Abstract Aims: To explore the relationship between primary implant stability and different parameters related to or bone properties. Materials methods: Twenty‐four patients received a total of 136 Straumann SLActive implants. Resonance frequency analysis (RFA) was performed at placement, RFA Periotest (PTV) were scored loading. Bone density [Hounsfield (HU) scores] coronal cortical thickness osteotomy sites measured from pre‐operative computerized tomography scans. Results: Implant length,...

Abstract Background and Purpose Osteoporosis is a major skeletal disease affecting millions of people worldwide. Recent studies claim that patients with osteoporosis do not have higher risk early implant failure compared to non‐osteoporotic patients. The aim this study was assess the effect local bone density on initial dental stability. Materials Methods Seventy‐three were recruited assigned (based Dual‐energy X‐ray Absorptiometry scan) either (Opr), osteopenia (Opn), or control (C) group....

Implant stability is one of the most important factors influencing osseointegration. Using stereolithographical guides for maximizing precision, this study aimed at investigating relationship between implant and bone density derived from computerized tomography analysis.One hundred ninety-five implants were placed in 48 patients using digitally designed surgical guides. Ninety-five a mucosa supported guide 100 guide. was measured by means resonance frequency analysis (RFA) damping capacity...

Abstract Introduction and aim Buccal bone thickness is considered to be an important factor during implant surgery. Its resorption might have effect on the soft tissue stability eventually survival. This study aimed investigate of buccal over first 12 months after loading. Materials methods Twenty‐four subjects (47 implants) were included. The was measured surgery at several distances from shoulder using a specifically designed device which allows measurements without elevation...

The impact of osteoporosis on implant treatment is still a matter debate in the scientific community, as it may possibly lead to higher failure rates. As long-term controlled trials are missing, aim this study was verify outcome implants placed patients with systemic osteoporosis. Postmenopausal women need underwent bone mineral density measurements hip and spine, using dual X-ray absorptiometry scans. Based T-scores, they were divided into 2 groups: group O (osteoporosis group) T-score ≤−2...

Abstract Introduction: The purpose of this study was to analyze the evolution implant mechanical stability in different types/sizes bony defects using both Periotest and Osstell devices as “objective tools.” Materials methods: Thirty‐two implants were randomly allocated one four types bone defects: marginal loss, peri‐apical defect, constant width dehiscence length dehiscences. Periotest/Osstell measurements completed before during staged removal (to enlarge defect size). Results:...

Snake melon (Cucumis melo subsp. L. var. flexuosus (L.) Naudin) is an ancient and traditional crop in the Mediterranean region. Nevertheless, there has been poor interest assessing snake germplasm where its genetic resources have not surveyed before despite their potential adaptation to environmental changes. In this study, we assess diversity of landraces collected from different Lebanese regions at both morphological molecular levels. Morphological characterization using a set 18...

Safeguarding grapevine biodiversity is one of the main concerns in viticulture today. Management ex situ collections requires a comprehensive characterization conserved germplasm to provide basic material for selection and breeding programs. In this study, local at national collection Lebanese Agricultural Research Institute composed 43 accessions was submitted genetic ampelographic study. Nine ISSR primers, previously developed grapevine, were used These primers generated total 51 bands,...

Abstract Background and Purpose Osteoporosis is a disease affecting more than 300 million people worldwide responsible for numerous medical complications. This study aimed to investigate the relation between skeletal maxillary bone density. Materials Methods Seventy‐three patients were recruited divided group A (osteoporosis), B (healthy, control), C (osteopenia) on basis of dual‐energy x‐ray absorptiomery ( DXA ) scan. These also received CT scan which density measurements performed at five...

One of the major factors governing implant success is quantity and density host bone. The aim this work was to determine whether mandibular bone texture cortical width measurements on plain radiographs could be associated with failure and/or marginal loss.A statistical model built predict failure; it incorporated several radiographic features cancellous texture, width, patient smoking habits. Cortical were made panoramic 460 subjects. These used loss after 5 years. Receiver operating...

To validate in vitro the accuracy of a novel method for bone augmentation horizontal alveolar defects with help surgical guide.Six cone-beam computed tomography scans patients requiring were segmented and 3D printed. Two surgeons performed surgery twice each case on 3D-printed models, using either conventional or guided protocol. Each surgeon virtually planned desired graft shape beforehand. The resulting grafts compared linearly volumetrically to plan; density time also analyzed.There was...

<title>Abstract</title> Lebanon's well-documented history in grape cultivation and winemaking dates back millennia, intertwining with its cultural heritage landscape. However, grapevine genetic resources have received limited attention until recent years. This study presents a comprehensive exploration characterization of Lebanese local underexploited resources, beginning the collection 276 accessions prospected throughout country, an emphasis on old/abandoned vines vineyards. Molecular...

Background Implant stability has a major impact on the achievement of osseointegration, and micromobility been identified as possible cause for development fibrous capsule around implants.. Resonance Frequency Analysis (RFA) damping capacity assessment (Periotest) are two widely investigated objective reliable methods measuring translational (lateral) primary stability. Aim/Hypothesis The aim this prospective study was to assess relationship between implant number bone related features....
