Dhanrajani, BDS, MDS, MSc.Implantologist, Riyadh Dental Center, Riyadh, Kingdom of Saudi Arabia.A case is reported of an extensive ossifying fibroma involving the mandible and its successful rehabilitation by using an osseointegrated implant. The lesion was enucleated under general anesthesia along with involved teeth Nos. 35, 36, 37, and 38. Regular radiographic follow-up showed complete bone healing within the period of two years. A free-end saddle removable partial denture was avoided by the appropriate use of root-form implants. www@implantoloji.info (JDI editor) Tue, 07 Apr 2009 01:00:00 -0400 http://www.implantoloji.info/articles/23/1/The-Adaptation-of-Implant-Supported-Superstructures-to-the-Alveolar-Crest-A-Follow-Up-of-49-Cases/Page1.html Stefan Ahren, DDSPrivate Practice, VÃnersborg, Sweden.Karl-Erik Kahnberg, DDS, PhDDepartment of Oral and Maxillofacial Surgery, Faculty of Odontology, GÃteborg University, GÃteborg, Sweden.A prospective clinical and radiographic study has been carried out in 49 patients with a total of 252 implants. In a mixture of 17 edentulous mandibles, 20 edentulous maxillas, nine partial edentulous cases, and three single-tooth cases, prosthetic treatments were aimed at getting as close an adaptation as possible between gingival tissues and superstructure. The shortest possible abutments were used, and the implants were surgically positioned subcrestally. The results during a 5-year follow-up showed a success rate of 98.9% for fixtures in the lower jaw and 96.3% for the upper jaw with a total success rate of 97.3%. The marginal bone reduction during five years with closely adapted superstructures was 0.11 mm in the mandible and 1.1 mm in the maxilla. Our results support the use of close gingivally adapted superstructures, although oral hygiene controls and instructions are regularly advisable. www@implantoloji.info (JDI editor) Tue, 07 Apr 2009 01:00:00 -0400 http://www.implantoloji.info/articles/22/1/Complications-After-Maxillary-Sinus-Augmentation-A-Case-Report/Page1.html Mohamed A. Maksoud, DMDPrivate Practice, Jacksonville, Florida, USA.The maxillary sinus grafting procedure has been routinely performed with predictable results. The procedure has proven to be an acceptable modality for bone augmentation to provide a base for endosseous implant placement. Several complications have been documented in the literature. They vary from sinus membrane perforation to formation of a mucocele inside the bony graft mass. This report describes a serious complication after a maxillary sinus augmentation that resulted in obliteration of the sinus. www@implantoloji.info (JDI editor) Fri, 03 Apr 2009 01:00:00 -0400 http://www.implantoloji.info/articles/21/1/Computer-Analysis-of-Titanium-Implants-in-Atrophic-Arch-and-Poor-Quality-Bone-A-Case-Report/Page1.html Rainer Bocklage, DMD, DUIPrivate Practice, Dormagen, Germany.The oral implantologist usually uses a panoramic radiograph for the evaluation of bone tissue around implants. The development of computed tomography combined with computer software has allowed for the bone-to-implant interface to be illustrated in greater detail with cross-sectional and pseudo-color images. An implant patient has titanium fixtures in an atrophic arch and poor quality bone four years after implantation. The implants were loaded with fixed metal/resin restorations seven days after surgery. Integration of the implants and the anatomic structures near the implant sites are described with an imaging technique. www@implantoloji.info (JDI editor) Wed, 01 Apr 2009 01:00:00 -0400 http://www.implantoloji.info/articles/20/1/A-Survey-Of-Clinical-Members-Of-The-Association-Of-Dental-Implantology-in-the-United-Kingdom-Part-II-The-Use-Of-Augmentation-Materials-In-Dental-Implant-Surgery/Page1.html M. P. J. Young, BDSP. Sloan, BDS, PhD, FRCPath, FDSRCS(Eng)A. A. Quayle, LDS, FDSRCS(Eng), PhDD. H. Carter, BSc, MPhil, PhDUnits of Oral Surgery and Oral Pathology, Turner Dental School and Hospital, University of Manchester, Manchester, England, UK.This survey shows that a wide range of materials is used in the United Kingdom for bone augmentation in relation to oral implantology, and it is reassuring that long-term survival rates for implants inserted into sites that have been augmented are high. In the first instance, there is a pressing requirement for a systematic review to be carried out with regard to the efficacy of autogenous bone and DFDB in this context. However, it remains apparent that RCTs (including clinical and histological outcomes) are required to compare the long-term success rates for implants inserted into sites grafted with different augmentation materials. Until the evidence base for augmentation materials in oral implantology is clearly established, the choice of an augmentation material will remain heavily influenced by the training, experience, and preferences of the individual clinician30 and presumably by the effects of marketing by companies that produce augmentation materials. www@implantoloji.info (JDI editor) Sat, 07 Mar 2009 01:00:00 -0500 http://www.implantoloji.info/articles/19/1/Effect-of-Biofluid-Environment-on-the-Dissolution-and-Flexural-Strength-of-Calcium-Phosphate-Bone-Cements/Page1.html SA Bender (BA), Dental student, University of Texas Health Science Center at San Antonio, School of Dentistry, San Antonio, TX, USA.JP Schmitz (DDS, PhD), Associate Professor, Department of Oral and Maxillofacial Surgery, University of Texas Health Science Center at San Antonio, San Antonio, TX, USA.JL Ong (PhD), Associate Professor, Department of Restorative Dentistry, Division of Biomaterials, University of Texas Health Science Center at San Antonio, San Antonio, TX, USA.As observed in this study, there was a continual increase in Ca21 and P51 dissolution detected in all three test media throughout the 21 days. No statistical difference in overall Ca21 release in the three different media was observed. However, the P51 release from Tris solution and fetal bovine serum solution was significantly higher than the P51 release from tissue fluid substitute. In addition, no significant difference in transverse strength was observed for samples immersed in the three solutions during the 21-day period. However, the transverse strength for immersed bars at 37ÂC was statistically greater than the transverse strength for non-immersed bars. Thus, it was concluded from this study that the dissolution of Ca21 from CaP bone cements was independent of the dissolution media, whereas P51 release was dependent on the constituents of the dissolution media. It was also concluded from this study that the transverse strength of the CaP bone cements was not significantly affected by the dissolution process but by the temperature at which the bone cement was exposed. www@implantoloji.info (JDI editor) Thu, 05 Mar 2009 01:00:00 -0500 http://www.implantoloji.info/articles/18/1/Comparison-of-Anorganic-Bovine-Mineral-With-and-Without-Synthetic-Peptide-in-a-Sinus-Elevation/Page1.html Dennis G. Smiler (DDS, MScD)Private practice, Encino, California. USA.The sinus elevation procedure has evolved over the years as one of the most predictable and dependable procedures done to increase the volume of bone allowed for acceptable implant placement. With the introduction of new tissue-engineered bone replacement graft materials, there is an increased confidence in attaining a bone foundation into which implants can be inserted in a shorter period of time. www@implantoloji.info (JDI editor) Tue, 03 Mar 2009 01:00:00 -0500 http://www.implantoloji.info/articles/17/1/Bone-Interface-of-Dental-Implants-Cytologically-Influenced-by-a-Modified-Sandblasted-Surface-A-Preliminary-In-Vitro-Study/Page1.html Dehua Li (MD, DDS, PhD), Associate Professor, Department of Oral and Maxillofacial Surgery, Qindu Stomatological College, Xian, China.Baolin Liu (DM, DDS), Professor and Chairman, Craniofacial Implant Center, Qindu Stomatological College, Xian, China.Junzheng Wu (DM, DDS), Professor and Chairman, Department Of Oral Biology, Qindu Stomatological College, Xian, China.Jianyuan Chen (Technician), Technician, Department Of Oral Biology, Qindu Stomatological College, Xian, China.In this study, a three-dimensional cell culture model was applied to study the biological interaction between bone and implants on the cytological scale. It reveals at this in vitro level that the rough surface created by the modified sandblasting surface treatment can induce a real perpendicularly connecting bone-fiber osseointegration that might favor the interfacial biomechanics of implants and at the same time enhance the functions of osteoblasts. www@implantoloji.info (JDI editor) Tue, 03 Mar 2009 01:00:00 -0500 http://www.implantoloji.info/articles/16/1/Experimental-Study-of-Bone-Response-to-a-New-Surface-Treatment-of-Endosseous-Titanium-Implants/Page1.html Antonio Sanz R., DDSPeriodontist, Adjunct Professor in Oral Implantology, and Director of the Postgrade in Oral Implantology, Odontology Faculty, University of Chile, Santiago, Chile.Alejandro Oyarzun, DDSBiochemical and Oral Biology Unit, Odontology Faculty, University of Chile, Santiago, Chile.Daniel Farias, DDS, Ivan Diaz, DDSSpecialist in oral implantology, Odontology Faculty, Postgraduate School, University of Chile, Santiago, Chile.This experimental research shows the biocompatibility of Restore RBM implants (Lifecore Biomedical) at the light microscopy level. It leads to the proposal that a new process be used to create a textured surface. Knowledge about the clinical benefits of the roughness of titanium root-form surfaces is expanding. Future mechanical trials are needed to support the hypothesis that the strength of the interface between bone and implant is improved. www@implantoloji.info (JDI editor) Mon, 29 Sep 2008 01:00:00 -0400 http://www.implantoloji.info/articles/15/1/Treatment-Of-A-Microvascular-Reconstructed-Mandible-Using-An-Implant-Supported-Fixed-Partial-Denture/Page1.html Mehmet Dalkiz, DDS, PhD, Bedri Beydemir, DDS, PhD, Yilmaz Gunaydin, DDS, PhD.Department of Prosthetic Dentistry, Gulhane Military Medical Academy, Ankara, Turkey.Department of Oral and Maxillofacial Surgery, Gulhane Military Medical Academy, Ankara, Turkey.Oral rehabilitation of patients with mandibular discontinuity defects is a problem that faces both the oral surgeon and the restorative dentist. Advances in microvascular surgery can provide the mandible with vital bone grafts. Often, reconstruction of the bony defect alone does not guarantee an adequate foundation for successful conventional prosthetic rehabilitation. Osseointegrated implants placed in the microvascularized grafted bone offer an opportunity for improved function and patient satisfaction. This case report describes the use of an implant supported bridge in a vascularized fibular bone graft to reconstruct a traumatic partially resected mandible. www@implantoloji.info (JDI editor) Sun, 07 Sep 2008 01:00:00 -0400
