Introduction: Fixed prostheses on dental implants are made of various materials and designs. The most frequent mechanical complications are delamination and wear of the materials. Objective: To demonstrate the advantages of prostheses with milled metal occlusal surfaces to reduce mechanical complications. Case presentation: Two full-arch fixed prostheses on implants were planned to treat an 80-year-old patient whose teeth presented periodontitis and caries. CAD/CAM technology with milling technique was used in the structure. Once the polished prostheses were placed in the patient's mouth, it was observed that when she smiled, the milled metal occlusal surfaces were imperceptible, in addition to reducing the risk of delamination and providing a better passive fit. Conclusions: CAD/CAM technology allows obtaining milled metal occlusal surfaces that favour the reduction of mechanical complications, and a better passive adjustment at competitive costs.

Minimally Invasive Restoration of Interdental Spaces in a Young Patient

Introduction: The shape, position, colour of the teeth and their relationship with the gingival tissues determine the harmony of the smile. The flowable resin injection technique in combination with occlusal and aesthetic prosthetic concepts offers a conservative approach to restoring teeth and improving their proportion, shape and contour. Using a silicone key, a diagnostic wax-up can be transferred to the clinical situation in a predictable manner, is repairable, and has a reported success rate of 3 to 7 years. Furthermore, compared to conventional ceramic veneer procedures, the injected resin technique allows for minimal wear of the tooth structure, is considerably more economical and requires less time. Objective: To describe a treatment followed to close interdental spaces with a minimally invasive technique in the anterior maxillary sector (13-23). Case presentation: A 16-year-old female patient attended the Prosthodontics Specialty clinic referred by the Orthodontics Specialty to close interdental spaces. Unsatisfactory aesthetics, wide interdental spaces, high smile and caries were identified. The periodontal diagnosis was altered passive eruption and maxillary exostosis. The treatment was divided into three phases: First phase, Hygienic, coronal scraping was performed in the 4 quadrants. Second phase, Surgical, the crown lengthening of teeth 16 to 26 was performed and the bone exostosis was removed from them. Third phase, Prosthetics, 10 veneers were made using the injected resin technique. Conclusions: Multidisciplinary management is essential for a good diagnosis and execution of appropriate treatment plans. In this case, the interdental spaces were closed with minimally invasive restorations with adequate contours and proportions and gingival exposure was reduced through surgery.

Introduction: Current dentistry offers different aesthetic alternatives with minimal invasion. For patients seeking to improve dental appearance, the preparation of aesthetic veneers is a good alternative in the case of short clinical crowns, dental re-anatomization and color changes. Objective: To show the interdisciplinary treatment of a patient to improve the aesthetic conditions of the anterior maxillary sector in a minimally invasive manner. Case Presentation: A 21-year-old female patient attended a dental evaluation appointment. During the examination the following was observed: diastemas in the upper anterior teeth and short clinical crowns. After the smile design was carried out, aesthetic crown lengthening of teeth 13 to 23 was performed and then oral rehabilitation began. Conclusions: When planning clinical cases in which dental aesthetics are involved, it is important to look for different options that together achieve good aesthetic and functional results. In this patient, dental aesthetics were achieved with maximum preservation procedures for dental tissues.

Curing light: An important device in adhesive dentistry

Abigailt Flores-Ledesma, Jacqueline Adelina Rodríguez-Chávez — Fri, 07 Mar 2025 00:00:00 -0600

Today's dentistry, in terms of operative and rehabilitative dentistry, focuses on adhesive dentistry. Since the introduction of light-curing resin-based materials such as composite resins, adhesive systems, resin cement, and orthodontic adhesive systems, the use of curing lights has expanded. So curing light is a dental device of prime necessity. The selection of curing lights should be based on their characteristics that directly influence the polymerization process.
