Comparison of Surface Treatments of Endosteal Implants in Ovariectomized Rabbits.
Authors: Parra M, Elias CN, Olate S, Witek L, Coelho PG Abstract PURPOSE: The aim of this work was to evaluate osseointegration of endosteal implants with two different surface treatments at early stages (~3 weeks) in the tibia of healthy and ovariectomized rabbits. MATERIALS AND METHODS: The study comprised 10 adult New Zealand female rabbits (Oryctolagus cuniculus; 6 months and 3.0 ± 0.5 kg). Five animals were subjected to bilateral ovariectomy to mimic osteoporotic-like conditions, and the remaining rabbits (n = 5) served as the healthy control group.

Evaluation of Bacterial Leakage in Platform-Switching Dental Implant with Morse Taper Connection Under Thermocycling and Loading Effects: In Vitro Study.
CONCLUSION: Microbial leakage at the implant-abutment connection is influenced by the applied load alone and in combination with thermocycling; however, E faecalis and S aureus did not leak at the implant-abutment connection even under these circumstances. Only P aeruginosa infiltrated inside the implant-abutment connection, which might be caused by its swarming motility.

Clinical Assessment of Preload Maintenance in the Abutment Screws of Single Posterior Implants After 1 Month of Use.
CONCLUSION: Under the experimental conditions of this study, abutment screws in some bone-level, internal tapered-connection, platform-switching implant systems showed preload loss at 1 month after abutment placement for single posterior implant-based restorations, regardless of implant system or whether abutment screws had been retightened 10 minutes after abutment placement, or implant position (premolar or molar). It is necessary to retorque the abutment screws 1 month after initial torque.

Can Finger-Generated Force Be Used Reliably to Connect the Transducer for Resonance Frequency Analysis in Determining Implant Stability?
CONCLUSION: For an accurate measurement of ISQ, the minimum torque necessary to insert the transducer into the implant for Osstell was 10 Ncm, while for Penguin, it was 5 Ncm. Therefore, when using Osstell to assess implant stability, the authors suggest the use of a torque wrench to ensure 10 Ncm of force is applied when tightening the transducer into the implant to obtain accurate stability measurements. When using Penguin, the maximum finger-generated tightening force is enough. PMID: 33270054 [PubMed - in process] (Source: International Journal of Oral and Maxillofacial Implants)

Citation Characteristics of H-Classics Articles in Implant Dentistry: A Citation Analysis Using H-Classics Method.
CONCLUSION: This study provides insightful views regarding citation characteristics of H-classics articles in implant dentistry (eg, interdisciplinary publications on bioengineering interventions) during the investigation periods, which may foster the translation of preclinical research into clinical applications in the future.

Demineralized Human Dentin Matrix as an Osteoinductor in the Dental Socket: An Experimental Study in Wistar Rats.
This study evaluated the bone-forming potential of the demineralized human dentin matrix by performing histologic and morphometric analyses. The immunolabeling of osteopontin, a determinant protein for bone repair, was also evaluated. MATERIALS AND METHODS: Wistar rats were selected and submitted to the extraction of the right and left second molars. Tooth sockets were separated into two groups: the control group (right), which was filled with the blood clot, and the experimental group (left), which was filled with demineralized human dentin matrix. Animals were sacrificed at 5, 10, and 21 days. Histologic and histoqua...

The Impact of Compaction Force on Graft Consolidation in a Guided Bone Regeneration Model.
CONCLUSION: Both compression forces applied resulted in similar consolidation of bovine hydroxyapatite expressed by new bone formation and vascularization based on a rabbit calvaria augmentation model.

Healed Edentulous Sites: Suitability for Dental Implant Placement, Need for Secondary Procedures, and Contemporary Implant Designs.
CONCLUSION: The study indicates that implants can be placed in slightly over half of edentulous sites without a secondary grafting procedure. The possibility of dental implant placement varied according to the volume and morphology of alveolar bone and related anatomical structures. This decreased from anterior to posterior in both arches. The sloped implant design was beneficial. In addition, the sloped implant design resulted in the placement of a longer implant.
