Published: Dec. 21, 2016

In the 1960s and 1970s, implant-supported prostheses based on subperiosteal or blade implants had a poor reputation because of questionable clinical outcomes lack scientific documentation. The change to scientifically sound discipline was initiated by two pioneers modern implant dentistry, Professor P. I. Brånemark from University Gothenburg in Sweden André Schroeder Bern Switzerland. Together with their teams, independently each other, they laid foundation for most significant development paradigm shift dental medicine. present volume Periodontology 2000 celebrates 50 years osseointegration.

Socket Shield Technique for immediate implant placement – clinical, radiographic and volumetric data after 5 years

Clinical Oral Implants Research, Journal Year: 2017, Volume and Issue: 28(11), P. 1450 - 1458

Implant placement immediately after tooth extraction is often accompanied by resorption of surrounding tissues. A clinical technique was developed where the buccal portion root retained to preserve periodontal ligament and bundle bone. This based on animal studies showing potential facial tissues utilizing this approach. The purpose study gain more insight regarding safety with regard biological implant-related long-term complications observe appearance peri-implant Another objective evaluate volumetric changes affected contours in esthetic outcomes.This a retrospective case series 10 consecutive patients implant replacement between maxillary first premolars. Impressions were made prior (t1) 5 years post-implant (t2). 3D-surface scans casts digitally superimposed for quantitative evaluation alterations tissue soft recessions. Additionally, data collected (PPD, BOP, peri-apical radiographs photographs).All implants healed without adverse events.

Vitamin K and Bone Metabolism: A Review of the Latest Evidence in Preclinical Studies

BioMed Research International, Journal Year: 2018, Volume and Issue: 2018, P. 1 - 8

Published: June 27, 2018

Bone is a metabolically active tissue that renews itself throughout one’s life. Cytokines along with several hormonal, nutritional, and growth factors are involved in tightly regulated bone remodeling. Accordingly, vitamin K as multifunctional has been recently deemed appreciable topic of research it plays pivotal role maintenance the strength, proved to have positive impact on metabolism. Vitamin exerts its anabolic effect turnover different ways such promoting osteoblast differentiation, upregulating transcription specific genes osteoblasts, activating bone-associated k dependent proteins which play critical roles extracellular matrix mineralization. There also credible evidence support effects k2 differentiation other mesenchymal stem cells into osteoblast. The main objective present paper comprehensively outline preclinical studies properties could shed light further clinical improve osteogenesis graft surgeries.

Alveolar ridge preservation: Complications and cost‐effectiveness

Periodontology 2000, Journal Year: 2022, Volume and Issue: 92(1), P. 235 - 262

Published: Dec. 29, 2022

Abstract Alveolar ridge preservation is routinely indicated in clinical practice with the purpose of attenuating postextraction atrophy. Over past two decades numerous studies and reviews on this topic have populated literature. In recent years focus has primarily been analyzing efficacy outcomes pertaining to dimensional changes, whereas other relevant facets alveolar therapy remained unexplored. With premise, we carried out a comprehensive evidence‐based assessment complications associated different modalities modeled cost‐effectiveness therapeutic as function changes width height. We conclude that, among allogeneic xenogeneic bone graft materials, increased expenditure does not translate into effectiveness therapy. On hand, significant association between barrier membrane reduced horizontal vertical resorption was observed, though only certain degree, beyond which return investment significantly diminished.

Recent Clinical Treatment and Basic Research on the Alveolar Bone

The periodontal ligament is located between the bone (alveolar bone) and cementum of tooth, it connected by tough fibers called Sharpey's fibers. To maintain healthy teeth, foundation supporting teeth must be healthy. Periodontal diseases, also known as tooth loss, cause alveolar to dissolve. bone, similar bones in other body parts, repeatedly resorbed osteoclasts renewed osteogenic cells. This means that an old constantly being replaced a new bone. In around absorbed, disease progresses, shrinks gradually. most cases, does not return its original form even after cured.

Abstract The morphology and dimensions of the postextraction alveolar ridge are important for surgical restorative phases implant treatment. Adequate new bone formation preservation following extraction will facilitate installation in a position, while soft tissue contour volume is essential an aesthetic implant‐supported restoration with healthy peri‐implant tissues. Alveolar (ARP) refers to any procedure that aims to: (i) limit dimensional changes after facilitating placement without additional extensive augmentation procedures (ii) promote healing alveolus, (iii) at entrance alveolus preserve contour. Although ARP clinically validated safe approach, certain clinical scenarios, benefit over unassisted socket has been debated it appears some clinicians may represent overtreatment. aim this critical review was discuss evidence pertaining four key objectives determine where can lead favorable outcomes when compared healing.

Abstract Aim To compare the clinical outcomes of ≤6 mm extra‐short implants (test group) versus ≥10 long (control group), with and without bone augmentation procedures. Materials Methods A systemic literature search randomized trials was performed using PubMed (MEDLINE) EMBASE databases. quantitative meta‐analysis conducted to all outcome variables. Meta‐regression analysis determined effect procedures influence other covariates on results. Results Eighteen studies comprising 1,612 (793 820 implants) were selected for meta‐analysis. No statistically significant difference in survival rate observed at 1 3 years ( p > 0.05). Extra‐short displayed less marginal loss (MBL) from both implant placement time points (1 years) prosthetic year), as well biological complications, surgical treatment cost < Contrarily, a small number complications reported Conclusions Placement (≤6 mm) presented an equivalent option patients atrophic posterior arch up 3‐year follow‐up.
