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.

Introduction: In recent years, procedures with the use of dental implants have increased worldwide, reaching approximately one million dental implants per year. In recent years, a platelet concentrate called FRP (fibrin-rich plasma) has been the subject of clinical studies. Associated with this, the biomaterial Bio-Oss® (Geistlich), as it is biodegradable, biocompatible, non-toxic, and has low immunogenicity, and bio stimulators can act in the regeneration of bone tissue, as it establishes with the cells the appropriate biological niche (favorable microenvironment) for bone growth. Objective: Therefore, the present study aimed to evaluate, through a brief systematic review, the results that involve bone formation for dental implantation, with the use of biomaterials such as fibrin-rich plasma and Bio-Oss®. Methods: The model used for the review was PRISMA. Was used databases such as Scopus, Scielo, Lilacs, Google Scholar, PubMed. Results: Fibrin-rich plasma (FRP) as an autologous biomaterial for use in oral and maxillofacial surgery presents most leukocytes, platelets, and growth factors, forming a fibrin matrix, with three-dimensional architecture. The Bio-Oss® biomaterial (Geistlich), as it is biodegradable, biocompatible, non-toxic, and has low immunogenicity and bio stimulators can act in the regeneration of bone tissue, since it establishes with the adenomatous mesenchymal stem cells the appropriate biological niche for bone growth and, thus, allowing the dental implant to be as effective as possible. Conclusion: The use of FRP associated with Bio-Oss® seems to illustrate high success rates with minimal costs, which may reduce the amount of bone graft needed to fill the sinus cavity, reducing the costs of the procedure.

OBJECT The authors describe a novel technique using computer-assisted design (CAD) and computed-assisted manufacturing (CAM) for the fabrication of individualized 3D printed surgical templates for frontoorbital advancement surgery. METHODS Two patients underwent frontoorbital advancement surgery for unilateral coronal synostosis. Virtual surgical planning (SurgiCase-CMF, version 5.0, Materialise) was done by virtual mirroring techniques and superposition of an age-matched normative 3D pediatric skull model. Based on these measurements, surgical templates were fabricated using a 3D printer. Bifrontal craniotomy and the osteotomies for the orbital bandeau were performed based on the sterilized 3D templates. The remodeling was then done placing the bone plates within the negative 3D templates and fixing them using absorbable poly-dl-lactic acid plates and screws. RESULTS Both patients exhibited a satisfying head shape postoperatively and at follow-up. No surgery-related complications occurred. The cutting and positioning of the 3D surgical templates proved to be very accurate and easy to use as well as reproducible and efficient. CONCLUSIONS Computer-assisted virtual planning and 3D template fabrication for frontoorbital advancement surgery leads to reconstructions based on standardizedmeasurements, precludes subjective remodeling, and seems to be overall safe and feasible. A larger series of patients with long-term follow-up is needed for further evaluation of this novel technique.

Dental implants are a widely used treatment modality for oral rehabilitation. Implant failures can be a result of many factors, with poor osseointegration being the main culprit. The present systematic review aimed to assess the effect of stem cells on the osseointegration of dental implants. An electronic search of the MEDLINE, LILACS, and EMBASE databases was conducted. We examined quantitative preclinical studies that reported on the effect of mesenchymal stem cells on bone healing after implant insertion. Eighteen studies that fulfilled the inclusion criteria were included. Various surface modification strategies, sites of placement, and cell origins were analyzed. The majority of the selected studies showed a high risk of bias, indicating that caution must be exercised in their interpretation. All the included studies reported that the stem cells used with graft material and scaffolds promoted osseointegration with higher levels of new bone formation. The mesenchymal cells attached to the implant surface facilitated the expression of bio-functionalized biomaterial surfaces, to boost bone formation and osseointegration at the bone–implant interfaces. There was a promotion of osteogenic differentiation of human mesenchymal cells and osseointegration of biomaterial implants, both in vitro and in vivo. These results highlight the significance of biomodified implant surfaces that can enhance osseointegration. These innovations can improve the stability and success rate of the implants used for oral rehabilitation.

Introdução: A osteonecrose induzida por medicamentos (ONIM) é uma grave complicação da terapia com drogas antirreabsortivas, como os bifosfonatos (BFs). Embora ocorra com mais frequência em pacientes oncológicos, os quais utilizam BFs endovenosos, pacientes usuários de BFs orais para tratamento de osteoporose também se encontram no grupo de risco, principalmente quando procedimentos odontológicos cirúrgicos como exodontias e implantes dentários são realizados. Objetivo: Relatar três casos de pacientes que fizeram usode BFs no passado ou ainda utilizavam a medicação durante cirurgia para instalação de implantes dentários, abordando os principais fatores de risco para o desenvolvimento da ONIM. Conclusão: O conhecimento prévio pelo implantodontista dos efeitos adversos da terapia com drogas antirreabsortivas em pacientes que necessitam de reabilitação dentária é de extrema importância no manejo desses pacientes, uma vez que elas podem prejudicar a longevidade das reabilitações com implantes e induzir à osteonecrose dos maxilares,comprometendo não somente a saúde bucal como também interferindo negativamente na qualidade de vida dos pacientes.Introduction: Bisphosphonate-related osteonecrosis of the jaw (BRONJ) is a serious complication of therapies with anti-resorptive drugs, such as bisphosphonates (BFs). Although it occurs more often in oncology patients who use intravenous BFs, patients who use oral BFs for osteoporosis are also in the risk group, especially when surgical dental procedures such as dental extraction or dental implants are performed. Objective: To report three cases of patients who were submitted to BF therapy in the past or were still using the medication during dental implants surgery and developed BRONJ and lost the implants. Conclusion: It is extremely important that the dentists are aware of the adverse effects of BF therapy in patients that require dental rehabilitation for the management thereof, since they can reduce the longevity of dental implants and induce osteonecrosis of the jaw, compromising not only their oral health but also these patients’ quality of life.

Próteses sobre implante representam um grande avanço para a odontologia, porém, complicações mecânicas como afrouxamento ou fratura do parafuso protético, têm sido relatadas. O presente trabalho objetiva revisar a literatura a respeito dessas complicações. O afrouxamento de um parafuso implica em sobrecarga aos demais parafusos que poderão também afrouxar e pode favorecer a ocorrência de falhas, uma delas é a fratura de parafusos e componentes. Quando ocorre a fratura o profissional deverá ter muito cuidado durante a remoção para não danificar a superfície do implante e/ou componente. A prevenção dessas complicações começa com o planejamento do tratamento e um ajuste oclusal adequado. Outro ponto importante são as consultas protéticas de manutenção e avaliação dos parafusos, com possível substituição preventiva.Descritores: Prótese Dentária Fixada por Implante; Implantes Dentários; Revisão.ReferênciasMoraschini V, Poubel LA, Ferreira VF, Barboza Edos S.

Purpose: To present an experimental strategy for successfully capturing the margins of prepared single teeth with an intraoral scanner (IOS). Methods: The protocol was as follows: (1) an intraoral impression was captured with an IOS, without taking care of the visibility of the margins; (2) a partial analog impression was taken by means of a 3D-printed custom tray filled with polyvinylsiloxane light, after the removal of a retraction cord; (3) the hollow portion of the analog impression, with the preparation margins clearly visible, was scanned extraorally with the same IOS; (4) the scan of the analog impression was imported into computer-assisted-design (CAD) software, where its normals were inverted; (5) the scan with inverted normals was registered on the first intraoral scan, and replaced it; (6) the technician designed the final restoration, which was fabricated and delivered for application. The study outcomes were: (1) the marginal adaptation of the final crown; (2) the quality of interproximal contacts; and (3) the quality of occlusal contacts. Results: Thirty patients (18 males, 12 females; mean age 51.3 ± 11.6 years) were selected for this study. All these patients were restored with a monolithic translucent zirconia crown, fabricated following the aforementioned protocol. The clinical precision and the marginal adaptation of the crowns were optimal, interproximal contact points were perfect, and the only necessary adaptations were occlusal, with some minor precontacts that had to be polished. Conclusions: The present protocol seems to be compatible with the fabrication of clinically precise zirconia crowns. Further studies are needed to confirm these results.
