\nDepth of the Implant stability defines the success of Osseointegration.
\nRegular monitoring on the certain stages of implants in a qualitative way helps us analyze the stability and harmonization levels of the implant.
\nImplant stability is defined as the capacity and strength of the implant to withstand loading in axial, lateral and rotational directions.
\nOsseointegration measures the stability of implants and that happens in two stages:
\nPrimary:<\/strong> Osseointegration is said to be successful through the mechanical attachment of cortical bone. It is affected by the quantity and quality of the original bone.
\nSecondary:<\/strong> the process of healing Osseo implants by regenerating and remodeling of new tissues and bone. It is affected by the primary stability.<\/p>\n

\nTraditional healing takes 3 to 6 months and it is essential for the successful osseointegration and maintenance of functional loading.
\nFunctional loading and Immediate loading depend upon the implant’s stability.
\nBefore the evolution of technology, Implants stability was measured using microscopic observations and radiographs, however with the innovations in the technology, researchers have focussed on reduction of Osseo healing phases, treatment time and have come up with new Implant stability measures.
\nIt is obvious that the Osseointegration mostly depends upon the health and strength of the surrounding tissues of the bone implanted area.
\nDifferent measures are derived in concern with the characteristics of the implant surface.
\nPlatelet-rich plasma (PRP) is one such new approach that helps in quick Osseo healing of endosseous implants.<\/p>\n
\nHave you heard about PRP (Platelet-rich plasma) in dentistry? What does it do in the body? How is it formed?
\nPlatelet-rich plasma is explained as a high concentration of platelets in small amounts of autologous plasma.
\nPlasma releases alpha granules in the coagulation process and is triggered in the wounded area.
\nAlpha granules are a cocktail of growth factors and promote proliferation, chemotaxis(tissue generation) that helps in healing the wound, therefore Platelet-rich plasma (PRP) has become one of the effective measures that accelerate the bone repair and heals the wound earlier than expected.
\nPRP is generated from the patient’s own blood and it is released continuously for seven days, it has a low PH rate (6.5 \u2013 6.7) which prevents bacterial growth and leads in fast healing.
\nPRP promotes fibroblast, proliferation and increases tissue vascularity.<\/p>\n
\nPRP is used in the form of a gel, this gel is prepared in the combination of thrombin, calcium chloride, high concentrations of platelets and native concentration of fibrinogen from the whole blood.
\nAdding calcium chloride and thrombin to PRP activates the alpha granules and biological factors which leads to quick healing of the wound.<\/p>\n
\nHow is PRP applied and measured to treat the stability of dental implants?<\/strong><\/p>\n
\nThis case study is approved by the Institute of Ethical Committee.
\nA random clinical study was conducted in 2012-15 in SIBAR Institute of Dental Sciences in Andhra Pradesh.
\nTen healthy patients with adequate bone width and height between ages 25 to 40 years were selected and a total of 18 implants were placed with a standard size of 3.75*10mm to prevent variations on the implant surface.
\nAll the ten patients were explained about the process and written consent was taken from them.
\nPreoperative bone height was measured from the vertex of the ridge to the highest border of the inferior alveolar nerve canal using Digital Panoramic radiograph.
\nThe dental model was used as a template for ridge mapping and to prepare the surgical stunt.
\nRidge mapping technique is used to assess the thickness of the soft tissue and the width of the bone already present.
\nKappa correlation was used to assess the observer’s analysis for the assessment.<\/p>\n
\nVenous Blood was taken following the necessary precautions and it was carefully transferred from antecubital fossa to sterile vacutainer containing 0.5ml of 3.2% sodium citrate as it is anticoagulant in nature.
\nIt was titrated and subjected to centrifugation at 2400rpm for ten minutes, this separates platelets and plasma from whole blood.
\nThe plasma obtained was recentrifuged at 3600rpm for 15 minutes to concentrate the platelets into plasma.
\nTwo types of plasma were collected at the bottom of the vacutainer.<\/p>\n\n
