Abstract:

Dental implants are essential for the prosthetic rehabilitation of edentulous patients, requiring adequate bone volume and density for osseointegration and load support. The posterior region of the maxilla, commonly deficient in bone quality and quantity, represents a clinical challenge. This case series reports an analysis involving 69 dental implants in the atrophic maxilla of nine patients. The procedures adopted combined alloplastic hydroxyapatite grafting and leukocyte platelet-rich fibrin (L-PRF) applied to the alveolar ridge and maxillary sinus lift.

Abstract:

The rehabilitation of the atrophic maxilla is a challenge in implant dentistry, requiring effective and minimally invasive techniques. The All-on-Four technique is a well-established alternative, characterized by the placement of four implants in the anterior and posterolateral regions of the edentulous maxilla, providing support for a full-arch implant-supported prosthesis. This approach reduces costs, morbidity, and treatment time. In cases of poor bone quality, adapting the protocol by including pterygoid implants—referred to as the hybrid All-on-Four technique—offers an effective and predi

Abstract:

Retention, stability and support are the most fundamental and basic principles on which the success of an entire denture relies on. However this factor is often compromised in cases of resorption. Residual ridge resorption is the reduction in size of the bony ridge under the mucoperiosteum. The rate of resorption in mandibular arch is at an increased rate as compared to the maxillary arch; but severely atrophic maxillae with large inter-ridge distance often pose a clinical challenge during fabrication of a successful maxillary complete denture because of the increased weight of the denture, re

Rehabilitation of atrophic maxilla still remains a challenge. Fixed implant-supported restorations have become more predictable in the last years; nevertheless, technical and biological complications still occur. Removable overdenture fully supported by a CAD/CAM titanium bar seems to be a viable treatment option for the rehabilitation of completely edentulous patients with a high degree of bone resorption. In these clinical cases, the soft tissues of the lower third of the face need to be respected, and a fixed-removable solution is the only option to have good hygiene control. Nevertheless,

Abstract:

The partially edentulous in the posterior maxilla bone is produced mainly by the loss of molars due to caries, periodontal disease and excessive force supported by the teeth of this sector. Dental implants greater than 10 mm, are rarely placed in this area due to a higher probability of failure for the low bone volume and bone quality poor. In the skull, in the post jawbone relationship, we find a pterygomaxillary buttress. This allows, in some situations, the rehabilitation of atrophic jaws by placing implants with a parasinusal angulation, avoiding surgical techniques or more complex procedu

Abstract:

Atrophic anterior maxilla edentulous space could pose a significant challenge to successful osseointegrated implant due to inadequate labio-palatal dimensions. The load transferring to surrounding bone is a key factor for the long-term success of implant treatment. Thus, the aim of this study was to evaluate the influence of bone quality change in age-related bone mechanical property (AMP), cortical bone thickness (CBT) and incisal relationship (ICR) on the biomechanical performance of narrow diameter implant placed in atrophic anterior maxilla via finite element method.

Abstract:

AbstractSinus augmentation in conjunction with implant placement is widely considered to be a predictable and successful treatment option for the edentulous posterior maxilla. However, the anatomical changes of the posterior maxilla following tooth extraction (namely alveolar atrophy and pneumatisation of the maxillary sinus) creates unique challenges for implant and prosthodontic rehabilitation. A large volume of literature has been published regarding the surgical indications and treatment planning for implants in the posterior maxilla. In comparison, there is a relative paucity of literatur

Introduction: the bony atrophy of the maxillary ridge is always a limitation to install dental implants. The Ridge Split procedure proves to be a successful technique to perform the management of horizontal defects, increasing the dimensions of the atrophic ridge to immediately install dental implants. Aim: to describe the clinical use of the Ridge Split technique as a treatment for bone augmentation in the horizontal direction of the atrophic maxilla. Case presentation: the case of a female patient of 61 years of age, partially edentulous, who seeks to recover her upper teeth was presented. T

Abstract:

Maxillary sinus floor elevation via a lateral approach is a predictable technique to increase bone volume of the edentulous posterior maxilla and consequently for dental implants placement. The sinus floor is elevated and it can be augmented with either autologous or xenogeneic bone grafts following an opening bone window created on the facial buccal wall. Maxillary septa are walls of cortical bone within the maxillary sinus. The septa shape has been described as an inverted gothic arch arising from the inferior or lateral walls of the sinus and may even divide the sinus into two or more cavit

Abstract:

When the posterior maxilla is atrophic, the reference standard of care would be to perform sinus augmentation with an autologous bone graft through the lateral approach and delayed implant placement. However, placement of short implants with the osteotome sinus floor elevation technique and without graft can be proposed for an efficient treatment of clinical cases with a maxillary residual bone height of 4 to 8 mm. The use of grafting material is recommended only when the residual bone height is ≤4 mm. Indications of the lateral sinus floor elevation are limited to cases with a residual bone h

Abstract This is a case report of the restoration of a partially edentulous atrophic anterior maxilla and atrophic mandibular posterior ridges. This case report demonstrates one method for successful treatment of partial edentulism at No. 7 to 10, where interlock attachments on natural cuspids and mini dental implants support an acrylic-based screwless fixed detachable partial denture to provide lip support and masticatory function in the anterior maxilla. The presenting qualities of this case were similar to combination syndrome.

Dental implants are considered the first choice to replace lost or non-restorable teeth. However, the posterior maxilla remains a challenge in its management because of the quality of bone in the posterior maxilla. Osseo densification (OD) concept has been proposed in the literature to improve primary implant stability, which is an important aspect of osseointegration. Densah bur is novel drills specially designed to enhance a bone density by Osseo densification, which in turn increases primary stability.

This review describes the role of modern preprosthetic surgery. The atrophic edentulous jaw can cause severe functional impairment for patients, leading to inadequate denture retention, reduced quality of life, and significant health problems. The aim of preprosthetic surgery is to restore function and form due to tooth loss arising from congenital deformity, trauma, or ablative surgery. Alveolar bone loss is due to disuse atrophy following tooth loss. The advent of dental implants and their ability to preserve bone heralded the modern version of preprosthetic surgery.
