ABSTRACT
Introdução: Intermediários protéticos de diferentes formas, materiais ou métodos de confecção utilizados em tratamento com coroas sobre implante podem gerar impacto sobre o resultado final da reabilitação. Objetivo: Avaliar a interferência de dois intermediáros protéticos: (1) pré-fabricados em titânio (GT) ou (2) personalizados em zircônia (GZ) sobre a satisfação e qualidade de vida dos pacientes reabilitados por meio de coroas livres de metal sobre implantes unitários instalados na região do sorriso. Material e métodos: Um ensaio clínico não randomizado-controlado e cego foi realizado. Todos os pacientes passaram por uma etapa de coroa provisória antes da instalação da coroa final. A satisfação foi avaliada por meio da escala visual analógica EVA e a qualidade de vida por meio do Oral Impacts on Daily Performances (OIDP) e do Oral Health Impact Profile (OHIP-14). As avaliações aconteceram em três tempos, baseline (T0), sete dias após a instalação da coroa provisória (T1) e sete dias após a instalação da coroa final (T2). Os dados foram avaliados por meio do teste de Mann-Whitney, para as análises intergrupos, e do teste de Wilcoxon para as avaliações intragrupos. O teste de correlação de Spearman foi realizada para avaliação dos fatores que interferiram na estética final. Resultados: Vinte e quatro pacientes foram incluídos, a média de idade foi de 41,88 anos. Foram instalados 26 implantes, 14 no GT e 12 no GZ, a região anterior teve 20 implantes instalados e a região posterior teve 06 implantes. Houve uma melhora significativa da satisfação, independentemente do grupo, entre T0 e T1 (p=0,013) e entre T1 e T2 (p<0,001). Considerando a amostra como um todo, as dimensões do OHIP-14 foram influenciadas positivamente entre T0 e T1 (p<0,001) e T0 e T2 (p<0,001). E as performances do OIDP também melhoraram entre T0 e T1 (p=0,007), T1 e T2 (p=0,007) e T0 e T2 (p<0,001). Conclusão: Os diferentes intermediários protéticos testados nesta pesquisa parecem não interferir nas variáveis estudadas e a instalação de coroa livre de metal sobre implante parece desempenhar um papel importante na melhoria dos níveis de satisfação e qualidade de vida dos pacientes (AU).
Introduction: Prosthetic abutment of different shapes, materials or fabrication methods used in oral rehabilitation can play a role in the success of the rehabilitation. Objective: To evaluate the influence of two different abtments: (1) prefabricated titanium (GT) or (2) customized zirconia (GZ) in the quality of life, and patients' satisfaction wearing metal-free crowns on single implants placed in the smile region. Material and methods: A non-randomized-controlled-blinded clinical trial was performed. All patients received a temporary restoration before the final metal-free crown. The patient's satisfaction was assessed by a Visual Analog Scale (VAS), and quality of life by the Oral Impacts on Daily Performances (OIDP) and the Oral Health Impact Profile (OHIP-14). The follow-up was performed at baseline (T0), seven days after provisional crown placement (T1) and seven days after the final crown (T2). Data were assessed using the MannWhitney test for intergroup analyses, and the Wilcoxon test for intragroup assessments. The Spearman correlation test was performed to evaluate the factors that can influence the final esthetics. Results: Twenty-four patients were included; the mean age was 41.88 years. Twenty-six implants were placed, fourteen in GT and twelve in GZ. Twenty implants were placed in the anterior region and 06 in the posterior. A significant improvement was noticed in the patient's satisfaction, regardless of the group, between T0 and T1 (p=0.013) and T1 and T2 (p<0.001). Considering the whole sample, the dimensions of the OHIP14 were positively influenced between T0 and T1 (p<0.001) and T0 and T2 (p<0.001). The performances of the OIDP also improved between T0 and T1 (p=0.007) as well as between T1 and T2 (p=0.007) and between T0 and T2 (p<0.001). Conclusion: The prosthetic abutments tested in this study do not seem to play a role in the variables studied and the metal-free crown placement seems to play an important role in improving the levels of patient's satisfaction and quality of life (AU).

In a single implant restoration of maxillary anterior teeth, it is difficult to accomplish an aesthetic restoration of the implant prosthesis in the case of gingival recession and bone defect problems. To maintain aesthetic stability in the long term, it is important to place the implant in the ideal position as well as the recovery of the soft tissue and harmony with the prosthesis. Not only ideal implant position but also the harmony with surrounding soft tissues are important to fabricate aesthetic implant prosthesis for these cases. for these cases, a 47- years -old male with lowered level of osseous crest and gingival recession on maxillary anterior tooth was treated with guided bone regeneration and gingival recontouring.
