Ridge defects are a very common finding after tooth extraction. Recent literature has shown that the pattern of bone and soft tissue remodeling can obtain up to 50% of the original volume. Many different surgical approaches have been proposed over the years to correct ridge defects, but the results have often been inconsistent or difficult to reproduce on a daily basis. For some time, surgeons have relied on the guided bone regeneration (GBR) technique, taking advantage of a barrier membrane to protect the blood clot, combined with different combinations of autogenous bone and bone grafts from various sources. If some kind of understanding has been reached and certain guidelines adopted for the treatment of horizontal defects, those for tridimensional and vertical defects still present a challenge. About a decade ago, a new biomaterial became available on the market - a membrane made of collagenated porcine bone called cortical lamina - which proved to be reliable and easy to handle for both horizontal and vertical defects. The aim of this article is to review the current literature on the topic and to discuss the material in its three forms through the presentation of three patient cases of differing complexity, each with its unique indications and characteristics.Soft tissue augmentation techniques have become crucial to improve tissue volume and quality in periodontal and peri-implant dental surgery. A clinician's knowledge of the principle of flap design and management is a key aspect for treatment success, particularly in the esthetic area. Implant failures in the esthetic area are one of the most challenging situations in modern dentistry, and often cases have to be resolved through multidisciplinary treatments in which soft tissue management and patient selection are substantial aspects. Ridge defects are commonly treated with bone regeneration-like techniques in order to place implants. However, in young patients, where implant treatment should be carefully selected, fixed prosthetic restorations in combination with mucogingival surgery could be a successful option to enhance esthetics. The present case report describes a treatment approach for implant failure in the esthetic area in young patients, consisting of a combination of connective tissue platform technique, resective surgery, and a Maryland bridge restoration.
The combination of partial edentulism and a worn anterior tooth in the esthetic zone can be a challenge for the dentist. This clinical situation requires extensive knowledge of soft and hard tissue management, surgical planning and execution for implant therapy, and conservative tooth preparation with ideal bonding protocols for the tooth-supported prosthesis. Moreover, an optimal selection of the final restorative materials is imperative to manage occlusal forces and fulfill the patient's esthetic demands.

The patient presented with partial edentulism on site 11, a worn incisal edge, and facial defects on tooth 21. Minimally invasive implant therapy for site 11 was performed with a papilla-sparing flap design that only included the edentulous site, and the soft tissue contouring was started for an immediate provisional restoration. A suturing technique was executed that aimed at maintaining an interproximal papilla. Conservative veneer preparation was performed on tooth 21 in order to bond the restoration to the enamel structure. Final restorations included a custom abutment with a lithium disilicate fused to zirconia crown for the implant on site 11 and a lithium disilicate veneer on tooth 21.

A well-planned single implant and a ceramic veneer restoration was able to fulfill the patient's esthetic expectations. The selection of materials for the final restoration was crucial to manage the occlusal forces and to mimic the shade and shape of the adjacent teeth.

The emphasis is on the understanding and application of the biologic factors and dental technology that influence treatment outcomes. The authors examine the exciting new world of digitalization of dental procedures that has transformed esthetic dentistry, dental technology, and surgery. The digital workflow makes it possible to attain excellence in many kinds of dental restorations, providing high quality while maintaining a very natural-looking appearance. The newest developments in the field of digital systems allow for greater predictability and precision of results as well as more accuracy, which in turn allows for better design quality. The duration of dental treatment and dental technology has also been reduced due to digitalization. Transitioning from an analog to a digital workflow requires a paradigm shift. The techniques to improve the daily workflow in practice and in the dental laboratory integrate advanced CAD/CAM technologies, combining 3D-printed models and high-end esthetic dental restorations in ceramics. An interdisciplinary approach, detailed in this article, is key to optimal case management.The socket-shield technique shows promising results in the esthetic zone. It is a technically challenging procedure but is effective in maintaining the buccal plate after tooth extraction and avoiding tissue collapse. Therefore, it could be considered a valid option in the immediate implant scenario. A careful shield preparation and handling are paramount for the success of the treatment and to minimize complications. Raising a flap can improve visibility and simplify the procedure. This article reports on a case in which a small crestal approach is used to visualize the root and the buccal plate, combined with a buccal semilunar flap, to gain access to the apical area. This surgical management is especially indicated when long roots are involved, in order to determine the correct axis for cutting and sectioning the root and to remove the apex if conventional drills are not long enough. buy G007-LK Possible esthetic complications of raising a flap are also discussed.
