임플란트 잇몸 과 구강관리, 불소치약 좋지 않습니다.
임플란트를 하셨나요?
치과용 임플란트는 대부분 순수티타늄이나 티타늄 합금으로 만듭니다.
티타늄 합금은 강한 힘으로 긇으면 쉽게 상처가 날 정도로 무른 금속입니다.
일반적인 철 처럼 녹이 슬지는 않지만 산성분에 의해 쉽게 부식 될 수는 있습니다.
부식 된다는 의미는 표면이 거칠어 진다는 뜻입니다.
치아의 표면이나 임플란트 표면이 부식 되면 어떻게 될까요?
표면이 거칠어지고 음식물 찌꺼기나 세균이 잘 달라 붙고 제거도 어렵게 됩니다.
임플란트도 자연치아와 마찬가지로 치주염(잇몸질환)이 생기게 됩니다.
임플란트 주위염은 자연치아처럼 통증등의 아픈증상이 거의 없어 더 위험합니다.
꼼꼼하게 관리하고, 정기적인 검진을 통해 임플란트 주위의 건강여부를 체크하는것이 최선입니다.
정기적인 검진 전에 철저한 자가관리가 매우 중요합니다.
임플란트는 자기치아보다 더 세심한 관리가 필요합니다. 크라운 부위보다 뼈에 식립되어 있은 임플란트 주위를 특히 잘 관리해 야합니다. 임플란트는 충치가 생기지는 않습니다. 자연치아처럼 잇몸염증이 생겨 임플란트를 둘러싼 뼈를 녹이면서 파괴합니다.따라서 임플란트 주변의 잇몸을 항상 깨끗하게 관리해야 합니다.
임플란트와 임플란트 주변의 잇몸관리시 주의할 점은...
너무 강한 모의 칫솔이나 치간칫솔로 문지르며 임플란트 표면이 거칠어 질 수 있어 주의가 필요합니다.
고농도 불소치약은 임플란트 표면을 부식시켜 거칠게 하므로 주의가 필요합니다.
구강청량제 중 불소를 함유한 가글도 좋지 않습니다.
치약의 연마제 입자가 너무 굵은 것도 임플란트 표면을 거칠게 할 수 있습니다.

Abstract
OBJECTIVE:
The aim of this study was to evaluate surface changes on dental implant systems and ions release after immersion in fluoride and hydrogen peroxide.
METHODS:
Ten implant-abutment assemblies were embedded in acrylic resin and cross-sectioned along the implant vertical axis. Samples were wet ground and polished. Delimited areas of groups of samples were immersed in 1.23% sodium fluoride gel (F) or in 35% hydrogen peroxide (HP) for 16 min. Gels (n = 3) were collected from the implant surfaces and analyzed by inductively coupled plasma mass spectrometry (ICP-MS), to detect the concentration of metallic ions released from the implant systems. Selected areas of the abutment and implant (n = 15) were analyzed by atomic force microscopy (AFM) and scanning electron microscopy (SEM).
RESULTS:
SEM images revealed surface topographic changes on implant-abutment joints after immersion in fluoride. Implants showed excessive oxidation within loss of material, while abutment surfaces revealed intergranular corrosion after immersion in fluoride. ICP-MS results revealed a high concentration of Ti, Al, V ions in fluoride after contact with the implant systems. Localized corrosion of implant systems could not be detected by SEM after immersion in hydrogen peroxide although the profilometry showed increase in roughness. ICP-MS showed the release of metallic ions in hydrogen peroxide medium after contact with dental implants.
CONCLUSION:
Therapeutical substances such as fluorides and hydrogen peroxide can promote the degradation of titanium-based dental implant and abutments leading to the release of toxic ions.

Abstract
OBJECTIVES:
This in vitro study aimed to characterize the surface morphology and composition of tooth-brushed titanium casting and thereby to elucidate interactions between the metal and abrasive material in dentifrice.
METHODS:
Specimens were cast from CP Ti ingots and then mirror-finished. Two fluoride-free toothpastes containing crystalline CaHPO4.2H2O and amorphous SiO2 particles as abrasive were slurried with distilled water (15 g/30 mL). While toothbrushes were reciprocated at 120 strokes/min for 350,400 strokes, the specimens were brushed with the respective slurries under a load of 2.45 N. The brushed and non-brushed surfaces were characterized by means of SPM, EPMA, and XPS. SPM data were analyzed using one-way ANOVA, followed by post hoc Tukey test (p<0.01).
RESULTS:
Irrespective of toothpastes, toothbrushing had a significant influence on surface roughness. The CaHPO4.2H2O-containing paste produced much rougher surface than the SiO2-containing paste. Both the surfaces were chemically altered due to reactions with the respective abrasive materials. Abrading chips had dimensions of micron to submicron order. A number of chips were attached to abrasive particles.
SIGNIFICANCE:
The alterations of surface morphology and composition may affect biological responses of titanium in the oral environment. Dentifrice with lower abrasivity might be advisable for daily oral hygiene practice of patients with dental titanium devices.
