Download or read book Short Implants written by Boyd J. Tomasetti and published by Springer Nature. This book was released on 2020-07-07 with total page 334 pages. Available in PDF, EPUB and Kindle. 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 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: AIM: To compare, clinically and radiographically, short dental implants (6 mm) to long implants (11-15 mm) placed with sinus grafting. METHODS: Participants with 5-7 mm of bone height in the posterior maxilla were randomly allocated to receive short implants (GS) or long implants with sinus grafting (GG). Implants were loaded with single crowns 6 months after placement (PR). Patients were re-evaluated up tp 60 months after loading (FU-5 years). Outcome variables included: marginal bone level alteration (MBL), implant success and survival rate, periodontal probing depth (PPD), bleeding on probing (BoP), plaque control record (PCR) and crown-to-implant ratios (C/I). Statistical analysis was performed using non-parametric tests. RESULTS: 13 patients, 15 implants were re-evaluated at FU-5 years. Intergroup comparison reported no statistical differences in marginal bone loss from baseline to 5 years (GS,-0.33 ± 0.29/GG, +0.32 ± 0.9, p=0.233). No statistical differences were found for PD, BoP and PCR. CONCLUSION: Both treatment modality provided similar outcomes.

Download or read book Early Clinical Outcomes of a New Implant Design Used in Graft less Sinus Floor Augmentation written by and published by . This book was released on 2017 with total page pages. 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: 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.

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 2013 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: Objective: To compare the stability of short implants placed in the posterior maxilla and mandible within a 4-month healing period.Material and methods: A total of 24 patients who were partially edentulous in the posterior were enrolled in the study. Thirty short implants (4.2 mm in diameter and 7.5 mm in length) with rough surface were placed with 2-stage surgical approach (15 implants each in maxilla and mandible). Resonance frequency analysis (RFA) was used to measure implant stability at time of surgical placement, at 2 months, at 3 months, and at 4 months after surgical placement. Implant stability quotient (ISQ) values of maxillary and mandibular implants were compared using Mann Whitney test and Wilcoxon Signed Ranks test.Results: Within the 4-month healing period, the ISQ values increased gradually in both maxillary and mandibular implants. The mean ISQ values of implants in the mandible were significantly greater than those in the maxilla at every respective length of healing time. The success of short implants in this study was 96.7%. Conclusions: Short implants with rough surface in the posterior maxilla had less stability than those in the posterior mandible during the 4-month healing period. Our study indicated that short implants with rough surfaces can gain a high degree of osseointegration within 2 months in the mandible and within 3 months in the maxilla if good stability was achieved at implant placement.

Available in PDF, EPUB and Kindle. Book excerpt: Maxillary sinus elevation, followed by placement of a wide variety of grafting materials, has been the generally accepted surgical protocol for the development of bone in the sinus cavity. Over the years, various techniques have been proposed for maxillary sinus elevation, which differ in surgical approach, bone graft materials, and advanced technology application for hard tissue and soft tissue management. Dr. Kao and a team of experts begin by discussing anatomy, radiographic image applications and limitations, and then provide step-by-step clinical procedures for the lateral window technique, including piezosurgery, and the trans-alveolar methods, including balloon and controlled hydostatic sinus elevation. Also included are chapters on post-operative care and complication management.

This book was released on 2015-11-05 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: The posterior maxilla presents several challenges to the implantologist of which pneumatisation of the maxillary sinus is one such problem. The management of this problem in the most atraumatic way is important for long-term success of implants placed in this region. Implant dentistry has become an excellent treatment modality since its inception into the modern era of dentistry. Surgical technique that allowed the elevation of the sinus membrane and implant placement in the same surgical appointment has become routine procedure since last decade. The procedure may be one stage (i.e. placement of implant and graft material in one surgical procedure) or two-stage (i.e. implants are placed after few months of graft maturation). Sinus lift surgery can be done using different surgical techniques, viz. crestal approach (Osteotome technique, Cosci technique) lateral window technique, newer techniques such as Balloon Sinus lift, Sinus lifting by piezosurgery, Hydraulic sinus lift, etc. This book covers a detail description of all these techniques and materials and can surely be a handy for dental surgeons in general and the implantologist in particular.
Download or read book Comparative Study of Immediate Loading on Short Dental Implants and Conventional Dental Implants in the Posterior Mandible A Randomized Clinical Trial Four Months Post loading written by Khongkhunthian Pathawee and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Immediate dental implant placement and loading treatment protocol has been investigated with the promising clinical results. However, the use of short implant in this treatment option has not been performed. The purpose of the study was to compare the clinical outcomes and survival rates of immediately-loaded short implants and conventional length dental implants (Pw Plus dental implant system, Thailand) in replacing mandibular molar teeth.Materials and methodsThe clinical study was approved by the Human Experimentation Committee. Fifty implants in 46 patients were included in the study. Twenty five short dental implants (6 mm.) and 25 conventional dental implants (10 mm.) were randomly placed as single tooth replacements in the edentulous molar areas of the mandibles. Provisional, CAD-CAM, ceramic block (Shofu HC) crowns were cemented to the abutments of the implants, and immediately loaded. The clinical parameters, such as insertion torque (IT), resonance frequency analysis (RFA), marginal bone level changes, and complications, were recorded and statistically analysed.ResultsTwo short implants and two conventional implants were excluded from the study due to insufficient insertion torque (less than 35 Ncm). Two short implants disintegrated, and one conventional implant failed. The accumulate survival rate of short implants was 91.30%, compared to 95.65% for conventional implants. However, there was no significant difference between the two implant types (P (Fisheru2019s exact) = 1.00). Only minor complications were found (three provisional crown fractures with short implants and two with conventional implants).The differences in IT among the two implant types were not significant (P =.264). There was no significant difference in ISQ value for short or conventional implants between baseline (short: 73.86 u00b1 2.38 mm, conventional: 75.05 u00b1 3.26mm, P=.088) and four months after loading (short: 72.37 u00b1 1.35 mm, conventional: 72.89 u00b1 1.87 mm, P=.165). The mean change in marginal bone level four months post-loading was 0.24 u00b1 0.29 mm for short implants and 0.26 u00b1 0.29 mm for conventional implants ; there was no statistical difference between the two implant types.ConclusionsWithin the limitations of this study, the findings seem to confirm that the immediate loading of short implants is a viable option, comparable to conventional length implants in terms of implant survival, marginal bone loss and ISQ value.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduction: Oral rehabilitation in the posterior maxilla, after long period of edentulism, may become a challenge. Most of the times the remaining bone volume might become incompatible with an implant-supported rehabilitation. Maxillary sinus augmentation with a graft material is considered one of the most predictable procedures, to restore adequate bone volume for implant placement.Design: Retrospective cohort.Aim: To evaluate the survival rate of implants placed in the posterior maxilla, using the lateral antrostomy technique, at the University of Lisbon, College of Dentistry u2013 Implantology Program.Materials and Methods: Evaluation of dental records and x-rays was performed to assess implant survival. Smoking status, maxillary vs. mandible rehabilitation and diabetes were recorded and considered as covariates. Follow up periods ranged from ?1 to 6? years with appointments at 6 months intervals. Survival analysis with Cox Regression Model, Chi-square, relative risk, absolute risk increase and number needed to harm were used as appropriated, confidence level was set at 95%. Alpha was set at 0,05.Results: This study included 52 implants from 25 patients with age ranging from 32-85 years old. Of the 25 patients: 8 were male and 17 female; 6 were smokers and 19 non-smokers; 1 patient was diabetic. The follow-up period for this study was between 9-75 months. The survival rate of this preliminary retrospective study was 100%.Conclusion: Lateral antorstomy is a predictable technique for the placement of implants in posterior edentate maxilla where bone volume is short. Even though the sample is small, this study presents an implant survival rate similar to that described in the literature.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Purpose: To evaluate the clinical and radiographic outcomes of a one-stage crestal sinus elevation procedure using a self-tapping endosseous implant system (iRaise, Maxillent, Herzliya, Israel) developed for sinus augmentation, 1 year after loading.Materials and Methods: Patients needing restoration in the posterior maxilla with a residual alveolar crest of 3 to 8 mm in height and 5 mm in width distal to the canine as measured on CBCT scan were treated using the iRaise sinus lift system. Outcome measures were: implant and prosthetic failures, any complications, increased bone height (iBH), marginal bone loss (MBL), implant stability quotient (ISQ), radiographic tissue remodelling patterns using the sinus grafting remodelling index (SGRI), volumetric measurements of sinus graft, patient self-reported post-surgical swelling, consumption of pain medication and histological analysis.Results: A total of 30 consecutive participants with a mean age of 54.2 u00b1 9.4 years underwent a transcrestal elevation of the sinus membrane, insertion of bone graft, and implant placement. A total of 50 implants were placed (30 iRaise system implants and 20 adjunctive iSure implants, Maxillent). The mean follow-up was 15.8 u00b1 2.1 months after implant loading. One patient dropped out at the 1-year after loading follow-up examination. No implants and no prostheses failed during the entire follow-up. One patient experienced a small membrane tear. Before implant insertion, the mean residual alveolar ridge height was 4.64 u00b1 0.86 mm (range: 3.4u20136.4 mm; 95% CI: 4.39u20135.01 mm). One year after loading, the bone height was 16.86 u00b1 3.13 mm (95% CI 15.83u201318.07 mm). At the 1-year after loading follow-up, the mean MBL was 0.19 u00b1 1.05 mm (95% CI 0.02u20130.78 mm). The mean ISQ at implant placement was 65.2 u00b1 5.4 (95% CI 63.6u201367.4) and increased during the healing period reaching the mean value of 73.6 u00b1 3.7 (95% CI 73.1u201375.9; range 62u201379). The difference was statistically signi cant (8.4 u00b1 5.3; 95% CI 5.9u201339.7; P = 0.0000). One year after loading, SGRI score was evaluated in 23 implants. Overall, the mean SGRI value was 2.29 u00b1 2.41 mm (95% CI 1.22u20132.98 mm). Bone volume at implant placement was 2.41 u00b1 0.25 CC (95% CI 2.22u20132.48 CC). During the 6-month, submerged healing period, a slight bone contraction of 11.3% were observed. (2.13 u00b1 0.24 CC;95% CI 2.02u20132.26; difference = 0.27 u00b1 0.25 CC; 95% CI 0.10u20130.36; P = 0.0011). At the rst year post-loading period, the bone graft remained stable (2.11 u00b1 0.22 CC; 95% CI 2.02u20132.24). The difference was not statistically signi cant (0.02 u00b1 0.07 CC; 95% CI 0.01u20130.04; P = 0.2166). From the patientu2019s point of view, the mean pain value was 0.52 u00b1 0.74 (range 0u20133); mean swelling value was 0.27 u00b1 0.52 (range 0u20132); and the mean consumption of analgesic was 0.87 u00b1 4.94 tablets (range 0u20134) 3 days after surgery. Morphological and histomorphometric analyses showed that all the samples had a normal structure without inflammatory in ltrate, six months after healing. The following fractions (%) were found: bone (immature bone + mature bone): 44.07 u00b1 4.91; residual biomaterial: 23.98 u00b1 2.64; medullary spaces: 31.95 u00b1 3.16.Conclusions: Sinus oor augmentation can be successfully accomplished with a transcrestal approach using a dedicated implant system. A physiologic contraction of 11.3% of the original volume of the bone graft was experienced during the rst 6 months of healing; afterwards, no additional graft volume reduction was observed. Long-term clinical studies are needed to con rm these preliminary results.
Download or read book Maxillary Sinus Augmentation written by N. Mani Sundar and published by LAP Lambert Academic Publishing. This book was released on 2012 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: Maxillary teeth are among the teeth with the highest incidence of periodontal bone loss and tooth loss. Following the removal of posterior dentition, a combination of horizontal and vertical alveolar bone resorption with maxillary sinus expansion frequently results in lack of bone. This results in the wide spread treatment need to restore masticatory function in the posterior maxilla.Since the introduction of sinus graft technique by TANTUM in 19863; BOYNE AND JAMES in 19804; various types of graft materials, implants and procedural modifications have been proposed to improve the efficacy of the therapy. Maxillary SINUS grafting has become a routine treatment over the last ten years. It allows the placement of dental implants using simultaneous or staged procedures in sites in posterior maxilla that were previously considered unsuitable for implant placement because of insufficient bone volume The procedure is referred to as one stage when the implants and graft are placed simultaneously; while in two stage procedure, implantplacement is delayed for several months to allow for graft maturation.
