Tissue engineering innovations to enhance osseointegration in immediate dental implant loading: A narrative review.

The demand for efficient and accelerated osseointegration in dental implantology has led to the exploration of innovative tissue engineering strategies. Immediate implant loading reduces treatment duration and necessitates robust osseointegration to ensure long-term implant success. This review article discusses the current studies of tissue engineering innovations for enhancing osseointegration in immediate dental implant loading in the recent decade. Keywords "tissue engineering," "osseointegration," "immediate implant loading," and related terms were systematically searched. The review highlights the potential of bioactive materials and growth factor delivery systems in promoting osteogenic activity and accelerating bone regeneration. The in vivo experiment demonstrates significantly improved osseointegration in the experimental group compared to traditional immediate loading techniques, as evidenced by histological analyses and biomechanical assessments. It is possible to revolutionize the treatment outcomes and patient satisfaction in dental implants by integrating bioactive materials and growth factors.

The current applications of nano and biomaterials in drug delivery of dental implant.

BACKGROUND AND AIM: Dental implantology has revolutionized oral rehabilitation, offering a sophisticated solution for restoring missing teeth. Despite advancements, issues like infection, inflammation, and osseointegration persist. Nano and biomaterials, with their unique properties, present promising opportunities for enhancing dental implant therapies by improving drug delivery systems. This review discussed the current applications of nano and biomaterials in drug delivery for dental implants. METHOD: A literature review examined recent studies and advancements in nano and biomaterials for drug delivery in dental implantology. Various materials, including nanoparticles, biocompatible polymers, and bioactive coatings, were reviewed for their efficacy in controlled drug release, antimicrobial properties, and promotion of osseointegration. RESULTS: Nano and biomaterials exhibit considerable potential in improving drug delivery for dental implants. Nanostructured drug carriers demonstrate enhanced therapeutic efficacy, sustained release profiles, and improved biocompatibility. Furthermore, bioactive coatings contribute to better osseointegration and reduced risks of infections. CONCLUSION: Integrating current nano and biomaterials in drug delivery for dental implants holds promise for advancing clinical outcomes. Enhanced drug delivery systems can mitigate complications associated with dental implant procedures, offering improved infection control, reduced inflammation, and optimized osseointegration.

Investigation of the expression levels of miR-21, miR-132, miR-29a, miR-204, and miR-138 in patient's plasma with primary OSCCs.

This is the eighth most malignant tumor in the world, causing the highest incidence and malignancy rate of all cancers in the mouth and maxillofacial region. In cells, miRNAs regulate development, differentiation, proliferation, and differentiation, and miRNA expression is a better indicator of physiological status than DNA expression. miR-21, miR-132, miR-29a, miR-204, and miR-138 levels were measured in plasma from patients with primary OSCC and healthy controls. A Real Time-PCR technique was used to measure miR-21, miR-132, miR-29a, miR-29a, and miR-204 expression levels in plasma from 38 healthy and 38 people with primary OSCC. A standard distribution test and a CT unit were used to confirm the quantitative data on miRNA expression. Gene expression levels were compared between two groups of patients and healthy groups using a Mann-Whitney test and an unpaired t-test. MiR-21's median CT value was 29.68 in the OSCC group and 32.89 in the healthy group, and miR-29a's median CT value was 37.54 and 36.46 in the OSCC group and healthy group, respectively. Additionally, miR-132's CT values were 37.71 and 36.40, miR-138's CT value was 35.37 and 31.21, and miR-204's CT value was 36.44 and 36.17. The results showed that miR-21 expression levels increased significantly, while miR-29a, miR-132, and miR-138 (P < 0.05), and miR-204 expression levels did not differ significantly (P > 0.05). As a result of this study, the expression levels of microRNAs may be considered to diagnose OSCC at an early stage. It is essential to diagnose this disease early to improve treatment and patient health outcomes.

The current techniques in dorsal augmentation rhinoplasty: a comprehensive review.

BACKGROUND: An essential aspect of rhinoplasty is the enhancement of the nasal dorsal contour by performing dorsal augmentation (DA) rhinoplasty. A wide range of techniques are available for DA as the demand for aesthetic nasal refinement grows. This review aims to provide a comprehensive overview of the current techniques used in DA rhinoplasty. MAIN BODY: Research articles on DA rhinoplasty techniques were identified through a comprehensive literature search. Scopus, PubMed, and Web of Science were used as electronic databases. Each database was searched for articles published since its inception. DA rhinoplasty techniques were examined in this literature review. Methodological quality was assessed for the selected studies, and data was extracted to examine materials used, surgical approaches, and reported outcomes for each technique. Various DA methods, including autologous grafts and synthetic implants, are examined in-depth in this review. Comparing approaches can help better understand their respective advantages and limitations. CONCLUSION: A wealth of techniques is available for DA rhinoplasty, each with advantages. Patients' nasal anatomy, desired outcomes, and potential risks must be considered by surgeons when determining their surgical approach. DA methods continue to evolve rapidly, creating a need for a thorough understanding of the current landscape to make informed decisions.
