Controlling Systematic Perioperative Anaerobic Contamination During Sinus-Lift Procedures by Using Metronidazole: An Innovative Approach
Analysis of tomodensitometric controls following sinus grafts clearly demonstrates a quite systematic lack of homogeneity. Sinus contamination by anaerobic bacteria seems almost unavoidable during bone graft surgery, and this problem may jeopardize the healing process.The aim of this study was to characterize in a systematic way the nonhomogeneities observed at 1,2,or 3 months post surgery within allogenous sinus grafts,and to assess the possible influence of a 0.5% sterile solution of metronidazole in corporated in the sinus bonegraft.

Legal Considerations in the use of Cone Beam Computer Tomography Imaging
Cone beam computed tomography imaging represents a paradigm shift for enhancing diagnosis and treatment planning. Questions regarding cone beam computed tomography’s associated legal responsibility are addressed, including cone beam computed tomography necessity, recognition of pathosis in the scan’s entire volume, adequate training, informed consent and/or refusal and current court status of cone beam computed tomography. Judicious selection and prudent use of cone beam computed tomography technology to protect and promote patient safety and efficacious treatment complies with the standard of care.

Sinus Augmentation for Single-Tooth Replacement in the Posterior Maxilla: A 3-Year Follow-up Clinical Report
A technique for single-tooth sinus lift and simultaneous implant placement in the posterior maxilla is presented. Ten hydroxyapatite-coated cylindric implants, 13 to 15 mm in length, were placed together with a composite bone graft of demineralized freeze-dried bone allograft and autogenous bone in 10 adults. Surgical technique and anatomic considerations are discussed. Follow-up of 3 years showed successful function and no cervical bone loss in all patients.

Intraoral Autogenous Block Onlay Bone Grafting for ExtensiveReconstruction of Atrophic Maxillary Alveolar Ridges
Autologous bone grafting used with dental implants was originally described by Bränemarketal in 1975, and is now a well-accepted procedure in oral and maxillofacial rehabilitation.Placement of an endosseous implant requires sufficient bone volume for complete bone coverage. Furthermore, the pattern of ridge resorption contributes to an unfavorable maxillomandibular relationship, requires angulations of the implants and/or angled abutments, and affects the proximity of adjacent facial concavities(maxillary sinus, nasal cavity) and vital structures(mandibular nerve).

Impact of Smoking on Marginal Bone Loss
To compare marginal implant bone loss (MBL), survival, and radio graphic evidence of success of dental implants among smokers and non smokers.
