Introdução:
A estabilidade dos implantes é essencial na osteointegração; A primária depende da
estabilidade mecânica e a secundária é biológica. O momento de carga funcional
depende da estabilidade do implante. O Quociente de Estabilidade do Implante
permite acompanhar a evolução da osteointegração.
Objetivos
Principais: avaliar a evolução do ISQ após colocação tardia de implantes dentários;
comparar sucesso, insucesso do implante e o uso de carga com base nas leituras do
ISQ.
Secundários: avaliar a relação do torque com o ISQ inicial e outras variáveis com o
sucesso do implante e com o valor de ISQ.
Materiais e Métodos
Estudo clínico retrospetivo com recurso a amostra de conveniência composta por
pacientes tratados com implantes dentários (Anyridge®, MegaGen Implant, Daegu,
Coreia do Sul) tardios no período de Outubro 2022 a Abril 2023. ISQ1 medido no dia
da colocação do implante com recurso a SmartPeg 67® e ISQ2 após 3 meses.
Variáveis registadas foram: dados demográficos, torque de inserção, realização de
carga/tipo de carga entre outras.
Resultados
A média de idade dos participantes foi de 52,68±11,94 anos. Os molares inferiores
(n=10; 35,7%) seguidos dos pré-molares superiores (n=8; 28,6%) foram a
localização mais frequente, de forma correspondente os tipos de osso III e IV (n=12;
42,9%) os mais frequentes. Na maioria dos implantes (n=26; 92,9%) não foram
utilizados substitutos ósseos nem membrana (n=17; 94,4%). Na maioria não foi
realizada carga imediata (82,1%). O torque de inserção situou-se maioritariamente
entre 35 e 45 N/cm2 (78,5%). Os valores médios de ISQ 1 e 2 foram respetivamente
73,67±4,57 e 77,1±3,34, não existindo diferença estatisticamente significativa.
Conclusões
Os resultados sugerem que existe uma correlação positiva entre ISQ1 e 2, sem
diferença estatisticamente significativa;
Não foram detetadas diferenças estatisticamente significativas para qualquer uma
das variáveis registadas sobre ISQ 1 e 2, incluindo tipo/realização de carga e torque
de inserção.
Implant stability is essential in osseointegration; Primary depends on the mechanical stability and the secondary is biological. The functional loading moment depends on implant stability. The Implant Stability Quotient allows to keep track on the evolution of osseointegration. Objectives Main: To evaluate the evolution of the ISQ after delayed dental implant placement; to compare success, implant failure and loading based on ISQ readings. Specific: To evaluate the relationship of torque with ISQ1 and other variables with implant success and ISQ values. Materials and Methods A retrospective clinical study using a convenience sample consisting of patients treated with dental implants (Anyridge®, MegaGen Implant, Daegu, South Korea) in the period between October 2022 and April 2023. ISQ1 measured on the day of implant placement using SmartPeg 67® and ISQ2 after 3 months. Variables recorded were demographics, insertion torque, loading/type of loading among others. Results The mean age of the participants was 52.68±11.94 years. The mandibular molars (n=10; 35.7%) followed by maxillary premolars (n=8; 28.6%) were the most frequent location, correspondingly bone types III and IV (n=12;42.9%) were the most frequent. In most cases (n=26; 92.9%) neither bone substitutes or membranes were used (n=17, 94.4%). In the majority, immediate loading was not performed (82.1%). The insertion torque was mostly between 35 and 45 N/cm2 (78.5%). Mean ISQ 1 and 2 values were respectively 73.67±4.57 and 77.1±3.34, with no statistically significant difference. Conclusions The results suggest that there is a positive correlation between ISQ1 and 2, with no statistically significant difference; No statistically significant differences were detected for any of the variables recorded on ISQ 1 and 2, including type/performance of loading and torque of insertion.
