Abstract(s)
Os avanços tecnológicos, como a tomografia computadorizada de feixe cónico e a criação de softwares que possibilitam a realização de planeamento virtual, proporcionaram o surgimento da cirurgia guiada por computador. Este trabalho teve como objetivo investigar as vantagens e as limitações da utilização de cirurgia guiada por computador (estática) sem retalho na implantologia. Trata-se de uma revisão da literatura dos últimos quinze anos, onde foram incluídas apenas pesquisas realizadas em humanos. Verificnesta revisão, que as principais vantagens atribuídas a este tipo de cirurgia são: maior precisão no posicionamento do implante, menor risco de causar danos às estruturas anatómicas, menor perda óssea de osso marginal, redução de sinais inflamatórios no pós-operatório, mitigação do risco de bacteriemia e satisfação do paciente. Concluímos ainda, que as principais limitações atribuídas à cirurgia guiada por computador sem retalho foram: dificuldade de irrigação durante a cirurgia; impossibilidade de realizar simultaneamente técnicas de aumento ósseo; redução do tecido queratinizado ao redor do implante associada à técnica sem retalho, custo da técnica e necessidade de experiência profissional para uma adequada execução deste tipo de cirurgia. Concluímos, que a cirurgia guiada por computador sem retalho é muito benéfica para o paciente, quando são respeitadas as limitações deste tipo de procedimento.
Technological advances, such as the creation of cone beam computed tomography and softwares that made it possible to carry out virtual planning, have enabled computer-guided surgery. This study aimed to investigate the advantages and limitations of using computer-guided (static) flapless surgery in implantology. In this review, we found that the main advantages attributed to this type of surgery are: greater precision in the positioning of the implant, less risk of causing damage to anatomical structures, less bone loss of marginal bone, reduction of inflammatory signs in the postoperative, mitigation of the risk of bacteremia and patient satisfaction. We also found that the main limitations attributed to computer-guided flapless surgery were: difficulty in irrigation during surgery; inability to simultaneously perform bone augmentation techniques; reduction of keratinized tissue around the implant associated with flapless technique, cost of the technique and need for professional experience for proper execution of this type of surgery. We conclude that the flapless computer-guided surgery is quite advantageous for the patient, when the limitations of this type of procedure are respected.
