This 1-year prospective study evaluated horizontal and vertical facial gingival tissue changes after immediate implant placement and provisionalization (IIPP) with and without bone graft in the implant-socket gap (ISG). During IIPP, 10 patients received bone graft material in the ISG (G group), while the other 10 patients did not (NG group). The implants were evaluated for implant stability quotient (ISQ), modified plaque index (mPI), modified bleeding index (mBI), marginal bone level (MBL), facial gingival level (FGL), and facial gingival profile (FGP) changes. The mean ISQ value at 9-month follow-up was statistically significantly greater than on the day of implant surgery (P < .05). The mPI and mBI scores demonstrated that patients were able to maintain a good level of hygiene. There were no statistically significant differences in the mean MBL changes between the G and NG groups (P > .05). There were statistically significant differences in FGL changes between the G (-0.77 mm) and NG (-1.35 mm) groups (P = .035). There were no statistically significant differences in FGP changes between the G and NG groups (P > .05). However, statistically significant differences were noted in FGP change between the 3–12 and 0–12 month intervals in both groups (P < .05). Within the limitations of this study, although no significant differences were noted in FGP changes between groups, G group experienced significantly less FGL changes than NG group. Bone graft material placement into ISG seems to be advantageous for tissue preservation during IIPP. However, future long-term studies, with larger sample size, are needed to validate the efficacy of such procedure

Preservation of the dental extraction sockets through bone grafting has been a key procedure to maintain the volumetric aspect of the bone walls. This has been proven successful in bone preservation for future implant insertion or prosthetic treatment. Several materials of bone allograft, xenografts, synthetics and membranes were successful in socket preservation however the healing duration and the outcome of bone formed differs. Ten patients selected with posterior extraction sockets for the augmentation procedure, the bone graft mass mixed with Amnio-Spark fluid (Salvin Dental Specialties, Charlotte, NC, USA) and the wound secured with sutures and left to heal with no covering membrane. Post-operative visits scheduled at two, four and twelve weeks’ intervals for monitoring of the healing and core biopsies were harvested from the augmented extraction sockets and examined histologically at the twelve’s week. At two weeks, there was considerable formation of tissue covering the bone graft material which continued to progress into keratinized tissue in four weeks. Core bone biopsies taken at twelve weeks demonstrated a pattern of viable bone formation with minor remnants of the bone graft material. This case series will demonstrate the effectiveness of the amnio- fluid in rapid formation of gingival tissue on top of the augmented extraction socket wounds. Additionally, it will histologically confirm expedited bone remodeling into the extraction socket following the augmentation

Composite Bone

The material properties of nanocellulose (NC) can effectively enhance the structural stability of composite materials. However, the research related to NC/α-calcium sulfate hemihydrate (CSH) composites is largely lacking. In this paper, we explore the combination of these two materials and determine their elaborate biological activities in vivo. Using α-CSH as the matrix, the composite bone graft materials were produced according to different proportions of NC. Then the mechanical strength of the composite bone graft was measured, and the results were analyzed by X-ray diffraction and scanning electron microscopy (SEM). To conduct the material in vivo evaluation, 0% (CN0) and 0.75% (CN0.75) NC/α-CSH composite bone graft materials were implanted into a femoral condyle defect model. The results indicated that NC could significantly enhance the mechanical properties of α-CSH. The SEM analysis indicated that the NC shuttled between the crystal gaps and formed a three-dimensional network structure, which was firmly combined with the crystal structure. Meanwhile, the CN0.75 scaffold remained at 12 weeks postoperation, which provided a long-term framework for new bone formation. Overall, our findings demonstrate that, with a 0.75% NC/α-CSH composite demonstrating good potential as a bone graft material for clinical bone grafting.
