Accurate working impression is an essential requirement for the fabrication of implant prosthesis, and digital impressions have recently become more popular. In this case report, a completely digital workflow is introduced for the fabrication of three single-unit screw-retained implant crowns on the posterior maxilla by a dental student, under supervision. This approach involved the use of an intraoral scanner to capture a digital impression of the three implants and their surrounding mucosa, the opposing arch, and occlusion. The use of intraoral scanners and digital impressions illustrated an efficient and patient-friendly method of capturing the necessary data to fabricate a well-fitted prothesis. The aim of this case report is to examine a fully digital approach in the production of multiple single-unit implant crowns.

Aim: To systematically review the literature on the surgical and non-surgical methods for managing peri-implantitis.

Materials and methods: An electronic search for randomised controlled trials published between 2019 and 2023 in the English language was performed with the Medline/PubMed database according to the guidelines of Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The specific search terms were "periimplantitis", "non-surgical treatment", "surgical treatment" and combinations of these terms.

Results: The initial search yielded 2,704 relevant articles. Most of these articles were excluded based on publication type and year. At this stage, only two articles were excluded from the study because they were not written in English. Of the remaining 98 articles, seven were eliminated because the full text could not be accessed, and the others were excluded because their study topics and types were not within the scope of this review. Six out of the 51 studies, whose full texts were assessed for eligibility, were further excluded. Finally, 45 articles that met the inclusion criteria of this review were evaluated.

Conclusion: Personalised and evidence-based approaches in the treatment of peri-implantitis are at the forefront in achieving the long-term success of peri-implantitis therapy. Further evidence is needed for the outcomes of surgical or non-surgical peri-implantitis treatment methods applied alone or with adjunctive therapies.

Abutment contours, position, tissue thickness, and volume are all key parameters for the successful restoration of implants in the aesthetic zone. This is particularly true for patients with high smile lines and high aesthetic expectations. This narrative review will provide a synopsis of the known science of implant abutments and peri-implant tissues in this area and cover specialised techniques, materials, and protocols to improve outcomes with increased predictability. Special attention will be given to the use of provisionals and custom healing abutments for the preservation and shaping of the peri-implant tissues.

The number of dental implants placed and restored every year is increasing across the world. However, there has been an increase in the number of reports with implant-related surgical complications in which the inferior alveolar nerve injury is the most serious one. This surgical problem can be avoided by using cone beam computed tomography (CBCT), three-dimensional (3D) implant planning software, and computer-aided design and computer-aided manufacturing (CAD-CAM) technology such as stereolithographic surgical guides. The objective of this report is to present the clinical and radiologic findings of a female patient with the injury of inferior alveolar nerve after implant insertion where CBCT has not been used prior to implant placement.

Conventional complete denture wearers often complain of lack of stability and overall discomfort with their prostheses. The advent of dental implants and advanced prosthetic methods have greatly improved this struggle for edentulous patients. The utilisation of computer-aided design and computer-aided manufacturing (CAD-CAM) technology has only further enhanced the capabilities of dental practitioners to rapidly and accurately restore edentulism. This report details the advantages of using CAD-CAM technology compared to analogue methods for titanium framework design and fabrication. It discusses the decrease in framework distortions, ease of communication with laboratories, and amount of time saved from the implementation of this technology. The results of this clinical report suggest that fixed dental prostheses with titanium frameworks fabricated using the software and scanner presented in this report fit accurately and may be a viable option to restore edentulous arches.
