中文摘要 | 植牙除了要有咀嚼功能之外,還需要滿足審美的要求。雷射是最新發展出來處理軟組織審美的良好工具。但是雷射使用在植體周圍做組織切割手術的時候,難免會直接照射到植體,而其所引起的植體溫度變化,在何種參數條件下,將會對植體的骨整合產生影響,這是最令人關切的,也是本研究想要探討的目的。故設計了以下之實驗:將一純鈦植實心螺旋柱狀植體植入在一豬肋骨內,植體埋入骨內23mm,露出骨外7mm。固定二氧化碳雷射輸出端與被照射植體表面,成一定的距離3cm與角度約30度角。在植體側面距離頂端骨邊緣2mm處,以溫度感應探頭與高敏感熱耦溫度計紀錄有空氣吹送冷卻之實驗組與無氣冷之對照組照射不同能量之雷射的溫度變化,總共得到90組不同的溫度紀錄做比較分析。 結果顯示有空氣吹送冷卻之實驗組與無氣冷之對照組照射不同能量之雷射照射十五秒時間,每秒升溫有明顯的差異。以功率3W為例,實驗組平均每秒升溫0.66℃,控制組平均每秒升溫1.01℃。總結建議:如果使用連續波為固定的工作模式,有適當吹氣冷卻下,二氧化碳雷射可有效且安全的用虞臨床手術,來作為創造一階段植體牙齦露出修型術之理想工具。 |
英文摘要 | CO₂ lasers are usually applied in the early stage in implantology. However, the laser's variation of temperature on the implant may influence the osteointegration of the implant. In order to test the temperature variation and the efficiency of the osteointegration after laser treatment, a pure titanium implant was inserted into pig rib. The implant is drilled 23mm into the bone and 7mm left outside of the bone. The flank of the implant is 2mm away from the top of the bone edge. A 10 Watt of CO₂ laser was applied as laser light source. The experiment was divided into two groups. The first group had air-cooling during the laser irradiation while the second group without air-cooling as control. The delivery of laser energy were 3W-5W continue wave irradiated on the 1mm bone edge of the implant. The temperature change was recorded for further analysis. The results showed that in the test group, the surface temperature of implant raise to 43℃ after 8 second (s), 3s and 2s irradiated with the laser set at 3W, 4W and 5W, respectively. There was an obvious difference of the temperature raised between the average of air-cooling and no air-cooling groups irradiating by CO₂ laser. In conclusion, it was suggested that the carbon-dioxide laser with air-cooling system was a safe and efficient tool for implants surgery, and gave the dental surgeon an immediate assistance in the operation and ensured the reliability of patient treatment. |
