Soft Tissue Substitutes: Current Biomaterials and Indications at Teeth and Implant Sites

open access: yesJournal of Periodontal Research, EarlyView.
This manuscript provides an updated overview of the current evidence on soft tissue graft substitutes for teeth and dental implants. When appropriately indicated, these biomaterials offer a reliable, less invasive alternative to autogenous grafts, effectively improving root coverage, keratinized mucosa width, and soft tissue thickness with reduced ...

Clinician‐ and patient‐reported outcomes following the surgical treatment of single gingival recession defects: A systematic review

open access: yesPeriodontology 2000, EarlyView.
Abstract To analyze the effect of root coverage surgical therapy for the treatment of single gingival recession defects (GRD) in terms of clinician‐ and patient‐reported outcomes (CROs and PROs), with an emphasis on esthetic perception. The protocol of this PRISMA 2020‐compliant systematic review was registered in PROSPERO (CRD517050).

Comparison of calculation models’ estimates with actual measured autogenous shrinkage in High-Performance Cement Composites

open access: yesMATEC Web of Conferences, 2018
There are several calculation models for estimation of shrinkage in concrete. The most popular ones are: ACI-209R-92 method, Bažant-Baweja model (B3), Gardner’a-Lockman’a model (GL 2000), CEB-FIP (CEB MC90-99), Spanish model (EHE), EuroCode method (EC-2)

Long‐term stability of transcrestal sinus augmentation

open access: yesPeriodontology 2000, EarlyView.
Abstract Transcrestal sinus augmentation has emerged as a minimally invasive alternative to lateral window techniques for vertical bone augmentation in the edentulous maxilla. Since its early introduction and modification over the last several decades, this technique has demonstrated predictable outcomes for implant placement in regions with limited ...
