Aim: To evaluate the success rate, level of satisfaction, Retentive force, and Hard Soft tissue evaluation with implant-supported overdentures Kerator® attachment system, by means a review literature.Materials Methods: PICO approach was used for clinical question. The research conducted in PubMed®, Google scholar®, Cochrane® information sources using different strategies text words MESH terms. ...

objectives: this study was designed to assess the changes of the mandible of patients who underwent orthodontic treatment with or without extraction of four premolars. materials and methods: eighteen class i bimaxillary protrusion patients treated with extraction of four first premolars and retraction of anterior teeth and 18 class i non-extraction patients with a mean age of 16.38±0.4 years we...

The use of biomaterials to restore the function of traumatized or degenerated connective tissues and thus improve the quality of life of a patient has become widespread. In the past, implants were designed with insufficient cognizance of biomechanics. Accordingly, the clinical results were not very encouraging. An upsurge of research activities into the mechanics of joints and biomaterials has ...

Mr. P is a 69-year-old male who presents with a chief complaint of, “I have neglected my teeth for 20 years and I’d like to have them fixed.” He is a lifelong nonsmoker, in good health, with no known drug allergies and no significant past medical history. Dental findings are notable for significant edentulousness: teeth numbers 1, 2, 3, 5, 7, 10, 13, 16, 17, 18, 19, 20, 30, 31, 32 are not prese...

background: this was a retrospective cephalometric study to develop a more precise estimation of soft tissue changes related to underlying tooth movment than simple relatioship betweenhard and soft tissues. materials and methods: the lateral cephalograms of 61 adult patients undergoing orthodontic treatment (31 = premolar extraction, 31 = nonextraction) were obtained, scanned and digitized befo...

The present work is aimed at investigating the mechanical and in vitro biological properties of polyphenylene ether ether sulfone (PPEES)/nanohydroxyapatite (nHA) composite fibers. Electrospinning was used to prepare nanofiber composite mats of PPEES/nHA with different weight percentages of the inorganic filler, nHA. The fabricated composites were characterized using Fourier transform infrared ...
