Indications: Adult teeth misalignment, tetracycline teeth, fluorosis, yellow teeth, tooth loss, tooth gap, malocclusion, etc. Economical, healthy, natural and beautiful, will be the future development trend of dental aesthetic restoration. 1.Minimally invasive or non-invasive: it can preserve the tooth tissue to the maximum extent and cause minimal or no adverse stimulation to the gum and periodontal tissue. 2.Saving time: the number of visits is small, and most cases can be completed in one visit. 3.Immediate effect: operated directly by the doctor, avoiding many intermediate links, the effect is more reliable. Reasonable adjustments can be made according to the patient’s wishes. 4.The hardness of the resin material will not cause damage to the jaw teeth. 5.Economic: resin material is commonly used in dentistry, and the treatment cost is lower than indirect restoration. 6. In line with modern orthopedic concepts: sufficient tissue space is left for repetition or further cosmetic restoration. As an organ of the most prominent part of the face, teeth can reflect personal quality cultivation and hygiene concept. Dental function and its cosmetic role, destined to dental cosmetic restorative treatment is a process and boutique nature that must be carefully designed and operated. As the saying goes, “If it doesn’t rain across the road, the wind will be different for a hundred miles”. With the increase in aesthetic requirements of patients, and with the advances in material science and dental clinical filling sculpture technology, it has been possible to give a good answer to these questions by preserving as much tooth tissue as possible at the beginning of the treatment, thus avoiding destructive dispositions such as extractions and grinding of teeth that cannot be recovered irretrievably. For a wide range of patients with indications, minimally invasive cosmetic dental treatment can be performed using nano-resin stacking restorative techniques, i.e., to obtain good cosmetic dental results, while meeting the functional needs of the mouth and ensuring the requirements of dental gum health. In the past, the resin filling effect left a not-so-good impression, with a rough and lusterless surface, easy to fall off and discolor, and could not be called cosmetic dental restoration. At the same time, due to poor strength, it could not perform dental functions such as cutting and chewing food, so it could only be used for simple filling in clinical practice. At present, with the continuous progress of material science, resin materials can fully meet the oral function requirements of aesthetics and high mechanical strength with the changes of resin filler content, shape and other components in terms of mechanical strength and gloss. Advances in resin material science have dramatically improved the effectiveness and durability of direct resin cosmetic restorations, especially the immediate and minimally invasive cosmetic effects, bringing unexpected surprises to patients, relieving the fear of damaging the teeth and gums and restoring a confident smile. Minimally invasive cosmetic dentistry is a holistic treatment process that organically combines minimally invasive treatment with dental aesthetics, while taking into account the patient’s psychological, health, functional and aesthetic aspects to ultimately achieve the goal of improving the patient’s smile and meeting the psychological expectations of both the doctor and the patient. This process encompasses the conventional dental treatment process and aims to give the patient the most appropriate aesthetic treatment in all aspects of the patient’s oral health. The two most important principles are the preservation of as much tissue structure as possible and the aesthetic restoration. The key points to ensure success are the doctor’s fine treatment operations and the quality of the materials used. Successful cosmetic restorations can achieve the following aesthetic results: strength with the ability to perform normal oral functions, harmonious morphology and alignment relationships, and harmonious color and brightness. In view of the stability of the quality of the material, then the level of skill of the doctor is particularly important, especially the mastery of the shaping technique in a short period of time. Resin veneers are recognized and respected by people who already know the technology due to the following obvious advantages
