AIM To analyse the effect of leucocyte- and platelet-rich fibrin (L-PRF) on bone regeneration procedures and osseointegration. MATERIALS AND METHODS An electronic and hand search was conducted in three databases (MEDLINE, EMBASE and Cochrane). Only randomized clinical trials, written in English where L-PRF was applied in bone regeneration and implant procedures, were selected. No follow-up re...

Successful osseointegration of the dental implants requires sufficient bone volume surrounding implant site. The mandibular ramus is considered reliable donor site for reconstructing alveolar ridge defects prior to dental implant placement. The aim of this study was to present the clinical efficiency of using ultrasound surgery for harvesting mandibular ramus bone graft. 20 patients (10 male, 1...

To test the role of the miR17-92 (miR) cluster in dental bones, we evaluated the incisor tooth phenotype by micro-CT in 5- and 12-week-old conditional knockout (CKO) mice deficient in the miR17-92 cluster in type-I collagen-expressing cells and bone strength by finite element analysis. The incisor teeth of CKO mice showed a 23-30 % reduction in tissue volume and bone volume. Accordingly, the st...

BACKGROUND Animal and human researches have shown that immediate implant placement into extraction sockets failed to prevent socket dimensional changes following tooth extraction. It has been suggested that a minimal width of 1-2 mm of buccal bone is necessary to maintain a stable vertical dimension of the alveolar crest. AIM To determine the dimensions of the bony wall at extraction sites in...

Cone beam computed tomography (CBCT) can be used for determining the height and width of alveolar bone surrounding implant site which are important factors in planning. This study was done to evaluate compare maxillary anterior teeth based on CBCT images from Nepalese population. retrospective included patients who had scan between January 2019 December 2020. Sagittal section views perpendicula...

Objectives: The aim of this study is to evaluate the bone height and its width on panoramic radiography prior dental implant placement.
 Review: This was carried out using scoping review methods. referenced articles were published between 2010-2021 in English or Indonesian. search performed PubMed PMC database with keywords “(((Evaluation) AND (Presurgical)) (Dental Implant)) (Radiograph))...

alveolar echinococcosis (ae), which is caused by ingestion of eggs of the fox tapeworm echinococcus multilocularis , is the most potentially lethal parasitic infection because of its tendency to invade and proliferate in the liver and the difficulty in treatment. this article describes a case of alveolar echinococcosis found in ateles geoffroyi in mashhad, iran. the cysts were characterized as ...

Monoidal width was recently introduced by the authors as a measure of complexity decomposing morphisms in monoidal categories. We have shown that category cospans graphs, and its variants can be used to capture tree width, path branch width. In this paper we study matrices, an extension different open where connectivity information is handled with matrix algebra graphs are composed along edges ...

Introduction: The bone volume maintenance is important for ideal esthetic and functional outcomes. Due to the resorption, there a loss of socket width three dimensionally resulting in narrowing shortening alveolar ridge contour. In present study we aim evaluate autogenous demineralized dentin (ADDM) graft formation new bone. Materials Methods: We compared 200 extraction sites with ADDM various ...
