Background: Aesthetic correction involves a holistic approach which considers the oral cavity as a whole by the norms of the treatment. Aesthetics enhance the facial profile and also the smile line of the patient which improves the quality of life of a patient enabling them to a better socioeconomic status. Smile correction of a patient paves the path for a systematic approach to the treatment and also imparts an improved level of confidence which leads to new opportunities both in the personal and professional field. AeEsthetic correction provides challenging aspects concerning patient satisfaction and functional demands. This is the most affordable treatment for patients' who are not financially sound in developing countries like India. The other treatment modalities such as Veneers or All-ceramic crowns are aesthetically pleasing but are quite expensive for people in the lower income strata. Due to this, direct composite treatment is very economical and it also improves the patient's overall confidence and it helps them to socialise well and carry out their daily routine activities without any hindrance and difficulty. Case Report: This case report deals with the esthetic correction of midline diastema and spacing in the maxillary and mandibular anterior region. Conclusion: Aesthetic correction involves meticulous treatment planning to revive the essence of lost beauty as well as improve the functional aspect for the patient. [ABSTRACT FROM AUTHOR]

Esthetic dentists, these days must be well equipped to satisfy the needs of cutting edge society. All ceramic restorations have gained wide recognition as a number one mode of altering in esthetic dentistry. As affected person's esthetic expectancies maintain to growth, dental groups are challenged to perceive a systematic approach for accomplishing oral and facial esthetics with ceramics. Advances in ceramic materials and veneering strategies permit practitioners to repair features and esthetics using conservative and biologically sound methods as well as promoting a long time oral fitness. The esthetic and restorative applications of dental ceramics have expanded and will continue to evolve with time. A 25-year-old male came to Saveetha Dental College and Hospital with a chief complaint of broken, fixed partial denture and compromised esthetic because of discoloration of the tooth. On clinical examination, the patient had generalized enamel fluorosis affecting all the permanent teeth. The case document describes the esthetic management of mild to extreme fluorosis patient with ceramic veneers. Fluorosis is endemic in a few regions of northern India as a result of consuming well water with excessive fluoride content. Bleaching or microabrasion of critically fluorosed teeth are frequently ineffective or gives temporary results while composite resin veneers not only dis-color and wear with time, however quite frequently become chipped or debonded as glazed ceramics retain its color while being wear resistant, noticeably biocompatible and a lifelike esthetics. The esthetic and restorative applications of dental ceramics have expanded and will continue to evolve with time16. However, the clinicians must be sensible in responding to the ever-inflating esthetic needs of the patients, such as every process in dentistry, the achievement of ceramic veneers, and crowns rely on understanding the principals involved in their fabrication and application. The success of treatment may be assured if the dentist follows a described protocol with each patient to ensure that each one factor consisting of smile design, margin placement material, and shade selection are considered. Communication among patient, dentist, and technician is of extreme significance. It is extremely vital to procure an informed consent from the patients before considering such cases. It's also essential to discuss the practical and biological implications of his or her preference. [ABSTRACT FROM AUTHOR]

Onboard image processing systems for a hyperspectral sensor have been developed in order to maximize image data transmission efficiency for large volume and high speed data downlink capacity. Since more than 100 channels are required for hyperspectral sensors on Earth observation satellites, fast and small-footprint lossless image compression capability is essential for reducing the size and weight of a sensor system. A fast lossless image compression algorithm has been developed, and is implemented in the onboard correction circuitry of sensitivity and linearity of Complementary Metal Oxide Semiconductor (CMOS) sensors in order to maximize the compression ratio. The employed image compression method is based on Fast, Efficient, Lossless Image compression System (FELICS), which is a hierarchical predictive coding method with resolution scaling. To improve FELICS's performance of image decorrelation and entropy coding, we apply a two-dimensional interpolation prediction and adaptive Golomb-Rice coding. It supports progressive decompression using resolution scaling while still maintaining superior performance measured as speed and complexity. Coding efficiency and compression speed enlarge the effective capacity of signal transmission channels, which lead to reducing onboard hardware by multiplexing sensor signals into a reduced number of compression circuits. The circuitry is embedded into the data formatter of the sensor system without adding size, weight, power consumption, and fabrication cost. [ABSTRACT FROM AUTHOR]

Two new angled half-beam transformation systems (BTSs) for the reduction of the beam-divergence problem in laser-diode arrays with large smiles are investigated. Both simulations and experiments show that the angle of divergence of laser-diode arrays with the parabola-shaped smile and the S-shaped smile can be reduced by more than 37% and 23% respectively, when two angled half-BTSs are used in front of the laser-diode array. Furthermore, a fiber-coupling module, with a 400 μ m core-fiber and two angled half-BTSs, is fabricated. The optical/optical coupling efficiency increases to more than 85%, which is an improvement by more than 4% over laser diodes that use a full-BTS. [ABSTRACT FROM AUTHOR]
