PDGF‐BB‐enriched collagen matrix to treat multiple gingival recessions with the tunneled coronally advanced flap

Clinical Advances in Periodontics, Volume 12, Issue 4, Page 224-232, December 2022., 2022
Abstract Background With technological advancements in reconstructive periodontology, traditional protocols for the treatment of gingival recessions (GRs) can be challenged. This manuscript presents preliminary findings of a novel minimally‐invasive approach for the regenerative treatment of multiple adjacent GR defects. Methods Two healthy adults were

Application of biologics for ridge preservation/reconstruction after implant removal

Clinical Advances in Periodontics, Volume 12, Issue 4, Page 270-276, December 2022., 2022
Abstract Background The purpose of this review was aimed at providing the rationale supported with a series of cases to apply biologics to enhance orchestrating the healing process at implant removal sites. Summary Implant removal is commonly applied on a daily basis, in particular, in cases that exhibit esthetic failures linked to inadequate implant ...

Image Reconstruction in Cone Beam Computed Tomography Using Controlled Gradient Sparsity [PDF]

arXiv
Total variation (TV) regularization is a popular reconstruction method for ill-posed imaging problems, and particularly useful for applications with piecewise constant targets. However, using TV for medical cone-beam computed X-ray tomography (CBCT) has been limited so far, mainly due to heavy computational loads at clinically relevant 3D resolutions ...

Morphogenic Growth 3D Printing

Advanced Materials, EarlyView.
I additive manufacturing process exploits the spatial propagation of a polymerization reaction front to produce 3D polymer parts 10× faster and 1000× more energy efficient than the fastest stereolithography. In contrast with existing 3D printing, this morphogenic process is inspired by biological “growth and form” due to the self‐directed propagation ...

Bone construction surgery: A case report using recombinant human platelet‐derived growth factor‐BB

Clinical Advances in Periodontics, Volume 12, Issue 4, Page 262-269, December 2022., 2022
Abstract Background The position and condition of bone largely sets the stage for functional and esthetic implant success. In bone construction surgery, creating a sustainable functional matrix is complex, but necessary, to enable long‐term mechanotransduction and maintenance of soft tissue support.
