested from an adjacent or distant donor site within the same patient to reconstruct the deficiencies.…”

This study aimed to evaluate the bone regeneration capacity of a customized alloplastic material and xenograft with recombinant human bone morphogenetic protein-2 (rhBMP-2). We prepared hydroxyapatite (HA)/tricalcium phosphate (TCP) pure ceramic bone blocks made using a 3D printing system and added rhBMP-2 to both materials. In eight beagle dogs, a total of 32 defects were created on the lower jaws. The defective sites of the negative control group were left untreated (N group; 8 defects), and those in the positive control group were filled with particle-type Bio-Oss (P group; 12 defects). The defect sites in the experimental group were filled with 3D-printed synthetic bone blocks (3D group; 12 defects). Radiographic and histological evaluations were performed after healing periods of 6 and 12 weeks and showed no significant difference in new bone formation and total bone between the P and 3D groups. The 3D-printed custom HA/TCP graft with rhBMP-2 showed bone regeneration effects similar to that of particulate Bio-Oss with rhBMP-2. Through further study and development, the application of 3D-printed customized alloplastic grafts will be extended to various fields of bone regeneration.

“…Guided bone regeneration (GBR) is a surgical procedure to restore bone defects or deficiencies in the oral and maxillofacial region, for example, to increase the height and width of the alveolar ridge (Buser, Brägger, Lang, & Nyman, ; Buser, Dula, Belser, Hirt, & Berthold, ; Chiapasco & Zaniboni, ; Dahlin, Andersson, & Linde, ; Dahlin, Sennerby, Lekholm, Linde, & Nyman, ; Jung, Fenner, Hämmerle, & Zitzmann, ; Simion, Jovanovic, Tinti, & Benfenati, ). In this context, successful results with GBR in combination with all types of graft materials, that is autografts, allografts, xenografts, and alloplasts, have been shown (Benic & Hämmerle, ; Brener, ; Esposito, Grusovin, Coulthard, & Worthington, ; Proussaefs, Lozada, Kleinman, Rohrer, & McMillan, ). Nevertheless, there are significant differences among the various grafting materials of the same type.…”

Objectives To evaluate the effect of enamel matrix derivative in liquid form (EMD‐liquid) as adjunct to grafting with natural bovine bone (NBB), on new bone formation and osseointegration in buccal dehiscence defects at dental implants. Material and methods In six beagles, 3 months after extraction of the mandibular premolars and first molars. Three titanium implants (3.3 Ø × 8.0 mm) were inserted, and dehiscence‐type defects (mesiodistal width 3 mm × 5 mm depth) were created on their buccal aspect. The defects were randomly assigned to one of the following three treatment groups: Group 1: NBB, Group 2: NBB/EMD‐L, Group 3: Control. All sites were covered with a collagen membrane. Histomorphometric measurements were performed after 3 months of healing. Results New bone area, bone‐to‐implant contact (BIC), and first BIC (fBIC) in the NBB and NBB/EMD‐L groups were significantly greater than in the control group (p < .05). Further, f‐BIC was at a significantly more coronal position in the NBB + EMD‐liquid group (0.4 ± 0.1 mm) compared with the NBB group (1.2 ± 0.2 mm). Conclusions Natural bovine bone grafting enhances bone regeneration and osseointegration at implants with buccal bone dehiscences compared with no grafting, and adjunct use of EMD‐liquid appears to further enhance bone formation and osseointegration.
