“…These results are consistent with those obtained in previous studies which have shown that horizontal bone loss of approximately 30~60% and vertical bone loss of approximately of 10~20% is inevitable after 6 months [39]. Despite the ridge preservation technique, postextraction bone atrophy appears to be entirely unavoidable [40].…”

Featured Application: Novel technology of bone regeneration.Abstract: The aim of this study was to evaluate the clinical, volumetric, radiographic, and histologic aspects of autogenous demineralized dentin matrix (DDM) combined with recombinant human bone morphogenetic protein-2 (rhBMP-2) used for ridge preservation, compared to those of deproteinized bovine bone with collagen (DBBC). Following atraumatic extraction, the socket was filled with DBBC, DDM, or rhBMP-2/DDM. Scanned images of dental casts and cone beam computed tomographs (CBCT) were superimposed for the calculation of soft and hard tissue volume alteration. Preoperative and postoperative measurements of the height and width of the alveolar ridge were compared using CBCT images. After 4 months, bone specimens were harvested for histomorphometric assessment. Loss of hard and soft tissue volume occurred at 4 months after extraction and ridge preservation in all groups. No volumetric differences were detected among the three groups before and 4 months after ridge preservation. The reduction in the horizontal width at 5 mm was higher in the DBBC compared to the DDM. Histologically, approximately 40% newly formed bone was founded in rhBMP-2/DDM group. The autogenous dentin matrix used to fill the socket was as beneficial for ridge preservation as conventional xenografts. The combination of rhBMP-2 with dentin matrix also demonstrated appreciable volumetric stability and higher new bone formation compared to DDM alone and DBBC.

“…The generalized lack of significant differences between the grafted and non-grafted sites as individually measured on axial, coronal and sagittal views may indicate that bone density may be similar between grafted and non-grafted sites following healing. The findings of this study correlate well with the systematic review by Horvath et al (19) on the comparison of alveolar ridge preservation versus unassisted socket healing. The authors have reported that there is conflicting evidence on the benefit of alveolar ridge preservation at the histological level, as it does not seem to promote de novo hard tissue formation routinely.…”

“…The remnants of the grafts often interfered with the normal healing process in line with preclinical results (19). Decreased bone density caused by the presence of residual graft particles might negatively affect the ability to obtain primary stability.…”

Volumetric changes of the alveolar ridge after socket preservation with various techniques have been investigated frequently. However, changes in bone density and quality of bone within the extraction sockets have seldom been studied. The purpose of this study was to evaluate the bone quality of grafted versus non-grafted socket sites prior to dental implant placement using Hounsfield unit (HU) values derived from cone-beam computed tomography (CBCT) imaging. The data was collected from 39 healed extraction sites reviewed over a one-year period. Subjects eligible for the study had a bone replacement graft and barrier membrane. Both study and control groups had CBCT scans performed immediately after extraction and four to five months after extraction for planning implant placement. HU values were measured from the CBCT scans and compared between groups. Intragroup variability was assessed utilizing standard deviation and standard error of the mean. Intergroup differences were evaluated using unpaired t-test. A generalized lack of significant difference in bone quality was observed between groups with the only statistically significant difference observed in the posterior maxilla. Future radiographic and histologic assessments of bone quality after socket preservation are required to determine the 'ideal' approach to preserve an extraction socket prior to implant placement.

“…Surgical complications after IIP are especially related to soft tissue alterations in consequence of a coronal shift of the gingival margin, which tend to follow the underlying bone after buccal bone plate remodeling. Importantly, recent studies [15][16][17] showed that alveolar ridge preservation and soft and hard tissue regeneration limit the resorptive process after tooth extraction.…”

Aim:The aim of this case report was to reconstruct the alveolar buccal bone plate lost in consequence of a root fracture in the maxillary central incisor area after immediate implant placement (IIP). A 48-year-old patient was referred to our office with the chief complaint of spontaneous bleeding in his left central incisor. After careful examination, the following comprehensive treatment approach was carried out: (1) Atraumatic tooth extraction, (2) IIP, (3) provisional prosthesis installation, (4) alveolar buccal bone plate reconstruction with autologous bone collected from the maxillary tuberosity, (5) gingival augmentation procedure with connective tissue graft removed from the palate, and finally (6) adjustment of the provisional restoration. After 1-year postoperative, an adequate esthetic outcome was achieved with lower cost, reduced morbidity to the patient, and lower treatment time. This approach was able to improve gingival architecture and bone volume with adequate thickness and width, enhancing patient esthetics and satisfaction. In conclusion, when proper diagnosis, precise surgical techniques, and appropriate multidisciplinary approach are employed, IIP followed by immediate dentoalveolar restoration might be considered a safe procedure to restore the peri-implant bone and gingival recession favoring the achievement of appropriate esthetic outcomes.Clinical significance: The treatment planning employed was able to improve gingival architecture and bone volume with sufficient width and thickness enhancing patient esthetics and satisfaction in one single-stage procedure.
