Longevity of dental implants in type IV bone: a systematic review

Bone quality and quantity are important factors with regard to the survival rate of dental implants. The aim of this study was to conduct a systematic review of dental implants inserted in low-density bone and to determine the survival rate of dental implants with surface treatments over time. A systematic review of the literature was undertaken by two independent individuals; the Medline/PubMed database was searched for the period July 1975 to March 2013. Relevant reports on bone quality and osseointegration of dental implants were selected. The search retrieved 1018 references, and after inclusion and exclusion criteria were applied, 19 studies were selected for review. A total of 3937 patients, who had received a total of 12,465 dental implants, were analyzed. The survival rates of dental implants according to the bone density were: type I, 97.6%; type II, 96.2%; type III, 96.5%; and type IV, 88.8%. The survival rate of treated surface implants inserted in low-density bone was higher (97.1%) than that of machined surface implants (91.6%). Surface-treated dental implants inserted in low-density bone have a high survival rate and may be indicated for oral rehabilitation. However, more randomized studies are required to better evaluate this issue.

Considerações clínicas em implantes imediatos

The biological principles of osseointegration caused the rehabilitation treatment with osseointegrated implant become a safe, well alternative accepted by the dental community for the high success rate, allowing the preparation of functional and aesthetic prostheses in edentulous and partial patients. We passed the initial phase of functional vision for an aesthetic approach, too, depending on the demands of the patient and the quest for excellence by professionals. Over these last years, implant treatment has undergone many changes in surgical and prosthetic protocols. The less invasive surgical techniques and the development of restorative materials, especially ceramics allow the prosthetic rehabilitation of high functional quality and aesthetics. The installation of implants in sockets immediately after extraction of teeth involved by fracture, periodontal disease, endodontic lesions, is part of the arsenal of techniques for rehabilitating a number of advantages that we get to the outcome of multidisciplinary treatment. For this, we must consider several criteria in its planning as a fundamental unit, adjacent teeth, multiple losses, system, form and number of implants, type of retention of the prosthesis components, the patient expectation of the outcome perspective, gingival biotype, standard of ridge resorption, the smile line, etc. occlusal analysis. With the three-dimensional placement of the implant can immediately join the biological processes of repair of the socket, implant osseointegration, speeding treatment time. Much has been made by companies in the surface treatment of endosseous implants to be osseointegration shortened and restorative procedures started earlier, bringing benefits to the patient and professional. Among the main advantages we can emphasize the preservation of the structures adjacent to the teeth replaced, minor resorption of bone tissue involved...

Tratamento ortodôntico da agenesia de incisivo lateral superior com envolvimento de fratura radicular de incisivo central superior

Patients with agenesis of maxillary lateral incisor must have in your planning functional and aesthetic considerations, important to the success of the treatment, regardless of whether the choice of treatment is closing or opening and maintenance of space for rehabilitation with prosthesis. This choice will depend on factors such as skeletal and tooth structure and profile. Children and adolescents are the group of individuals most exposed to trauma and fracture of the maxillary lateral incisor due to the activities they perform. Proper diagnosis and good treatment are essential to the success of the treatment. This article aims to report a case of agenesis of the maxillary lateral incisor along with the involvement of a root fracture of the maxillary central incisor. The orthodontic treatment was successfully finished with a favorable prognosis for the fractured incisor to stay in a esthetic and functional position.

Aesthetic rehabilitation of oligodontia in primary dentition with adhesive partial denture

The primary teeth are essential for bone development and establishment of the arches on occlusion. Thus, the congenitally absence of teeth may trigger a shift in the balance of the occlusion, promoting disharmony in the structures of the maxilla-mandibular system. However, some interventions are possible to be performed in these cases even in pediatric patients, to redirect growth, preventing growth deviations and reestablishing the aesthetic. The aim of this paper is to report the treatment of a 4-year-old child presenting congenitally absence of mandibular central and lateral incisors and maxilla lateral incisors, which consequently compromises aesthetics, occlusal function, and the development and the functional growth of the bones. The oral rehabilitation was performed with an adhesive partial denture, which was able to restore the aesthetic and the occlusal function, therefore being a viable alternative in the treatment of this patient of little age.

Frequência de ressonância e sondagem peri-implantar em implantes curtos sob carga imediata com prótese total fixa em cantiléver na arcada mandibular: acompanhamento de um ano

This paper presents a case report with the use of short dental implants and immediate prosthesis placement. After 13 months of follow-up, peri-implant probing values are near 1.87 mm and ISQ values around 78.56.

Protocolo mandibular com implantes curtos

Jaws atrophy represents a great challenge to Implantology regarding rehabilitation of edentulous areas. This paper reports an extreme mandibular atrophy with only 9mm of height between the mental foramina. In these situations, treatment options include bone augmentation techniques, transmandibular, or short dental implants. It is well accepted that bone grafts to improve height do not have good predictability. Besides, osteogenic distraction is associated with a great patient discomfort and transmandibular implants are related with high failure rates. Also, surgical-prosthetic rehabilitations with short dental implants had been associated to good success rates. The purpose of this clinical case is to report a severe mandibular atrophy, successfully treated with four short dental implants between mental foramina for implant-supported prosthesis.

Rehabilitacion oral sobre implantes instalados por medio de la tecnica sin colgajo (flapless) y carga inmediata

The oral rehabilitation with osseointegrated implants is a well-documented treatment with high rate of success. Nevertheless, demands related to treatment time and surgical technique began to appear. In this context, the procedure of immediate loading in which the dental prosthesis is placed right after implant surgery has become a constant practice. Although immediate loading has been an important advance, minimally invasive procedures, such as implant placement without raising a mucoperiosteal flap (flapless) are increasingly being performed. Association of immediate loading with the flapless technique improves acceptance by patients and professionals, because no suturing is required. Moreover, it reduces swelling, bleeding during and after surgery, postoperative pain, surgery time, discomfort and hematoma, as well as the need for postoperative medication. These characteristics ease the stages of rehabilitation soon after implant placement, cooperating with prosthodontist's work. Thus, the proposal of this study is to present a clinical case of oral rehabilitation with osseointegrated implants and fixed prosthesis in both arches, in which the flapless technique was applied, followed by immediate loading. It will discuss the diagnosis, prosthetic planning, surgical/prosthodontic procedures and follow-up for 20 months.

Reabilitação oral de paciente com síndrome da combinação: relato de caso

The Combination Syndrome represents an important pathologic condition of the masticatory system that requires a complex rehabilitation treatment. The presence of flaccid mucosa is one of the most common features due to bone resorption of the pre-maxilla caused by anterior hyperfunction of the mandibular teeth on the maxillary complete denture, where the impact of oclusal loading in this region results in movement of the maxillary prosthesis into the ridge, resulting in increased resorption of the residual ridge, internal misfit and loss of the retention of the maxillary complete denture. The presence of flaccid mucosa, in such cases, leads to problems of support and stability of the maxillary complete denture, which can be treated by surgical reduction of the thickness of the tissue or using specific techniques of fabrication of prostheses. This article describes the oral rehabilitation of a patient with the Combination Syndrome where the surgical reduction of flaccid mucosa was not performed, using a modified technique of functional impression in two steps, with the objective of generating forces and less distortion in flaccid mucosa during functional impression.

Resina composta indireta como alternativa funcional e estética em reabilitações protéticas

Due to mechanical and aesthetic improvement properties, continuous fiber-reinforced composites have been developed to replace the metal framework in fixed partial dentures becoming an interesting alternative to conventional treatments. A male patient, 57 years old, attended at Fixed Partial Denture Clinic of Araraquara Dental School - UNESP, complaining about upper right first molar absence. After clinical examination, it was observed: upper right second molar with amalgam restoration and periodontal bone reduction and upper right second premolar unsatisfactory treated. Following the clinical conditions and the patient expectations, it was decided to use a fiber-reinforced composite resin to make a three-element fixed bridge. The patient showed full satisfaction with the aesthetic and functional results. The case has been followed up for 60 months.

Importância do tratamento estético periodontal na reabilitação protética

Gingival recession is a common deformity that affects a large number of people. This condition is frequently associated with esthetic complains and may lead to dental hypersensitivity. Thus, various surgical procedures have been proposed to provide root coverage. Since the 1950s, free and pedicle gingival grafts have been greatly used for treating gingival recession. However, after the 1985 Miller gingival recession classification, and with the development of other appropriated techniques that use subepithelial connective tissue grafts, gingival recession treatments have resulted in more predictable outcomes, especially with respect to Class I and II sites, i.e., in the absence of interproximal bone loss. This article reported the importance of aesthetical periodontal treatment in the prosthetic rehabilitation of a patient with a class I gingival recession with 3 mm of vertical extension in the superior canine. The treatment plan consisted of root coverage using subepithelial connective tissue graft (SCTG) associated with construction of new prosthesis.

Prótese metalocerâmica associada à prótese metaloplástica implantossuportada em paciente desdentado total

The use of different methods and materials should be considered during the planning of implant-supported prostheses. Complications such as fractures of the acrylic resin base, wear and fracture of teeth can occur frequently, creating the need for careful planning for each patient, which can make the selection of the type of treatment more complex. Thus, this article describes the oral rehabilitation of a completely edentulous patient with bimaxillary fixed implant-supported prosthesis, with complaints on aesthetics, loss of vertical dimension and fracture of acrylic resin teeth of the upper arch. After the restoration of vertical dimension, his dentures were replaced with new bimaxillary implant-supported fixed prostheses, ceramic and acrylic resin were used as veneering material for maxilla and mandible, respectively. At the end of the treatment, the patient received bimaxillary flat occlusal splints to protect the teeth and implants of possible parafunctional habits. The approach for the treatment allowed a quick and effective resolution, with aesthetic and functional outcomes very favorable for the patient.
