Dental Rehabilitation

The goal of mandibular reconstruction is to rehabilitate the patient by restoring occlusal relationships, lower facial contour, oral continence, and a denture-bearing surface. One of the major advantages of the use of vascularized bone over all other methods of mandibular reconstruction is its ability to achieve dental rehabilitation rapidly. The use of osseointegrated dental implants is a valuable adjunct in oral rehabilitation. It provides the most rigid form of stabilization to withstand the forces of mastication. In situations In which soft tissue reconstruction or the height of the alveolar ridge is not sufficient for a tissue-borne denture, implants offer the most suitable alternative. Mandibular reconstruction with free tissue transfer techniques is Ideally suited for the placement of implants. These can be inserted at the time of mandibular reconstruction. Four months after surgery, when the integration process has occurred, the implants are unroofed, loaded, and ready for prosthetic placement. We will present several representative patients who underwent mandibular reconstruction with microvascular free bone transfer who have been successfully rehabilitated by osseointegrated implants. The process of osseointegration, different types of dental implants, and issues regarding radiation and Implants are discussed. This is the first report of dental rehabilitation by primary placement of dental implants in patients undergoing microvascular mandibular reconstruction.

Introduction: The treatment of atrophic jaw fractures requires extensive knowledge by the maxillofacial surgeon. The correct diagnosis and planning optimize the possibility of oral rehabilitation towards many possible alternatives. The difficulty in repairing these fractures makes the treatment complex, in which normally invasive techniques are used. However; which give us satisfactory and predictable aesthetic-functional results. Objective: The objective of this work is to report an atrophic jaw fracture and posterior dental implants rehabilitation. Case report: A 53 years old female patient, victim of in face aggression referred to the emergency care. At the clinical examination, the patient had laceration in the upper lip region and the left side of the mandibular area, with bilateral mobility and paresis. In the oral examination, total lower and partial upper edentulism. After tomographic evaluation, a bilateral fracture of the mandibular body was confirmed, with significant bone fragments uneven. Surgery was performed with total transcervical access and use of reconstruction plate. After 90 days of follow-up, the oral rehabilitation with osseointegrated implants was performed. Conclusion: Complex atrophic mandible fractures in total edentulous patients can be treated with open reduction and stable fixation, allowing a faster return to normal function, improve of quality of life and assists in increasing safety for implant installation.KeywordsEdentulous jaw; Jaw fixation techniques; Dental implants.

The Ideal

The implant-supported rehabilitation of atrophic mandibles (AM) with severe bone resorption is challenging for both surgical and prosthetic procedures due to the high risk of mandible fracture during implant surgery and postoperatively due to the masticatory load. The aim of case presentations was to demonstrate treatment alternatives for patients with AM who required oral rehabilitation with osseointegrated implants (OIs) according to the residual mandibular bone volume. When bone is 9 mm in height, the ideal treatment is the use of narrow, short OIs. When the bone height is 5 to < 9 mm, mandibular reinforcement with reconstruction plates using the intraoral approach and simultaneous placement of osseointegrated implants are proposed. In cases where bone height is < 5 mm, the choice of treatment is mandibular reconstructive surgery with an autogenous bone graft and biomaterials. The fundamental principles of this protocol are to reduce the morbidity and complications associated with the surgical procedure, which would reduce both the time and cost of full dental rehabilitation. The choice of the technique for mandibular reconstruction should be indicated according to the magnitude of the atrophy.

Introduction: Dental implant procedures have increased worldwide, reaching approximately one million dental implants per year. The optimization of faster and more accurate techniques by dentists and postoperative surgeons with better results and quality of life stimulated the development of numerous software and hardware for performing computer-guided surgeries, so-called virtual surgeries (VS). Objective: to present, through a systematic review, the main considerations of virtual surgery in dentistry and their respective advantages, disadvantages, and limitations. Methods: The model used for the review was PRISMA. We used databases such as Scielo, Lilacs, Google Scholar, PubMed. Major findings: In the scenario of VS in dentistry, advances in technology have contributed to the improvement of the models, since there was only the direct molding technique to obtain patient models, with the positioning of implants not very favorable in terms aesthetics. The information that is acquired in the 3D reconstructions allows us to determine the quantity and quality of the available bone and also allows the simulation of the installation of the implants in a virtual environment. This provides predictability of techniques and difficulties that can be encountered during surgical intervention, reducing the time and the possibility of errors, allowing the overall reduction of oral rehabilitation costs. Conclusion: Preoperative virtual planning and reconstruction of the mandible guided by dental implants through preoperative designs provide high success rates for the implant and dental rehabilitation, benefiting also prosthetic restorations supported by fixed implants. Still, the concept of using personalized implants with the help of 3D virtual treatment planning, stereolithographic models, and computer-assisted design greatly improves the mandibular restoration and helps to obtain a good facial profile, aesthetic and dental rehabilitation, avoiding complications with the grafts autologous.

ABSTRACTEctodermal dysplasia is a rare group of inherited disorders characterized by aplasia or dysplasia of tissues of ectodermal origin, such as hair, nails, teeth and skin. Dental manifestations include hypodontia, complete anodontia or malformed teeth. Oral rehabilitation is the major surgical challenge in such patients. It frequently requires alveolar reconstruction followed by dental implants. We report a case of hypohidrotic ectodermal dysplasia, which was managed with reconstruction of both the upper and the lower alveolus using free fibula flaps with dental rehabilitation using osseointegrated implants.

Osseointegrated implants have been an optimal treatment option for dental rehabilitation of fully or partially edentulous patients. Although peri-implantitis remains as the most common local risk factor for dental implant failure, the development of oral cancer involving the soft tissue around the titanium may lead to early implants loss and impact the quality of life of the patient negatively. Oral squamous cell carcinoma (OSCC) is the most common malignancy among head and neck tumors. It has higher prevalence in men over 50 years old, and in tobacco and/or alcohol users. Unfortunately, oral cancer is often detected in advanced stages, when the treatment options are limited. Thus, OSCC typically has poor prognosis. Despite the recent advances in oral carcinogenesis understanding, the relationship between dental implants and the development of malignant lesions around them is not completely understood. It has been suggested that the titanium corrosion occurring at the top of dental implants causes the release of metal ions. These ions might lead to oral epithelial genetic damage and higher susceptibility of normal mucosa to malignant transformation. The aim of this chapter was to review the clinical characteristics, diagnosis, and the possible carcinogenic mechanisms involved in oral cancer around dental implants.

In the following case report, three osseointegrated implants placed in a dysfunctional and nonaesthetic position were successfully relocated with innovative surgical techniques were followed by a comprehensive dental rehabilitation. The goal of this report is to communicate the surgical techniques used to successfully relocate dental implants rather than replace them. Two techniques were used for these implants relocation. One technique consisted of displacing the integrated implant with some similarity to the alveolar distraction osteogenesis but without using the distraction device. The second surgical technique involved the displacement of the 2 adjacent implants, similarly to the first approach, except that an osseoinductive molecule, recombinant human bone morphogenetic protein-2, was used for guided bone growth. It was possible to relocate dental implants within bone blocs and rehabilitate them to adopt new dental abilities by complying with bone regeneration parameters. However, advanced treatment planning with computerized tomography scans, parametric software, and stereolithography models as well as guided surgery and bone regeneration products were used.
