Flapless Guided Implant Surgeries Compared with Conventional Surgeries Performed by Nonexperienced Individuals: Randomized and Controlled Split-Mouth Clinical Trial.

PURPOSE: The study aimed to evaluate the outcomes of flapless guided surgery related to surgery, patient, operator, assistant, and advisor, comparing it with conventional surgery performed by undergraduate students who had never placed implants in patients. MATERIALS AND METHODS: A randomized controlled split-mouth clinical trial was carried out. Ten patients with bilateral mandibular posterior tooth loss received an implant on each side with conventional flap surgery or flapless guided surgery that was performed by undergraduate students. Surgery time, pain, patient satisfaction, quantity of consumed medications, time of procedure, ease of procedure, anxiety, and stress were assessed. RESULTS: Conventional surgery showed statistically significantly inferior results compared with flapless guided surgery in terms of procedure time (56 minutes, 36 seconds ± 8 minutes, 38 seconds vs 30 minutes, 1 second ± 6 minutes, 2 seconds), consumption of analgesic medications (49 tablets vs 15 tablets), intraoperative (1.75 ± 1.56 vs 0.65 ± 0.64) and postoperative pain (4.62 ± 2.17 vs 1.17 ± 0.72), and operator anxiety (4.76 ± 1.66 vs 3.47 ± 1.50), respectively. CONCLUSION: Flapless guided implant surgeries performed by individuals with no previous clinical experience showed reduced surgery time and delivered better patient-reported outcomes both in the intraoperative and postoperative periods; reduced medication consumption; and showed better results in the operator and assistant perspectives.

Estudo dos acidentes com instrumentos perfurocortantes em clínica de graduação em odontologia / A Study about occurrences during procedures with sharpening instruments into college dentistry clinic

Introdução: A biossegurança exerce papel fundamental na prevenção de acidentes ocupacionais na área da saúde, principalmente com os materiais perfurocortantes. Ma-teriais e Métodos: O objetivo deste trabalho foi realizar levantamento epidemiológico por meio de análise das fichas de notificação de acidentes ocorridos em clínica odontológica, preenchidas pelos alunos e funcionários de uma instituição de ensino superior, em Vitória, ES, durante o período de março de 2014 a março de 2019. Resultados: Foram avaliados um total de 76 fichas de notificação, registrando 69 (90,78%) ocorrências com alunos da graduação e 7 (9,22%) com funcionários. O local de maior incidência foi a clínica com 47 (61,84%) acidentes, 23 (30,27%) no expurgo e 4 (5,26%) na central de esterilização. Conclusão: Após a realização deste estudo pode-se concluir que o índice de acidentes com materiais ou instrumentos perfurocortantes é pequeno quando analisados os números de atendimentos realiza-dos. Protocolos de biossegurança e normas de conduta clínica precisam ser seguidos para minimizar ainda mais os riscos de acidentes.

Introduction: Biosafety, in the health area, plays a funda-mental role in the prevention of occupational accidents, mainly with sharpening instruments. Methodology: The purpose of this study was performing an epidemiological survey by analyzing the notification forms about the acci-dents which occurred into the dentistry clinic, reported by undergraduates and college staff from a higher education institution, in Vitória City-Espírito Santo State, during the period from march 2014 to march 2019. Results: 76 notification forms were totally analyzed, highlighting the number of 69 occurrences with undergraduates which presented percentage level of (90,78%), and 7 occurrences with the college staff which presented the percentage level of (9,22%). The place with the highest incidence of accidents reporting was in the dentistry clinic with the number 47 which presented the percentage level of (61,84%), and the number 23 in the purge area which presented the percentage level of (30,27%), and for last, at the sterilization plant, the number 4 which presented the percentage level of (5,26%). Conclusion: After conducting this study, it's possible to understand that the accidents rate during the use of sharpening instruments and materials is low when compared to the quantity of dental procedures performed. Biosafety protocols and standards of clinical conduct need to be followed to further minimize the risks of accidents.
