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.

Rare Group

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.

ABSTRACT Aim Realize the surgery of sinus lifting floor to allow the installation of osseointegrated implants for oral rehabilitation, with the combination of different biomaterials, autogenous bone and lyophilized bovine bone. Background Oral rehabilitation using the installation of osseointegrated implants is an alternative surgical approach that results in the satisfactory form, function and esthetics of the dental units. Case report After clinical, dental and laboratory assessment, a 47-year-old female patient underwent full maxillary oral rehabilitation involving the installation of osseointegrated implants to allow her to meet the physiological demands of occlusion and mastication. It was found that the patient had fully pneumatized maxillary sinuses with insufficient height to anchor implants, with a loss of the vertical dimension of the occlusal and masticatory functions due to general dental loss, compounded by the use of ill-fitting dentures; hence, the choice was made to take autogenous bone from the patient's chin area and supplement it with lyophilized bovine bone as collateral for larger areas to be grafted. It was also decided to avulse the remaining tooth units due to their impairment by periodontal disease. Conclusion Bone grafts do not constitute suitable alternatives in the cosmetic and functional rehabilitation of the maxilla in patients requiring bilateral sinus elevation. The chin region provides bone tissue that, when complemented by lyophilized bovine bone grafts, ensures greater volume and less invasive surgery. In the case described here, a height gain of approximately 550% was obtained, making it possible to anchor seven implants. Clinical significance In this study, the surgical procedures used for grafting a combination of autogenous and lyophilized bovine bone, aimed to elevate the maxillary sinus floor to allow the installation of osseointegrated implants for oral rehabilitation.

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.

Background: Ameloblastoma is the second most common odontogenic tumor. It shows a locally aggressive behavior, with a high level of recurrence. Wide resection of the jaw is recommended for treatment of ameloblastoma. However, radical surgery causes an abnormal mandibular movement, facial asymmetry, and masticatory dysfunction. Methods: Three cases of different types of ameloblastoma is presented, with different reconstruction techniques including Non-Vascularized Bone Graft (NVBG), Osteocutaneous Fibula Free Flap (OFFF), and Deep Circumflex Iliac Artery flap (DCIA). Results: In all three cases the tumor site was successfully reconstructed to obtain very good esthetic results as well as functional oral rehabilitation with implants and fixed prosthetics for optimal masticatory function. Conclusion: For reconstruction of the mandible, we prefer bone grafts from the iliac crest. The natural curvature and variable bone height offer a very good reconstruction of the defect.

Jaw Fractures

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.

Autogenous Bone Grafts

The successful use of osseointegrated implants in the treatment of partial or complete edentulism requires a sufficient bone support. Whenever rehabilitation in atrophic edentulous areas is needed, bone augmentation procedures are recommended. The aim is to provide adequate amount of supporting bone to achieve a prosthetically guided implant placement. This in turn leads to functional and aesthetic improvements that can be maintained on the long term. Bone grafting of the atrophic site can be performed either prior to implant placement or at the time of implantation. Irrespective of the timing, bone augmentation by means of autogenous bone grafts is a reliable technique, as confirmed by several studies. On the other hand, long-term evidence on the use of autogenous chin block grafts in preprosthetic implant surgery is still scarce. Thus, the purpose of the present case is to report the 20-year clinical and radiological outcome of autogenous chin block grafts used to augment a bilateral defect due to agenesis of the upper lateral incisors for implant placement purposes.

Marginal Mandibulectomy

Mandibular reconstruction techniques are always a challenge to oral and maxillofacial (OMF) surgeons. Techniques and treatment plans that offer the patient OMF rehabilitation should always be available. Technological innovations have enabled more rapid, safer, and secure treatment than in the past. This article describes a case using a different approach. The patient was treated with marginal mandibulectomy and immediate rehabilitation with osseointegrated implants; a hybrid prosthesis was fabricated a short time thereafter. This treatment plan demonstrated its utility and efficiency in this case. An approach with fewer surgeries and OMF rehabilitation needs be considered in all cases.
