Purpose: This cross-sectional study aimed to identify and characterize the pathway for appropriate placement of four zygomatic implants in the severely atrophic maxilla and to group the anatomical variations of the osteotomy trajectory for anterior zygomatic implants. Materials and Methods: CBCT images of patients presenting indications for the use of four zygomatic implants to withstand a maxillary rehabilitation were reviewed. Cross-sectional planes corresponding to the implant trajectories, designed according to a zygoma anatomy-guided approach for implants placed in the anterior and posterior maxilla, were assessed separately. The relationship of the implant osteotomy trajectory with the correlated residual alveolar bone, nasal and sinus cavities, maxillary wall, and zygomatic bone anatomies was established. Results: The study population included 122 globally recruited patients, with 488 zygomatic implants, 244 of which had their starting point on the anterior incisor-canine area and 244 on the posterior premolar-molar area. The anatomy of the osteotomy path designed for the anterior implants ("A") was named and grouped into five assemblies from zygomatic anatomy-guided ZAGA A-0 to A-4, representing 2.9%, 4.5%, 19.7%, 55.7%, and 17.2% of the studied sites. Percentages for posterior implant ("P") trajectories of the osteotomy were grouped and named as ZAGA P-0 to P-4, representing 5.7%, 10.2%, 8.2%, 18.4%, and 57.4% of the sites, respectively. Approximately 70% of the population presented anatomical intra-individual differences. Conclusion: The trajectory of the zygomatic implant followed different anatomical pathways depending on its coronal point being anteriorly or posteriorly located, which justifies a new zygoma anatomy-guided approach classification for anteriorly placed zygomatic implants. Topographic characteristics of the anatomical structures that are cut by an anterior oblique plane joining the lateral incisor-canine area to the zygomatic bone, representing the planned anterior osteotomy path in a quadruple-zygoma indication, have not been previously reported. Adaptation of surgical procedures and implant sections/designs to individual patients' anatomical characteristics is essential to reduce early and long-term complications. [ABSTRACT FROM AUTHOR]

Vertical bone augmentation techniques are more invasive than other procedures, and success rates often vary according to the surgical expertise of the clinician. As a result, there has been a trend over time towards minimally invasive treatment options in implant dentistry. This article discusses a "graft less" treatment philosophy that emphasizes the use of less-demanding augmentation techniques for the purpose of placing shorter implants in atrophic posterior sites, avoiding more complicated procedures for implant placement. In the posterior maxilla and mandible, the use of short implants (< 8.0 mm) can reduce the need for vertical bone grafting. Patients often prefer this strategy over more complex procedures that can cause complications, increase morbidity, and require longer treatment times with higher costs. When inadequate available bone is present for implant placement, planned bone augmentation procedures may be performed for the purpose of placing shorter implants; these procedures are less demanding, less invasive, and more predictable, allowing long-term outcomes for the implant-supported restoration.

The patient treatment described in this case report demonstrates management of a failing maxillary first molar utilizing an immediate loading approach. Following extraction, the site was successfully managed with socket grafting (ridge preservation) and allowed to heal prior to implant placement. A Straumann® TLX implant was placed using a guided approach and restored using CAD/CAM. [ABSTRACT FROM AUTHOR]

Various approaches have been utilized in the past for immediate implant placement in the esthetic zone. When an immediate approach is indicated, static computer-aided implant surgery (S-CAIS) could allow for precise implant positioning, thus contributing to an adequate tridimensional position for a predictable treatment outcome. This article discusses the planning phase and treatment sequence for an esthetic restoration, including a crown-lengthening procedure, a single tooth replacement based on an immediate implant, immediate restoration using S-CAIS, and bone and connective tissue grafting. Definitive restoration of the implant and adjacent tooth is also described. [ABSTRACT FROM AUTHOR]

The article discusses the technical aspects and applications of digital impressions in dentistry, with emphasis on orthodontics. It explores the development of digital impression systems. It states that these systems include Computer Aided Design/Computer Aided Manufacture (CAD/CAM) systems and dedicated three-dimensional digital impression systems (3D).

Although there are difficulties with using intraoral scans for implant-supported complete-arch fixed dental prostheses (ISCFDPs), several commercially available systems have become helpful in simplifying the treatment process in the prosthetic phase. These systems help patients move from interim ISCFDPs to receiving definitive prostheses in just three clinical visits. This clinical report summarizes the indications, benefits, and limitations of the four systems. The information provided in this report about the digital prosthetic workflow of ISCFDPs aims to help clinicians make well-informed choices and improve treatment results. With digital technologies advancing, refining these tools and protocols, and validating research is crucial for continued evolution in the field., (© 2024 The Author(s).

3D-printed shell complete dentures generated from a scan of the patient's existing prostheses can simplify and expedite the surgical planning and interim restoration design for complete arch rehabilitations. Three patients were rehabilitated with endosteal implants, and interim restorations were generated from the contours of the 3D-printed shell complete dentures used as diagnostic aids. This case series report presents the recommended protocol and its clinical progression, in addition to clinical and radiographic images of the treatment outcomes., (© 2024 The Author(s).
