Aesthetics are one of the primary goals of restorative care. Teeth that are traumatized in the anterior maxilla usually avulse or require extraction due to fractures. Rehabilitation is challenging in such a therapeutic state since it presents several anatomical and aesthetic issues. There are circumstances in which traditional implant placement is problematic. There must be enough bone for implant placement to be uneventful and successful. Other surgical therapies may be necessary in addition to implant placement for certain operations, such as extensive grafting, direct or indirect sinus lifts, and nerve lateralization. Certain procedures are required for these operations but are not always achievable. Because single-piece basal implants provide immediate temporization and loading while receiving adequate anchoring from the basal cortical bone, they have been extensively used to rehabilitate resorbed ridges. This case report demonstrates the placement of the basal implant in the anterior zone.

An optimal esthetic result is essential for an implant-supported restoration in the anterior zone. In the esthetic zone, providing immediate interim restorations following implant surgery has been proposed as a reliable and desirable treatment approach. A well-contoured interim restoration following implant placement minimizes hard and soft tissue changes in the peri-implant zone. This in turn has the potential to enhance the esthetic outcome and, therefore, patient satisfaction. Multiple prosthetic and surgical aspects need to be carefully planned and executed to achieve the intended final result. This is a report describing the steps involved in recontouring the gingiva to achieve an optimal emergence profile following the immediate loading of a single implant in the esthetic zone.

Restoring periodontally compromised teeth in esthetic zones through dental implant rehabilitation poses significant challenges due to the loss of supporting tissues. This case report describes a staged treatment strategy designed for a 48-year-old woman with advanced chronic periodontitis of the esthetic zone. This approach combined various advanced techniques, including periodontal regeneration, orthodontic implant site development with labial root torque, guided bone regeneration, and soft tissue augmentation. The innovative orthodontic implant site development with labial root torque technique was employed to harness healthy palatal periodontal ligament cells by strategically applying labial root torque in the horizontal labial-palatal direction. This technique uses healthy palatal periodontal ligament cells, which benefits overall periodontal health. The procedure involved gradually shifting hopeless teeth at a rate of 2 mm per month using nickel-titanium wires, thereby maintaining overcorrection for 2 months before extraction. Following successful orthodontic implant site development with labial root torque, the next phase involved guided bone regeneration using a honeycomb-structured titanium membrane. This set the stage for implant placement 6 months later, ensuring a stable foundation for subsequent prosthetic intervention. Soft tissue augmentation was then meticulously performed using an artificial collagen dermis infused with fibroblast growth factor-2, contributing to the overall esthetic outcome. Final prosthesis integration revealed a harmonious blend with the adjacent teeth and gums, underscoring the success of this multidisciplinary approach. This case report provides valuable insights into severe periodontitis in the esthetic field. Our findings highlight the importance of continuously researching and improving procedures for optimal patient care.

This case report presents a challenging case of catastrophic failure of a fixed partial denture involving fracture of the prosthesis as well as supporting implants and teeth. The use of robotics facilitated efficient and successful restoration of the patient\'s dentition. After extraction of 2 fractured teeth and 1 fractured implant, 2 new implants were placed with haptic guidance from robotics, which allowed for stable osteotomies and high initial implant stability quotients. Due to the patient\'s tremors and heavy occlusal forces, restoration was delayed to allow the surgical site to heal, and the patient received a provisional partial denture. With subsequent placement of the final restoration, the treatment was fully completed in 4.5 months and required only a single surgical procedure. The use of haptic robotics in this case allowed for accurate planning, spacing, and placement of screw-retained implants with an optimal arch, leading to the best long-term outcome for the patient.

This case series assessed the efficacy of Orthodontic Implant Site Development with Labial Root Torque (OISD-LRT) as a nonsurgical technique for addressing labial bone deficiencies in seven patients. The procedure involved strategically placing a multi-bracket of 2-3 mm apically on the hopeless teeth, gradually shifting them with Ni-Ti wires at the rate of 2 mm per month and maintaining overcorrection for 2 months before extraction. OISD-LRT consistently augmented tissue for flapless guided implant surgery, with an average treatment duration of 404Å}311.7 days. Cone-beam computed tomography (CBCT) scans at various stages revealed increases in both vertical and horizontal bone dimensions, especially in the sockets with complete labial bone loss. Despite inevitable post-extraction reductions in bone height and width, sufficient dimensions were maintained to ensure long-term implant stability. This case series highlights the effectiveness of OISD-LRT as a valuable method for horizontal bone augmentation, particularly in patients with labial bone deficiency. This approach provides a robust foundation for subsequent implant placement, showcasing its success in addressing challenging anatomical conditions and contributing to the broader field of implant dentistry.

This clinical report explores the effectiveness of dental implants for rehabilitating fully edentulous arches, with a focus on the all-on-six treatment approach. Implant-supported fixed restorations, particularly using six implants, are presented as an expected and cost-effective solution for the rapid repair of the edentulous patient, avoiding the need for bone grafting. This report details the successful rehabilitation of a patient\'s completely edentulous arches using the all-on-six concept, highlighting the meticulous planning and execution involved. It concludes that precise diagnostic and implant planning, along with thorough attention to all the features, is crucial for successful implant-supported fixed prostheses, with the all-on-six concept offering improved clinical and radiological outcomes for atrophied maxillae.

BACKGROUND: The association of the periodontium with the fixed prosthesis is the basis of prosthetic rehabilitation. This prospective case series aimed to evaluate periodontal health through the relation between periodontal/peri-implant disease progression and the use of fixed partial dentures (FPDs).
METHODS: Probing depth (PD), clinical attachment level (CAL), gingival index (GI), and plaque index (PI) on either teeth or implants were evaluated at up to 25-year follow-up and compared with the baseline. Statistical analysis was performed using the Kaplan-Meier test (p⟨0.05).
RESULTS: The prospective evaluation showed that the patients maintained adequate periodontal health. Failure (severe periodontal stages) occurred in 12.5% of patients. The survival rate for 107 teeth/implants was 80.48%. The comparisons for clinical parameters revealed no statistically significant difference (p⟩ 0.05). At T1, the measurements for anterior and posterior regions, respectively, were PD =2.7mm and 3.1mm; CAL= 3.3mm and 3.6mm; GI=0.5 (both regions); and PI=0.79 and 0.62. Periodontal/peri-implant disease progression did not relate to the use of prostheses.
CONCLUSIONS: Patients with more frequent follow-up appointments and lower GI and PI showed periodontal health for longer periods. Patients with different oral hygiene levels present different periodontal disease progression. Periodic hygiene control and motivation are vital factors for extensive oral rehabilitation success.

The insertion of foreign bodies underneath the skin of the penis is commonly referred to as \"pearling.\" Although rare, there are case reports that describe acute complications such as infection and damage to surrounding penile neurovascular structures; however, there is a paucity of data describing long-term complications and surgical management of such cases. A 43-year-old male presented with a penile abscess secondary to \"pearling\" five years after insertion. His abscess was drained and selected foreign objects were subsequently removed during a simultaneous circumcision procedure. This report describes a case in which surgical removal of penile foreign bodies was performed during a circumcision without the need for additional incisions. The case is unique in that it details a complication five years after initial insertion with microbiological data to guide adequate treatment.

The case in this study had moderate hypodontia, with both lower lateral incisors and the lower-left second premolar missing. A Class II division 2 relationship with severe crowding in the upper arch and a traumatic deep bite over a skeletal I base complicated the occlusion.
The plan was to extract the upper first premolars to relieve upper arch crowding and the lower-left impacted second premolar to preserve the bilateral class I molar relationship. A class I occlusal relationship was achieved through space opening in the lower lateral incisors region and space closure in the upper and lower premolars regions.
The use of orthodontic screws for bite opening and anterior segment retraction, in conjunction with bi-metric slot size selection in bracket prescription, was effective in controlling incisor inclination and interincisal angle. The use of an implant fixture before beginning the finishing stage allowed for a reduction in total treatment time and facilitated the provision of the final prosthesis before debonding the case. As a result, the patient was able to receive a satisfactory occlusion on the day of debonding.
This case of moderate hypodontia was successfully resolved by combining space closure and space opening effectively. To solve the arch problems in such Class II division 2 cases with severe crowding, extractions were required. To complete the case, this was combined with intrusive and retractive mechanics. In hypodontia cases, implants are an excellent choice for both aesthetics and functional restoration.

BACKGROUND: With periodontal disease having an increasing incidence, mandibular free-end edentulism caused by periodontitis is clinically more common. Finite element analysis and clinical case reports were used to evaluate the influence of different designs on the load distribution of implant prosthesis in mandibular posterior free-end edentulism.
METHODS: A finite element model of a mandible with posterior free-end edentulism was established. Considering the implant position and selection of single crown repair or splint repair, four designs were conducted including model A: 3435 × 37(four-unit fixed bridge supported by three implants, implant positions were 34, 35, 37); model B: 34,35 × 37, (34: a single implant crown) (35 ×37: three-unit fixed bridge supported by two implants, implant positions were 35, 37); model C: 34 × 3637(four-unit fixed bridge supported by three implants, implant positions were 34, 36, 37); and model D: 34 × 36, 37(37: a single implant crown)(34 ×36: three-unit fixed bridge supported by two implants, implant positions were 34, 36). Stress distribution and the Von Mises stress value of the implants, the crown and the bone around the implants were analyzed at vertical and 45° inclined load.
RESULTS: Stress in the cortical bone was mainly concentrated around the implant neck, and maximum Von Mises stress (MVMS) of the four models was 11.6-16.1 MPa at vertical load and 61.74-96.49 MPa at 45° inclined load. Stress in the cancellous bone was concentrated around the implant base, and MVMS of four models was 3.075-3.899 MPa at vertical load and 5.021-6.165 MPa at 45° inclined load. Stress of the restoration crowns was mainly concentrated in the connector of the bridge, and MVMS of four models was 23.38-26.28 MPa at vertical load and 53.14-56.35 MPa at 45° inclined load. Stress of the implant interface was mainly concentrated on the surface of the smaller implants near the bridge, and MVMS of four models was 21.12-33.25 MPa at vertical load and 83.73-138.7 MPa at 45° inclined load.
CONCLUSIONS: There was favorable stress distribution of the four models at vertical load and 45° inclined load. Design of a three-unit fixed bridge combined with a partial crown may be an available option for devising patient treatment plans with mandibular free-end edentulism.
