目的:开展了一系列对喷砂处理(MTX)微纹理化表面进行物理评价的研究,以获得形态数据以及在临床上确定其在人体内维持非埋入式愈合和单牙修复体早期负重的能力。方法和材料:对测试表面(MTX)样品和2个对照表面(Osseotite,SLA)进行三维(3D)垂直干涉扫描,并记录形态数据。测试种植体也植入到体内,在2个月非埋入式愈合后用完全处于咬中的单牙修复体(n=27)修复,临床随访监测48个月。结果:在测试表面上观察到较为均匀的微纹理化,而在对照表面上则更为随机和不规则Relatively u。MTX和Osseotite在一些粗糙度参数上相近,但MTX有更多的微沟槽更紧密的排列在一起(Stylus Yλq)且具有较大的斜率(Stylus YΔq)。对于所有植入在上颌和下颌的MTX种植体,累计寿命表为100%,没有观察到可测量的边缘骨变化。临床使用4年后的总体种植体成功率为100%。结论:MTX种植体表面表现出均匀的微沟槽表面,在非埋入式植入2个月时单牙修复体早期负重和48个月的临床使用后达到了100%的存留率和100%的临床成功率。
OBJECTIVES: A series of studies have been conducted to evaluate the physical characterization of MTX micro-textured surfaces in order to obtain morphologic data and to determine clinically that it maintains non-embedded healing and early weight bearing in single-tooth prostheses ability. Methods and Materials Three-dimensional (3D) vertical interference scanning of the test surface (MTX) sample and two control surfaces (Osseotite, SLA) was performed and morphological data was recorded. The test implants were also implanted in the body and were repaired with a single tooth restoration (n = 27) completely under bite after 2 months of non-submerged healing. Clinical follow-up was monitored for 48 months. Results: A more uniform microtexture was observed on the test surface and a more random and irregular on the control surface. MTX and Osseotite are similar in some roughness parameters, but MTX has more microgrooves arranged more closely together (Stylus Yλq) with a larger slope (Stylus YΔq). For all MTX implants implanted in the maxilla and mandible, the cumulative life table was 100% and no measurable marginal bone changes were observed. Overall implant success after 4 years of clinical use was 100%. CONCLUSIONS: MTX implants showed uniform microgrooved surfaces that achieved 100% retention and 100% post-single-tooth restoration weight-bearing and 48-month clinical use at 2 months of non-implantable implants The clinical success rate.
