Nonincised Papillae Surgical Approach (NIPSA) in Periodontal Regeneration: Preliminary Results of a Case Series. Moreno Rodriguez JA, Caffesse RG. Int J Periodontics Restorative Dent. 2018;38(Suppl):s105-s111. https://www.ncbi.nlm.nih.gov/pubmed/30118534   This case series aims to clinically evaluate a new surgical approach to treat periodontal intrabony defects in conjunction with cerabone® and Emdogain®. Surgically, the defects are accessed via the alveolar mucosa preserving the interdental tissues (Nonincised Papillae Surgical Approach, NIPSA). Methods: Ten patients diagnosed with periodontal intrabony defects with a mean probing pocket depth (PPD) of 9.6 ± 2.3 mm were treated with the Nonincised Surgical Approach (NIPSA) in conjunction with cerabone® and Emdogain®. PPD reduction, clinical attachment level gain (CAL), keratinized tissue width and recessions were recorded six to 18 months post-surgery. Results: Healing was uneventful in all cases. PPD decreased to 2.3 ± 0.5 mm and a CAL gain of 7.3 ± 2.4 mm was found. Gingival papilla height, keratinized tissue width and buccal gingival margin remained stable over time....

The use of mineralized bone allograft (C+TBA) as a single grafting material in maxillary sinus lifting with severely atrophied alveolar ridge (1–3mm) and immediately inserted dental implants. A 3- up to 8-year retrospective study Tilaveridis I. et al, 2018 Oral and Maxillofacial Surgery http://www.ncbi.nlm.nih.gov/pubmed/29858723   OBJECTIVE: The primary aim of our study was to evaluate the efficacy of mineralized bone allograft alone in sinus floor augmentation with simultaneous implant placement in cases with severe atrophy of the residual maxillary bone (bone height < 4 mm). METHODS: Thirty-five dental implants were placed in 29 patients who underwent sinus augmentation via traditional lateral window technique from 2008 to 2013. Patients with residual alveolar height between 1 and 3 mm at the site of implantation were included in the study. The height of residual bone was initially estimated by plain panoramic X-ray and reevaluated intraoperatively by precise micrometric measurement at the site of implantation. Implants of 13 mm height and 3.5...

The Use of a Novel Porcine Derived Acellular Dermal Matrix (mucoderm) in Peri-Implant Soft Tissue Augmentation: Preliminary Results of a Prospective Pilot Cohort Study. Papi P. and Pompa G. BioMed Research International 2018. https://www.hindawi.com/journals/bmri/2018/6406051/   Study aim and design: pilot prospective study to present the one-year follow-up results of mucoderm® in peri-implant soft tissue augmentation procedures dental implants were placed in the upper premolar area of 12 patients, at implant uncovering after 8 weeks mucoderm® was inserted the keratinized mucosa width (KMW) gain was considered as primary outcome variable Results: after 1 month, mean KMW was 7.86±3.22 mm (100%) with no statistically significant intragroup variations no membrane exposures or wound healing complications occurred during the postoperative phase and after one year mean KMW was 5.67±2.12 mm (72.13%). Conclusion: The results of the present pilot study indicate that mucoderm® is suited to augment the periimplant soft tissue and that the results are stable over the assessment period...

Goal: The aim of the study was to histologically determine the role of the repositioned lateral bone window in bone maturation in sinus lift procedure. Furthermore, the osteoconductivity and resorptive behavior of cerabone®, which was used as the sole grafting material, was analyzed. Biopsies were taken ~6 months (group 1) or ~9 months (group 2) after sinus grafting. Main findings: The repositioned bone windows were well integrated and showed bone growing out in direction to the center of the graft, hinting to its osteogenic potential. Newly formed bone was covering most of the surface area of the cerabone® particles, pointing at its excellent osteoconductive potential. A histomorphometric analysis showed no significant differences between both groups regarding new bone formation, connective tissue values or remaining grafting material. TRAP-positive osteoclasts were found on the surface of cerabone® indicating a slow, partial resorption of the bone grafting material. Conclusions: The repositioned bone window showed osteoconductive and limited...

Bone formation rates of both bone grafts...

Effect of deproteinized bovine bone mineral at implant dehiscence defects grafted by the sandwich bone augmentation technique.  Shih-Cheng Wen, Jia-Hui Fu, Hom-Lay Wang. Int J of Periodontics and Restor Dent 2018 Vol.38/1. https://www.ncbi.nlm.nih.gov/pubmed/29240209   Aim of the study was the comparison of the radiological buccal bone thickness at implant dehiscence defects treated by the sandwich technique or a modified version of it. 19 patients with dehiscence defects were included in the study. Defects of the control group were treated with an inner layer of cancellous allograft covered by a layer of cortical allogenic bone and the collprotect® membrane. In the test group the defect was covered with a third layer of bovine bone before placing the collprotect® membrane. While both groups achieved an adequate bone fill of the peri-implant bone defects, significant greater buccal bone gain was found for the modified sandwich technique. The efficiency of collprotect® membrane as barrier to successfully treat dehiscence defects...

Trajkovski et al. Hydrophilicity, Viscoelastic, and Physicochemical Properties Variations in Dental Bone Grafting Substitutes. Materials 2018, 11, 215. https://www.ncbi.nlm.nih.gov/pubmed/29385747 Study aim and design: In this publication the physico-chemical properties of different bone grafting materials were analyzed and compared. The evaluated characteristics comprised viscoelastic and hydrophilic properties, micro structure and chemical composition. Results: - Viscoelastic measurements affirmed that maxresorb® and cerabone® blocks are highly rigid and brittle also following rehydration, while the molecular mobility and therefore elastic properties of maxgraft® indicated to be particularly beneficial. - Analysis with a high speed camera showed that cerabone® and maxresorb® have the highest level of hydrophilicity, while blood uptake of Bio-Oss® and BoneCeramic® were much slower. - Micro computed tomography (µCT) and scanning electron microscopic (SEM) analysis demonstrated the highly porous structure of cerabone®, maxresorb® and maxgraft® and rough surface characteristic of cerabone® and maxresorb®. - Differences in the chemical composition of the bone grafts were demonstrated by infra-red spectroscopy (IR), x-ray powder diffractometry...

Jelusic et al. Monophasic ß-TCP vs. biphasic HA/ß-TCP in two-stage sinus floor augmentation procedures – a prospective randomized clinical trial. Clin. Oral Impl. Res. 0, 2016 / 1–9. https://www.ncbi.nlm.nih.gov/pubmed/27683073 The study compared of monophasic β-TCP (MBS) and biphasic β-TCP (maxresorb®) in maxillary sinus floor elevations using the lateral window technique. Biocompatibility, osteoconductivity and implant stability were analyzed histologically, radiologically and by resonance frequency analysis. Overall 60 patients were treated and 67 sinus lifts were performed. Results: Both monophasic and biphasic materials show good biocompatibility and osteoconductivity with satisfactory support on implant stability. Six months after sinus lift surgery the radiological volume of maxresorb® was significantly more stable than that of ß-TCP (6.66% vs. 22.2%). In addition, resonance frequency analysis endorsed a higher implant stability quotient for maxresorb® after six months....

Lorenz et al. Investigation of peri-implant tissue conditions and peri-implant tissue stability in implants placed with simultaneous augmentation procedure: a 3-year retrospective follow-up analysis of a newly developed bone level implant system. Int J Implant Dent. 2017 Dec; 3: 41. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5585115/ Study aim and design: The study retrospectively analyzed the peri-implant tissue stability after implantation and simultaneous GBR with maxresorb® or pure beta-TCP material. 47 implants in 20 patients were clinically and radiologically evaluated 3 years after loading. Results: The implant survival rate 3 years after loading was 100%. Low median rates for probing depth, bleeding on probing, no osseous peri-implant defects and mean bone loss of 0.55 mm could be recorded. The authors concluded that implants placed in combination with a GBR procedure can achieve long-term stable functionally and aesthetically satisfying results....
