    Vital tooth bleaching is one of the effective methods for the minimally invasive treatment of discolored tooth. Tooth bleaching techniques is simpler than other dental treatments, but challenges are still encountered in clinical practice. For a successful treatment, some key issues must be addressed through doctor-patient communication before treatment, and personalized treatment plans based on the etiology and difficulty of cases and the planned prevention and management of potential clinical complications during treatment must be considered. This article combines literature review and the author’s clinical experience to discuss clinical strategies for tooth-whitening treatment, aiming to provide a reference for dental bleaching treatment in clinical settings.

    Precise torque expression and stable anchorage control are key points in orthodontic treatment. The concern of patients’ quality of life and oral health during orthodontic treatment is increasing. However, most orthodontic instruments cannot achieve the goals mentioned above. A spherical bracket exhibits advantages in these aspects and mitigates these problems to a certain extent. The spherical surface decreases the ulcer rate. Biofilm formation is inhibited, thereby reducing the probability of gum and periodontal disease occurrence. The bonding failure rate of the spherical bracket is lower than that of other self-ligating brackets by 95%. The lock-hook system is the most innovative aspect of the spherical bracket. The system contains thread, screw, and arch wire systems. The lock-hook system benefits torque expression because of its mitigating function. Furthermore, it improves the stability of anchorage when the lock screw is applied. The arch wire system containing three unique wires (0.152 4 mm×0.635 0 mm, 0.203 2 mm×0.584 2 mm, 0.254 0 mm×0.558 8 mm) can be used by orthodontist to control torque with light force during alignment. Therefore, the spherical bracket has gained increasing interest because of its outstanding performance such as comfort, low bonding failure rate, accurate torque expression, stable anchorage, and light force.

    The restoration space should be fully considered in designing the implant restoration for edentulous patients to accommodate the superstructure of implant dentures and prostheses and select the appropriate restoration method. However, no unified standard exists for the evaluation of restoration space in clinical practice. Mechanical or biological complications of implant dentures occur when the restorative space in the mouth does not match the prosthesis design. This study recommends recording the correct jaw relation retained by natural teeth or old dentures before implant treatment in edentulous patients. The complete digital information of the patient’s oral and maxillofacial region can be obtained using digital technology, and a three-dimensional virtual dental patient model can be constructed. A functional and aesthetically oriented implant restoration plan can be designed according to the measured vertical restoration space and horizontal relationship.
