The objective of this study was to evaluate the effect of leukocyte platelet-rich fibrin (L-PRF) on immediate implant stability and recovery. A total of 60 immediate implants were evaluated. After the extraction, using split-mouth design, test sockets were coated with L-PRF (L-PRF+) and control sockets were not (L-PRF-). All the implants were followed for 12 months. Results showed a statistically significant difference between the stability of L-PRF+ and L-PRF- implants at 1 week and at 1 month. Mean marginal bone resorption was higher in the control group at 1 year...

In this prospective study, 15 patients received 15 variable-thread tapered implants placed in fresh extraction sites in the maxillary esthetic zone and immediately were provisionalized out of occlusion. Of the 15 patients, 11 completed their 2-year follow-up. At 2 years, the success and cumulative survival rates were both 100%, and the mean bone level gain was 0.83 mm. Soft tissue assessment showed no zero esthetic scores, improved papilla indices, and low bleeding on probing and plaque accumulation. Overall, the study implants showed excellent hard tissue, soft tissue, and esthetic outcomes, indicating a healthy tissue response in single-tooth extraction sites in the maxillary esthetic zone...

This study evaluated use of a solid-state laser to avoid the flap technique and suturing. An Er:YAG laser was used in 26 consecutive patients referred for osseous crown lengthening in 32 posterior teeth. The distance from the planned restoration margin to the alveolar crest (B) satisfied a 3-mm dentogingival complex. No tissue necrosis and no significant change in the distance from the gingival margin to B or probing depth were detected at 3 and 6 months. Minimally invasive Er:YAG laser surgery decreases the time needed to establish the gingival margin necessary for definitive restoration...

Esthetic implant therapy can be challenging in the anterior maxilla, and meticulous treatment is often required to deliver optimal esthetics. Close collaboration between surgical and prosthetic team members using the novel approach of prosthetic crown lengthening helped camouflage a shallow implant platform location, providing the proper gingival frame for esthetic restorations. This case report presents an interdisciplinary approach that included ridge augmentation, second-stage crown lengthening, and prosthetic soft tissue manipulation to address an implant placed too shallow in the alveolus of an extraction socket...

Today, innovative restorative materials and techniques allow for minimally invasive prosthetic procedures, which are paramount to the preservation of hard and soft dental tissues. An integrated approach combining dental and esthetic medical therapies could be useful to improve the quality of life of patients, improving function, esthetics, and self-confidence. Oral esthetics depends on several variables, including tooth visibility and proportions as well as healthy gingival tissues. Proper integration between teeth and periodontal tissues plays an important role in esthetic success, which is mainly represented by an appealing smile...

This article presents a clinical protocol to reconstruct two accidentally damaged maxillary central incisors using composite resin material and a fractured tooth component. A patient was referred to the clinic with fracture of the two maxillary central incisors. Clinical examination revealed that both teeth were fractured in the middle third of the crown and that the fractures involved enamel and dentin with no pulp exposure. The patient had also suffered a lower lip laceration. When the lip was evaluated, a fractured fragment of the maxillary right central incisor was found inside the wound...

Primary wound closure and uneventful early wound stability over the biomaterials are the most critical elements of successful periodontal regeneration. Yet the surgical elevation of the interdental papilla to access deep and wide intrabony defects entails an impairment of the papillary blood supply that can result in difficult healing due to a lack of primary closure in the early healing period. This negative event might complicate the healing process, favoring bacterial contamination. A novel modified tunnel surgical technique designed to maintain the integrity of the interdental papilla is presented in this article, with the aim of providing an optimal environment for wound healing in regenerative procedures...

Medical and dental histories, clinical examination, study models, and photographs provide the data for a proper diagnosis and the treatment plan for esthetic dentistry. However, they do not offer all the information necessary to analyze the smile and create harmony with the lips and face without excessive intraoral adjustments. Dentolabial parameters vary according to lip dynamics and are influenced by both a static posed smile and a smile in motion as captured in video. This article describes a documentation protocol using smartphone videos to improve the analysis, smile design decisions, and elaboration of a 2D smile frame that will guide the 3D digital smile design project...
