Is there a need for standardization of tightening force used to connect the transducer for resonance frequency analysis in determining implant stability?
CONCLUSION: In this in vitro model experiment, transducer torques between 10 and 17 Ncm appear to be adequate for accurate measurement of implant stability, allowing more precise comparisons without damaging the prosthetic connection in the implant.

Narrow-diameter implants in the anterior region: A meta-analysis.
CONCLUSION: Single crowns supported by NDIs are a predictable treatment, since their survival rate and MBL are comparable to those supported by regular-diameter implants. Due to data shortage reporting esthetic outcomes, more studies are needed to evaluate the long-term performance of the single crowns supported by NDIs in the anterior region.

The influence of bone loss on peri-implant bending strain under overdentures.
CONCLUSION: Peri-implant bending strains rapidly increased on the loading side as bone loss levels increased. Peri-implant bending strains on the nonloading side were higher at bilaterally even bone loss than at unilateral bone loss.

Influence of surgeon experience on the accuracy of implant placement via a partially computer-guided surgical protocol.
CONCLUSION: The level of surgeon experience affects the accuracy of implant placement using a teeth-supported surgical guide; therefore, the use of computer-guided surgery via a partially guided protocol does not completely compensate for the level of operator experience. However, such surgical guide might be used in a whole task training of novice surgeons, as it can bridge the gap between simulation training in vitro and freehand surgery in a clinical setting.

Effect of ovariectomy on tissue-level changes in rat maxilla.

Stud vs Bar Attachments for Maxillary Four-Implant-Supported Overdentures: 3- to 9-year Results from a Retrospective Study.
CONCLUSION: Within the limitations of this study, no significant differences were indicated between the clinical outcomes of maxillary four-implant-supported overdentures with either stud or bar attachments, although a higher modified Plaque Index was observed for the bar-retained group. Furthermore, prostheses with stud attachments were advantageous for their convenient cleaning and repair. Patients with compromised systemic and periodontal conditions should be treated with caution.

Axial displacement in cement-retained prostheses with different implant-abutment connections.
CONCLUSION: In implant connections with a vertical stop, axial displacement occurred primarily in the early loading period and was self-limited. However, long-term axial displacement can occur with internal conical connection implants. Therefore, in internal conical connection implants, axial displacement should be managed more carefully using a provisional restoration, with consideration of the abutment fabrication method.

Use of Patient-Specific Finite Element Models in Dental Rehabilitation to Investigate Stresses of a Fibula Free Flap for Mandibular Reconstruction.
CONCLUSION: Both implant length and diameter were influential; stresses were seen to decrease to a minimum then subsequently increase as either dimension increased. Additionally, stresses in bone introduced by an implant decreased as the degree of interaction between the implant and fibula increased.

Effect of Misfit at Implant-Level Framework and Supporting Bone on Internal Connection Implants: Mechanical and Finite Element Analysis.
CONCLUSION: This study confirmed that implant fracture is an unlikely adverse event. A clear pattern of effective distribution greater than fatigue limit stresses could be noticed when the misfit was present. The dynamic load simulation demonstrated that the crack is more likely to occur when implants are fully supported by marginal bone compared with a bone loss scenario. Within the limitations of this study, it is speculated that marginal bone loss might follow the appearance of an undetected crack. Further research is needed to develop safe clinical protocols with regard to ILFPD. PMID: 30883615 [PubMed - in process...

A Critique of Resonance Frequency Analysis and a Novel Method for Quantifying Dental Implant Stability in Vitro.
CONCLUSION: The results obtained from resonance frequency analyses did not accurately represent dental implant stability. Changes to implant length and diameter did not affect resonance frequencies. In contrast, angular stiffness at the neck of the implant represented a superior index for quantifying dental implant stability. It not only successfully differentiated stability of implants of both varying lengths and diameters, but also produced quantitative data that was independent of the type of abutments used.

Ultraviolet Light Treatment of Titanium Suppresses Human Oral Bacterial Attachment and Biofilm Formation: A Short-Term In Vitro Study.
CONCLUSION: UV treatment of titanium surfaces significantly reduces attachment of human oral bacteria and subsequent biofilm formation as well as EPS production for at least 7 days. UV treatment prevented the escalation of surface colonization, mitigating an unfavorable bacteriophilic cascade and environmental trigger for biofilm formation.

The Biological Effect of Particulate Titanium Contaminants of Dental Implants on Human Osteoblasts and Gingival Fibroblasts.
CONCLUSION: Cell viability is negatively correlated with titanium concentration. Further, titanium debris might lead to an inflammatory biologic response of dental peri-implant tissue. Also, cells interact with the debris, eg, with incorporation of particles. PMID: 30807628 [PubMed - as supplied by publisher] (Source: International Journal of Oral and Maxillofacial Implants)

Integrity of Human Mandibular Angle After Block Graft Harvest from Mandibular Body.
CONCLUSION: After subjected to a typical block graft harvest surgical procedure, the human mandible's integrity is significantly altered. Gender, dental status, and mandibular bone height do not correlate with maximal load,and thus integrity, of donor and control mandibles.

Volumetric Analysis of Allogenic and Xenogenic Bone Substitutes Used in Maxillary Sinus Augmentations Utilizing Cone Beam CT: A Prospective Randomized Pilot Study.
CONCLUSION: Both DBB and MAB showed sufficient volume stability at T2 (mean 6.3 ± 1.6 months) postoperatively for 10- to 13-mm-implant placement without the need for additional grafting.
