Objectives: To demonstrate the implementation of a digital workflow for the rehabilitation of a terminal dentition patient with complete-arch implant-supported prostheses.

Clinical Considerations: A virtual patient-oriented workflow can facilitate interdisciplinary treatment planning, improving the synergism between surgical and prosthetic procedures. Digital technologies assisted the acquisition of prosthetic information and optimized dental implant placement, provisional restoration fabrication, and delivery of definitive prostheses.

Contemporary oral tissue engineering strategies involve recombinant human growth factor approaches to stimulate diverse cellular processes including cell differentiation, migration, recruitment, and proliferation at grafted areas. Recombinant human growth factor applications in oral hard and soft tissue regeneration have been progressively researched over the last 25 years. Growth factor-mediated surgical approaches aim to accelerate healing, tissue reconstruction, and patient recovery.

Diverse surgical approaches, such as resective, reconstructive, and combined therapy, have been proposed for peri-implantitis treatment. A resective surgical approach with an adjunctive modified implantoplasty refers to the modification of the implant body into a constricted area to mimic a 'waist' silhouette. This modified technique forms an adequate concave smooth area that may favor the outcomes of resective surgical therapy for soft tissue adaptation, biofilm control, and possible peri-implant bone gain over the long term.

Purpose: To describe a novel, noninvasive, intraoral optical scanning-based approach for characterising the buccolingual profile of peri-implant tissues using a 3D surface defect map.

Materials And Methods: Intraoral optical scans of 20 isolated dental implants with peri-implant soft tissue dehiscence in 20 subjects were captured. The digital models were then imported into image analysis software, where an examiner (LM) performed a 3D surface defect map analysis characterising the buccolingual profile of the peri-implant tissues in respect to the adjacent teeth.

Peri-implantitis is caused by a bacterial challenge; therefore, anti-infective treatment strategies should be employed to manage the disease. As nonsurgical approaches demonstrate limited efficacy in most cases of peri-implantitis, surgical interventions are often required. Treatment outcomes improve following access flap surgery, with or without adjunctive resective and/or augmentation measures.

Purpose: To evaluate the influence of macrophage expression and polarization on the effectiveness of surgical therapy of peri-implantitis over a 6 month follow-up.

Methods: A total of fourteen patients (n = 14 implants) diagnosed with peri-implantitis underwent access flap surgery, granulation tissue removal, implantoplasty, and augmentation at intra-bony components using a natural derived bone mineral and application of a native collagen membrane during a standardized surgical procedure. Granulation tissue biopsies were prepared for immunohistochemical characterization and macrophage polarization assessment.

Background: The social diversity, heterogeneous culture, and inherent economic inequality factors in Latin America (LA) justify conducting a comprehensive analysis on the current status and future trends of peri-implant diseases and conditions. Thus, the aim of this Delphi study was to predict the future trends in the diagnosis and treatment of peri-implant diseases and conditions in LA countries for the year 2030.

Methods: A Latin American steering committee and group of experts in implant dentistry validated a questionnaire including 64 questions divided into eight sections.

Purpose: To assess the prevalence of peri-implant diseases (ie, peri-implant mucositis and peri-implantitis) in patients rehabilitated with full-arch, implant-supported restorations.

Materials And Methods: A search protocol was developed to answer the following focus question: What is the prevalence of peri-implant diseases in edentulous patients rehabilitated with implant-supported fixed or removable restorations? RCTs, controlled clinical trials, and prospective studies with at least 12 months of follow-up and a minimum of 10 patients having at least one edentulous arch were searched.

Results: A total of 18 studies (3 RCTs, 1 nonrandomized controlled trial, and 14 prospective studies) were included.

Bone defects resulting from infections, tumors, or traumas represent a major health care issue. Tissue engineering has been working togehter with medicine to develop techniques to repair bone damage and increase patient's life quality. In that context, scaffolds composed of bioactive ceramics have been explored, although their poor mechanical properties restrain their clinical applications as highly porous structures.

Implantoplasty has been claimed as a promising strategy to treat peri-implantitis and prevent progressive peri-implant bone loss. Consequently, the aim of the present case series is to exhibit the clinical outcomes of a 3-year-follow-up resective and implantoplasty therapy applying a novel platform-switch concept to preserve peri-implant tissue integrity and counteract progressive bone loss. Four patients who underwent dental implant therapy and were diagnosed with peri-implantitis were treated through access flap surgery, a modified implantoplasty, bone recontouring, and surface decontamination.
