Abstract

Many researches have been published about the numerous factors related to the chewing ability of implant prosthesis. Most respective studies have concluded that the chewing ability of implant prosthesis is mostly fine compared to other type of prosthesis. However, some patients are not satisfied with their chewing ability of implant prosthesis. Therefore the neurologic factor, one of the factors related to dissatisfaction of chewing ability was reviewed in this study to understand the mechanism of action of mastication. Data was searched using the keywords; 'implant chewing ability, masticatory ability' in Pubmed database and reviewed. Definitions of chewing ability, factors of chewing ability are reviewed and the neurologic factor, one of the factors influencing on chewing ability, is reviewed. Mechanoreceptor of Periodontal ligament(PDL) is providing the mastication information to brainstem. Due to the absence of mechanoreceptions of PDL in implant, masticatory ability is decreased especially when chewing hard food. Masticatory muscles and mechanoreceptor in TMD may compensate the lack of mechanoreceptor of PDL in implants. Furthermore sensitivity of nerve fiber around peri-implant tissues may support the mechanoreception and sensory reaction in the implant mastication. However, further studies should be conducted to prove the relationships between neurologic factors and mastication.

임플란트 보철물의 저작능력과 관련되어 다양한 요인들이 존재하며 여기에 관해 다양한 연구가 이루어지고 있지만 대부분의 후향적 연구에서는 임플란트 저작력이 다른 유형의 보철물과 비교해서도 우수한 것으로 결론 내리고 있다. 그러나 임상적으로 임플란트 보철치료 후에 저작능력에 대해 만족하지 못하는 환자들이 간혹 있으며 이러한 저작의 불만족을 유발할 가능성이 있는 여러 가지 원인들 중 신경학적 원인에 대해 고찰해 보고자 한다. Pubmed database에서 Implant chewing ability, masticatory ability 등의 임플란트 저작과 관련된 검색어를 사용하여 검색 후 임플란트 보철물의 저작능력에 관련된 요인들 및 임상과 관련된 논문들을 선택하고 고찰하였다. 저작능력에 관한 정의, 저작능력에 관련된 요인들에 대해 고려하였으며 이러한 요인들 중 신경학적 원인과 관련된 내용을 분석 평가하였다. 치주인대(Periodontal Ligament: PDL)의 기계적감각수용기(Mechanoreceptor)는 저작운동 시 치아로부터 얻은 정보를 뇌간으로 전달하여 저작운동의 조절에 관여한다. 임플란트의 경우 치주인대의 부재로 인해 저작운동 시 저작운동 적응 능력이 떨어지며 특히 딱딱한 음식을 저작 시 이러한 현상이 두드러진다. 저작근, TMD의 mechanoreceptor 또한 저작운동에 관여하기 때문에 치주인대의 기계적감각수용기 부재를 보상할 가능성도 있으며 임플란트 주변 조직에 있는 nerve fiber가 감각능력에 관여할 수 있을 가능성에 대한 보고도 있으니 이에 대한 추가 연구가 더 필요할 것으로 사료된다.
