Journal of Osseointegration <p>The aim of the&nbsp;<strong>Journal of Osseointegration</strong> in the Implant Dentistry field is to publish high quality contemporary, timely, innovative, interesting and clinically relevant information that will be used for improvement of the care of our patients. The rapid growth of research and more application of advanced clinical procedures has led us to start this new journey, that we hope will be a journey of success.</p> © Ariesdue srl, Milano, Italy.

Report of two cases <p class="p1"><span class="s1"><strong>Aim </strong></span>The aim of this study was to report and compare two cases with a significant atrophy of the posterior maxillae treated with an atraumatic, innovative procedure for maxillary sinus lift by crestal approach.</p> <p class="p1"><span class="s1"><strong>Materials and methods </strong></span>Two patients with partial edentulism in the posterior maxillae with inadequate bone volume were treated with SinCrest® procedure (Meta, Reggio Emilia, Italy). The sinus lift was performed with the simultaneous placement of the implants (three in the first case, one in the second), and after 6 months an X-ray was taken to assess the success of the treatment.</p> <p class="p1"><span class="s1"><strong>Results </strong></span>SinCrest® proved to be a mini-invasive atraumatic procedure, efficient in sinus floor elevation for the placement of single or multiple implants. Moreover, it showed a good crestal bone increase particularly with multiple implants, comparable to that obtained with a lateral window approach.</p> <p class="p1"><span class="s1"><strong>Conclusions </strong></span>This technique resulted to be a valid alternative for sinus floor augmentation thanks to its mini-invasive, atraumatic and safe procedures in cases of residual alveolar bone of at least 3 mm height.</p> A.

Specific inclusion criteria were set and tooth preparations were standardized and performed by undergraduate students under the supervision of 2 expert prosthodontists. CAD/CAM Co-Cr frameworks were fabricated and veneered with ceramics. The restorations were cemented using a self-etching, dual-cure resin luting agent. The patients were recalled at follow-up every 6 months after<span class="Apple-converted-space">&nbsp; </span>baseline evaluation, for a total observational period of 4 years. The survival and success rates of the restorations were evaluated. The technical and esthetic outcomes were examined using the United States Public Health Service criteria. The biologic outcomes were analyzed at abutments and contralateral teeth and descriptive statistics were performed.</span></p> <p class="p1"><span class="s1"><strong>Results </strong>None of the SCs was lost at follow-up, resulting in 100% cumulative survival rate and 99.2% cumulative success rates. No losses of retention were recorded. One hundred and eighteen restorations were rated alpha in all the measured parameters. A minor chipping of the veneering porcelain was detected in 1 restoration. No significant differences between the periodontal parameters of<span class="Apple-converted-space">&nbsp; </span>test and control teeth were observed.</span></p> <p class="p1"><span class="s1"><strong>Conclusions </strong></span>CAD/CAM Co-Cr single crowns proved to be a valid treatment option and a viable alternative to noble metal-ceramic restorations in posterior regions after 4 years of clinical function.</p> R.

After extraction, implants were placed immediately in fresh sockets. After randomization process, in group A immediate loading was performed while in group B a delayed loading protocol was followed. In both groups mean marginal bone loss was measured through intraoral digital radiographs at 3, 6, 12 and 24-month follow-up.</span></p> <p class="p3"><span class="s1"><strong>Results </strong>At 24-month, a survival rate of 100% was reported. For group A a mean marginal bone loss of 0.10 ± 0.09 mm was found, while for group B a value of 0.11 ± 0.08 mm was measured.

The scientific literature shows that post-extraction implants do not modify the pattern of bone remodeling secondary to dental extraction. The use of contextual bone regeneration techniques has proven effective in preventing or reducing this bone resorption. The purpose of this case report<span class="Apple-converted-space">&nbsp; </span>is to assess the maintenance of the buccal bone volume around an early implant through an analysis with TC dental scan<span class="Apple-converted-space">&nbsp; </span>one year after the delivery of the prosthesis.</span></p> <p class="p1"><span class="s1"><strong>Case report </strong>A 40 years old man with periodontitis came under our observation. After periodontal treatment<span class="Apple-converted-space">&nbsp; </span>careful extraction in the premolar area was performed and after 4 weeks an implant was inserted as well as a simultaneous bone grafting was performed with collagen membrane to reduce post-extraction socket-shrinking. After osseointegration period (4 months) the implant was loaded and the clinical and radiographic follow-up is presented. A computed tomography (TC) analysis before and one year from loading was also made to show the preservation of hard tissues and the integrity of the buccal bone plate. </span></p> <p class="p1"><span class="s1"><strong>Conclusion </strong>The use of bone regeneration around immediate implants can help to obtain good functional and esthetic outcomes. 3D radiographic study demonstrates that the buccal bone can be preserved one year after loading.</span></p> A.
