ABSTRACT
AIM: The aim of this study was to analyze and follow-up implants placed in the posterior maxillary regions previously grafted with homologous bone. MATERIALS AND METHODS: Forty-one grafts with homologous bone blocks were performed in maxillary sinuses, and 121 implants were placed in premolar and molar regions approximately 6 months after the grafts. Patients were followed up for periods varying from 12 to 124 months after rehabilitation. RESULTS: The results showed two implant failures, for a 98.3% success rate during the follow-up period. DISCUSSION: The implants placed had an average torque of 40 N-cm, regardless of the, design, diameter, and length of the implants used. CONCLUSION: After following up on the implants placed in this study, we concluded that those placed in regions of the maxillary sinuses previously grafted with homologous bone blocks had high long-term success rates and met the functional masticatory requirements.
ABSTRACT
A substituição de um elemento dental por um implante em pacientes que apresentam tecido gengival delgado gera uma preocupação devido à translucidez gengival, onde a coloração acinzentada do titânio pode levar ao fracasso estético do tratamento. Desta maneira, os implantes de zircônia se diferenciam principalmente por sua coloração clara, a qual se aproxima das características de cor da raiz, e por sua biocompatibilidade, além de possibilitarem a escolha do paciente por um tratamento totalmente livre de metal. Portanto, este relato de caso clínico demonstrou uma inovação técnica por meio da utilização de um implante confeccionado em zircônia para solução de um caso clínico de alta complexibilidade estética em uma paciente jovem, com fenótipo gengival delgado e alto grau de exigência estética. O caso foi finalizado com prótese cimentada e facetas metal free confeccionadas por meio de cerâmica injetada. Após a finalização do caso, concluiu-se que, apesar da desvantagem relacionada à sensibilidade técnica, o implante confeccionado em zircônia possibilitou a solução estética deste caso clínico de fenótipo gengival delgado, sem a necessidade de utilização de enxertos gengivais.
The replacement of a dental element in patients with thin gingival tissue generates a concern due to gingival translucency, where the titanium gray coloration can lead to failure of the treatment. Thus, the zirconia implants are distinguished primarily by their coloration and their biocompatibility, in addition to enabling the selection of a totally metal-free treatment. Therefore, this clinical report, showed an innovative technique using a zirconia implant in a clinical situation with high complex esthetic needs for in a young patient with thin gingival phenotype and high level of aesthetic requirement. The clinical case was concluded with cemented prosthesis and metal-free veneers made by pressed ceramics. After the end of the case, it was concluded that, despite the disadvantage related to the technical sensitivity, the zirconia implant provided an aesthetic solution of this clinical case of thin gingival phenotype, without the need of gingival grafts.
