Book excerpt: Placement of endosseous implants in the posterior maxilla is often difficult because of a lack of supporting bone. Sinus augmentation procedures have therefore been extensively used for the treatment of the edentulous atrophic posterior maxilla prior to implant placement. This book describes in detail the most widely used sinus grafting techniques as well as some innovative variations, with full coverage of both lateral and crestal approaches. A key aim is to assist the practitioner in selecting the appropriate sinus grafting technique based on the evaluation of a number of parameters that are described in detail and codified in a simple and practical way. Up-to-date information is also provided on grafting materials and on potential complications of sinus augmentation procedures and their treatment.

Download or read book Evaluation of the Indirect Sinus Elevation Technique Using a Sinus Endoscope on Fresh Cadavers written by Monte Edward Masonbrink and published by . This book was released on 2006 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The osteotome sinus elevation technique is a widely utilized method of gaining additional bone height in the posterior maxilla. Indications for this technique are limited to those situations in which there is enough residual alveolar bone height to provide implant stability. As reported in the literature, the technique can accomplish 3.5 to 5mm of elevation and is ideal for 5mm or more residual ridge. The purpose of this cadaveric study was to evaluate the sinus membrane endoscopically during the elevation process and quantify the amount of elevation without rupture. Additionally, the bone height as measured on a calibrated dental panorex was correlated with the actual measured bone height. The relationship between residual bone height and the amount of elevation was also analyzed. A total of 10 fresh cadaver heads were obtained, and the osteotome sinus lift technique performed once on each side under endoscopic control. A calibrated panoramic radiograph was compared to the actual clinical bone height using a regression analysis. The mean radiographic height was 7.1 +1- 4.2mm, and the mean clinical bone height was 6.0 +1- 3.4mm. We were able to predict the clinical height from the panorex as shown by the regression analysis (R2 = 0.54). The mean sinus floor elevation for the sample was 8.5 +1- 3.5mm (N=19). The regression analysis demonstrated no relation between the height of the residual bone and the amount of sinus floor elevation (R2 = 0.004 1). The results suggest that the amount of elevation from the osteotome technique may be greater than previously thought. In 14 of the 19 (74%) sinus elevations performed, the elevation was enough to accommodate a 13mm implant. Further clinical trials would be necessary to better define the limits of the osteotome technique.

Available in PDF, EPUB and Kindle. Book excerpt: BackgroundExtraction of posterior maxillary teeth can result in severe bone resorption, which may preclude the placement of dental implants. Traditionally, techniques involving bone graft material are used to overcome this loss of bone volume. Less invasive and more cost-effective graft-less procedures have also been shown to be clinically effective. Here, we evaluated a new implant design in graft-less sinus floor elevation using both lateral and crestal approaches. AimIn this open prospective clinical study, we investigated the clinical performance of a new reverse spiral flute implant design (Nobel Biocare AB, Gothenburg, Sweden) used in lateral and crestal graft-less sinus floor elevation protocols. One-year outcomes are presented. Materials and MethodsPatients seeking implant-supported restoration of the posterior maxilla and requiring sinus floor augmentation with a residual bone height less than 8 mm at implant site were included. Implants were placed using either a lateral or crestal graft-less sinus floor elevation protocol. Crestal at residual bone height of 6 to 8 mm, Lateral in bone heights less than 6 mm. The new implant design features an anodized surface, a rounded apex and a sharp cutting flute oriented in the opposite direction of the implant threads with the aim to deliver bone chips into the sinus cavity to facilitate new bone formation. Implants were placed in healed sites and loaded with screw-retained temporary fixed restorations after 6 months of submerged healing. Final restorations were placed after 2 months of function. Clinical and radiographic data including implant and patient level cumulative survival rate (CSR), implant stability quotient (ISQ), and implant complications were assessed at regular intervals. Results132 implants were placed in 60 patients of both sexes with a mean age of 58 years. In 40 patients, 98 were placed with the lateral technique and in 20 patients, 34 implants with the crestal one. At 1 year follow up 3 implant failed, 2 in the lateral and 1 in the crestal group. CSR was 97.7% at implant level and 95.0% at patient level.u2028All surviving implants were stable at the 1year follow up (n=129). For the resonance frequency analysis, mean ISQ values were 66.4, 74.5 and 79.1 for the lateral approach and 75.3, 80.7, and 84.0 for the crestal approach at implant placement, at 6- and 8-month follow-ups, respectively. The sinus membrane was accidentally perforated during the sinus elevation procedure in 12 patients. In another 6 patients the perforation was on purpose due to simultaneously removal of intra sinusal cysts. No perforations were caused from implant insertion. Radiographic analysis of 3D bone remodeling is currently ongoing and will be reported at the time of presentation. ConclusionsIn situations of severe bone resorption in a pneumatized maxilla, the reverse spiral flute implant has excellent stability, indicated by increasing ISQ values at subsequent follow-ups, and good survival rates after 1 year of function when placed using a graft-less lateral or crestal sinus floor elevation protocol.

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.

Download or read book Evaluation of New Bone Formation After Osteotome Sinus Floor Elevation and Simultaneous Implant Placement Without Grafting by Two Radiographic Methods written by Guofen Lin and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: After tooth loss, alveolar bone atrophy and pneumatization of the maxillary sinus occur. It is difficult for implant placement to posterior maxilla because of the reduced residual bone height (RBH) available. Osteotome sinus floor elevation (OSFE) is a reliable technique and produced satisfied results. Compared with oral panoramic radiograph (OPG), the application of cone beam computed tomography (CBCT) that provides clinically valuable information is considered to be more accurate assessment. The purpose of this study was to compare radiographically the variances of measurements on OPG and CBCT, and to evaluate the effects of endo-sinus new bone formation after OSFE without grafting in a short time. Simultaneously, to analysis the potential related factors of endo-sinus bone gain (ESBG).

Book excerpt: This comprehensive guide to short implants will take the reader through their research and development, explain the clinical indications, evaluate the outcomes achieved with various implants, and explore restorative and laboratory considerations. Short implants have steadily gained greater market share in the last decade as practitioners sought alternatives to traditional length implants in order to avoid grafting procedures. Current manufacturers offer a variety of implant lengths and widths, allowing surgeons and restorative dentists the ability to select the best implant for each clinical circumstance. Cutting edge information is provided on the research and clinical results achieved utilizing a range of implants, specifically those developed by Nobel Biocare, Straumann, Jack Hahn, and Bicon. Readers will also find an extensive description of the role of ultra-short implants involving reconstruction in both cleft patients and cancer patients who have lost portions of their mandible and/or maxilla. This book is a must-have for those interested in learning how the use of short and ultra-short implants offers both surgeons and restorative dentists an opportunity to stand out from those that use only the traditional length implants.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Background Maxillary sinus floor elevation with a lateral approach (LSFE) represents the most predictable surgical procedure to vertically enhance the available bone in the edentulous posterior maxilla. Intra-operative complications and post-operative patient morbidity are the main issues of concern for patients and clinicians. Aim/HypothesisThe aim of this study is to evaluate the patient-reported outcomes and complication rates in 50 patients after augmentation of maxillary sinus.Material and Methods50 consecutive patients with residual bone height less than 5 mm were treated between 2018 and 2019 in 3 different private centers. All patient underwent to LSFE procedure (T0) before implant placement (T1) and restoration (T2) using a bovine bone graft (Bio-Ossu00ae; Geistlich Pharma, AG, Wolhusen, Switzerland).Patient-reported outcomes were assessed using a 100-mm visual analog scale (VAS) to evaluate the post-operative pain experienced in the first week following surgery and visual rating scales (VRS) to evaluate discomfort level, swelling level, and willingness to undergo the same surgery. Analgesics intake, onset and duration of swelling and ecchymosis were also evaluated. Finally, all complications were recorded and divided into: surgical complications (venous or arterial bleeding, sinusal membrane perforation, or buccal flap laceration) and healing complications (wound dehiscence, infection / fistula, or sinusitis).ResultsAll 50 patients were completely evaluated according to the study protocol. Pain level showed moderate values in the first (median: 50; IR: 60-46.2) and second day (median: 50; IR: 60-40) with a tendency to decrease over the third (median: 30; IR: 50-20) and fourth day (median: 14; IR: 28.25u20137.75), showing median values of 0 from the fifth day. Average analgesics intake during the week following the surgery was 4.1u00b12.8. Discomfort level was low (median: 1; IR: 1-0), while willingness to undergo the same surgery was very high (98% of patients; median: 0; IR: 0-0). Swelling and ecchymosis were experienced by 100% and 56% of patients respectively with a mean duration of 4u00b10.9 and 4.2u00b10.9 days respectively. Surgical complications included only 3 membrane perforations (6%), while no healing complications were observed (0%). Conclusion and Clinical implicationsThis study confirmed that LSFE is a safe and predictable procedure because of moderate patient morbidity and very low complication rates. High level of willingness to undergo the same surgery should encourage clinicians to choose LSFE for bone augmentation in posterior maxilla.

Download or read book Slot Versus Round shaped Lateral Windows for Maxillary Sinus Floor Augmentation a 2 year Clinical and Radiographic Study written by Lu Wei and published by . 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.

Download or read book Lateral Sinus Floor Elevation and Simultaneous Implants Placement in One Surgical Step written by and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Background In posterior edentulous maxilla, in cases of residual bone height (RBH) less than 4mm the lateral sinus floor elevation with thedelayed implants placement is recommended. However, even in such situations, it is often possible to place implants. It is necessaryto appreciate the possibility of lateral sinus floor elevation with simultaneous implants placement using non-submerged approach. Aim/Hypothesis The evaluation of implants integration in cases of non-submerged approach simultaneously with lateral sinus floor elevation inresidual bone height less than 4 mm.Materials and Methods The study was axed on 7 partially edentulous patients (43.24 years, standard error of 3.9 years) who received 16 two-piece dentalimplants (extended platform, conical connection, 3.6 - 4 mm diameter and 10-12 mm length) inserted in posterior sides of the maxillawith lateral-sinus floor elevation (grafted with collagen and hydroxyapatite sponges). The residual bone height was 3.43 mm(Standard error of 0.08 mm). Due to the insertion torque higher than 15-20 Ncm, the healing abutments (3 to 5 mm height) wereconnected before suturing. The radiographic examinations were performed before, after the surgery and at the end of healing period.After 6 months, the prosthetic treatment has been initiated. According to the panoramic x-rays, implants sides were divided intoanterior and posterior ones. The secondary stability, endo- sinus bone gain as well as the marginal bone loss were appreciated.Statistical analysis was made by calculating mean values and standard errors (SE).ResultsAll implants successfully integrated and the healing period was uneventful. The length of implants protruded into sinus were 8.12(SE=0.23)mm and 8.15(SE=0.17)mm from mesial and distal aspects. After healing, the endo-sinus bone gain was 7.92(SE=0.23)mmand 7.89 (SE=0.19)mm respectively. The crestal bone loss consisted: 0,41 (SE=0.09)mm from mesial and 0.37 (SE=0.08)mm fromdistal aspects. The secondary stability (Periotest values) were -4.62 (SE=0.256). Peri-implant mucosa showed signs of bleeding onlyaround 2 implants (type 2 by Mombelli) due to plaque accumulation on the healing abutments. Radiographically, the new formed bonehad the same opacity and structure as the native bone.Conclusions and Clinical Implications In case of residual bone height less than 4 mm, itu2019s possible to perform the lateral sinus floor elevation and implants placement usingnon-submerged approach (one-step surgery) if the insertion torque is higher than 15-20 Ncm. This technique is advantageous due toreduced terms of healing, less number of surgeries and a mature biological width at the end of healing. According to progressiveloading theory, the presence of healing caps may lead to a better quality bone formation during healing.

Download or read book Quantitative Evaluation of Sinus Floor Elevation Using the Plate Shaped Bone Substitute written by and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Sinus floor elevation is often applied to the molar region of the atrophic maxilla to increase bone mass between the alveolar crest andthe sinus floor. Although autogenous bone graft is, so far, gold standard, limitations of donor site bone volume and post-operativemorbidity could be disadvantages. Thus, artificially synthesized bone substitutes, hydroxyapatite (HA) and tricalcium-phosphate(TCP), might be advantageous useful materials compared to the autogenous bone.We have developed a novel technique of the sinus floor elevation using plate-shaped beta-TCP . In this study, changes of graftedbone volume were quantitatively evaluated with cone-beam computed tomography (CBCT) and image analyzing software before and1, 2, and 5 years after the surgery. Ten cases were recruited in this study. The bony windows were prepared on the lateral wall of the sinus and the sinus membrane wascarefully removed and elevated. Subsequently, the TCP plate was inserted and supported with dental implants or micro-screws.Then, CBCT scan was performed to estimate temporal changes of the bone volume before surgery and at the time points of one, two,and five years after the surgery. Digital Imaging and Communication in Medicine (DICOM) files of CBCT were converted intoStereolithography (STL) files, using dedicated image analysis software for bone volume measurement and superimposing image datawith the best fit method. The difference of the image data representing the bone volume before and after the surgery was amalyzedthree-dimensionally, and the rate of change was calculated. This clinical research was approved by Ethics Committee, School ofDentistry, Iwate Medical University, and the patient's consent was also obtained. Ten cases of the sinus floor elevation with plate-shaped beta-TCPs have been performed since 2011. This study consisted of threemen and seven women. The average age of all the patients was 53.3 years old. Bone volume decreased slightly until 2 years after thesurgery and then increased again until 5 years after the surgery. There had no complications concerning the abnormalities of themaxillary sinus since the postoperative to the present, and it passed well. In most cases, newly formed bone in the sinus wasobserved on X-ray photos 6 month after the operation. The good stability of the dental implant, at the second stage surgery, wasconfirmed. TCP plates remained in the same position and achieved the secure space making for long time. Panoramic X-ray andX-ray CT analyses revealed that TCP-plates were resorbed in 5 years post operation in most cases. The results of our study demonstrated that it is possible to evaluate the change of bone volume of the sinus floor elevationquantitatively using the data of the STL form which converted DICOM. In this clinical trial, a new bone formation was observed in theempty space between the TCP plate and the original sinus floor. TCP is a bone-conductive material and might have accelerated boneformation. This newly established method for sinus floor elevation could bring better long-term prognosis.
