A bone height increasing device for dental implant surgery mainly includes a main body, a fixing root and a fixing base. A screw thread is formed on an outer diameter of the fixing root, and extended downward from the main body. A step portion is formed at a junction of the main body and the fixing root. The fixing base is allowed to be locked or engaged with a positioning unit, so as to fix a covering film. The fixing root has a predetermined depth. When performing a dental implant surgery, a doctor can screw the fixing root to an alveolar bone without measuring an insertion depth of the fixing root frequently, and can screw to the target position at the first time, until the step portion abuts the alveolar bone. The main body can be made in different heights in advance according to needs. Therefore, when the doctor performs the bone height increasing surgery, a bone height increasing device with the required height can be selected in advance for supporting and fixing the covering film. The bone height increasing device for dental implant surgery and the method of the present invention can not only easily fix the covering film on the alveolar bone, but also provide different heights required for bone height increasing.一種用於植牙手術之骨頭增高裝置主要包含一本體,一固定根部,及一固定座。該固定根部外徑具螺牙,自本體向下延伸,且於本體與固定根部交接處形成一階梯部。固定座可與一定位元件鎖合或扣合,以固定一包覆膜。該固定根部具有一預定長度,於植骨手術時,醫師於旋入固定根部至齒槽骨時,無須時常量測旋入固定根部之深度,而可一次旋入到位,直到階梯部抵住齒槽骨。本體可依需要,事先製作成不同高度。因此,醫師於進行骨頭增高手術時,可事先選擇所需支撐高度之骨頭增高裝置,用以支撐及固定包覆膜。本發明之用於植牙手術之骨頭增高裝置及方法,其除易於將包覆膜固定於齒槽骨上,亦可提供各種所需之骨頭增高的高度。10‧‧‧齒槽骨30‧‧‧包覆膜40‧‧‧填充骨粉50‧‧‧骨頭增高裝置60‧‧‧定位元件
