Special Issue Information

Dear Colleagues,

This Special Issue will give an up-to-date view of the Biomechanics of Bone Tissue and Dental Implants, useful both for academic researchers and clinicians in their daily practice. Topics covered will include the different behaviors under loading of different types of bones, ranging from D1 to D4; the bone modeling and remodeling; and the importance of different implant shapes; thread configurations, implant–abutment connections, and implant surfaces for best achieving long-term implant success. The clinical implications and benefits for patients could be very significant and related to the understanding of optimal implant positioning (over the implant crest, at the level of the crest, under the crest), the use of the immediate loading and immediate post-extraction implants concepts and techniques, such as the healing of the alveolar socket. Also, what happens to peri-implant mineralized tissues in the long term (even more that 3 decades) will be discussed.

We welcome colleagues involved in this field to contribute original articles or reviews to this Special Issue.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Osteology is an international peer-reviewed open access quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1000 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Background/Objectives: The primary aim of this study is to evaluate the impact of two different drilling methods on the primary stability of implants inserted into polyurethane blocks simulating different bone densities. The secondary aim is to analyse the indication provided by three different methods used to assess primary stability. Methods: The study was performed on two artificial bone blocks of solid rigid polyurethane without cortical layer and one laminated one. A total of 48 implants were placed following either a Regular Primary Stability (RPS) or an Enhanced Primary Stability (EPS) protocol based on site underpreparation. Immediately after implant placement, artificial intelligence tool (AIT) indication, peak insertion torque (pIT) and Resonance Frequency Analysis (RFA) values were recorded. The values were then categorised as suitable or not suitable for single-crown immediate loading by bone density and drilling protocol. Results: EPS drilling protocol produced significantly higher primary stability values than those in all bone densities, regardless of the primary stability measurement method used, except for the implants placed in D4 and evaluated by AIT. The grouping of values shows that implants placed in D3 and D4 never reached the immediate loading threshold for a single crown. In D2, EPS and RPS protocols both reach the threshold for all implants when evaluated with pIT or RFA; when AIT is used, RPS protocol was not able to reach the single-crown threshold in 50% of cases. Conclusions: Within the limitations of this in vitro study, underpreparation appears a viable technique to improve primary stability, nevertheless it might be insufficient to reach the threshold of immediate loading suitability in low density bone. All systems used are able to report the primary stability increase obtained by underpreparation, but AIT showed the potential to detect a loss of primary stability related to torque drop during insertion. These findings require further confirmation. Full article

Background: The present case report study aims to describe, from both clinical and histological aspects, the bone healing pattern in a patient under oral bisphosphonates therapy. Case Presentation: an 82-year-old female patient has been under oral nitrogen bisphosphonates therapy for two years. She underwent a tooth extraction. After four months, two bone biopsies were harvested, during standard implant drilling procedures. The first one corresponded to the healed alveolar socket of the previously extracted tooth (specimen A), while the second one corresponded to the bone ridge that was edentulous before starting the bisphosphonates therapy (specimen B). Morphometric and histologic analyses were performed. Results: In both, the bone resulted vital and no evidence of empty lacunae was detected. A reduction in the haversian canal diameter was observed in specimen B. The present case report highlights histological findings suggesting that patients undergoing oral bisphosphonates therapy may be eligible for surgical therapy. A pre-operative careful anamnesis and the observance of international guidelines for treating patients taking bisphosphonates are mandatory. Conclusions: These preliminary results will be used to plan a large clinical study in order to better understand the influence of bisphosphonates on the bone healing process. Full article
