Anchorage has been defined as a resistance to unwanted tooth movement. It is imperative for the treatment of both dental and skeletal malocclusions. Skeletal anchorage provides better chances obtain absolute in orthodontic The topic vast compiling it one single article will be an injustice readers. So, we have divided this into two review articles under headings introduction, evolution historic...

introduction: treatment ofcleft lip and palate patients requires a multidisciplinary plan. these patients usually have a hypoplastic maxilla due to the prior surgical scars. orthognathic surgery to advance the maxilla in these patients is not very efficient; therefore, orthopedic interventions during an appropriate age seems to be essential.   case report: in this article, two cleft lip and pal...

Abstract This article presents a numerical study on the influence of anchorage shear hysteresis seismic response nonstructural components (NSC) connected to multi-storey reinforced concrete (RC) buildings, and itself. To cover variety different types shapes, this contribution considered experimental results obtained for five post-installed anchors. The were used calibrating model connecting an ...

Grouted post-tensioned (PTd) concrete systems are widely used in long-span segmental bridges with a target service life of 100+ years. However, the usage inadequate grout materials and grouting practices have resulted formation unwanted air voids duct, which turn led to premature corrosion (say, within about 20 years) strands failure tendons. Also, re-grouting/repairing void regions localized a...

This study evaluated the biomechanical influence of apical bone anchorage on a single subcrestal dental implant using three-dimensional finite element analysis (FEA). Four different bone anchorage designs were simulated on a posterior maxillary segment using one implant with platform switching and internal Morse taper connection as follows: 2 mm subcrestal placement with (SW) or without (SO) th...

This research program is intended to verify the influence of using distributed external U-wrap CFRP anchorage to shift the failure mode from overall debonding to sectional flexural failure for concrete beams externally bonded with CFRP sheets. Premature cover delamination and FRP debonding are predominant failure modes in FRP flexural strengthening that may be delayed or prevented by using FRP ...

background platelet rich plasma is known for its hemostatic, adhesive and healing properties in view of the multiple growth factors released from the platelets to the site of wound. the primary objective of this study was to use autologous platelet rich plasma (prp) in wound beds for anchorage of skin grafts instead of conventional methods like sutures, staplers or glue. methods in a single cen...
