Precise radiographic planning of implant areas influences the treatment planning both from the surgical and the prosthodontic point of view. Thorough radiographic assessment reduces the incidence of complications. Early recognition of failure helps in dealing with complications. This book is an innovative issue dealing with radiographic techniques for the placement and assessment of endosseous oral implants. It is a practical guide for all those involved in oral implant surgery and prosthetic rehabilitation. Richly illustrated with radiographs, overview tables and flow diagrams it provides step by step procedures for the planning and assessment of oral implants.
This retrospective research was performed to evaluate the marginal bone level changes around dental implants with various types of prosthetic restorations in the posterior regions of the maxillary bone that were placed by clinicians at an academic institution. Intraoral radiographs were used to evaluate the peri-implant bone level changes. The results demonstrated that there were significant differences between implants restored by platform-switching vs. platform-matching on the mesial and distal at the prosthetic restoration and the 1-year visits, and between implants in patients with diabetes vs. non-diabetes on the distal at the 1-year visit. This study complemented the present scarce literature on this topic through the identification of patient-related and implant-related characteristics that may contribute to peri-implant bone loss.

As an unstable implant at time of placement has been identified as a major cause of early implant failure, the technical requirements of achieving and maintaining implant stability are important prerequisites for successful clinical outcomes with dental implants. Recently, new implant designs and surfaces have been introduced to decrease the risk of early failure of dental implantsThe purpose of this study was to evaluate the short-term clinical and radiographic efficacy of a novel implant design and to evaluate the relative importance of achieving primary stability at placement over a 36-months period. This retrospective study includes 64 partially or fully edentulous patients treated between June 2014 and September 2017. Outcome measures were: implant and prosthetic failures; peak insertion torque values ; biological and mechanical complications; marginal bone loss (MBL); sulcus bleeding index (SBI); and plaque score (PS). Clinical and radiographic checks were performed as routinely in the office at implant placement, clinical check-up before the permanent prosthesis at 3 months, and at the 6, 12, 24 and 36 months follow-up visits.A total of 119 (31 narrow platform 3,75 mm, 68 regular platform - 62 RP 4,3 and 6 RP 5mm- and 20 wide platform 5,5mm) NobelParallel Conical Connection implants were placed in both post-extraction sockets and healed sites. 28 implant were immediately loaded. The mean insertion torque was 46,09 Ncm. 108 out of 119 implants (90,75%) were inserted with a torque superior to 35 Ncm.Each patient received a single or multiple-unit prosthesis. After 36-month of follow-up, only one implant failed (1,19%) in a healed sitebefore prosthesis installation. No other biological or technical complications were observed during this short follow-up. The mean MBLat baseline was +1,23 mm The mean MBL from insertion was -0,51 mm , 5,04% of the implants (n=6) showed bone loss of more than1 mm. All implants showed no bleeding on probing and plaque accumulation was very low (4,20%).The NobelParallel Conical Connection implant can be considered as an effective treatment option for implant placement in the partially or fully edentulous patients over a 36-months period in both jaws. This implant provides high but controlled insertion torques in all bone qualities and appear to be less technique-sensitive than other implant systems because of its parallel apically tapered design and its simple, straight forward and versatile drilling protocol.
This book explores, in a comprehensive and systematic manner, Surgical Research methodologies to the design and development of investigational studies in the field of implant-based oral rehabilitation. Such studies are linked in a chain binding in vitro, in vivo, ex vivo, and digital evaluations. An ambitious objective consists in exposing how investigators can generate and deliver knowledge by capturing synergy coming from preclinical and clinical trials. Accordingly, throughout the book, translational aspects are closely scrutinized. The opening chapters consider materials, methods and procedures for preclinical and clinical studies in which approaches and models are extensively described. The focus then moves to the process by which application of histology, biomechanics, biomarkers, cellular/molecular biology, and imaging technologies lead to new results and consequently novel treatment concepts in implant dentistry, implant borne prosthetic rehabilitations and the replacement or regeneration of tissues. Finally, the exciting opportunities afforded by the digital world are addressed. This book shall be a valuable resource and time-saving tool for a wide audience of researchers, students, practitioners, and academics.
The establishment of osseointegration following dental implant placement is a major contributing factor to the clinical success and long-term function of implant-retained prosthesis, Radiographic examination and palpation have been two of the methods often used in clinical assessment for implant stability for years However, theses radiographs are two-dimensional and difficult to standardize, The investigation was designed to study the use of resonance frequency analysis in search of the stability of the implant-issue interface in vitro, Resonance frequency was measured when test implants were embedded in bakelites, The change in stiffness observed during bone healing was modeled by embedding implants in gypsum during setting period, Our results showed that there was an increase in resonance frequency related to stiffness increment during osseointegration,
