Book excerpt: Clinical and radiographic evaluation of Bio-Oss collagen as grafting material in indirect maxillary sinus floor augmentation.Authors:Anoixiadou S., Batas L. Affiliations:Dept. of Preventive Dentistry, Periodontology and Implant Biology, School of Dentistry, Aristotle University of Thessaloniki, Greece.Background The indirect- transalveolar sinus elevation technique using osteotomes, as described by Summers in 1994, has been successfully used for more than 20 years. A variety of grafting materials have been used to elevate the sinus membrane, such as deproteinized bovine bone, allografts, autogenous bone grafts or combinations of grafts. Aim: To evaluate clinically and radiographically, whether the use of Bio-Oss collagen presents advantages over other granular grafting materials during the indirect sinus elevation technique.Materials & Methods: In this case series of 5 patients, Bio -Oss collagen was used during indirect-transalveolar sinus elevation. Bio-Oss collagen is a combination of 90% xenogenic bovine bone with 10% porcine collagen. In all cases there was a 6 to 7mm residual bone height. Radiographs were taken immediate after the sinus elevation and implant placement and at the follow-up examination. Results:The material proved easy to use and exhibited all the required healing potential to ensure positive treatment outcomes. All implants that were places presented primary stability. More than 4 mm bone height gain was noted radiographically. The main advantage of the use of Bio-Oss collagen was the consistency of the material, its radiopacity, and its handling characteristics. The highly purified porcine collagen allowed tailoring of the material to the morphology of the defect which made it ideal for placement in the sinus osteotomy site. Conclusion:Bio-Oss collagen can be successfully used in the transalveolar sinus elevation osteotome technique and exhibits improved material characteristics compared to granular grafts.

Book excerpt: This completely revised and greatly expanded edition offers authoritative recommendations concerning all aspects of sinus bone grafting procedures for rehabilitation of the atrophic maxilla. Written for the uninitiated as well as the experienced clinician, this comprehensive clinical monograph also guides readers through the maze of new materials and techniques that have been introduced to improve upon or even supplant this procedure. It answers questions such as whether autogenous bone is necessary and where best to harvest it; which bone substitutes are most effective in regenerating bone and how safe they are to use; what contraindications exist, and what complications might be expected; what characteristics of size/shape/surface morphology are most important in choosing an implant; and many others. The last section of the book explores the future prospects for genetic engineering and other gene-based therapies that may one day eliminate the need for bone grafting.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Background (500 characters max.)Very few clinical studies have investigated the influence of lateral window dimensions and appearance on the maturation and consolidation of graft in respect of maxillary sinus floor augmentation (MSFA). From a biological aspect, the residual bone wall represents a source of osteoblast cells; Mechanically, it helps the stability of blood clotting and protects the graft from possible mechanical stress. Previous experimental histological studies in animal have justified that bone formation and osteogenic process start from the sinus walls and septa, and then sprout into the elevated space along the implant surface, determining the maturation of central part of graft itself. Hence, we deemed approximate window dimensions and appearance may have an important influence on the maturation and consolidation of graft in the maxillary sinus.Aim/Hypothesis (300 characters max.)There was an improvement of bone reconstruction and implant survival and reduction of bone resorption and surgical complications when adopting a smaller slot-shaped lateral window compared to a conventional oval-shaped lateral window in respect of MSFA.Materials and Methods (1000 characters max.)Of 106 patients enrolled in the study, each underwent MSFA using deproteinized bovine bone mineral (DBBM) based on two different lateral window access flaps to maxillary sinus (Test group: slot-shaped access window; Control group: oval-shaped access window). Bone dimension and graft remodeling were measured at pre-op, immediately after the procedure (baseline), 6-month (T1), 1-year (T2) and 2-year (T3) post-op Cone-beam computed tomograph (CBCT) and panoramic radiographic imaging (OPT). CBCT scan data were analyzed with image processing software to evaluate the volume of grafted material throughout follow-up period. A life-table analysis was used to assess the implant survival. Intra-op and post-op complications were recorded.Results (1000 characters max.)A prominent augmented bone height (ABH) was obtained in both groups (Test group: 10.53u00b12.83 mm, Control group: 9.23u00b13.24 mm) with significant intergroup difference (P=0.001), whereas no significant intergroup difference was found in augmented bone volume (ABV) (P=0.359). Neither any significant intergroup difference emerged in data concerning the cumulative survival rate (CSR) nor the sinus membrane perforation rate. The augmented height loss (u2206 ABH) of Test group was significantly lower than of Control group during the first 6 months (P=0.020) and the second year (P=0.037). Furthermore, both ABH and ABV resorption rate of Test group was significantly lower than of Control group during the first 6 months after surgery (P=0.022, P=0.017).Conclusions and Clinical implications (500 characters max.)The slot-shaped lateral technique is a simple and predictable surgical method for MSFA and simultaneous placement of dental implants. The technique facilitated to reduce apical augmented bone resorption during the first 6 months after surgery.

Book excerpt: This valuable book presents clinical experiences and research of bone grafting. Bone grafting is an essential technique practiced by craniofacial, maxillofacial, orthopedic, neuro, reconstructive and oral surgeons. Bone grafting can be used for reconstruction and restoring missing bone in trauma and tumor surgery of the facial bone or in road traffic accidents with multiple injuries and in post-traumatic missile war injuries to the face or limbs. Bone grafts, in the form of Kummoona Chondro-Ossous graft or Costo-Chondral graft, are used for reconstruction of damage TMJ for restoration of growth, function, and repair. Bone grafting is a surgical procedure where the iliac crest or rib or tibia is used to perform grafting. In this book, we examine the experimental studies on rabbits to understand the cellular changes associated with bone grafting. From this, we noticed that mesenchymal stem cells and growth factor are released from platelets and these play an important role in healing the bone graft. We recommend this valuable book to all cranio-maxillofacial, orthopedic, plastic, reconstructive, neuro and oral surgeons and to all postgraduate students studying bone grafting.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Background: Lateral bony window coverage utilizing collagen membranes in maxillary sinus floor augmentation by lateral approach delivers favorable results (Pjetursson et al. 2008). The piezoelectric approach allows for repositioning the sinus bony wall (Choung et al.1997), nevertheless data is scarce on the efficacy compared to collagen membrane coverage. The preliminary clinical results of an ongoing prospective, randomized, controlled clinical, radiographical and histological trial are presented. Aims: To demonstrate the non-inferiority of bony wall repositioning compared to collagen membrane coverage in maxillary sinus flooraugmentation. Primary outcome parameter: Histological evaluation. Secondary outcome parameters: duration of surgery and window preparation, perforations, patient morbidity.Materials and methods: 8 healthy patients with at least one missing maxillary premolar or molar with not more than 5mm bone height below the sinus weretreated at the Department of Periodontology, Semmelweis University, Budapest, Hungary by lateral maxillary sinus flooraugmentation. Patients were randomized in two groups: Test (4 patients): lateral sinus window preparation with a piezoelectric device (NSK Variosurg 3), sinus bony wall repositioning. Control (4 patients) lateral sinus window preparation with rotary burs at 400 rpm, bony window covered by resorbable collagen membrane (Botiss Colprotect). Hard tissue grafting was performed using a particulatexenogenic material (Botiss Cerabone) in both groups. Following parameters were registered: duration of surgery and windowpreparation in minutes; percentage of sinus membrane perforations, postoperative patient complaints subjectively evaluated by visual analogue scale, objectively evaluated by number of non-steroid inflammatory drugs taken.Results: Initial healing was uneventful, primary wound healing occurred in all cases, no postoperative infections were observed. Duration of surgery was 50.5u00b19.6 min in test compared to 56.50u00b114.1 min in control. Duration of window preparation was 5.0u00b10.8 min in test compared to 4.8u00b11.7 min in control. Percentage of sinus membrane perforations was 50% in test compared to 50% in control. Postoperative patient complaints subjectively evaluated by visual analogue scale was 24.5u00b130.7 in test compared to 42.3u00b125.6 in control on the day of surgery, 13.5u00b121.4 in test compared to 30.5u00b125.1 in control 1 day postoperatively, 12.5u00b117.7 in test compared to 12.5u00b13.5 in control 2 days postoperatively. Postoperative patient complaints objectively evaluated by number of non-steroid inflammatory drugs taken was 1.5u00b10.6 in test compared to 2u00b10 in control on the day of surgery, 1u00b11.2 in test compared to 0.75u00b10.5 in control 1 day postoperatively, 0u00b10 in test compared to 0.5u00b10.7 in control 2 days postoperatively.Conclusions: According to the preliminary clinical results of the ongoing prospective, randomized, controlled clinical, radiographical and histological trial, duration of surgery, duration of window preparation, percentage of sinus membrane perforations were comparable in test and control. Subjective and objective postoperative complaint evaluation showed more favorable outcomes in the test group, indicating less patient morbidity following piezoelectric sinus window preparation and bony wall repositioning.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: BackgroundHard and soft tissue deficiencies after tooth extraction with poor prognosis may cause functional and aesthetic problems especially inthe anterior maxillary region. Various guided bone regeneration (GBR) techniques are used in order to regain adequate tissue amountfor implant treatment. Combined use of growth factors derived from human blood with grafting materials have been widely used andseen as a predictable treatment modality.Aim/HypothesisThe aim of this two case reports was to evaluate the effects of horizontovertical ridge augmentation on bone gain with combined useof xenograft bone material, Ti-Reinforced non-resorbable PTFE membrane, and CGF prior to implant placement and implant survivalrates.Materials and MethodsA 37-year-old female and a 57-year-old male patient registered with complaints of acute pain and mobility of maxillary lateral teeth.After the clinical and radiographic examination, the extraction of the tooth was planned. The extractions were made non-traumaticallywith periotome and extraction sockets were filled with CGF to enhance the wound healing. 4 weeks after extraction, flap surgery wasperformed for augmentation. The defect was grafted with xenograft bone material (Bio-Oss Collagen, Geistlich) and Ti-ReinforcedPTFE membrane (NeoGen) was fixated with titanium screws. Double layers of CGF were used over the membrane in order to obtainsoft tissue closure. Antibiotic therapy was prescribed for infection control. After the healing period of 6 months, re-entry was made andnon-resorbable membranes were removed before the implant placements. Prosthetic loading was performed after 3 months ofosseointegration period. Recalls were scheduled at 1, 3, 6, 12, and 24 months following.ResultsNo signs of inflammation or infection was observed post-surgically and at follow-up sessions. After the removal of Ti-Reinforced PTFEmembrane, horizontovertical bone gain was observed with CBCT evaluation and clinically. Healing was uneventful without anycomplications after the implant surgery and the implants were in good terms of success rate. The survival rates of implants are both%100 two years after implant placement. Combined use of grafting materials, PTFE membrane, and CGF obtained an adequate boneformation at horizontovertical bone defect sites.Conclusions and Clinical ImplicationsCombined use of xenograft bone substitute, PTFE membrane, and CGF may be an effective treatment modality to regenerate boneformation for horizontovertical bone defect cases prior to implant placement and can improve the implant success and survival rates.The present positive outcomes of these two cases can be considered promising but must be confirmed by long term controlledstudies with larger sample of patients.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The maxillary sinus floor augmentation was performed through lateral approach or transcrestal approach according to residual bone height(RBH). Xenogenic graft(XG), allogenic graft(AG) and alloplastic graft(AP) are commonly used as a bone graft materials. The aim of this study is to investigate radiographic and histomorphometric evaluation after sinus floor augmentation which were performed using anorganic bovine bone(ABB), minenalized cancellous bone allograft(MCBA) and mixed allogenic bone. A total of 47 patients who had RBH lower than 5mm below the maxillary sinus were included this study. ABB, MCBA and mixed allogenic graft(cortical FDBA 50% : cancellous FDBA 50%) were used for procedure. After approximately 6 months, amount of augmented bone height(ABH) and shrinkage of ABH between baseline and 6 months were evaluated by radiographic analysis. In the radiographic examination, amount of augmented bone height(ABH) of ABB, MCBA and mixed allogenic graft was verified. Histomorphometric analysis of bone core biopsies (2mm diameter ) was performed to evaluate the proportion of newly formed bone(NFB), residual graft(RG) and connective tissue(CT). In the histomorphometric examination, there were no significant differences in NFB between ABB and MCBA or mixed allogenic graft (P>0.05). However, NFB of MCBA was significantly greater than mixed allogenic graft (P

Available in PDF, EPUB and Kindle. Book excerpt: Background: Bone grafting materials are widely applied for maxillary sinus augmentation nowadays. However, it is still controversy regarding what grafting material is the most suitable.Aim: To compare the potential of platelet-rich fibrin (PRF) and deproteinized bovine bone mineral (Bio-Oss) in augmenting bone volume after maxillary sinus lift with simultaneous implant placement.Material and Methods: 37 patients with a total of 40 sites of maxillary sinus lift surgery were included in this study. The 40 sites were randomly divided into two groups, the PRF group and the Bio-Oss group. All sites underwent transalveolar maxillary sinus lift using a CAS kit. PRF was placed into the elevated sinus cavity in the PRF group. while Bio-Oss was placed in the Bio-Oss group. Dental implants were installed simutaneously. Cone beam computed tomography (CBCT) scan was performed preoperatively, immediately after surgery and 6 months after surgery to measure Schneiderian membrane thickness (SMT) , residual bone height (RBH), sinus width (SW), implant protrusion (IP), the height of sinus lift and intra-sinus bone gain. The integrity of Schneiderian membrane was checked by CBCT.Results: In the control group, length and diameter of implants were 10u00b10mm and 4.57u00b10.31mm, respectively, and the corresponding values in thePRF group were 10u00b11.19 mm and 4.59u00b10.39 mm, respectively. In the control group, Schneiderian membrane thickness, sinus width and residual bone height were 1.02u00b11.01 mmuff0c13.40u00b12.38 mm and 5.83u00b11.69 mm, respectively, and the corresponding values in the PRF group were 2.52u00b13.49 mm, 13.51u00b12.99 mm and 6.69u00b11.42 mm, respectively. In the control group, implant protrusions, the height of the maxillary sinus lift and bone gain were 3.44u00b10.787mm, 7.56u00b13.37mm and 4.65u00b12.65mmuff0crespectively, and the corresponding values in the PRF group were 3.44u00b10.787mm,7.56u00b13.37mm and 4.65u00b12.65mmuff0crespectively. No significant difference was detected between the two groups for all the tested parameters. Statistical analysis showed that bone gain was related to the height of sinus elevation, but not strongly related to age, SMT, sinus width (SW), RBH and implant protrusion (IP).Conclusion and Clinical implications: Both materials were beneficial for new bone formation after maxillary sinus elevation and the higher the maxillary sinus lifted, the more bone volume was gained.

This book was released on 2020 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Objectives: To study the effect of the recombinant human bone morphogenetic protein-2 (rhBMP-2) on sinus volumetric and histometric changes after sinus floor augmentation compared to a conventional approach utilizing other bone grafting materials, such as autografts, allografts, and xenografts. Materials and methods: A search of 3 electronic databases, including PubMed/MEDLINE, EMBASE, Cochran Library Central, and a hand search for peer- reviewed journal relevant articles were performed. Relevant articles that were published between the years of 1999-2019 were included in the search. Human clinical trials with data on comparison of sinus volumetric and histometric outcomes with and without the use of rhBMP-2 in sinus grafting procedures, with 10 or more augmentation sites in each study group, and with a follow-up period of at least 3 months, were included. Variables such as the primary outcome (vertical bone level gain) and the secondary outcome (including implant survival rate, bone density, and the histological parametrics) that were recorded for each study was compared and analyzed. Results: Seven randomized controlled trials (RCTs) were included. The two approaches (conventional bone grafting compared to bone morphogenic proteins (BMPs)) demonstrated comparable effectiveness for both clinical and histomorphometric measures. Conclusions: This systematic review revealed that the use of rhBMP-2 in maxillary sinus floor augmentation achieved similar clinical and histometric outcomes when compared to conventional sinus grafting procedures after a healing period of at least 3 months or longer. Currently, the concentration and amount of rhBMP-2 utilized to gain bone formation in maxillary sinus floor augmentation remains unclear and will need further clinical studies completed.
