Rehabilitation of a bilateral maxillectomy defect is highly challenging. Reconstruction with a free-fibula flap provides optimal coverage and allows prosthetic rehabilitation with dental implant-retained prostheses. Deficient height of the fibula bone, especially in the pediatric population or in young adults, may complicate the rehabilitation process. This report describes an interdisciplinary approach to the rehabilitation of a bilateral maxillectomy defect in a childhood cancer survivor using an innovative modification of an existing protocol. Patient acceptance and the quality-of-life outcome were high after secondary placement of bilateral zygomatic and conventional implants in the fibula flap, providing excellent anchorage for a bar-LOCATOR overdenture prosthesis.

Dental implant placement is routinely guided by using 2-dimensional radiographs and thermoplastic surgical guides (CTGs), which may lack accuracy. Three-dimensionally (3D) printed surgical guides (3DGs) have been recommended to improve accuracy. However, they require additional training on specific technology. The current knowledge on indications for CTGs and 3DGs is limited.

Challenges persist with conventional polymethyl methacrylate (PMMA) prosthetic materials and conversion protocols for immediate implant-supported interim restorations. Advances, such as the use of fiber-reinforced composites (FRCs), and novel conversion protocols, such as the Smart Denture Conversion (SDC), may mitigate existing prosthetic complications, yet their impact on flexural strength and mode of failure remains unclear.

Fit accuracy is crucial for the clinical success of implant-supported prostheses. Traditionally, radiographs have been used to assess the marginal fit in 2 dimensions. Three-dimensional (3D) evaluation based on optical scanning techniques requires additional software programs and procedural steps. This article describes an alternative workflow for the rapid verification of the 3D fit of splinted implant-supported crowns. First, the abutments and splinted crowns were positioned onto a printed cast and scanned, with the data exported as a reference. Following the intraoral placement of the abutments and the splinted crowns, an additional scan was made and compared with the reference data to calculate deviations directly within the intraoral scanner. This protocol simplifies the fit evaluation process and provides rapid results, thereby enhancing efficiency and saving time.

Additive manufacturing (AM) and subtractive manufacturing (SM) have been widely used for fabricating resin-based fixed dental prostheses. However, studies on the effects of material type (AM or SM resin) and surface finishing (polishing or glazing) on the surface properties and biofilm formation are lacking.

Accurately transferring the maxillary cast to the articulator is an essential step in most prosthodontics procedures in both digital and conventional workflows. Recently, the use of a smartphone 3-dimensional (3D) scanner-based virtual facebow record has been reported, but its accuracy is unclear.

The ability of artificial intelligence (AI) to accurately forecast the prognosis of dental implants from radiographic images is unclear.

The antimicrobial efficacy of lavender has been well evidenced. However, investigations into its impact on the mechanical properties of denture resins are lacking.

Patient satisfaction and esthetic acceptance are important factors in predicting the success of implant therapy in the anterior maxilla. A standardized esthetic index to evaluate implant esthetic outcomes is still lacking.

Three months after implant placement, difficulty was encountered in unscrewing the healing abutment within the normal torque range (<35 Ncm), resulting in the removal of the implant. Despite all attempts, the implant could not then be separated from the healing abutment. Retrospective analysis of intraoperative photographs revealed the presence of blood or bone debris within the implant before the healing abutment was placed; this was considered to be the likely cause of this phenomenon.

Denture wearers are susceptible to diseases related to denture hygiene and are more prone to develop systemic disease because of poor understanding and awareness of the impact of edentulism on general health.

As the global population ages, tooth loss among older adults has become increasingly prevalent, impacting oral function and overall health. Although removable dentures have been used to improve masticatory function, the long-term effects of denture conditions on mortality are unclear.

Patients with ocular defects often require custom ocular prostheses, which can alleviate esthetic concerns and enhance their overall quality of life. Various techniques such as iris painting and digital imaging have been introduced for fabricating an ocular prosthesis, although these techniques pose several limitations. A cost-effective method of fabricating a custom ocular prosthesis, utilizing easily accessible household materials such as sewing thread and cellulose acetate sheets, is described. The resulting ocular prostheses deliver predictable esthetic outcomes and have been successfully used for over a decade, resulting in favorable patient satisfaction.

Translational studies evaluating the feasibility, accuracy, and safety of semi-autonomous implant robots, from model test to animal experiment and clinical trial, are currently lacking.

A 20-year-old woman with type I hypoplastic amelogenesis imperfecta (AI) experiencing esthetic concerns and hypersensitivity is presented. The treatment was aimed at both functional and esthetic aspects, focusing on complete mouth rehabilitation using a fully digital workflow. In an interdisciplinary approach, a multigene panel analysis was performed. Digital intraoral scans and a face scan facilitated precise virtual planning, guiding minimally invasive preparations. Long-term interim restorations milled from high-performance polycarbonate preceded definitive restorations in translucent zirconia. This approach resulted in a time- and cost-efficient treatment, helped the patient to understand her disease by highlighting the pivotal role of genetics, and demonstrated the success of collaborative dental interventions. A strict recall program will be most important for the long-term success of this patient with AI and a pathogenic frameshift variant in the AMELX gene.

Studies on the significance of intensity on speech production with a tongue prosthesis are lacking, despite this being an important criterion in speech production in patients with total glossectomy.

Dynamic computer-assisted surgical implant placement (dCAIS) facilitates precise implant placement through a real-time tracking system, enabling single-visit treatment. However, an understanding of the learning curve associated with dCAIS in terms of differences between anterior and posterior implant placement is lacking.
